Aria an experiment was carried out in south west of Khoy during 2007. Plant density in three levels (300, 400, 500 grain in m2) as the first factor and nitrogen fertilizer in five levels (0, 50, 100, 150, 200 kg per hectare) as the second factor. Result of variation analysis showed that except of leaf number and harvest index, plant density had meaningful effect on other traits. Comparison of the means showed that most grain yields by 659.2 grm-2 obtained in 500 plants per m2. The various levels of nitrogen fertilizer except of leaf number and harvest index had meaningful effect on other traits. The highest grain yield by 711.8 kgm-2 was obtained in 200 kg nitrogen fertilizer per hectare. The opposite effect of nitrogen density only had meaningful effect on protein percentage trait. The highest nitrogen percent (15/36) was obtained in 200 kg nitrogen per hectare by 300 plants per square meter density. There was a strongly correlation between grain yield by biological yield R2≤ 0.947 and between yield component. The rachis numbers by R2≤ 0.947 had most positive correlation by grain yield. By noticing results of this experiment, it is recognized that durum wheat var. Aria by 500 grain per m2 density and 200 kg nitrogen per hectare is recommendable for planting in the zone.

Patients were confirmed based on clinical and laboratory signs. Blood samples were tacked from jugular vein and were separated serum for measuring of total protein, albumin and sialic acid (total sialic acid, lipid bound sialic acid and protein bound sialic acid) levels in the serum. Mean levels of total protein in horses with strangles was higher than control group significantly (P= 0.000). But the mean serum albumin level in the patient group was higher than the control group of horses no significantly (p= 0.208). In the patient group increasing of total sialic acid, lipid bound sialic acid and protein bound sialic acid were significant (P= 0.000, P= 0.000 and P= 0.001 respectively). The correlation between serum parameters in the patient group was found that only the relationship between serum total protein with lipid bound sialic acid is significant (r = 0.521 and P= 0.004) and between the another serum parameters is not significant. In conclusion, strangles causes an increase in serum levels of sialic acid. Therefore, this issue must be considered in the treatment of these patients. Manuscript profile -

A 42-day fully randomized trial was conducted using 180 male broilers (Ross 308) divided into 4 main groups (15 birds in each) with three replicates, supplemented with the different levels of herbal essential oil as follow: I) Control (basal diet only); II) basal diet + 250 ppm oil; III) basal diet + 350 ppm oil; Ⅳ) basal diet + 450 ppm oil. The following indices were evaluated: relative weights of liver and kidney, renal injury biomarkers including urea and creatinine, hepatic biomarkers including the activities of aspartate aminotransferase (AST), alanine aminotransferase (ALT) and gamma-glutamyl transferase (GGT), protein profile including total protein, albumin and globulin and finally immunoglobulins A, G and M. Furthermore, histologic sections of liver and kidney were studied using a semi quantitative method. The obtained results indicated that clove could increase the levels of proteins and immunoglobulins dose dependently. However, the highest dose (450 ppm) could significantly alter hepatic and renal histopathology and biomarkers. Moreover, pathologic damages were more severe in liver compared to kidney. In conclusion, clove essential oil exerts beneficial effects on protein profile and immunity in broilers, however, it may damage liver and kidney in higher doses. Therefore, optimal and safe doses of the plant should be used. Manuscript profile -

The field study was carried out at a randomized complete block design with four irrigation treatments (40% deficit irrigation, 20% deficit irrigation, full irrigation (FAO Penman-Monteith method) and 20% over irrigation) and three replications with furrow irrigation method. Results indicated that impacts of deficit irrigation was significant on grain yield, biomass, weight of stems, weight of ears, weight of leaves, leaf area index, plant height, number of kernels per row, number of kernels per ear, grain protein and fat. The impacts of water stress on characteristics of maize were different in different stages of growth and were higher at the end of the growing season (grain filling stage). Maximum amount of water use efficiency in grain and fat was in T4 respectively 1.051 and 0.0549 Kg/ha and for biomass and protein was in T3 respectively 2.568 and 0.092 Kg/ha. So deficit irrigation is not recommended for maize in Kermanshah. Manuscript profile -

Therefore, the purpose of this research is to investigate the salinity tolerance of sport turfgrass caused by sodium chloride and potassium chloride salts. Method: In April, sports grass seeds were planted in an area located in Karaj province in the form of a r randomized complete block design with three replications in plots of 2 m2 (1 x 2 m2) and were cultivated with a density of 40 g m-2. The experimental treatments included sodium chloride and potassium chloride salts with concentrations of zero, 25, 50 and 75 mg l-1. After about 5 weeks of planting the seeds, salt stress was applied for one month through irrigation with salts twice a week and each time with 12 liter of salt solution and then sampling was done to evaluate fresh and dry weight of shoots and roots, total chlorophyll, proline, protein and activity of superoxide dismutase and peroxidase enzymes. Results: Data analysis showed that the treatments had a significant effect on the assessed traits. The highest fresh and dry weight of shoots (3.85-4.87 g) and roots (1.46-23.2 g) and total chlorophyll (16.96 mg g-1) were observed in the control, while the highest protein (3.73 μg mg-1) and activity of superoxide dismutase (4.62 enzyme units g-1) and peroxidase (4.12 enzyme units g-1) in 75 mg l-1 sodium chloride treatment and the highest proline content (12/ 8 mg g-1) was observed in 75 mg l-1 potassium chloride treatment, also the lowest fresh and dry weight of aerial parts (2.12-3.08 g) and total chlorophyll (12.53 mg g-1) in 75 mg l-1 potassium chloride treatment and the lowest fresh and dry weight of roots (0.59-0.96 g) were obtained in 75 mg l-1 sodium chloride treatment, and the lowest content of proline (4.48 mg g-1), protein (2.48 μg mg-1) and the activities of superoxide dismutase (3.00 enzyme units g-1) and peroxidase (2.93 enzyme units g-1) were in the control. Conclusion: According to the obtained results, sport turfgrass was able to tolerate stress conditions in 25 and 50 mg l-1 salt stress to some extent by increasing compounds such as proline, protein and antioxidant enzyme activity, but increasing the concentration of salts used, especially potassium chloride salt (75 mg l-1) had the greatest effect in reducing the vegetative traits and increasing the enzyme activity of sport turfgrass.

The subjects of this study were the effects of temperature, pH, and sugar type on the progress of the Mailard reaction in lentil protein hydrolysate, as well as its antioxidant and emulsification capabilities.Materials and Methods: The protein isolated from lentil seeds was hydrolyzed enzymatically by alkalase and mixed with glucose and lactose. Millard reaction occured at temperatures of 60 and 80 ° C and pHs of 6.5 and 11. The reaction progress was tracked over time by measuring the color intensity at 420 nm and the values of free amine groups using OPA method. The ABTS radical scavenging activity and emulsification capabilities of the final products product were analysed.Results: The results revealed that the reaction of lentil protein hydrolysate with glucose at 60 ° C and pH of 6.5 produced the most deep brown color. The findings of measuring the number of free amine groups also confirmed the results. Lactose sugar products with a lesser browning degree have the greatest effect on increasing antioxidant activity. Overall, the antioxidant activity of lentil protein hydrolyate increased from 24.18 to 60.97%, and its emulsifying function was enhanced.Conclusion: Overall, the results demonstrated that the Millard interaction between lentil protein hydrolysate proteins and peptides increases its health and functional qualities, and the product has the potential to be exploited in the formulation of functional foods.

Regardless of the number of functions performed by egg proteins in improving cakes, the current trend is to reduce the egg content or to replace eggs in order to diminish the total production cost and also satisfy consumers with specific dietary restrictions or needs.Materials and Methods: In this study, physicochemical and organoleptical properties of shortened cake prepared by substitution of egg with different levels of whey protein concentrate and modified starch in the formulation were evaluated. WPC at levels of 25%,50%,100% and modified starch at levels of 25%,50%,100%, were considered as variable treatments.Results: The results of these experiments showed that Batter Viscosity, Batter Specific volume, Cake hardness, Cake moisture, Cake volume and Cake height, have a meaningful difference as compared to the control sample in all the cases examined (P<0.05). Also pH values of the cake don’t have a meaningful difference as compared to the control sample in all the cases examined (P>0.05). All of sensory properties have a meaningful difference as compared to the control sample in all the cases examined (P<0.05).Conclusion: It was concluded that WPC alone was an appropriate substitution for egg. Although modified starch alone was not an appropriate substitution for egg, the application of modified starch at levels of 25 and 50% along with WPC could be an appropriate substitution for egg while maintaining sensory properties and improving the physicochemical properties of eggless cake.Keywords: cake, modified starch, whey protein concentrate Manuscript profile -

The aims of this study were the formulation of suitable and appropriate enteral formulation followed by its evaluation and the comparison of the rheological properties with the available commercial formula. Materials and Methods: In this applicable study from natural and available food items with caloric density of 1 kcal/mL enteral formulation containing recommended amount of macro/micronutrients has been developed. The rheological properties of prepared and commercial formulas were measured in triplicate order by using Physica Anton Paar rheometer model MCR 301. Data obtained from the rheological tests were processed using MATLAB software to determine the appropriate mathematical models. Statistical analyses, One-way ANOVA and Duncan tests (p<0.05) were performed with SPSS software. Results: The results showed that the viscosity of formulation using sodium caseinate and chiken puree was prepared and by increasing the shear rates, the viscosity was reduced, while in the case of commercial formula the viscosity was not depended on the shear rate and shear speed. There were not statistically significant differences between the viscosities of the two types of formulas. R square of Hershel bulkely model for both formulas were over 98% and hershel bulkely model was the best model to describe the flow characteristics of formulas. Viscoelastic modulus values (G' and G˝) of developed formulas were higher than the commercial sample. Conclusion: By changing the type of protein formula using a mixture of sodium caseinate and chiken puree, the rheological properties of polymeric entreal formula as compared to the existing formulas in the market containing mixtures of sodium caseinate and soy protein isolate has been changed and due to the high nutritional value and appropraite rheological properties it might be suggested to be used as nutritional support for patients who need tube feeding.

Materials and Methods: In this study, The protein extracted from lentils was first subjected to heat pretreatment (65,75, 85°C, for 15 min) and freeze-thaw (3 freezing cycles at -20 °C and thawing at room temperature). It was then exposed to hydrolysis for 3 hr by alcalase (with an E/S of 90 AU / kg protein, 55°C). Over time, the progress of enzymatic hydrolysis and antioxidant activity were investigated by O-phthaldialdehyde (OPA) assay and DPPH and ABTS radical scavenging methods and compared with the control sample (without pretreatment). Results: Pre-treatment at 75°C causes the highest value of free amino groups .The maximum DPPH (63.57%) and ABTS (36.24%) radical scavenging activity were observed respectively, for samples pre-treated at 65°C and by freeze-thaw process. Conclusion: Heat pretreatment and freezing-thawing before enzymatic hydrolysis have a positive effect on the development of enzymatic hydrolysis and production of antioxidant peptides. Based on the results of this study, the process of heat treatment of lentil protein at 65°C or freezing-thawing and enzymatic hydrolysis by enzyme alcalase was identified as an effective method in the production of lentil protein hydrolysis for use in the formulation of functional foods.

Transglutaminase treatment of low-fat milk incorporated with whey proteins makes it possible to develop a low-fat white-brined cheese with rheological properties similar to the full-fat counterpart. The objective of this study was to monitor the changes in proteolysis and lipolysis indices of transglutaminase–treated low-fat white-brined cheese during ripening. Materials and Methods: A control full-fat (3% fat), a control low-fat (1% fat) and an enzyme-treated low-fat (1% fat, 0.9 U transglutaminase/g protein, 5% whey protein isolate/L milk) white-brined cheese were produced and their physicochemical properties, proteolysis and lipolysis indices, FFA profile and organoleptic attributes were studied after 3, 20, 40 and 60 days. Results: The proteolysis and lipolysis indices of all samples showed an increasing trend during ripening (p<0.05). The development of proteolysis and lipolysis in white-brined cheese with reduced fat content was noticeably slower than its full-fat counterpart (p<0.05). Transglutaminase treatment of low-fat milk incorporated with whey proteins retarded the syneresis of resultant cheese and hereby promoted its extent of proteolysis and lipolysis (p<0.05). The decreasing rate of short-chain free fatty acids production was more pronounced than that of medium- and long-chain free fatty acids, due possibly to their contribution to production of flavor compounds. Flavor of enzyme-treated low-fat cheese was considerably improved during ripening (p<0.05) but was less appreciated by consumers than that of control full-fat sample (p<0.05). Conclusion: Transglutaminase treatment of low-fat milk incorporated with whey proteins results in a low-fat white-brined cheese with accelerated proteolysis and lipolysis and thus, more desirable organoleptic properties.

Although these antioxidants exhibit higher antioxidant activity as compared to the natural antioxidants such as ascorbic acid, but in relation to their safety and related aspects to health, there is a cause for concern. Therefore the use of natural antioxidants to replace the synthetic antioxidants is considered as an important aspect and research concerned with this matter has been regarded quite important. Peptides obtained from proteins hydrolysis are examples of natural antioxidants that have been discussed in recent researches. Materials and Methods: In this study protein hydrolysate was produced from soya protein isolate using Alcalase 2.4l and the effect of different hydrolysis conditions such as temperature, time and enzyme/substrate ratio, on degree of hydrolysis and antioxidant activity of the product were investigated in a completely randomized design and then the Fe++ chelating activity and reducing power of protein hydrolysate was evaluated. Results: The highest degree of hydrolysis was observed at 55°C after 210 minutes with the enzyme/substrate ratio of 90 Anson unit/ Kg substrate that was 30.27 %. Under these conditions, the Fe++ chelating activity reached its maximum concentration, whereas the Fe+++ reducing power showed the absorption of 0.15 that indicated lower value as compared to the highest obtained reducing power. Conclusion: The protein hydrolysate obtained from soya can act as a natural antioxidant with a high nutritional value and other biological properties and in appropriate concentrations might act as the synthetic antioxidants.

In this study, dried fruit protein was extracted using supercritical carbon dioxide method. Extraction was performed at different supercritical temperatures, supercritical pressure, and solvent ratio of carbon dioxide and methanol. According to the ANOVA results, the optimum operating condition for the extraction of protein with supercritical CO2 was as following:150.85 bar, 51.06°C, 59.80 min and methanol aqueous solvent concentration of 717.08 µL, leading to extracting of 47.53 mg protein per 10 g sample. Compared to other extraction methods, the amount of extracted protein was high with this method. In addition, less damage was done to other physical-chemical properties of the protein, including protein structure, amino acid chains, etc. Among the operating conditions, supercritical pressure had the highest effect on proteins. Therefore, the results of this study suggested that the supercritical carbon dioxide extraction can be sued as an effective method for protein extraction from plants. Manuscript profile -

As a raw material, whey has several applications in food industries and its valuable protein and lactose contents. Membrane technology, more specifically ultrafiltration (UF), is being used in dairy industry to produce whey protein concentrate (WPC) because this technology allows selective separation of whey proteins compared to the rest of its components. In this regard, the objective of this research was to investigate the effects of different operating parameter on whey protein concentration and purification process using ultrafiltration membranes. Method: Three different nanostructure Poly-Eether-Sulfone (PES) hollow fiber membranes were tested and the effects of operating parameters, temperature (43 oC), three different pressures (1 bar, 2 bar, 3 bar) and feed flow rate on the permeate flow rate, protein rejection and lactose permeation were studied. Findings: Results showed that pressure increase enhances the permeation flow rate which is more sensible at lower pressures. Moreover, high pressures have not been considered suitable considering higher fouling and lower flux recovery. Increasing feed flow rate resulted in higher turbulence on the surface of the membrane and reduces the membrane fouling and enhances the permeation flow rate even though these parameters (pressure and feed flow rate) did not have any significant effect on the protein rejection and lactose permeation. At the best operating conditions, maximum protein rejection was %91.01. Discussion and Conclusion: considering the findings, it can be concluded that UF process using PES hollow fiber membrane is capable of performing desired separation and purification of whey.

It also causes various biochemical changes and physiological responses and affects virtually all plant processes. Considering the increasing trend of salinity development and the lack of suitable lands for agriculture in the world, the use of saline resistant species or the use of compounds that reduce the effects of salinity stress and induction of resistance to stress in plants is very important. Salicylic acid, as a natural phenol, regulates growth and regulates the physiological and morphological processes of the plant. In order to evaluate the potential beneficial effects of salicylic acid on some physiological and morphological parameters of an experiment, a factorial experiment in a completely randomized design with 2 factors, salinity, including NaCl at 0, 100 and 150 mM and salicylic acid in 2 levels of 0 and 2 mM with 3 replications were conducted in the educational greenhouse of Faculty of Agriculture, Guilan University. At the end of the experiment, different parameters including plant height, dry weight and shoot weight, root dry weight and root, root length, malondialdehyde (MDA) concentration, protein content and relative leaf water content (LRWC) Made. In salinity stress, all growth parameters of plants, relative leaf water content, protein reduction and malondialdehyde increased. The application of salicylic acid increased all growth parameters, protein content, relative water content of the leaves, and eventually, salicylic acid, with its protective effect, reduced the peroxidation of lipids.

Treatments were included weed management at two levels (weedy check and weed free), the use of bio-fertilizer at four levels (non-usage as control group, seed inoculation by Bradyrhizobium japonicum bacteria, seed inoculation by Mycorrhizae fungi (Glomus mosseae) and Co-inoculation of Mycorrhizae and Rhizobium), and the use of nitrogen fertilizer (pure nitrogen from urea fertilizer) at three levels (non-usage as control group, 25 and 50 kg/ha). The results showed that among photosynthetic pigments just chlorophyll a were affected by weed treatment and chlorophyll b and carotenoids were not affected, but all of them affected by biological and chemical treatments. Additionally interaction of weeds and biological fertilizers influenced plant phosphorus content and the highest content of phosphorus (0.48%) was related to weed control treatment and co-inoculation of bacteria and fungi and the least amount (0.19%) was related to weed infested and control group of biological fertilizer. Leaf potassium content was affected by triple interaction of weeds, biological fertilizer and chemical fertilizer. The results of the analysis of variance showed that oil and protein content was affected by weed and biological fertilizer treatments and chemical fertilizer treatment only affects protein content of the seed.

The aim of this study was to compare the effect of a period of aerobic and resistance training on some metalloproteins that affect heart fibrosis in elderly mice.Materials & Methods: For the present experimental study, 27 male Wistar rats with an average age of 24 months were prepared from the center of Pasteur Institute and after weighing were randomly divided into 3 groups: control, resistance training and low intensity aerobic training. Then, the aerobic training group started training for 12 minutes with an intensity of 12 meters per minute in the first week, and at the end of the eighth week, the time reached 52 minutes and the intensity was constant. The resistance training group did 8 repetitions in the first week with 5% of body weight and in the eighth week the intensity reached 40% of body weight. Sampling was performed 48 hours after the last training session.Results: results showed that there was a significant difference between the effect of aerobic and resistance training methods on MMP-2 and the percentage of collagen deposition in the heart tissue of elderly mice. But there is no significant difference between the effect of two training methods on MMP-9.Conclusion: According to the results, the use of aerobic and resistance training on heart fibrosis is recommended in consultation with a physician, which is more recommended on the use of resistance training.

The immune system active by the cooperation of several immune sections. The immune cells and substances can identify and destroy foreign viral and microbial agents that worn out cells and cancer cells in the body. The aim of this study was to investigate the effect of high-speed sports activity on the anti-inflammatory factors lysozyme, LL-37 and HDB-2 in the saliva of obese adolescent boys. Materials &Methods: 32 male students voluntarily participated in the present study and were randomly assigned to four groups: 1) obese aerobic exercise, 2) normal weight aerobic exercise, 3) obese control without exercise, and 4) normal weight control without exercise. Anthropometric indices of height, weight and body mass index were measured. Before and after eight weeks of practice, Shatell-Run standard test was performed. Salivary samples of lysozyme, lactoferrin, lactate and C-reactive protein concentrations were taken after eight weeks of training with a frequency of three sessions per week with an intensity of 30 to 90% of maximum aerobic power. Using analysis of covariance, variables with a significance level of less than (p≥0.05) were included in the analysis. Results: The results showed that the salivary levels of lysozyme (p=0.001), LL-37 (p=0.002), and HDB2 (p=0.001) increased significantly, and the amount of increase in obese students was higher than in people with normal weight. Conclusion: The increased response of some salivary anti-inflammatory proteins following eight weeks of high-speed exercise training after increased activity may be due to the short-term responses of the immune system against the pressures caused by intense activity.

Summer sleep of these squirrels begins in late winter and continues until late February. The aim of the present study was Evaluation of Embryonic Development in Yellow Ground Squirrels (Spermophilus fulvus) and Electrophoresis Comparison of Serum and Cytogenetic Proteins of TheseSquirrels with Gray Squirrels (Spermophilus xanthoprymnus) (Mammalia: Rodentia) in Iran. Material and Method: In this project, a large number of babies were collected from several nests in May, and their development was examined in the laboratory.In this way, it was found that these squirrels give birth once a year, with 5-7 babies per calving.48 squirrels (28 males and 20 females) were collected from northeastern Iran (Mashhad and Bojnourd), western Iran (Kurdistan, Hamedan, Qazvin, and Zanjan), and northeastern Iran (Pīr Aḩmad Kandī, Kelisay-e Kandy, and Nadu village) to identify the species of ground squirrel (Spermphilus).The globulin and albumin proteins of all samples were first tested using the SDP-PAGE technique. Results: According to the results, in the sedimentary range of globulin proteins (G = Globulin), the samples collected from northeastern and western Iran formed 5 electrophoretic bands and those collected from northwestern Iran formed 11 electrophoretic bands.Besides, in the sedimentary range of albumin proteins (A = Albumin), the samples collected from northeastern and western Iran formed only one electrophoresis band and those collected from northwestern Iran formed 4 electrophoretic bands.During the karyological studies according to the method proposed by Ford and Hamerton, karyotypes were obtained from bone marrow cells to confirm the results of electrophoresis studies on the distribution of two of these squirrels in the collection areas in Iran.The results indicated that the karyotype of the samples collected from northeastern Iran (Mashhad) and western Iran (Qazvin, Hamedan, Zanjan, and Kurdistan) had 36 diploid chromosomes (2n = 36) and that the karyotype of the samples collected from northwestern Iran (Mako) had 42 diploid chromosomes (2n = 42). Conclusion: According to the results of electrophoresis and karyological methods, among ground squirrels, Sprmophilus fulvus species are distributed in northeastern and western Iran and Spermophilus xanthoprymnus species are distributed in northwestern Iran.

During a survey, Out of 198 samples of cucurbit plants that were collected from the different fields and cucumber greenhouses in khorasan province, 39 samples were infected by CGMMV in DAS-ELISA using specific polyclonal antibody (The rate of infection was 19.7%). Using specific primers which were designed based on the CGMMV coat protein (CP) gene sequence; a fragment with 486bp length was amplified by reverse transcription polymerase chain reaction (RT-PCR). The CP gene was cloned, sequenced and compared with the sequence of homologous gene of other CGMMV isolates recorded in GeneBank. Phylogenetic analysis using 486 nucleotide long sequences of coat protein gene showed that all CGMMV sequences can be placed into two groups: I and II. Members of group I were divided into two subgroups: A, B. Iranian isolate (kalat) was classified in the group IA. The result showed it had high homology with the other isolates (the highest homology could reach 97.9% in nucleic acid level). As well, phylogenetic tree based on CP amino acid sequences was established and the highest amino acid homology was 98.1%. This is the first report of CP sequence of CGMMV Iranian isolate, determination of its phylogenetic relationship and comparison of its nucleotide and amino acid sequences with those of the other isolates of CGMMV obtained from GenBank.

(Dip.: Tephritidae) is the most important pest of the cherry and sour cherry orchards with noticeable annual yield damage. This research was conducted in two 4.5 hectare cherry orchards located at two parts of Isfahan province (Najafabad and Khomeinishahr), Iran. A comparison was done among different types of the fly attractants presented in different traps to find the most effective one in capturing the adults of cherry fruit fly and the peak of flight activity. The treatments were including the two food based traps containing hydrolyzed protein solution and Ammonium bi-carbonate presented in 1.5 L. plastic bottle and McPhall trap respectively. The Rebell traps with no attractant and two pheromones prepared from Green Universe and Russel companies were provided in delta traps. Results showed that in the first location (Najafabad) the highest number of flies with the mean of 28.75/trap were attracted to Rebell trap and the lowest with the mean of 0.5/trap in Russell pheromone trap. In the second location (Khomeinishahr), the Rebell traps were also the most attractive (mean=15.25/trap) and the hydrolyzed protein solution with no capture was the least effective attractant. It is concluded that the Rebell traps can be recommended as a part of IPM for cherry fruit fly. Manuscript profile -

(Diptera: Stratiomyidae), can effectively convert the organic wastes into a nutrient-rich biomass and appropriate for animal feed, the composition of larve largely dependent on the composition and structure of the side stream which are used. The polyphage diet and the quality of the larvae's macronutrients (mainly lipids and proteins) make them suitable candidates for different applications such as organic side-streams management and using as protein sources in animal feed. In the present study, BSF larvae were reared on feed substrates composed of Mix of fruit and date pulp, Mix of fruit and olive pulp, mix of waste fruit and bread and waste fruit which is a readily available and cheap source of agriculture,s by product in Iran. The dry matter, crude fat, crude protein and ash of the BSF larvae fed each feed waste organic were quantified by chemical analyses. Larval weight, survival and feed conversion were also recorded. The results showed that the mixed of date and fruit pulp and the mixed of olive and fruit pulp are suitable diets for BSF rearing. Our findings may provide important supporting information to support the use of BSF larval meal as potential new source of nutrient- rich and supportable animal feed ingredients to substitute expensive and limited protein sources such as fishmeal and soya beanmeal.

Used hazelnut was Gerd-e-Eshkevarat. To determine the best drying temperature for hazelnuts, a factorial experiment in a completely randomized design with two factors; dryer air temperature in three levels (40, 50 and 60°C) and fruit type in two levels (with and without skin) in three replications was applied. Fruits were dried in a thin layer with a laboratory dryer. To determine the specialized energy required for drying hazelnut in each treatment, electrical work equation in dryer (heater work + fan work) was used. Peroxide and acidity of hazelnut oil were measured by standard institute and Iran industrial research methods. The results showed that the interaction effect of fruit type and temperature was not significant on fruit oil percentage, but other traits were influenced by interaction effect of treatments. The highest percentage of protein (13.62%) was obtained in roasted hazelnuts with 60°C and with skin. The highest and lowest percentage of oil acidity (0.28 and 0.11%) were recorded in roasted hazelnuts with 50°C with and without skin, respectively. Peroxide numeral value (8.25 and 1.30) was obtained in roasted hazelnuts with 40 and 60°C with skin, respectively. Overall, 60°C was the most suitable temperature for drying hazelnut fruit which resulted to enhance most physiologic and taste traits. Manuscript profile -

To examine the effects of plant density and weed control methods on vegetative and reproductive characteristics and yield of kidney beans MoreAn appropriate plant density and weed control method is highly influential factor in the production of kidney beans with high yield. To examine the effects of plant density and weed control methods on vegetative and reproductive characteristics and yield of kidney beans, the Research Center of Agriculture in Khoy –W. Azarbaijan conducted a factorial experiment in the form of randomized complete block design (RCBD) with three replications from 2018 to 2019. In this study plant density at three levels of 20, 25 and 30 plants per square meter, and weed control methods at four levels of non-control, selective herbicide (bentazon ), manual control and application of general herbicide (paraquat) were chosen. The results showed that there was a significant relationship between plant density and weed control methods and lateral branches, number of pods per plant , grain yield, biological yield and protein yield; however there was no meaningful relationship between plant density and weed control methods and other characteristics such as plant height and the percentage of grain protein. The highest grain and biological yield were obtained at a planting density of 30 plants per square meter and manual weeding; afterwards, the manual weeding was followed at 3391 and 15275 kg/ha respectively and the highest percentage of grain protein at a density of 20 plants per square meter together with manual weeding was obtained at the level up to 24.8 %. The results also indicated that the manual control method was relatively effective and proved to be better than all other methods, with the consequence that herbicides by themselves were not effective in controlling weeds of kidney beans. Production of grain yield with a maximum density of 30 plants per square meter indicated that a positive response of kidney beans to the high density of the plants. Manuscript profile -

Mixed analysis of variance (ANOVA) test was used at a significant level (P<0.05). hs-CRP level significantly increased only in the HIIT2 group (p<0.05). No significant difference was observed between the groups (p=0.377). The IL-6 significantly decreased only in the HIIT2 group (p<0.05). A significant difference was observed only between the HIIT2 group and the control group (p=0.031). The mean of TNF-α showed a significant decrease only in the HIIT2 group (p<0.05). a significant difference was observed between the HIIT2 group and the control group (p=0.042). It seems that medium-term HIIT training reduces inflammatory indicators (IL-6, TNF-α) compared to short-term and probably has a role in reducing the incidence of heart and metabolic diseases in these people.

From a total of 42 soil samples examined through selective sodium acetate detention, 160 Bt isolates were separated. After planting the colonies, specific staining and microscopic identification were observed in 40% of isolates crystalline proteins that are toxic to many insects. Molecular study showed that in 12 isolates, gene Cry1 existed. Genetic structure tests for presence of 3 gene Cry1A (including Cry1Ac, Cry1Ab, Cry1Aa) and genes Cry1I, Cry1F, Cry2, Cry 9, Vip3Aa was carried out using the 8 pair of specific primers. Genes Cry1Ab, Cry2, Cry F were observed in all isolates, but the genes of Cry1Aa, Cry1I, Cry1Ac had very low frequency (Lower than 20%) or not found in any of the isolates. The results of this research could be very useful for tracking native Bt isolates that contain effective crystalline proteins for insects Manuscript profile -

The experiment was conducted on quince cv. Isfahan seedlings grafted on quince rootstocks under orchard condition. In early spring, three-years-old young plants were sprayed twice with Bion (400 mg/l) in 4-days intervals and four days after the last spray, young leaves were collected for enzymes extraction and quantification. Also, phytotoxic effects of Bion were studied throughout the time course of the study in orchard. Based on the results, Bion did not induce any phytotoxicity effects on quince. Bion treatment increased polyphenol oxidase and peroxidase activities but did not affect on catalase activity. It is concluded that elevation of oxidative enzymes are a part of biochemical mechanism of Bion-mediated defense in quince but catalase enzyme activity, which dismutase reactive oxygen species, does not change.

Unused food (whether as waste or by-products referred to as food residue) is a source of carbohydrates, lipids, proteins, vitamins, minerals and bioactive compounds. which can be used to prevent them from being thrown away in an alternative or secondary cycle. Current investigations in the direction of using food residues for single cell protein bioengineering, addressing aspects of production, nutrition and safety, are the main perspectives of SCP production. SCP are obtained from various microorganisms, including fungi, bacteria, yeasts and algae, in pure form or a mixture of these. SCPs generally contain a high percentage of protein and are a source of essential amino acids including methionine, threonine and lysine. Using food residues as a substrate for SCP production reduces production costs. However, the challenges of optimization on an industrial scale remain strong. The use of food waste and agricultural by-products can be a promising alternative for protein production. Manuscript profile -

The purpose of this study was to compare the active and inactive recovery after a session of high intensity interval training (HIIT) on the response of C-reactive protein (CRP), cortisol and IL-6 (IL6). Methods: The statistical sample of this study was 20 footballers with a mean age of 18.9 ± 0.5 years, weight 1.7 ± 1.7 kg, height 176 cm2.2, body mass index of 22.4 ± 1 kg / m2 and the maximum consumed oxygen was 51.3 ± 2.5 ml / kg body weight, which was randomly selected among the soccer players of Esteghlal'e Novin team in south of Tehran. Subjects were participated in two groups with two tests, active recovery and inactive recovery. Blood samples were collected from both groups before and immediately after recovery then, cortisol, and IL-6 and CRP levels were evaluated using ELISA technique. Results: There was no significant difference between active and inactive recovery after HIIT activity on CRP and IL6 responses. While there was a significant difference between active and inactive recovery after HIIT activity on cortisol response (P <0.05). Conclusion: The results of this study showed that active recovery after HIIT activity could affect cortisol response. Therefore, active recovery would be more effective than passive recovery.

Due to the formation of different strains of SARS-CoV-2 by mutations, and their catastrophic effect on public health, the study of the effect of mutations by scientists and researchers around the world is inevitable. According to available evidence, the S494P variant is observed in several SARS-CoV-2 strains from Michigan, USA. To investigate how the S494P natural mutation alters receptor binding affinity in RBD, we performed structural analysis of wild-type and mutant spike proteins using some bioinformatics and computational tools. The results show that S494P mutation increases the spike protein stability. Also, applying docking by HADDOCK displayed higher binding affinity to hACE2 for mutant spike than wild type possibly due to the increased β-strand and Turn secondary structures which increases surface accessibly surface area (SASA) and the chance of interaction. The analysis of S494P as a critical RBD mutation may provide the continuing surveillance of spike mutations to aid in the development of COVID-19 drugs and vaccines. Manuscript profile -

Its binding to testosterone reduces bioavailable testosterone and causes diseases of the male reproductive tract such as infertility, erectile dysfunction and prostate cancer. Objective: In this in Silico study, the potential of several compounds present in Tulang honey against SHBG protein for the treatment of infertility has been investigated. Materials and methods: The six compounds in Tualang honey, Catechin, Ethyl oleate, Fisetin, Hesperetin, Kaempferol and Luteolin were obtained from previous studies and the PubChem pharmaceutical database. The binding energy and type of protein-ligand interactions were investigated by molecular docking of these compounds to SHBG protein. AutoDock Vina version 1.1.2 software was used to perform molecular docking and Discovery Studio v21.1.0.289 software was used to analyze molecular docking results. Then SwissADME and admetSAR 2.0 web servers were used to evaluate the pharmacokinetic properties of these compounds through ADMET predictions. Results: The binding energy obtained from molecular docking showed that Luteolin with a score of -10 kcal/mol binds to SHBG protein, and has more hydrogen-hydrophobic interactions than other studied compounds as well as compounds that have been worked on in recent papers. Catechin and Fisetin also showed an acceptable result. The study of ADMET and bioavailability radar showed that although these compounds have physicochemical properties for use as drugs, they have the potential to inhibit some cytochromes and toxicity for certain organs and DNA or other genetic material in the body that should be considered in the use of these compounds as drugs. Discussion and conclusion: Using this in silico study, several suitable molecules of natural origin against the SHBG protein were identified, which showed potential for the treatment of male infertility.

For this propose 24 old women, 60 to 70 years old randomly selected and divided into experimental (n=12) or control (n=12) groups. The experimental group performed step aerobics training with an intensity of 60 to 70% of heart rate reserve, 3 sessions per week for 12 weeks. Plasma BDNF and tau phosphorylated protein level was measured with an ELISA kit. There was no significant difference between the levels of tau phosphorylated protein in the experimental and control group in different stages (p <0.05); Also, the results of repeated measures analysis of variance showed that despite the decrease in the level of tau phosphorylated protein, but there was no significant difference between the levels of this index in different stages of the study (p = 0.182). The plasma BDNF level of elderly women in the post-test stage (12 weeks) in the experimental group was significantly higher than the control group (p = 0.018). Also, plasma BDNF levels after 8 and 12 weeks in the experimental group were significantly higher than the pretest (P values were 0.021 and 0.004, respectively).These results suggest that the possible positive effects of exercise in the elderly with reduced cognitive function are not due to a decrease in the phosphorylated Tau protein and that neurogenic pathways are activated in this way.

Finding strategies to reduce the effects of terminal droughts of chickpea under dryland conditions in this area would be very beneficial. To evaluate the effects of foliar application of glycine betaine (GB) and salicylic acid (SA) on yield and yield components of two chickpea cultivars under rainfed condition, a factorial experiment based on randomized complete block design with three replications was conducted at Razan town of Hamedan province in 2017- 2018 year. In this experiment, treatments were the use of distilled water as control, three levels of glycine betaine (200, 400 and 600 mM) and three levels of salicylic acid (250, 500 and 750 µM) on two cultivars of chickpea (Hashem and Saral). The results showed that foliar applications of plants with GB and SA resulted in significant effect on all traits under study, except number of seed in pod. The highest of seed yield was observed in Hashem (168.05 g.m2) and Saral (178.55 g.m2) cultivars with foliar application of 600 mM glycine betaine. The treatment of 600 mM of glycine betaine increased seed yield of Hashem and Saral cultivars by 17.6 and 18.5 percents, respectively. There were significant differences between the two cultivars under study. Maximum of number of seed per plant, seed yield, biological yield and harvest index were belonged to Saral cultivar, while plant height, weight of 100 seed and percent of protein seed observed in Hashem cultivur. According to the results of this study, it can be concluded that the application of glycine betaine on yield and yield components of chickpea under rainfed conditions was more effective than using salicylic acid. It can be said that foliar application of chickpea with GB and SA would improve the performance of chickpea cultivars and rainfed conditions. Futher studies are sudgested to substantiate the results.

The experimental design was a split – plot based on randomized complete block with three replications. The main plots were four levels of nitrogen (0 , 75, 150 and 225 kg/ha) and sub plots were three levels of plant density (75000, 100000 and 125000 plant/ha). The results showed that increasing nitrogen levels and plant density, plant height, percentage crude protein and total protein production (ton/ha) were increased. By increasing plant density, stem diameter, leaf and ear weight decreased while they increased with increased nitrogen levels. The highest forage yield obtained at nitrogen level 150 kg/ha (46 ton/ha) and 100000 plant per hectare (40.27 ton/ha). The highest total protein production (7 ton/ha) obtained at nitrogen level of 150 kg/ha and plant density of 125000 plant/ha. Manuscript profile -

Treatments consisted of phosphate fertilizer with three levels (0, 75 and 150 kg/ha as triple super phosphate) and Pseudomonas putida strains with four levels (M21, M5, M168 and control). The results showed that use of phosphate fertilizers increased the soil pH during growing season while bacterial inoculation adjusted soil pH. The bacterial inoculation increased amount of crude protein, digestible protein, acidic and alkaline phosphatase activity compared to non-inoculated treatment, but it decreased crude fiber of the forage. Clover forage yield, protein yield and phosphorus content of foliage also were influenced by the interaction of bacterial strains and phosphate fertilizer. The highest forage and protein yield were obtained by using strain M5+150 kg P ha-1. Significant increases in forage and protein yield were found to be 16.49% and 8.01%, respectively, as compared with non-inoculated treatment. Based on the result of this experiment, application of 150 kg P ha-1 and Pseudomonas putida strain M5 inoculation can be used to obtain highest forage yield and quality of berseem clover as second crop in the experimental site.

It was conducted in split plot arrangement based on randomized complete block design with three replications. Planting dates (June, 5- June, 20 and July, 5) were assigned to main plots and hybrids (BC404، KSC320، OSSK552، KSC500، OSSK713 and KSC704) to sub plots. Results indicated that there was no significant difference for growing degree-days (GDD) requirements from planting to germination among hybrids and planting dates. However, KSC704 hybrid in the first planting date needed the highest GDD during its different growth stages. KSC 500 hybrid with 6.31 (t/ha) and OSSK 713 hybrid with 6.48 (t/ha) produced the highest grain yields. The highest number of grains per ear row belonged to KSC320 Hybrid (18.83).

Thus, field experiment was carried at Dezful, using maize single cross 701 cultivar, in a randomized complete block design for one years. The experiment consisted of seven treatments: control, foliar spraying with chelate or sulfate of iron with a concentration of three mg.L-1, foliar application of sulfate or chelate of zinc with a concentration of mg.L-1, foliar application of combined sulfate or chelate of zinc and iron with a concentration of 1.5 mg.L-1 for each element. Results at the experiment showed that the effect of different foliar treatments on all factors, except cob weight and grain manganese concentration, were significant. The highest grain yield was 9520 kg.ha-1 and biological yield (37.73 ton.ha-1), in the combined foliar application of iron and zinc, was 13% increase, as compared to the control. There was no significant difference in grain yield between the two sources of iron chelate and iron sulfate. The highest concentration of iron grain was observed by using foliar application with ferrous sulfate at a concentration of 3 mg.L-1 and the highest concentration of zinc foliar application observed with zinc sulfate at a concentration of 3 mg.L-1. The highest percentage of protein content was observed by using foliar application of iron and zinc. The results of this study showed that foliar application of corn with iron and zinc increased seed yield and improves its quality. There were no significant difference between the two sources of sulfate and chelate applications, while in some cases the use of sulfate source showed better results. Manuscript profile -

Suplimental irrigation (rainfed, suplimental irrigation at 50% flowering and supplemental irrigation at 50% flowering+ 50% poding) in the main plots, super absorbent polymer in subplot and cultivars (Arman, Azad, Hashem, Adel and ILC482) the sub-subplots were located. The highest grain yield and protein yield were obtained in supplementary irrigation in two stages (50% flowering + 50% poding) with super absorbent application, by avrege of 3890 and 870 kg.ha-1, respectively, which were 24% and 21% higher than control, respectively. The highest leaf greenness (39.22), pods per plant (22.1), seed weight (52.4) and biological yield (5413.5) were related to two-stage irrigation. The highest number of pods per plant (27.7) was observed in Hashem cultivar and superabsorbent application, which was 34% more than non- super absorbent in same cultivar. Results of genotype× super absorbent showed that the highest grain yield (4159 kg.ha-1), grain nitrogen percentage (3.69) and protein yield (960 kg.ha-1) were obtained under super absorbent and Adel cultivar conditions. Based on the results, application of supera bsorbent increased grain yield and protein yield of chickpea genotype in rain-fed conditions. By improving physiological traits, associated with drought tolerance, the use of supplemental irrigation method in areas that make this possible, especially if combined with the application of super absorbent polymers, can increase seed yield in chickpea.

Experimental treatments included conventional and minimum tillage, fertilizer treatment at three levels of 0, 150 kg urea ha-1 and 150 kg urea ha-1 + nitrapyrin and wheat cultivars (Arg and Omidbakhsh). Tillage systems were effective on the studied traits and that the highest amount of chlorophyll (5.18 mg.g-1 FW) and leaf area index (3.78) were obtained in minimum and conventional tillage, respectively. The highest grain protein content (170.7%), grain yield (668.3 kg.ha-1) and harvest index (42.51%) were obtained in minimum tillage and 150 kg urea ha-1 fertilizer + nitrapyrin. Application of urea + nitrapyrin increased grain protein, 1000-grain weight and harvest index. Both Arg and Omidbakhsh cultivars obtained the highest plant height (102.16 and 104.66 cm, respectively) and leaf area index (3.88 and 3.98, respectively) in 150 kg urea ha-1 treatment. The three-way interactions of tillage, fertilizer and cultivar also had a significant effect on leaf dry weight, grain yield and biological yield. In minimal tillage, Omidbakhsh cultivar in 150 kg urea ha-1 + nitrapyrin fertilizer treatment showed better grain yield and biological yield than other treatments. According to the obtained results, in minimal plowing conditions, Omidbakhsh cultivar and application of urea + nitrapyrin is recommended. Manuscript profile -

Three durum wheat genotypes (SAJI, BCR and STJ) with three sowing dates, prior to effective rainfall (the amount and time of effective rainfall were 33.2 and 34.5 mm, and 26 October, and 5 November for two years of experiment, respectively). 15 days after effective rainfall and 30 days after effective rainfall were evaluated for four densities of 250, 350, 450 and 550 plant per square meter. Traits like number of spikes per square meter, 1000 kernel weight, seed and biological yield, harvest index and absorbed radiation percentage were measured. The results of mean comparisons of simple effects showed that the number of spikes per square meter in the planting date before rainfall was more effective than two other planting dates. Biological yield and absorbed radiation percentage were 26.9 and 12.9 percent higher respectively in second year of experiment as compared to the first year. Comparison of interactions means showed that STJ genotype under 250 seeding density and 15 days sowing date after effective rainfall, produced highest 1000 kernel weight, while SAJI cultivar at 550 seeding density and planting date before effective rainfall showed the highest kernel yield. The SAJI cultivar showed highest biological yield under 450 seeding density and planting date before effective rainfall. For all three genotypes, the highest percentage of radiation absorption was observed when sowing date used before rainy season using 450 and 550 seeding densities. In this study all genotypes showed the highest traits values at first planting date and under 450 seeding density. The highest values of protein and chlorophyll content were observed using 350 seeding density. Manuscript profile -

To assess the effect of salicylic acid on its morphological and agronomical traits under different irrigation intervals, a split plot experiment based on randomized complete block design with four replicates was performed in Galeh-Gang region in Kerman province, Iran. Three different irrigations with 6, 9 and 12 day intervals, assigned to main plots and four salicylic acid concentrations (0, 0.5, 1 and 2 mM) to sub plots. Salicylic acid spraying was done three times at five leaf, flowering and podding stages. The results indicated that most of the morphologic and agronomic characters of guar were influenced under different irrigation intervals. Leaf area index, number of pods per plants and number of seeds per pod were decreased when drought stress occured. Spraying plants with salicylic acid increased almost all characters under study. While, the highest number of pods per plant, seeds per pod were obtained at 2 mM and leaf area index at 1 mM salicylic acid treatments. Irrigation interval by salicylic acid interaction was significant for specific leaf area, 1000 seed weight, seed protein content and seed yield. The highest seed yield (1245.25 kg.ha-1) was belonged to the irrigation of 6 day interval and 1 mM acid salicylic treatment. As a whole it can be concluded that use of 1 mM salicylic acid treatment might increase drought tolerance of guar and prevent yield reduction during drought stress. Manuscript profile -

Due to the important nutritive role of wheat in these countries, researchers are trying to produce wheat grains with higher nutrients contents like iron, zinc, ascorbic acid and protein, along with low phytic acid content and Zn/PA ratio to limit malnutrition. Because of significant role of Zn on the metabolism of carbohydrates and proteins; the effects of foliar application of Zn on the quality and yield of wheat grains was studied. In this study six wheat cultivars were planted at a farm in Tastaghar village located in Hashtrood county, during early fall of 2016 in split plot experiment based on randomized complete block design. Treatments used were six wheat cultivars (Baran, Tak-Ab, Sardari, Ohadi, Homa and Azar 2) and leaf foliar application of Zn with four levels (control, during beginning of stem elongation and stem elongation+anthesis stages). Zn foliar treatments were applied in the evenings by a portable pump sprayer. The results revealed that the foliar application of Zn increased seed yields of the cultivars under study. Moreover, protein, Zn and ascorbic acid content of the seed were also increased significantly (P≤%5). However, phytic acid content and Zn/PA ratio were decreased as compared to control. Overall it can be said that, foliar application of Zn had positive impact on the seed yield, proteins, Zn and ascorbic acid contents. It can be concluded that the foliar application of Zn on wheat would improve the seed yield and some qualities of wheat cultivars. It would be advisable to extend continuing this kind of studies to overcome malnutrition problems of area. Further studis is recommended to substantiate the results. Manuscript profile -

The first factor consisted of four durum wheat genotypes and the second factor of levels two zinc sulfate application (control and foliar application of Zn on soil at stem elongation + seed filling stages). The results showed that application of zinc sulfate could increase biological and seed yields of RCOL genotype by 2 and 4 times compared to control respectively. The effects application of zinc sulfate on biological and seed yields of other genotypes were not significant. Based on the results obtained from this study the highest increase in seed weight was 20.7% in the RCOL genotype by Zn application. The highest reduction in phytic acid to zinc molar ratio was observed in Ege-88 genotype and this ratio was decreased by 52.2 percent in the control to 8.4% due to Zn application. This may indicate different responses of durum wheat genotypes to the zinc deficiency in the soil. The results also showed that the number of seed per spike was increased by 22.7 percent and phytic acid was decreased by 62.3 percent due to the application of zinc sulfate. Also, application of zinc sulfate increased Zn concentration in seed from 29.9 mg.kg-1 to 64.7 mg.kg-1 in control. In general, however, the application of zinc was not the reason of seed yield improvement of all genotypes studied but it improved seed yield qualities. It can be concluded that use of Zn is an appropriate method to improve the qualitative and quantitative traits of seed yield. To confirm these results other studies are needed. Manuscript profile -

Treatments were three levels of ascorbate (control, 5 and 10 mM) and three levels of temperatures (15, 25 and 35 °C). Parameters under study were germination indices, production rates of antioxidant enzymes, proline and protein. The results of experiment indicated that ascorbate application that of raised proline content. Application of ascorbate resulted in enzymes reduction at 15°C more than 25°and 35° temperatures. Its application also reduced protein denaturation. Since sesame is a warm season plant, it seems that increasing antioxidant enzymes at 15°C is due to higher production of free radicals. The positive and significant correlation between antioxidant enzymes and germination indices represents their direct relationships. According to the results of this experiment, it seems that the application of ascorbate had positive effect on germination indices and reduced the effects of improper temperatures; it also benefited seedling growth of sesame.

Water stress was in three levels: 80 mm evaporation (normal irrigation); 120 mm evaporation (low water stress); 160 mm evaporation (high water stress) from evaporation pan of class A which were assigned to main plots and three cultivars of safflower (Goldasht, Spiny Sina and Faraman) and two levels of Brassinosteroid, control and 10 -7 mol. in sub plots. The reasults showed that water stress decreased stomatal conductance, photosynthetic rate, sub-stomatal CO2, water-use efficiency, chlorophyll content index (SPAD), seed yield, leaf soluble protein and transpiration rate. The results also showed that use of brassinosteriod, increased photosynthetic parameters and reduced transpiration. Irrigation at evaporation of 80 mm from pan, resulted in the maximom amount of transpiration and stomatal conductance to the Faraman cultivar, sub-stomatal CO2 to Sina spiny cultivar and chlorophyll content index (SPAD) to Goldasht cultivar. Irrigation at 120 mm evaporation from class A pan resulted in the maximum amount of transpiration and stomatal conductance to Goldasht cultivar, while the highest sub-stomatal CO2, belonged to Sina spiny. Irrigation at 160 mm evaporation from class A pan resulted in the maximum amount of transpiration, stomatal conductance, chlorophyll content index (SPAD) and the sub-stomatal CO2 to Goldasht cultivar.

Thus, improving its forage quality through agronomical managements seems to be of high importance. To evaluate quality traits of forage maize cultivars in response to plant densities, a factorial experiment based on RCBD with three replications was carried out at the Research Station of Faculty of Agriculture, University of Maragheh during 2013-2014 growing season. The first factor was plant density with three levels (93000, 105000 and 119000 plant.ha-1) and the second factor was maize cultivars with five levels (Zola, Simon, NS, 540 and 370). Results of the experiment indicated that dry matter production was affected by the interaction of plant density and cultivar, where cultivar 540 produced the highest dry forage (980 g.m-2) by density of 119000 plant.h-1 and cultivar NS the lowest (933 g.m-2) dry forage by density of 93000 plant.m-2. However, all cultivars under study produced higher dry matter under higher plant densities. It was also observed that Zola cultivar, with 638 g.kg-1 of hemicellulose, had the lowest forage quality. Other cultivars were in the same statistical group. Phosphorous content of forage was in its highest value in 93000 plant density, while calcium content was not affected by plant density. Lower plant densities resulted in higher crude protein content. Cultivar no. 540 produced the highest crude protein yield (kg.ha-1) suggesting its superiority to the other cultivar. This cultivar can be recommended for growing in this region and other regions with same climatic conditions for producing high quality and quantity of maize forage production. Manuscript profile -

The Siberian sturgeon is a good species for aquaculture due to its good growth in different sizes in breeding systems and its ability to reproduce sexually in captivity. In this study, the chemical composition of fillet and some biochemical and enzymatic indicators of blood serum in Siberian sturgeon in different weights were investigated. Fish in 5 groups of mean weight of 0.5-0.7 kg, 2.5-2 kg, 6-7 kg, 10-12 kg and 15-17 kg and with 3 fish from each group were studied. The results of the present study showed that with increasing weight and size of fish, the amount of protein, ash and fiber decreases and the amount of fat increases (P <0.05), but the amount of moisture at different weights does not differ (P> 0.05). The results of the present study showed that fish weight affects the biochemical parameters of fish serum, so that with increasing weight, the amount of cholesterol, triglyceride, urea and iron increases (P <0.05), but the amount of albumin, calcium, sodium and potassium did not change (P> 0.05). While the highest amount of protein in the weight group was 6 to 7 kg. Also, the level of stress indices (glucose and cortisol) increased with weight gain and the amount of serum enzymes was higher at low weights (P <0.05). The results of the present study showed that the size and weight of fish affect the chemical composition of fillet and some biochemical and enzymatic factors of fish blood serum. Manuscript profile -

Gelatin-based films enriched with different concentrations of CAO were prepared and examined. Incorporation of CAO at concentrations of 0-1.5% resulted in the decreasing in tensile strength (TS) of the films. Water vapor permeability (WVP) was increased in the film added with CAO at a level higher than 0.5% (P<0.05); However, film solubility and L*value decreased. Moreover, when CAO was incorporated the films showed the lowered light transmission in the visible range. Films incorporated with CAO had an inhibitory effect in a concentration-dependent manner against Staphylococcus aureus, Listeria monocytogenes, and Escherichia coli.

Based on their spectral characteristics, PBPs are divided into three types: Allophycocyanin, phycocyanin and phycoerythrin. PBPs, apart from their special function as sunlight-receiving antennas in the photosynthesis process, can be used as food dyes, nutrients, cosmetics, pharmaceutical industries and fluorescent probes in immunofluorescence analysis. Since PBPs have antioxidant, anti-tumor effects, as well as potential anti-inflammatory and anti-diabetic properties, in this review article, an attempt was made to investigate the properties and medicinal potential of PBPs along with their structural features. The results of the review of recent articles showed that the PBP part of proteins is very sensitive to environmental stress and this issue limits their use in the food industry. Therefore, it is necessary to use protective and coating materials to preserve the color. Consequently, they can prevent the denaturation of the protein structure, which not only increases the antioxidant properties but also increases the half-life of the food. Manuscript profile -

Sick horses were detected by clinical and laboratory (culture of nasal discharge) findings. Blood samples were subsequently collected from the jugular vein in all horses and serum was separated. The concentration of acute phase proteins (Haptoglobin and Serum Amyloid A) were measured in all samples. Mean Serum Amyloid A in affected and healthy horses was 2749.13±569.95 mg/dl and 1602.97±357.76 mg/dl respectively. Mean serumic levels of Haptoglobin in affected and healthy horses was 1258.20±244.01 mg/dl and 721.97±187.18 mg/dl respectively. Average of both parameters in affected horses was significantly higher than the healthy group (in both p=0.000). There was no significant correlation between the measured parameters in diseased horses (p=0.158 & r=0.269). In conclusion, strangles induces increase in the serumic concentration of acute phase proteins which must be considered in the treatment of affected horses. Manuscript profile -

The objective of this study was to evaluate available data in each milk record such as fat, protein and their ratio, somatic cell count (SCC) and the history of dairy cows in order to determine pregnancy risk (PR) till 120 days in milk (DIM). Therefore, the information of 1,279 primiparous and multiparous Holstein dairy cows was collected on days 30 and 60 of DIM and near the first artificial insemination (AI) postpartum. The results illustrated the amount of milk fat, protein and FPR on day 30 of DIM in non-pregnant and pregnant groups were (2.67±1.2, 2.62±1.04 and 1.01±0.4) and (2.87±1.16, 2.76±0.95 and 1.03±0.36), on day 60 of DIM were (2.87±1.06, 2.7±0.86 and 1.06±0.35) and (2.97±1.15, 2.73±0.9 and 1.08±0.36), and near the first AI were (2.62±1.2, 2.53±1.04 and 1.03±0.4) and (2.8±1.24, 2.63±1.01 and 1.06±0.5), respectively, in which their effects on PR till 120 DIM were significant at two sampling times (p < /em><0.05). The effect of SCC at day 60 of DIM on PR till 120 DIM was also significant (p < /em>=0.023); but none of the milk constituents and SCC had constant effect when analyzed by Logistic regression. Seasons of calving (p < /em>=0.02) and AI (p < /em>=0.00), previous DIM (p < /em>=0.001) and milk production (p < /em>=0.016) were analyzed by COX model and it was demonstrated that only previous DIM (p < /em>=0.021, Odds ratio=0.985) and season of AI (p < /em>=0.040, Odds ratio= 7.5) had significant effect on pregnancy till 120 DIM. The result of the present study shows that the effect of previous DIM and season of AI are significant on pregnancy till 120 DIM, but milk constituents had no effect on it. Manuscript profile -

Acute phase proteins are a group of serum proteins whose concentrations increase in response to infections, inflammation, trauma, and neoplasia. Therefore, in the present study, we evaluated the serum levels of serum biomarkers, fibrinogen and total protein concentration along with the nutritional behavior of horses during diet change. For this purpose, two types of diets, including forage (first treatment) and mixture of forage with concentrate (second treatment) were used for each horse for fifteen consecutive days. Complete blood cell counts as well as serum levels of fibrinogen, haptoglobin and amyloid type A were measured before and after dietary changes. Serum fibrinogen, haptoglobin and amyloid A levels were significantly increased in horses of the second treatment group compared to horses in the first treatment group (p<0.05). There was also a statistically significant difference in the complete blood cell count due to the change of diet from forage to forage mixed with concentrate (p<0.05). It seems that changes in the natural flora of the horse's digestive tract following a change in diet can protect the animal's body against acute inflammatory and traumatic injuries.

153 - Evaluation of consumption of artificial sweetener Cipla on electrophoretic curve of serum proteins in diabetic male rats
Hamed Nasiri jafar rahmani kahnamoeiIntroduction: Sucralose is an artificial sweetener without calorie that derived from sugar or sucrose. It is 600 times sweeter than sugar also makes low calorie. Cipla as a commercial sweetener have different compounds such as, lactose, L-lusin, Cross Carmellose Sodium. MoreIntroduction: Sucralose is an artificial sweetener without calorie that derived from sugar or sucrose. It is 600 times sweeter than sugar also makes low calorie. Cipla as a commercial sweetener have different compounds such as, lactose, L-lusin, Cross Carmellose Sodium. Sucralose is stable in the presence of ethanol and can retain 99% of its true taste after one year, as well as maintain its properties during pasteurization, sterilization, and high temperature baking. It also does not interfere with glucose uptake, carbohydrate metabolism or insulin secretion. Pharmacokinetic studies have shown that 85% of sucralose is not absorbed and is completely excreted through the stool and its absorption rate is limited to 15% in passive release. Recent studies have shown a link between the use of sweeteners and renal toxicity, hepatotoxicity or retardation of fetal and placenta formation. Sucralose is converted to hydrolysis products 4- Chloro glucose and 1,6 di chlorofructose by hydrolysis. These metabolites are more resistant to hydrolysis and complete degradation as sucrose chlorination and conversion to sucralose alter the conversion of the molecule to glycosidic enzymes. The digestive tract, which normally breaks down carbohydrates, becomes. In a double-blind study by Grots et al., it was found that sucralose at a dose of 7.5 mg/ kg/day for one month had no significant effect on serum glucose and HbA1c levels in humans. Other studies on non-diabetic human specimens have shown that high doses of sucralose or aspartame do not affect blood glucose, peptide c, or hemoglobin levels of HbA1c, even at multiple doses. According to conflicting reports on the metabolic effects of sweeteners, the study assessed the effect of using the commercial form of sucralose (Cipla) on serum electrophoretic proteins in healthy and diabetic rats.Materials and methods: This study will be done on 24 male rats divided in four equal groups, control and treatment. Control group will have base ration. In the study of Shastry and et al, is 15mg/kg for human. Therefore, in this study dosage of sucralose will be 15mg/kg. Treatment group will be injected daily for 1-month. All rats used for this study have same peripheral conditions .At the end of the experimental period, all rat were bled, and after serum isolation, the serum protein electrophoresis curve was prepared and evaluated by acetate cellulose technique.Results and discussion:The amount of total protein and serum albumin was recorded in the healthy treatment group (7.18±0.22 g/dl) and (3.36±0.11 g/dl), in the diabetic control group (7.16±0.18 g/dl) and (3.41±0.09 g/dl), but with the amount of these factors in the serum of other study groups, there was no statistically significant difference (p>0.05). The amount of alpha 1 globulin in the serum of healthy control group (0.01±0.30 g/dl) was significantly lower than the rate of this factor in animal serum of diabetic control group (0.04±0.51 g/dl) and healthy treatment group (0.03±0.46 g/dl) (p 0.05). Gammaglobulin levels were determined in the healthy treatment group (1.20±0.12 g/dl), diabetic treatment (1.10±0.21 g/dl), healthy control group (1.33±0.14 g/dl) and diabetic control group (1.25±0.08 g/dl), Which showed a no significant statistical difference between the studied groups (p>0.05). The study showed that the use of aspartame, acesulfam, and sucralose sweeteners in acceptable daily intake (ADI) doses for three weeks did not have a mutagenic effect on healthy and diabetic rats and had no effect on serum factors which is consistent with the results of the present study. This study demonstrated a significant change in the alpha 1 globulin band in the electrophoretic curve. The bulk of this protein bond is made up of the alpha protein an antitrypsin, a single-chain glycoprotein consisting of 394 amino acids that has a molecular mass of about 52 kDa and easily passes through interstitial fluid to the target tissues. This protein has a negative charge and cannot pass through the glomerular membrane of the kidney. This protein is one of the most important inhibitors of serum human serum proteases and inhibits several proteins such as elastase, collagenase and trypsin. Diabeticization of the animals tested, as well as the consumption of sweeteners, appear to accelerate the production of acute phase proteins, increasing alpha 1 globulin in the electrophoretic curve.Conclusion: The results of this study showed no change in protein bands other than alpha 1 globulin. Therefore, it can be said that sucralose has little effect on the electrophoretic curve of serum proteins.Keywords: Cipla, Electrophoretic curve, Rat, Serum protein, Sucralose. Manuscript profile -

This experiment was performed to evaluate the effect of different levels of valine in low protein diets on the immune response of broiler chickens. This study was conducted using 200 one-day old male broilers of Ross 308 strain in a completely randomized design with 5 replicates and 10 birds per replicate. Experimental treatments were adjusted based on the Brazilian tables and included: control diet with recommended levels of valine, 10% higher than the recommended level of valine and 20% higher than the recommended level of valine diluted in a diet containing 2% protein. The results showed that different levels of valine had no significant effect on the weight of liver, spleen, fabricius bursa and leukocytes (p<0.05). Diets containing 20% valine significantly increased the HI antibody and humoral immunity responses (p<0.05). The initial total antibody response was not affected by the experimental treatments (p<0.05). But the level of 20% valine significantly increased the total secondary response and IgM secondary response to SRBC (p<0.05). Moreover the addition of valine had a significant effect on the injection reaction of PHA-P (p<0.05), and level of 20% valine, significantly increased the cellular immunity of broilers in comparison to the control treatment and lower valine levels. In the present study, the addition of high levels of valine in low-protein diets improved the cellular and humoral immunity of broiler chickens. Manuscript profile -

The disease can lead to significant economic losses in the livestock industry and may also be a threat for public health; because it may be transmitted to humans through consumption of milk and other contaminated animal products. Immunity and resistance against the Johne's disease is mainly due to cell mediated immune response. Heat Shock Protein 70 (HSP70) of this bacterium is one of its important proteins, which the immune response against it can prevent the fecal excretion of bacteria. In order to facilitate the production of recombinant vaccine against Johne's disease, in this study the recombinant HSP (recombinant HSP; rHSP) was produced and its immunogenicity investigated in rabbits. For this purpose, the hsp70 gene was cloned into pET-24a plasmid and the resulting recombinant plasmid was transferred to E. coli strain BL21. The expression of the above protein was checked by SDS-PAGE and the accuracy of the nucleotide sequence was confirmed by sequencing. Immunization of rabbits by rHSP70 resulted in the production of high levels of antibodies. Based on the findings, it seems that the HSP70 specific antibody can be evaluated in the design of diagnostic methods of the disease and the produced recombinant protein can be assessed for the production of recombinant vaccines.

Gout is recognized by deposition of urates in kidneys, on serous surfaces of the heart, liver, mesenteries, air sacs and peritoneum. In some cases, these deposits may be observed on surfaces of muscles, synovial sheaths of tendons and joints, too. These deposits are like chalky coating and appear grossly. Gout could be seen in two forms, articular gout and visceral gout, and it is a disease with numerous causes. The causing factors of the gout are classified in three groups which consist of nutrient and management factors, infectious factors, and toxic factors. For evaluation of biochemical parameters in gout disease, we surveyed and diagnosed in three farms of egg laying poultry breeding (HY-Line) affected to gout syndrome during spring and summer of 1386. In this study, from the above- mentioned poultry farms a number of 20 affected, and 20 healthy chickens (totally 120) were chosen and Blood samples of all animals were collected from wing veins and their sera were harvested by centrifuging and the levels of Uric acid, Total Protein, Albumin, Calcium and Phosphors parameters were measured by diagnostic laboratory kits. After taking blood, they were autopsied, and according to autopsy signs and syndromes, the diagnosis of gout was confirmed. Results of this study showed significant increase on mean serumic Uric acid, Total Protein, Albumin, Calcium and Phosphorus in chickens affected by gout in comparison with the healthy groups(p<0.05). In conclusion, with the measurement of these parameters in the laboratory, one could diagnose the gout syndrome even before the clinical signs become apparent. Manuscript profile -

In this study we evaluated the effect of different levels of yeast beta-glucan (YBG) on some blood parametrs of broiler chickens. In a factorial experiment based on completely randomized design (the first factor: YBG levels: 0, 0.04 and 0.08% of basal diet and sex as a second factor) 144 day old chicks (72 male and 72 female) were selected and allocated to different treatments (three replicates of each treatment). The overall experimental period was 34 days. At the end of study, two birds from each pen were randomly selected as a sample. The level of albumin, globulin, urea and total protein was measured on blood samples. Statistical analysis of the results showed that the YBG had no significant effect on albumin, globulin, urea and total protein level. But the amount of plasma albumin and total protein in female chicks was significantly higher than male chicks (p<0.05). The interaction effect of the two factors was not significant. Therefore, it can be concluded that the mentioned levels of yeast beta-glucan had no significant effect on the studied parameters. Manuscript profile -

Considering the need to know this physiological characteristic in different fields of cycling and introducing them to athletes interested in this field; The aim of present study was investigating and comparing the body composition of mountain range and non-elite road cyclists in Shiraz city.Methods: In this practical and semi-experimental study, 20 road cyclists and 20 mountain cyclists (age 18-24) were selected as a statistical sample. Protein mass, mineral mass, soft lean mass and body fat percentage of the subjects were evaluated using the BOCA X1 Body Composition device made in South Korea. Kalmogorov-Smirnov and Independent sample t tests were used to analyze the data. Findings: There was no significant difference in protein mass (P=0.21), mineral mass (P=0.23) and soft lean mass (P=0.96) in road and mountain cyclists; However, the percentage of body fat of road cyclists was significantly lower than road cyclists (P=0.013).Conclusion: It seems that the two types of cycling have the same effect on body composition, but road cyclists had a lower body fat percentage than mountain cyclists; Due to the limitations such as lack of assessment of diet, aerobic capacity and heart function, more studies are needed in this field.

Also, the combination of these interventions may have a synergistic effect on research variables. The present study investigates the independent and combined effect of aerobic exercise and curcumin supplementation on plasma C-reactive protein concentration in diabetic rats.Methods: Forty male rats were equally divided into healthy control, diabetic control, diabetic exercise, diabetic curcumin and diabetic curcumin + exercise. Aerobic exercise (five sessions / week, each session 30 minutes at a speed of 22 meters / minute, slope: five percent) and supplementation (30 mg / kg body weight, three days / week) were performed for eight weeks. Rats were sacrificed 48 hours after receiving the last intervention.Results: Diabetes increased the concentration of plasma C-reactive protein (P = 0.001). Exercise decreased plasma C-reactive protein concentration (P = 0.001) in diabetic rats. Curcumin also reduced plasma C-reactive protein (P = 0.001) in diabetic rats. The combination of exercise and supplementation had a greater effect on reducing the plasma C-reactive protein concentration than mono / supplementation alone (P <0.001).Conclusion: Exercise and curcumin separately reduced plasma C-reactive protein concentration in diabetic rats. It also seems that the use of a combination of exercise and curcumin than the use of each alone, has been more effective on the variables of the present study. Manuscript profile -

Research factors included mycorrhiza at three levels of control, Glomus intraradice, Glomus mossea, and also foliar application of humic acid at three levels of control, 15, and 30 mg/l. The experiment was conducted as pot and under normal and uncontrolled conditions. Measured traits included plant height, root length, number of plant pods, number of seeds in each pod, 100 seeds weight, seed protein, and nitrogen and phosphorus concentration of leaves. Application of mycorrhiza and humic acid increased measured traits except for the number of seeds in each pod and 100 seeds weight. There was no significant difference between the two strains and also levels of 15 and 30 mg/l humic acid in the studied traits. Generally, foliar application of 15 mg/l humic acid in the presence of mycorrhiza was more effective than other treatments. Manuscript profile -

The experiments were done in factorial form based on a completely random design with 3 repetitions. Treatments included three irrigation levels of normal (irrigation after 40% depletion of available soil moisture), average stress (irrigation after 60% depletion of available soil moisture), and severe stress (irrigation after 70% depletion of available soil moisture) as the main factor and levels of methanol in the form of foliar application including control solutions (foliar application without use of methanol) and solutions of 14.7% and 21% of methanol as secondary factor. Results obtained from the study showed that there were significant differences between various levels of methanol in content of chlorophyll and carotenoid compounds, relative water content, phenolic compounds, total protein content, proline, and leaf peroxide hydrogen in (P≤0.01). With the application of stress from mild to severe, application of 14% methanol showed more pronounced effects on total chlorophyll content, chlorophyll a and chlorophyll b. Moreover, under mild and severe stress conditions, with application of the highest value of methanol, production of peroxide hydrogen reached lowest level and the content of phenolic compounds increased with the increased application of methanol from 7% to 14%. According to the obtained results, with application of 14% methanol, more increase was observed in the efficiency of proline under severe stress conditions. Increasing the volume of methanol from 7 to 14%, the relative water content was preserved under stress conditions. For protein, with increased drought stress, the effect of application of 14% methanol was the same in comparison with 21% methanol. Therefore, according to the obtained results, it is concluded that methanol could improve plant resistance against drought stress. Manuscript profile -

After collecting aerial parts of L. Serriola from the farms in Vamenan village in Azadshar, various organs such as root, stem, and leaf were dried and powdered separately. Also, mixed organs were considered as another treatment for comparison. Then various organs of L. serriola and a mixture of them were analyzed qualitatively for primary metabolites like organic matter, raw ash, protein, proline, starch and soluble sugar as well as membrane stability index and some secondary metabolites like total phenols and anthocyanin. Results showed that various organs of L. serriola had a various content of primary and secondary metabolites as well membrane stability index. On the basis of the findings, the highest and lowest contents of organic matter and raw ash were obtained in leaf, respectively. The highest content of protein, starch and compatibility osmotic of soluble sugar and proline also were found in the leaf organ. The highest content of total phenols and anthocyanin were obtained in leaf showing a positive and significant correlation with membrane stability index. Regarding the high biomass generated from L. serriola, it is suggested to analyze the other chemical compounds in this plant. Complimentary studies are required to exploit the application of these compounds as bio herbicide. Manuscript profile -

Tarom Hashemi), a field experiment was carried out as factorial based on randomized complete block design with 16 treatments and three replications in Nour in 2016. The experimental treatments included T1: Control, T2: Calcium silicate soil application, T3: Zinc sulfate soil application, T4: Calcium silicate + Zinc sulfate, T5: Nano-Si foliar application, T6: Nano-Si + Calcium silicate, T7: Nano-Si + Zinc sulfate, T8: Nano-Si + Calcium silicate + Zinc sulfate, T9: Nano-Zn oxide foliar application, T10: Nano-Zn oxide + Calcium silicate, T11: Nano-Zn oxide + Zinc sulfate, T12: Nano-Zn oxide + Calcium silicate + Zinc sulfate, T13: Nano-Si + Nano-Zn oxide, T14: Nano-Si + Nano-Zn oxide + Calcium silicate, T15: Nano-Si + Nano-Zn oxide + Zinc sulfate and T16: Nano-Si + Nano-Zn oxide + Calcium silicate + Zinc sulfate. Results showed that straw protein, zinc and silicon in grain and straw were affected by experimental treatments, but the evaluated treatments showed no significant effect on grain protein and chlorophyll content of flag leaf. Among evaluated treatments, the combined application of silicon and zinc improved nutrient absorption compared to separate application of each element and control. This indicates the aggregation of Zn and Si compounds and their synergistic effects. Combined application of silicon and zinc by both methods of NP foliar application and soil application (T16) improved nutrients uptake in grain and straw of rice, but among the methods used, the NP foliar application had a more positive effects in improving physiological characteristics of rice plants than the treatments of soil application of elements.

Experimental factors were three levels of nitrogen in recommended amount, 15 and 30 percent more than the recommended amount (125, 143.75, and 162.5 kgN.ha-1, respectively) and plant density at two levels, namely 350 and 420 plants per square meter which were the main plots and seed quality at four levels including control, 15, 30, and 45 hours of accelerated aging was subplots. Grain yield, protein and starch performance were significant under the triple effects of seed quality, planting density, and nitrogen fertilizer. With increasing levels of seed aging significant reduction were observed in all traits (except grain protein and nitrogen percentage). Application of nitrogen fertilizer 30 percent more than the recommended dose, as well as plant density of 420 plants per square meter significantly increased grain protein and nitrogen percentage. The highest average protein yield was achieved in the combined treatment of 350 plant square meters at 30-hour aging level and nitrogen fertilizer at 15 percent more than the recommended dose and also in combined treatment of 420 plant square meters, 45-hour aging level, and the nitrogen level 30 percent more than the recommended dose. Generally, seed deterioration reduced its quantitative and qualitative characteristics but more nitrogen fertilizer improved quality traits, thereby improving the quality loss. Manuscript profile -

Since plants facing different environmental conditions cannot move, they are forced to cope with difficult conditions and withstand a series of physiological and morphological changes. This study was done to investigate the effects of air pollution on some physiological indices of P. kansuensis plant. These indicators included chlorophyll pigments, carotenoids, anthocyanins, and protein content. The results showed that chlorophyll a, chlorophyll b, carotenoids, and proteins in the contaminated area as compared with the clean area increased significantly. But anthocyanin content in the clean area did not change significantly compared to the contaminated area. Also, analysis of catalase and superoxide dismutase activities in the polluted regions showed a significant increase in comparison with the clean regions. Therefore, air pollution in Tehran can have adverse effects on photosynthetic efficiency of plants and air purification. functions of the plants which are one of the goals of the green spaces in major cities in addition to the beauty of urban space.

Two levels of irrigation involving control (full irrigated under water farming conditions) and drought stress (irrigation cut after anthesis until the end of growth period) as the first factor and different wheat genotypes (TEVEE'S'//CROW/VEE'S and Shark: drought sensitive, Manning/Sdv1/Dogu8 and Sabalan: semi tolerant, Sardari HR-86 and Dogu88/Ghafghaz 7: tolerant to drought stress) as the second factor were considered and agronomic and physiological characters were measured. Drought stress decreased grain yield through decreasing 1000 grains weight. Manning/Sdv1/Dogu8 semi tolerant genotype showed the highest and Shark genotype showed the lowest grain yields. Results showed that soluble protein content increased in flag leaves and spicules under stress compared to control. Sardari HR-86 and Shark genotypes showed the highest and lowest soluble protein content in flag leaves, respectively. The highest and lowest soluble protein contents in spicules were observed in Manning/Sdv1/Dogu8 and Shark genotypes, respectively. The study also showed that peroxidase, ascorbate peroxidase, and superoxide dismutase enzymes activities increased under drought. The highest enzyme activity was observed in flag leaves of Sardari HR-86 tolerant genotype and in spicules of Manning/Sdv1/Dogu8 semi tolerant genotype in the last step of sampling. Also, sensitive genotypes showed the lowest enzyme activities. Based on the obtained results it seems that in Manning/Sdv1/Dogu8 semi tolerant genotype, activation defense system of peroxidase and superoxide dismutase enzymes had a key role in improving tolerance to drought stress.

The experiment consisted of 13 treatments including NPK, biophosphorus, biophosphorus + 25% NPK, biophosphorus + 50% NPK, biophosphorus + 100% NPK, nitroxin, nitroxin + 25% NPK, nitroxin + 50% NPK, nitroxin + 100% NPK, biophosphorus + nitroxin, biophosphorus + nitroxin + 25% NPK, biophosphorus + nitroxin + 50%NPK and biophosphorus + nitroxin + 100%NPK. The results showed that the effect of different treatments of chemical, biological, and integrated fertilizers were significant on most of the studied traits except the number of leaves, flowering date, and the number of florets per head. The highest mean in most of the studied traits belonged to the nitroxin + biophosphorus + 100% NPK treatment which was not significantly different from the nitroxin + biophosphorus + 50% NPK integrated treatment. The results of this study showed that combined application of nitroxin + biophosphorus + 50% NPK in comparison with the integrated treatment of nitroxin + biophosphorus + 100% NPK in addition to reducing 50% of chemical fertilizers application can also produce optimal yield. According to the obtained results, the application of 50% of the recommended amount of chemical fertilizers in combination with the nitroxin and biophosphorus biofertilizers can be recommended for obtaining the maximum quality and quantity yield of sunflower.

Treatments included chlormequat chloride concentrations (0, 500, 1,000, and 1500 mg/ha) and nitrogen at 3 levels (50, 100, and 150 kg/ha). Results suggest a significant difference between interaction effects of chlormequat chloride and nitrogen fertilizer on chlorophyll content, relative water content, yield and protein percentage, and activity of superoxide dismutase and catalase enzymes at 1% probability level and in the number of seeds per spike, 1000 seed weight, and glutathione peroxidase enzyme activity at 5% probability level. An increase in the consumption of nitrogen fertilizer decreased the relative water content of leaves due to reduced leaf water potential. Chlormequat chloride by transferring sufficient photosynthetic material to the seeds played an important role in their filling and increased seed weight. Also, the activities of superoxide dismutase, catalase, and glutathione peroxidase enzymes were decreased by increasing the consumption of chlormequat chloride concentration and nitrogen uptake. In general, through applying 1500 mg/ha chlormequat chloride and 150 kg/ha nitrogen, the highest chlorophyll content, relative water content, yield components, yield, and protein percent were obtained.

In this study, split plots were used in a randomized complete block design with three replications. The treatments consisted of different amounts of sugarcane compost at three levels of 0, 15, and 30 ton/ha as main plots and nitrogen fertilizer from urea source at three levels of 80, 160, and 240 kg/ha nitrogen as sub plots. Results showed that the effect of sugarcane compost and nitrogen on number of rows per ear, number of seeds per ear, 1000 grain weight, grain yield, and protein yield were significant but the effect of interaction between treatments on all traits were not significant. The maximum grain yield and protein yield were obtaied under 30 ton/ha sugar cane compost and 240 kg/ha nitrogen and the minimum grain yield and protein yield were in non-consuming sugarcane compost and 80 kg/ha nitrogen. In general, the results of experiment showed that increasing the application of sugarcane compost and nitrogen up to 30 ton/ha and 240 kg/ha, had a significant effect on quantitative and qualitative yield of corn and can be considered by farmers and researchers.

This research was performed as a factorial completely randomized design with four replications under greenhouse conditions. Sunflower plants were exposed to cadmium chloride treatment (0, 50, 100, 150 and 200 µM) at two-leaf stage on a weekly basis. One week after cadmium treatment, plant leaves were sprayed with salicylic acid (0, 250 and 500 µM). After harvesting the plants, cadmium concentrations in roots and shoots were measured. Then, antioxidant enzymes were assayed. Total protein content of leaf samples was extracted and the pattern of leaf protein changes was investigated by SDS-PAGE electrophoresis. Cadmium concentration in roots and shoots increased with increasing cadmium and salicylic acid treatment. Catalase enzyme activity decreased with increasing cadmium concentration, and salicylic acid had a very small effect on its activity. The activity of superoxide dismutase, ascorbate peroxidase, and glutathione reductase enzymes increased with increasing cadmium concentration while increasing salicylic acid concentration reduced the activity of these enzymes. Leaf protein electrophoresis under cadmium and salicylic acid treatments showed differences in leaf protein intensity compared with control plants. The expression of some proteins was increased or decreased in the treated plants. Therefore, cadmium and salicylic acid treatments made changes in the amount of cadmium uptake, antioxidant enzymes activity, and the pattern of sunflower leaf proteins. Manuscript profile -

The main treatment included drought stress at three levels of control (irrigation based on 100% water requirement of corn), mild stress (based on 85% of the plant's water requirement), and severe stress (based on 70% of the plant's water requirement). The second treatment included spraying with distilled water as control, abscisic acid (100 mM), gibberellin (100 ppm), salicylic acid (5 mM), and Nano-zinc (2 gl-1 water). The results of this experiment showed that the effect of year on biological yield, crude protein, and forage yield were significant. Also, the effect of drought stress and spraying on leaf area index, chlorophyll index, biological yield, crude protein, and forage yield were significant. Also, the effect of drought stress and spraying on leaf area index, chlorophyll index, biological yield, crude protein and forage yield were significant. The highest forage yield (90.44 t ha-1) was obtained under the complete irrigation with salicylic acid treatment. Salicylic acid treatment resulted in higher forage yield under the complete irrigation conditions. Salicylic acid treatment also reduced the damage of mild and severe stress treatments by 27 and 9%, respectively. According to the results of the experiment and CGR, using salicylic acid treatment during three foliar application periods at eight-leaf, before tassel emergence, and at the milky stage was able to reduce drought stress and is recommended for conditions similar to the present experiment.

Having a diversity of climates, Iran has a great variety of medicinal plants. Detecting the growth status of medicinal plants under drought stress conditions can lead to the cultivation of resistant plants in dry or semidry areas. In the present study, we investigated the morphological and physiological responses of ten ecotypes of the medicinal plant Teucrium polium L. native to southeastern Iran under drought stress. For this purpose, a factorial greenhouse experiment was conducted in a completely randomized design with three replications. In this experiment, moisture treatments of 100, 70, and 40% of field capacity were applied. Analysis of the data showed that the morphological traits under study including stem length and fresh and dry weight of shoots decreased by 5% with increasing drought stress. Drought stress also increased root length, proline content, and phenolic compounds while decreasing chlorophyll a, b, total chlorophyll, and protein contents. The highest resistance to stress was shown by ecotypes growing in Sarcheshmeh and Kuhpayeh regions and the lowest resistance was shown by plants in Shahdad and Anbarabad regions. The results of the study indicated the relative resistance of this plant to drought stress. Therefore, it is a very suitable medicinal plant for cultivation in dry and low water areas of Iran. Among the studied ecotypes, the plants of Sarcheshmeh and Kuhpayeh regions responded 40% better to drought stress conditions and cultivation of these ecotypes in stressed areas can be recommended with more confidence.

No information is yet available on the effect of humic acid and plant density on paddy yield and some of its biochemical traits. For this purpose, an experiment was conducted in a research farm located in Gonbad city during May to September 2019 in the form of split plot-factorial based on randomized complete block design with three replications. Plant density (plant spacing per row) was considered as the main factor with 4 levels (5, 10, 15, and 20 cm) and humic acid consumption at 2 levels (humic acid consumption, no humic acid consumption) was considered as subplots. Humic acid fertilizer with a concentration of 250 ml per hectare was added in three stages including tillering (4-6 leaves), stalking (20-30 days after tillering), and before panicle initiation. Results showed that the effects of plant spacing on row and humic acid application on 1000-seed weight, paddy yield, biological yield, harvest index, grain protein, water use efficiency, and chlorophyll a and b and total chlorophyll were significant. Considering 5 and 10 cm plant spacing on rows along with humic acid application had the highest rice yield and water use efficiency. Also, chlorophyll content showed a significant change with increasing plant density and application of humic acid with a significant increase in chlorophyll a and b, which in turn was effective in increasing paddy yield. Rice protein also showed the highest level in 10 cm spacing between plants on each row along with the application of humic acid. Manuscript profile -

Plants were cultivated under 10 NPK treatments with sulfur fertilizers (granular or bentonite, with or without thiobacillus and ammonium sulfate each in two concentrations) and one NPK treatment without sulfur, compared with the control in randomized complete blocks for 4 months. Growth parameters including dry and fresh weight of plants, roots, shoots and the ratio of fresh or dry weight of roots to plants as well as protein, chlorophyll, potassium, phosphorus and sulfur content in roots or shoots were measured. NPK fertilizer did not increase phosphorus and potassium uptake but decreased root growth. Addition of sulfur fertilizers except for bentonite sulfur with a concentration of 0.8 g per 80 cm2 of soil with Thiobacillus commercial liquid fertilizer, 250 ml / l, had no effect on recovering the negative effects of NPK and even in most treatments, shoot dry weight and fresh weight decreased. Ammonium sulfate showed the most negative effect on growth parameters. Also, some sulfur treatments had a positive effect on increasing the amount of shoot protein. Chlorophyll a, b and total levels did not show a significant difference between treatments. The effect of sulfur fertilizer on soil pH was different and higher concentration of granular sulfur fertilizer containing Thiobacillus caused a more severe drop. None of the sulfur treatments increased the phosphorus of the shoot and even some treatments had a negative effect on the phosphorus content of the roots as well as the potassium content of the roots and shoots. Only in the treatment of granular sulfur fertilizer with Thiobacillus at lower concentrations, root potassium content increased. Negative effects of sulfur fertilizers were not due to increased sulfur uptake, because the sulfur content changes between treatments were not significantly different. Manuscript profile -

Treatments included foliar application of nano Fe and Zn oxides at four levels (foliar application with water as control, foliar application of nano iron oxide (0.6 gL-1), nano zinc oxide (0.6 gL-1), combined foliar application of nano Fe and Zn oxides (0.3 g L-1 each), and application of mycorrhiza at four levels (no application of mycorrhiza as control, application of Mycorrhizae mosseae, Mycorrhiza intraradices, and combined application of Mycorrhiza intraradices with mycorrhiza mosseae). Means comparison showed that foliar application of nano Fe-Zn oxides as well as combined application of mycorrhizal mosseae and intraradices increased number of active nodules per plant, percentage of active nodules per plant, 100 grain weight, and grain yield by 173.2, 93.08, 36.58, and 58.34% respectively in comparison with no foliar application of nano Fe-Zn oxide and no application of mycorrhiza. Also, combined foliar application of nano Fe-Zn oxide along with mycorrhiza mosseae and intraradices increased respectively the number of grains per pod, number of pods per plant, dry weight of root, zinc content of grains, and protein contentof grains increased by 42.14, 95.17, 12o, 58.2, and 47.55%, respectively in comparison with no application of mycorrhiza and nano Fe-Zn oxide. It seems that foliar application of nano Fe-Zn oxide and mycorrhiza application owing to improving some morphophysiological traits can be considered as a proper method for increasing quantitative and qualitative yield and mitigating the effects of water deficit in rain fed conditions.

In order to investigate the effect of different levels of sulfur fertilizer (S) and foliar application of zinc (Zn) on the yield and concentration of oil and protein, a factorial experiment was conducted in a randomized complete block design with three replications for two year (2019 and 2020) at Astana-Ashrafieh city, Gilan province. The studied factors were included S fertilizer (from gypsum source) at four levels (0, 20, 40 and 60 kg ha-1) and Zn fertilizer (from zinc chelate source) at three levels (0, 1000 and 2000 ppm). The results showed that the interaction of S and Zn fertilizers had a significant effect on pod yield, grain yield, number of grains and pods, protein and oil concentration. Mean comparison of the studied traits also showed the highest pod yield (156 g plant-1) in the treatment of 40 kg S + 1000 ppm Zn, while the highest grain yield (92.3 g plant-1) in the treatment of 60 kg S + 2000 ppm Zn was obtained. The highest weight of 100 grains (1283.6 g) belonged to the treatment of non-using of S + 1000 ppm Zn. The highest protein concentration (17.94%) was observed from treatment of non-using of S + 2000 ppm Zn, and oil concentration (46.09%) in sulfur fertilizer treatment of 60 kg S + 1000 ppm Zn. Based on the results of this experiment, it can be stated that the simultaneous application of sulfur fertilizer and zinc foliar application significantly increases grain yield and improves yield-related traits in the peanut and it can be recommended for the climatic conditions of Gilan.

The main factor of soil salinity (2 and 10 dS/m), sub-factor of planting date (6 November, 21 November, 6 December, 21 December, and 5 January), and sub sub-factor of plant density at three levels (208000, 277000, and 416000 plants per hectare) were considered. Results showed the interactions of environment × planting date on all studied traits including fresh weight, dry weight, percentage of leaf protein, percentage of stem protein, percentage of pod protein, percentage of total protein, protein yield, percentage of leaf fibers, percentage of stem fibers, percentage of pod fibers, percentage of total fibers, fiber yield, and leaf proline concentration were significant. The interaction effect of environment × planting density was also significant on all characteristics under study except for leaf protein percentage and leaf proline concentration. Moreover, the interaction effect of planting date and planting density was significant on all characteristics under study except for stem protein percentage and leaf proline concentration. Generally, it is concluded that the cultivation of forage mustard on November 6 and with planting density of 208,000 plants per hectare produces the highest fresh and dry weight of forage and protein yield, as well as the lowest amount of fiber.

Experimental fact MoreA factorial experiment was conducted on Triticosecale Wittma L. based on a randomized complete block design with three replications in Research Greenhouse of the Faculty of Agriculture and Natural Resources, University of Mohaghegh Ardabil during 2020. Experimental factors included salinity levels (non-application of salinity as control and soil salinity of 50 and 100 mM NaCl), and bio-fertilizers (no application of bio-fertilizers as control, application of vermicompost, flavobacterium, vermicompost + flavobacterium + humic acid (foliar application with water as control and foliar application of 2 g.L-1 humic acid). Results showed that the highest leaf area index, root weight and volume, and leaf protein content were recorded in combined applications of vermicompost + flavobacterium + foliar application of humic acid under non-salinity conditions. Also, combined application of vermicompost + flavobacterium + foliar humic acid under non-salinity conditions decreased dry matter translocation from stem, shoot, and its contribution to grain yield by 31.97, 40.8, and 138.84% respectively while increasing grain yield, current photosynthesis, and contribution of current photosynthesis in grain yield by 69.56, 151.44, and 48.3%, respectively compared to no application of bio-fertilizers and humic acid under 100 mM soil salinity. Based on the results, it seems that the application of bio-fertilizers and humic acid can increase current photosynthesis and its contribution in grain yield of triticale by improving leaf area index, root weight, and volume.

The main treatment included water stress with three levels control (without water stress), water stress in female flower formation stage and water stress in grain swelling stage. Also, foliar application of cycocel at three levels of control (no use of cycocel), 442.5 ppm, and 885 ppm and three levels of micronutrient fertilizers, namely control (no fertilizer application), foliar application of 1000 g. ha-1, and foliar application of 1500 g. ha-1 were considered as the sub-factors. Results of the combined ANOVA showed that the interaction of the effects of year, stress, micronutrient, and cycocel on relative water content, proline and grain yield and also the interaction of the effects of stress, micronutrient, and cycocel on hydrogen peroxide, glutathione peroxidase, and soluble proteins were statistically significant (p≤0.01). The results also showed that the highest activity of superoxide dismutase enzyme was obtained under stress conditions at the grain swelling stage, which showed an increase by about 37% compared to the irrigation treatment under optimal conditions. Foliar application of 1500 g. ha-1 micronutrient and 885 ppm cycocel in non-stress conditions increased the average grain yield (11500 kg. ha-1) in the second year by about 85% compared to stressed condition at grain swelling stage and no application of micronutrient and cycocel. In general, to increase grain yield under optimal irrigation conditions and reduce the drop in stress conditions, growth regulators such as cycocel with a concentration of 885 ppm and micronutrient foliar application at 1500 g. ha-1 are recommended.

Treatments included salinity stress at two levels (0 and 100 mM NaCl) and potassium silicate solution at two levels (0 and 5 mM). The physiological and biochemical traits of Camelina sativa under salinity stress were evaluated along with the role of osmotic substances such as soluble sugar and soluble protein in reducing the harmful effects of salinity stress. Results showed that salinity stress significantly reduced the amount of chlorophyll a, b, and total in Camelina sativa, while silica treatment significantly reduced the harmful effects of salinity. Soluble sugar content of leaves in response to salinity stress was 46% lower than in the control plant. Salinity stress combined with silica increased the amount of soluble sugar 27% more than the control plant. Results also showed that in the treatment with silica under 100 mM salinity level, the amount of leaf proteins was almost 10% less than the control plants. The results of measuring the plant’s antioxidant capacity of FRAP showed that in response to silica treatment without salinity, no significant difference was observed in the amount of antioxidant capacity of FRAP, while in the combined treatment of salinity stress + silica it decreased by 9% compared with the control plants. The results of this study supports the beneficial role of silica as an environmentally friendly compound to increase plant resistance to salinity stress. Manuscript profile -

Before NaCl and CaCl2 treatments and after vegetative generation, ascorbate was treated in two concentrations of 2.5 and 5 mmol. CaCl2 treatments supplemented as 25 and 50 percent of salt treatment. Results indicated that with increasing of salinity (EC), calcium and ascorbate treatments, Na+, Cl-, Ca+2 and K+ of leaves increased significantly, in comparison with control. CaCl2 and ascorbate treatments have no diminishing effects on salinity stress intensity and Na+ absorption. Plant did not use soluble sugar and proline as an osmolyte for increasing osmotic pressure. Glycine betaine and total protein contents increased with increasing of salinity stress and plant got included among plants with the strategy of production and accumulation of glycine betaine and did not use proline. Suitable need of calcium for amelioration of peroxidase activity for scavenging of reactive oxygen species was different in salinities. Calcium oxalate and raphide morphology and raphide bundles number in cross section of leaves and raphides needles number in volume unit had no specific physiological trend and did not change significantly and was not affected by soil salinity, calcium concentration and ascorbate treatments.

JAH 109, isolated from rice field, were evaluated in combination of limited irradiance (2 uE.m-2.s-1), different pHs (5,7,9) and inorganic carbon availability. Nostoc sp. JAH 109, can be considered as an alkalophilic organism. Optimal growth rate were observed at pH 9. Size of phycobilisomes and relationship between photosystem II and photosystem I increased in pH 9 and DIC available condition. This strain could not grow well in acidic condition, but neutral and alkaline condition cause active carbon dioxide concentration mechanism system. The pattern of nitrogenase activity seems more or less regular and linear at the first days after inoculation both in neutral and alkaline conditions. With respect to nitrogenase activity, the highest rate was in pH 9 and DIC availability. This seems true for heterocyst frequency fluctuations too. The higher photosynthetic capacity (Pmax) per unit of chlorophyll was resulted in higher DIC concentration at alkaline condition. Manuscript profile -

The cells MorePseudomonas aeruginosa is the main cause of nosocomial infections, and is resistant to most antibiotics, this study aimed to evaluate the effects of different stress conditions on growth, the protein profile, and biochemical characteristics of this bacterium. The cells of P. aeruginosa ATCC 27853 in the logarithmic phase were exposed to different stress factors such as sucrose concentration, ethanol, acid, osmotic pressure, and CoCl2. Following each stress condition, the growth and the survival of bacterial cells were determined. Microscopic observation showed morphological changes in different stress conditions. P. aeruginosa ATCC 27853 tolerated up to pH 3, 55% (V/V) ethanol, and CoCl2 up to 7% (W/V), and beyond these amounts, the bacterium lost its ability to survive. Maximum tolerance to sucrose was about 35% (W/V). The results showed that different stress conditions could not effect on the main biochemical characteristics of P. aeruginosa ATCC 27853. Scanning electron microscopy of the cells exposed to different stress conditions showed wide changes in the morphology of cells. In addition, upon treatment of different stresses, significant changes were observed in the protein profile of P. aeruginosa ATCC 27853 according to SDS-PAGE analysis. It can be concluded that severe environmental stresses have great effects on the growth pattern, phenotypic characteristics, and protein profile of P. aeruginosa ATCC 27853. If the stresses are induced all at once, they will cause death, but if they are affected slowly and for a longer period, most bacteria will be able to repair the damaged parts, and the growth of will resume.

Mung bean sprouts are one of the most commonly used bean sprouts and considered an as appropriate source for the extraction of highly valuable proteins.Experimental: In this study, the effect of different solid to solvent ratios (1:5, 1:10, 1:15 and 1:20 g/mL in electrohydrodynamic (EHD)-assisted extraction on the extraction yield and functional characteristics of sprouted mung bean protein isolate (SMPI) was evaluated. In addition, the structural and thermal properties of SMPI were investigated using Fourier transform infrared spectroscopy (FTIR), and differential scanning calorimetry (DSC), respectively.Results: The highest protein extraction yield, protein solubility (PS), oil absorption capacity (OAC), foaming capacity (FC) and foaming stability (FS) were obtained in the solid to solvent ratio of 1:20 g/mL. The results of FTIR showed that in the solid to solvent ratio of 1:20, the α-helix structure in SMPI decreased and transformed to random coil structure, leading to increased protein solubility. According to the DSC analysis, the highest denaturation temperature and protein stability were attributed to the solid-to-solvent ratio of 1:20 due to higher water content.Recommended applications/industries: The present results indicated that EHD pretreatment with the solid to solvent ratio of 1:20 could improve the functional properties of SMPI and EHD-assisted extracted SMPI could be considered as a potential nutraceutical or ingredient of functional and health-promoting foods.

258 - The Effect of Mycorrhiza and Humic Acid Application on the Quantitative and Qualitative Yield of Red Bean, Derakhshan Cultivar
Ali Asghar Goharivahid Mojtaba Yousefirada factorial pot experiment was conducted in the form of a complete random block design with three repetitions under greenhouse condition. The first factor of the study was mycorrhiza at three levels, namely control (no mycorrhiza), Glomus intraradices strain, and Glomus Morea factorial pot experiment was conducted in the form of a complete random block design with three repetitions under greenhouse condition. The first factor of the study was mycorrhiza at three levels, namely control (no mycorrhiza), Glomus intraradices strain, and Glomus mosseae strain. The second factor of the study included three levels of humic acid, namely 0 (control), 15, and 30 mg L-1. The results showed that with the application of mycorrhiza and humic acid, the number of seeds per plant, seed weight per plant, chlorophyll index, percentage of seed protein content, and nitrogen, phosphorus, and potassium contents of leaves increased. The highest seed weight per plant (13.47 g) was recorded in the red beans treated with 30 mg L-1 of humic acid + Glomus intraradices strain and 13.01 g and 13.72 g in the plants treated with 15 and 30 mg L-1 of humic acid, respectively along with Glomus mosseae strain. Also, the highest percentage of seed protein was 26.15% obtained from the treatment with 30 mg L-1 of humic acid + Glomus intraradices and 25.23% and 27.93% in the treatments with 15 mg L-1 and 30 mg L-1 of humic acid, respectively along with Glomus mosseae. Maximum leaf nitrogen content (5.85%) was obtained from the application of 30 mg L-1 of humic acid with Glomus mosseae.

This study revealed that the increase of Cd concentration in understudy treatments causes the 49% reduction of sugar solution in 10 mm treatment. On the other hand, the gradual increase of Cd in cultivation caused the increase of starch, reduction of photosynthesis and blockage of carbon cycle enzymes. Furthermore, in heavy metal stress conditions of vegetative stage, Cd has negative effects on the protein amount of total treatments in p=0.01 signified level. When treatment starts, the amount of protein reduced until 33% in 0.1 mm concentration and this reduction can be seen also in other treatments. In contrast, in flowering stage the amount of protein is increased compared to the control. The study of different heavy metal concentration effects showed that plants are more sensitive to Cd (2-20 times more than others). The Generalized Linear Model variance test of aerial and underground plant organs traced the high level of Cd concentration in root in10 mm concentration. This increasing process in p=0.001 level also was seen in root, leaf, and fruit. The accumulation of Cd expressed high speed of Cd transport from the soil to upper organs of tomato, and this process reduced the amount of solvable sugar and protein. Manuscript profile -

This stage requires the activation of a set of genes in apical meristem, the expression of which transforms the meristem from vegetative to reproductive. The APETALA1 (AP1) gene plays an important role in transition phase and flower meristem identity. The identification and homology of this gene and its deduced protein in Eruca sativa was studied. Total RNA was extracted from flower buds and cDNA made. Specific primers were designed and then used for RT-PCR reaction. The results showed that the desired fragment of the gene contains 782 nucleotides (complete cds). This fragment was called EvsAP1 and recorded in the NCBI database (KX524132.1). BLAST of this sequence with other species, showed that Raphanus sativus and Brassica nigra have the highest similarity (87%) with EvsAP1. The deduced protein of the EvsAP1 gene contains 256 amino acids, which is 82% similar to Raphanus sativus. The total length of AP1 protein obtained from NCBI databases in most species of Brassicace is 256 amino acids confirming the sequence. Examination of location of the different species in the phylogenetic tree showed that all species of Brassicaceae place in clads close to Eruca sativa. The species has the highest similarity with Brassica nigra and Raphanus sativus so that the later and Eruca sativa located in one clade. These results confirm the accuracy of the obtained sequence for the AP1 gene in this specie. Manuscript profile -

Although a wealth of in vitro and in vivo evidence indicates some common inhibitory activity of these compounds, they don’t generally suggest the same mechanism of action. In the present study, using a range of techniques including Thioflavin T and Nile red fluorescence assays, Congo red absorbance measurements, and atomic force microscopy the ability of taxifolin on the inhibition of HEWL amyloid fibrillation was investigated. Obtained results demonstrated that taxifolin exerts its inhibitory effect by binding to HEWL prefibrillar species. Furthermore, it’s binding results in diverting the amyloid pathway toward formation of very large globular, chain-like aggregates with low β-sheet content and reduced solvent-exposed hydrophobic patches. ThT fluorescence measurements show that the binding capacity of taxifolin is significantly reduced, upon generation of large protofibrillar aggregates at the end of growth phase. We believe these results may help design promising inhibitors of protein aggregation for amyloid-related diseases. Manuscript profile -

However, the mechanisms by which these natural molecules modulate the protein aggregation process are poorly understood. Silybum Marianum is one of the medicinal plants with a wide range of health benefits. Silymarin, extract of the seeds of Silybum Marianum, contains a mixture of flavonolignans and a flavonoid. In the present study, using a range of techniques including Thioflavin T and Nile red fluorescence assays, Congo red binding assay, Circular Dichroism spectroscopy, and Atomic Force Microscopy the efficacy of Silymarin on the inhibition of Hen Egg White Lysozyme (HEWL) fibril formation was investigated. Obtained results demonstrated that Silymarin effectively inhibits fibrillogenesis of HEWL in a concentration-dependent manner. AFM images indicated typical fibrillation in the control solutions, while in samples incubated in the presence of Silymarin extensive inhibition of HEWL fibrillation and amorphous aggregates formation was observed. Based on obtained results, we suggest that preventing of hydrophobic interactions between HEWL amyloidogenic prefibrillar species is the mechanism by which Silymarin inhibits amyloid fibril formation by HEWL. However, additional studies are needed to elucidate the detailed mechanisms involved. Manuscript profile -

The results for both complexes were almost identical, as fluorescence spectroscopy showed that the inherent fluorescence quenching of both proteins is due to the interaction of the zinc complex through a static quenching mechanism. The zinc complex interacted with both proteins with almost the same affinity. Thermodynamic parameters showed the contribution of hydrogen bonding and van der Waals interactions, but the role of hydrophobic interactions is not insignificant due to the presence of the imine group in the complex structure and the small amount of ∆S. Structural changes during the interaction of zinc complex with two proteins were investigated by synchronous‎ fluorescence methods as well as circular dichroism. The results of synchronous‎ ‎ fluorescence showed that during the interaction of the complex with proteins no noticeable polarity change occurred around the tryptophan residue while around the tyrosine residue the polarity changed. The study of circular dichroism spectroscopy also shows a decrease in the content of the alpha helix in both complexes. The results of this study confirm that the interaction of the zinc complex in both proteins is almost similar, so sometimes in pharmacological studies it can be used instead of human protein from its animal family.

In this work, a comparative study on the effect of the natural rubber protein content that was obtained by two Kjeldahl and Fourier transform infrared spectroscopy methods considered on the tensile properties of rubber compounds and second order correlation models were obtained. These models were used to predict the tensile properties of natural rubber based compounds. The results showed that the Fourier transform infrared spectroscopy method is more successful for prediction of the properties. Tensile strength and modulus 100% were predicted by less than 10% error, elongation at break and modulus 300% were also estimated by less than 25% error. This new approach makes it possible to predict the tensile properties of rubber compounds before preparing,, by consuming a small amount of natural rubber and using a fast and non destructive technique.

An increasing interest in fish food consumption because of its health benefits has made seafood products to play an essential role in food basket of Iranian family as like as other parts around the world. Aquaculture growth in Iran and throughout the world has provided a suitable condition to supply nutrition safety for this valuable food source. Now, from a total amount of 78.4 g daily dietary protein intake per capita, 30.7 g is supplied by animal protein from which 5 g is comprised of fish protein. Results obtained during the last half a century indicates that fish consumption growth in Iran has been far more than other parts in the world; however, its consumption rate per capita is much lower. It is noteworthy that fish food consumption growth was higher rather than chicken and red meat consumption growth according to the base year 1965, as Fish per capita consumption can be elevated by different accessibility methods and controlling price and quality.

This study was aimed to evaluate the production of Aspergillus niger single cell protein and simulation of cell biomass production based on several un-structured models. Materials & Methods: In this experimental study, the fermentative process of single cell protein production was conducted in batch submerged culture with optimum culture medium formulation at 250C, pH 6 and 300 rpm for 200 h in an incubator shaker. At the end of process, the content of shaker flasks was used to analysis glucose concentration, cell dry weight and protein content in cell biomass. Results: The result simulation by Monod, Moser and Logistic models showed 92% 63% and 83% similarity, respectively. Increase in the pH from 3.5 to 6 caused 71% enhancement in protein content in cell biomass. However, pH more than 6 led to decrease in the cell biomass protein content and this values reached to 29% a pH 7. Increases in the initial glucose concentration from 10 to 50 g. L-1 did not show considerable effects on the cell biomass protein content. Cell biomass protein content of the media containing 50 g. L-1 initial glucose was only 5.67% more than the medium contained of 10 g. L-1 initial glucose. Conclusion: The Monod kinetic model was proposed as a suitable model to simulate A. niger behaviour. Furthermore, pH of the media affects cell biomass protein content. However, initial glucose concentration in the media did not show significant effects on the cell biomass protein content.

Since Medicago sativa is the most important forage crop in Iran and many parts of the world, this study was aimed to evaluate the inhibitory effect of alfalfa epiphytic bacteria on the causal agent of wilt disease in in-vitro. Materials & Methods: Undiseased alfalfa leaf samples were collected from different parts of Hamedan province, before its flowering. After isolating epiphyte bacteria from alfalfa fields, the antagonistic effect of isolates was investigated by measuring the diameter of the inhibition zone against alfalfa bacterial wilt. Protein extraction was performed to assess the pattern of protein bands and the variety of the strains. Biochemical tests and PCR were used to identify the isolates. Results: A total of 30 epiphyte bacteria were isolated from alfalfa shoots. Bacterial isolates were identified as Bacillus, Pseudomonas, and Xanthomonas, based on biochemical, physiological and morphological tests. The highest bactericidal effect was related to isolating No. 16 and the lowest to isolates No. 13, and No. 6, respectively. Using molecular and dendrogram methods, isolate No. 16 was most closely related to Pseudomonas monteilii. Conclusion: Epiphytic bacteria isolated in this study showed a good inhibitory effect against alfalfa wilt in vitro. This can be promising for the biocontrol of this disease. However, further studies are needed to prove the efficacy of the isolates in field conditions. Manuscript profile -

Genus Bacillus is one of the most common microbial sources of α-amylase production. The aim of the present study is identification, overexpression and activity analysis of Bacillus licheniformis α-amylase (amyS). Materials & Methods: A polymerase chain reaction was used to identify and isolate α-amylase gene in Bacillus sp. The fragments were introduced into expression vector pET-26 (+). After sequencing, the recombinant vectors were introduced into E. coli BL21 (DE3) for expression. The recombinant enzyme were purified using amicon filter and dialysis bags. α-amylase activity was measured using di-nitro salicylic acid technique. Results: Based on the results, the α-amylase gene was over-expressed in an expression system beyond the native host (Bacillus sp.). Based on the SDS-PAGE electrophoresis, the molecular weight of this enzyme was predicted 54 KDa. The α-amylase showed an enzyme activity about 4.77 U/ml. Conclusion: These results indicated a high expression of this enzyme in an expression system beyond the host, which was due to existence of a strong promoter used in this study, T7promoter. As a result, employment of this system in an industrial scale is recommended due to the secretion of the target enzyme, a proper folding of the enzyme and maintenance of its activity.

Thi MoreBackground and Objectives: Core+1 or F protein is recently identified to be encoded by hepatitis C virus (HCV) genome. Although functional properties of this protein are not still discovered, core+1 seems to play important roles in viral life cycle and pathogenesis. This study seeks to clone and express HCV core+1 gene in a eukaryotic system with the final aim of evaluating its potential roles in cell signaling pathways and resistance of HCV to therapy. Material and Methods: Core+1 gene corresponding to the amino acids 1-162 was PCR-amplified from the original gene of subtype b that was previously cloned in a prokaryotic vector (14). The amplicon harboring 6xHis-tag at C-terminal was subsequently subcloned in the eukaryotic pCDNA3.1+ vector. The Nhe I / BamHI restriction sites, initiation and stop codons as well as kozak sequences were designed in the primers. Constructed plasmid was verified by restriction enzyme analysis and sequencing reactions. Liver cell line of Huh7 was transfected with this plasmid using electroporation and lipofection techniques. Transfection efficiency was checked by co-transfection of pEGFPN1 plasmid and flowcytometry. Finally expression and localization of core+1 protein was evaluated by means of confocal microscopic technique. Results: Restriction enzyme analysis and sequencing reactions indicated the accuracy of cloning procedure. Flow cytometric analysis showed higher electroporation efficiency for transfection of Huh7 cells, in comparison with lipofection method. Finally, results of confocal microscopic microscopy using anti-His antibody confirmed the transcription and expression of core+1 protein in Huh7 cells. Conclusions: Our study resulted in the eukaryotic expression of core+1 protein in Huh7 cells and provided an appropriate tool for future studies on the potential interference of core+1 with intracellular signaling pathways and cellular protein interaction.

Row spacing including of 40, 50, 60, 70 centimeter and five bean varieties including of Sadri, Goli, Akhtar, Pak, Dorsa along with local Pach bean colony as check were randomized in main plots and sub plots, respectively. The greatest seed yield obtained in local Pach bean colony with determinate habit as affected by 50 and 60 centimeter row distances. But, had not significan difeference with Pak variety. The highest pod number per plant and the greatest seed number per plant were shown as affected by the interaction effect between 40 centimeter × Pak variety. The highest harvest index belonged to the interaction effects berween 50 centimeter × local Pach bean colony. In this experiment, the greatest seed protein content obtained as affected by the interaction effects between 40 centimeter × Goli variety. On the basis of this research results, it seems that by decreasing of planting row distances, seed yield is reducted in baens varieties due to radiation deficit within plant canopy, decrement of plant photosynthesis and insufficient allocation of assimilates to bean seeds.

The horizontal factor were irrigation treatments (i.e. IR1: full irrigation, IR2: cutting irrigation at grain dough stage and IR3: cutting irrigation at grain milk stage) and the vertical factor were foliar application of nitrogen as urea (N1: control, N2: foliar application of 20 kg. ha-1 urea at flowering stage, N3: foliar application of 20 kg. ha-1 urea at milk stage and N4: foliar application of 20 kg. ha-1 urea at flowering and milk stage). Based on results effects of irrigation and interaction of treatments on relative water content was significant. Effects of experimental treatments and interaction of treatments on leaf chlorophyll were significant. The main effect of irrigation treatment on canopy temperature and hectoliter weight was significant and highest and lowest values of these traits observed in full irrigation and IR3 treatments, respectively. The experimental treatments and interaction of treatments significantly affect grain protein content and decreasing irrigation resulted in increasing grain protein content. Although by cutting the irrigation, protein content in both of treatments (IR2 and IR3) increased but by considering the grain yield it seems that cutting irrigation at grain dough stage is more suitable.

The traits: forage dry matter yield, plant height, growth vigour, flowering date, leaf to stem ratio and quality traits consisted of dry matter digestibility, crude protein, water soluble carbohydrates, crude fiber, acid detergent fiber, neutral detergent fiber and total ash were evaluated during 2 years (2006-2007) . The results of combined analysis showed significant differences among accessions and among years. Total means of forage dry matter yield were 5.43 , 4.45 t/ha in years 2 and 3, respectively. The results of correlation analysis among traits indicated that selection for higher forage dry matter yield was produced with earlier flowering, tall plant height and major growth vigour. Considering to negative relationship of forage dry matter yield and quality, from between genotypes with high yield, mostly were selected high the amount of leaf to stem ratio, crude protein, dry matter digestibility, water soluble carbohydrates, and total ash and down amount of crude fiber, acid detergent fiber and neutral detergent fiber. For this purpose the genotypes of Khoramabad, Ghara yonja, Flavarjan, Ghazaghestan and Kordestan with average values of 6.5 – 8.5 t/ha forage dry matter yield were tendered for produced synthetic variety.

Information on forage quality of key species is necessary to assess rangelands to supply the feedstock requirements of livestock which depends on growth season and rangeland grazing capacity. This research was conducted in Sari plain region at three growth stages of four rangeland species, including white clover (Trifolium repens L.), sainfoin (Onobrychis sativa), snail medic (Medicago scutellata), and common alfalfa (Medicago sativa) which have three life forms. The samples were randomly collected at three phenological growth stages (vegetative growth, flowering and seed formation). Then chemical analysis was accomplished to determine the contents of crude protein (CP), acid detergent fiber (ADF), dry matter digestiblity (DMD) and metabolic energy (ME). The results showed that the effect of phenological growth stages on forage quality indicators including cell wall free hemicelluloses and digestible dry matter were significantly higher than other indicators. The percentage of ADF on sainfoin and white clover species increased in the later compared to earlier growth stages. Percentage of DMP significantly reduced during phenological stages in these species. White clover had the most nutritive value than other species in beginning of growth and flowering stages.

Millet cultivars (Bastan and Pishahang) were the main factor, no irrigation stress (stages of BBCH55 and BBCH65 and control) were the sub factor and fertilizer level (no fertilizer, farmyard manure 100% and compost 100%) was the sub-sub factor. The results showed that the greatest amount of soluble sugars was 13.62% under the three factor effect of cultivar, no irrigation and fertilizing in Pishahang cultivars with control fertilizing rate and no irrigation at BBCH55 stage. The highest amount of fiber under the three factor effect was 55.44% in Bastan cultivar with farmyard manure 100% and control. The highest protein percentage was in the interaction between cultivar and no irrigation in Pishahang cultivar and no irrigation at BBCH65 stage. Maximum percentage of ash was 8.1648% in Bastan cultivar. The highest dry matter production was 54.14% in the interaction between cultivar and no irrigation in Pishahang cultivar and no irrigation at control stage. According to the results, we can say that both Bastan and Pishahang cultivars have good forage yield and considering their short growing period, they can be used as second crops for forage production. Moreover, severe stress reduces the forage yield and production efficiency. In addition, adding farmyard manure and compost significantly increases the yield in these forage plants.

The main plots considered irrigation regimes (irrigation after 75, 95 and 115 mm cumulative evaporation from class A evaporation pan), and sub-plots considered three wheat cultivars (Sepahan, Ghods and Pishtazs).Results showed that irrigation after 75 and 95 mm cumulative evaporation did not differ significantly for morphological traits, yield and yield components. Delay in irrigation from 95 to 115 mm cumulative pan evaporation significantly reduced grain yield and its components and increased protein percent. Ghods and Pishtaz cultivars had the highest and the lowest number of grain per spike and the lowest and the highest thousand kernel weight and the lowest and the highest grain yield, respectively. It was concluded that by irrigation wheat after 95 mm cumulative pan evaporation, water could be saved by 22% with no significant loss in yield, while grain protein increased by 1.77 percent.

The experimental treatments included three planting dates (1st, 11th, and 21st of May, 2011), the application of humic acid spray at three levels (control, 40%, and 60%),and VC and Parto cultivars. Results from this study suggest that the second planting date provides the best conditions for reducing environmental effects and preserving the dry and fresh weights of the seed (53.57 g/shrub, and 174.97 g/shrub). In addition, the interaction between the planting date and dry weight of the seed, as well as between the planting date and fresh weight of the seed were significant at the level of 5% and 1%, respectively. The cultivars under planting date treatment showed statistical difference at the level of 1% in some traits namely 1000-seed weight, number of seeds per pod, and yield. Among the cultivars, the maximum 1000-seed weight (63.21 g) belonged to the Parto cultivar. In addition, the application of humic acid spray affected 1000-seed weight, number of seeds per pod, and seed yield in different cultivars at the level of 1%; in that, the maximum effect belonged to the application of humic acid 60% spray (66.20 g). On the other hand, such traits as protein content and ash content were not affected by any of the factors. Manuscript profile -

To investigate the effect of fertilizer types and weeds management on yield, yield components and nitrate leaching in soybean an experiment was conducted as split plots in randomized complete block design with three replications in Chalus city in summer of 2013 and 2014. Fertilizers types including chemical fertilizer, manure and nano-chelates spraying as the main plot and weed control in three levels including emergence to flowering, critical period of weed interference and no weeding were considered as sub-plots. The results showed that yield with weeding during the critical period as well as weeding until flowering was achieved in a statistical group and were significantly more than non-control treatment. The highest weeds dry weight was obtained in gweed infested treatment and increasing in weed control time caused their weight loss. Among the fertilizer treatments, the highest dry weed weight was observed by chemical fertilizer application. Maximum nitrate concentration at a soil depth of 80-100 cm were obtained by using chemical fertilizer. Weeds dry weight increased and the nitrate concentration decreased when the weeds control duration was reduced. In general, the results showed that weed control during the critical period increased the grain yield by increasing the yield components. Manuscript profile -

Ascorbic acid and sodium nitroprusside are the substances that make plants resistant to biotic and abiotic stresses. In this study, the effect of drought stress, ascorbic acid and sodium nitroprusside foliar sprays were examined on the qualitative characteristics in summer squash plants. The experimental design was a split plot factorial with two irrigation regimes; irrigation at 75% FC and irrigation at 25% FC, as the main treatments, and combination of sodium nitroprusside at three levels of 0, 50 and M and ascorbic acid at three levels of 0, 10 and 20 mM at flowering stage as subplot that were applied with three replications. The experiment was conducted in 2011 at the Zabol University research farm in Zabol, south Iran. Deficit irrigation reduced seed oil content and chlorophyll a. Also delay irrigation decreased relative water content of leaves. Ascorbic acid spraying increased, chlorophyll a, chlorophyll b, total chlorophyll, protein and oil contents of leaves, but leaf relative water content decreased with the use of ascorbic acid. The concomitant use of 20 mM of ascorbic acid and 100 M of sodium nitroprusside achieved the greatest chlorophyll a, chlorophyll b, total chlorophyll, protein and oil contents and relative water content of leaves.

The experiment was carried out in three separate environments included non-drought stress environment, drought stress in the vegetative stage and drought stress in the reproductive stage. In each environment, foliar application of cytokinin in three stages (control, V5 –V6 and V8-V10) and foliar application of auxin in three stages (control, silk emergence and 15 days after that) was laid out as a factorial design based on randomized complete block design with three replications. The results showed that the maximum protein (10.93%) and soluble sugar (5.80%) in grain were obtained under drought stress in the productive stage whereas the maximum starch (77.37%) and grain dry mater (90.83%) were obtained in non-stress condition. Foliar application of cytokinin in V8-V10 stage, increased convert starch to soluble sugar on the other hand, foliar application of auxin in silk emergence stage caused converting hexose sugars to starch, increasing the sink capacity (grain endosperm) for receiving more starch and also increasing the grain dry mater .

The treatments were consisted of nitrogen fertilizer at four levels: 50, 100, 150 and 200 kg ha-1 and CCC spraying at three concentrations: 0, 1.5 and 3 g.L-1. IThe results of analysis of variance showed that the effect of N on all traits, the effect of CCC on all traits except hundred grain weight and the effect of N and CCC interaction on all traits except hundred grain weight and protein percentage were significant. Nitrogen and CCC had positive and significant effect on yield, yield components as well as protein and oil percentage of seed. In general, increasing N up to 150 kg ha-1 was associated with enhanced quantity and quality of rapeseed crop, whereas more amount of N had no significant effect on yield components but reduced oil percentage of seed. There is no significant difference between 1.5 and 3 g.L-1 CCC spraying. Under no CCC application, N up to 150 kg.ha-1 and under CCC foliar application N up to 200 kg.ha-1 increased grain yield. Exceeded amount of N stimulate tillering and increase infertile tillers and reduce N efficiency, while CCC as a growth retardant increased uniformity intra plants and increased fertile tillers via prolong of development during.

In order to investigate the effects of plant density on quantitative and qualitative forage of three Amaranths in Gorgan region, an experiment was conducted in 2017. The experiment was a factorial based on randomized complete block design with three replications. This experiment was carried out at Gorgan research station of Golestan Agricultural and Natural Resources Research and Education Center. The experimental factors included: The cultivar in three levels (Cim, Loura and Kharkovski) and plant spacing on rows at three levels (5, 10 and 15 cm). Based on the results of the experiment, the spacing on the row and different cultivars caused a significant difference in fresh forage yield, dry forage yield, percentage of crude protein, crude protein yield, non-soluble fiber in neutral detergent (NDF), percentage of lignin, calcium and phosphorus. Interaction effects were significant only on lignin, calcium and phosphorus percentages. The highest fresh forage yield, dry forage yield obtained at a spacing on row of 5 cm. In three genotype with increase spacing on row, calcium and lignine decreased. But the amount of phosphorus did not follow a particular trend. Also the highest percentage of crude protein, crude protein yield, NDF and crude fat observed in Loura. The dry forage yield of Loura less than other genotypes. However, in terms of qualitative and nutritional characteristics, forage was favorable. Therefore, using this genotype is desirable in order to achieve high quality forage. Manuscript profile -

By having efficient siRNAs against CREB, it may be possible to assess the role of molecules involved in signaling pathways in different cell types. In this research the efficiency of CREB knockdown by 2 different siRNAs in HeLa cells has been studied. Materials and methods: HeLa cells were transfected by siRNAs using Lipofectamine 2000. RNA extraction and cDNA synthesis have been done. The efficiency of CREB knockdown has been assessed by quantitative relative real time PCR. According to our results only one of the siRNAs has a high level of inhibitory effect on CREB gene expression in HeLa cells. The expression of CREB by this siRNA was knocked-down by 64.4% in HeLa cells. Conclusion: By using efficient siRNA specifically for knocking down of CREB gene, we can apply this efficient siRNA in different cell types due to study of signaling pathway which CREB may be involved.

Iron magnetic nanoparticles MoreDue to physico-chemical properties of nanoparticles as drug carriers are widely used in the treatment of cancerous cells in living environments. The nanoparticles can be used for targeted drug delivery and effective to the site of infection. Iron magnetic nanoparticles have biologically active properties and can enter into the reticuloendothelial system by phagocytosis or endocytosis, or can be trapped by phagocytic cells such as monocytes, macrophages and oligodendrocytes. The nanoparticles can hurt cells by increasing oxidative stress. P53 is a tumor suppressor protein and it is disabled or impaired function in most human cancers. The aim of this study was to evaluate the effect of iron oxide nanoparticles on the expression of P53 protein in the brain tissue of mice Balb/C. For this purpose, 15 male mice were divided into three groups (five in each group). The treatment groups 1 and 2 during 8 days, received doses of 100 and 300 ppm magnetic nanoparticles of iron daily by intraperitoneal injection. At the end of eight days, the animals dissected and their brains were removed and were undergone immunostaining with Avedin. The results showed that iron oxide nanoparticles penetrate into brain tissue and causing inflammatory response and cause increasing in P53 protein. It seems that high concentrations of iron oxide nanoparticles have a significant effect on the expression of P53 protein. Manuscript profile -

Exercises and diet modification can affect oxidant and antioxidant factors. The aim of this study was to investigate the effect of high-intensity interval training (HIIT) and high-protein diet (HPD) on total oxidant status (TOS), total antioxidant capacity (TAC) and the ratio of TAC to TOS in the heart tissue of obese male rats. Forty 12-week-old obese male rats (Lee index above 310) were divided into five groups of eight including HIIT (5-12 intervals of 30 seconds with an intensity of 90% VO2max, 5 sessions per week, 10 weeks), HPD (about 57.5% of total calories from protein), HIIT+HPD, obese control-1 (OC-1) and obese control-2 (OC-2) and eight non-obese mice were also divided into the non-obese control (NC) group. became After 48 hours from the last intervention session, heart tissue was removed to measure TAC and TOS levels. Data were analyzed using one-way analysis of variance, post hoc Tukey, Kruskal-Wallis and Mann-Whitney tests at a significance level of p ≤ 0.05. The results showed that the TAC level of heart tissue in the HIIT, HPD, HIIT+HPD groups was significantly higher than in the OC-1 group. On the other hand, the TOS level of heart tissue was significantly lower in the HIIT and HIIT+HPD groups than in the HPD and OC-2 groups. Also, the ratio of TAC to TOS was significantly higher in the HIIT and HIIT+HPD groups compared to the OC-2 group. According to the results, a combination of HIIT and HPD improves TAC and TOS of heart tissue. It seems that HIIT together with HPD strengthens the antioxidant system and reduces oxidative stress in obesity conditions. Manuscript profile -

The aim of this study was to evaluate the effects of human endometrial stem cells with the anti-inflammatory drug pomalidomide on glutathione (GSH) and serum lipids (total cholesterol,TC and low density lipoprotein, LDL)) in the Parkinson’s model in male Wistar rats. Male rats were randomly assigned to five groups (8 animals in each group) including: control, Parkinson’s, and 3 experimental Parkinson’s groups receiving stem cells, pomalidomide, and a combination of stem cells and pomalidomide. Parkinson’s was induced by injection of 6-hydroxy dopamine (concentration 6 μg) in the striatum by stereotaxic method. In the fourth week after surgery, the three experimental groups were treated with 4 mg/kg/daily of pomalidomide, 100,000 stem cells through intranasal route, and a combination of pomalidomide at a dose of 4 mg/kg/daily and 100,000 stem cells. At the end of day 28, blood samples were taken from the groups and factors were measured. The results revealed a significant increase in glutathione among the treated groups compared to the Parkinson’s group. There was also a significant decrease in glutathione in Parkinson’s group compared to the control group. Comparison between Parkinson’s group and the group treated with pomalidomide and endometrial stem cells showed a significant reduction in cholesterol. Moreover, LDL levels showed a significant decrease in LDL levels in the treated groups compared to the Parkinson’s group. Considering the improvement of the measured factors in Parkinson’s rat, allogeneic stem cells can be used as a potential source along with pomalidomide in future research for the treatment of Parkinson’s disease.

Ruminal degradability of dry matter (DM) and crude protein (CP) of barley grain were determined by nylon bags method using eight rumen cannulated rams that received different levels of saline water including control group (480), 4000, 8000, and 12000 mg/l total dissolved solids (TDS). There was a significant difference between experimental treatments in terms of the degradability of DM and CP in all incubation times except the initial time. In the final incubation time, the ruminal degradability of the DM and CP of barley grain were higher in saline water received treatments than the control group. There was a significant difference between the effective degradability (ED) of DM and CP in the experimental treatments. So, the effective degradability of DM and CP of barley grain often increased with increasing salinity. The quickly degradable protein (QDP) fraction was not affected by experimental treatments but the slowly degradable (SDP) protein fraction increased significantly at the maintenance level of nutrition (2%/h); the highest level of SDP was obtained in treatment containing 8000 mg/l TDS. From the viewpoint of metabolizable protein (MP), there was a significant difference between experimental treatments at the maintenance level of nutrition. The lowest MP was observed in treatment containing 8000 mg/l TDS. In overall conclusion, saline water consumption in the experimental animals seems to affect the ruminal degradability of barley grain and leads to an increase in the effective degradability of DM and CP and a decrease in the amount of MP at the maintenance level..

To overcome the limitations transposons, which are mobile genetic elements and have the ability to cut and insert target fragments in certain regions of the genome with the “Cut and Paste” mechanism, are effective. This research aims to evaluate the effect of the PiggyBac transposon vector on the expression level of recombinant Erythropoietin (rEPO) protein and to find a cell line with high expression. First the optimized rEPO sequence based on CHO codon performance was cloned into the pOptiVECTM plasmid. To create the second expression vector, the EPO-IRES-DHFR fragment was inserted into the PB513B-1 plasmid, and then the homogenization steps in both vectors were confirmed using Colony PCR reaction, enzyme digestion, and Sanger sequencing. In order to create a stable cell line, both vectors were separately transfected into CHO DG44 cells and then screened. After confirming the insertion of the vectors into the genome of the target cell, the level of erythropoietin gene expression at the transcript and protein level was checked using qRT-PCR and western blotting tests, respectively, in two cell lines. The Real-Time PCR data indicate a 188-fold increase in erythropoietin gene transcript in the PB513B-1-EPO cell line compared to pOptiVEC-EPO. Additionally, the western blotting test's result confirmed the correct synthesis and secretion of this protein. Analysis of findings in this research revealed that the transposon element significantly increased the expression of the desired gene at the transcriptional level and had could create a cell line with high expression of the target protein.

High sensitive C-reactive protein is the most sensitive inflammatory marker that recently its serum level predicts risk of cardiovascular disease is suggested. Both garlic (Allium sativum) and lemon (citrus limon) are used in the traditional management of CVD without a scientific evidence of the benefit of their combination. This study designed to investigate the hypolipidemic and anti-inflammatory effects of combined extracts of A. sativum and C. limon in male Wistar rats after high-fat diet for eight weeks. For this purpose, 42 adult male rats of Wistar strain, with weights between 200 and 250 gr, were divided into six groups (n=7). Group control and Exp3 was fed on normal pellet diet while group control fat, Sham, Exp1 and Exp2 fed on high-fat diet for up to 8 wk. The combined extract was administered to rats in graded doses for 4 wk and blood serum was analyzed for C-reactive protein and total cholesterol.Results are expressed as means ± SE. Significance differences of biochemical measurements were analyzed by using repeated measure and ANOVA tests to identify differences in phases and among groups. When appropriate, a Tukey posthoc was applied. Statistical significance was accepted at PA. sativum and C. limon was recognizable. However, future long-term well-designed investigations would provide valuable information to establish public health recommendations on the combined extract, taking into account both the nature of the compounds and the optimal dose, for cardiovascular health protection Manuscript profile -

Accordingly, between the total length, and standard length and the weight of three filets, there was a great difference (P >0.05). The maximum amount of protein (18.6%) found in 150-250 gr filets and its lipid was 2.3%. The minimum amount of protein (17.05%) was measured in 15-25 gr filets with 46.2% lipid. The maximum amount of ash in 150-250 gr size was 1%, and its minimum amount was measured in 50-70 gr size as 0.53%. As for the saturated fatty acids (MUFA), the maximum amounts were measured in the filet of 150-250 gr fishes, and its minimum amount was found in the filet of 15-25 gr fishes (P>0.05). In fatty acids (PUFA), the maximum amounts of these acids were measured in filet of 150-250 gr fishes, and its minimum amount was in filet of 15-25 gr as (0.27%). This proportion (DHA/EPA) showed that the increase of size of fish is caused this proportion to be increased. The diminution of diet protein had no negative effect on the growth of fish, and as for the cost of protein, it can be decreased in diet and replaced with lipid. O. mykiss especially, 130-300 gr filets because of having valuable protein and fatty acids, in contrast to two another filets (15-25 gr and 50-70 gr) are very valuable in feeding.

The objective of this study was evaluation of effect of passiflora caerulea leaf hydroalcoholic extract on some biochemical factors in adult male rat. 40 male rats, about 195-200 g each were used in five groups. The control group did not receive any drug treatment, sham group found only distilled water, and experimental groups receiving 150,300,600, mg/kg leaves of passiflora caerulea Hydro-alcohol extract respectively during 21 days. After the end of this period, blood samples were taken from the heart to measure the biochemical factors (urea, creatinine, albumin, total protein). The results were analyzed using SPSS software and comparison of meanings was done using T. test. The results showed that the amount of albumin in the experimental group receiving 600 mg / kg of the extract decreased significantly compared to the control group. Total protein, cratinin and total body weight had no significant changes with control group. Hydro-alcoholic extracts of Passionate flower leaf caused reduction of blood urea nitrogen levels in all experimental groups receiving the extracts as compared to the control. According to the results of this study, it can be argued that the Passiflora caerulea plays a supporting role for the liver, and the lack of liver damage in the rats indicated this issue.

The aim of this study was to investigate the effect of eight weeks of endurance exercises in positive (PST) and negative (NST) slope with royal jelly (RJ) on the hippocampal concentration of protein-carbonyl (PC) and pain tolerance threshold (PT) of Alzheimer’s rats with trimethyltin (TMT). In this experimental study, 49 Alzheimer’s rats with intraperitoneal injection of 8 mg/kg neurotoxin TMT were randomly divided into seven groups :(1) AD, (2) sham (normal saline) (Sh), (3) PST, (4) NST, (5) PST + RJ, (6) NST + RJ, and (7) RJ. To investigate the effect of Alzheimer’s disease on research variables, seven rats were included in the healthy control group (C). PST (with the speed of 16 m/min at positive slope (+15%)) and NST (with the speed of 16 m/min at negative slope (-15%)) interventions were carried out for eight weeks, five sessions per week and 60 minutes per session. RJ (dissolved in normal saline) was intraperitoneally consumed for eight weeks at 100 mg/kg /day. One-way ANOVA test along with Tukey post-hoc test were used in SPSS 22 software to investigate the intergroup difference (P ≤0.05). NST caused to decrease hippocampal level of PC (P = 0.001) and PT, as well as PST caused to decrease PT (P = 0.001). NST + RJ caused to decrease the hippocampal levels of PC (P = 0.001) and PT (P = 0.001) in rats with Alzheimer’s disease. Moreover, PT significantly reduced in the PST + RJ group (P = 0.001). PC hippocampal levels in the NST + RJ group were lower than in the PST + RJ group (P = 0.001). It seems that NST alone and with RJ have analgesic (anti-pain) and oxidative stress reduce effects. Although the interaction of PST and RJ had analgesic effects, the need of more studies on oxidative stress reducing effects is felt following PST and RJ consumption. Manuscript profile -

Therefore, the present MoreAlthough the role of exercise and royal jelly in the health of Alzheimer’s patients has been reported, the interaction effect of these two variables on superoxide dismutase (SOD) and glutathione peroxidase (GPx) is still not well understood. Therefore, the present study was aimed at investigating the interactive effect of positive slope running (PSR) and negative slope running (NSR) with royal jelly on SOD and GPx concentrations in a trimethyltin (TMT) Alzheimer’s animal model. In this experimental trial, 49 rats in the age range of 8-10 weeks, weighing 190-220 g, Alzheimer’s with 8 mg/kg TMT were assigned into seven groups including group one: TMT, group two: sham, group three: Royal jelly, group four: positive slope, group five: negative slope, group six: royal jelly + positive slope and group seven: Royal jelly + negative slope. Moreover, to investigate the effect of Alzheimer’s induction on the research variables, seven healthy rats were included in the healthy control group following the positive slope and negative slope exercises for eight weeks, three sessions per week and each session ran for 60 minutes on a positive 15 and negative 15 slope on the treadmill. Besides, 100 mg/kg of royal jelly was peripherally injected into rats daily. One-way analysis of variance (ANOVA) with Tukey post hoc test and two-way ANOVA with Bonferroni post hoc test in SPSS 22 software were used to analyze the data (p ≤ 0.05). Negative slope increased SOD and GPx in hippocampal tissue of AD rats. PSR and royal jelly increased GPx. Positive slope and royal jelly and negative slope and royal jelly groups had a significant effect on increasing SOD and GPx. Positive and negative slopes and royal jelly seem to improve antioxidant defense; furthermore, the interaction of positive slope and royal jelly and the interaction of negative slope and royal jelly are more desirable than the effect of each alone.

Modifying the lifestyle through sports activities and herbal medicines is one of the solutions to combat this problem. The purpose of this study was to evaluate the effect of an 8-week cinnamon consumption with and without high-intensity interval training on blood lipid profiles in high school-aged overweight girls.Methods: In this semi-experimental study with a pre-test and post-test design, 36 overweight women aged 15-18 years were randomly assigned to one of the 3 groups: intense interval training (n=12), cinnamon supplementation (n=12) and intense interval training+cinnamon (n=12). The intense interval training program was conducted three times a week for 8 weeks in the two intervention groups. Each session, lasting 30-35 minutes, involved high-intensity exercises at 90-95% of peak oxygen consumption. Diet groups received cinnamon supplements at the rate of 6 grams/day for a period of 8 weeks. Body measurements (weight, body mass index) and serum levels of blood fats (cholesterol, triglyceride, high-density lipoprotein, low-density lipoprotein) were measured before and after the study. The data were analyzed using the dependent t-test and analysis of covariance at a level less than 0.05.Results: After 8 weeks of intervention, a significant decrease in body weight and body mass index and a significant increase in HDL cholesterol were observed in the intense interval training and intense interval training + cinnamon groups compared to the cinnamon alone group (p≤0.05). However, Bonferroni's follow-up test did not show significant differences in cholesterol, triglyceride and low-density lipoprotein levels between the groups (p≥0.05).Conclusion: High-intensity intermittent exercise with cinnamon consumption can reduce body composition and some blood lipids more effectively than cinnamon supplementation in overweight high school girls.

Cropping cycle, under alpha lattice design with two replications under two normal conditions and foliar manganese. Foliar Manganese at a concentration of 1 kg/ha was carried out in three stages of planting, stemming and flowering on 148 spring barley cultivars. The results showed that in different growth stages, foliar manganese increased the height, fresh and dry weight of forage, number of tillers per plant, leaf to stem ratio and reduction of seed to forage ratio, compared to normal treatment. Manganese solution increased Crude Protein, Crude Fiber, Acid detergent fiber, Natural detergent fiber and acid detergent lignin traits, as well as reduced qualitative characteristics of dry mater digestibility, Water soluble carbohydrate and ash compared with normal treatment. Simple correlation coefficients between traits showed that there is an inverse relationship between quantity and forage quality. As a result, the factors that increase the amount of forage reduce its quality and vice versa. In the following, using factor analysis, 14 variables were defined in five factors for normal conditions and four factors for manganese soluble conditions which justify 80.81% and 83.85% of the variation of the data, respectively. They made the results of this study indicated the total digestibility of dry mater digestibility, Water soluble carbohydrate, acid detergent fiber and natural detergent fiber from the oral parameters of forage, which can influence on forage quality and animal feed.

Experimental factors were: fertilizer levels (0, 40, 80, 120 and 160 kg N ha-1) and plant density (150, 300 and 450 plant m2). According to the data analysis, effect of nitrogen and plant density on all traits except harvest index were significant. Means comparison showed by increasing at N fertilizer; plant height, grain number per spike, 1000-seeds weight, biological yield, chlorophyll index and protein percentage were increased. But, by increasing at plant density; grain number per spike, 1000-seeds weight, chlorophyll index and protein percentage were decreased. The traits such as spike number per m2, grain yield and protein yield were affected by fertilizer × density interaction, significantly. The highest grain yield and protein yield (500 and 68.50 g m-2, respectively) were achieved at 160 kg N fertilizer × 300 plant per m2 treatment. So, pay attention to the results of present research, it seems that density of 300 plants with consumption of 120 kg N ha-1 is suitable for producing maximum grain and protein yields of wheat.

Acute myocardial infarction has a 30% mortality rate, and noting the MoreIntroduction: acute myocardial infarction (AMI) is one of the most common diseases, affecting the industrialized and developing worlds with an annual prevalence of 650,000 in the United States alone. Acute myocardial infarction has a 30% mortality rate, and noting the importance of its complications many methods have been introduced to estimate the severity and prognosis of the disease. One serologic method is determining CRP, whose serum levels reflect the severity and involvement of acute cardiac muscle involvement. Till now many studies have looked at CRP as a predictor of prognosis in patients suffering from acute myocardial infarction, yet the results proved unsatisfactory in predicting short term mortality (1 month). In this study we will measure serum levels of hsCRP and compare it with their prognosis. Aim: to assess the relation between CRP serum levels with 1 month mortality of patients suffering from AMI. Materials and Methods: in this cross-sectional study blood samples were drawn from patients with chest pain and a diagnosis of AMI, 24 hours after admission to the CCU. The samples were mixed with either heparin or EDTA and were quickly sent to the lab and kept at 2-8 degrees Celsius for a maximum of 8 days (if frozen samples can be stored for up to 3 months). In the lab samples’ CRP forms a complex with anti-CRP polyclonal antibodies on latex and will cause turbidity. The amount of turbidity indicates the CRP level present in the sample. The relationship is calculated via enforced immunoturbidity after analysis with a two point photometer. The kit used in this study had a sensitivity of 0.1 to 20 mg/dl (Pars Kit Azmoon). Based on the kit used, the normal level in adults was considered below 5mg/dl. The patients were fallowed up 30 days post AMI. Results: 85 AMI patients were included in this study from which 15 expired within the first month after the infarction. Mean hsCRP levels in the deceased was 8.89, and in the survivors 6.39 mg/dl (P=0.146). Also 60% of the decease revealed high hsCRP (>5mg/dl), while in the survivors 45% revealed high hsCRP. Conclusion: considering other risk factors in the population under study which can increase a patient’s mortality risk, it can be said that hsCRP’s can play a relative role in predicting of 1 month prognosis of AMI patients. Moreover, this valuable index must be used alongside other risk factors for a precise estimation of prognosis in AMI patients. Manuscript profile -

The result showed that, Cutting irrigation at both flowering and grain filling stages significantly reduced biological yield and grain yield, but the severity of this reduction was greater for stopping irrigation at flowering time. The highest grain yield was observed in the optimal irrigation treatment at 6667 kg ha-1. Non-Irrigation at the beginning of flowering and seed filling stages resulted in a yield reduction of 30 and 18.6%, respectively. The average weight loss of TKW due to stress at flowering and grain filling stages were 35.5 and 29.7%, respectively. On the other hand, stress caused an increase in protein content as well as moisture content of gluten, while the amount of zinc in grain decreased significantly. Weight loss of 1000 grains of wheat, followed by loss of starch storage increased the protein to starch ratio. There was no significant difference between nitrogen fertilizer supply from urea and ammonium sulfate except for plant height and peduncle length. Foliar application of zinc reduced stress damage on grain yield and increased zinc content from 36 to 38.2 ppm. Manuscript profile -

The statistical format of the design was factorial based on random complete blocks in 3 replications. The factors include sulfur fertilizer at three levels (zero, 250 and 500 kg.ha-1 from biosulfur or thiobacillus sulfur) and zinc element foliar application of zinc sulfate source (ZnSo4, 2H2o) at three levels (pure water spraying, solution Zinc spraying with a concentration of 0.5% and 1%). Zinc sulfate contained 34% pure zinc. The results showed that sulfur consumption had a significant effect on yield and quantitative components of wheat growth. The effect of consumption of this element on gluten, protein and grain content was also significant. Foliar application of zinc also had a significant effect on the weight characteristics of one thousand seeds, number of fertile tillers, grain yield, biological yield and leaf surface index. Also, all the qualitative traits of the grain were significantly affected by this element. The highest grain yield was obtained from the treatment of 500 kg of sulfur with 1% solution of zinc spraying at 6789 kg.ha-1. The combined use of biofuels and zinc increased the yield of wheat grains by 36%. The highest weight of 1000 grains was obtained from the consumption of 500 kg.ha-1 of sulfur and zinc foliar application with a concentration of 1% and a rate of 49.6 g. The maximum gluten in the grain was obtained from the consumption of 500 kg.ha-1 of sulfur and zinc foliar application with a concentration of 1%, respectively. Under the conditions of sulfur consumption, the positive effect of zinc foliar application on this trait increased. Zinc consumption increased the protein content by 10.3% and 17.7% for two concentrations of 0.5% and 1% of foliar application, respectively. The highest percentage of protein was obtained in the treatment of 500 kg.ha-1 of biofuels. The highest amount of zinc was recorded in the treatment of sulfur consumption of 500 kg.ha-1 along with 1% solution of zinc spraying at a rate of 63.30 mg.kg-1. The increase in leaf area index for both sulfur and zinc was significant compared to control. Manuscript profile -

Irrigation was considered as the main factor in threeirrigation levels, i.e., once in 8, 11 and 14 days, and the growth promoting compounds wereviewed as the secondary factors in 5 levels, i.e., the use of humic acid mixed with irrigationwater, amino acid foliar spraying, rooting stimulant, potassium and non-use of growthpromoters was (control). The results of analysis of variance indicated that irrigation had asignificant impact on all the traits studied, and the growth promoters affected the leaf relativewater content, chlorophyll a, protein percentage, number of lateral branches, seed yield, andharvest index significantly. The interaction of the two factors had significant effects on thenumber of lateral branches, seed yield, harvest index, and seed protein percentage. Theapplication of humic acid resulted in increased seed yield, and as the water deficit increased, theeffect of humic acid on increasing seed yield became significant. The highest seed yield was3076.12 kg per hectare observed in the irrigation level of once every 8 days and under thehumic acid treatment, and the lowest level of this trait was 1220.96 kg observed in the irrigationlevel of once 14 days and under the control treatment. It seems that increased irrigation intervalduring the growing season led to yield loss and degradation of physiological properties such asleaf area index, chlorophyll, and leaf relative water content, and the use of compounds such ashumic acid moderated the decreasing drought stress effects to some extent.

In this research, paclobutrazol and nitrogen foliar application was investigated on the yield and grain quality of superwheat hybrid cultivar in Karaj region, in the form of split plots in the form of randomized complete block design with three replications in the crop year 2017-2018. The main factor in this experiment included three different levels of nitrogen (60, 105 and 150 kg/ha) from the urea source, the second factor included two levels of paclobutrazol (zero and 200 mg/liter). The results showed that the application of paclobutrazol increased the grain yield and grain quality of wheat, and with the increase in the amount of nitrogen, the yield, yield components and quality of wheat grain increased. The highest amount of seed yield was 14.05 ton/ha, the number of seeds per spike was 89.35 seeds, the harvest index was 43.41% and the seed protein was 12.44% related to the mutual effects of nitrogen 150 kg per hectare and the application of paclobutrazol. Therefore, in order to increase the yield and quality of wheat grain, it is recommended to use paclobutrazol along with nitrogen at 150 kg per hectare. Manuscript profile -

However, SCC has a low diagnostic accuracy. Therefore, foridentifcation of infected animals new biomarkers with high diagnostic accuracy are needed. Acute phase proteins(APPs) are proteins that are increased (positive APPs) or decreased (negative APPs) in response to inflammation.The objective of this study was to determine the diagnostic value of the milk APPs for the diagnosis of subclinicalmastitis in dairy cows. A total of 90 clinically healthy cows were randomly selected. Of these, 52 cows were considered to have subclinical mastitis based on a SCC higher than 130 × 1000 cells/mL of milk and positive bacterialculture results of milk samples obtained from at least one of the quarters. Milk amyloid A (MAA) concentrationwas measured using a commercial ELISA kit and albumin, α-lactalbumin, β-lactoglobulin, and immunoglobulin(Ig) were measured in whey samples by using cellulose acetate electrophoresis. Diagnostic sensitivity and specifcity and cutoff points for each test were determined via receiver-operating characteristics (ROC) analysis. Signifcant (P < 0.001) increases in the mean and median concentration of MAA, albumin, α-lactalbumin, and Ig werefound in the milk samples collected from cows with subclinical mastitis. MAA was the most accurate test witha diagnostic sensitivity of 92.3% and specifcity of 92.1% at cutoff point of > 1.6 mg/L. The results of this studyshowed that determination of MAA and some milk serum proteins such as albumin and immunoglobulins can beused as potential and reliable biomarkers for the diagnosis of bovine subclinical mastitis.

Salicylic acid is one of the beneficial compounds for plants, which plays an important role in the resistance of plants to environmental stresses, including salinity stress. To evaluate the potential beneficial effects of salicylic acid on some of the physiological and morphological parameters of an experiment, a factorial experiment was conducted in a completely randomized design with two factors: salinity including sodium chloride at 0, 100 and 150 mM and salicylic acid at two levels 0 and 1 mM with four repeats. At the end of experiment, vegetative traits, chlorophyll a, b, total, carotenoids, starch, sucrose and total protein content were measured after 28 days of treatment. The results of salinity and salicylic acid interaction showed that salinity significantly reduced the weight and dry weight of the shoot, root dry weight and root, root penetration depth, and the height of the forage plant. Salinity of 150 mM significantly reduced the amount of chlorophyll a and b. In addition, the amount of sucrose and starch and protein decreased by salinity. Treatments with salicylic acid increased vegetative traits, sugars, chlorophyll, carotenoids and protein under salinity stress significantly. Manuscript profile -

Therefore, with the aim of investigating the nitrogen use efficiency and its components in different cereals under the conditions of control (no use nitrogen) and optimal conditions of nitrogen, a factorial field experiment was conducted base on randomized complete block design with three replications at Gonbad Kavus University in 2017-2018. The experimental treatments included cereals at 7 levels, including bread wheat Koohdasht cultivar, durum wheat Seimareh cultivar, two rowed barley Khoram cultivar, six rowed barley Sahra cultivar, hull less barley Line 17, triticale Javanilo cultivar and oat Canadian cultivar) and the nitrogen factor were evaluated at two control (zero) and optimum levels. The result showed that cereal × nitrogen interaction was not significant on nitrogen utilization efficiency, nitrogen uptake efficiency and nitrogen use efficiency, nitrogen harvest index, nitrogen content and grain protein. But the main effect of nitrogen and cereals on nitrogen uptake efficiency, nitrogen utilization efficiency and grain protein percentage was significant at 1% level. While the nitrogen harvest index was only affected by cereals, Also, nitrogen remobilization was affected by cereals, nitrogen and cereals × nitrogen interaction. Finally, the results of this experiment showed that nitrogen use efficiency increased in all studied cereals under optimal nitrogen conditions. Nitrogen use efficiency consists of two components, nitrogen uptake efficiency and nitrogen utilization efficiency, as a result, the increase in nitrogen use efficiency is mostly due to the improvement in nitrogen uptake efficiency. Also, in all cereals under optimal nitrogen conditions, protein percentage and grain yield increased, in order to the increase in protein percentage was due to increased nitrogen remobilization. On the other hand, hull less barley had a higher nitrogen use efficiency than other cereals. Manuscript profile -

Marandu) or Tifton-85 (Cynodon spp.) sup-plemented with different protein concentrate. 36 H × Z cows (±514 kg of body weight) were used. The cows had ± 65 days in milk and were distributed in a randomized block design, in a 2 × 3 factorial arrange-ment, i.e., two types of grass (Marandu and Tifton-85 grass), three types of protein supplementation (2.0 kg of concentrate with low rumen degradable protein; 2.0 kg of concentrate with high rumen degradable pro-tein; and no concentrate feed). Both grass produced similar amounts of forage mass, kg.h-1. The nutritional value for both grasses was also similar in all the variables analyzed, such as crude fat, crude protein, carbo-hydrates, non-fiber carbohydrates, neutral detergent fiber, and, acid detergent fiber. The milk yield was not affected by the different grasses used for grazing. Only the lactose content was higher in cows grazing on marandu grass than in Tifton-85 grass (P=0.032). The cows that did not receive concentrate had lower daily milk yield (P=0.010) and a lower percentage of lactose (P=0.011). In conclusion, both grasses can be used for grazing F1 ½ H × Z cows, and protein supplementation, regardless of its ruminal degradability, in this situation is necessary to increase milk production.

Three experiments were conducted to assess the impact of replacing soybean meal with CM at different levels during the rearing stages of Ross 308 male broilers on performance, carcass traits, and liver enzyme concentrations. In the first experiment, 420 one-day-old chicks received starter diets with six graded levels of CM from 0 to 15% for 10 days. In the second experiment, 360 eleven-day-old chicks were fed six experimental grower diets varying in CM from 0 to 25% over 14 days. In the third experiment, three hundred 25-day-old chicks were subjected to six finisher diets ranging in CM from 0 to 40% over 18 days. The findings revealed that the inclusion of the CM at the examined levels had no adverse effects on broilers' performance, carcass traits, and liver enzymes in the first and second experiments (P>0.05). Die-tary CM inclusion of more than 32% in the third experiment had significant adverse effects on the perform-ance, European broiler index, and liver enzymes of broilers (P<0.05). In conclusion, the CM can be in-cluded in broiler diets at levels up to 15% during the starter and 20% during the grower periods without adversely affecting growth performance and carcass traits. Nonetheless, an inclusion level of CM exceeding 32% of the diet during the finisher period resulted in decreased weight gain and harmful effects on liver function. Manuscript profile -

It was performed with three replications in the cropping years of 2018 and 2019 in Astana-Ashrafieh city of Guilan province. Experimental treatments included irrigation regime (rainfed and water requirement of 60, 80 and 100%) as the first factor and humic acid (without fertilizer, 3, 6 and 9 L.ha-1) as the second (secondary) factor. The results showed that the interaction of irrigation and humic acid on biological yield and pod and grain yield was significant. The highest grain yield was obtained in the irrigation treatment of 100 and 80% of water requirement and with the use of humic acid 9 L.ha-1 with an average of 2562 and 2526 kg.ha-1, respectively. Biological yield under 80 and 100% water requirement was 6714 and 6772 kg.ha-1, respectively. The highest biological yield was observed in different amounts of humic acid in treatments of 9 L.ha-1 at the amount of 7436 kg.ha-1. Pod yield in the treatment of 80 and 100% of water requirement were 2427 and 2435 kg.ha-1, respectively. The lowest and highest pod yields in different amounts of humic acid were in the treatments without fertilizer and 9 L.ha-1 with an average of 1453 and 2706 kg.ha-1, respectively. Treatment of 80% of plant water requirement and the amount of humic acid consumed at 9 L.ha-1 with an average of 745.5 kg.ha-1, had the highest rate compared to other treatments. According to the research results, the use of humic acid 9 L.ha-1 can be suggested by providing 80% of water requirement as suitable conditions for the study area. Manuscript profile -

In this semi-experimental study, 48 young non-athletes between the ages of 18 and 24 were randomly divided into four groups of 12: control group (no intervention); supplement (whey protein); Interval training and combined group (interval training + whey protein) were included. After measuring the anthropometric indicators, the subjects in all 4 groups were present in the laboratory environment after 10 to 12 hours of overnight starvation (fasting) and after 15 minutes of rest, 5 cc of blood from the brachial vein between 7 o'clock and it was taken from them at 8 am. Blood sampling was taken to measure testosterone and cortisol and calculate the ratio of testosterone to cortisol (pre-test). Then the aforementioned interventions were performed on the studied groups for a period of 8 weeks. Finally, 48 hours after the last training session, blood sampling was done again (fasting) to measure dependent variables (post-test). Also, anthropometric indices were measured after the intervention in all groups. Data analysis by ANCOVA revealed that compared to the control group, interval training combined with whey protein consumption increased testosterone and the ratio of testosterone to cortisol and decreased cortisol in the combined group compared to the control group. Also, the implementation of aerobic exercises combined with the consumption of Selenium Plus improved the mentioned variables compared to the application of each of them alone. In a summary, based on the available findings, it is concluded that the implementation of interval training combined with the consumption of whey protein is associated with more anabolic effects than the application of each of them alone in non-athletic men. However, further understanding of the mechanisms responsible for the anabolic effect of interval training and whey protein requires further studies in this field. Manuscript profile
