Introduction: Few researches have been carried out on the effect of selenium supplementation on muscle damage in athletes. The aim of this study is to investigate the effect of selenium supplementation on serum levels of creatine kinase (CK), lactate dehydrogenase (LDH) and muscle strength at resting and after a soccer match in young soccer players. Materials and Methods: The research method was quasi-experimental and 19 young soccer players were selected among soccer players in Saghez city and were randomly divided into two experimental (supplementation, n=10) and control (placebo, n=9) groups. The assessments were carried out in three stages (pre-supplementation, post-supplementation, and immediately after the match). General characteristics of subjects, muscle strength, and circulating levels of LDH and CK were measured. The supplementation period was one month (one 200 µg/ml selenium capsule daily). The placebo group also consumed a starch capsule each day. In order to analyze the data, two factor analysis of variance with repeated measures were used at the significant level of P<0.05. Results: Selenium supplementation has no effect on muscle strength (bench-press p=0.790, leg-press p=0.912) and levels of CK (p=0.051) and LDH (p=0.244) at rest and after the soccer match. Conclusion: Selenium supplementation for one month and a daily intake of 200 μg does not appear to have a beneficial or harmful effect on muscle strength and circulating levels of enzymes indicating muscle damage at rest and following a soccer match in young soccer players. More research is needed to reveal various aspects of the issue. Manuscript profile

Polycystic ovary syndrome (PCOS) is associated with hormonal-metabolic disorders, oxidative stress and ovulation disorders. The present study evaluated the effect of selenium nanoparticles (SeNPs) on the activity of antioxidant enzymes and ovarian tissue structure and oxidative DNA damage in the polycystic ovary syndrome (PCOS) model. 32 female Wistar rats were divided into 4 control groups, PCOS, PCOS+SeNPs0.1 and PCOS+SeNPs0.1. Polycystic ovary syndrome was induced by a single intramuscular injection of estradiol valerate (4 mg/kg) and SeNPs with doses of 0.1 and 0.2 mg/kg were administered orally for 14 days. At the end, the tissue level of superoxide dismutase (SOD), catalase (CAT) enzymes, content of malondialdehyde (MDA) and 8-hydroxydeoxyguanosine (8-OHdG) in the ovarian tissue was measured by ELISA technique and the ovarian tissue structure was examined histopathologically. A significant decrease in the number of follicular cysts, 8-OHdG and MDA levels along with a significant increase in tissue levels of SOD and CAT enzymes were seen in the SeNPs treatment groups compared to the PCOS group. In fact, SeNPs with antioxidant function improved ovarian tissue structure in polycystic ovary syndrome model. Manuscript profile

To evaluate the effect of selenium (from sodium selenate) on increasing efficiency at water deficit condition a research was conducted in Karaj 1 wheat cultivar in 2014-2015 cropping year with split plot based on completely randomize block design with four replications in Karaj. Irrigation treatments with two levels, normal (I1) and interruption of irrigation at mid flowering (110 days after planting) (I2), which were assigned to main plots and selenium foliar application with six concentrations: 0 (S0), 5 (3.12 micro g.) (S1), 10 (6.24 micro g.) (S2), 15 (9.36 micro g.) (S3), 20 (12.5 micro g.) (S4) and 25 (15.62 micro g,) of sodium selenate per plant (S5) g.ha-1 to sub plots. The results showed that water deficit increased the rate of superoxide dismutase, catalase, glutathione peroxidase and malondialdehyde marker. Foliar application of selenium, increased contents of antioxidant (anti oxidation) enzymes under stress condition and was maximum in 20 g. selenium per ha-1. Content of malondialdehyde was decreased and caused significant increase in grain yield. Increasing antioxidants and reduction of malondialdehyde at normal condition was lower. On the other hand, negative effect of malondialdehyde on yield components, cellular membrane stability and antioxidant enzymes at humidity stress condition was higher than normal condition. Significant increase of cytoplasmic membrane stability, grain yield, grain weight and selenium content of seed was obtained when 15 and 20 g. selenium ha-1 were used as compared with those of higher and lower rates of selenium usage under water deficit and normal irrigation. Suppression of free oxygen radicals, and enzyme induction defense mechanisms against oxidative damage has been effective. Therefore, use of exogenous compounds such as selenium may increase the antioxidant capacity of plant against stress. Manuscript profile

Drought stress is one of the major factors limiting crop yield in dry-lands. To investigate the effect of sources and different rates of selenium on physiological traits, yield and yield components of wheat and barley in dry lands a factorial experiment based on complete randomized block design with three replicates was carried out at the Research Station of Islamic Azad University, Arak Branch, in 2014-2015. Experimental factors were selenium sources with two levels, (sodium selenate and sodium selenite), selenium rates with three levels, (0, 18 and 36 g.ha-1) and two crop plant (wheat and barley). The result showed that, foliar application of wheat with 18 g.ha-1 sodium selenite increased the grains per spike by 9.4% as compared to control and foliar application of barley with 18 and 36 g.ha-1 of sodium selenite increased the grains per spike by 8 and 12%, as compared to control, respectively. Two times foliar applications of these two plants with sodium selenate and sodium selenite increased their relative water content. Foliar application by 18 g/ha of selenium increased the grain yield from 1776.31 kg.ha-1 in control to 1889.92 kg.ha-1, while grain yield was decreased (about 1539.62 kg.ha-1) as compared to control when 36 g.ha-1 of selenium was used. It could be concluded that foliar application of 18 g.ha-1 selenium as sodium selenite or sodium selenite in wheat and barley during stem elongation and emergence of spike increases grain yield in dry land condition.

Selenium is an essential element for human and animal heath, with antioxidant and anti-cancer properties. Although, researchers have found it to increase vegetative growth. It is not considered to be essential for higher plants. In order to evaluate the effect of selenium and sulfur on growth and yield of three cultivars of spring wheat a factorial experiment based on randomized complete  block design with three replicates was conducted in pots at the Agricultural Faculty of Islamic Azad University, Tabriz Branch, Iran, during 2009-2010. Treatments were 3 cultivars of spring wheat (Karaj, Pishtaz and Sepahan), 5 levels of selenium (0, 0.2, 2, 5 and 10 mg/kg) in the form of sodium selenate used and 4 levels of elemental sulfur (0, 50, 100 and 150 mg/kg). Results showed that 0.2 and 2 mg Se/kg of soil increased growth and yield in all three cultivars, but 5 and 10 mg Se/kg of soil without sulfur, caused toxicity symptoms, white spots on leaf margins, while its toxicity decreased when 50 and 100 mg S/kg of soil was used and toxicity disappeared by using 150 mg S/kg of soil. This indicates that low levels of Se may have positive effects on growth and yield of wheat through meaningful interaction between Se and sulfur. Manuscript profile

To investigate the effect of foliar selenium nanoparticle applications on the agronomic and yield characteristics of winter oilseed rape, with three levels (0 (control), 25 and 50 mg.L-1) at two growth stages (6-8 leaves and 50% flowering) at the research farm station of the University of Mohaghegh Ardabili during 2018-2019 was studied. The results showed that the selenium nanoparticle applications increased the photosynthetic pigments and the relative water content (RWC) of the leaves significantly. Foliar spraying with 50 mg.L-1 selenium nanoparticle increased in the chlorophyll a and b and total chlorophyll content by 37.04, 44.51 and 39.68%, respectively, as compared to the control treatment. On the other hands, selenium nanoparticle application increased the plant height, number of branches and stem diameter via improving the photosynthetic pigments content and RWC of winter oilseed rape significantly. The biological yield, harvest index and seed oil content of 25 and 50 mg.L-1 of selenium nanoparticle treatments were significantly higher than those of the control. The foliar spraying of oilseed rape plants with selenium nanoparticle applications improved the grain yield throught increase in the number of pods per plant, the number of seeds per pod and the 1000 grain weight significantly. Thus, the highest improvement in the grain yield per unit area (about 34.16 %) was obtained with application of 50 mg.L-1 selenium nanoparticles in comparison with control treatment. In general, the application of 50 mg.L-1 selenium nanoparticles had a positive and significant effect on the physiological (photosynthetic pigments content and RWC) and agronomical characteristics at plants, as to the plant height, branches number, stem diameter, the number of pods per plant, the number of seeds per pod, the 1000-grain weight and seed oil content of winter rape.

This experiment was conducted to evaluate the ability of inhibition of aflatoxin B1 by various sources of selenium and to compare the effect of nano selenium and sodium selenite on humoral immunity of quails. The experiment was performed in a completely randomized design (CRD) using six treatments and four replicates of ten quail chicks per replicate. Two hundred forty quails were divided in six groups vis. control: without aflatoxin B1 and without selenium. Group2: 1ppm aflatoxin B1 and without selenium. Group3: 1 ppm aflatoxin B1 and 0.3 ppm nano selenium. Group4: 1 ppm aflatoxin B1 and 0.3 ppm sodium selenite. Group5: 1 ppm aflatoxin B1 and 0.6 ppm nano selenium. Group6: 1ppm aflatoxin B1 and 0.6 ppm sodium selenite. To evaluate the humoral immunity response 0.2ml of sheep red blood cell (SRBC) solution was injected into breast muscle of quails at day 35 and blood sampling was conducted after a week. Newcastle vaccine was injected at day 28 and the antibody titer was determined after two weeks. The highest level of titer of antibody against the SRBC solution was related to the group which received 0.06 ppm nano selenium (p<0.01). These results indicated that nano selenium in comparison with selenium selenite can improve humoral immunity and blood biochemical parameters. Manuscript profile

Selenium is an important element in nutrition and an essential part of several proteins with catalytic and structural properties. Selenium nanoparticles have a higher effect and less toxicity than conventional selenium. The aim of this study was to demonstrate the strong role of nano-selenium in protecting against ischemia/reperfusion (I/R) injury in a male rat model. In this study, I/R damage was caused by closing the left renal artery for 20 minutes. 54 rats were randomly divided into 9 healthy control groups, Sham, three healthy experimental groups receiving selenium nanoparticle at doses of 0.25, 0.5 and 1 mg/kg alone, I/R control and three groups of I/R mice receiving selenium nanoparticle at doses above, were divided (n=6). Thirty days after administration, animals were sacrificed for biochemical and histopathological evaluation and the data were statistically analyzed (p˂0.05). Selenium nanoparticle in I/R groups significantly decreased serum urea and creatinine levels (p˂0.001) and significantly increased the antioxidant parameters of catalase, glutathione peroxidase and superoxide dismutase and significantly decreased the level of malondialdehyde (p˂0.001) to 0/1. I/R and repair of renal histological damage (p˂0.001). This study showed that selenium nanoparticle has protective effects against damage caused by renal ischemic reperfusion, and this protective effect can be due to its antioxidant properties in improving damage caused by free radicals in the ischemic reperfusion process, thereby improving the structure of kidney’s tissue and reduce oxidative stress.

Selenium has an important role in the metabolism of thyroid hormones because it is necessary in the conversion ofthyroxine (T4) to its active form triiodothyronine (T3). For this conversion, selenoenzymes which are mainly located in the liver and kidneys are necessary. This study was conducted to determine the effects of organic and inorganic selenium (Se) supplementation on serumic levels of thyroid hormones in mixed breed horses. For this purpose, 10 healthy mixed breed horses 4-5 years of age were randomly divided into two equal groups. The first treatment group received routine diet plus premix (1 mg sodium selenite/day) for 12 days and the second group was supplemented similarly with 1 mg commercially available yeast enriched organic selenium (O-Sel). Blood samples were taken by venoject tubes from the jugular vein on days 0, 3, 6 and 12. Serumic selenium concentrations were measured using atomic absorption and serum thyroid hormones were measured by spectrophotometer.  After selenium supplementation, mean serum T3 levels increased significantly in both treatment groups (p<0.05) while T4 concentrations decreased. According to the results, administration of limited amounts of selenium can increase the active form of thyroid hormones with a positive impact on the performance of the horse. Manuscript profile

Strangles is a prevalent infectious and contagious disease among Equidae that is caused by Streptococcus equi subspecies equi. The present study was performed on patient and healthy horses to evaluate serum levels of vitamin C (vitamin C), vitamin E (vitamin E), selenium (Sel) and glutathione peroxidase (GPx). Clinical signs and bacterial culture confirmed sixty patient horses. To separate the serum, blood samples were taken from the jugular vein of the studied horses. Blood samples were also taken from 52 healthy horses with similar conditions (age, diet, etc.). Serum levels of Vit E, Vit C, Se and serum’s activity of GPx were measured in samples taken from healthy and patient horses. The mean serum concentration of vitamin E, selenium and serum glutathione peroxidase activity in patient horses were significantly reduced. A significant increase in the patient's hemoglobin concentration was observed. The study of the relationship between serum selenium and antioxidants (serum glutathione peroxidase activity, vitamin E and hemoglobin) showed that increasing serum selenium also increased the antioxidants studied. Serum antioxidant markers were significant in patient horses in all three cases. The final outcome is that in horses which infected to strangles antioxidants like selenium, glutathione peroxidase and vitamin E reduced and these antioxidant intakes for dealing with them this issue should be considered in treating these patients.

     This study was conducted evaluate the effect of vitamin E and Selenium injection on serumic levels of thyroid hormones in the Arabian horse. Twelve Arabian stallions of approximately equal age were selected and based on their age (4 and 5 years old), allocated to tow groups each consisting of six animals. In each group, three of the six horses were injected by vitamins E and selenium at a dose rate of 1cc/30 kg intramuscularly every tow days and the other three animals which were chosen as the controls were similarly injected by normal saline solution. Two days alter each injection; blood samples of the horses in each group were collected using venoject from the jugular vein. After separating the blood serum by centrifuging, the levels of T3 and T4 were measured using the ELISA technique. Following the first injection, the serumic levels of thyroid hormones demonstrated a significant increase in comparison with the controls (p<0.05) while after the second injection, the serumic levels of T3 and T4 had decreased to normal values similar to the control groups. However, following the third injection the decreased in T3 and T4 levels was clearly evident and statistically significant (p<0.05). According to the results of the present study, the injection of vitamin E and selenium for more than twice leads to decrease in the seumic levels of T3 and T4 hormones of the horse and this is coupled with reduction of the basic body metabolism which is not beneficial for the animal.

   Co-administration of vitamin E and selenium has positive effects on growth performance of avian species, but their effect is not fully elicited in the Japanese quail. Also, controversial reports exist for the effect of vitamin E and selenium on avian performance. This study was designed to investigate the effect of different levels of selenium (0, 0.2 and 0.4 mg/kg) and vitamin E (0, 150 and 300 mg/kg) in the diet of the Japanese quail. Birds received mesh diet from the start of the study, then selenium and vitamin E were added on day 17. At the end of the study, after food deprivation for 6 hours, Japanese quail (1 male and 1 female) were selected and blood samples collected for biochemical investigations and determination of glucose, albumin, total protein, cholesterol, triglyceride, HDL and LDL levels. There was significant decrease in cholesterol, glucose, and triglyceride levels and significant decrease in albumin and total protein levels on day 35 (p<0.05). Effect of vitamin E and selenium was not significant on serum LDL level but, administration of vitamin E significantly increased serum HDL levels (p<0.05). These results suggest that co-administration of selenium and vitamin E could have positive effects on blood biochemical parameters in the Japanese quail. Manuscript profile

The objective of the present study was to study the comparative effect of administering selenium nanoparticles and sodium selenite in pregnant ewes on the blood serum levels of thyroxin in newly born lambs. For this purpose, twenty, four-month pregnant ewes within the same age were used. During the 21 days leading up to birth, supplementation of selenium nanoparticles (Se NPs) with dosages of 0.05 and 0.10 mg/kg B.W. were respectively fed to treatment groups 1 and 2. And supplementation with sodium selenite with dosage of 0.1 mg/kg B.W. was fed to treatment group 3. At the same time the control group was fed distilled water in equal volume. The ewes were monitored under accurate laboratory and clinical examination until the time of delivery. Neonatal lamb serum thyroxin level was measured at the day zero (birth day) and also at the 7th day. The results indicated that serum thyroxin level of neonatal lambs of treated groups 1 and 3, decreased significantly at 7 days' age in comparison to the birth day (p values less than 0.006 and 0.001, respectively). Results also showed that serum thyroxin level of group 2 offspring lambs on the day 0 was significantly less than that in group 1 (p=0.003). It was concluded that the physiological function of selenium nanoparticles was dose dependent, and the 0.05 mg/kg B.W. dosage of Se NPs induced similar effects like 0.1 mg/Kg B.W. of sodium selenite, which resulted in increasing serum level of thyroxin at the day of birth.  Conflict of interest: None declared.

This study was performed to evaluate the effect of vitamin E and Selenium injection on serumic levels of albumin, protein, calcium, phosphorous, alkaline phosphates, alaninamonitransferas and aspartataminotransferas in the Arabian stallions. In this study 12 Arabian horses were selected in 2 groups of 4 and 5 years old. In each group, horses were allocated to two sub groups of controls and treatment, each of them containing three animals. In the treatment group, 1cc/30 kg vitamin E and selenium was injected intramuscularly in 2 day intervals for 6 days, while in the control group the same amounts of normal saline (0.9%) was injected. Blood samples of all animals were collected from the jugular vein at days 2, 4 and 6 and their sera were harvested by centrifuging and the levels of the parameters were measured using commercial kits and the spectrophotometric method. The results of this study indicated that there was no significant difference on mean serumic albumin, phosphorous, alkaline phosphates, alaninamonitransferas, and spartataminotransferas in the studied animals while mean serumic protein values of 4 year old horses indicated a significant difference following the third vit E – Selenium injection (p<0.05). The levels of calcium showed a significant difference following the second injection in 4 and 5 years old horses (p<0.05). Based on the results, it can be concluded that vit E – Selenium injection could be beneficial for horses without having any side effects on the liver and kidney but alterations of other biochemical and hematologic parameters should also be investigated.  Manuscript profile

Salt stress is one of the most important environmental threats that adversely affects the growth, development, and productivity of plants; therefore, suitable approaches are needed to mitigate its negative effects on plants. For this purpose, a pot experiment was carried out in a completely randomized design with two treatments include salinity (0, 25, 50, and 75 mM) and foliar application of selenium (0, 5 and 10 µM Na2SeO4), and the possible role of selenium in regulating Moldavian balm salt tolerance was investigated. Foliar applications of selenium were applied after seedlings establishment at three stages, simultaneously with the application of salinity stress, and then at weekly intervals. Results indicated that growth indices, photosynthetic pigments, and relative water content of leaves in Moldavian balm plants were decreased significantly by various levels of salinity stress. Foliar application of selenium especially at the low concentration increased all the mentioned traits in stress conditions. In contrast, high level of selenium magnified the negative effect of salinity, so that the highest value of malondialdehyde, electrolyte leakage, and water potential were obtained by 10 µM selenium under 75 mM NaCl and caused the accumulation of proline and soluble sugars. This study indicates that selenium at low concentration plays a significant role in alleviating the harmful effects of salinity through photosynthetic pigments, maintaining membrane integrity, reducing water potential, accumulation of compatible solutes, and consequently, improved the performance in Moldavian balm plants growing under salt stress.

In order to investigate the effects of foliar and root application of selenium (0 and 20 µM) on some physiological and biochemical parameters of wheat (Triticum aestivum L.) var. Chamran under salt stress (0 and 100 mM NaCl), an experiment was conducted hydroponically based on  a completely randomized factorial design with three replications at Payame Noor university in 2017. Results showed the significant decreases in growth parameters, chlorophyll to carotenoids ratio, and chlorophylls and total protein contents while significant increases were recorded in malondialdehyde, proline, anthocyanin, and total phenol contents of plant shoots under salt stress. Under control condition, both forms of selenium application significantly decreased the root length while increasing the total phenol content. Moreover, significant increases in proline and carotenoids contents were found under foliar application of selenium in control plants. Under salinity stress, foliar application of selenium significantly increased the root length and shoot fresh weight and its application at both forms improved the other growth parameters of plants. Likewise, significant increases in protein and chlorophylls contents of plants by foliar application and soluble sugars and total phenols contents of plants by both forms of application of selenium were attained under salinity. Only foliar form of application of selenium could decrease the malondialdehyde content of plants under salinity stress. According to the findings, selenium application, especially through leaves, played a remarkable role in ameliorating the effects of salt stress in wheat.  Manuscript profile

In order to investigate the effect of salicylic acid and selenium foliar application on physiological characteristics and yield and yield components of safflower under drought stress conditions, an experiment was conducted as split plots based on randomized complete blocks design with three replications. The main factor included irrigation in three levels, complete irrigation during growing season (control), cutting irrigation at 50 percent flowering stage and cutting irrigation at 50 percent head forming stage. Sub factor was considered foliar application of safflower plants including nonspraying (control), foliar application by salicylic acid, selenium and salicylic acid with selenium. Drought stress reduced biologic yield, yield components and grain yield, but it increased protein percentage, the superoxide dismutase activity and proline concentration. Also, the highest negative effect of drought tension was observed in flowering stage, so that stress at flowering stage reduced 49 percent grain yield and 33 percent biomass of safflower. Foliar application improved yield, yield components and superoxide dismutase activity compared to non-spraying (control). However, between foliar application treatments in grain yield and superoxide dismutase activity, no significant difference was observed, but foliar application of salicylic acid with 7198 kg ha-1 showed the highest biomass. The foliar application in stress and non-stress conditions increased grain oil percentage, so that in complete irrigation and flowering stage stress , the highest grain oil percentage was belonged to salicylic acid foliar application with 24 percent and salicylic acid foliar application with selenium 28 percent. The foliar application treatments increased proline concentration in stress conditions compared to control and at flowering stress stage, salicylic acid and selenium foliar application with 11 micro Mol per gram fresh plant weigh showed the highest proline concentration. Keywords: Grain yield, Oil percentage, Proline and Safflower. . Manuscript profile

Selenium (Se) is not an essential nutritious element for plants; although, the element is absorbed by them. Molybdenum (Mo) is a trace element/heavy metal, a potential toxicant in plants and other organisms in high amounts. We investigated the effects of Se-Mo interactions on the contents of photosynthetic pigments in tomato (Lycopersicom esculentum Mill. Cv. Early Urbana111). Chlorophylls a and b, beta-carotene and xanthophylls were spectrophotometrically measured (Jenway, UK) in leaf extract samples. Dry weight was also recorded. Se showed no significant effect on shoot dry weight, but statistically significantly reduced root dry weight. Also, Se increased the contents of photosynthetic pigments. Mo had toxic effects as it linearly decreased total dry weight and significantly reduced the contents of leaf photosynthetic pigments. Se detoxified Mo at 1- and 2ppm levels. It was concluded that Se is able to improve Mo-related stress symptoms. Manuscript profile

The study is designed with the aim of studying the effect of different levels of selenium fertilizer and cow manure on the concentration of selenium in alfalfa. For this purpose, a pot experiment with complete randomized design in the form of a factorial experiment was carried out with five levels of selenium fertilizer (0, 5, 10, 20 and 40 g ha-1), and two levels of cow manure (Zero and 100 tons per hectare) with three replications in the greenhouse, using Lavark soil of research farm of Isfahan University of Technology in 2016. The selenium content of the samples was measured using atomic absorption device. The results of the experiment showed that the effect of selenium fertilizer levels on selenium concentration in the plant was significant in all three harvestings, but selenium concentration showed consecutive decreases in the consecutive impressions. Increasing the application of cow manure significantly increased alfalfa yield in all three harvests, and the average harvest yield was more than the second harvest, and it was more than the first harvest. The use of animal manure reduced the concentration of selenium in plants and decreased in successive consecutive. In general, selenium fertilizer without the presence of animal manure increased the concentration of selenium in the studied plant. Manuscript profile

Selenium is a beneficial element with antioxidant properties that increases plant growth and tolerance to abiotic stresses. In order to investigate the effect of Nano Selenium solution treatments on Cherry Tomato plant growth, treatments including Sodium Selenate (bulk) and Selenium nanoparticles were applied at four levels (0 as control, 2, 4 and 10 ppm). The experimental results showed that interaction between Selenium nanoparticles and all studied traits (fresh weight, dry weight, anatomical indices of roots and stems and leaves, chlorophyll content) were significantly different at 1% level. Treatments caused morphological changes in stems, roots and leaves compared to controls. The highest increase in root and leaf diameter was observed in group four Nano Selenium (21.55 and 1.1%) compared to the control. All treatments reduced stem diameter compared to control. An increasing trend of root and stem central cylinder thickness was observed in proportion to the concentration compared to the control. Both Nano-Selenium and bulk Selenate reduced the differentiation of xylem vessels in leaves compared to the controls. The results of studied morphological and anatomical traits indicated that the use of two levels of Nano-Selenium concentrations, 2 and 4 ppm, improved the growth parameters, in contrast, application of 10 ppm Nano-Selenium concentration reduced the growth parameter, the content of plant pigments in comparison with the control sample. Overally, the results showed that Selenium treatment in appropriate amounts can contribute to the optimal yield of cherry tomatoes and increase plant growth and pigmentation and affect tissue differentiation and organ development.

Background & Objectives: Selenium nanoparticles have a wide range application in industry, biomedical and environmental fields due to their unique physical, chemical and photoelectrical properties. This study was aimed to use aquatic bacteria in bioreduction of selenite oxyanioninto elemental nano-selenium. Materials & Methods: Synthesized selenium nanoparticles were characterized by spectroscopic analysis and electromicrographs prepared by scanning electron microscopy (SEM). The efficacy of the antimicrobial activity of the synthesized selenium nanoparticles against some Gram-positive and Gram-negative human pathogenic bacteria was also investigated by the agar well diffusion test. Results: Sixteen selenite-resistant bacterial strains were isolated based on selective enrichment techniques in Tryptic Soy Agar (TSA) medium containing 5 mM selenite ion. Our results showed that Pseudomonas alcaligenes SR5 coastal seawater isolate can reduce selenite oxyanion into selenium nanoparticles. Furthermore, the results showed that extracellular selenium nanoparticles with an average size of 36 nm were formed in an optimum selenite concentration of 3 mM and an optimum initial biomass concentration of 15 g/l, following 96 h incubation at 25ᵒ C at (200 rpm under resting cell condition. Conclusion: The current study is the first report on extracellular synthesis of selenium nanoparticles using P. alcaligenes. The produced bio-nanoparticles showed a growth inhibitory effect against four tested pathogenic bacterial strains. Manuscript profile

Different nutrients affecting male reproductive organs have a significant effect on the prevention and treatment of infertility; one of these elements is selenium. This study was aimed at evaluating selenium nanoparticles (NSAs) in oogenesis and uterine changes in adult female NMRI mice. In this study, 30 adult female NMRI mice were selected and randomly assigned to five groups: controls, Sham and three experimental groups. Control group did not receive any material, the Sham group received solvent and the experimental groups received Nano selenium at three doses of 0.2 mg/kg, 0.3 mg/kg, 0.4 mg/kg for 30 days. The weight of the animals in the experimental groups at the high dose was significantly reduced. The weight and diameter of the ovary declined, but the results were not significant. The number of primordial follicles, primary and secondary follicles, and atretic follicle have decreased. The number of Graafian follicles decreased at the dose of 0.4 mg/kg of Nano selenium and corpus luteum decreased at the dose of 0.3 mg/kg of Nano selenium. The diameter of the secondary follicle was increased, but it was not significant. The diameter of the Graafian follicle did not change. The number of blood vessels in the ovaries was increased, but their diameter did not change significantly. In experimental groups, the diameter of the uterine cavity was significantly reduced. The thickness of the perimetrium of uterine layer was also reduced. The number of uterine glands endometrium decreased in the third experimental group, but their diameter did not significantly change in any of the groups. Nano-selenium caused an increase in the number of primordial, primary and secondary follicles due to its antioxidant effect; and the uterine layer of the endometrium increased and perimetrium and myometrium decreased.

  This study was designed to investigate the effects of Nano-Selenium and Sodium Selenite on performance, carcass characteristics, Glutathione Peroxidase and Superoxide dismutase of Japanese quail under heat stress condition. In this investigation, 300 Japanese quail chicks were used and the chickens were raised to 21 days in the same condition. The experiment was performed in a randomized complete block design (RCBD) with 3 treatments and 5 replicates of 20 chicks per replicate. The chickens daily were included under heat stress condition for 8 h at 34± 0.5oC. The results showed that weight gain and feed intake of chicks fed diets with Selenium Nano particles compared to the other two groups was significant (p < 0.05) as well as the FCR between different groups was no significant difference (p>0.05). The all three different treatments showed no significant effect on carcass composition (p>0.05) and increase in use of Nano-Selenium was more tender than sodium Selenite group, but not significant. The results revealed that glutathione peroxidase and superoxide dismutase activity increased significantly in second experimental group using selenium (p < 0.05). In the present study, superoxide dismutase activity was significantly increased after adding 0.2 mg sodium selenite and nano-selenium (p < 0.05). The group of hemoglobin using selenium sources was significantly increased, but not significant increase in hematocrit. Results in this investigation revealed that Nano-Selenium is a better alternative compare to sodium Selenite. Manuscript profile
