1 - Characterization of polynomially bounded α-resolvent families

An important MoreAbstract.The theory of α- resolvent families was developed as a generalization of the classical theory of strongly continuous semigroups and cosine operator families, to study the fractional evolution equations with Caputo derivative of order α. An important problem in semigroup theory and also for cosine operator families is to discuss different type of boundedness (in terms of their generator) for these families. In this paper, we study polynomially bounded α- resolvent families. We impose conditions on the resolvent of a closed and densely defined linear operator to be the generator of an α-resolvent family. We also show that these conditions are necessary in the case of Hilbert spaces. This generalizes the result by T. Eisner on polynomially bounded semigroups. Moreover, since α- resolvent families describe the solutions to fractional evolution equations, with this generation result, we discuss the existence and stability of solutions to these problems at the same time.

In this paper, motivated by the main idea of Samet et al., we introduce the concept of α-admissible α-θ-generalized mappings in metric spaces and give and prove several theorems of the existence and uniqueness of a fixed point in complete metric spaces for such mappings. The results obtained in this study, generalize many of the results in this field, especially, the results presented by Jleli et al. and the work done by Geraghty. By presenting an example, we show that our results are real generalization of the previous results. Next, we get new results in ordered metric spaces and graphical metric spaces using the concept of α-admissible α-θ-generalized mappings. Finally, we present an application of our obtained results for the existence and uniqueness of the solution of nonlinear first-order ordinal differential equations and periodic boundary value problems.

Ethephon can break seed dormancy in a variety of plants, such as cereals and speeds up germination. In some plants pretreatment of seeds with salicylic acid has increased the germination percentage. To study effect of salicylic acid and ethephon on seed germination of wheat (Seivand cultivar) under salinity condition a factorial experiment in a completely randomized design with three replications was conducted at the Plant Research Laboratory of Neyshabur Branch of Islamic Azad University in 2011. Four salinity levels (0, 50, 100, 150 mM), three salicylic acid levels (0, 0.5, 1 mM) and four ethephon levels (0, 0.5, 1, 2 mM) were used. The results showed that at salinity condition seed germination rate and percentage, shoot and root length, their dry weight and α-amylase activity decreased and proline content increased. Pretreatment of seeds by salicylic acid increased seed germination percentage, some growth parameters, α-amylase activity and proline content under salinity condition. Moreover, pretreatment of seeds by ethephon decreased some growth parameters and increased proline content but its effect on germination and α-amylase activity were not significant. It seems that Salicylic acid as a plant growth regulator under salinity condition and ethephon convertion to ethylene, activated plant tolerance mechanisms to salinity condition and decrease damaging effect of salinity on seed germination and seedling growth of wheat.

Cardiac troponin I (cTnI) and tumor necrosis factor alpha (TNF-α) are the important biochemical parameters of cardiac tissue damage. The aim of this study was to evaluate the effects of short term and regular growing long term aerobic exercise on serum levels of cTnI and TNF-α in rats with Ischemia/Reperfusion (I/R) injury. For this purpose, forty male Wistar rats were randomly divided into four equal groups including: control, I/R, I/R with two weeks of aerobic exercise, and I/R with eight weeks of regular growing aerobic exercise groups. Aerobic exercise was performed 5 times per week on treadmill at speed of 10-25m/min for 10-30 minutes with the slope of 5 degrees. For induction of I/R injury, the left descending coronary artery was clamped for 30 minutes, thereafter blood flow was restored for 2 hours. Finally, after collection of blood samples from the retro-orbital plexus for cTnI and TNF-α measurements, all animals were euthanized. Histologic sections were created for TUNEL staining from the hearts. Regular growing long term aerobic exercise significantly (p<0.05) decreased the cTnI and TNF-α serum levels, which were increased due to I/R injury. Microscopically, the numbers of apoptotic cells were significantly (p<0.01) increased in I/R group compared to the control group. Regular growing long term aerobic exercise significantly decreased the number of apoptotic cells (p<0.05). The results showed regular growing long term aerobic exercise protects the cardiac tissue of rats from I/R injury. Conflict of interest: None declared. Manuscript profile -

This study aimed to isolate and to identify a a-amylase producing bacillus in rhizosphere of orange orchards and to investigate microbial activity to enzyme production in presence of different source of carbon ranges. Materials and Methods: This study was conducted in order to isolation of a-amylase bacilli from rhizosphere of orange orchards located at Kerman province, Iran. After sample collection, bacteria were isolated by growing on starch agar. Several molecular (based on 16SrRNA) and biochemical methods were used to identify bacterial species. The starch rapid hydrolysis test was used to investigate amylase activity of the isolates. Additionally, the enzyme production level was studied in the presence of several carbon sources include glucose, fructose and starch ranges. Results: Molecular and biochemical analysis showed that isolated bacterium is a strain of Bacillus cereus named as Bacillus cereus MR-R3 and recorded in GeneBank under accession number of KC306945.1. Moreover, results showed that starch and glucose have the highest positive effects on alpha amylase production in the presence of 0.5 g/l and fructose have the highest effect in the presence of 0.25 g/l. Conclusion: Isolation and identification of orange orchards rhizospher-derived bacillus species considering their ability to produce a-amylase and phosphate solvation showed that the presence of this species in this region is very important. Moreover, increase in production of the enzyme after treatment with different carbon sources can be related to their gene expression induction effects. Manuscript profile -

Physical activity and proper nutrition are factors that play an important role in the health of the nervous system. Boswellia serrata is one of the most important herbs in traditional medicine to enhance memory and prevent Alzheimer's disease. The purpose of this study was to assess the effect of aerobic exercise course combined with the use of B. serrata on the amounts of brain-derived neurotrophic factor (BDNF) and alpha-tumor necrosis factor (TNFα) in elderly men. In this quasi-experimental study, 40 elderly men aged 60-70 yr old who were in complete physical and mental health were randomly divided into four groups (exercise, supplement, exercise + supplement, and control). Participants in the training groups participated in the aerobic walking training program for 8 and 3 wk each week. Moreover, the daily supplementary groups received B. serrata 300 mg in chewing and packaged form. The control group did not participate in any intervention during this period. Fasting blood samples were collected before and 24 h after the last intervention. Data were analyzed using t-test, analysis of variance and Tukey at a significance level of 0.05. In the exercise, supplementation, and exercise + supplementation groups after 8 wk, the levels of BDNF and TNFα increased and decreased significantly, respectively (P≤0.05). In addition, there was a significant difference in BDNF and TNFα levels in the exercise + supplement group compared to other groups (P≤0.01). Doing walking and consuming B. serrata independently and combined significantly increase the expression of BDNF and significantly reduce the inflammatory factors in elderly men. Therefore, it is recommended that the combination of walking and consumption B. serrata as a more effective way to maintain health and extend the cognitive and functional benefits of the brain and the nervous system to the elderly.
