nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...

boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...

Introduction: Exhaustive exercise leads to muscle fatigue and reduces muscle power in response to contractile activity and causes central fatigue. On the other hand, the effects of opioids on skeletal muscles and fatigue phenomenon are not known completely. Thus, the current study aimed to assess the effect of a single dose administration of opium on muscle and central fatigue in male rats. ...

Background and Objective: Since the results of some scientific data on positive effects of caffeine compounds on modulation the inflammatory symptoms have been reported, the present study was conducted to identify the effect of acute different doses of caffeine ingestion on serum tumor necrosis factor alpha (TNF-α) response following a single bout resistance exhaustive exercise in male volleyb...

Background and purpose: Development of the male phenotype and the initiation of spermatogenesis are intricately dependent on the cellular events that respond to androgens. The actions of androgens are mediated by the androgen receptor (AR). The aim of this study was to investigate the association of AR 5'UTR and codon 211 genetic variation with the risk of idiopathic male infertility. Material...
