Introduction: Muslims fast from dawn to dusk during Ramadan. The effects of prolonged food deprivation on endocrine hormones have been studied in healthy adults but no previous study has investigated this effect on children. This study aimed to evaluate the feasible changes in serum level of thyroxin (T3), tetraiodothyronin (T4), thyroid stimulating hormone (TSH) and body composition in pre-men...
background: improving the performance of hiv diagnosis assays is one of the most important ways to reduce hiv transmission. because of the high mutation rate of hiv, it is critical to use the conserved proteins to develop diagnostic immunoassay methods. because integrase is one of the most conserved proteins of hiv, it may be a good target for this purpose. in this paper cloning, purification a...
No report has been published on the economical losses associated with errors in oestrus detection in cows under Iranian intensive dairy management. The following study was carried out to determine the accuracy of oestrus detection by farmers using artificial insemination in Shiraz dairy farms. Milk samples were collected from 179 Holstein milking cows at the time of artificial insemination. Mil...

Introduction: Diabetes mellitus has been demonstrated to affect the reproductive system. The current study aimed to investigate the effect of hydroalcoholic extract of Salvia officinalis (SO) on the serum levels of gonadotropin, testosterone and dihydrotestosterone. Methods: In the present study, 60 adult male Wistar rats were divided into 5 groups (n=10) as follows: control, Stereptoz...
Background: Animal models of psychosocial stress are a good model for studying stress-related behavioral and endocrinological disorders in humans. The aim of present study is to investigate the effect of psychosocial stress on plasma testosterone level and pain perception. Methods: In this experiment 74 male rats (200-250 g) and 20 female rats (200-300 g) were used. In experimental groups (...
BACKGROUND: The knowledge in blood constituents isimportant for assessing the physiological status and the health ofanimals. Only a limited number of two-humped camels (Camelusbactrianus) were reared in Ardabil province, northwest of Iran.OBJECTIVES:The present study was carried out to find out whetherthe sex and pregnancy affect thyroid hormones, lipid andlipoprotein profile, and selected bioc...
Background and Aim: The use of medicinal plants has increased greatly mainly due to their easy availability, fewer side effects and lack of toxicity. The present study was carried out to investigate the antidiabetic effect of the extract of aerial parts of salvia nemorosa in normal and streptozotocin- induced diabetic male rats. Materials and Methods: After collection and taxonomic identificat...
