Steroid hormones have a large number of functions in the organism, including the regulation of stress response, the electrolytic balance, and reproduction. The synthesis of these hormones is mediated by a series of enzymes, which produce glucocorticoids, mineralocorticoids, progestins, androgens and estrogens using cholesterol as the metabolic main precursor. In this general way, steroid synthe...

gonadotropin-releasing hormone (gnrh) has neuromodulatory roles in central and peripheral nervous systems. the purpose of this study is to evaluate the effect of gnrh analog (buserelin) on peripheral nerve regeneration. forty adult male rats were divided into buserelin-treated, normal saline, sham surgery, and castrated + buserelin groups. the left sciatic nerve was crushed by a fine forceps an...

results from 110 subjects with cpp, 46 girls (41.8%) were considered as intervention and 64 (58.2%) as control groups. the mean age at initial visit was 7.46 ± 1.03 years. the bmi standard deviation scores in both groups was not significantly different at sixth and 12th months of treatment compared with baseline (p = 0.257 and p = 0.839, respectively). the prevalence of obesity was not signific...

routinely, a bolus of 5.000-10.000 iu human chorionic gonadotropin (hcg) is usedfor the final follicular maturation and ovulation as a standard method. hcg has thesame effect of luteinizing hormone (lh) with long half-life. it has the longlutheotrophic effect which increases the risk of ovarian hyper stimulation syndrome(ohss). recently, gonadotropin-releasing hormone agonist (gnrh-a) trigger h...

background: gonadotropin-releasing hormone (gnrh) plays essential roles in embryo implantation, invasion of trophoblastic tissue, and steroid synthesis in the placenta. objective: the aim of this study was to evaluate the effect of gnrh antagonist administration on pregnancy outcomes in early implantation period. materials and methods: in this retrospective study, 94 infertile women undergoing ...

BACKGROUND Corticotrophin releasing hormone (CRH) is believed to mediate stress-induced behaviors, implying a broader, integrative role for the hormone in the psychological stress response, and studies on CRH in physical stress are few. This study was undertaken to investigate whether CRH plays an important role in cerebral infarction-related gastrointestinal barrier dysfunction. METHODS Thir...

Stress can inhibit maternal behaviour and increase rates of child abuse in humans and other animals; however, the neuroendocrine mechanisms are not known. To determine whether corticotrophin-releasing hormone (CRH) plays a role in stress-induced disruption of maternal behaviour in primates, we characterised the effects of acute i.c.v. infusions of CRH on maternal and abusive behaviour in common...
