background: leptin and adiponectin are the two key metabolic hormones secreted from adipocytes to control food intake and energy expenditure. the action of both hormones in regulation of gonadotropin releasing hormone (gnrh) secretion from the hypothalamus is mediated through kisspeptins. kisspeptins are products of kiss-1 gene. leptin and adiponectin are modulators of kiss-1 expression in the ...

background:   objective: this study was designed to evaluate effects of lithium chloride on the release of steroid hormones and steroidogenic enzymes in gonadotropin-stimulated rats.   materials and methods: immature 23 days old wistar rats were divided into 10 groups; each group comprised of 8 rats, and induced with single injection of pregnant mare’s serum gonadotrophin (pmsg) and followed by...

A full-length transcript encoding a functional lamprey glycoprotein hormone receptor I (lGpH-R I, GenBank AY750688) was cloned from the testes of the sea lamprey, Petromyzon marinus, using the GpH-R protein fingerprint GLYCHORMONER from the PRINTS database. The present study is the first to identify a GpH-R transcript in an agnathan, which is one of the only two representatives of the oldest li...

Background: Human chorionic gonadotropin (hCG) is a member of glycoprotein hormones family consist of two different non-covalently heterodimeric chains: alpha and beta subunits with 92 and 145 amino acids respectively. This hormone plays an important role in human reproduction and physiology especially for maintenance of the corpus luteum during the first months of pregnancy Materials and Metho...

 Materials methods. To solve tasks, we conducted a study 60 pregnant women (the main group) with dysfunction. control group consisted 30 physiological course pregnancy, who gave birth live full-term children weight growth characteristics according gestation period. state fetoplacental com...

The common palm civets (Paradoxurus hermaphroditus) belong to the family (Viverridae), carnivores order (Carnivora). This animal is widely distributed in South and Southeast Asia. Currently, are raised quite popular Vietnam. delay breeding for first time slow rut has reduced economic efficiency civet farming. study was carried out evaluate effectiveness of different doses hormones (PMSG, HCG) o...

background: the pattern of islamic fasting differs from other forms of fasting, therefore its effect on health also differs. this research studies the effect of islamic fasting on gonadotropin hormones around the time of the ovulatory cycle and ovulation. materials and methods: this self-controlled study was performed on 24 adult females. blood sampling was performed during ramadan and two mont...

Historically, insulin resistance during pregnancy has been ascribed to increased production of placental hormones and cortisol. The purpose of this study was to test this hypothesis by correlating the longitudinal changes in insulin sensitivity during pregnancy with changes in placental hormones, cortisol, leptin, and tumor necrosis factor (TNF). Insulin resistance was assessed in 15 women (5 w...
