in this study escherichia coli de3 containing expression vector (pet21a) with cloned persian sturgeon growth hormone (psgh) gene was grown in 10 ml lb broth on a 150 rpm shaker, at the temperature of 37 °c. at the late log phase (determined by od standard curve) 100 μl isopropyl β-d-1-thiogalactopyranoside (iptg) was added for induction of gh synthesis. samples were taken every 2 hours and afte...

Resistance to thyroid hormone is an uncommon condition. We report the clinical and laboratory findings of a case with both resistance to thyroid hormone and, a reduced capacity to produce and respond to thyroid hormone. RTH is a disorder characterized by elevated circulating thyroid hormones, state of non-suppressed pituitary TSH secretion and refractoriness to hormone action in peripheral tiss...

Subcutaneous Parathyroid Hormone in ADH1 In this letter, the investigators report that continuous subcutaneous infusion of parathyroid hormone (1-34) six patients who were between ages 5 ...

This study investigated the effects of five levels of galanin on plasma concentrations of growth hormone, triiodothyronine, thyroxine, and milk protein in dairy goat breed was sannan. 15 breeds of dairy goats sannan all about the same age and weight were selected for this study and were randomly divided into five treatments (three replicates per treatment). Levels of the hormone injection of ga...

introduction: ghrelin increases growth hormone secretion and food intake. growth hormone (gh), steroid hormones and opioids are involved in the regulation of food intake. so, they may have a role in the regulation of ghrelin secretion. we determined the effect of intravenous injections of progesterone, gh and morphine or co-administration of these hormones on ghrelin concentration and body weig...

background:   objective: the purpose of this cross-sectional study was assessment of dose-response relationship between blood lead level (bll) and sex hormones levels in lead exposed male workers.   materials and methods: one hundred and thirteen male workers enrolled. all workers had at least 6 months of lead exposure and no history of diseases or conditions affecting reproductive system. bloo...

the growth hormone gene could be an attractive candidate gene for milk production in goats. single-strand conformation polymorphism was used to identify polymorphism at the goat growth hormone (ggh) gene. for this purpose, genotyping of 90 talli goat breeds was performed. nine conformational patterns were observed in exon 4 of the ggh gene, with frequencies of 27.7% for the homozygous pattern (...

background: natural endometrium in frozen-thawed embryo transfer (fet) may have some benefits upon implantation in patients with repeated implantation failure (rif). it might be due to possible differences between natural and stimulated endometrial growth factors and cytokins secretions. objective: the objective of this study was to compare the pregnancy rate of fet on modified natural cycle ve...

Background: To evaluate whether success of fertilization and embryo quality are more probable when follicular fluid Anti-mullerian hormone levels are higher . Materials and Methods: 62 women who underwent IVF cycle were divided into fertilized oocytes group (n=42) and non- fertilized oocytes group (n=20) . Follicular fluid Anti-mullerian hormone levels were measured in both groups. Results: Ant...
