background the physiological link between ghrelin and growth hormone (gh) has not yet been fully clarified. furthermore, the existence of a negative feedback mechanism between growth hormone–insulin-like growth factor (gh–igf)-i axis and ghrelin and the influence of amino acids on ghrelin secretion in children remain matters of debate. objectives to understand the regulation of ghrelin secretio...

in this article, we present the case of a 12-year-old female child who complained of bilateral temporal and frontal headache for 2 to 3 months with nausea and vomiting. physical examination revealed right-sided sixth cranial nerve palsy and papilledema in ophthalmoscopy. to find the cause of increased intracranial pressure, the patient underwent brain imaging and brain mri showed no abnormality...

human growth hormone (hgh) genomic sequence containing 5 exons and 4 introns was cloned in pcdna-3 and the constructed plasmid was subsequently used for transfection ofnlli-3t3 cell line using lipofection technique. expression of hgh in stably transfected cells was assayed using elisa. total rna was extracted from transfected cells and hgh cdna was amplified by rt-pcr using specific primers. th...

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...

introduction turner syndrome is the most common chromosomal abnormality in females. girls with turner syndrome have an abmormal or missing x choromosme that causes short stature, ovarian failure, renovascular and cardiac anomalies. it has been shown that there is a tendency to obesity in the turner syndrome. this prospective study has been done to evaluate whether body mass index (bmi) is diffe...

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...

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 (...

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...
