introduction: adenotonsillar hypertrophy (ath) may present with growth retardation. insulin-like growth factor 1 (igf-1) mediates the anabolic effects of growth hormone (gh) on tissues. most of the circulating igf-1 molecules are bound to insulin-like growth factor-binding protein 3 (igfbp-3). igf-1 and igfbp-3 serum levels reflect the levels of daily mean serum gh and are used as indices for e...

background: the aim of this study was to evaluate whether higher serum levels of insulin-like growth factor-i (igf-i) in the acute phase of ischemic stroke are associated with less severe strokes and better functional outcome in a period of 12-month follow-up. methods: from october 2014 to august 2015, patients with the diagnosis of acute ischemic stroke admitted to the stroke unit of firoozgar...

background a fall in plasma concentration of energy status related hormones (leptin, insulin-like growth factor-1 (igf-1) and insulin) and body energy expenditure occurs in response to short term fasting. nevertheless, the relations of the fasting-induced changes in energy related hormones and metabolites with fasting energy expenditure (fee) under extended fasting condition have received littl...

background:  the aim of this study was to evaluate whether higher serum levels of igf-i in the acute phase of ischemic stroke are associated with less severe strokes and better functional outcome in a period of one year follow up. methods: from october 2014 to august 2015, patients with the diagnosis of acute ischemic stroke admitted to the stroke unit of firoozgar hospital entered this prospec...

results 100 patients with cirrhosis with a male to female ratio of 63:37 and a mean age of 44.4 ± 15 years were enrolled in the study. median igf-1 was 92.95 ± 91.51 ng/ml. 14 patients (14%) had igf-1 within normal limits while 86 patients (86%) had abnormal igf-1 levels. in all patients the correlation coefficient between igf-1 and meld was -0.317 (p = 0.001) and 0.478 between igf-1 and child-...

the insulin-like growth factor i receptor (igf-ir) plays an essential role in the establishment and maintenance of transformed phenotype. interference with the igf-ir pathway by antisense causes reversal of the transformed phenotype in many rodent and human tumor cell lines. we stably transfected the pc-3 human prostate cancer cell line with an igf-ir antisense rna expression plasmid. the numbe...

baluchi sheep is considered as the most common breed in iran, constituting about 30% of total sheep population, approximately 15 million heads. this research was designed to study the incidence of mutation in two loci of igf-i (exon 3) and adrb3 (intron) along with their association with body weight traits in baluchi sheep population. following dna extraction from 190 baluchi sheep, two pairs o...

Dietary components responsible for the regulation of somatomedin-C in humans were assessed in five adult volunteers of normal weight who were fasted for 5 d on three occasions, then refed three diets of differing composition. The serum somatomedin-C decreased from a mean prefasting value of 1.85 +/- 0.39 U/ml (+/- 1 SD) to 0.67 +/- 0.16 U/ml at the end of fasting (P less than 0.005). After refe...
