objective: serum leptin concentration reflects the body fat mass. there is controversial reports about the insulin effect on serum leptin concentration. we wanted to examine the effect of insulin therapy on serum leptin in children with new onset type i diabetes. materials and methods: this was a cross-sectional study in children's medical center on 34 children who had new onset type i dia...

abstract introduction: there is limited knowledge available on the metabolism of glucose in the brain, an insulin insensitive organ. insulin receptors hybridize with insulin like growth factor receptor (igf-i) to transduce the signals in different areas of the brain. in this article we aimed at investigating whether the expression of igf-i receptor and igf-i binding proteins (igfbp1) is changed...

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...

background: resistin and ghrelin are hormones that have roles in the glucose and lipid homeostasis and weight regulation. human studies regarding resistin and ghrelin in diabetic patients are scarce, especially in the cases of normotensive and non-obese patients. this study was designed to illuminate some of the missing points.methods: eighty diabetic patients and eighty healthy individuals par...

conclusions it seems that in people with type 2 diabetes, acute aerobic exercise can decrease the plasma levels of glucose, possibly through increasing orexin a. in addition, negative energy balance is necessary to decrease the levels of insulin and insulin resistance during acute aerobic exercise. results the analysis of findings in p ≤ 0.05 indicated that acute aerobic exercise caused a signi...
