diabetes mellitus is a group of metabolic diseases. insulin resistance is defined as a state that needs more insulin to get the biological effects achieved by a lower amount of insulin in the normal state. several molecules which are secreted through adipocytes have been involved in insulin resistance and type 2 diabetes mellitus. adiponectin as a 244 amino acid protein is exclusively expressed...

In this study, the effects of late gestational undernutrition (LGU) on plasma concentration of insulin-like growth factor 1 (IGF-I), leptin, insulin and glucose in subsequent sucking lambs was investigated. Ten twin-bearing ewes were fed either restrictedly (Restricted) or adequately (Control) during the last six weeks of gestation and were fed ad libitum after parturition. Blood samples were t...

Specific insulin-like growth factor I (IGF-I) receptors on the Madin-Darby canine kidney (MDCK) cell line were identified and characterized. [125I]IGF-I specifically bound to the cells, but [125I]insulin bindings to the cells was minimal. Unlabeled IGF-I displaced both the IGF-I and insulin bindings with potencies that were 100 and 10 times as great as insulin. By an affinity labeling technique...

Background: Data on safety degree and anti–type 1 diabetic effects of Pterocarpus soyauxii Taub are known, but not type 2 diabetes yet. Objective: To evaluate preventive P. aqueous stem bark extract dexamethasone–induced insulin resistance oxidative stress in rat. Materials Methods: Glucose-overloaded normal Wistar rats were administered with plant at various doses (38–300 mg.kg) a si...

OBJECTIVE Defects in insulin secretion and insulin action are the major abnormalities in the development of type 2 diabetes. In middle-aged subjects, elevated plasma proinsulin has been found to predict type 2 diabetes. Therefore, our aim was to study the longitudinal relationships between baseline determinations of insulin sensitivity index (S(i)) assessed by euglycemic insulin clamp, the earl...

We have prepared by semisynthetic methods a two-chain insulin/insulin-like growth factor I hybrid that contains a synthetic peptide related to residues 22-41 of insulin-like growth factor I linked via peptide bond to ArgB22 of des-octapeptide-(B23-B30)-insulin and have applied the analog to the analysis of ligand interactions with the type I insulin-like growth factor and insulin receptors of p...

The mechanism underlying the handling of protein and peptide drugs such as insulin in alveolar epithelial cells is still unclear. We therefore examined fluorescein isothiocyanate-labeled (FITC)-insulin uptake in rat primary cultured alveolar type II epithelial cells and in transdifferentiated type I-like cells. FITC-insulin uptake in these cells was much higher than those of FITC-immunoglobulin...

â  â  background a substantial proportion of the mortality in patients with type 2 diabetes mellitus (t2dm) is related to non-alcoholic fatty liver disease (nafld) and its complications. insulin resistance is a major etiologic factor for the development of fatty liver. we aimed to study the prevalence of nafld among t2dm patients and its relation to insulin resistance. methods patients with t2d...
