Obesity is an important factor that threatens human health. The occurrence of many chronic diseases related to obesity, and cognitive function decline often occurs with the onset obesity. With further prevalence it bound lead a wider range dysfunction (ORCD). Therefore, crucial suppress ORCD through intervention. In this regard, exercise has been shown be effective in preventing obesity improvi...

Insulin-like growth factor-1 (IGF-1) plays a central role in cellular growth, differentiation, survival, and cell cycle progression. It is expressed early during development and its effects are mediated through binding to a tyrosine kinase receptor, the insulin-like growth factor-1 receptor (IGF-1R). In the circulation, the IGFs bind to IGF-binding proteins (IGFBPs), which determine their bioav...

Polymeric tissue engineering scaffolds prepared by conventional techniques like salt leaching and phase separation are greatly limited by their poor biomolecule-delivery abilities. Conventional methods of incorporation of various growth factors, proteins, and/or peptides on or in scaffold materials via different crosslinking and conjugation techniques are often tedious and may affect scaffold's...

Insulin-like growth factor (IGF)-1 is a well characterized growth factor that plays a role in the regulation of myocardial structure and function. Using an ex vivo murine model, Davani and coworkers, in this issue of Critical Care, demonstrate that IGF-1 confers cardiac protection against ischemia via mitochondria-dependent mechanisms. Those investigators used the ratio of mitochondrial to nucl...

The insulin-like growth factor I receptor (IGF-IR) belongs to the family of transmembrane tyrosine kinase receptors, like the receptors for platelet-derived growth factor, the epidermal growth factor, insulin, and others. Genetic evidence has shown that the IGF-IR is required for optimal growth in vitro and in vivo. Even more important, however, have been recent findings from several laboratori...

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...

Introduction: Biochemical markers play an important role in the growth and repair of bone and can be evaluated in different biological fluids. Therefore, the aim of this study was to evaluate the level of insulin-like growth factor-I (IGF-I) in urine as a puberty index and to compare it with cervical vertebral maturational stages (CVMSs) in lateral cephalometry. Materials&Methods: In this cros...

The development of a homologous RIA for chicken insulin-like growth factor-II (cIGF-II) and its application to investigate the developmental changes in IGF-II in the chicken and turkey are described. A double-antibody RIA has been developed using recombinantly derived cIGF-II as antigen, radiolabelled tracer and standard. Serial dilutions of chicken and turkey plasma were parallel to serial dil...

The type I insulin-like growth factor receptor (IGF-IR) is known to send two seemingly contradictory signals inducing either cell proliferation or cell differentiation, depending on cell type and/or conditions. H19-7 cells are rat hippocampal neuronal cells immortalized by a temperature-sensitive SV40 large T antigen that grow at 34 degrees C in epidermal growth factor or serum but differentiat...
