Growth hormone (GH) and insulin-like growth factor 1 (IGF-1) are the most important regulators of growth, regeneration metabolism. The influence GH IGF-1 on pediatric liver transplant outcomes is mediated through body weight regulation, specific effects hepatocyte function immune system activity. In recent years, blood levels these factors life expectancy, both in healthy individuals recipients...
Introduction: In recent years, a number of researches have been carried out regarding the relationship between atherosclerosis and serum levels of GH and IGF-1 and different results were obtained. This study aimed to determine the effect of a six-month aerobic exercise on levels of GH, IGF-1 and GH/IGF-1 ratio serum in sedentary middle-aged women Methods: Nineteen healthy females, who were sel...
Background & Objective: To find an association between gene variants of insulin-like growth factor-1 (IGF-1) and 5,10-methylenetetrahydrofolate reductase (MTHFR) with the risk of acne vulgaris (AV). Methods: In a case-control study, we investigated 150 AV patients and 148 healthy individuals (aged 18-25 years) for the IGF-1 G>A and MTHFR C677T polymorphis...
مقدمه: در سال های اخیر تحقیقاتی در مورد رابطه آترواسکلروز و سطح سرمی ghو igf-1 انجام شده و نتایج متفاوتی به دست آمده است. هدف از اجرای این پژوهش بررسی اثر شش ماه تمرین هوازی بر غلظت هورمون رشد، igf-1 و نسبت gh به igf-1 سرمی زنان میانسال غیرفعال بود. روش بررسی: در این تحقیق 19 آزمودنی در دو گروه تجربی (11 نفر) و کنترل (8 نفر) به روش نمونه گیری در دسترس و هدفمند انتخاب شدند. آزمودنی ها به مدت 6 م...
در سالهای اخ?ر مطالعه ی ژنهای کاند?دا ?عن? ژن های توال??اب? شده ای که فعال?ت ب?ولوژ?ک? آن ها شناخته شده است و در تکامل ?ا ف?ز?ولوژی صفات مورد نظر دخالت دارند، توسط تعداد ز?ادی از محقق?ن مورد توجه بوده است. فاکتور رشد شبه انسولین نوع ? یا همان سوماتومدین c بیشتر در کبد و دیگر بافت ها تحت تاثیر هورمون رشد سنتز می شود. این ژن در رشد و نمو سلول ها و بسیاری از فرآیند های فیزیولوژیک بدن مانند تولید م...
Non-islet cell tumor hypoglycemia (NICTH) is a rare paraneoplastic syndrome in which secretes high molecular weight (“big”) IGF-2, causing hypoglycemia. Big IGF-2 product of abnormal processing precursors with defective gene transcription and expression. Tumors involved are usually mesenchymal, vascular, or epithelial origin have burden. We report an unusual case NICTH patient concomitant spind...
Objective(s): The aim of the present study was to investigate the effects of genistein and exercise on the spatial memory and expression of microRNA-132, BDNF, and IGF-1 in the hippocampus of ovariectomized rats. Materials and Methods: Sixty animals were divided into six groups of control, sham, ovariectomy (OVX), ovariectomized with 8 weeks of genistein administration (OVX.G), with 8 weeks of ...
Background: Diabetes is a common endocrine disease in human kind. In most type II diabetic patients, obesity and overweight status account as the serious health problems worldwide and variety of endocrine factors well known that have regulatory role in weight balance and body composition including Leptin and IGF-I factor. The aim of this study was to examine the correlation between Leptin and I...
Background and Objective: Studies have shown that insulin-like growth factor (IGF-I) is the main factor of growth and hypertrophy of muscle fibers. However, the effect of high-intensity interval training (HIIT) on IGF-I has not been well studied. The purpose of the present study was to investigate the changes of IGF-I gene expression in gastrocnemius muscle of male Wistar rats after a period of...
Background: Morphine is wildly used as a painkiller in clinics, but causes several side effects such as hyperalgesia, depression and more notably amnesia. Here, we assumed that insulin-like Growth Factor-1 (IGF-1) as a peptide with widespread distribution of receptors in brain regions, especially hippocampus, might be capable to alleviate morphine-induced amnesia. Meth...
