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...
چکیده امروزه فناوری تولید جنین آزمایشگاهی که به عنوان جدیدترین و موثرترین روش درمان ناباروری محسوب می شود، به علت عدم اطلاعات کافی از اساس مولکولی فرایند های مرتبط با آبستنی بخصوص لانه گزینی جنین در رحم، با مشکلاتی مواجه است. لانه گزینی جنین از مهم ترین مراحل تاثیر گذار در ارزیابی کیفیت جنین آزمایشگاهی تولید شده می باشد. این پدیده بیشتر تحت تاثیر عوامل هورمونی، ژنتیکی و شرایط محیط رحم قرار می...
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...
هرچند انتخاب مرسوم بر اساس ارزشهای ژنتیکی در جوجههای گوشتی موجب بهبود درسرعت رشد و بازده تولید گوشت در طی چند دهه گذشته شده است، ولی بدلیل همبستگی منفی بین صفات تولیدی و شایستگی، امروزه اصلاح نژاد در طیور با مشکل مواجه شده است. لذا انتخاب چند صفتی برای بهبود همزمان در این صفات تنها بر اساس انتخاب ژنتیکی مشکل میباشد. بنابراین انتخاب بر اساس نشانگرهای مولکولی میتواند برای افزایش بازده انتخاب ...
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: The alteration of IGF-I systemic level in diabetes is typically characterized by depletion of free IGF-I plasma level and its decreased bioavailability. With regard to protective and advantageous effects of IGF-I on tissue healing and cellular regeneration such depletion could facilitate or accelerate tissue damages and complications. By contrast, the local concentration of IGF-I i...
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...
