Objective: This study examined the effect of high intensity interval training (HIIT) on HNF-4α gene expression, glucose and insulin in liver tissue of type 2 diabetic male Wistar rats. Materials and Methods: In this study, 20 male Wistar rats weighing 220 (±20) grams were selected. After type 2 diabetes (T2D) induction, the samples were divided into two groups of HIIT and control. The training...

Background and objectives: The role of genetic components in expression of proteins involved in signaling pathways of fat and carbohydrate metabolism has been well-demonstrated. The aim of this study was to determine effects of high intensity interval training (HIIT) on glucose, insulin, and insulin resistance levels as well as IRS1 expression in gastrocnemius muscle of obese Wistar rats. Meth...

Background: Polycystic ovary syndrome (PCOS) is an endocrine disorder and one of the main reasons of infertility in women. PCOS causes many symptoms in women, one of the most important of them is ovulation failure. It affects the women at the age of fertility. Many factors are detected to exacerbate PCOS including insulin, anti-Mullerian hormone, obesity and androgen. The aim of this study was ...

BACKGROUND/AIM Insulin sensitivity and β-cell function during Ramadan fasting in healthy male subjects have not been investigated so far. We assessed the changes of these and other metabolic parameters to judge the potential metabolic benefits of Ramadan fasting. MATERIALS AND METHODS Twenty-four healthy males of Turkish origin living in Germany, with normal glucose tolerance, participated in...

OBJECTIVE To validate fasting indices of insulin sensitivity and secretion in a diverse pediatric population against gold standard estimates from euglycemic and hyperglycemic clamps. RESEARCH DESIGN AND METHODS A total of 31 children (mean BMI 25.1 +/- 4.9 kg/m(2), mean age 8.7 +/- 1.4 years, 15 girls and 16 boys, 12 black and 19 white) underwent euglycemic and hyperglycemic clamps 2-6 weeks ...

The purpose of the present study was to evaluate the effect of Ramadan fasting on insulin sensitivity in subjects with the metabolic syndrome. Males (n 55; age 34.1 (sd 8.9) years) with the metabolic syndrome were studied. Blood pressure, waist circumference, body weight, HDL-cholesterol (HDL-C), TAG, fasting plasma glucose (FPG), fasting blood insulin and insulin resistance indices (quantitati...

Background: Substantial studies have demonstrated that fasting therapy (FT) can inhibit the inflammatory response and improve insulin resistance (IR); however, underlying mechanisms are still unclear. This study aimed to explore related of intermittent FT for treatment IR.

There is little published information on insulin levels in normal children. Ehrlich and Bambers (1964) found the fasting plasma insulin levels of 6 normal children to be similar to adult levels. Slone, Soeldner, Steinke, and Crigler (1966) have reported low fasting serum insulin levels in 13 normal children between the ages of 3 and 9 years. This paper describes the fasting immuno-reactive insu...
