CONTEXT Visfatin (also known as pre-B cell colony-enhancing factor or PBEF) is a cytokine that is highly expressed in visceral fat and whose blood levels correlate with obesity. Originally isolated as a secreted factor that promotes the growth of B cell precursors and recently found to act as an insulin analog on the insulin receptor, its pathophysiological role in humans remains largely unknow...

Liver cirrhosis is a catabolic disease associated with a high incidence of insulin resistance and diabetes mellitus. Pre-B cell colony-enhancing factor/ nicotinamide phosphoribosyltransferase/visfatin has been characterized as a novel adipokine with a potential role in glucose metabolism and nicotinamide dinucleotide (NAD) generation. We studied plasma levels and metabolic relevance of visfatin...

The purpose of this study was to assess differences in the levels of plasma visfatin among female adolescents and changes in plasma visfatin and insulin resistance in obese female adolescents after 12 wk of aerobic exercise training. Twenty normal-weight female students (body-mass index [BMI] < 22.9 kg/m² and body fat ≤ 29.9) and 18 obese female students (BMI ≥ 25 kg/ m² and body fat ≥ 30%) par...

BACKGROUND Extra-lipid effects of ezetimibe, a new lipid-lowering agent, are so far poorly understood. METHODS Twenty-two patients with elevated total and LDL cholesterol levels, statin-intolerant or having contraindications to statin therapy, were treated with ezetimibe (10mg daily) for 90 days. Plasma levels of lipids, apolipoproteins, glucose homeostasis markers, leptin, adiponectin, visfa...

INTRODUCTION Visfatin is an adipokine secreted by visceral adipose tissue with insulin-mimetic properties. Higher circulating visfatin levels were reported in type 2 diabetes. The aim of this study was to analyse circulating visfatin and insulin levels and the visfatin/insulin ratio in obese women with and without metabolic syndrome (MetS). MATERIAL AND METHODS The study involved 92 obese wom...

Objective. The aim of the study was to analyze the association between levels of adipokines in the breast cyst fluid and in the circulation in relation to the type of cysts. Material and Measurements. A cross-sectional study involved 86 women with breast cysts (42 with simple cysts and 44 with complex cysts). Plasma and breast cyst fluid leptin, adiponectin, visfatin/NAMPT, resistin, TNF-α, and...

Abtract Introduction: Visfatin is a newly discovered adipokine which is highly expressed in visceral adipose tissue that may induces changes in insulin resistance. The Aim of this study was to examine the Effect of Endurance Exercise on Visfatin and Insulin Levels In Obese Women. Method: present research is a semi-empirical study that 10 obese female volunteers (age 35.6±7.12 y, body mass in...
