BACKGROUND Angiogenesis plays an important role in the mechanism of diabetic retinopathy (DR). Visfatin, a recently identified adipokine, is thought to possess an angiogenic effect. The aim of our study was to investigate serum and vitreous levels of visfatin in patients with proliferative diabetic retinopathy (PDR) and non-PDR (NPDR). MATERIAL AND METHODS A total of 280 diabetic patients (12...

BACKGROUND Visfatin is an intracellular enzyme, known as nicotinamide phosphoribosyltransferase (Nampt) and pre-B-cell colony-enhancing factor (PBEF-1). It has insulin-mimetic effects and lowers plasma glucose levels. AIM The aim of the work was to assess serum concentration of Visfatin in type 1 diabetic children and adolescents and study its relationships with duration of diabetes, body mas...

OBJECTIVE To evaluate the effect of prolonged intensive aerobic exercise and acute energy deficit (180 km ultra-marathon race) on serum leptin, adiponectin, resistin and visfatin levels and their association and interaction with serum cortisol and insulin levels in highly trained ultra-endurance runners. DESIGN The study included 17 highly trained ultra-endurance male athletes (mean age 51.29...

PURPOSE Visfatin is an adipocytokine involved in cellular metabolism, inflammation, and cancer. This study investigated the roles of extracellular visfatin in breast cancer, and explored underlying mechanisms in clinical and experimental settings. EXPERIMENTAL DESIGN Associations of serum visfatin with clinicopathologic characteristics and patient survival were assessed with Cox regression mo...

Visfatin has been proposed as an insulin-mimicking adipocytokine, predominantly secreted from adipose tissue and correlated with obesity. However, recent studies suggest visfatin may act as a proinflammatory cytokine. Our studies sought to determine the significance of this adipocytokine and its potential role in the pathogenesis of T2DM. Firstly, we examined the effects of diabetic status on c...

polycystic ovary syndrome (pcos) is a common endocrine / metabolic disorder in women of reproductive age .abdominal adiposity and obesity are frequently present in pcos. it now appears that, obesity is associated with a low-grade inflammation of white adipose tissue. adipokines play a significant role in the pathogenesis of a low-grade inflammation associated with obesity. among variety of adip...

THE ASSOCIATION OF ADIPOKINES AND INSULIN RESISTANCE IN WOMEN WITH POLYCYSTIC OVARIAN SYNDROME Thesis under the direction of Gary D. Miller, PhD., Associate Professor of Health and Exercise Science. A metabolic disorder with increasing concern to premenopausal women is Polycystic Ovarian Syndrome (PCOS). PCOS leads to numerous health-related concerns, including insulin resistance. The cause of ...

Adipocytokines, hormones secreted from adipose tissue, have been shown to be associated with many cancers such as breast, prostate and colorectal cancer. Recent studies have indicated that resistin and visfatin, two of these adipokines have high level plasma concentrations in colorectal cancer patients and may be promising biomarkers for colorectal cancer. The aim of this study was to identify ...

OBJECTIVE Recent studies, both in vitro and in vivo, have indicated that visfatin is one of the inflammatory cytokines, although the relationship between visfatin and insulin resistance remains inconclusive. Accordingly, we assessed the association between visfatin concentrations in serum and those of interleukin-6 (IL-6) and C-reactive protein (CRP), known as markers of systemic inflammation, ...
