BACKGROUND The combination of the independent risk factors for erectile dysfunction, obesity, hypertension, and diabetes are manifested collectively in a condition known as metabolic syndrome X. However, the exact mechanism(s) by which the combination of these factors contributes to erectile

Increased oxidative stress is a known cause of cardiac dysfunction in animals and patients with diabetes, but the sources of reactive oxygen species [e.g., superoxide anion (O(2)(-))] and the mechanisms underlying O(2)(-) production in diabetic hearts are not clearly understood. Our aim was to

Resistin, an adipocyte-derived hormone, is thought to represent a link between obesity and insulin-resistant diabetes. The potential role of resistin as a cardioprotective agent has not been explored. Our hypothesis is that resistin has a cardioprotective effect that is mediated by the resistin

Leptin, a product of the ob gene, decreases food intake and body weight in both Wistar and Zucker obese rats when administered centrally or peripherally. To examine whether these leptin effects might be mediated through a neuropeptide Y (NPY) signaling pathway in the medial part of the arcuate
