Nitric oxide (NO) is thought to play an important role as an inhibitor of vascular cell proliferation, motility, and neointima formation. This effect is mediated, in part, via the upregulation of protein tyrosine phosphatase (PTP)1B. Conversely, studies have reported that in presumably hyperinsulinemic mice fed a high-fat diet, NO enhances ...

The aim of this study was to establish a rehabilitation program (pharmacological and physical) focused not only on ...

Insulin, a 51-residue peptide hormone, is an intrinsically amyloidogenic peptide, forming amyloid fibrils in vitro. In the secretory granules, insulin is densely packed together with Zn(II) into crystals of Zn(2)Insulin(6) hexamer, which assures osmotic stability of vesicles and prevents fibrillation of the peptide. However, after release from the pancreatic beta-cells, ...

Participants were 25 872 men and 33 919 women aged 45-75 years who had no history of diabetes. Magnesium intake was ascertained using a 147-item food frequency questionnaire. Odds ratio of self-reported physician-diagnosed type II diabetes ...

Diabetes is a chronic disease requiring continuous medical supervision and patient education to prevent acute secondary complications. In this study, we have harnessed the inherent property of insulin to aggregate into an oligomeric intermediate on the pathway to amyloid formation, to generate a form that exhibits controlled and sustained release ...

BACKGROUND: C-reactive protein is an acute-phase proteins, produce in the liver, its release is stimulated by cytokines (interleukin 6 and tumour necrosis factor alpha). Elevated level of it is a risk factor for coronary heart disease. Baseline levels of C-reactive protein in apparently healthy men and women predict long-term risk ...

Insulin resistance is an underlying mechanism of type 2 diabetes and its vascular complications. Recent evidence suggests that crosstalk between angiotensin II (Ang II) and the insulin signaling in vascular smooth muscle cell (VSMC) may contribute to cellular insulin resistance. We hypothesized that Ang II inhibits the anti-mitogenic pathways while ...
