EGCG, a green tea polyphenol, improves endothelial function and insulin sensitivity, reduces blood pressure, and protects against myocardial I/R injury in SHR.
Epigallocatechin gallate (EGCG), a bioactive polyphenol in green tea, may augment metabolic and vascular actions of insulin. Therefore, we investigated effects of EGCG treatment to simultaneously… Expand

Endothelin-1: the yin and yang on vascular function.
Endothelin-1 (ET-1) is a vasoconstrictor secreted by endothelial cells, which acts as the natural counterpart of the vasodilator nitric oxide (NO). ET-1 contributes to vascular tone and regulates… Expand

Endothelial dysfunction in diabetes: from mechanisms to therapeutic targets.
Micro- and macrovascular complications are major causes of disability and death in patients with diabetes mellitus. Functional impairment of endothelial activity precedes the development of… Expand

Insulin resistance in spontaneously hypertensive rats is associated with endothelial dysfunction characterized by imbalance between NO and ET-1 production.
Insulin stimulates production of NO in vascular endothelium via activation of phosphatidylinositol (PI) 3-kinase, Akt, and endothelial NO synthase. We hypothesized that insulin resistance may cause… Expand

Vascular actions of insulin with implications for endothelial dysfunction.
Hemodynamic actions of insulin depend largely on the hormone's ability to stimulate synthesis and release of endothelial mediators, whose balanced activity ensures dynamic control of vascular… Expand

Hyporeactivity of mesenteric vascular bed in endotoxin-treated rats.
Vascular reactivity and activation of the nitric oxide (NO) pathway were investigated in perfused mesenteric vascular bed removed from rats 5 h after i.p. injection of bacterial lipopolysaccharide… Expand

Immunoregulatory effects of L-arginine and therapeutical implications.
Arginine, initially classified as a non-essential amino acid, participates to multiple biological processes including release of several hormones, collagen synthesis during wound healing, antitumor… Expand

Treatment of Spontaneously Hypertensive Rats With Rosiglitazone and/or Enalapril Restores Balance Between Vasodilator and Vasoconstrictor Actions of Insulin With Simultaneous Improvement in…
Spontaneously hypertensive rats (SHRs) exhibit endothelial dysfunction and insulin resistance. Reciprocal relationships between endothelial dysfunction and insulin resistance may contribute to… Expand

Neurofunctional effects of developmental sodium fluoride exposure in rats.
Contrasting studies on the toxic effects of sodium fluoride (NaF) during developmental stages of Wistar rats, lead us to investigate the neurofunctional effects caused by its perinatal exposure,… Expand
