The Sick Adipose Tissue: New Insights Into Defective Signaling and Crosstalk With the Myocardium.

Adipose tissue (AT) biology is linked to cardiovascular health since obesity is associated with cardiovascular disease (CVD) and positively correlated with excessive visceral fat accumulation. AT signaling to myocardial cells through soluble factors known as adipokines, cardiokines, branched-chain amino acids and small molecules like microRNAs, undoubtedly influence myocardial cells and AT function the endocrine-paracrine mechanisms of action. Unfortunately, abnormal total and visceral adiposity can alter this harmonious signaling network, resulting in tissue hypoxia and monocyte/macrophage adipose infiltration occurring alongside expanded intra-abdominal and epicardial fat depots seen in the human obese phenotype.

The Role of the α Cell in the Pathogenesis of Diabetes: A World beyond the Mirror.

Type 2 Diabetes Mellitus (T2DM) is one of the most prevalent chronic metabolic disorders, and insulin has been placed at the epicentre of its pathophysiological basis. However, the involvement of impaired alpha (α) cell function has been recognized as playing an essential role in several diseases, since hyperglucagonemia has been evidenced in both Type 1 and T2DM. This phenomenon has been attributed to intra-islet defects, like modifications in pancreatic α cell mass or dysfunction in glucagon's secretion.

Stevia rebaudiana Bertoni and Its Effects in Human Disease: Emphasizing Its Role in Inflammation, Atherosclerosis and Metabolic Syndrome.

Purpose Of Review: Stevia rebaudiana Bertoni is a perennial shrub with zero calorie content that has been increasing in popularity for its potential use as an adjuvant in the treatment of obesity. The level of evidence supporting general benefits to human health is insufficient. We conducted a review of the literature summarizing the current knowledge and role in human disease.

Ciprofibrate treatment decreases non-high density lipoprotein cholesterol and triglycerides and increases high density lipoprotein cholesterol in patients with Frederickson type IV dyslipidemia phenotype.

Objective: The combination of hypertriglyceridemia and low high density lipoprotein (HDL) cholesterol is one of the most common lipid abnormalities. Thus, the aim of this study was to determine the effects of ciprofibrate on lipid profile in patients with Frederickson's type IV dyslipidemia phenotype.

Research Design And Methods: Seventy-five patients with type IV dyslipidemia were assigned at random to 1 of 2 therapeutic options: group A (control), American Heart Association (AHA) Step II diet and physical activity; and group B, AHA diet, physical activity, and ciprofibrate 100 mg daily for 8 weeks.

[Malondialdehyde and reduced glutathione increase in patients with chronic stable ischaemic cardiopathy].

Background And Objective: Cardiovascular diseases are associated with the ischemia/reperfusion phenomena and therefore to the oxidation/antioxidation balance. The aim of this study was to determine malondialdehyde, nitric oxide, glutathione, ascorbic and dehydroascorbic acid in patients with chronic ischemic heart disease.

Patients And Method: 32 male patients, with chronic ischemic heart disease, between 40 and 60 years of age were studied.
