BACKGROUND: Long term endurance training, as occurring in elite athletes, is associated to cardiac neural remodeling in favor of cardioprotective vagal mechanisms, resulting in resting bradycardia and augmented contribution of cardiac parasympathetic nerve activity. Autonomic assessment can be performed by way of Heart Rate Variability. This technique however provides multiple indices, and there is not yet complete agreement on their specific significance. Purpose of the study was to assess whether a rank transformation and radar plot could provide a unitary autonomic index, capable to show a correlation between intensity of individual work and quality of autonomic regulation...

Lipoprotein lipase (LPL) hydrolyzes lipids in plasma lipoproteins so that the fatty acids can be taken up and used by cells. The activity of LPL changes rapidly in response to changes in nutrition, physical activity and other conditions. Angiopoietin-like protein 4 (ANGPTL4) is an important controller of LPL activity. Both LPL and ANGPTL4 are produced and secreted by adipocytes. When the transcription blocker Actinomycin D was added to cultures of 3T3-L1 adipocytes, LPL activity in the medium increased several-fold...

Small heterodimer partner (SHP) is an atypical nuclear receptor expressed in heart that has been shown to inhibit the hypertrophic response. Here, we assessed the role of SHP in cardiac metabolism and inflammation. Mice fed a high-fat diet (HFD) displayed glucose intolerance accompanied by increased cardiac mRNA levels of Shp. In HL-1 cardiomyocytes, SHP overexpression inhibited both basal and insulin-stimulated glucose uptake and impaired the insulin signalling pathway (evidenced by reduced AKT and AS160 phosphorylation), similar to insulin resistant cells generated by high palmitate/high insulin treatment (HP/HI; 500μM/100nM)...

Cardiovascular disease is the leading cause of death in the world. Dyslipidemia, manifested by elevated low-density lipoprotein cholesterol (LDL-C) levels, is central to the development and progression of atherosclerosis. Dyslipidemia has become a primary target of intervention in strategies for the prevention of cardiovascular events. Therapeutic lifestyle changes, such as increased physical activity, weight loss, smoking cessation, and adoption of a healthier diet, are effectively reducing cardiovascular risk in primary and secondary prevention...

BACKGROUND: In rheumatoid arthritis (RA), cardiovascular risk is associated with paradoxical reductions in total cholesterol, low density lipoprotein-cholesterol (LDL-C), and high density lipoprotein-cholesterol (HDL-C). Concentrations of small LDL (LDL-P) and HDL (HDL-P) particles are also reduced with increased inflammation and disease activity in RA patients. Here we sought to identify which measure(s) of inflammation, disease activity and cardiometabolic risk contribute most to the RA-associated lipoprotein profile...

OBJECTIVE: Phosphatidylcholine transfer protein (PC-TP; synonym StarD2) is highly expressed in liver and oxidative tissues. PC-TP promotes hepatic glucose production during fasting and aggravates glucose intolerance in high fat fed mice. However, because PC-TP also suppresses thermogenesis in brown adipose tissue (BAT), its direct contribution to obesity-associated diabetes in mice remains unclear. Here we examined the effects of genetic PC-TP ablation on glucose homeostasis in leptin-deficient ob/ob mice, which exhibit both diabetes and altered thermoregulation...

BACKGROUND: Repeated stress paradigms have been shown to cause devastating alterations on memory functions. Stress is linked with inflammation. Psychological and certain physical stressors could lead to neuroinflammation. Inflammatory process may occur by release of mediators and stimulate the production of prostaglandins through cyclooxygenase (COX). Treatment with COX inhibitors, which restrain prostaglandin production, has enhanced memory in a number of neuroinflammatory states showing a potential function for raised prostaglandins in these memory shortfalls...

The VI European Guidelines for Cardiovascular Prevention recommend combining population and high-risk strategies with lifestyle changes as a cornerstone of prevention, and propose the SCORE function to quantify cardiovascular risk. The guidelines highlight disease specific interventions, and conditions as women, young people and ethnic minorities. Screening for subclinical atherosclerosis with noninvasive imaging techniques is not recommended. The guidelines distinguish four risk levels (very high, high, moderate and low) with therapeutic objectives for lipid control according to risk...

Previous studies have shown that serum zinc and adiponectin levels are associated with insulin resistance in the polycystic ovary syndrome (PCOS) patients. But there is no study to evaluate serum zinc and adiponectin levels as predictor markers of PCOS, adjusted for anthropometric, biochemical, dietary intake, and physical activity measures. Ninety-one new PCOS cases (based on the Rotterdam criteria) and 85 healthy control women participated and individually matched based on age. Food intake of all participants obtained by the food frequency and physical activity level was assessed by the International Physical Activity Questionnaires...

Respiratory syncytial virus (RSV) is an enveloped virus that assembles into filamentous virus particles on the surface of infected cells. Morphogenesis of RSV is dependent upon cholesterol-rich (lipid raft) membrane microdomains, but the specific role of individual raft molecules in RSV assembly is not well defined. Here we show that RSV morphogenesis occurs within caveolar membranes and that both caveolin-1 and cavin-1, the two major structural and functional components of caveolae, are actively recruited to and incorporated into the RSV envelope...
