Cardiovascular disease (CVD) is one of the major lifestyle associated disorders and leading causes of death worldwide. The incidence of CVD in diabetic patients has increased up to 3 folds and it became the major risk for diabetes associated morbidity and mortality. Insulin resistance and oxidative stress both play a central role in the pathogenesis and progression of diabetes. The high prevalence of CVD among diabetic pa Read More

Insulin resistance and inflammation are recognized as important links between obesity and cardiovascular disease (CVD). Plasma free fatty acids (FFA), either released from the abnormally enlarged adipose tissue or as part of the excessive nutrient intake, produce insulin resistance and inflammation. Both insulin resistance and inflammation are tightly linked to several independent CVD risk factors such as type 2 diabetes Read More

Intrinsic cardiac aging is an independent risk factor for cardiovascular disease and is associated with structural and functional changes that impede cardiac responses to stress and to cardio-protective mechanisms. Although systemic insulin resistance and the associated risk factors exacerbate cardiac aging, cardiac-specific insulin resistance without confounding systemic alterations, could prevent cardiac aging. Thus, strategies Read More

Diabetes mellitus is associated to an increased risk of cardiovascular diseases. Hyperglycemia is an important factor in cardiovascular damage, working through different mechanisms such as activation of protein kinase C, polyol and hexosamine pathways, advanced glycation end products production. All of these pathways, in association to hyperglycemia-induced mitochondrial dysfunction and endoplasmic reticulum stress, Read More

The increasing prevalence of obesity has significant implications for healthcare, more particularly since it is a major risk factor for type 2 diabetes and cardiovascular diseases. However, not every obese patient is at the same risk of developing future metabolic and cardiovascular complications. Therefore, there is an urgent need for novel biomarkers for early identification of obese patients at high risk. Possible can Read More

Morbid obesity is a chronic multifunctional disease characterized by an accumulation of fat. Epidemiological studies have shown that obesity is associated with cardiovascular and metabolic disorders. Endothelial dysfunction, as defined by an imbalance between relaxing and contractile endothelial factors, plays a central role in the pathogenesis of these cardiometabolic diseases. Diminished bioavailability of nitric oxide ( Read More

Evidence is mounting of the involvement of mitochondrial dysfunction in insulin resistance, diabetes and associated complications. This review aims to provide an overview of the effects of insulin resistance on mitochondrial function in several tissues. We consider the pathogenesis of insulin resistance from a mitochondrial perspective and contemplate potential beneficial effects of strategies aimed at modulating mitochondri Read More

Insulin resistance is associated with the impairment of the response of insulin receptor to insulin, resulting in the reduction of glucose uptake, leading to the alteration of myocardial glucose metabolism, impairment of cardiac electrophysiology, and increased susceptibility to ischemia-induced myocardial injury. Insulin resistance is associated with the impairment of the intracellular insulin signal transduction pathway. A Read More

Adiponectin, a secretory protein specifically expressed by adipose tissue, has been shown to play a critical role in the maintenance of metabolic homeostasis. A deficiency of adiponectin has been linked to a wide variety of metabolic abnormalities, including obesity and associated disorders such as insulin resistance, hyperglycemia, dyslipidemia, hypertension and nonalcoholic fatty liver disease, collectively referred to as the Read More

Polycystic ovary syndrome (PCOS) is a heterogeneous syndrome of reproductive and metabolic derangements. The combination of anovulation and hyperandrogenism signifies the classic form of PCOS which displays the adverse metabolic phenotype of the syndrome. This phenotype includes visceral obesity and insulin resistance as well as a constellation of other traditional cardiovascular risk factors, mainly low grade inflamm Read More

Chronic low-grade subclinical inflammation has been increasingly recognized as an interposer in the endocrine, metabolic and reproductive disturbances that characterize the polycystic ovary syndrome (PCOS). Abdominal adiposity and obesity are often present in PCOS. Mounting evidence indicates that adipose tissue is involved in innate and adaptive immune responses. Continuous release of inflammatory mediat Read More

Stroke is the third leading cause of death and the leading cause of disability in contemporary society. Aneurysmal subarachnoid hemorrhage (aSAH) is a hemorrhagic stroke which accounts for 7% of all stroke cases and 22 to 25% of cerebrovascular deaths. Aneurysmal subarachnoid hemorrhage is a very complex disease and many controversies on its pathophysiology and management have not yet been settled. The aim of this r Read More

Rapid increase in the emergence and spread of microbes resistant to conventionally used antibiotics has become a major threat to global health care. Antimicrobial peptides (AMPs) are considered as a potential source of novel antibiotics because of their numerous advantages such as broad-spectrum activity, lower tendency to induce resistance, immunomodulatory response and unique mode of action. However, AMPs have Read More

The aim of this study was to determine the impact of mean platelet volume (MPV) on the strategy for treatment of atrial fibrillation (AF) with respect to stroke prevention. MPV was analyzed in 265 patients with AF who were undergoing treatment using rhythm or rate control. The primary endpoint was ischemic stroke or a transient ischemic attack (TIA) event. Kaplan-Meier analysis revealed a significantly higher stroke rate Read More

Objective: The mechanisms by which bariatric surgeries, including gastric bypass (GB) and sleeve gastrectomy (SG), achieve remission of type 2 diabetes mellitus (T2DM) and sustained weight reduction are unknown. We hypothesized that the novel anorexic hormone nesfatin-1 and another new hormone obestatin might contribute to the marked improvement in glycemic homeostasis and weight loss in diabetics after GB and Read More
