Thrombosis is the condition where an imbalance in the homeostatic mechanism results in unwanted intravascular thrombus formation. Imbalances in this highly regulated process of coagulation and anticoagulation can lead to a variety of pathophysiological conditions leading to stroke, pulmonary heart attack and other serious conditions. In the western world, thromboembolic diseases are the leading cause of morbidity Read More

Awareness of the importance of carbohydrates in living systems and medicine is growing due to the increasing understanding of their biological and pharmacological relevance. Carbohydrates are ubiquitous and perform a wide array of biological roles. Carbohydrate-based or -modified therapeutics are used extensively in cardiovascular and hematological treatments ranging from inflammatory diseases and anti-thromb Read More

The molecular pathogenesis of the myeloproliferative disorders (MPD) is poorly understood, except for chronic myeloid leukemia (CML). Recently, several groups have discovered a novel recurrent unique acquired clonal mutation in a tyrosine-kinase JAK2 in patients with Philadelphia-negative MPD and other myeloid disorders. It consists in a guanineto- thymine change encoding a valine to phenylalanine at codon 617 (JAK2 V61 Read More

Nitric oxide (NO) is a molecule that dynamically modulates the physiological functions of the cardiovascular system, which include relaxation of vascular smooth muscle, inhibition of platelet aggregation, and regulation of immune responses. Because a reduced NO level has been implicated in the onset and progression of various disease states, NO is expected to provide therapeutic benefits in the treatment of cardiovascular Read More

Metabolic syndrome is defined as the combination of abdominal obesity, insulin resistance, atherogenic dyslipidemia, and prothrombotic and proinflammatory states. Due to the epidemic proportion of overweight and obesity worldwide and the development of useful clinical tools to identify these patients more easily, metabolic syndrome is increasingly recognized in adults and represents a clear risk factor for the developme Read More

Statins are competitive inhibitors of HMG-CoA reductase, the rate-limiting enzyme of cholesterol biosynthesis. Statins are widely and successfully used for lowering plasma cholesterol levels causing up to 45% reduction of plasma cholesterol and considerable reduction in risk of cardiovascular diseases. The main atheroprotective action of statins is reduction of plasma low density lipoprotein levels due to improved clearance of t Read More

Protozoan tropical diseases cause great suffering throughout developing countries, with high rates of morbidity and mortality. American Trypanosomiasis affects 16-18 million people in Latin America, representing a dramatic disease among symptomatic patients. Old, toxic and ineffective chemotherapeutic agents continue to be used for the treatment of Chagas' disease. Since the early days of medicine, chemi Read More

Accelerated atherosclerosis and microvascular complications are perhaps the leading cause of coronary heart disease, blindness and renal failure, which could account for disabilities and high mortality rates in patients with diabetes. Several mechanisms including endothelial cell damage, platelet activation and aggregation, hypercoagulability, and impaired fibrinolysis are involved in the pathogenesis of thrombogenic diath Read More

Dopamine receptors have been identified in a number of organs and tissues, which include the central and peripheral nervous systems, various vascular beds, the heart, the gastrointestinal tract, and the kidney. Dopamine receptors are classified into D1- and D2-like subtypes based on their structure and pharmacology; during conditions of moderate sodium balance, more than 50% of renal sodium excretion is regulated by Read More
