Prostacyclin and Its Stable Analogue, Iloprost


Book Description

Ten years after the discovery of prostacyclin, our knowledge of its biochemical mode of action, pharmacological properties, pathophysiological significance and therapeutic applications is ever expanding. Prostacyclin is both complex and unique as demonstrated by its unusual feature of being chemically and meta bolically unstable when compared to other prostanoids and known amine or peptide mediators. Although physiologically essential, the chemical instability of prostacyclin poses a serious drawback in laboratory and clinical studies. It is one of the genuine objectives of pharmaceutical research to supply synthetic compounds which overcome the inherent drawbacks - considering investigational and therapeutic use - of endogenous compounds. Whereas metabolic instability in certain cases could be of advantage, chemical instability definitely is not. With Iloprost, a molecule has been designed which - according to all data so far available - pertains high receptor affinity, metabolic instability (clinically this equates with a fine control of Iloprost's effects) while chemical stability has been achieved. By virtue of these characteristics Iloprost can be considered as one step towards specific interaction within the arachidonic acid cascade, namely the prostacyclin receptor. The aim of the symposium was to provide a critical experimental appraisal concerning the biochemical mode of action and pharmacological properties of prostacyclin and Iloprost.

How Tobacco Smoke Causes Disease


Book Description

This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.




Molecular Mechanism of Congenital Heart Disease and Pulmonary Hypertension


Book Description

This open access book focuses on the molecular mechanism of congenital heart disease and pulmonary hypertension, offering new insights into the development of pulmonary circulation and the ductus arteriosus. It describes in detail the molecular mechanisms involved in the development and morphogenesis of the heart, lungs and ductus arteriosus, covering a range of topics such as gene functions, growth factors, transcription factors and cellular interactions, as well as stem cell engineering technologies. The book also presents recent advances in our understanding of the molecular mechanism of lung development, pulmonary hypertension and molecular regulation of the ductus arteriosus. As such, it is an ideal resource for physicians, scientists and investigators interested in the latest findings on the origins of congenital heart disease and potential future therapies involving pulmonary circulation/hypertension and the ductus arteriosus.




From Hypertension to Heart Failure


Book Description

Arterial hypertension, coronary heart disease and heart fail ure are the commonest cardiovascular conditions to present in clinical practice. Over the past few years it has become in creasingly clear that they are closely and causally interrelated and that their relationship can have a significant bearing on prognosis. Epidemiological studies have shown that arterial hypertension is one of the most important risk factors for de veloping heart failure. Only one in four patients with hyper tension is adequately managed, and in 50% of cases, the hypertension has not been recognised or treated. Patients with pre-existing hypertension who go on to suffer an acute myocardial infarction have usually not previously had typi cal angina symptoms, the infarct territory is larger, life threatening arrhythmias are commoner and hence in-hospi tal mortality and long-term prognosis are markedly worse. The presence of raised blood pressure in the post-infarct phase doubles the risk of manifest heart failure. The close relationship between hypertension, coronary heart disease and heart failure makes the choice of therapeu tic strategy particularly important. Agents and classes of agents that have prognostic value in all three conditions should be considered first, as synergy might result in addi tional benefits. In such patients, this sort of therapeutic deci sion-making might have further advantages. The use of these agents may prevent complications which are not yet clinically obvious (such as heart failure).







The Endothelium


Book Description

The endothelium, a monolayer of endothelial cells, constitutes the inner cellular lining of the blood vessels (arteries, veins and capillaries) and the lymphatic system, and therefore is in direct contact with the blood/lymph and the circulating cells. The endothelium is a major player in the control of blood fluidity, platelet aggregation and vascular tone, a major actor in the regulation of immunology, inflammation and angiogenesis, and an important metabolizing and an endocrine organ. Endothelial cells controls vascular tone, and thereby blood flow, by synthesizing and releasing relaxing and contracting factors such as nitric oxide, metabolites of arachidonic acid via the cyclooxygenases, lipoxygenases and cytochrome P450 pathways, various peptides (endothelin, urotensin, CNP, adrenomedullin, etc.), adenosine, purines, reactive oxygen species and so on. Additionally, endothelial ectoenzymes are required steps in the generation of vasoactive hormones such as angiotensin II. An endothelial dysfunction linked to an imbalance in the synthesis and/or the release of these various endothelial factors may explain the initiation of cardiovascular pathologies (from hypertension to atherosclerosis) or their development and perpetuation.

The Impact of Nutrition and Statins on Cardiovascular Diseases


Book Description

The Impact of Nutrition and Statins on Cardiovascular Diseases presents a summary of the background information and published research on the role of food in inhibiting the development of cardiovascular diseases. Written from a food science, food chemistry, and food biochemistry perspective, the book provides insights on the origin of cardiovascular diseases, an analysis of statin therapy, their side effects, and the role of dietary intervention as an alternative solution to preventing cardiovascular diseases. It focuses on the efficacy of nutrition and statins to address inflammation and inhibit the onset of disease, while also providing nutrition information and suggested dietary interventions.
