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.

Oxidants, like other aspects of life, involves tradeoffs. Oxidants, whether intentionally produced or by-products of normal metabolism can either mediate a variety of critical biological processes but when present inappropriately cause extensive damage to biological molecules (DNA, proteins, and lipids). These effects can lead to either damage that is a major contributor to aging and degenerative diseases (or to other diseases such as cancer, cardiovascular disease, immune-system decline, brain dysfunction, and cataracts) or normal physiological function- tissue repair, defense against pathogens and cellular proliferation. On the other hand the body is equipped with a complex antioxidant/oxidant handling system which includes both enzymatic and nonenzymatic (i.e. small molecules such as flavonoids, ascorbate, tocopherol, and carotenoids) produced endogenously or derived from the diet. This book focuses on how the same molecules can have favorable or noxious effects depending on location, level and timing. Each chapter focuses on one particular molecule or oxidant/antioxidant system and provides a state of the art review of the current understanding regarding both positive and negative actions of the system under review.
Literally thousands of papers have been published on nitric oxide over the past ten years. But there is no single monograph available that has previously attempted to summarize the important features of the roles of nitric oxide in inflammation. The voluminous literature regarding the incredible range of chemical and biological effects of nitric oxide and reactive nitrogen oxide species, RNOS, may present a tangle of confusing information to the researcher. This volume brings together experts from nitric oxide and inflammation research and presents a concise up-to-date overview as well as future aspects of this rapidly growing field.
A number of remarkable recent breakthroughs have made the study of nitric oxide one of the most exciting fields in physiology and pathophysiology. This authoritative edited volume reviews the progress to date and opens perspectives to novel diagnostic and therapeutic strategies. The contributors are leading authorites, in most cases the investigators who have pioneered the ideas explored in the book.
Nitric oxide (NO) is a gas naturally found in the body that conveys information between cells. In the last decade researchers have found that NO is a signaling molecule of key importance for the cardiovascular system, regulating blood pressure and blood flow to different organs. In addition, discoveries surrounding nitric oxide's role as a principal neurotransmitter moderating erectile function, a pathophysiological negotiator and messenger in inflammation, and a weapon against infections have increased research attention across the fields of biochemistry, chemistry, molecular biology, gene therapy, cell biology, immunology, pharmacology, neuroscience, and physiology. - Edited by Nobel Laureate Louis J.

Nitric oxide (NO) is a key regulator of various cellular signaling pathways throughout the body and plays an important role in renal function under normal physiological and pathophysiological conditions. NO plays a major role in the regulation of renal hemodynamics, tubuloglomerular feedback, sodium transport in the nephron, pressure natriuresis, and renal fibrosis and injury; moreover, a deficiency in NO is characteristic of chronic kidney disease in both human patients and in experimental animal models. The goal of this book is to highlight the actions of NO within the kidney and its effects on the regulation of renal blood flow and tubular transport.
Nitric oxide (NO) has been discovered to play a fundamental role in a number of biological phenomena. This book describes various aspects of nitric oxide biology, physiology and pharmacology. It is divided into three sections. The first part deals with the basic chemistry and enzymology of NO, thus laying a molecular basis for what follows. The middle part surveys the physiological roles of NO under normal conditions. The concluding part explores the relevance of NO to disease, both as a pathogenic factor and a therapeutic target. The book thus provides detailed information on NO biology to the reader unfamiliar with the field and represents a reference work for scientists working in an NO-related field of biomedical research. Each chapter, written by experts in their fields, gives a broad introduction followed by a comprehensive review of the current knowledge and a detailed reference list.
