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.

Book Description
Merely three years after the discovery of endothelin, a large amount of information has been generated about the molecular biology, biosynthesis, biological actions and potential physiological and pathological importance of this unique peptide and its isoforms. This first book on endothelins summarizes the early events which lead to the discovery of endothelin, the progress made in understanding the peptide's physiological role, and the current state-of-the-art in contemporary endothelin research. The book also discusses the potential significance of endothelins in health and disease, covers the potential role of the peptides in the integrated control of the cardiovascular system, and outlines future research directions. This comprehensive monograph is an indispensable reference for basic scientists and clinicians.

Book Description
Written by the foremost authority in the field, this volume is a comprehensive review of the multifaceted phenomenon of hepatotoxicity. Dr. Zimmerman examines the interface between chemicals and the liver; the latest research in experimental hepatotoxicology; the hepatotoxic risks of household, industrial, and environmental chemicals; and the adverse effects of drugs on the liver. This thoroughly revised, updated Second Edition features a greatly expanded section on the wide variety of drugs that can cause liver injury. For quick reference, an appendix lists these medications and their associated hepatic injuries. Also included are in-depth discussions of drug metabolism and factors affecting susceptibility to liver injury.

Book Description
Recent publications have addressed specific aspects of the endothelins, such as their roles in disease or the importance of endothelin receptors. However, in this book the entire field of endothelins is covered. This includes the pathways of endothelin production and their regulation, the local and systemic actions of endothelins, receptors for the endothelins and the signalling pathways employed, and the involvement of endothelins in a range of diseases. Attention is also paid to the development through chemistry, pharmacology and toxicology of endothelin antagonists and endothelin-converting enzyme inhibitors, with mention of all the important members of these drug classes. This leads to well-rounded discussions of the potential therapeutic benefit of endothelin inhibitors.

Book Description
Since the discovery of endothelin, major advances have been made in understanding the molecular structure and function of the endothelin receptors. At least two subtypes of receptors, designated ETA and ETB, have been identified through biochemical and pharmacological techniques. These subtypes are cloned and expressed and additional subtypes appear to exist. The biochemical events involved in the signal transduction processes that ultimately activate the cellular machinery involved in the end-organ responses are presented, as are the mechanisms by which the receptors recognize specific and different G-proteins. Functions mediated by the receptors at the cellular, tissue and, organ level are reviewed in detail, as well as the roles that they may play a part in the physiologic and pathophysiologic processes in animals and in humans. This book is unique in its breadth of scope. The most recent and important advances, from the intracellular level of the nucleus to the functional effect that endothelin receptors mediate in intact organs, are compiled and reviewed.

Book Description
This book focuses on the wide variety of intracellular events that occur as a result of endothelin receptor activation. This includes a discussion of the various pathways by which endothelin activates Ca2+ signals from several intra- and extracellular sources and the effects of endothelin on ion channels and membrane function. In addition, the mechanisms by which endothelin influences the ion transport within the renal epithelium are covered, as well as the signal transduction pathways activated by endothelin in both cardiac tissue and vascular smooth muscle.

Book Description
A panel of multidisciplinary experts describes in detail readily reproducible methods to investigate all aspects of the endothelin system from its synthesis and metabolism, to its function in health and disease. Theses methods use state-of-the-art molecular techniques to quantify the expression of mRNA for both endothelin receptors and the endothelin converting enzymes. They show how peptides, precursors, receptors, and synthetic enzymes can be localized and quantified in plasma, culture supernatants, tissue homogenate, and tissue sections using antibodies. Several in vivo protocols illustrate the role of the endothelin peptides in healthy human individuals and describe animal models that can be used to predict the therapeutic potential of cardiovascular drugs that manipulate endothelin synthesis or function.

Book Description
"What we call the beginning is often the end, and to make an end is to make a beginning. The end is where we start from." T. S. ELIOT, "Geroniton" The discovery of endothelin-l was both an end and a beginning. It is an end because this discovery has started a plethora of investigations as to endothe1in's sites of production, mode of action, it's normal and abnormal physiological role and its involvement in a variety of pathological conditions ranging from renal failure to myocardial infarction, cardiac hypertrophy, hyperten sion, cyclosporine induced toxicity, mental depression, renal failure, stress related illness, and even stroke and sudden death. It is a beginning because no one can foresee where the investigations will ultimately lead, or how they will end. The discovery of the endothelins was a very recent event and soon specialist books will start to appear dealing in detail with different aspects of their chemistry, physiological role and pathological importance. The present book is intended to act as a guide and primer for those who are becoming intrigued by the many endothelin related articles which are now appearing in the journals but who as yet have not had the time or opportunity to be caught up in the web of enthusiasm and excitement which is motivating those more directly involved in the field of research.
