Lipoxygenases and Their Products


Book Description

Lipoxygenases and Their Products provides a cogent summary of the advances in understanding lipoxygenases and their products, emphasizing their pharmacology and pathophysiology; regulation and structure; physiological role; and receptors and receptor antagonists. This text also reviews the literature where specific receptor antagonists (as opposed to enzymatic inhibitors) have been used to characterize the pharmacologic action and the pathophysiologic roles of some of lipoxygenase products of arachidonic acid metabolism. This book is organized into 11 chapters and begins with an overview of the biochemical, pharmacological, and pathophysiological aspects of 5-lipoxygenase products of arachidonic acid metabolism in the respiratory, cardiovascular, renal, gastrointestinal, and central nervous systems. The discussion then shifts to human 5-lipoxygenase, emphasizing this enzyme purification, stimulatory factors, and membrane translocation. The reader is methodically introduced to 5-lipoxygenase activity in rats and pigs; the potential and therapeutic value of 5-lipoxygenase inhibitors; the distribution of 15-lipoxygenase in cells or tissues; and products formed through the 15-lipoxygenase pathway. This book also considers lipoxins and third-generation peptidoleukotriene receptor antagonists, and then concludes with a summary of the physiological and pathophysiological effects of leukotrienes and lipoxins in a variety of organs. This book is of interest to scientists interested in arachidonic acid and its metabolites, to scientists engaged in drug discovery-and-development activities in academia and the pharmaceutical industry, and to clinicians interested in diseases associated with leukotrienes and related products.

Antioxidant and Redox Regulation of Genes


Book Description

This volume addresses oxidant-reduction or redox and antioxidant sensitive molecular mechanisms and how they are implicated in different disease processes. Possible strategies to pharmacologically and/or nutritionally manipulate such redox-sensitive molecular responses are emphasized. - Reactive species as intracellular messengers - Redox regulation of cellular responses - Clinical implications of redox signaling and antioxidant therapy




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. Table of Contents: Introduction / Multiple Functions of the Endothelial Cells / Calcium Signaling in Vascular Cells and Cell-to-Cell Communications / Endothelium-Dependent Regulation of Vascular Tone / Conclusion / References




The Molecular Targets and Therapeutic Uses of Curcumin in Health and Disease


Book Description

The medicinal uses of Curcumin (also called turmeric) have been known and described for more than 5000 years. A large body of recent research suggests that curcumin is potentially useful in the treatment of inflammatory diseases, through modulation of numerous molecular targets. This is the first monograph to focus on the potential use of curcumin in the treatment of cancer, diabetes, cardiovascular diseases, arthritis, Alzheimer’s, psoriasis and more.




Cosmeceuticals


Book Description

Cosmeceuticals are ingredients or products that provide cosmetic and therapeutic benefits and which can be obtained without a prescription. They are one of the fastest growing segments in the personal care product market. Even in the worst economic climate, sales of cosmetics remain robust. Beauty enhancers are our best means of feel-good escapism, and we are not about to give them up. The ingredients, sales locations, and the regulation of sales are dynamic aspects of the industry. Here we give you a heads-up on where the market is going so you can make strategic decisions for your practice. This book will give you an understanding of facial cosmeceuticals examining the needs of the face, moisturizer formulation, noninvasive testing, and clinical evaluation to establish efficacy. It sheds light on topics such as the delivery mechanisms of active ingredients, vitamin A and C and other antioxidants, growth factors and stem cells, peptides, or amino acids. Topics also include the use of cosmeceuticals for the treatment of acne, rosacea, and hair loss and for hair care as well as the treatment of scars and cosmeceuticals for sun protection and protection from pollution. It also covers aspects of nutraceuticals and diets for healthy skin.




Bioactive Lipids


Book Description

In Bioactive lipids, Anna Nicolaou and George Kokotos have brought together an international team of authors to discuss the nomenclature, structures, biochemistry, pharmacology and recent developments in the main classes of bioactive lipids. These lipids are essential components of the cell membrane and play many dynamic roles in mediating and controlling a wide array of cellular activities including membrane structure and organization, metabolic and gene regulation, protein structure and function, energy production, and signalling pathways. The lipid interests of scientists in the pharmaceutical and food industries are converging as the broader significance of bioactive lipids is increasingly recognized. Lipids and lipid-metabolizing enzymes are targeted for the development of new drugs. Meanwhile, functional foods, nutraceuticals and supplements already have lipids as major active ingredients. The food industry will progress from simply using lipids as ingredients, to the formulation of products that influence the synthesis, metabolism and effects of bioactive lipids in the body. These advances in applied lipid biochemistry will build on the fundamental research of lipid scientists in universities worldwide, such as those scientists contributing to Bioactive lipids.
