Book Description
Free Radicals in Biology, Volume VI covers the significant biological implications of arachidonic acid chemistry in free radical biology. This 11-chapter volume explores the biochemistry of the prostaglandins, leukotrienes, and other products from arachidonic acid. The introductory chapters describe the chemistry of the eicosanoids; the structures of prostaglandin and leukotriene compounds; the role of lipid hydroperoxides in controlling prostaglandin biosynthesis; and the oxidation of xenobiotics during prostaglandin H biosynthesis. The discussion then shifts to the effects of the so-called fatty acid paradoxes on cell proliferation, tumorigenesis, and metastasis, followed by chapters on arachidonic acid cascade process; the causes of lung injury conditions, such as hyperoxia; and the origin of low-level chemiluminescence in cells. This volume further deals with the oxy-radical involvement in parasitic diseases and the mechanisms for activation of aromatic amine carcinogens. The concluding chapters examine the controversial one- and two-electron mechanisms for activation of polynuclear hydrocarbon carcinogens and a hypothesis to rationalize the effects of radicals on the life span of mammals. These chapters propose that aging results from toxic by-products of metabolism, and longevity is determined by the ability of an organism to deal with these products. This book will be of great benefit to biochemists, biologists, and physicists.

Book Description
Free Radicals in Biology and Medicine has become a classic text in the field of free radical and antioxidant research. Now in its fifth edition, the book has been comprehensively rewritten and updated whilst maintaining the clarity of its predecessors. Two new chapters discuss 'in vivo' and 'dietary' antioxidants, the first emphasising the role of peroxiredoxins and integrated defence mechanisms which allow useful roles for ROS, and the second containing new information on the role of fruits, vegetables, and vitamins in health and disease. This new edition also contains expanded coverage of the mechanisms of oxidative damage to lipids, DNA, and proteins (and the repair of such damage), and the roles played by reactive species in signal transduction, cell survival, death, human reproduction, defence mechanisms of animals and plants against pathogens, and other important biological events. The methodologies available to measure reactive species and oxidative damage (and their potential pitfalls) have been fully updated, as have the topics of phagocyte ROS production, NADPH oxidase enzymes, and toxicology. There is a detailed and critical evaluation of the role of free radicals and other reactive species in human diseases, especially cancer, cardiovascular, chronic inflammatory and neurodegenerative diseases. New aspects of ageing are discussed in the context of the free radical theory of ageing. This book is recommended as a comprehensive introduction to the field for students, educators, clinicians, and researchers. It will also be an invaluable companion to all those interested in the role of free radicals in the life and biomedical sciences.

Book Description
Free Radicals in Biology, Volume 1, provides an introduction to some of the basic concepts of free radical biology. The book emerged from the President's Symposium of the American Society for Experimental Pathology held in Atlantic City in April 1970. The book's opening chapter introduces a mechanistic view of free radical reactions using examples from biological systems. This is followed by a discussion of autoxidative damage to lipids in membranes. Some of the special chemistry of lipid oxidation are presented, and a number of novel ideas are suggested. The third chapter deals with the uses of electron-spin resonance in biology. Spin labeling is also discussed, which is one of the most useful methods of probing the chemical and physical environment of molecules in cells. The remaining chapters cover free radicals which occur in photosynthesis and the importance of the enzyme, superoxide dismutase. The study of the occurrence and reactions of this enzyme provides an important and extensive body of data clearly pointing to the significance of free radicals in cellular chemistry.

Book Description
Although free radicals perform some useful immune functions, they can also damage healthy cells through a process called oxidation. Antioxidants reduce the effect of free radicals by binding together with these harmful molecules, decreasing their destructive power. This book highlights various issues of free radical biology from the perspective of antioxidant defense mechanisms. It also provides useful information on gene modulation, radiation-generated reactive oxygen species-induced apoptosis in cancer, and environmental aspects associated with free radicals’ exposure on living systems.

Book Description
Our understanding of the quantitative aspects of free radical chemistry and the involvement of radicals in such areas as biology, medicine, the environment, etc., has developed spectacularly over recent years, yet the various topics are commonly discussed separately, in specific meetings and specialised publications. Free Radicals in Biology and Environment draws together two important areas of free radical chemistry, using as a bridge the fundamental physical chemistry of free radicals (spectroscopic detection of free radicals, evaluation of absolute rate constants, elucidation of mechanisms of free radical reactions and catalysis, photochemical and radiation processes, etc.). The most relevant topics covered are the EPR detection of radicals in biochemical systems and in pollutant formation and degradation, oxidation processes in biology and in the troposphere, radiation and induced damage, and atmospheric pollutants arising from incomplete combustion. Also covered are the chemistry and biochemistry of nitric oxide and peroxynitrite, the chemistry and biochemistry of DNA radicals, the role of radicals in myeloperoxidase, lignineperoxidase, radicals and cardiovascular injury, radiation and the fragmentation of cells and tissues.

Book Description
Oxidative Stress and Antioxidant Protection: The Science of Free Radical Biology and Disease Oxidative Stress and Antioxidant Protection begins with a historical perspective of pioneers in oxidative stress with an introductory section that explains the basic principles related to oxidative stress in biochemistry and molecular biology, demonstrating both pathways and biomarkers. This section also covers diagnostic imaging and differential diagnostics. The following section covers psychological, physiologic, pharmacologic and pathologic correlates. This section addresses inheritance, gender, nutrition, obesity, family history, behavior modification, natural herbal-botanical products, and supplementation in the treatment of disease. Clinical trials are also summarized for major medical disorders and efficacy of treatment, with particular focus on inflammation, immune response, recycling, disease progression, outcomes and interventions. Each of the chapters describes what biomarker(s) and physiological functions may be relevant to a concept of specific disease and potential alternative therapy. The chapters cover medical terminology, developmental change, effects of aging, senescence, lifespan, and wound healing, and also illustrates cross-over exposure to other fields. The final chapter covers how and when to interpret appropriate data used in entry level biostatistics and epidemiology. Authored and edited by leaders in the field, Oxidative Stress and Antioxidant Protection will be an invaluable resource for students and researchers studying cell biology, molecular biology, and biochemistry, as well professionals in various health science fields.

Book Description
Free Radicals in Biology, Volume IV reviews diverse topics in free radical biology and covers topics ranging from radiation biology to lipid peroxidation, radical-mediated liver pathology, and chemical carcinogenesis. Radical mechanisms in prostaglandin biochemistry are also discussed, along with the use of electron spin resonance and spin trap methods to probe mechanisms of radical reactions in biological systems. Comprised of 10 chapters, this volume begins with an overview of the mechanisms of lipid peroxidation, focusing on the chemistry of fluorescent products from in vivo lipid peroxidation; the production of pentane in the expired breath of animals exposed to oxidative threats; and the chemistry of the enzyme glutathione peroxidase. The next chapter is devoted to the kinetic aspects of lipid peroxidation and the multiple ways in which autoxidants can react. The reader is then introduced to the mechanisms of hepatoxicity by synthetic chemicals present in the environment, together with direct mechanisms of radiation damage to nucleic acids. Subsequent chapters deal with spin trapping in biological systems; the role of free radicals in arylamine carcinogenesis and their influence on the structure and reactivity of melanins; and the involvement of vitamin ? and lipid antioxidants in free-radical-initiated reactions. This book will be of value to chemists, biologists, and physicians.
