Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Free Radicals in Biology and Medicine written by Barry Halliwell and published by OUP Oxford. This book was released on 2015-08-21 with total page 961 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2013-04-17 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2013-03-09 with total page 1064 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is based on the papers presented at the "Fourth International Congress on Oxygen Radicals (4-ICOR)," held June 27 - July 3, 1987, at the University of California, La Jolla. The chapters deal with the phenomena associated with highly reactive oxygen species (hydroxy, peroxy, alkoxy, aroxy, and superoxide radicals, as well as singlet oxygen) and their peroxidation products (hydrogen peroxide, hydroperoxides, peroxides, and epoxides) as they relate to the fields of chemistry, food technology, nutrition, biology, pharmacology, and medicine. The kinetics, energetics, and mechanistic aspects of the reactions of these species and the interrelationship of oxygen radicals (or any other free radicals) and peroxidized products have been emphasized. Special attention is focused on the mechanisms of the generation of free radicals and peroxy products in biosystems and on the adverse effects of these radicals and products in humans. The topics span the continuum from the simple chemistry of model systems to the complex considerations of clinical medicine. The book also explores the mechanisms of agents that protect against free radicals and peroxy products in vitro and in vivo. These agents include antioxidants used in materials, food antioxidants, physiological antioxidants, and antioxienzymes (SOD, glutathione peroxidase, and catalases). The use of these inhibitors to prevent damage to organs being prepared for transplantation, thereby maintaining the quality of transplanted organs and/or extending their "shelf-life," also is examined.

Download or read book Free Radicals in Biology V6 written by William Pryor and published by Elsevier. This book was released on 2012-12-02 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Free Radicals in Biology V5 written by William Pryor and published by Elsevier. This book was released on 2012-12-02 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Free Radicals in Biology, Volume V covers the mechanisms for the generation of free radicals. This volume contains eight chapters that discuss the biology and chemistry of oxy-radicals in mitochondria and the radical-mediated metabolism of xenobiotics. The opening chapter describes the mechanisms of free radical production in enzymatically promoted lipid peroxidation, generally in microsomes or microsomal lipids. The subsequent chapters explore the biochemistry and biology of plant and animal lipoxygenases; the production of superoxide and hydrogen peroxide in mitochondria; and the biological role of these species in mitochondria and related systems. The discussions then shift to the effects of superoxide production in white blood cells, with an emphasis on an evaluation of the oxygen-dependent reactions of the important phagocytic cells, the monocytes, and the polymorphonuclear leukocytes. This volume further covers the formation and the role of oxy-radicals in the red blood cell, which is a very useful system for studying the protection of biological tissue against radical-mediated damage. A chapter presents a comprehensive review of the production of free radicals during the metabolism of xenobiotics. The last chapters provide an overview of the enzymology, biological functions, and free radical chemistry of glutathione peroxidase. These chapters also examine a number of gerontological principles and the effect of antioxidants in aging. Chemists, biologists, and physicists will find this book of great value.

Download or read book Analysis of Free Radicals in Biological Systems written by A. Favier and published by Birkhäuser. This book was released on 2012-12-06 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Oxidative stress" is used as the generic term describing the involve ment of reactive oxygen species in various human diseases. The scope of such a topic is becoming increasingly wide. The recent interest in radicals such as nitric oxide and the discovery of new mechanisms such as the effect of free radicals on redox sensitive proteins and genes are enlarging our understanding of the physiological role of free radicals. Oxidative stress is involved in numerous pathological. processes such as ageing, respiratory or cardiovascular diseases, cancer, neurological pathologies such as dementia or Parkinson's disease. It still remains difficult, however, to demonstrate by chemical measurement the in vivo production of free radicals and even more to realise their speciation. Therefore, the development of new tools and indicators is engrossing many researchers working in this field. Reliable indicators are abso lutely necessary not only to monitor the evolution of oxidative stress in patients but also to evaluate the efficiency of new antioxidant treat ments. The French Free radical club of Grenoble, the CERLIB has been involved for many years in the organisation of international training programs on methodology, in order to provide both theoretical and practical help to researchers from various countries. Such training sessions have been highly successful and participants value the oppor tunity to learn reliable techniques. This positive echo explains why the researchers of CERLIB decided, with the help of Prof. Dr. B. Kalyanaraman, to publish selected techniques on free radical re search.
