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.

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.

The environment in which human beings live is complex and we may encounter many different potentially toxic chemical substances during the course of our lives. These xenobiotic agents may invade the living system in the form of environmental pollutants, in the diet, as pharmaceutically administered compounds or even as chemical weapons and it is becoming widely recognised that free radicals are often involved in this toxicity. The book covers all aspects of toxic agents in the environment from their detection to their effects. Final year undergraduates and postgraduates studying toxicology, biochemistry, cell biology or environmental science will find this book valuable reading, whilst researchers in academia, the pharmaceutical industry, and public health laboratories will appreciate it as a comprehensive reference.

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.

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.

The role of oxidative stress in human disease has become an area of intense interest. Free radicals, a normal product of metabolism, exist in all aerobic cells in balance with biochemical antioxidants. Environmental stress increases the levels of free radicals drastically, thereby disturbing the equilibrium between free radical production and the antioxidant capability causing oxidative stress. Over the years, ROS has been implicated in the pathologies of various diseases like cancer, neurological disorder, cardiovascular diseases rheumatoid arthritis, diabetes etc. This book provides an in depth critical state-of-art reviews from established investigators on free radicals, ROS associated pathogenesis of human diseases, biomarkers of oxidative damage, antioxidants, phytonutrients and other related health concerns of modern society. The present book is aimed at graduate students, researchers in academia, industry and clinicians with the interest in redox biology. Special attention has been devoted to the topic of ROS signalling, oxidative stress induced human pathologies & antioxidative therapies. The book consists of four parts in specified topics based on the current literatures for the better understanding of the readers with respect to their subject-wise interests. The first section of the book provides an overview about the ROS production and their measuring tools and techniques followed by the mechanisms involved in the oxidative stress in the second section. The third section describes the involvement of oxidative stress in different human diseases and the last section focuses on the different strategies to ameliorate oxidative stress induced stress.

Mitochondria are tiny structures located inside our cells that carry out the essential task of producing energy for the cell. They are found in all complex living things, and in that sense, they are fundamental for driving complex life on the planet. But there is much more to them than that. Mitochondria have their own DNA, with their own small collection of genes, separate from those in the cell nucleus. It is thought that they were once bacteria living independent lives. Their enslavement within the larger cell was a turning point in the evolution of life, enabling the development of complex organisms and, closely related, the origin of two sexes. Unlike the DNA in the nucleus, mitochondrial DNA is passed down exclusively (or almost exclusively) via the female line. That's why it has been used by some researchers to trace human ancestry daughter-to-mother, to 'Mitochondrial Eve'. Mitochondria give us important information about our evolutionary history. And that's not all. Mitochondrial genes mutate much faster than those in the nucleus because of the free radicals produced in their energy-generating role. This high mutation rate lies behind our ageing and certain congenital diseases. The latest research suggests that mitochondria play a key role in degenerative diseases such as cancer, through their involvement in precipitating cell suicide. Mitochondria, then, are pivotal in power, sex, and suicide. In this fascinating and thought-provoking book, Nick Lane brings together the latest research findings in this exciting field to show how our growing understanding of mitochondria is shedding light on how complex life evolved, why sex arose (why don't we just bud?), and why we age and die. This understanding is of fundamental importance, both in understanding how we and all other complex life came to be, but also in order to be able to control our own illnesses, and delay our degeneration and death. 'An extraordinary account of groundbreaking modern science... The book abounds with interesting and important ideas.' Mark Ridley, Department of Zoology, University of Oxford
