Description : "This latest edition has been comprehensively rewritten and updated (over 80% of the text is new), whilst maintaining the clarity of its predecessor. There is expanded coverage of isoprostanes and related compounds, mechanisms of oxidative damage to DNA and proteins (and the repair of such damage), the free radical theory of ageing and the roles played by reactive species in signal transduction, cell death, human reproduction, and other important biological events. Greater emphasis has also been placed on the methods available to measure reactive species and oxidative damage (and their potential pitfalls), as well as the importance of antioxidants in the human diet." "This book is recommended as a comprehensive introduction to the field for students, clinicians and researchers, and an invaluable companion to all those interested in the role of free radicals in the life and medical sciences."--BOOK JACKET.

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.

Description : "Oxidative stress and inflammatory cell death / tissue damage have been implicated in a wide array of human diseases, including cancer, neurodegenerative diseases, diabetes, inflammatory joint diseases,; cardiovascular dysfunctions as well as ageing. Oxidative stress mediates the activation of transcription factors such as NF?B that, in turn, induce the transcription of certain genes promoting cytokine production. Release of these cytokines results in the enhancement of inflammatory responses and activation of endothelial cells in distant organs. The inflammatory cascade is then triggered by the induction of adhesion molecules and the generation of cytokines and other inflammatory mediators. Given that reactive oxygen and nitrogen species (ROS and RNS respectively) generated by infiltrated neutrophils into distant organs act directly as noxious agents reacting with molecular components, thereby enhancing inflammatory processes and therefore influencing cell viability, ROS and RNS have become potential therapeutic targets for prophylactic biofactors. Whilst their production by phagocytic cells is, of course, essential for the eradication of invading pathogens, and the capacity of selected chemotherapeutic agents to generate such species in specific `target' cells is well known in cancer research, the novel therapeutic actions and potential mechanisms of action of ozone as a microbicidal agent in clinical dentistry are now being advocated. The focus of this publication prominently encompasses the pivotal roles of ROS and RNS in the pathogenesis of many clinical conditions (together with their involvement in the ageing process of lower (yeast) cells, and higher organisms including plants), and discusses the potential applications of dietary-derived antioxidants to interfere with the biomolecular mechanisms of these processes and hence offer realistic therapeutic or prophylactic potentials."

Description : 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.

Description : Excited states and free radicals are involved in the normal physiology of living systems, in pathological processes (including lipid peroxidation, inflammation, Parkinson's disease, cancer, and aging), in the mechanisms of drug action, and in the photochemotherapies such as the PUVA therapy for skin diseases and PDT for cancer. This text introduces the reader to this rapidly expanding field, one that lies at the borderlines of physics, chemistry, biology, pharmacology, and medicine. The authors explore in particular how time-resolved spectroscopic methods have found solutions at the molecular level to biological and medical problems. Topics include the nature of excited states and free radicals and the techniques for their study, activated oxygen species, DNA, proteins, carotenoids and photosynthetic reaction centers, photodermatology and melanogenesis, and aspects of cancer related to radio-, chemo-, and photodynamic therapy. Researchers and graduate students in photochemistry, photobiology, photomedicine, radiation chemistry and biology, and cancer therapies will find this book to be of very significant interest.

Description : There is a growing body of experimental and clinical data to suggest that the organs of the digestive system may be subjected to considerable oxidative stress associated with acute and chronic inflammation. Although inflammation and ischemia play a key role in producing oxygen-derived free radicals in the digestive tract, the contribution of other factors, such as transition metal imbalances, lipid and glucose metabolic disturbance, and the interaction with gaseous molecules including nitric oxide and carbon monoxide, has also been suggested. Recent studies have demonstrated that several biomarkers indicating oxidative stress-mediated damage may help in monitoring the degree of disease and planning the design of new therapeutic strategies. In addition, recent advances in 'omics' research (genomics, proteomics, metabolomics, etc.) may bring a breakthrough in the field of gastroenterology and hepatology: Several molecular targets for oxidative stress have been presented by the 'omics'. This book includes up-to-date reviews on the relevant issues in free radical biology in a combination with expert basic research reviews and clinical aspects in gastroenterology and hepatology. Providing information about new molecular targets for the treatment or prevention of digestive diseases, this book should be read by clinical and basic researchers in gastroenterology and hepatology.
