Book excerpt: An International Syaposiua on Free Radicals in Diagnostic Medicine was co-sponsored by the state University of New York at Buffalo, Roswell Park Cancer Institute, and the Upstate NY Section of the American Association of Clinical Chemistry. The theme was "A Systems Approach To Laboratory Technology, Clinical Correlations And Antioxidant Therapy." The symposium was held on October 7-8, 1993 at the Hyatt Hotel and on October 9 at Roswell Park Cancer Institute, Buffalo, New York. This proceedings volume contains chapters from platform presentations, poster sessions and from invited special lectures in the areas of basic science, clinical applications and efficacy of treatment. A Special Lecture on the relevance of free radical analysis to clinical medicine was presented by Professor Kunio Yagi of Japan. The Yagi procedure to measure thiobarbituric acid (TBA) reaction reflects the amount of reactive substances, lipid peroxides and aldehydes, in the sample. For example, normal subjects will have less than 4 nmol/ml of serum lipid peroxides, while a person with diabetes generally has equal or greater than 5.0 and a diabetic person with vascular complications often exceeds 7.5 nmol/ml. Serum TBA is a clinically important measure that relates to aging, gender and estrogen as an antioxidant, in the prognosis for vascular disorders, and in pathological conditions relative to the amount of lipid peroxidation. The BASIC SCIENCES portion of the program examined: "Mechanisms of Action, Pathophysiology and Laboratory Tests" in six presentations.

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

Book excerpt: Free radicals are defined as any chemical species capable of independent existence, which contains at least one unpaired electron. Molecular divalent oxygen itself is by definition a free radical. The term reactive oxygen species (ROS) and reactive nitrogen species (RNS) are freely used in the literature. They refer to free radicals such as superoxide anion (O2"-), hydroxyl radical (HO") and nitric oxide (NO), and even to the non-radicals such as hydrogen peroxide (H2O2) and peroxynitrite (ONOO-). It has been shown that ROS and RNS are involved in a variety of physiological and pathological processes such as mutation, carcinogenesis, aging, atherosclerosis, inflammation, ischemia-reperfusion, and neurodegenerative diseases. Moreover, the importance of mitochondrial metabolism of these species in pathophysiological events, has been addressed. We believe that the readers of this book will find the real frontline areas of free radical research in pathophysiology. There is a bright future for investigations in this area, and we hope that this book will be helpful to every person interested in free radicals. This book has 24 chapters that are divided into 5 major sections that lead from basic concepts in free radical biology to clinically applied investigations. The book begins with an updated overview of basic principles on oxidative and nitrosative stress (Section 1). It takes us through the concept of oxidative stress and lipid peroxidation, 3-nitrotyrosine and nitrated lipids as markers of nitrosative stress, the effect of ferritin on ascorbyl radical content, and ends with the description of the antioxidant network and the relevance of flavanols and procyanidins for disease. Section 2 addresses the importance of mitochondria in pathophysiology. It is reviewed not only the role of mitochondria in cell death and the importance of the uncoupling proteins, but the nitric oxide metabolism and mitochondrial nitric oxide synthase from heart, as well. This section ends reviewing the relationship between mitochondrial oxidative stress and the permeability transition. The role of free radicals in inflammatory conditions is described in section 3. By starting with the discussion of the oxygen/nitric oxide metabolism in sepsis and the oxidative stress generated by the exposition to particulate matter, it ends with actualizations on the role of iron and the therapeutic role of melatonin in inflammation and sepsis. Section 4 focuses on the involvement of free radicals in neurodegeneration. The topics discussed includes: the importance of nitric oxide metabolism in neurodegenerative pathways, mitochondrial function in neuronal aging and plasticity, and the role of vitagenes in the cellular stress tolerance during aging and neurodegeneration. The last, but not least section (section 5) returns to the concept of oxidative stress and is discussed within the scope of different pathologies and related processes. This section begins with pathologies as alcoholic fatty liver disease associated with obesity and age related macular degeneration and glaucoma. It ends with the role and importance of oxygen free radicals in liver preconditioning, myocardial ischemia-reperfusion and in an experimental model of choline deficiency. Bringing together so many internationally recognized authors was not an easy task. We are grateful to them, who worked very hard to produce reviews of high scientific quality. This concerted effort makes the book an updated reference in the involvement of reactive oxygen and nitrogen species in physiological and pathological processes. We are also grateful to Dr. S. G. Pandalai from Transworld Research Network, without whose support this project would have never been completed.

Available in PDF, EPUB and Kindle. Book excerpt: Oxygen free radicals and other reactive oxygen species are being postulated as causal agents in an increasing number of pathological conditions. Indeed, some investigators are suggesting that highly destructive reactive oxygen species are the final common path lead ing to tissue damage following a wide variety of insults including trauma, hypoxia, ischemia, hyperoxia, radiation, some toxins, and even strenuous athletic pursuits. But, as Robert Floyd points out, "Proof of the importance of oxygen free radicals and the oxidative damage they initiate depend on unequivocal evidence for the pres ence of free radicals and a clear association of their formation with the induction of the dysfunction of pathological conditions. " Since such proof does not come easily, there have been and will continue to be many controversies regarding the role played by reactive oxygen species in tissue damage. There have been many recent reviews of the chemistry and pos sible role of reactive oxygen species in many types of organ dys functions, tissue damage, degenerative diseases, and aging. This book is not such a review. Rather it presents for a diverse audience of physical-organic chemists, biochemists, medical researchers, and other investigators of pathophysiology, discussions of a variety of is sues important for understanding reactive oxygen species and their role in tissue damage.

Book excerpt: There has been an explosion of research related to free radicals and antioxidants in recent years, and hundreds of laboratories worldwide are actively involved in many as pects of free radicals, oxidative stress, and antioxidants. The literature on these topics in creases exponentially every year. Over the last few years, we have been fortunate to witness a widespread recognition of the important role of free radicals in a wide variety of pathological conditions including diseases such as atherosclerosis, cardiovascular and neurological diseases, ischemia, emphysema, diabetes, radiation injury, cancer, etc. In ad dition, many laboratories are studying the role of free radicals in the inexorable process of aging. Increased evidence involves free radicals with the etiology of various diseases, thereby suggesting the use of antioxidants as a viable therapeutic approach for the treat ment of free radical mediated pathologies. Despite these impressive developments, many important aspects of free radical and antioxidant research are open for investigation. It is important to understand the overall mechanisms involved in free radical mediated physiological and pathological conditions. This knowledge will undoubtedly lead to the development of new therapeutic approaches to prevent or control free radical related diseases. This book contains the proceedings of the NATO Advanced Study Institute (ASI) on "Free Radicals, Oxidative Stress, and Antioxidants: Pathological and Physiological Sig nificance," which was held in Antalya, Turkey from May 24-June 4, 1997.

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 have been implicated in a entire host of different human disease states, which suggests that although they may not have a pivotal causal role, they are involved in the perpetuation of disease. In recentyears, it has become evident that although free radicals most certainly do have this role in perpetuating inflammatory reactions, they have perhaps a far more important role in acting as second messenger systems to maintain normal cell function. It is theperturbations of these reactions which pose the most intriguing therapeutic challenges. This volume deals with various basic mechanisms of free radical processes and injury. The emphasis in each case is on potential therapeutic strategies developing fromthis new knowledge.

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.
