Download or read book Free Radical Reactions in Medicine written by Janos Feher and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book aims to provide a concise review of the medical aspects of free radical reactions. Until now, there have been extensive reviews of the subject in a physiological, pathophysiological and biochemical context. Here, however, the authors concentrate on the biology of free radical reactions as relevant to medical practice, emphasizing that the topic is not just a branch of basic science. Consequently, a short introduction on chemical and biological aspects is followed by a detailed discussion of the role played by free radical reactions in the pathogenesis and development of several human diseases and in therapeutic possibilities. The summary of data from the literature is supplemented by the authors' own experimental results. The presentation will help medical researchers to notice so far unknown connections among several diseases and to make them aware of the existance of the so-called "free radical diseases".

This book was released on 2012-12-06 with total page 461 pages. Available in PDF, EPUB and Kindle. 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: 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: This monograph contains the proceedings of a symposium entitled, "Tissue Hypoxia and Ischemia," which was held at the Annenberg Center of the University of Pennsylvania on August 13 and 14, 1976. The symposium was jointly sponsored by the following groups at the University of Pennsylvania: the Respiratory Physiology Group of the Department of Physio logy, the Cardiopulmonary Section of the Department of Medicine, the Johnson Research Foundation, the Cerebrovascular Research Center of the Department of Neurology, the Head Injury Center of the Department of Neurosurgery, the. Institute for Environ mental Medicine, and the International Society on Oxygen Transport to Tissues. Its purpose was to promote an interdisciplinary discussion of oxygen sensors in various tissues and their mechanism of action as well as to examine the deleterious effects of hypoxia and ischemia with special reference to the brain. There were four sessions, one on the biochemistry of physi ologic oxygen sensors, two on the mechanism of oxygen sensing in tissues and one on the circulatory and metabolic aspects of cerebral hypoxia and ischemia.
Download or read book Oxygen Radicals in Biology and Medicine written by Michael Simic and published by Springer Science & Business Media. 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 and Iron written by Martyn C. R. Symons and published by . This book was released on 1998 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: This concise monograph describes a variety of important reactions of iron in biological free-radical reactions. It presents both a chemical and a biochemical perspective of the topic, but at the same time unifies ideas where possible. Iron plays a key role in biological life processes, as acatalayst enabling us to use oxygen to generate the heat and chemical energy that drives life. When iron is not properly controlled within the body it can cause damage by making free radicals. The authors present a chemical and biomedical perspective of how reactions of iron complexes and freeradicals may contribute to human health and disease, especially in reactions of oxygen and hydrogen peroxide.
Download or read book Excited States and Free Radicals in Biology and Medicine written by R. V. Bensasson and published by . This book was released on 1993 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Free Radicals in Food written by Michael J. Morello and published by . This book was released on 2002 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Free Radicals in Food: Chemistry, Nutrition, and Health presents recent developments in free radical chemistry as it pertains to food systems, antioxidants, and nutritional biochemistry and health. This book intends to illustrate the potential chemical links between food and health. The book is organized into three main sections: Food Chemistry, Antioxidants, and Nutritional Biochemistry and Health. Chapters in the Food Chemistry section cover free radical participation in Maillard reactions, emulsions and lysozymes, milk, meat, and extruded grains. This section also addresses detection of radicals by ESR and spin trapping techniques. Chapters in the Antioxidant section cover phenolic and polyphenols from seeds and tea, tannins, and isoflavonoids. Chapters in the Nutritional Biochemistry and Health section cover the influence of food antioxidants and radical damaged ingredients on oxidases, colon carinogenesis, atherosclerosis, and liver epithelial RL34 cells. The ability of specific food components and supplements to intervene in free radical reactions is believed to play a significant role in their ability to promote health and ameliorate disease. Free Radicals in Food presents specific chemical evidence to support these hypotheses.
Download or read book Free Radical Induced DNA Damage and Its Repair written by Clemens Sonntag and published by Springer Science & Business Media. This book was released on 2006-03-20 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: The free-radical chemistry of DNA had been discussed in some detail in 1987 in my book The Chemical Basis of Radiation Biology. Obviously, the more recent developments and the concomitant higher level of understanding of mechanistic details are missing. Moreover, in the living cell, free-radical DNA damage is not only induced by ionizing radiation, but free-radical-induced DNA damage is a much more general phenomenon. It was, therefore, felt that it is now timely to review our present knowledge of free-radical-induced DNA damage induced by all conceivable free-radical-generating sources. Originally, it had been thought to include also a very important aspect, the repair of DNA damage by the cell’s various repair enzymes. Kevin Prise (Cancer Campaign, Gray Laboratory, L- don) was so kind to agree to write this part. However, an adequate description of this strongly expanding area would have exceeded the allocated space by much, and this section had to be omitted. The directors of the Max-Planck-Institut für Strahlenchemie (now MPI für Bioanorganische Chemie), Karl Wieghardt and Wolfgang Lubitz, kindly allowed me to continue to use its facilities after my retirement in 2001. Notably, our - brarian, Mrs. Jutta Theurich, and her right-hand help, Mrs. Rosemarie Schr- er, were most helpful in getting hold of the literature. I thank them very much. Without their constant help, this would have been very difficult indeed.
Download or read book Free Radicals in Biology and Environment written by F. Minisci and published by Springer Science & Business Media. 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Free Radicals from Basic Science to Medicine written by POLI and published by Birkhäuser. This book was released on 2011-09-26 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: Free radical-mediated reactions have been well known in chemistry and physical chemistry for many years. Applying this knowledge to living organisms, biochemists have shown that reactive free radicals are formed at many intracellular sites during normal metabolism, and they have started to suggest possible roles in various pathological processes and conditions, for example in radiation damage, in the metabolism of xenobiotics, in carcinogenesis and in metabolic disorders. At present, a large and relevant mass of experimental evidence supports the view that reactive free radicals are involved in the pathogenesis of several diseases and syndromes. This literature has captured the attention and interest of people involved in the biomedical field. Exciting developments in radical research are probable in the near future, establishing a greater interaction between basic science research and medicine. While the task of defining the involvement of free radicals in human pathology is difficult, it is nonetheless extremely important that such interaction be fulfilled as soon as possible. These were the considerations motivating us during the organization of the VI Biennial Meeting of the International Society for Free Radical Research held in Torino, Italy, in June 1992, and also during the preparation of this book. Experts in the various aspects of free radical research were invited to participate in the Torino Meeting and to contribute chapters for this volume.
Download or read book Free Radicals in Medicine written by Radu Olinescu and published by Nova Publishers. This book was released on 2002 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: The role of reactive oxygen species and other free radicals in normal and disease processes has become a major area of interest in the medical scientific community. In the past 30 years, this area of study has advanced from outright rejection, to general acceptance, to intense study. While there is still some dispute as to the exact role of these highly reactive molecules in pathology, it is clear that they are present in and influence many biological processes. This book provides an overview of the possible biological effects of reactive oxygen species and other free radicals with an emphasis on pathology. The various types of free radicals that may affect the body are discussed along with the potential sources of free radicals, both internal and external to the body. The extensive defenses the body raises against the effects of these molecules in the form of enzymatic and non-enzymatic antioxidants is reviewed. A variety of conditions in which free radicals have been proposed to play a role are discussed. These include the physiological effects of oxygen stress in aging, exercise, and pregnancy. Pathologic conditions discussed include cancer, liver cirrhosis, respiratory problems, and others.
