Reactive Oxygen Species in Chemistry, Biology, and Medicine by A. Quintanilha Pdf

A NATO Advanced Study Institute on "Oxygen Radicals in Biological Systems: Recent Progress and New Methods of Study" was held in Braga, Portugal between Sep tember 1 and September 14, 1985, in order to consider the basic chemistry and biochem istry of activated oxygen (both radical and non-radical species) and their effect in biolog ical systems. This book summarizes the main lectures given at this meeting. While there is no attempt to cover all the major topics in the expanding subject of oxidative mechanisms in biology, an effort has been made to provide overviews on some key aspects of this field. The authors have attempted to convey a clear picture of both what is known and what remains unclear in their respective subjects. Not only are some of the techniques used for detecting activated oxygen species described, but also their strengths and limi tations. The chemistry of many of these species is discussed and the biological and/or pathological implications are carefully reviewed. The medical and therapeutic aspects of some of the well established pathways of damage and protection are analyzed. It is our hope that the material included in this book might be useful for both researchers and teachers at the graduate level. The success of this meeting was to a large extent due to the tireless committment of Professor Alberto Amaral and Dr. Concei~a:o Rangel; without their outstanding efforts in dealing with all the aspects of the organization, this summer school would not have been possible.

Oxygen Radicals in Biology and Medicine by Michael Simic Pdf

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.

Reactive Oxygen Metabolites by Manfred K. Eberhardt Pdf

In recent years, the field of radical chemistry has undergone explosive growth. Although its roots lie in organic chemistry, the implications of its findings are having enormous impact in a broad range of disciplines, and we now have evidence for radical involvement in over 100 diseases. As important as this is, however, the subject of radicals and reactive oxygen metabolites (ROMs) is complex and barely touched upon in the curriculum of medical schools. Reactive Oxygen Metabolites brings the subject within the grasp of even those with little preparation in chemistry. From the basic chemistry of radicals through the pathology, the author provides a clear and thorough introduction to ROMs and their importance to human health and disease. Exhaustively researched and referenced, this highly readable work will give you the ability to critically analyze and evaluate many pathological problems arising from the chemistry of ROMs and reduce them to their lowest common denominator. It is the ideal vehicle for people who need to understand the importance of reactive oxygen and nitrogen species in human health and disease but have neither the time, the inclination, nor perhaps the background to work their way through the mountain of original literature.

Free Radical Medicine and Biology by Anonim Pdf

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.

Oxidants in Biology by Giuseppe Valacchi,Paul A. Davis Pdf

Oxidants, like other aspects of life, involves tradeoffs. Oxidants, whether intentionally produced or by-products of normal metabolism can either mediate a variety of critical biological processes but when present inappropriately cause extensive damage to biological molecules (DNA, proteins, and lipids). These effects can lead to either damage that is a major contributor to aging and degenerative diseases (or to other diseases such as cancer, cardiovascular disease, immune-system decline, brain dysfunction, and cataracts) or normal physiological function- tissue repair, defense against pathogens and cellular proliferation. On the other hand the body is equipped with a complex antioxidant/oxidant handling system which includes both enzymatic and nonenzymatic (i.e. small molecules such as flavonoids, ascorbate, tocopherol, and carotenoids) produced endogenously or derived from the diet. This book focuses on how the same molecules can have favorable or noxious effects depending on location, level and timing. Each chapter focuses on one particular molecule or oxidant/antioxidant system and provides a state of the art review of the current understanding regarding both positive and negative actions of the system under review.

Redox-Active Therapeutics by Ines Batinić-Haberle,Júlio S. Rebouças,Ivan Spasojević Pdf

This essential volume comprehensively discusses redox-active therapeutics, focusing particularly on their molecular design, mechanistic, pharmacological and medicinal aspects. The first section of the book describes the basic aspects of the chemistry and biology of redox-active drugs and includes a brief overview of the redox-based pathways involved in cancer and the medical aspects of redox-active drugs, assuming little in the way of prior knowledge. Subsequent sections and chapters describe more specialized aspects of central nervous system injuries, neurodegenerative diseases, pain, radiation injury and radioprotection (such as of brain, lungs, head and neck and erectile function) and neglected diseases (e.g., leishmaniasis). It encompasses several major classes of redox-active experimental therapeutics, which include porphyrins, salens, nitrones, and most notably metal-containing (e.g., Mn, Fe, Cu, Zn, Sb) drugs as either single compounds or formulations with nanomaterials and quantum dots. Numerous illustrations, tables and figures enhance and complement the text; extensive references to relevant literature are also included. Redox-Active Therapeutics is an invaluable addition to Springer’s Oxidative Stress in Applied Basic Research and Clinical Practice series. It is essential reading for researchers, clinicians and graduate students interested in understanding and exploring the Redoxome—the organism redox network—as an emerging frontier in drug design, redox biology and medicine.

Vitamin E by Etsuo Niki Pdf

Vitamin E was discovered in 1922 by Evans and Bishop as an essential micronutrient for reproduction in rats. The active substance was isolated in 1936 by Evans and was named tocopherol, although the tocopherols and tocotrienols are actually a group of eight isomeric molecules that are characterized by a chromanol ring structure and a side chain. Providing an overview of the state-of-the-art of the chemistry of vitamin E, this book reflects the issues stemming from the complexity of the role and actions in vivo as well as in vitro. It summarizes information on the properties and function of vitamin E, the current understanding of the advantages and limitations of it, and also its application in promotion of health and prevention of diseases. Based on sound, solid scientific evidence, this is a timely addition to the literature as the centennial anniversary of the discovery of this important vitamin approaches.

Oxidative Stress: Diagnostic Methods and Applications in Medical Science by Pawan Kumar Maurya,Pranjal Chandra Pdf

This book discusses the importance of oxidative stress, related biomarkers, and its diagnostic methods including bio-analytical and advanced detection systems. Oxidative stress is associated with diminished capacity of a biological system to overcome the overproduction of reactive oxygen species. Since oxidative stress has been suggested as a causative factor in many diseases, its prevention is vital, and there is an urgent need for oxidative stress monitoring using in vitro and in vivo models. Interdisciplinary approaches have lead to the development of various oxidative stress monitoring models for real-world clinical and biomedical applications. The development of such methods requires a broad understanding of biology, chemistry, molecular biology, immunology and microbiology. As such, the book is a valuable resource for students, researchers and clinicians interested in the fundamental as well as applied aspects of oxidative stress associated diseases.

Free Radicals in Biology and Medicine by Barry Halliwell,John M. C. Gutteridge Pdf

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.

Reactive Oxygen Species (ROS) in Living Cells by Filip Cristiana,Albu Elena Pdf

Oxygen represents only 20% of the Earth's atmosphere, yet it is vital for the survival of aerobic organisms. There is a dark part of the use of oxygen that consists in generating reactive species that are potentially harmful to living organisms. Moreover, reactive oxygen species can combine with nitrogen derivatives and generate many other reactive species. Thus, living organisms are continuously assaulted by reactive species from external or internal sources. However, the real danger comes in the case of high concentrations and prolonged exposure to these species. This book presents an image of the mechanisms of action of reactive species and emphasizes their involvement in diseases. Inflammation and cancer are examined to determine when and how reactive species turn the evolution of a benign process to a malignant one. Some answers may come from recent studies indicating that reactive species are responsible for epigenetic changes.

Reactive Sulfur Species in Biology and Medicine by John P Toscano,Vinayak S Khodade Pdf

Hydrogen sulfide (H2S) is a naturally occurring signaling molecule produced in vivo and plays a pivotal role in regulating a wide array of physiological processes. Additionally, emerging findings have illuminated that many of the biological effects initially attributed to H2S may actually stem from other reactive sulfur species (RSS), including hydropersulfides (RSSH) and various higher-order polysulfur species (RSSnH, RSSnR, and HSnH, where n > 1). These studies have underscored the contributions of these species to essential cellular processes, such as the efficient scavenging of reactive oxygen species and electrophiles, and their influence on mitochondrial function. Nonetheless, the chemistry of RSS remains challenging due to their inherently reactive nature, and their precise measurement within biological systems continues to pose a formidable challenge. This compilation of reprints focuses on recent advancements in the field of H2S/RSS chemical biology. It encompasses original research studies and comprehensive reviews, all geared towards exploring the therapeutic potential of H2S/RSS donors in the treatment of various conditions, including cancer, neurological disorders, and cardiovascular disease. Furthermore, it delves into the molecular mechanisms and physiological roles played by RSS along with the development of methodologies for quantifying and measuring the distribution of RSS within biological systems.

Reactive Oxygen Species in Biology and Human Health by Shamim I. Ahmad Pdf

Unlike other narrowly focused books, Reactive Oxygen Species in Biology and Human Health provides a comprehensive overview of ROS. It covers the current status of research and provides pointers to future research goals. Additionally, it authoritatively reviews the impact of reactive oxygen species with respect to various human diseases and discusses antioxidants and other compounds that counteract oxidative stress. Comprised of seven sections, the first section describes the introduction, detection, and production of ROS, emphasizing phenolic compounds and vitamin E for their abilities to act as antioxidants. This section also highlights the role of lipoprotein-associated oxidative stress. Section two addresses the importance of iron accumulation in the brain resulting in the development of a group of neurodegenerative disorders (NDs) and identifies several causative genes for neurodegeneration with brain iron accumulation (NBIA) associated with Parkinsonism-related disorders. The third section discusses a number of NDs, including amyotrophic lateral sclerosis (ALS), Alzheimer’s disease (AD), Huntington's disease (HD), epilepsy, and multiple sclerosis (MS). Section four addresses autoimmune diseases caused by ROS, including asthma, autoimmune liver diseases, rheumatoid arthritis, thyroid disease, primary biliary cirrhosis, and systemic lupus. Section five analyzes a number of different cancers, including lung cancer, breast cancer, and melanoma, along with possible treatment regimens. Section six discusses cardiovascular diseases (CVDs) induced by ROS, presents the ROS-associated complex biochemical processes inducing inflammation as an important cause of CVDs, and explains the roles carotenoids play in preventing CVDs. The final section addresses other human diseases induced by oxidative stress, including sickle cell disease, nonalcoholic steatohepatitis, retinopathy, fibromyalgia, chronic obstructive pulmonary disease, asthma, pulmonary hypertension, infertility, and aging of human skin.
