Oxidative Eustress in Exercise Physiology (Oxidative Stress and Disease #47)

by James N. Cobley

Oxidative Eustress in Exercise Physiology unravels key physiological responses and adaptations to different redox-regulated exercise paradigms at the cell, tissue, and whole-body level in model systems and humans in health and disease. While the mechanistic details are still unclear, key intracellular redox indices seem to be dysregulated with age. Consequently, beneficial molecular responses to acute endurance exercise decline in older individuals. Recent research suggests that manipulating mitochondrial redox homeostasis by supplementing with the mitochondria-targeted coenzyme Q10 for six weeks markedly improves physical function in older adults; i.e. it may be possible to maximise the benefits of exercise by manipulating the redox environment. The research described in this book suggests that significant translational potential exists with respect to cardiovascular disease, neurodegeneration and cancer. An international team of researchers documents the importance of redox biology in health and disease, especially when exercise is a clinically useful tool for the treatment of many diseases and conditions. Features Defines essential redox biology reactions and concepts in exercise physiology Assesses key redox parameters in an in vivo human exercise context Identifies the challenges, opportunities and boundaries of current knowledge Includes a critique of the underlying mechanisms Summarises examples of translationally important research relating to disease states Related Titles Draper, N. & H.

Oxidative Neural Injury

by Sigrid C. Veasey

This book examines the current evidence and research supporting the importance of oxidative injury in selected animal models of both neurodegenerative diseases and neural injury. Each chapter discusses oxidative injury in a selected model, analyzing the major cellular mechanisms that underpin the progression of neural injury. In addition to the analysis of these models, each chapter's purpose is to not only relate, but to also contrast the specific injury across models as a way of identifying the common and unique pathways of oxidative neural injury. Through this, each author presents possible fertile future directions for translational research for the identification of possible therapeutics.

Oxidative Stress Mechanisms and their Modulation

by Mohinder Bansal Naveen Kaushal

Research over the years has demonstrated that free radicals mediated oxidative stress lies at the helm of almost all patho-physiological phenomena. These findings emphasize on the need to understand the underlying molecular mechanism(s) and their critical role in the pathogenesis. This book aims to focus on these areas to provide readers a comprehensive outlook about the major redox sensitive pathways and networks involved in various disease conditions. In the first chapter of the book, basic information about the oxidative stress, its generation, its biomarkers and its role in body are discussed. In the next three chapters, the role of oxidative stress in various pathologies ranging from neurological disorders, to cardiovascular diseases, cancers, metabolic diseases and ageing have been described. Chapter 5 cumulatively describes the most important molecular signaling pathways that are affected by reactive oxygen species (ROS). These are the mechanisms which are common denominators in various pathological states. In the next part of the book, various antioxidant strategies to target and mitigate ROS have been discussed with details on the mechanisms. Selenium, being the research focus and interest of the authors for years, the role of selenium as an antioxidant as part of selenoproteins has been included in the book. Finally, the book culminates with authors' perspective on the future of the redox biology field. Throughout the book, efforts have been made to use simplified language and suitable figures for ease to understand the contents. Although the authors have tried to touch on all the different aspects of oxidative stress in detail, the fact that it is a continuously growing field with updates coming every day, there might be some areas which might not be described in depth. This book is designed for students, young scientists to get acquainted with the redox biology. Overall, this book is a reference to understand the redox regulation of cellular signaling pathways involved in pathogenesis.

They address how these effects can be attenuated, and examine whether antioxidants and natural micronutrients, such as those found in Gingko biloba, green tea, blueberries, and grape seed extract, can play a role. The book includes various ways research is getting to the core of neurodegenerative disease, including the use of proteomics, comparisons to related diseases, and examinations at the cellular and molecular levels.

Oxidative Stress and Cardiorespiratory Function

by Mieczyslaw Pokorski

Cardiorespiratory function is prominently affected by oxidative stress. Cigarette smoking is the archetype of oxidative and nitrative stress and free radical formation. New adverse effects of smoking keep on propping up in research. The chapters provide the comprehensive view of new developments in this area regarding cardiovascular and lung function and muscle catabolism. Alterations in inflammatory cytokines and proteins as well as degradation of muscle proteins due to smoking, by far unrecognized, caused by oxidative stress also are presented. Much less is known about the effect of cognitive stress on vagally-mediated cardiorespiratory function and surprisingly, on vagal immune pathway. The experimental studies also show that clinically important meconium aspiration syndrome contains an oxidative trait which is amenable to antioxidative treatment. This volume creates a source of information on the damaging role of oxidative stress in cardiorespiratory function that has by far not been available.

Oxidative Stress and Free Radical Damage in Neurology

by Natan Gadoth Hans Hilmar Göbel

The role of free radicals and oxidative stress in neurological disorders has only recently been recognized, leaving clinical neurologists to seek in vain for information on the subject even in major textbooks. What published information there is may consist of brief reminders of the possible association of superoxidase dismutase with familial amyotrophic lateral sclerosis and nitrous oxide with migraine. With luck they may also find information on the purported role of free radicals in the pathogenesis of traumatic brain injury. Oxidative Stress and Free Radical Damage in Neurology sets the record straight, focusing on clinical and research issues regarding the interplay of free radicals and the human nervous system. Crucially, the chapters cover numerous antioxidants and their possible therapeutic role in neurological disorders. Key illnesses such as epilepsy, multiple sclerosis and Parkinson's are analyzed, and chapters also examine more general issues such as the link between free radicals and inflammation of the central nervous system. Clinicians and laboratory researchers alike will find that this book augments their understanding not only of the widespread involvement of free radicals in the central nervous system but also of some uncertainties surrounding whether free radical damage in neurology plays a primary or secondary role.

The book offers fascinating insights into how organisms work and how they evolve to sustain their physiological functions under a vast array of environmental conditions.

Oxidative Stress and Inflammation in Non-communicable Diseases - Molecular Mechanisms and Perspectives in Therapeutics

by Jordi Camps

Oxidative stress and inflammation underpin most diseases; their mechanisms are inextricably linked. For example, chronic inflammation is associated with oxidation, anti-inflammatory cascades are linked to decreased oxidation, increased oxidative stress triggers inflammation and redox balance inhibits the inflammatory cellular response. Whether or not oxidative stress and inflammation represent the causes or the consequences of cellular pathology, they contribute significantly to the pathogenesis of non-communicable diseases. The incidence of obesity and other related metabolic disturbances are rising, as are age-related diseases due to progressively aging populations. Interrelations between the mechanisms of oxidative stress and of inflammatory signaling and metabolism are, in the broad sense of energy transformation, being increasingly recognized as part of the problem in non-communicable diseases. The book Oxidative Stress and Inflammation in Non-communicable Diseases: Molecular Mechanisms and Perspectives in Therapeutics is an update on the latest research on the molecular basis of non-communicable diseases and the search for possible therapeutic alternatives. The authors of this monograph are experts in their field and the book as a whole, provides an overview of the biochemical alterations underlying diseases such as cardiovascular disease, cancer, obesity, renal disease, neurological diseases and diabetes, emphasizing those aspects that they share in common. We hope that this book will be useful for researchers in biomedicine and also for physicians interested in finding the root causes of the disease, as well as for post-graduate students in biochemistry, molecular biology, nutrition or medicine.

Oxidative Stress and Redox Regulation

by Ursula Jakob Dana Reichmann

Many physiological conditions such as host defense or aging and pathological conditions such as neurodegenerative diseases, and diabetes are associated with the accumulation of high levels of reactive oxygen species and reactive nitrogen species. This generates a condition called oxidative stress. Low levels of reactive oxygen species, however, which are continuously produced during aerobic metabolism, function as important signaling molecules, setting the metabolic pace of cells and regulating processes ranging from gene expression to apoptosis. For this book we would like to recruit the experts in the field of redox chemistry, bioinformatics and proteomics, redox signaling and oxidative stress biology to discuss how organisms achieve the appropriate redox balance, the mechanisms that lead to oxidative stress conditions and the physiological consequences that contribute to aging and disease.

Oxidative Stress in Cancer Biology and Therapy

by Kenneth J. Dornfeld Koyamangalath Krishnan David Gius Douglas R. Spitz

During the last 30 years it has become clearly evident that oxidative stress and free radical biology play key roles in carcinogenesis, cancer progression, cancer therapy, and normal tissue damage that limits treatment efficacy during cancer therapy. These mechanistic observations have led to the realization that free radical biology and cancer biology are two integrally related fields of investigation that can greatly benefit from cross fertilization of theoretical constructs. The current volume of scientific papers was assembled under the heading of Oxidative Stress in Cancer Biology and Therapy in order to stimulate the discussion of how the knowledge gained in the emerging field of oxidative stress in cancer biology can be utilized to more effectively design interventions to enhance therapeutic responses while causing fewer treatment limiting complications. The chapters contained in this volume provide highly informative emerging perspectives on how that selective enhancement of oxidative stress in cancerous tissues can be used as a target for enhancing therapeutic outcomes as well as how selective inhibition of oxidative stress could spare normal tissue damage and inhibit carcinogenesis. In this regard, the book represents an outstanding resource for both basic and translational scientists as well as clinicians interested in the field of oxidative stress and cancer therapy.

Oxidative Stress in Human Reproduction

by Ashok Agarwal Rakesh Sharma Damayanthi Durairajanayagam Stefan S. Du Plessis Sajal Gupta Avi Harlev Sandro C. Esteves Gulfam Ahmad Siew May Wang

This SpringerBrief discusses the role of oxidative stress in the reproductive system. The book reviews endogenous sources, methods of determining its levels in body fluid/tissues, the physiological roles of ROS, as well as its negative effects on the human reproductive processes. Also discussed are multiple extrinsic factors that could induce oxidative stress in the reproductive system. This brief covers various clinical pathologies related to the reproductive system that arise from or produce oxidative stress, both in the male and female. The use of antioxidants as a therapeutic measure to keep ROS levels in check are highlighted, describing the outcome of various clinical studies involving antioxidant supplementation in infertile patients. Infertility is a global disease that affects 15-25% of all couples, and oxidative stress arising from a multitude of sources has been implicated as one of the major contributing factors to the decline in human fertility. As such, this book provides an up-to-date review on the significance of ROS in human reproduction.

Oxidative Stress in Lung Diseases: Volume 1

by Sajal Chakraborti Tapati Chakraborti Salil Kumar Das Dhrubajyoti Chattopadhyay

This first volume of the comprehensive, two-volume work on oxidative stress in lung disease introduces the molecular mechanisms, and the role of oxidants in the progression of different lung diseases. The lungs of humans and animals are under constant threat from oxidants from either endogenous (e.g. in situ metabolic reactions) or exogenous sources (e.g. air pollutants). Further, oxidative stress causes the oxidation of proteins, DNA and lipids, which in turn generates secondary metabolic products. The book consists of sections, each focusing on different aspects of oxidant-mediated lung diseases. As such it is a unique reference resource for postgraduate students, biomedical researchers and also for the clinicians who are interested in studying and understanding oxidant-mediated lung diseases. The second volume will incorporate other aspects of oxidant-mediated lung diseases, including prevention and therapeutics.
