Oxidative Stress in Skeletal Muscle by Reznick,Packer,Sen,Holloszy,Jackson Pdf

Skeletal muscle consumes significant amounts of oxygen, and its oxygen flux increases significantly under conditions of exercise and muscle contraction. This makes the muscle vulnerable to oxidative stress since concomitantly with the increase of oxygen flow there is an increase of free oxygen radicals which are a byproduct of muscle respiration. A number of studies in the last decade have documented the involvement of free oxygen radicals in exercising muscles. The consequences of muscle oxidative stress have resulted mainly in increased muscle protein oxidation, elevation of lipid peroxidation, and depletion of muscle antioxidants. The mechanisms of this oxidative stress are under extensive investigation in laboratories around the world and are topics of the chapters in this volume. This book is intended for professionals who are interested in muscle function, physiology, pathophysiology and well-being, such as therapists, trainers and medical professionals as well as for researchers in the field of muscle physiology.

Aging Research in Yeast by Michael Breitenbach,S. Michal Jazwinski,Peter Laun Pdf

This volume includes contributions by the leading experts in the field of yeast aging. Budding yeast (Saccharomyces cerevisiae) and other fungal organisms provide models for aging research that are relevant to organismic aging and to the aging processes occurring in the human body. Replicative aging, in which only the mother cell ages while the daughter cell resets the clock to zero is a model for the aging of stem cell populations in humans, while chronological aging (measured by survival in stationary phase) is a model for the aging processes in postmitotic cells (for instance, neurons of the brain). Most mechanisms of aging are studied in yeast. Among them, this book discusses: mitochondrial theories of aging, emphasizing oxidative stress and retrograde responses; the role of autophagy and mitophagy; the relationship of apoptosis to aging processes; the role of asymmetric segregation of damage in replicative aging; the role of replication stress; and the role of the cytoskeleton in aging. Modern methods of yeast genetics and genomics are described that can be used to search for aging-specific functions in a genome-wide unbiased fashion. The similarities in the pathology of senescence (studied in yeast) and of cancer cells, including genome instability, are examined.

Oxidative Eustress in Exercise Physiology by James N. Cobley,Gareth W. Davison Pdf

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.

Redox Regulation in Skeletal Muscle Aging and Exercise by Brian McDonagh Pdf

Skeletal muscle represents the largest organ of the human body and comprises about 40% of total body mass in humans. Even in people who ‘age well’, there is a noticeable loss of muscle strength and function that accelerates dramatically after the age of 60, a major factor in the reduction in life quality for the aging population. One of the most effective interventions to maintain muscle mass and function is through exercise. Skeletal muscle generates reactive oxygen and reactive nitrogen (ROS/RNS) species in response to muscle contractions. The concentration and species of ROS/RNS generated can depend on the age and fitness of the individual, muscle fibre type and the intensity of the muscle contractions. ROS/RNS generate unique signaling cascades that are not only essential in skeletal muscle contraction and adaptation but also play a role in a wide array of cell processes including cell proliferation, protein synthesis/degradation, immune response and antioxidant defense. ROS/RNS generated by contractions are involved in a co-ordinated local response that is tightly controlled at all levels from generation to detoxification. This collection of original articles and reviews highlights investigations that measure different aspects of the redox response of skeletal muscle to aging and exercise.

Free Radicals in Exercise and Aging by Zsolt Radák Pdf

Explore the emerging field of free radical biology, exercise, and aging with this definitive reference. Free Radicals in Exercise and Agingaddresses the current debate regarding whether free radicals released during exercise accelerate the aging process. It explains how free radicals can serve as important regulators of aerobic processes, and it clarifies the importance of exercise in increasing the efficiency of the antioxidant and oxidative repair systems. Mounting research data indicate that free radicals are involved in a variety of physiological and pathophysiological processes. This book focuses on exercise-induced adaptation. In general, a person's ability to adapt to internal and external changes decreases during the aging process. However, by continually exposing the body to different challenges, regular exercise triggers an adaptation process that keeps the body and mind fit. Free Radicals in Exercise and Agingelucidates the role of free radical species in regulating this process. This text is also one of the first to provide an in-depth review of skeletal muscle oxidative stress and aging. This issue is pivotal because muscle serves such a critical role in mobility and normal life. Free Radicals in Exercise and Aging shares the most current understanding of how reactive oxygen species influence the biology of skeletal muscles. It explores some of the unique characteristics that skeletal muscle displays during aging, both in terms of free radical production and with regard to antioxidant systems. The implications of this research are far-reaching. Mutation of DNA is linked very closely to cancer, and if regular exercise improves the regulation of the antioxidant systems and the oxidative damage repair system, these mechanisms may be a very important tool against this deadly disease. This research-oriented text presents the latest information on the subject. It reviews and critiques current literature and provides critical information for exercise physiologists, sports medicine specialists, sport nutritionists, and gerontologists.

Handbook of Oxidants and Antioxidants in Exercise by C. Sen,L. Packer,O. Hänninen Pdf

Interest in the science of exercise dates back to the time of ancient Greece. Today exercise is viewed not only as a leisurely activity but also as an effective preventive and therapeutic tool in medicine. Further biomedical studies in exercise physiology and biochemistry reports that strenuous physical exercise might cause oxidative lipid damage in various tissues. The generation of reactive oxygen species is elevated to a level that overwhelms the tissue antioxidant defense systems resulting in oxidative stress. The Handbook of Oxidants and Antioxidants in Exercise examines the different aspects of exercise-induced oxidative stress, its management, and how reactive oxygen may affect the functional capacity of various vital organs and tissues. It includes key related issues such as analytical methods, environmental factors, nutrition, aging, organ function and several pathophysiological processes. This timely publication will be of relevance to those in biomedical science and was designed to be readily understood by the general scientific audience.

Skeletal Muscle Circulation by Ronald J. Korthuis Pdf

The aim of this treatise is to summarize the current understanding of the mechanisms for blood flow control to skeletal muscle under resting conditions, how perfusion is elevated (exercise hyperemia) to meet the increased demand for oxygen and other substrates during exercise, mechanisms underlying the beneficial effects of regular physical activity on cardiovascular health, the regulation of transcapillary fluid filtration and protein flux across the microvascular exchange vessels, and the role of changes in the skeletal muscle circulation in pathologic states. Skeletal muscle is unique among organs in that its blood flow can change over a remarkably large range. Compared to blood flow at rest, muscle blood flow can increase by more than 20-fold on average during intense exercise, while perfusion of certain individual white muscles or portions of those muscles can increase by as much as 80-fold. This is compared to maximal increases of 4- to 6-fold in the coronary circulation during exercise. These increases in muscle perfusion are required to meet the enormous demands for oxygen and nutrients by the active muscles. Because of its large mass and the fact that skeletal muscles receive 25% of the cardiac output at rest, sympathetically mediated vasoconstriction in vessels supplying this tissue allows central hemodynamic variables (e.g., blood pressure) to be spared during stresses such as hypovolemic shock. Sympathetic vasoconstriction in skeletal muscle in such pathologic conditions also effectively shunts blood flow away from muscles to tissues that are more sensitive to reductions in their blood supply that might otherwise occur. Again, because of its large mass and percentage of cardiac output directed to skeletal muscle, alterations in blood vessel structure and function with chronic disease (e.g., hypertension) contribute significantly to the pathology of such disorders. Alterations in skeletal muscle vascular resistance and/or in the exchange properties of this vascular bed also modify transcapillary fluid filtration and solute movement across the microvascular barrier to influence muscle function and contribute to disease pathology. Finally, it is clear that exercise training induces an adaptive transformation to a protected phenotype in the vasculature supplying skeletal muscle and other tissues to promote overall cardiovascular health.

Stress Adaptation, Prophylaxis and Treatment by Dipak K. Das Pdf

Stress reaction is likely to play a crucial role in a variety of degenerative diseases including cancer and cardiovascular diseases. The process of stress adaptation may appear to be simple, but in reality this is a very complex process and we are only beginning to understand the mechanism of adaptation. In January, 1998, scientists from around the world assembled to discuss the potential applicability of the concept of stress adaptation in the clinical arena. This volume contains original research papers presented on this subject during the conference Stress Adaptation, Prophylaxis and Treatment held in Calcutta, India, and serves as an up-to-date source of information for scientists, as well as clinicians interested in applying the concept of stress adaptation to the cure of diseases.

Mitochondria in Skeletal Muscle Health, Aging and Diseases by Gilles Gouspillou,Russell T. Hepple Pdf

Skeletal muscle is the most abudant tissue of the human body, making up to 40 to 50% of the human body mass. While the importance of optimal muscle function is well recognized in the athletic field, its significance for general health is often underappreciated. In fact, the evidence that muscle mass, strength and metabolism are essential for our overall health is overwhelming. As the largest protein reservoir in the human body, muscles are essential in the acute response to critical illness such as sepsis, advanced cancer, and traumatic injury. Loss of skeletal muscle mass has also been associated with weakness, fatigue, insulin resistance, falls, fractures, frailty, disability, several chronic diseases and death. As a consequence, maintaining skeletal muscle mass, strength and metabolism throughout the lifespan is critical to the maintenance of whole body health. Mitochondria are fascinating organelles regulating many critical cellular processes for skeletal muscle physiology, including for instance energy supply, reactive oxygen species production, calcium homeostasis and the regulation of apoptosis. It is therefore not surprising that mitochondrial dysfunction has been implicated in a large number of adverse events/conditions and pathologies affecting skeletal muscle health. While the importance of normal mitochondrial function is well recognized for muscle physiology, there are important aspects of mitochondrial biology that are still poorly understood. These include mitochondrial dynamics (fusion and fission processes), morphology and processes involved in mitochondrial quality control (mitophagy). Defining the mechanisms regulating these different aspects of mitochondrial biology, their importance for muscle physiology, as well as the interrelations will be critical for expanding understanding of the role played by mitochondria in skeletal muscle physiology and health. The present research topic provides readers with novel experimental approaches, knowledge, hypotheses and findings related to all aspects of mitochondrial biology in healthy and diseased muscle cells.
