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.

The brain is crucial for the regulation of whole-body metabolism and behavior. The pancreas-derived hormone insulin modulates brain function and affects energy metabolism as well as cognition. This is partially achieved by modulating several types of brain cell populations including those relevant to satiety and reward. Importantly, brains of Alzheimer ́s disease patients exhibit a signature of brain insulin resistance with perturbed brain metabolism. This book will cover the basics of insulin signaling in the brain and will describe concepts of insulin resistance, a feature of type 2 diabetes. Moreover insulin ́s effect on cognitive function will be pointed out and the association between brain insulin resistance and neurodegenerative diseases discussed. Additionally, potential behavioral and pharmacological concepts which can affect brain insulin signaling will be summarized. Key Features: Summarizes insulin and the closely related IGF-1 receptor signaling Depicts concepts of insulin resistance Highlights the importance of conserved brain insulin signaling for brain function, metabolism, and behavior Describes potential behavioral and pharmacological approaches to support brain insulin signaling

Mitochondrial research has exploded over the last ~150 years. This book gives an amazing view on a conceptual change in our understanding of mitochondrial biology. It becomes clear that mitochondria are extremely dynamic in nature, controlling life at multiple levels. Mitochondria rule energy conversion, adapt cells well to changing stress and nutrient conditions, and regulate many cellular processes including immunity. The dynamic nature of mitochondria occurs at an intramitochondrial level but also includes its ability to interact with other organelles and to modulate multiple signalling pathways. It is thus not surprising that alterations or inabilities to ensure this dynamic behaviour is linked to ageing and human diseases. The following sections give an updated view on mitochondria: Mitochondrial ultrastructure: molecular mechanisms shaping the inner membrane Mitochondrial cristae and lipid dynamics: from super-resolution microscopy to lipid-OXPHOS interplay Mitochondrial control of cellular homeostasis: from redox signalling to interorganellar contact sites Mitochondria in health and disease: from mtDNA release to Complex I assembly Advanced methods in mitochondrial biology and metabolism research Integrative view on mitochondrial research and outlook The field of mitochondrial research has always been full of surprises and has helped science to advance tremendously. It developed hand in hand with landmark developments in technology, such as super-resolution microscopy (nanoscopy), and is currently influencing an increasing number of scientific disciplines. There is still much ‘new’ to find out about this ‘old’ organelle and I think that you can find interesting and also unexpected aspects of mitochondrial biology in this book. I hope the book will enhance your scientific curiosity and inspire your own research.

To produce energy, aerobic organisms transform oxygen molecules into water. This reductive mechanism yields toxic radical intermediates, collectively known as reactive oxygen species (ROS). Paradoxically, these physiological processes entail the production of potentially damaging species. Evolution has turned this apparent disadvantage into an opportunity for transmitting information. As a result, redox signaling within the cell is an efficient exquisitely organized process. A key element for its regulation is the physical separation of sources and targets into different cell compartments. Peroxiporins, H2O2 transporting proteins spanning biological membranes, distribute the signal from emitters to receptors. Thus, these channels are strategically situated in the thin line between life and death, guaranteeing adequate but safe signaling. Key Features: - Provides a brief history of the discovery and characterization of peroxiporins - Reviews key findings on hydrogen peroxide transport across biological membranes - Discusses the cartography of redox signaling in crowded cells - Includes lavish illustrations and comprehensive images to facilitate teaching - Highlights recent findings, outstanding controversies and open questions

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.

The New York Times bestselling book coauthored by the Nobel Prize winner who discovered telomerase and telomeres' role in the aging process and the health psychologist who has done original research into how specific lifestyle and psychological habits can protect telomeres, slowing disease and improving life. Have you wondered why some sixty-year-olds look and feel like forty-year-olds and why some forty-year-olds look and feel like sixty-year-olds? While many factors contribute to aging and illness, Dr. Elizabeth Blackburn discovered a biological indicator called telomerase, the enzyme that replenishes telomeres, which protect our genetic heritage. Dr. Blackburn and Dr. Elissa Epel's research shows that the length and health of one's telomeres are a biological underpinning of the long-hypothesized mind-body connection. They and other scientists have found that changes we can make to our daily habits can protect our telomeres and increase our health spans (the number of years we remain healthy, active, and disease-free). The Telemere Effect reveals how Blackburn and Epel's findings, together with research from colleagues around the world, cumulatively show that sleep quality, exercise, aspects of diet, and even certain chemicals profoundly affect our telomeres, and that chronic stress, negative thoughts, strained relationships, and even the wrong neighborhoods can eat away at them. Drawing from this scientific body of knowledge, they share lists of foods and suggest amounts and types of exercise that are healthy for our telomeres, mind tricks you can use to protect yourself from stress, and information about how to protect your children against developing shorter telomeres, from pregnancy through adolescence. And they describe how we can improve our health spans at the community level, with neighborhoods characterized by trust, green spaces, and safe streets. The Telemere Effect will make you reassess how you live your life on a day-to-day basis. It is the first book to explain how we age at a cellular level and how we can make simple changes to keep our chromosomes and cells healthy, allowing us to stay disease-free longer and live more vital and meaningful lives.

This book aims to present the age-related alterations in redox signaling networks and their diagnostic biomarkers in aging cells using multidisciplinary approach. Establishing sensitive and specific biomarkers of dynamic redox homeostasis is crucially important in the development of effective antiaging and senolytic interventions. Recent years have seen tremendous advances in the understanding of redox signaling events which highlight the process of aging and age-related pathologies. A major challenge in biological aging research is developing reliable biomarkers to determine the consequences of disrupted redox signaling networks long before the clinical diagnosis of age-related diseases is made. Therefore, we have chosen to concentrate on aging-induced aberrant redox signaling networks, their biomarkers, and pathological consequences in this book. Although oxidation is a natural metabolic process, the imbalance in the level of oxidants and antioxidants causes oxidative stress and eventually leads to inflammatory conditions, diabetes, neurodegenerative diseases, and cancer. Novel redox-sensitive biomarkers for the evaluation of aging-induced proteinopathies such as amyloid ß and tau proteins in Alzheimer's disease, α-synuclein in Parkinson's disease, and islet amyloid polypeptides in type 2 diabetes mellitus recently drew the attention of researchers. Inside this textbook, readers will find comprehensive perspectives on the association between redox homeostasis and the aging process both at the molecular and clinical levels. Due to the inherent relationship between impaired metabolic activities and oxidative stress, the temporal interaction between intermediary metabolism and disturbed redox status can lead to greater susceptibility to aging-induced diseases and disorders, such as cardiovascular diseases, hypertension, and diabetes. This knowledge could be a key to continued research toward improving medication regimens such as in cancer and cardiovascular therapies, and procedural outcomes for patients. This book brings together current research evidence and knowledge on redox signaling and biomarkers in aging in chapters written by leading global experts in this rapidly evolving field. We hope that this textbook is of interest to a wide group of researchers, advanced students, scientifically curious non-specialist readers and clinicians alike.
