Oxidative Stress And Antioxidants

Oxidative Stress and Antioxidant Protection: The Science of Free Radical Biology and Disease Oxidative Stress and Antioxidant Protection begins with a historical perspective of pioneers in oxidative stress with an introductory section that explains the basic principles related to oxidative stress in biochemistry and molecular biology, demonstrating both pathways and biomarkers. This section also covers diagnostic imaging and differential diagnostics. The following section covers psychological, physiologic, pharmacologic and pathologic correlates. This section addresses inheritance, gender, nutrition, obesity, family history, behavior modification, natural herbal-botanical products, and supplementation in the treatment of disease. Clinical trials are also summarized for major medical disorders and efficacy of treatment, with particular focus on inflammation, immune response, recycling, disease progression, outcomes and interventions. Each of the chapters describes what biomarker(s) and physiological functions may be relevant to a concept of specific disease and potential alternative therapy. The chapters cover medical terminology, developmental change, effects of aging, senescence, lifespan, and wound healing, and also illustrates cross-over exposure to other fields. The final chapter covers how and when to interpret appropriate data used in entry level biostatistics and epidemiology. Authored and edited by leaders in the field, Oxidative Stress and Antioxidant Protection will be an invaluable resource for students and researchers studying cell biology, molecular biology, and biochemistry, as well professionals in various health science fields.

Oxidative Stress is intended as an in-depth account of knowledge and problems in the field of oxygen-related damage in biological systems. The topics range from an assessment of molecular events in in vitro model systems to complex problems in clinical medicine. Organized into two parts with a total of 18 chapters, this book begins with an introduction to oxidative stress, elucidating specific topics on reactive oxygen species, detoxification system, and nature of oxidative damage. The first part focuses on models used with cells and tissues in the study of oxidative stress, whereas the second part describes the processes elicited by oxidative stress.

Oxidative stress is a relatively new concept that has been widely implicated in biomedical sciences during the last 20 years. It significantly participates in the pathophysiology of highly prevalent diseases such as diabetes, hypertension, preeclampsia, atherosclerosis, acute renal failure, Alzheimer and Parkinson diseases, among others. The metabolism of oxygen by cells generates potentially deleterious reactive oxygen species (ROS). Under normal conditions the rate and magnitude of oxidant formation is balanced by the rate of oxidant elimination However, an imbalance between pro-oxidants and antioxidants results in oxidative stress. Increased ROS levels in the cell have a substantial impact either leading to defective cellular function, ageing, or disease. Therefore, a better understanding of the roles of ROS-mediated signalling in normal cellular function as well as in disease is necessary for developing therapeutic tools for oxidative stress-related pathologies. The potential beneficial role of antioxidants is discussed in the light of experimental studies, as well as clinical trials aimed to determine the outcome of patients. "Oxidative Stress and Antioxidants: Their Role in Human Disease" is a practical guide for pathophysiology of oxidative stress and the latest therapeutic advances to modulate the antioxidant defence. This includes evidence from clinical trials, regarding the use of antioxidants and preconditioning, to protect the organism against ROS.

The use of antioxidants in sports is controversial due to existing evidence that they both support and hinder athletic performance. Antioxidants in Sport Nutrition covers antioxidant use in the athlete ́s basic nutrition and discusses the controversies surrounding the usefulness of antioxidant supplementation. The book also stresses how antioxidants may affect immunity, health, and exercise performance. The book contains scientifically based chapters explaining the basic mechanisms of exercise-induced oxidative damage. Also covered are methodological approaches to assess the effectiveness of antioxidant treatment. Biomarkers are discussed as a method to estimate the bioefficacy of dietary/supplemental antioxidants in sports. This book is useful for sport nutrition scientists, physicians, exercise physiologists, product developers, sport practitioners, coaches, top athletes, and recreational athletes. In it, they will find objective information and practical guidance.

Cancer: Oxidative Stress and Dietary Antioxidants bridges the trans-disciplinary divide and covers in a single volume the science of oxidative stress in cancer and then the potentially therapeutic usage of natural antioxidants in the diet or food matrix. The processes within the science of oxidative stress are described in concert with other processes such as apoptosis, cell signaling, and receptor mediated responses. This approach recognizes that diseases are often multifactorial and that oxidative stress is a single component of this. Oncologists, cancer researchers, and nutritionists are separated by divergent skills and professional disciplines that need to be bridged in order to advance preventative as well as treatment strategies. While oncologists and cancer researchers may study the underlying pathogenesis of cancer, they are less likely to be conversant in the science of nutrition and dietetics. On the other hand, nutritionists and dietitians are less conversant with the detailed clinical background and science of oncology. This book addresses this gap and brings each of these disciplines to bear on the processes inherent in the oxidative stress of cancer. Nutritionists can apply information related to mitochondrial oxidative stress in one disease to diet-related strategies in another unrelated disease Dietitians can prescribe new foods or diets containing anti-oxidants for conditions resistant to conventional pharmacological treatments Dietitians, after learning about the basic biology of oxidative stress, will be able to suggest new treatments to their multidisciplinary teams Nutritionists and dietitians will gain an understanding of cell signaling, and be able to suggest new preventative or therapeutic strategies with anti-oxidant rich foods

The global popularity of herbal supplements and the promise they hold in treating various disease states has caused an unprecedented interest in understanding the molecular basis of the biological activity of traditional remedies. Herbal Medicine: Biomolecular and Clinical Aspects focuses on presenting current scientific evidence of biomolecular ef

With contributions that review research on this topic throughout the world, Oxidative Damage to Plants covers key areas of discovery, from the generation of reactive oxygen species (ROSs), their mechanisms, quenching of these ROSs through enzymatic and non-enzymatic antioxidants, and detailed aspects of such antioxidants as SOD and CAT. Environmental stress is responsible for the generation of oxidative stress, which causes oxidative damage to biomolecules and hence reduces crop yield. To cope up with these problems, scientists have to fully understand the generation of reactive oxygen species, its impact on plants and how plants will be able to withstand these stresses. Provides invaluable information about the role of antioxidants in alleviating oxidative stress Examines both the negative effects (senescence, impaired photosynthesis and necrosis) and positive effects (crucial role that superoxide plays against invading microbes) of ROS on plants Features contributors from a variety of regions globally

Oxidative Stress and Biomaterials provides readers with the latest information on biomaterials and the oxidative stress that can pose an especially troubling challenge to their biocompatibility, especially given the fact that, at the cellular level, the tissue environment is a harsh landscape of precipitating proteins, infiltrating leukocytes, released oxidants, and fluctuations of pH which, even with the slightest shift in stasis, can induce a perpetual state of chronic inflammation. No material is 100% non-inflammatory, non-toxic, non-teratogenic, non-carcinogenic, non-thrombogenic, and non-immunogenic in all biological settings and situations. In this embattled terrain, the most we can hope for from the biomaterials we design is a type of “meso-compatibility, a material which can remain functional and benign for as long as required without succumbing to this cellular onslaught and inducing a local inflammatory reaction. Explores the challenges of designing and using biomaterials in order to minimize oxidative stress, reducing patterns of chronic inflammation and cell death Brings together the two fields of biomaterials and the biology of oxidative stress Provides approaches for the design of biomaterials with improved biocompatibility
