Aging has long since been ascribed to the gradual accumulation of DNA mutations in the genome of somatic cells. However, it is only recently that the necessary sophisticated technology has been developed to begin testing this theory and its consequences. Vijg critically reviews the concept of genomic instability as a possible universal cause of aging in the context of a new, holistic understanding of genome functioning in complex organisms resulting from recent advances in functional genomics and systems biology. It provides an up-to-date synthesis of current research, as well as a look ahead to the design of strategies to retard or reverse the deleterious effects of aging. This is particularly important in a time when we are urgently trying to unravel the genetic component of aging-related diseases. Moreover, there is a growing public recognition of the imperative of understanding more about the underlying biology of aging, driven by continuing demographic change.

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.

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

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.

Recognition that aging is not the accumulation of disease, but rather comprises fundamental biological processes that are amenable to experimental study, is the basis for the recent growth of experimental biogerontology. As increasingly sophisticated studies provide greater understanding of what occurs in the aging brain and how these changes occur

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.

The strongest point of this book titled “Biochemistry of Oxidative Stress: Physiopathology and Clinical Aspects”, is that the academic and scientific background of the authors/editors guarantee the authorship of a book comprising all aspects of oxidative stress, ranging from very molecular aspects, to clinical application, including the antioxidant therapy. Of particular importance is the fact that the aforementioned aspects are described in the book in a general section and in three different and important pathologies, such as cardiovascular diseases, neurodegenerative diseases, and cancer. The importance of these pathologies lays in the fact that, taken separately or together, they represent by far the leading cause of death in the world. Finally, all the chapters have been written by highly recognized authorities in the field of their investigations. At least to our knowledge, this is the first book with this characteristics in the field of oxidative stress.

One of the major biomedical triumphs of the post-World War II era was the defmitive demonstration that hypercholesterolemia is a key causative factor in atherosclerosis; that hypercholesterolemia can be effectively treated; and that treatment significantly reduces not only coronary disease mortality but also all cause mortality. Treatment to lower plasma levels of cholesterol - primarily low density lipoprotein (LDL) cholesterol - is now accepted as best medical practice and both physicians and patients are being educated to take aggressive measures to lower LDL. We can confidently look forward to important decreases in the toll of coronary artery disease over the coming decades. However, there is still uncertainty as to the exact mechanisms by which elevated plasma cholesterol and LDL levels initiate and favor the progression of lesions. There is general consensus that one of the earliest responses to hypercholesterolemia is the adhesion of monocytes to aortic endothelial cells followed by their penetration into the subendothelial space, where they differentiate into macrophages. These cells, and also medial smooth muscle cells that have migrated into the subendothelial space, then become loaded with mUltiple, large droplets of cholesterol esters . . . the hallmark of the earliest visible atherosclerotic lesion, the so-called fatty streak. This lesion is the precursor of the more advanced lesions, both in animal models and in humans. Thus the centrality of hypercholesterolemia cannot be overstated. Still, the atherogenic process is complex and evolves over a long period of time.
