Biomarkers For Antioxidant Defense And Oxidative Damage

Biomarkers for Antioxidant Defense and Oxidative Damage: Principles and Practical Applications critically evaluates the basic concepts and methodologies of conventional biomarkers as well as current state-of-the-art assays for measuring antioxidant activity/oxidative stress and their practical applications. . Biomarkers for Antioxidant Defense and Oxidative Damage: Principles and Practical Applications will be of a great interest to scientists who are involved in basic research on oxidation, applied scientists evaluating the effects of nutraceuticals or pharmaceutical compounds on antioxidant activity/oxidative stress, and physicians who want to understand the degree of oxidative damage in patients with certain chronic diseases. Discovering sensitive and specific biomarkers for systemic oxidative damage is essential to understand the role of oxidative stress in human disease. Once these roles are clearly understood, we are able to identify novel drug and nutraceutical targets. This volume goes beyond conventional analytical methods of measuring overall antioxidant activity and provides insight to the discovery of biomarkers that reveal information on specific areas of oxidative stress. Contributed by an international list of experts, Biomarkers for Antioxidant Defense and Oxidative Damage: Principles and Practical Applications describes both conventional biomarkers and recent developments in this area. Special Features: Discusses conventional biomarkers as well as recent advances for measuring antioxidants and oxidative stress Biomarkers for lipid peroxidation: isoprostane, hydroxyloctadecaenoic acid, oxysterols, and reactive carbonyl species from lipid peroxidation Biomarkers for protein oxidation: carbonylation, tyrosine oxidation, ubiquitin-conjugation Biomarkers for DNA oxidative damage: comet assay, hydroxylated nucleotides, and exocylcic DNA adducts Recently developed biomarkers from cutting-edge technology

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.

This book discusses the importance of oxidative stress, related biomarkers, and its diagnostic methods including bio-analytical and advanced detection systems. Oxidative stress is associated with diminished capacity of a biological system to overcome the overproduction of reactive oxygen species. Since oxidative stress has been suggested as a causative factor in many diseases, its prevention is vital, and there is an urgent need for oxidative stress monitoring using in vitro and in vivo models. Interdisciplinary approaches have lead to the development of various oxidative stress monitoring models for real-world clinical and biomedical applications. The development of such methods requires a broad understanding of biology, chemistry, molecular biology, immunology and microbiology. As such, the book is a valuable resource for students, researchers and clinicians interested in the fundamental as well as applied aspects of oxidative stress associated diseases.

The first protocols book, Free Radical and Antioxidant Protocols (1) was published in late 1998. Sections were divided into three parts, covering selected biochemical techniques for measuring oxidative stress, antioxidant (AOX) activity, and combined applications. In choosing the 40 methods to be included in that book, I realized there were considerably more of equal value than that which we could have presented in a single volume. To produce a comprehensive resource, this book and a third are being compiled to expand coverage of the field. A summary of papers (2) published on this important subject emphasizes the continuing rapid growth in oxidative stress investigations relating to our understanding of biochemical reactions, their relevance to pathophysiological mechanisms, how disease may arise, and how therapeutic intervention may be achieved(3). Although there is some overlap between the categories, the ana- sis shown below illustrates where current studies are concentrated and are almost evenly distributed between free radicals and AOX. Over the last 4 yr, there has been a 55% increase in the number of papers published in the area.

Examines oxidative stress in a variety of models, at rest and after exercise. This book presents key concepts of oxidative stress, exercise and aging; explains oxidative stress in different types of exercises; and includes knowledge of the underlying mechanisms influencing health and disease processes associated with oxidative stress.

This book focuses on the numerous applications of oxidative stress theory in effects of environmental factors on biological systems. The topics reviewed cover induction of oxidative stress by physical, chemical, and biological factors in humans, animals, plants and fungi. The physical factors include temperature, light and exercise. Chemical induction is related to metal ions and pesticides, whereas the biological one highlights host-pathogen interaction and stress effects on secretory systems. Antioxidants, represented by a large range of individual compounds and their mixtures of natural origin and those chemically synthesized to prevent or fix negative effects of reactive species are also described in the book. This volume will be a useful source of information on induction and effects of oxidative stress on living organisms for graduate and postgraduate students, researchers, physicians, and environmentalists.

In the past decade there has been a major sea change in the way disease is diagnosed and investigated due to the advent of high throughput technologies, such as microarrays, lab on a chip, proteomics, genomics, lipomics, metabolomics etc. These advances have enabled the discovery of new and novel markers of disease relating to autoimmune disorders, cancers, endocrine diseases, genetic disorders, sensory damage, intestinal diseases etc. In many instances these developments have gone hand in hand with the discovery of biomarkers elucidated via traditional or conventional methods, such as histopathology or clinical biochemistry. Together with microprocessor-based data analysis, advanced statistics and bioinformatics these markers have been used to identify individuals with active disease or pathology as well as those who are refractory or have distinguishing pathologies. New analytical methods that have been used to identify markers of disease and is suggested that there may be as many as 40 different platforms. Unfortunately techniques and methods have not been readily transferable to other disease states and sometimes diagnosis still relies on single analytes rather than a cohort of markers. There is thus a demand for a comprehensive and focused evidenced-based text and scientific literature that addresses these issues. Hence the formulation of Biomarkers in Disease. The series covers a wide number of areas including for example, nutrition, cancer, endocrinology, cardiology, addictions, immunology, birth defects, genetics and so on. The chapters are written by national or international experts and specialists.
