Role Of Oxidative Stress In Chronic Diseases

This book presents recent findings on the role of oxidative stress in chronic diseases. Understanding the mechanisms behind it enables readers to comprehend the rationale which underlies intervention in such conditions. The book places special emphasis on genetic polymorphism—an important issue related to this field of study. It covers the role of oxidative stress in transmissible disorders as well as non-transmissible chronic conditions with chapters on metabolic diseases, autoimmune and neurodegenerative diseases, and cancer and cachexia. Each chapter covers a different disorder and the efficacy of interventional procedures.

This book illustrates the importance and significance of oxidative stress in the pathophysiology of various human diseases. The book initially introduces the phenomenon of oxidative stress, basic chemical characteristics of the species involved and summarizes the cellular oxidant and anti-oxidant system and the cellular effects and metabolism of the oxidative stress. In addition, it reviews the current understanding of the potential impact of oxidative stress on telomere shortening, aging, and age-related diseases. It also examines the role of oxidative stress in chronic diseases, including cancer, diabetes, cardiovascular diseases, and neurodegenerative disorders. Further, the book presents novel technologies for the detection of oxidative stress biomarkers using nanostructure biosensors, as well as in vitro and in vivo models to monitor oxidative stress. Lastly, the book addresses the drug delivery carriers that can help in combating oxidative stress.

Atherosclerosis, the underlying cause of heart attacks, strokes and peripheral vascular disease, is one of the major killers in the world. By 2020 WHO statistics indicate that it will be the most common cause of morbidity and mortality in both the industrialised world and the underdeveloped world. The disease develops slowly over many years in the innermost layer of large and medium-sized arteries (Fig. 1) (Scott, 1995; Ross, 1999; Naumova and Scott, 2000; Glass and Witztum, 2001; Libby, 2001). It does not usually become manifest before the fourth of fifth decade, but then often strikes with devas tating suddenness. Fifty per cent of individuals still die (25 per cent immedi ately) from their first heart attack; and morbidity from coronary heart disease and stroke is very significant. The disease has a profound impact on health care services and on industrial economies. The lesions of atherosclerosis Autopsy studies show that in humans atherosclerosis begins in the first and second decade of life. A similar disease can be produced in experimental animals, where diet and genetics can be manipulated to produce identical lesions. The earliest lesions are fatty streaks. These consist of an accumulation of lipid-engorged macrophages (foam cells) and T and B lymphocytes in the arterial intima. With time, the fatty streaks progress to intermediate lesions, composed of foam cells and smooth muscle cells.

This work responds to the need to find, in a sole document, the affect of oxidative stress at different levels, as well as treatment with antioxidants to revert and diminish the damage. Oxidative Stress and Chronic Degenerative Diseases - a Role for Antioxidants is written for health professionals by researchers at diverse educative institutions (Mexico, Brazil, USA, Spain, Australia, and Slovenia). I would like to underscore that of the 19 chapters, 14 are by Mexican researchers, which demonstrates the commitment of Mexican institutions to academic life and to the prevention and treatment of chronic degenerative diseases.

Oxidative stress is an underlying factor in health and disease. Reactive oxygen species are produced as a result of normal cellular metabolism. The subsequent altered redox state between the formation and the neutralization of pro-oxidants results in their increased levels and therefore leads to cellular damage. Different research disciplines have increased our knowledge of the importance of this cell redox status and the recognition of oxidative stress as a process with implications for many pathophysiological states. Genetic and environmental factors, nutrition and lifestyle may indicate a pro-oxidative and pro-inflammatory state, linked to alterations in cellular structure and function. Oxidative stress emerges as a common, unifying factor in several conditions including diabetes and cardiovascular diseases. This eBook aims to provide novel data regarding the role played by oxidative stress and inflammation in the development of chronic diseases and the different classes of therapeutics from the bench to the clinic, stressing the awareness of these concepts for the treatment of disease. In addition, articles addressing an overview of the role of oxidative stress in vascular diseases reviewing some current concepts indicating that oxidative stress and inflammation are key mechanisms linking vascular diseases and current state-of-the-art approaches to monitor, prevent and inhibit oxidative stress will be highlighted. There is a close relation between oxidative stress, inflammation and cardiovascular diseases. Despite the great amount of investigation carried out in the field, there are still uncertainties about the mechanisms by which free radicals can modify tissues such as perivascular adipose tissue that ultimately will reflect on vascular function. This eBook will focus on articles that can explore and identify these mechanisms. Concurrent with this understanding of oxidative stress milieu, it is necessary to recognize the need for new pharmacological tools effective in restoring oxidative balance. The abundance of new information and the paradigm shift in our understanding of how antioxidants and other redox-active drugs work in a wide variety of vascular diseases will be specifically highlighted. This eBook will provide a comprehensive, up-to-date source of information on the design and mechanistic, pharmacological, and medicinal aspects of redox-active therapeutics. Finally, a unique feature of the eBook is to provide a way to foster an enthralling discussion revisiting old paradigms and finding new solutions for the treatment of vascular diseases. The topic will include original research articles, hypotheses, perspectives and (mini)reviews from experts in the field. The next decade shows promise for the translation of this body of knowledge to novel human therapeutics and this eBook will enable to increment our knowledge in this field.

Oxidative stress is the result of an imbalance in pro-oxidant/antioxidant homeostasis that leads to the generation of toxic reactive oxygen species. Brain cells are continuously exposed to reactive oxygen species generated by oxidative metabolism, and in certain pathological conditions defense mechanisms against oxygen radicals may be weakened and/or overwhelmed. DNA is a potential target for oxidative damage, and genomic damage can contribute to neuropathogenesis. It is important therefore to identify tools for the quantitative analysis of DNA damage in models on neurological disorders. This book presents detailed information on various neurodegenerative disorders and their connection with oxidative stress. This information will provide clinicians with directions to treat these disorders with appropriate therapy and is also of vital importance for the drug industries for the design of new drugs for treatment of degenerative disorders. * Contains the latest information on the subject of neurodegenerative disorders * Reflects on various factors involved in degeneration and gives suggestions for how to tackle these problems

Novel Therapeutic Approaches Targeting Oxidative Stress investigates the role of oxidative stress in disease and explores the latest methods and approaches to targeting oxidative stress for treatment and diagnosis. The book begins with an introduction to oxidative stress and its significance. Subsequent sections cover biochemical methods for detecting free radicals and novel therapeutic approaches for targeting oxidative stress in a number of different diseases. This includes age-related illnesses, neuropsychiatric disorders such as schizophrenia and bipolar disorder, and neurodegenerative diseases like Alzheimer’s and Parkinson’s disease. Novel approaches for targeting oxidative stress in cancer and cardiovascular diseases are also explored. The book then moves on to discuss advances in drug delivery systems and detecting oxidative stress biomarkers using biosensors. It concludes with case studies that illustrate the targeting of oxidative stress and future perspectives.
