Download or read book Oxidative Stress in Mitochondria Disorders of Aging written by M. Ebadi and published by . This book was released on 2001 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neurons are particularly vulnerable to age-associated decline in mitochondrial function due to their high energy demand. Thus, several models are proposed implicating mtDNA damage and mutation, and subsequent mitochondrial dysfunction, as an underlying factor in a substantial number of human pathologies including aging, neurodegenerative and neuromuscular diseases, and ischemia-reperfusion injury. Furthermore, the results of clinical, biochemical and molecular biology studies suggest that defective mitochondria contribute to neurodegenerative diseases in humans. For example, Friedreich's ataxia exhibits mitochondrial iron overload, Huntington's disease is characterized by defects in mitochondrial oxidative phosphorylation and aconitase deficiency, Parkinson's disease is associated with a deficiency in mitochondrial complex I activity, and Alzheimer's disease exhibits cytochrome oxidase deficiency. Neurologists, psychiatrists and biochemists will profit most from this special issue.

Download or read book Mitochondrial Dysfunction in Aging and Diseases of Aging written by Richard H. Haas and published by MDPI. This book was released on 2019-10-01 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: This collection of review articles authored by international experts pulls together current information about the role of mitochondria in aging and diseases of aging. Mitochondria are vitally important cellular organelles and undergo their own aging process becoming less efficient in aged animals including humans. These changes have wide-ranging significance contributing to immune dysfunction (autoimmunity and immune deficiency), inflammation, delayed healing, skin and retinal damage, cancer and most of the degenerative diseases of aging. Mitochondrial aging predisposes to drug toxicity in the geriatric population and to many of the features of normal aging. The research detailed in this book summarizes current understanding of the role of mitochondria in the complex molecular changes of aging, moving on to specific diseases of aging. Mitochondrial dysfunction is an important target for development of treatments for aging and disease. The last article details how exercise is a treatment and combats many features of the aging process.

Download or read book Oxidative Stress and Aging written by R.C. Cutler and published by Birkhäuser. This book was released on 2012-12-06 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oxidative stress and aging Over the past several years there has been an extraordinarily rapid growth in our knowledge of free radical chemistry and its possible involvement in both normal essential biology and age related disease and dysfunction. Much of this growth in the traditionally separate sciences of chemistry and molecular gerontology occurred independently, with little interaction or communi cation between the scientists working in these two fields. In view of the growing maturity of the two fields and the potential importance of advancing our knowledge in the area of oxidative stress and aging, we perceived a critical need to organize an international conference the "First Inter national Conference on Oxidative Stress and Aging" in Hawaii in 1994 to bring together the world's leading scientists in the fields of reactive oxygen species and molecular gerontology. The objective of this conference was to provide a unique opportunity for scholars working in these two related and rapidly growing fields to participate in the exchange, integration, and synthesis of new concepts and ideas, to engage in constructive criticism and to initiate new collaborative research projects. The conference focused on the molecular and cellular aspects of aging as related to oxidative stress. It was one of the largest and most comprehensive international conferences held in molecular gerontology. At this conference a call was made for submission of papers to be used in the publication of a book covering the major contributions of the meeting.

Download or read book Decreasing Oxidative Stress and Retarding the Aging Process written by Borut Poljsak and published by Nova Science Publishers. This book was released on 2011-02-08 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ageing is an inevitable biological process that affects most living organisms. The link between metabolic rate and reactive oxygen species production is an important and long-standing question, and a source of much controversy. A by-product of cell respiration in mitochondria is the formation of reactive oxygen species due to electron leakage from the electron transport chain during oxidative phosphorylation. In simple terms, humans are ageing due to oxygen consumption. Damage induced by oxygen appears to be the major contributor to ageing and the degenerative diseases of ageing such as cancer, cardiovascular disease, immune system decline, and brain dysfunction. This book presents the reasons for oxidative stress formation and the answer to why during the course of evolution the process of free radical damage and defense did not become more perfect so as to produce less free radicals.

Download or read book Aging written by L. Robert and published by Karger Medical and Scientific Publishers. This book was released on 2014-05-16 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aging inspired a large number of theories trying to rationalize the aging process common to all living beings. In this publication the most important environmental and intrinsic mechanisms involved in the aging process and in its pathological consequences are reviewed. Furthermore theoretical and experimental evidence of the most important theoretical elements based on Darwinian evolution, cellular aging, role of cell membranes, free radicals and oxidative processes, receptor-mediated reactions, the extracellular matrix and immune functions as well as the most important environmental and intrinsic mechanisms involved in the aging process and in its pathological consequences are discussed. These presentations of theories and related experimental facts give a global overview of up to date concepts of the biology of the aging process and are of essential reading not only for specialists in this field but also for practitioners of scientific, medical, social and experimental sciences.

Download or read book Aging and Age Related Disorders written by Stephen Bondy and published by Springer Science & Business Media. This book was released on 2010-09-02 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: Features that characterize the aging process include the gradual accumulation of cell damage after prolonged exposure to oxidative and inflammatory events over a lifetime. In addition to the accretion of lesions, the intrinsic levels of pro-oxidant and aberrant immune responses are elevated with age. These adverse events are often further enhanced by the chronic and slow progressing diseases that characterize the senescent brain and cardiovascular system. The incidence of some disorders such as Alzheimer's disease and vascular diseases are sufficiently prevalent in the extreme elderly that these disorders can arguably be considered "normal". Aging and Aging-Related Disorders examines the interface between normal and pathological aging, and illustrates how this border can sometimes be diffuse. It explores and illustrates the processes underlying the means by which aging becomes increasingly associated with inappropriate levels of free radical activity and how this can serve as a platform for the progression of age-related diseases. The book provides chapters that examine the interactive relationship between systems in the body that can enhance or sometimes even limit cellular longevity. In addition, specific redox mechanisms in cells are discussed. Another important aspect for aging discussed here is the close relationship between the systems of the body and exposure to environmental influences of oxidative stress that can affect both cellular senescence and a cell’s nuclear DNA. What may be even more interesting to note is that these external stressors are not simply confined to illnesses usually associated with aging, but can be evident in maturing and young individuals. A broad range of internationally recognized experts have contributed to this book. Their aim is to successfully highlight emerging knowledge and therapy for the understanding of the basis and development of aging–related disorders.
