The Molecular Genetics of Aging
The molecular genetics of aging or life-span determination is an expanding field. One reason is because many people would consider it desirable if hu man life span could be extended. Indeed, it is difficult not to be fascinated by tales of the life and death of people who have succeeded in living a very long life. Because of this, we have placed at the head of this book the chapter by Perls et al. on Centenerians and the Genetics of Longevity. Perls and his coauthors convincingly argue that, while the average life expectancy might be mostly determined by environmental factors because the average person has an average genotype, extremely long life spans are genetically determined. Of course, ...
Model Systems in Aging
Aging is the progressive decline in biological functions over time. This decline targets macromolecules, cells, tissues and, as a consequence, whole organisms. Despite considerable progress in the development of testable hypothesis concerning aging in an evolutionary context, a unifying theory of the molecular/physiological mechanistic causes of aging has not been reached. In fact, is it not clear to what extent aging is a programmed or stochastic process. This book takes the reader from unicellular bacterial deterioration via senescence in fungi and worms to aging in rodents and humans, allowing a comparative view on similarities and differences in different genetic model systems. The different model systems are scrutinized in the light of contemporary aging hypothesis, such as the free radical and genomic instability theories.
Free Radicals and Aging
Among the various theories proposed to account for the process of aging, the free radical theory is of practical interest since it includes the possibility of retarding this process by administrating natural or synthetic antioxidants and free radical scavengers. The book "Free Radicals and Aging" summarizes knowledge accumulated during recent years in 42 reviews written by experts in the field. Aspects of free radical involvement in the intrinsic aging process and in age-related diseases, as well as the importance of the pro-antioxidant balance throughout life are discussed. Epidemiological studies from several European countries are reported showing correlations between low plasma levels of...
Understanding the Process of Aging
This innovative reference explores a wide selection of topics associated with aging, providing a solid understanding of the significance and molecular basis of the aging process and charting the course of future research in the area. Stresses the interplay of mitochondria, mitochondrial DNA, oxidants, and antioxidants! Featuring the research of over 55 experts in the area, Understanding the Process of Aging covers the functions of nitric oxide and peroxynitrite in mitochondria integrates several views on the role of mitochondria in the development of apoptosis gives a quantitative analysis of mutations of mitochondrial DNA during human aging highlights mitochondrial free radical production i...
Cancer and Aging Handbook
A state-of-the-art, multidisciplinary approach to cancer and aging With the majority of cancers occurring in individuals over the age of 65 against a backdrop of an expanding aging population, there is an urgent need to integrate the areas of clinical oncology and geriatric care. This timely work tackles these issues head-on, presenting a truly multidisciplinary and international perspective on cancer and aging from world-renowned experts in geriatrics, oncology, behavioral science, psychology, gerontology, and public health. Unlike other books on geriatric oncology that focus mainly on treatment, Cancer and Aging Handbook: Research and Practice examines all phases of the cancer care continu...
Critical Reviews of Oxidative Stress and Aging
This two-volume reference examines the translational research field of oxidative stress and ageing. It focuses on understanding the molecular basis of oxidative stress and its associated age-related diseases, with the goal of developing new methods for treating the human ageing processes.
Free Radicals: from Basic Science to Medicine
Free radical-mediated reactions have been well known in chemistry and physical chemistry for many years. Applying this knowledge to living organisms, biochemists have shown that reactive free radicals are formed at many intracellular sites during normal metabolism, and they have started to suggest possible roles in various pathological processes and conditions, for example in radiation damage, in the metabolism of xenobiotics, in carcinogenesis and in metabolic disorders. At present, a large and relevant mass of experimental evidence supports the view that reactive free radicals are involved in the pathogenesis of several diseases and syndromes. This literature has captured the attention and...
Annual Review of Gerontology and Geriatrics, Volume 10, 1990
This volume presents a clear, concise overview of the current state of knowledge about the biology of aging ñ serving as both an invaluable graduate-level text and a key reference for practicing professionals. Over a dozen distinguished contributors probe the latest developments in our knowledge of why people age and how the process works. These authoritative chapters are not just written for biologists ñ but for gerontologists in general. Marks the tenth anniversary of the Annual Review of Gerontology and Geriatrics.
Antioxidant and Redox Regulation of Genes
This volume addresses oxidant-reduction or redox and antioxidant sensitive molecular mechanisms and how they are implicated in different disease processes. Possible strategies to pharmacologically and/or nutritionally manipulate such redox-sensitive molecular responses are emphasized. - Reactive species as intracellular messengers - Redox regulation of cellular responses - Clinical implications of redox signaling and antioxidant therapy
