Book Description
Why do we age? The answer to this question is critical to our ability to prevent and treat highly age-related diseases such as cancer and heart disease that now cause the deaths of most people in the developed world. This short book provides an overview of biological aging theories including history, current status, major scientific controversies, and implications for the future of medicine. Major topics include: human mortality as a function of age, aging mechanisms and processes, the programmed vs. non-programmed aging controversy, empirical evidence on aging, and the feasibility of anti-aging and regenerative medicine. Evolution theory is essential to aging theories. Theorists have been struggling for 150 years to explain how aging, deterioration, and consequent death fit with Darwin’s survival of the fittest concept. This book explains how continuing genetics discoveries have produced changes in the way we think about evolution that in turn lead to new thinking about the nature of aging.

Book Description
Americans are living longer, and the elder population is growing larger. To meet the ongoing need for quality information on elder health, the Encyclopedia of Aging and Public Health combines multiple perspectives to offer readers a more accurate and complete picture of the aging process. The book takes a biopsychosocial approach to the complexities of its subject. In-depth introductory chapters include coverage on a historical and demographic overview of aging in America, a guide to biological changes accompanying aging, an analysis of the diversity of the U.S. elder population, legal issues commonly affecting older adults, and the ethics of using cognitively impaired elders in research. From there, over 425 entries cover the gamut of topics, trends, diseases, and phenomena: -Specific populations, including ethnic minorities, custodial grandparents, and centenarians -Core medical conditions associated with aging, from cardiac and pulmonary diseases to Parkinson’s and Alzheimer’s -Mental and emotional disorders -Drugs/vitamins/alternative medicine -Disorders of the eyes, feet, and skin -Insomnia and sleep disorders; malnutrition and eating disorders -Sexual and gender-related concerns -And a broad array of social and political issues, including access to care, abuse/neglect, veterans’ affairs, and assisted suicide Entries on not-quite-elders’ concerns (e.g., midlife crisis, menopause) are featured as well. And all chapters and entries include references and resource lists. The Encyclopedia has been developed for maximum utility to clinicians, social workers, researchers, and public health professionals working with older adults. Its multidisciplinary coverage and scope of topics make this volume an invaluable reference for academic and public libraries.

Book Description
The field of gerontology has often been criticized for being "data-rich but theory-poor." The editors of this book address this issue by stressing the importance of theory in gerontology. While the previous edition focused on multidisciplinary approaches to aging theory, this new edition provides cross-disciplinary, integrative explanations of aging theory: The contributors of this text have reached beyond traditional disciplinary boundaries to partner with researchers in adjacent fields in studying aging and age-related phenomena. This edition of the Handbook consists of 39 chapters written by 67 internationally recognized experts in the field of aging. It is organized in seven sections, reflecting the major theoretical developments in gerontology over the past 10 years. Special Features: Comprehensive coverage of aging theory, focusing on the biological, psychological, and social aspects of aging A section dedicated to discussing how aging theory informs public policy A concluding chapter summarizing the major themes of aging, and offering predictions about the future of theory development Required reading for graduate students and post doctoral fellows, this textbook represents the current status of theoretical development in the study of aging.

Book Description
This unique book looks at the biology of aging from a fundamentally new perspective, one based on evolutionary theory rather than traditional concepts which emphasize molecular and cellular processes. The basis for this approach lies in the fact that natural selection, as a powerful determining force, tends to decline in importance with age. Many of the characteristics we associate with aging, the author argues, are more the result of this decline than any mechanical imperative contained within organic structures. This theory in turn yields the most fruitful avenues for seeking answers to the problem of aging, and should be recognized as the intellectual core of gerontology and the foundation for future research. The author ably surveys the vast literature on aging, presenting mathematical, experimental, and comparative findings to illustrate and support the central thesis. The result is the first complete synthesis of this vital field. Evolutionary biologists, gerontologists, and all those concerned with the science of aging will find it a stimulating, strongly argued account.

Book Description
In Endocrinology of Aging, a panel of distinguished physicians critically reviews the clinical consequences of the endocrinological changes that occur with aging-in both men and women-and examine the use of hormonal therapy to reduce them. Topics range from bone disease and water balance in all older people, to androgen deficiency in aging males, gynecomastia, and menopause. The authors also discuss Type II diabetes in persons over 65, emphasizing the cognitive benefits of good glycemia control, and the interaction of nutrition and metabolism, focusing on hypocholesterolemia, obesity, the anorexia of aging, trace elements, and vitamins. The aging of the sympathetic nervous system and its impact on hypertension in the elderly is also covered. Timely and authoritative, Endocrinology of Aging offers endocrinologists, geriatricians, and primary care physicians critical insight into the endocrine problems of our rapidly growing elderly population. The valuable information here will greatly augment every physician's ability to enhance function in their aging patients by insightful application of modern treatment regimes and today's powerful new therapeutics.

Book Description
Recent studies have indicated that epigenetic processes may play a major role in both cellular and organismal aging. These epigenetic processes include not only DNA methylation and histone modifications, but also extend to many other epigenetic mediators such as the polycomb group proteins, chromosomal position effects, and noncoding RNA. The topics of this book range from fundamental changes in DNA methylation in aging to the most recent research on intervention into epigenetic modifications to modulate the aging process. The major topics of epigenetics and aging covered in this book are: 1) DNA methylation and histone modifications in aging; 2) Other epigenetic processes and aging; 3) Impact of epigenetics on aging; 4) Epigenetics of age-related diseases; 5) Epigenetic interventions and aging: and 6) Future directions in epigenetic aging research. The most studied of epigenetic processes, DNA methylation, has been associated with cellular aging and aging of organisms for many years. It is now apparent that both global and gene-specific alterations occur not only in DNA methylation during aging, but also in several histone alterations. Many epigenetic alterations can have an impact on aging processes such as stem cell aging, control of telomerase, modifications of telomeres, and epigenetic drift can impact the aging process as evident in the recent studies of aging monozygotic twins. Numerous age-related diseases are affected by epigenetic mechanisms. For example, recent studies have shown that DNA methylation is altered in Alzheimer’s disease and autoimmunity. Other prevalent diseases that have been associated with age-related epigenetic changes include cancer and diabetes. Paternal age and epigenetic changes appear to have an effect on schizophrenia and epigenetic silencing has been associated with several of the progeroid syndromes of premature aging. Moreover, the impact of dietary or drug intervention into epigenetic processes as they affect normal aging or age-related diseases is becoming increasingly feasible.

Book Description
During the last 40 years, the study of the biological basis of aging has progressed tremendously, and it has now become an independent and respectable field of study and research. The essential cause of aging is molecular damage that slowly overwhelms cellular and organismic defense, repair and maintenance systems. In recent years, a wealth of highly sophisticated research has transformed this idea from a credible hypothesis not only to a major theory, but essentially to accepted knowledge. Aging at the Molecular Level examines the key elements in this transformation. Bringing together contributions from an international team of authors, this volume will be of interest to graduates and postgraduates in the fields of medicine and nursing, researchers of different aspects of biogerontology and those in the pharmaceutical, cosmeceutical, nutraceutical and health-care industry.

Book Description
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.
