Download or read book Epigenetics of Aging written by Trygve O. Tollefsbol and published by Springer Science & Business Media. This book was released on 2009-11-11 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Aging in Cell and Tissue Culture written by E. Holeckova and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: The annual meeting of the European Tissue Culture ., Society was held at the Castle of Zinkovy in Czechoslovakia from May 7-10,1969. Included as part of this meeting was a symposium on "Aging in Cell and Tissue Culture." This volume contains the papers presented at that symposium. The use of cell and tissue culture techniques to study the mechanism of aging is not new. For example, it has long been known that age-associated changes which occur in plasma can inhibit cell proliferation in vitro; also that the time lapse prior to cell migration from ex planted tissue fragments increases with increasing age. These are both examples of the expression in vitro of aging in vivo. More recently, attention has been focused on the occurrence of senescence in vitro. These investi gations have included studies of alterations in non dividing cell cultures, and to a somewhat greater extent, of age-related changes in the proliferative capacity of cells in vitro. For example, cells derived from human fetal lung retain many properties of normal cells including a stable normal diploid karyotype and these cultures have been shown to have a limited life-span in vitro. In addi tion, cultures derived from human adult lung show the same normal characteristics and appear to have a shorter life span than cells derived from fetal lung.

Download or read book The Evolution of Senescence in the Tree of Life written by Richard P. Shefferson and published by Cambridge University Press. This book was released on 2017-02-23 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: The existing theories on the evolution of senescence assume that senescence is inevitable in all organisms. However, recent studies have shown that this is not necessarily true. A better understanding of senescence and its underlying mechanisms could have far-reaching consequences for conservation and eco-evolutionary research. This book is the first to offer interdisciplinary perspectives on the evolution of senescence in many species, setting the stage for further developments. It brings together new insights from a wide range of scientific fields and cutting-edge research done on a multitude of different animals (including humans), plants and microbes, giving the reader a complete overview of recent developments and of the controversies currently surrounding the topic. Written by specialists from a variety of disciplines, this book is a valuable source of information for students and researchers interested in ageing and life history traits and populations.

Download or read book Geriatric Oncology written by Martine Extermann and published by Springer. This book was released on 2020-01-30 with total page 1150 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is intended as a comprehensive resource for clinicians and researchers seeking in-depth information on geriatric oncology. The coverage encompasses epidemiology, the biology and (patho)physiology of aging and cancer, geriatric assessment and management, hematologic malignancies, solid tumors, issues in patient care, and research methods. Since cancer is a disease of aging and people are living longer, most cancer patients are now aged 70 and older. Yet the more we age, the more diverse we become in terms of our health, biologic fitness, and cancer behavior. Typically, however, general oncology clinical trials address only a selected healthier and younger population of patients. Geriatric oncology is the area of oncology that addresses these issues but while a wealth of knowledge has been accumulated, information is often difficult to retrieve or insufficiently detailed. The SpringerReference program, in which this book is published, offers an ideal format for overcoming these limitations since it combines thorough coverage with access to living editions constantly updated chapter by chapter via a dynamic peer-review process, ensuring that information remains current and pertinent.

Download or read book How and why We Age written by Leonard Hayflick and published by . This book was released on 1996 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "How long can humans live? Is immortality possible? Just what is the aging process? The aging and inevitable death of the human body have inspired more myths and outrageous quackery than anything else subject to scientific inquiry. . . . Now comes a most fascinating book, insightful and scholarly, to provide what answers have emerged so far." --San Francisco Chronicle Here, at last, preeminent cell biologist Leonard Hayflick presents the truth about human aging. Based on more than thirty years of pioneering research in the field, How and Why We Age explores not only how our major biological systems change as we grow older, but also examines the intangible alterations in our modes of thinking and feeling, our moods and sexual desires, our personality traits and our memories. With the immediacy of the latest scientific discoveries, Dr. Hayflick explains how aging affects every part of the body, and dispels many of the most persistent aging myths, to show that: * Hearts do not naturally get weaker with age. * Regular exercise and a low-fat diet won't slow aging. * Curing cancer would only add two years to the average sixty-five-year-old American life. Curing heart disease, however would add fourteen years. * Only five percent of people over the age of sixty-five are in nursing homes * No human has lived--or probably can live--past 120 years. Gracefully written, clearly organized, and packed with essential facts and statistics, How and Why We Age is a landmark study of the aging process for readers of all ages. "Written in clear, nontechnical language, it is an excellent introduction to the scientific and demographic literature on this multifacetedsubject." --Nature

Download or read book The Future of Human Healthspan written by The National Academies and published by National Academies Press. This book was released on 2008-04-24 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: An individual's healthspan can be defined as the length of time an individual is able to maintain good health. In 2007, over one hundred experts and researchers from public and private institutions across the nation convened to find new ways of addressing the human healthspan and the elusive nature of aging. Experts in public health, bioengineering, neuroscience and gerontology discussed how stress and lifestyle influence the decline of health at older ages. Other discussions focused on the integration of technology in the quality of life, gerontology, regenerative medicine and life expectancy with regard to social and behavioral traits. Still, other groups explored topics such as the cellular and molecular mechanisms of biological aging, the effects of exercise on the human healthspan, and changes in social context to enhance functional status of the elderly. Most importantly, experts agreed that it was imperative to ensure that the elderly have access to medical services by establishing relationships with health care and insurance providers.

Download or read book Between Zeus and the Salmon written by Caleb E. Finch and published by . This book was released on 1997-10-29 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Demographers and public health specialists have been surprised by the rapid increases in life expectancy, especially at the oldest ages, that have occurred since the early 1960s. Some scientists are calling into question the idea of a fixed upper limit for the human life span. There is new evidence about the genetic bases for both humans and other species. There are also new theories and models of the role of mutations accumulating over the life span and the possible evolutionary advantages of survival after the reproductive years. This volume deals with such diverse topics as the role of the elderly in other species and among human societies past and present, the contribution of evolutionary theory to our understanding of human longevity and intergenerational transfers, mathematical models for survival, and the potential for collecting genetic material in household surveys. It will be particularly valuable for promoting communication between the social and life sciences.
