Download or read book Model Systems in Aging written by Thomas Nyström and published by Springer Science & Business Media. This book was released on 2004 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

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 New Directions in the Sociology of Aging written by Panel on New Directions in Social Demography, Social Epidemiology, and the Sociology of Aging and published by National Academies Press. This book was released on 2014-01-09 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aging of the population of the United States is occurring at a time of major economic and social changes. These economic changes include consideration of increases in the age of eligibility for Social Security and Medicare and possible changes in benefit levels. Furthermore, changes in the social context in which older individuals and families function may well affect the nature of key social relationships and institutions that define the environment for older persons. Sociology offers a knowledge base, a number of useful analytic approaches and tools, and unique theoretical perspectives that can facilitate understanding of these demographic, economic, and social changes and, to the extent possible, their causes, consequences and implications. The Future of the Sociology of Aging: An Agenda for Action evaluates the recent contributions of social demography, social epidemiology and sociology to the study of aging and identifies promising new research directions in these sub-fields. Included in this study are nine papers prepared by experts in sociology, demography, social genomics, public health, and other fields, that highlight the broad array of tools and perspectives that can provide the basis for further advancing the understanding of aging processes in ways that can inform policy. This report discusses the role of sociology in what is a wide-ranging and diverse field of study; a proposed three-dimensional conceptual model for studying social processes in aging over the life cycle; a review of existing databases, data needs and opportunities, primarily in the area of measurement of interhousehold and intergenerational transmission of resources, biomarkers and biosocial interactions; and a summary of roadblocks and bridges to transdisciplinary research that will affect the future directions of the field of sociology of aging.

Download or read book Stem Cells and Aging written by Surajit Pathak and published by Academic Press. This book was released on 2021-03-17 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stem Cells and Aging covers what is known about the effect of time and age on the basic units of life, which are the corresponding tissue-specific or adult stem cells. Even though the concept of stem cells was introduced nearly a century ago by Alexander Maximow, modern stem-cell research began in 1963 when James Till, Ernest McCullough and Lou Siminovitch established assays to detect hematopoietic stem cells. In fact, given the importance of the aging-associated diseases, scientists have developed a keen interest in understanding the aging process as they attempt to define the role of dysfunctional stem cells in the aging process. With an aging population worldwide, understanding these age-related stem cell changes at a basic biology level and at the level of their influences for regenerative medicine is of interest and importance. There is increasing evidence that the aging process can have much adverse effects on stem cells. In the modern era, one of the emerging fields in treating human diseases is stem cell research, as stem cells have the remarkable potential to treat a wide range of diseases. Nevertheless, understanding the molecular mechanism involved in aging and deterioration of stem cell function is crucial in developing effective new therapies for aging. Serves as an ideal reference to guide investigators toward valuable answers to the problems of our aging population Addresses the effect of time and age on human stem cells Includes chapters from contributors exploring the biology of stem cell aging around the globe
Download or read book Age Friendly Health Systems written by Terry Fulmer and published by Institute for Healthcare Improvement (Ihi). This book was released on 2022-02 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: According to the US Census Bureau, the US population aged 65+ years is expected to nearly double over the next 30 years, from 43.1 million in 2012 to an estimated 83.7 million in 2050. These demographic advances, however extraordinary, have left our health systems behind as they struggle to reliably provide evidence-based practice to every older adult at every care interaction. Age-Friendly Health Systems is an initiative of The John A. Hartford Foundation and the Institute for Healthcare Improvement (IHI), in partnership with the American Hospital Association (AHA) and the Catholic Health Association of the United States (CHA), designed Age-Friendly Health Systems to meet this challenge head on. Age-Friendly Health Systems aim to: Follow an essential set of evidence-based practices; Cause no harm; and Align with What Matters to the older adult and their family caregivers.
