Book Description
This work covers a number of relevant aspects of the molecular and cellular biology of ageing, a timely general topic highlighted by the United Nations' having declared 1999 the Year of the Elderly. The papers published here represent a wide range of complementary research areas: molecular and cellular aspects; theories of ageing; molecular basis of the loss of homeostatic maintenance mechanisms; lower and higher model organisms including transgenic animal models; the genetics of human longevity; clinical and molecular aspects of age-related diseases; and integrated systems like brain and immune system aging. It is hoped that the additions to knowledge of the molecular mechanisms of ageing provided by this volume may ultimately lead to the prevention of age-related diseases.

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
Molecular Basis of Aging is a collection of papers that discuss the molecular aspects of aging in the light of molecular biology, biochemical gerontology, and genetics. Each chapter of the book contains a different study about the topic, which includes the effects of aging on DNA synthesis; the amplification of extrachromosomal circular copies and mitochondrial DNA during aging; and the altered actions of hormones and neurotransmitters during aging. The book also encompasses the loss of responsiveness to growth factors in cell senescence; the integration of cellular-molecular and neuroendocrine concepts of aging; changes and inactivation of enzymes during aging; and the relationship of aging with free radicals. The text is recommended for molecular biologists, biochemists, and gerontologists who wish to study further the effects of aging on the body on a molecular level.

Book Description
Sleep and Aging provides a unique and timely collection of review articles that cover the gamut of basic and clinical aspects of sleep and the abnormalities in sleep associated with aging and neurological disorders that occur during aging. From the evolutionary basis of sleep and its normal functions in processes such as learning and memory, to considerations of the roles of sleep abnormalities in neurological disorders such as depression, Alzheimer's and Parkinson's diseases, the chapters are written by experts in the field. Several chapters focus on signalling pathways involved in sleep regulation and abnormalities in sleep, including those activated by serotonin and BDNF. Basic and clinical research on insomnia, sleep apnea and other disorders of sleep, are covered thus providing students and scientists at all levels with a valuable source of information to advance their understanding of this important topic in aging, biology and medicine. The circuits in the brain involved in sleep regulation, their neurochemistry, how they are altered in disorders of sleep and current clinical treatments of various sleep disorders are reviewed. The important role of sleep disturbances in neurodegenerative disorders is described and research in this particular area is leading to a better understanding of the relationships between synaptic plasticity, neuronal degeneration and the clinical manifestations of disorders such as Alzheimer's disease, Parkinson's disease and depression. This book is a must for scientists, as well as non-scientists, who are interested in the neurobiology of aging, sleep and neurodegenerative disorders.

Book Description
Background Cancer is a variety of malignancies generally associated with aging. As the overall health technology and health care delivery improved with the advances made in medicine and science in the United States, the life expectancy of the population also increased. The average life expectancy in the U. S. A. has increased from 49 years at the end of 1900 to 75 years today in 1990 (1-3). The population of 65 years and older that constituted 25. 5 million or 11. 3% of the total U. S. population in 1980(4) has now increased to 31. 1 million or 12. 5% of the population according to the 1990(5) census. As cancer diagnosis and treatment have improved, cancer mortality among patients under 55 has been significantly reduced within recent years *1; however, cancer incidence under 55 is still increasing at about 0. 4% per year (as compared to 1. 0% for all ages or 0. 6% for

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
Time, Cells, and Aging, 2nd Edition presents the mechanics of cell function and the relevant implications of the molecular-genetic view to the aging phenomena. This book explores the biology of the aging process. Comprised of 11 chapters, this edition starts with an overview of the causes and mechanisms underlying the gradual deterioration of structure and function characteristics of aging. This text then examines the two aspects of the behavior of man, including the reasoned conscious behavior and the greater dependence on reaction patterns predicted on the successful responses of the past. Other chapters explore the relationship between aging and mortality rate in animals, which is a result of an organism's deceasing ability to function optimally in carrying out his vital functions. The final chapter deals with the implementation of a research plan relevant to understanding the primary mechanisms of the aging process. This book is a valuable resource for gerontologists, biologists, and molecular biologists.
