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
Why do we age? Is aging inevitable? Will advances in medical knowledge allow us to extend the human lifespan beyond its present limits? Because growing old has long been the one irreducible reality of human existence, these intriguing questions arise more often in the context of science fiction than science fact. But recent discoveries in the fields of cell biology and molecular genetics are seriously challenging the assumption that human lifespans are beyond our control. With such discoveries in mind, noted cell biologist William R. Clark clearly and skillfully describes how senescence begins at the level of individual cells and how cellular replication may be bound up with aging of the entire organism. He explores the evolutionary origin and function of aging, the cellular connections between aging and cancer, the parallels between cellular senescence and Alzheimer's disease, and the insights gained through studying human genetic disorders--such as Werner's syndrome--that mimic the symptoms of aging. Clark also explains how reduction in caloric intake may actually help increase lifespan, and how the destructive effects of oxidative elements in the body may be limited by the consumption of antioxidants found in fruits and vegetables. In a final chapter, Clark considers the social and economic aspects of living longer, the implications of gene therapy on senescence, and what we might learn about aging from experiments in cloning. This is a highly readable, provocative account of some of the most far-reaching and controversial questions we are likely to ask in the next century.

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
Aging is a major risk factor for chronic diseases, which in turn can provide information about the aging of a biological system. This publication serves as an introduction to systems biology and its application to biological aging. Key pathways and processes that impinge on aging are reviewed, and how they contribute to health and disease during aging is discussed. The evolution of this situation is analyzed, and the consequences for the study of genetic effects on aging are presented. Epigenetic programming of aging, as a continuation of development, creates an interface between the genome and the environment. New research into the gut microbiome describes how this interface may operate in practice with marked consequences for a variety of disorders. This analysis is bolstered by a view of the aging organism as a whole, with conclusions about the mechanisms underlying resilience of the organism to change, and is expanded with a discussion of circadian rhythms in aging. Finally, the book presents an outlook for the development of interventions to delay or to reverse the features of aging. The publication is recommended to students, researchers as well as professionals dealing with public health and public policy related to an aging society.

Book Description
Comprehension of the theories of aging requires rudimentary knowledge of oxidation and reduction reactions, protein function, cell organelles, mitosis, acquired immunity, and evolution, among other basic biological concepts. Without these fundamentals, students of biological aging struggle to learn the essentials of biological aging and how to appreciate the research advances in the field. Human Biological Aging: From Macromolecules To Organ-Systems is an introduction to human aging from the level of macromolecules to organ systems. Age changes in proteins, DNA, polysaccharides and lipids are discussed relative to known age-related alterations in structure and function produced by free radicals and oxidants. At the cellular level, age-dependent mechanisms that diminish organelle function are described. Cellular phenomena of replicative senescence apoptosis, autophagy and neuroplasticity are detailed as to their contribution to compromised cellular functions. Authored by a leader in the field, Human Biological Aging: From Macromolecules To Organ-Systems is an invaluable introduction for those studying human aging.

Book Description
With the world's population getting increasingly older, there has never been a more pressing need for the study of old age and ageing. An Introduction to Gerontology provides a wide-ranging introduction to this important topic. By assuming no prior expert knowledge and avoiding jargon, this book will guide students through all the main subjects in gerontology, covering both traditional areas, such as biological and social ageing, and more contemporary areas, such as technology, the arts and sexuality. An Introduction to Gerontology is written by a team of international authors with multidisciplinary backgrounds who draw evidence from a variety of different perspectives and traditions.

Book Description
Human Aging: From Cellular Mechanisms to Therapeutic Strategies offers an exhaustive picture of all the biological aspects of human aging by describing the key mechanisms associated with human aging and covering events that could disrupt the normal course of aging. Each chapter includes a summary of the salient points covered, along with futures prospects.
