Book Description
Experts in the fields of energy metabolism, aging and oxidative stress provide an integrated view of how mechanisms involved in regulating energy metabolism are linked to fundamental processes of aging including cellular stress resistance and free radical production. During evolution signal transduction pathways and organ systems have been optimised for the efficient seeking, ingestion, storing and using of energy. These signalling pathways play prominent roles in lifespan determination with insulin and related signalling pathways being prime examples. The authors consider how lifespan and healthspan can be extended through knowledge of energy metabolism with the experimental model of dietary restriction being one example. The information in this volume of ACAG will foster novel approaches and experiments for further understanding the roles of energy metabolism in aging and disease.

Book Description
Humanity is aging. In the last century, life expectancy has increased by as much as 25 years, the greatest increase in 5'000 years of history. As a consequence the elderly constitute today the fastest growing segment of the world's population. This new situation creates many social problems and challenges to health care which both the developed as well as the developing countries will have to cope with. The present publication shows that scientific progress has reached a level where nutritional interventions may play a decisive part in the prevention of degenerative conditions of age, improvement of quality of life and impact on health care burden and resources. Topics deal with such different aspects as the influence of prenatal and early infant nutrition on the future aged individual and effects of energetic restriction on longevity. Further contributions include studies on mitochondrial alterations, digestive problems, specific metabolic deviations mediated by insulin, bone degradation, structural changes, neuromuscular dysfunctions, mental state of the elderly as well as the response of the immune system to nutrient intake. Finally the book offers a review of requirements appropriate to meet the age-related public health challenges of the 21st century.

Book Description
This book is about the importance of animal size. We tend to think of animal function in chemical terms and talk of water, salts, proteins, enzymes, oxygen, energy, and so on. We should not forget, however, that physical laws are equally important, for they determine rates of diffusion and heat transfer, transfer of force and momentum, the strength of structures, the dynamics of locomotion, and other aspects of the functioning of animal bodies. Physical laws provide possibilities and opportunities for an organism, yet they also impose constraints, setting limits to what is physically possible. This book aims to give an understanding of these rules because of their profound implications when we deal with animals of widely different size and scale. The reader will find that the book raises many questions. Remarkable and puzzling information makes it read a little like a detective story, but the last chapter, instead of giving the final solution, neither answers all questions nor provides one great unifying principle.

Book Description
Two thousand years ago, the average life expectancy from birth to death of a Roman citizen, an individual better off than most people at that time, was about 22 years (wars, infectious diseases, trauma, etc.). This progressively increased to about 47 years in the U.S. and most European countries by 1900. Today, the average life expectancy in the U.S. is 78 years (women about five years more than men). However, unless the obesity pandemic is reversed and lifestyles improved, the average life expectancy will likely decrease significantly. conversely, if our lifestyles improve, the average life expectancy could reach 85 or more years. Growing older does not necessarily mean growing sicker. Thus, "don't just add years to your life, add life to your years" (Hans Selve). Indeed, of the 15 major causes of death in the U.S., 65-70% are lifestyle-related. In this book, the following documented topics that are associated with diseases and mortality are discussed in detail: theories of aging; diseases and mortality associated with obesity, physical inactivity and poor nutrition; psychological stress (anxiety, depression); addiction (alcohol, tobacco, drugs); violence (suicide, homicide); food-borne and infectious diseases (viral, bacterial, parasitic); and various other conditions (air pollution, asbestosis, trace metals).

Book Description
The New York Times bestselling book coauthored by the Nobel Prize winner who discovered telomerase and telomeres' role in the aging process and the health psychologist who has done original research into how specific lifestyle and psychological habits can protect telomeres, slowing disease and improving life. Have you wondered why some sixty-year-olds look and feel like forty-year-olds and why some forty-year-olds look and feel like sixty-year-olds? While many factors contribute to aging and illness, Dr. Elizabeth Blackburn discovered a biological indicator called telomerase, the enzyme that replenishes telomeres, which protect our genetic heritage. Dr. Blackburn and Dr. Elissa Epel's research shows that the length and health of one's telomeres are a biological underpinning of the long-hypothesized mind-body connection. They and other scientists have found that changes we can make to our daily habits can protect our telomeres and increase our health spans (the number of years we remain healthy, active, and disease-free). The Telemere Effect reveals how Blackburn and Epel's findings, together with research from colleagues around the world, cumulatively show that sleep quality, exercise, aspects of diet, and even certain chemicals profoundly affect our telomeres, and that chronic stress, negative thoughts, strained relationships, and even the wrong neighborhoods can eat away at them. Drawing from this scientific body of knowledge, they share lists of foods and suggest amounts and types of exercise that are healthy for our telomeres, mind tricks you can use to protect yourself from stress, and information about how to protect your children against developing shorter telomeres, from pregnancy through adolescence. And they describe how we can improve our health spans at the community level, with neighborhoods characterized by trust, green spaces, and safe streets. The Telemere Effect will make you reassess how you live your life on a day-to-day basis. It is the first book to explain how we age at a cellular level and how we can make simple changes to keep our chromosomes and cells healthy, allowing us to stay disease-free longer and live more vital and meaningful lives.

Book Description
This new edition of Bioenergetics presents a clear and up-to-date explanation of the chemiosmotic theory and covers mitochondria, bacteria, and chloroplasts. It takes account of the many newly determined structures, such as ATP synthase and the two photosystems of photosynthesis, that provide molecular insight into chemiosmotic energy transduction. This edition includes additional color figures of protein structures and many newly drawn illustrations designed to enable the reader to grasp the fundamental insights that are derived from knowing the structure. Every chapter has been extensively revised and updated and a new chapter on the study of the bioenergetics of mitochondria in the intact cell is included to satisfy the enormous interest in this topic. Written for students and researchers alike, this book is the most current text on the chemiosmotic theory and membrane bioenergetics available.Key Features* Chapter on the study of bioenergetics of mitochondria in the intact cell* Appendix listing protein structure resources* Additional colour plates of protein structures* Many newly drawn illustrations* Website

Book Description
Just as the health costs of aging threaten to bankrupt developed countries, this book makes the scientific case that a biological "bailout" could be on the way, and that human aging can be different in the future than it is today. Here 40 authors argue how our improving understanding of the biology of aging and selected technologies should enable the successful use of many different and complementary methods for ameliorating aging, and why such interventions are appropriate based on our current historical, anthropological, philosophical, ethical, evolutionary, and biological context. Challenging concepts are presented together with in-depth reviews and paradigm-breaking proposals that collectively illustrate the potential for changing aging as never before. The proposals extend from today to a future many decades from now in which the control of aging may become effectively complete. Examples include sirtuin-modulating pills, new concepts for attacking cardiovascular disease and cancer, mitochondrial rejuvenation, stem cell therapies and regeneration, tissue reconstruction, telomere maintenance, prevention of immunosenescence, extracellular rejuvenation, artificial DNA repair, and full deployment of nanotechnology. The Future of Aging will make you think about aging differently and is a challenge to all of us to open our eyes to the future therapeutic potential of biogerontology.
