Authoritative, wide ranging and thorough, this book will act as a source for experimental design, a comprehensive description of age related diseases, and provide information of the latest molecular theories underlying their causes. Additionally, it will target industries involved in developing anti-aging drugs, post-graduate medical students, and university libraries.
Aging: How Science Works
by Carsten Carlberg Eunike Velleuer Stine M. UlvenAging is a topic that concerns all of us, since none of us can escape it. The molecular and cellular process is built in every of the billions of cells forming our body. Some of these cells, such as immune cells and red blood cells, live only for a few days to weeks and get life-long constantly replaced by cells produced in the bone marrow. In contrast, there are cells, such as neurons and memory lymphocytes, that get as old as we get. The process of aging limits our maximal life span, which is for our humans 120 years. However, only a very few individuals reached this age. How did their life differ from others that died decades earlier? Is it just the absence of life threatening disease paired with a more healthy life style? Or is it build in in our genome or epigenome? In this book we try to give answers to these questions from the perspectives of evolution, our genome, the epigenomes of our different tissues and cell types and the functionality of our cells. We should try to understand ourselves in detail as well as in a global setting. Basic biology explains cellular mechanisms, such as growth, differentiation, and cell death, which make life as a whole possible. Every (human) organism represents a complex interplay between hundreds of different cell types forming distinctive tissues and organs with specialized tasks. These processes need to be highly orchestrated especially during development, maintenance and aging. Studying the cellular and molecular basis of aging is one of the most fascinating areas but also a great challenge. Nevertheless, research made the biggest steps in elucidating biological processes via studying malfunctions of normal mechanisms leading to different diseases, such as progeroid syndrome and cancer. We will start this book with the understanding of the human genome in relation to principles of evolution. Then we will explain the basics of gene regulation and epigenetics, i.e., the interplay of transcription factors and chromatin. Next, we will shift to cellular mechanisms of aging and discuss then the impact of nutrition and immunity on the aging process. In the following the relation of aging to so-called aging-related common diseases, such as type 2 diabetes, atherosclerosis, cancer and Alzheimer. Do we get these diseases because we are aging or are we aging because we get one of these diseases? The book will end how we can slow down the aging process so that we can age healthy. In short, healthy aging is not an option but is a must. An ancient poem says “Teach us to number our days, that we may get a heart of wisdom.” It is up to each one of us and a daily decision to live a healthy lifestyle and to be aware of the unique gift of live we all have.

SasserPresenting current research in an innovative format, Aging: Concepts and Controversies encourages students to become involved and take an informed stand on the major aging issues that we face as a society. Leading author and active expert in gerontology Rick Moody provides thorough explanation of the issues in the Concepts sections and current research in the Controversy sections, demonstrating the close link between concepts and controversies in these broad areas of aging: health care, socioeconomic trends, and the life course.
Aging and Age-Related Disorders (Oxidative Stress in Applied Basic Research and Clinical Practice)
by Stephen Bondy Kenneth MaieseFeatures that characterize the aging process include the gradual accumulation of cell damage after prolonged exposure to oxidative and inflammatory events over a lifetime. In addition to the accretion of lesions, the intrinsic levels of pro-oxidant and aberrant immune responses are elevated with age. These adverse events are often further enhanced by the chronic and slow progressing diseases that characterize the senescent brain and cardiovascular system. The incidence of some disorders such as Alzheimer's disease and vascular diseases are sufficiently prevalent in the extreme elderly that these disorders can arguably be considered "normal". Aging and Aging-Related Disorders examines the interface between normal and pathological aging, and illustrates how this border can sometimes be diffuse. It explores and illustrates the processes underlying the means by which aging becomes increasingly associated with inappropriate levels of free radical activity and how this can serve as a platform for the progression of age-related diseases. The book provides chapters that examine the interactive relationship between systems in the body that can enhance or sometimes even limit cellular longevity. In addition, specific redox mechanisms in cells are discussed. Another important aspect for aging discussed here is the close relationship between the systems of the body and exposure to environmental influences of oxidative stress that can affect both cellular senescence and a cell's nuclear DNA. What may be even more interesting to note is that these external stressors are not simply confined to illnesses usually associated with aging, but can be evident in maturing and young individuals. A broad range of internationally recognized experts have contributed to this book. Their aim is to successfully highlight emerging knowledge and therapy for the understanding of the basis and development of aging-related disorders.
Aging and Health in Africa (International Perspectives on Aging #4)
by Pranitha MaharajPopulation aging is a matter of global concern. It often occurs in tandem with changes in the health profile of the population. In Africa, many countries are already facing a high burden of communicable diseases. However, as more and more children survive childhood and move on to adult years and old age they are also more likely to experience health problems associated with the aging process. Population aging in Africa is occurring in the context of high levels of poverty, changing family structures, an immense disease burden, fragile health systems and weak or poorly managed government institutions. This book shows that aging is likely to lead to increased social and economic demands for the continent. However, most national governments in Africa have not begun to address the issue of how to respond effectively to the needs of the older population. This will require a better understanding of the socio-economic and demographic situation of the older population in Africa. This book fills the gaps that exist by exploring the social realities of population aging in Africa. It also focuses on the policy and programmatic responses, gaps and future challenges related to aging across the continent.
Aging and Lung Disease: A Clinical Guide (Respiratory Medicine)
by Margaret PisaniPeople age 65 and older are the fastest growing segment of the U.S. population. In the 2010 census 16% of the population, 50 million people, were age 65 and older. That number is projected to increase to 66 million by the year 2050. Life expectancy has also increased, with recent CDC reports indicating life expectancy at 77.9 years. Age-adjusted death rates have decreased significantly with the largest changes occurring in older patients. Despite these trends, the 10 leading causes of death include several pulmonary etiologies including lung cancer, chronic respiratory diseases, influenza and pneumonia. Aging and Lung Disease: A Clinical Guide is devoted to understanding the impact of respiratory diseases in older patients. It includes reviews of physiology of the aging lung, allergy and immunology of the aging, as well as sleep changes over the life cycle. There are also comprehensive reviews on specific disease topics including chronic obstructive lung disease, lung cancer, atypical mycobacteria, interstitial lung disease, pulmonary hypertension, pulmonary embolism, obstructive sleep apnea, sleep disorders in older patients. Two chapters focus on unique issues in older patients; HIV and lung transplant. Included also are important chapters on assessing functional and cognitive status and end-of-life issues in older patients with lung disease. In addition to outlining the current state of knowledge, each chapter focuses on special considerations when caring for older patients. Of particular interest to pulmonologists, internists, and gerontologists, other readers, such as pulmonary and geriatric nurse practitioners, as well as clinical researchers interested in both pulmonary and aging issues, will find Aging and Lung Disease: A Clinical Guide to be a vital resource for improving their care of older patients with lung disorders.
Aging Bones: A Short History of Osteoporosis (Johns Hopkins Biographies of Disease)
by Gerald N. GrobHow osteoporosis went from a normal aging process to a disease.In the middle of the twentieth century, few physicians could have predicted that the modern diagnostic category of osteoporosis would emerge to include millions of Americans, predominantly older women. Before World War II, popular attitudes held that the declining physical and mental health of older persons was neither preventable nor reversible and that older people had little to contribute. Moreover, the physiological processes that influenced the health of bones remained mysterious. In Aging Bones, Gerald N. Grob makes a historical inquiry into how this one aspect of aging came to be considered a disease.During the 1950s and 1960s, as more and more people lived to the age of 65, older people emerged as a self-conscious group with distinct interests, and they rejected the pejorative concept of senescence. But they had pressing health needs, and preventing age-related decline became a focus for researchers and clinicians alike.In analyzing how the normal aging of bones was transformed into a medical diagnosis requiring treatment, historian of medicine Grob explores developments in medical science as well as the social, intellectual, economic, demographic, and political changes that transformed American society in the post–World War II decades.Though seemingly straightforward, osteoporosis and its treatment are shaped by illusions about the conquest of disease and aging. These illusions, in turn, are instrumental in shaping our health care system. While bone density tests and osteoporosis treatments are now routinely prescribed, aggressive pharmaceutical intervention has produced results that are inconclusive at best. The fascinating history in Aging Bones will appeal to students and scholars in the history of medicine, health policy, gerontology, endocrinology, and orthopedics, as well as anyone who has been diagnosed with osteoporosis.
Aging, Health, and Longevity in the Mexican-Origin Population (Social Disparities In Health And Health Care Ser.)
by Jacqueline L. Angel Fernando Torres-Gil Kyriakos MarkidesAging, Health, and Longevity in the Mexican-Origin Population creates a foundation for an interdisciplinary discussion of the trajectory of disability and long-term care for older people of Mexican-origin from a bi-national perspective. Although the literature on Latino elders in the United States is growing, few of these studies or publications offer the breadth and depth contained in this book.
Aging in China: Implications to Social Policy of a Changing Economic State (International Perspectives on Aging #2)
by Jason L. Powell Sheying ChenChina, which is fast on its way to becoming the most powerful economic force in the world, has four unique characteristics that distinguish it from other countries in Asia: (1) The proportion of aging population is growing faster than that of Japan (the country previously recognized as having the fastest rate) and much faster than nations in western Europe. (2) An early arrival of an aging population before modernization has fully taken place, with social policy implications. It is certain that China will face a severely aged population before it has sufficient time and resources to establish an adequate social security and service system for older people. (3) There will be fluctuations in the total dependency ratio. The Chinese government estimates are that the country will reach a higher dependent burden earlier in the twenty-first century than was previously forecast. (4) The government's fertility policy (single child per family) and its implementation has a strong influence on the aging process. Fewer children are being born, but with more elderly people a conflict arises between the objectives to limit population increase and yet maintain a balanced age structure (Peng and Guo 2001). The intersection of these fourfold factors means that the increased aging population is giving rise to serious concerns among Chinese social policy makers. There is a chronic lack of good resource materials that attempt to make sense of social policy in its relationship to examining the problems and possibilities of human aging grounded in an analysis of economic of social policy in China and impact on rural and urban spaces. Such analysis of China will be covered by conceptual, theoretical, and empirical approaches. The book will also discuss substantive topics of housing, community care, family care, pensions, and mental health. The book brings together a truly world class array of researchers to provide discussions of critical implications of aging social policy and the economic impact in China.
Aging in Comparative Perspective: Processes and Policies (International Perspectives on Aging #1)
by Jamie Halsall Ian Gillespie CookThis book examines the key aging processes in seven countries (United States, United Kingdom, Sweden, Japan, China, Nepal, and South Africa) and the main policies that have been, and are being, developed to deal with this rapid change in the demographic profile. It addresses the problems that are identified as well as the positive aspects of aging within each of these contrasting societies. Thus it makes a significant contribution to the major debates about growing old across the globe.
Aging in European Societies: Healthy Aging in Europe (International Perspectives on Aging #6)
by Constantinos PhellasBetween longer life expectancies and declining birth rates, Europe's elder population is growing into a sizable minority with considerable impact on nations, health systems, and economies--in other words, global implications as well as local and regional ones. Those investing in the health of older adults need a double perspective: the social and clinical complexity of aging and the larger forces shaping these experiences. Aging in European Societies examines aging trends across the continent, analyzing individual and collective variables that affect the lives of older adults, and drawing salient comparisons with other parts of the world. An interdisciplinary panel of experts provides theory, research, and empirical findings (with examples from the UK, Cyprus, Sweden, and others) in key areas such as family and social supports, physical and cognitive changes, dependence and autonomy issues, and living arrangements. The book's wide-net approach offers insights into not only aging, but aging well. And of particular importance, it details approaches to defining and measuring the elusive but crucial concept, quality of life. Included in the coverage: The potential for technology to improve elders' quality of life.Dementia and quality of life issues.Changes in functional ability with aging and over time.Family networks and supports in older age.Factors influencing inequalities in quality of life.Late-life learning in the E.U. Gerontologists, sociologists, health and cross-cultural psychologists, and public health policymakers will welcome Aging in European Societies as a springboard toward continued discussion, new directions for research, and improvements in policy and practice.
Aging in Hong Kong: A Comparative Perspective (International Perspectives on Aging #5)
by Jean WooWith the longest life expectancy for men and the second longest for women, Hong Kong typifies our planet's aging population. The daily lives of its older adults closely match the advantages and disadvantages experienced by urban elders in other developed countries. For these reasons, Hong Kong's elderly serve as a salient guide to older people's social, psychological, and healthcare needs--concerns of increasing importance as the world grows older. Aging in Hong Kong examines this emblematic population as a case study specifically in comparison with their counterparts in the West, shedding light on diverse, interrelated currents in the aging experience. Referencing numerous international studies, the book contrasts different health service arrangements and social factors and relates them to a variety of health outcomes. Its wide-ranging coverage documents health and illness trends, reviews age-friendly policy initiatives, relates health literacy to patients' active role in their own care, and discusses elders as an underserved group in the division of limited health funding and resources. This multiple focus draws readers' attention to policies that need revisiting or retooling as chapters analyze major life areas including: Living environment.Retirement and post-retirement employment issues.Financial asset management.Health literacy regarding aging issues.Elder-positive service delivery models.Ageism in the prioritization of healthcare.End-of-life issues. By assembling such a wealth of data on its subject, Aging in Hong Kong puts ongoing challenges into clear focus for gerontologists, sociologists, health and cross-cultural psychologists, public health policymakers, and others involved in improving the quality of elders' lives.
Aging is a Group-Selected Adaptation: Theory, Evidence, and Medical Implications
by Joshua MitteldorfAlthough books exist on the evolution of aging, this is the first book written from the perspective of again as an adaptive program. It offers an insight into the implications of research on aging genetics, The author proposes the Demographic Theory of Senescence, whereby aging has been affirmatively selected because it levels the death rate over time helping stabilize population dynamics and prevent extinctions.
Aging Mechanisms II: Longevity, Metabolism, and Brain Aging
by Nozomu MoriThis book describes the recent advancement of basic research on the biology of aging and longevity studies in various organisms, as well as the neurobiology of aging and neurodegeneration mechanisms. Chapters present new findings and conceptual developments concerning the basic mechanisms of aging and longevity determination. As a follow-up volume to the previous book Aging Mechanisms (2015), it overviews the rapid progress of aging research introducing new topics from leading laboratories in Japan. Chapter contributors are selected based on recent scientific achievements on the mechanisms of aging in various model organisms, including yeast, worm (C. elegans), fly (Drosophila), mice, and rats. Chapters are ordered from the discussion on molecular and cellular levels to physiological and systemic levels. The book also provides an overview of aging science in the region and helps readers quickly grasp who is doing what in this research area. As the aging of population becomes an ever more pressing issue in Asia, advancing the understanding of basic mechanisms of organism aging and longevity determination will be crucial to developing more effective therapies and protective strategies. Researchers and graduate students in biomedical aging research will find this as a rich source of information and a stimulus to novel research directions.

It covers various maintenance, service and retrofit methods available to mitigate age-related deterioration of equipment. It also presents numerous configuration and automation upgrades at the system level that can deal with higher portions of aging equipment in the system and still provide good service at a reasonable cost.
Aging Research in Yeast (Subcellular Biochemistry #57)
by Michael Breitenbach Peter Laun S. Michal JazwinskiThis volume includes contributions by the leading experts in the field of yeast aging. Budding yeast (Saccharomyces cerevisiae) and other fungal organisms provide models for aging research that are relevant to organismic aging and to the aging processes occurring in the human body. Replicative aging, in which only the mother cell ages while the daughter cell resets the clock to zero is a model for the aging of stem cell populations in humans, while chronological aging (measured by survival in stationary phase) is a model for the aging processes in postmitotic cells (for instance, neurons of the brain). Most mechanisms of aging are studied in yeast. Among them, this book discusses: mitochondrial theories of aging, emphasizing oxidative stress and retrograde responses; the role of autophagy and mitophagy; the relationship of apoptosis to aging processes; the role of asymmetric segregation of damage in replicative aging; the role of replication stress; and the role of the cytoskeleton in aging. Modern methods of yeast genetics and genomics are described that can be used to search for aging-specific functions in a genome-wide unbiased fashion. The similarities in the pathology of senescence (studied in yeast) and of cancer cells, including genome instability, are examined.

The Aging Revolution: The History of Geriatric Health Care and What Really Matters to Older Adults
by Charles Kenney Michael J. Dowling Maria Torroella CarneyA history of aging in the United States and an innovative blueprint for revolutionizing care for older adults from Northwell Health, New York&’s largest health care system. The New York Times described Dr. Robert Butler as &“the man who saw old age anew.&” In his 1975 book Why Survive: Being Old in America, Butler argued that for far too many people old age was &“a period of quiet despair . . . and muted rage&” and he set out to mitigate it. Nearly five decades since he penned his book, a devoted band of brilliant physicians and others in the healthcare field have realized at least a portion of Butler&’s dream: to recognize and alleviate suffering among the aging.The Aging Revolution is the story of Butler and his disciples: women and men who saw older distressed adults in hospitals and homes, and worse: being ignored by most of the medical establishment. These revolutionaries could not ignore the suffering, and they set out—individually and collectively—to create entirely new ways of caring for aging adults to ease their suffering and improve their quality and length of life. This revelatory book tells a story never-before told in its entirety, recounting the one of the most significant periods of improvement in American medical history. Readers will learn about pioneering individuals, concepts, and ideas that have improved the lives of millions, including: the women who placed the spotlight on delirium and falls—major issues for older adults; the campaign to build and spread Geriatric and Palliative Care; the small bands of doctors who worked the halls of Congress to create a new program that provides primary care along with home visits from healthcare professionals; and the New York-based foundation that has devoted its mission and millions exclusively to improving care and quality of life for aging adults. Today, as a result, chronic conditions that almost always accompany old age are far more manageable. Older people enjoy more options for work and professional development, for education, for leisure and travel, for sports and maintaining physical strength and mobility. For increasing numbers of Americans, life is healthier and richer in the experiences that matter most. Yet, aging in America can still be a challenge and, too often, particularly for the poor, a painful struggle. The range of mental and physical well-being has almost infinite variations: ninety-year-olds running marathons; sixty-five-year-olds incapacitated by stroke. While this book celebrates the incredible progress and strides made in this field, it also highlights areas that need improvement. The authors lay out specific steps that, if implemented, could ignite the aging revolution and diminish the total volume of older adults suffering in America.
Aging, Shaking, and Cracking of Infrastructures: From Mechanics to Concrete Dams and Nuclear Structures
by Victor E. Saouma M. Amin Hariri-ArdebiliThis self-contained book focuses on the safety assessment of existing structures subjected to multi-hazard scenarios through advanced numerical methods. Whereas the focus is on concrete dams and nuclear containment structures, the presented methodologies can also be applied to other large-scale ones.The authors explains how aging and shaking ultimately lead to cracking, and how these complexities are compounded by their random nature. Nonlinear (static and transient) finite element analysis is hence integrated with both earthquake engineering and probabilistic methods to ultimately derive capacity or fragility curves through a rigorous safety assessment.Expanding its focus beyond design aspects or the state of the practice (i.e., codes), this book is composed of seven sections:Fundamentals: theoretical coverage of solid mechnics, plasticity, fracture mechanics, creep, seismology, dynamic analysis, probability and statisticsDamage: that can affect concrete structures, such as cracking of concrete, AAR, chloride ingress, and rebar corrosion,Finite Element: formulation for both linear and nonlinear analysis including stress, heat and fracture mechanics,Engineering Models: for soil/fluid-structure interaction, uncertainty quantification, probablilistic and random finite element analysis, machine learning, performance based earthquake engineering, ground motion intensity measures, seismic hazard analysis, capacity/fragility functions and damage indeces,Applications to dams through potential failure mode analyses, risk-informed decision making, deterministic and probabilistic examples,Applications to nuclear structures through modeling issues, aging management programs, critical review of some analyses,Other applications and case studies: massive RC structures and bridges, detailed assessment of a nuclear containment structure evaluation for license renewal. This book should inspire students, professionals and most importantly regulators to rigorously apply the most up to date scientific methods in the safety assessment of large concrete structures.
Agitator Design for Gas-Liquid Fermenters and Bioreactors
by Gregory T. BenzThis book is concise reference to designing mechanically sound agitation systems that will perform the process function efficiently and economically. Currently, all the books on bioreactor and fermenter design do not focus specifically on agitation. Sections cover agitator fundamentals, impeller systems, optimum power and air flow at peak mass transfer calculations, optimizing operation for minimum energy per batch, heat transfer surfaces and calculations, shaft seal considerations, mounting method, mechanical design, and vendor evaluation.
Agitator Design Technology for Biofuels and Renewable Chemicals
by Gregory T. BenzAgitator Design Technology for Biofuels and Renewable Chemicals Comprehensive guide to the design, installation, selection, and maintenance of agitators in the biofuels and renewable chemicals industries Agitator Design Technology for Biofuels and Renewable Chemicals is a single-source reference on all the major issues related to agitator design for biofuel, written with the intention of saving the reader time by avoiding the need to consult multiple references or sift through many pages of text to find what is needed for agitator design in specific industries. The work presents a brief introduction of basic principles and relevant theory, then goes on to cover the real-world applications of these principles, including economic evaluations of alternatives as well as supplier evaluation principles. To aid in quick and seamless reader comprehension, each chapter has the symbols used in that chapter listed and defined at the end. Overall, the work is written more as a how-to book than an academic treatise. The highly qualified author has included plenty of brevity throughout the pages with the hopes that readers go through the entire book as a single unit, rather than just skimming an occasional page or chapter as is common with other resources in similar fields. Sample topics covered in the work include: Avoiding common problems, such as using impeller diameters and speeds that would not result in even minimal solids suspension or liquid motion Choosing the right impellers for the job, understanding how power draw and pumping are calculated, and becoming familiar with biofuel/biomass agitator sizing guidelines The principles and limitations of scale-up and the most common non-Newtonian rheology applicable to biofuel applications Designing lab tests and scale-up cellulosic hydrolysis agitation, plus the uses and limitations of Computational Fluid Dynamics (CFD) As an easy-to-read and completely comprehensive resource to the subject, Agitator Design Technology for Biofuels and Renewable Chemicals is immensely valuable for professionals tasked with selecting agitation equipment or troubleshooting existing equipment, as well as those involved in planning activities and allocating resources related to project management.
