Aging And Aging Related Diseases

Ageing has become a great problem for many countries. Due to world-wide life prolongation the number of people over 6o years old has grown rapidly into a ten percent piece of the world population. The growing age of the world population raises many social, economical, and medical problems. The proportion of people in the economically active age groups to those who are over 65 is constantly decreasing. A major consequence of the increasing numbers of individuals in advanced age groups is increasing numbers of patients suffering from age-related diseases. The aim of this book is to present the basic data on human ageing as well as on age-related diseases.

This book offers a broad-ranging assessment of current efforts of the molecular, cellular, hormonal, nutritional and lifestyle strategies being tested and applied by biogerontologists in the search for effective means of intervention, prevention and treatment of age-related diseases, and for achieving healthy old age. Employing a semi-academic style, the book presents data from experimental systems, while focusing primarily on their applications to humans in the prevention and treatment of age-related impairments.

Features 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 of unicellular and multicellular eukaryotic organisms is a convoluted biological phenomenon, which is manifested as an age-related functional decline caused by progressive dysregulation of certain cellular and organismal processes. Many chronic diseases are associated with human aging. These aging-associated diseases include cardiovascular diseases, chronic obstructive pulmonary disease, chronic kidney disease, diabetes, osteoarthritis, osteoporosis, sarcopenia, stroke, neurodegenerative diseases (including Parkinson’s, Alzheimer’s, and Huntington’s diseases), and many forms of cancer. Studies in yeast, roundworms, fruit flies, fishes, mice, primates, and humans have provided evidence that the major aspects and basic mechanisms of aging and aging-associated pathology are conserved across phyla. The focus of this International Journal of Molecular Sciences Special Issue is on molecular and cellular mechanisms, diagnostics, and therapies and diseases of aging. Fifteen original research and review articles in this Special Issue provide important insights into how various genetic, dietary, and pharmacological interventions can affect certain longevity-defining cellular and organismal processes to delay aging and postpone the onset of age-related pathologies in evolutionarily diverse organisms. These articles outline the most important unanswered questions and directions for future research in the vibrant and rapidly evolving fields of mechanisms of biological aging, aging-associated diseases, and aging-delaying therapies.

This book provides an overview of recent advances in the study of aging and aging related diseases, discussing the topics at individual, organ, tissue, cell, and molecular levels. It also presents studies on the biomarkers of aging and anti-aging interventions. Aging has been becoming a global health problem. However it was not possible to determine aging as we usually diagnose a disease because there are few biomarkers for age estimation. Since ancient times, people have been seeking anti-aging substances and methods for achieving immortality, while the scientific study of aging has only existed for 100 years. This book appeals to researchers both in institutes and in pharmaceutical companies interested in further studies in this field.

This book focuses on the nutrients and nutraceuticals that promote active and healthy ageing – recently defined by the WHO as the process of development and maintenance of functional capacity that allows well-being at an advanced stage of life. There has been a rapid rise in the use of nutritional interventions as well as specific nutraceuticals in the management of multifactorial aspects of clinical health outcomes. Written by leading experts this book comprehensively discusses the various ageing phenotypes and age-related diseases. It also assesses the nutritional status of the elderly and the various epidemiological factors that influence it. It reviews the role of dietary fiber in disease-free and fully functional ageing. Further, the book explores the benefits of polyphenols, which are secondary plant metabolites, in protecting against cancer, cardiovascular diseases, and various neurodegenerative diseases.

Aging is a natural phenomenon that is peculiar to all living things. However, accumulating findings indicate that senescence could be postponed or prevented by certain approaches. Substantial evidence has emerged supporting the possibility of radical human health and lifespan extension, in particular through pharmacological modulation of aging. A number of natural dietary ingredients and synthetic drugs have been assumed to have geroprotective potential. In the development of anti-aging therapeutics, several cell, insect, and animal models may provide useful starting points prior to human studies. This book provides an overview of current research aimed to search for life-extending medications and describes pharmacological aspects of anti-aging medicine. Readers are introduced to the fascinating historical background of geroprotection in the first chapter. In-depth information on models for investigating geroprotective drugs precedes a section covering anti-aging properties of pharmaceutical compounds, such as calorie restriction mimetics, autophagy inducers, senolytics and mitochondrial antioxidants. Finally, strategies to translate discoveries from aging research into drugs and healthcare policy perspectives on anti-ageing medicine are provided to give a complete picture of the field. A timely and carefully edited collection of chapters by leading researchers in the field, this book will be a fascinating and useful resource for pharmacologists, gerontologists and any scientifically interested person wishing to know more about the current status of research into anti-aging remedies, challenges and opportunities.
