Book Description
This work examines recent research in the biochemical basis of aging and offers contributions from an international group of researchers actively engaged in this field. It provides valuable new data on how aging alters protein metabolism and structure, the cell, endocrine and neurobiological functions, and free radicals. The book also explores the effects of dietary restrictions on aging. Specific topics include mechanisms of protein degradation; turnover of plasma membrane proteins in hepatocytes; genetic, biochemical, and molecular studies of cellular senescence; effects of aging and dietary restrictions on protein synthesis; and physiological antioxidant defense and repair systems.

Book Description
Aging is loosely defined as the accumulation of changes in an organism over time. At the cellular level such changes are distinct and multidimensional: DNA replication ceases, cells stop dividing, they become senescent and eventually die. DNA metabolism and chromosomal maintenance, together with protein metabolism are critical in the aging process. The focus of this book is on the role of protein metabolism and homeostasis in aging. An overview is provided of the current knowledge in the area, including protein synthesis, accuracy and repair, post-translational modifications, degradation and turnover, and how they define and influence aging. The chapters mainly focus on well-characterised factors and pathways, but new areas are also presented, where associations with aging are just being elucidated by current experimental data. Protein turnover, the balance between protein synthesis and protein degradation are carefully maintained in healthy cells. Chapters 1 and 2 illustrate that aging cells are characterised by alterations in the rate, level and accuracy of protein synthesis compared to young ones, and that mRNA translation, essential for cell growth and survival, is controlled at multiple levels. The theory that growth and somatic maintenance are believed to be antagonistic processes is described in Chapter 3: inhibition of protein synthesis results in decreased rates of growth and development, but also confers an extension of lifespan, as shown for example by the effects of dietary restriction in various models organisms.

Book Description
It is a commonly held belief that athletes, particularly body builders, have greater requirements for dietary protein than sedentary individuals. However, the evidence in support of this contention is controversial. This book is the latest in a series of publications designed to inform both civilian and military scientists and personnel about issues related to nutrition and military service. Among the many other stressors they experience, soldiers face unique nutritional demands during combat. Of particular concern is the role that dietary protein might play in controlling muscle mass and strength, response to injury and infection, and cognitive performance. The first part of the book contains the committee's summary of the workshop, responses to the Army's questions, conclusions, and recommendations. The remainder of the book contains papers contributed by speakers at the workshop on such topics as, the effects of aging and hormones on regulation of muscle mass and function, alterations in protein metabolism due to the stress of injury or infection, the role of individual amino acids, the components of proteins, as neurotransmitters, hormones, and modulators of various physiological processes, and the efficacy and safety considerations associated with dietary supplements aimed at enhancing performance.

Book Description
The Molecular Nutrition of Amino Acids and Proteins provides an in-depth look at the involvement and role of amino acids and proteins in molecular nutrition. Editor Dominique Dardevet has assembled a collection of chapters written by leading researchers and top professors that provide the reader with a comprehensive understanding of amino acids and proteins. The book provides an introduction to the fundamentals of amino acids and proteins as well as the composition of food. It then delves into the molecular biology of the cell and genetic machinery and its function. The Molecular Nutrition of Amino Acids and Proteins also features reference guides for terms and bullet-point summaries, making it readily accessible to novices while still providing the most up-to-date and detailed information that experienced researchers need. Provides a gentle introduction to the subject by first addressing nutritional information and then building in molecular aspects, clearly establishing fundamental information for the reader Facilitates reader comprehension by including succinct summary points in each chapter Contains a glossary of definitions that allows readers to easily reference terms Provides both a deep and broad understanding of the subject by containing overviews as well as detail-focused chapters

Book Description
This title includes a number of Open Access chapters. Sarcopenia—the loss of muscle mass and strength that occurs with advancing age—is a major health challenge, particularly in North America, Europe, and Japan, which have large aging populations. This compendium volume is a valuable addition to the existing literature, providing state-of-the-art information on the most effective prevention and treatment options. Included are research articles on nutrition management and the prevention of sarcopenia; protein therapy for sarcopenia; effect of exercise on sarcopenia; and other therapeutic strategies, including antioxidants and steroids.

Book Description
SARCOPENIA An in-depth examination of sarcopenia’s underexplored yet widespread impact within the field of gerontology Sarcopenia is common in older men and women, and yet awareness of its clinical relevance is still relatively low. Only formally included in the International Classification of Diseases in 2016, the condition may impact societies with serious health-related and financial consequences unless consistent, effective methods of identification and management are adopted. This second edition of Sarcopenia provides geriatricians and other healthcare professionals with a revised and expanded examination of this understudied and underdiagnosed condition. Edited by two leading authorities on the subject, it covers the epidemiology and diagnosis of sarcopenia, as well as treatment options and possible prevention strategies. Eight newly written chapters build upon existing knowledge with fresh data on topics including sarcopenia’s biomarkers and its impact on the healthcare economy. This important text: Defines sarcopenia and explains its clinical relevance Covers all recent scientific evidence Outlines treatment options Considers prevention strategies Discusses sarcopenia as a public health priority Features eight new chapters covering topics such as sarcopenia’s clinical management, its biomarkers, and its financial impact Containing vital information for clinicians and other professionals working in geriatric care, nursing homes, nutrition, cancer, endocrinology, surgery, sports medicine and many other specialties, Sarcopenia, second edition, is a groundbreaking and essential new resource.

Book Description
Biochemical Approaches to Aging covers the significant research studies on the biochemical aspects of aging. This book is composed of 11 chapters that consider several factors that affect cellular aging. The opening chapters present some model systems for the study of aging using different species, including mammals, nematodes, insects, and protozoa. The succeeding chapters deal with the role of free radical formation, lipid peroxidation, membranes, mitochondria, microsomes, and lysosomes in aging. These topics are followed by discussions of the DNA and RNA changes during aging; the mechanism of protein metabolism; and the alternation of proteins and enzymes. The concluding chapters examine the effect of aging on hormonal interaction and the biochemical effects of nutrition in aging. This book will prove useful to gerontologists, cell and molecular biologists, and researchers.
