Book Description
Molecular Basis of Aging is a collection of papers that discuss the molecular aspects of aging in the light of molecular biology, biochemical gerontology, and genetics. Each chapter of the book contains a different study about the topic, which includes the effects of aging on DNA synthesis; the amplification of extrachromosomal circular copies and mitochondrial DNA during aging; and the altered actions of hormones and neurotransmitters during aging. The book also encompasses the loss of responsiveness to growth factors in cell senescence; the integration of cellular-molecular and neuroendocrine concepts of aging; changes and inactivation of enzymes during aging; and the relationship of aging with free radicals. The text is recommended for molecular biologists, biochemists, and gerontologists who wish to study further the effects of aging on the body on a molecular level.

Book Description
Numerous studies had been performed to elucidate the mechanisms of aging and to achieve rejuvenation, with some success reported in recent years. However, at present, the findings from those studies are not sufficient to resolve the issue of aging. This book presents an overview of recent topics on cellular aging and rejuvenation. In the early chapters, the molecular mechanisms of aging via the activities of clock and ion channel proteins, in addition to overall aspects, are discussed. In the latter part, the aging of the skin, immune system, and brain is discussed. This book will prove useful for those studying or developing new drugs to counter the aging process and will encourage the development of novel ideas for rejuvenation.

Book Description
Molecular Genetic Mechanisms in Development and Aging discusses the mechanisms of aging at the level of the genome. This book explores the fundamental knowledge concerning the regulation and expression of gene, which is derived from investigations on microbial organisms. Organized into nine chapters, this book starts with an overview of the molecular genetic basis for the processes of aging. This text then explores the highly complex multicellular members of the class Insecta, which provide the researcher with many distinct and unique advantages for aging studies. Other chapters discuss the mechanisms of genetic control and organization during the development and aging of eukaryotes, which pose some challenging problems in cellular and developmental biology. The final chapter deals with the limitations of previous studies, including the lack of comparability due to differences in techniques, the measuring of free amino acid titers in hemolyph only, and differing diet and environmental variations. Biologists and students interested in developmental and molecular genetics will find this book useful.

Book Description
An individual's healthspan can be defined as the length of time an individual is able to maintain good health. In 2007, over one hundred experts and researchers from public and private institutions across the nation convened to find new ways of addressing the human healthspan and the elusive nature of aging. Experts in public health, bioengineering, neuroscience and gerontology discussed how stress and lifestyle influence the decline of health at older ages. Other discussions focused on the integration of technology in the quality of life, gerontology, regenerative medicine and life expectancy with regard to social and behavioral traits. Still, other groups explored topics such as the cellular and molecular mechanisms of biological aging, the effects of exercise on the human healthspan, and changes in social context to enhance functional status of the elderly. Most importantly, experts agreed that it was imperative to ensure that the elderly have access to medical services by establishing relationships with health care and insurance providers.

Book Description
Our skin changes as we age. It becomes thinner and loses fat, making it less plump and smooth. Clinically, aged skin is characterized by wrinkles, sagging, age spots and dryness. Emphasizing laboratory and clinical research, this book comprehensively describes the molecular mechanisms of human skin-aging and age-related skin diseases. This includes molecular understanding of the development of aging skin and its prevention as well as mechanisms-based clinical rejuvenation. The book also focuses on research to develop mechanisms-based anti-skin-aging products.

Book Description
Aging represents a physiological and per se non-pathological and multifactorial process involving a set of key genes and mechanisms being triggered by different endogenous and exogenous factors. Since aging is a major risk factor in connection with a variety of human disorders, it is increasingly becoming a central topic in biochemical and medical research. The plethora of theories on aging – some of which have been discussed for decades – are neither isolated nor contradictory but instead can be connected in a network of pathways and processes at the cellular and molecular levels. This book summarizes the most prominent and important approaches, focusing on telomeres, DNA damage and oxidative stress as well as on the possible role of nutrition, the interplay between genes and environment (epigenetics) and intracellular protein homeostasis and introduces some genes that have actually extended life spans in animal models. Linking these different determinants of aging with disease, this volume aims to reveal their multiple interdependencies. We see that there is no single “perfect” theory of aging and that instead it is possible to define what the authors call the molecular aging matrix of the cell. A better knowledge of its key mechanisms and the mutual connections between its components will lead to a better understanding of age-associated disorders such as Alzheimer’s disease.

Book Description
Stem Cells and Aging covers what is known about the effect of time and age on the basic units of life, which are the corresponding tissue-specific or adult stem cells. Even though the concept of stem cells was introduced nearly a century ago by Alexander Maximow, modern stem-cell research began in 1963 when James Till, Ernest McCullough and Lou Siminovitch established assays to detect hematopoietic stem cells. In fact, given the importance of the aging-associated diseases, scientists have developed a keen interest in understanding the aging process as they attempt to define the role of dysfunctional stem cells in the aging process. With an aging population worldwide, understanding these age-related stem cell changes at a basic biology level and at the level of their influences for regenerative medicine is of interest and importance. There is increasing evidence that the aging process can have much adverse effects on stem cells. In the modern era, one of the emerging fields in treating human diseases is stem cell research, as stem cells have the remarkable potential to treat a wide range of diseases. Nevertheless, understanding the molecular mechanism involved in aging and deterioration of stem cell function is crucial in developing effective new therapies for aging. Serves as an ideal reference to guide investigators toward valuable answers to the problems of our aging population Addresses the effect of time and age on human stem cells Includes chapters from contributors exploring the biology of stem cell aging around the globe

Book Description
Telomere shortening represents one of the basic aspects of ageing and telomere dysfunction could contribute to the accumulation of DNA damage during ageing. This book summarizes evidence and data indicating that telomere dysfunction influences human ageing, diseases and cancer. The book describes our current knowledge on checkpoints that limit cellular lifespan and survival in response to telomere dysfunction. There is special focus on adult stem cells.

Book Description
This volume of the subcellular Biochemistry series will attempt to bridge the gap between the subcellular events that are related to aging as they were described in the first volume of this set of two books and the reality of aging as this is seen in clinical practice. All chapters will start from the biochemistry or cell biology, where the data is available and work up towards the understanding that we have of aging in the various areas that are related to the subject. Key focus points for this volume are nutrition, external factors and genetics on aging. There will also be chapters that will focus on various organs or tissues in which aging has been well studied, like the eyes, the muscles, the immune system and the bones. The aim of the book project and the book project that is published in concert with this volume is to bring the subcellular and clinical areas into closer contact.
