DOWNLOAD EBOOKStem 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

DOWNLOAD EBOOKNew Research on Cell Aging and Death reviews previous literature to describe the main behavioral and biochemical characteristics of the SAMP8 mouse model, discussing its main advantages as well as potential weaknesses to model age-related diseases. The subsequent chapter discusses the effect of the mechanism of cell death of neutrophil granulocytes on the realization of the inflammatory process. Neutrophil granulocytes play a central role in the innate nonspecific defense response of the human organism. In addition, neutrophils infiltrate secondary lymphoid organs where they regulate the development of adaptive immunity. Later, the authors suggest that in C. albicans, apoptotic mechanisms are valuable as major strategies with several characteristics such as phosphatidylserine exposure, DNA fragmentation, and activation of metacaspase. Studying antifungal agents with varying mechanisms of action can be effective in appropriately treating potentially fatal candidiasis. In one study, the authors evaluated the effects of natural and chemical compounds on promoter activities of several human DNA repair-associated genes in HeLa S3 cells. . The results indicated that naturally occurring compounds, for example, trans-resveratrol, upregulate TP53 promoter activity. Sustaining an appropriate level of genes encoding DNA repair factors is thought to be necessary for cell survival by preventing the accumulation of DNA mismatches and epigenetic alterations. The concluding review focuses on the effects of aging on adult neurogenesis, a process of producing new neurons from neural stem cells and neural progenitor cells in the neocortex, comparing the dentate gyrus and subventricular zone.

DOWNLOAD EBOOKThis new volume in the Subcellular Biochemistry series will focus on the biochemistry and cellular biology of aging processes in human cells. The chapters will be written by experts in their respective fields and will focus on a number of the current key areas of research in subcellular aging research. Main topics for discussion are mitochondrial aging, protein homeostasis and aging and the genetic processes that are involved in aging. There will also be chapters that are dedicated to the study of the roles of a variety of vitamins and minerals on aging and a number of other external factors (microbiological, ROS, inflammation, nutrition). This book will provide the reader with a state of the art overview of the subcellular aging field. This book will be published in cooperation with a second volume that will discuss the translation of the cell biology of aging to a more clinical setting and it is hoped that the combination of these two volumes will bring a deeper understanding of the links between the cell and the body during aging.

DOWNLOAD EBOOKCellular AGING AND CELL DEATH Edited by Nikki J. Holbrook, George R. Martin, and Richard A.Lockshin Cellular Aging and Cell Death provides a thorough understanding ofthe mechanisms responsible for cellular aging, covering the recentresearch on programmed cell death and senescence, and describingtheir role in the control of cell proliferation and the agingprocess. This one-of-a-kind book is the first to combine the twohottest research areas of cell biology into one comprehensivetext. Leading experts contribute to give readers an authoritativeoverview of the distinct fields of cellular aging and programmedcell death, as well as to demonstrate how both fields are criticalto understanding the aging process. They address the large andgrowing interest in apoptosis, especially with regard to themolecular signals that induce and regulate programmed cell death,and the role of apoptosis in a variety of age-associated diseasesand disabilities. Throughout the book, a strong emphasis is placedon the interrelationship of the molecular, cellular, andphysiological aspects of senescence. Individual chapters discuss such topics as the role and regulationof apoptosis in development, the potential impact of cell death onsuch postmitotic tissues as nerve and muscle, and suggest thatprogrammed cell death plays an important role in both pathologicaland nonpathological aspects of aging, including neurodegenerativediseases. One important chapter focuses on the most recent research involvingthe study of telomeres, whose reduction in length with age and celldivision may underlie cellular senescence. The subject of neuronalcell death is also put into the perspective of aging. Cellular Aging and Cell Death bridges the rapidly growing fields ofcellular aging and programmed cell death. This thorough, yetconcise book will be of particular interest to graduate studentsand researchers within the fields of cell and developmentalbiology, neurobiology, immunology, and physiology. Physicians andmedical students involved in the fields of gerontology andpathology will also find this an informative reference.

DOWNLOAD EBOOKCells, Aging, and Human Disease is the first book to explore aging all the way from genes to clinical application, analyzing the fundamental cellular changes which underlie human age-related disease. With over 4,000 references, this text explores both the fundamental processes of human aging and the tissue-by-tissue pathology, detailing both breaking research and current state-of-the-art clinical interventions in aging and age-related disease. Far from merely sharing a common onset late in the lifespan, age-related diseases are linked by fundamental common characteristics at the genetic and cellular levels. Emphasizing human cell mechanisms, the first section presents and analyzes our current knowledege of telomere biology and cell senescence. In superb academic detail, the text brings the reader up to date on telomere maintenance, telomerase dynamics, and current research on cell senescence--and the general model--cell senescence as the central component in human senescence and cancer. For each human malignancy, the chapter reviews and analyzes all available data on telomeres and telomerase, as well as summarizing current work on their clinical application in both diagnosis and cancer therapy. The second edition, oriented by organs and tissues, explores the actual physiological impact of cell senescence and aging on clinical disease. After a summary of the literature on early aging syndromes--the progerias--the text reviews aging diseases (Alzheimer's dementia, osteoarthritis, atherosclerosis, immune aging, presbyopia, sarcopenia, etc.) in the context of the tissues in which they occur. Each of the ten clinical chapters--skin, cardiovascular system, bone and joints, hematopoetic and immune systems, endocrine, CNS, renal, muscle, GI, and eyes--examines what we know of their pathology, the role of cell sensescence, and medical interventions, both current and potential.

DOWNLOAD EBOOKRecent studies have indicated that epigenetic processes may play a major role in both cellular and organismal aging. These epigenetic processes include not only DNA methylation and histone modifications, but also extend to many other epigenetic mediators such as the polycomb group proteins, chromosomal position effects, and noncoding RNA. The topics of this book range from fundamental changes in DNA methylation in aging to the most recent research on intervention into epigenetic modifications to modulate the aging process. The major topics of epigenetics and aging covered in this book are: 1) DNA methylation and histone modifications in aging; 2) Other epigenetic processes and aging; 3) Impact of epigenetics on aging; 4) Epigenetics of age-related diseases; 5) Epigenetic interventions and aging: and 6) Future directions in epigenetic aging research. The most studied of epigenetic processes, DNA methylation, has been associated with cellular aging and aging of organisms for many years. It is now apparent that both global and gene-specific alterations occur not only in DNA methylation during aging, but also in several histone alterations. Many epigenetic alterations can have an impact on aging processes such as stem cell aging, control of telomerase, modifications of telomeres, and epigenetic drift can impact the aging process as evident in the recent studies of aging monozygotic twins. Numerous age-related diseases are affected by epigenetic mechanisms. For example, recent studies have shown that DNA methylation is altered in Alzheimer’s disease and autoimmunity. Other prevalent diseases that have been associated with age-related epigenetic changes include cancer and diabetes. Paternal age and epigenetic changes appear to have an effect on schizophrenia and epigenetic silencing has been associated with several of the progeroid syndromes of premature aging. Moreover, the impact of dietary or drug intervention into epigenetic processes as they affect normal aging or age-related diseases is becoming increasingly feasible.

DOWNLOAD EBOOKThis 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.
