Book Description
During our short time on earth, we all undergo the highly complex process of aging, and with it, we experience the many physiological symptoms. Studies of premature aging have produced a great deal of information that gives some aspects of aging a better understanding. This book explores Werner's syndrome. To some, Werner's syndrome is considered a caricature of aging, but others will find it fascinating that only one mutated human gene (WRN) can bring about a multitude of complicated phenotypes that are usually associated with aging.

Book Description
Helicases are ubiquitous enzymes found throughout evolution. Research in the helicase field has been going on for a long time now but in recent past with the completion of so many genomes, these enzymes have been discovered in a number of organisms. But the available literature is scattered. The huge number of identified DNA and RNA helicases, along with the structural and functional differences among them, make difficult for the interested scholar to grasp a comprehensive view of the field. Helicases from all Domains of Life is the first book to compile information about helicases from many different organisms in one place. Knowledge of the functions and features of helicases across the different kingdoms of life are a valuable source of novel ideas and information The book begins with a chapter on the evolutionary history of helicases followed by three "overview" chapters: one for bacteria/archaea (which are not mentioned), one for plants/algae and one for human helicases The overview chapters are followed by specific chapters on selected helicases of great importance from a biological/applicative point of view

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
The human hypothalamus, a small structure at the base of the brain, has strategic importance for the harmonic function of the human body. It controls the autonomic nervous system, neuroendocrine function, circadian and circannual rhythms, somatic activities, and behavior, and is situated at the borders between the brain and the body and the brain and the soul, meeting points for mind and body. The hypothalamus is involved in a wide range of higher mental functions, including attention, learning and reinforcement of mnemonic processes, emotional control, mood stability, and cognitive-emotional interactions. It also has a role to play in behavioral disorders, panic reactions, cluster headache, gelastic epilepsy, mental deficiency, periodic disorders, depression, autism, and schizophrenia, and in a substantial number of neurodegenerative diseases. It enlarges greatly the dimensions of the hypothalamic contribution in controlling psychosomatic equilibrium and retaining internal unity of the human existence.

Book Description
The world population is rapidly aging—it is estimated that by 1950, around 17% of the population will be elderly. In this context, aging involves several physiological, psychological and highly complex social processes that vary from one person to another. For a long time, medical care for older adults has focused on treating chronic, age-related diseases and their associated consequences. Recently, biomedical research brings a novel point of view to develop more effective interventions by targeting the aging process itself rather than separate conditions. There is a growing number of reports indicating that aging is driven by several interconnected mechanisms and biological components referred to as the molecular pillars of aging. Interfering with these mechanisms could help to treat, prevent, and understand the development of age-related diseases and associated syndromes. This book provides a clinical perspective and general update on biomedical and genetic research in aging, moving from an update in the molecular pillars of aging to a perspective of the most recent pharmacological, clinical, and diagnostic applications using genomic approaches and techniques. While this book focuses on the specifics of genetics and genomics, it also adopts a clinical perspective of geroscience, which seeks to understand the genetic, molecular and cellular mechanisms that make aging an important risk factor and, sometimes, a determining factor in the diseases and common chronic conditions of older people. Additionally, Clinical Genetics and Genomics of Aging is a significant contribution to support aging research, as it shows that collaboration across disciplines is relevant to progress in the field. As more and more people benefit from increased longevity, clinician and researchers will be empowered by this knowledge to contribute to the progress of aging research.

Book Description
Recent 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.
