Download or read book Innovative Medicine written by Kazuwa Nakao and published by Springer. This book was released on 2015-10-13 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is devoted to innovative medicine, comprising the proceedings of the Uehara Memorial Foundation Symposium 2014. It remains extremely rare for the findings of basic research to be developed into clinical applications, and it takes a long time for the process to be achieved. The task of advancing the development of basic research into clinical reality lies with translational science, yet the field seems to struggle to find a way to move forward. To create innovative medical technology, many steps need to be taken: development and analysis of optimal animal models of human diseases, elucidation of genomic and epidemiological data, and establishment of “proof of concept”. There is also considerable demand for progress in drug research, new surgical procedures, and new clinical devices and equipment. While the original research target may be rare diseases, it is also important to apply those findings more broadly to common diseases. The book covers a wide range of topics and is organized into three complementary parts. The first part is basic research for innovative medicine, the second is translational research for innovative medicine, and the third is new technology for innovative medicine. This book helps to understand innovative medicine and to make progress in its realization.
Download or read book The Aging Immune System and Health written by Valquiria Bueno and published by Frontiers Media SA. This book was released on 2020-01-15 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world population presents an increased percentage of individuals over 65 years old and the fastest growing subgroup is over 85 years old. The increase in life expectancy observed in the last century has not been synonymous with extra years lived in good health (disability-free years). Population studies have shown that as individuals age, they can present a great heterogeneity of ability and health. Therefore, aging has been associated for some individuals with disabilities and hospitalizations. Deaths related to infectious pathogens are increased in the aging population mainly due to pneumonia and influenza whereas Cytomegalovirus, Epstein-Barr virus, among other viruses seem to contribute to the low-grade inflammatory process observed (inflammaging). Aging is a complex and multifactorial process in which functions of the organism are adjusted (remodelled) in order to deal with damaging events during life. One of the most important changes in aging individuals occurs in the immune system (innate and adaptive responses) with consequences such as poor response to new infections and vaccinations; increased susceptibility to cancer development and autoimmune diseases; frailty, and organ dysfunction. In addition, it has been proposed that immunosenescence not only reflects the aging of the organism but also contributes to this process. Bone marrow presents decreased hematopoiesis, the thymus undergoes involution and lymphoid organs (lymph nodes, spleen) also present reduced functionality. Therefore, cells derived, matured, or residing in these tissues decline in number and function. These changes have been identified in experimental models, in vitro conditions, peripheral blood, and biopsies via biomarkers such as cell phenotype, stimulus-induced proliferation, cytokines and antibodies levels. Telomere length and telomerase activity also decline in bone marrow-derived and peripheral blood cells and have been shown to play a role in immunosenescence. More recently, the investigation of short non-coding RNA molecules (microRNAs; miRNAs) pointed to this system as a possible control of aging-related mechanisms. Data obtained on these markers for aging individuals could lead to the generation of a marker panel for pathology prediction, to indicate interventions, and to evaluate the efficacy of interventions. Interventions such as nutrition supplements, exercise, vaccination (different dose, concentration of antigen, adjuvants) have been proposed to circumvent age-related diseases. Considering the heterogeneity in the aging process, further investigation is vital before the indication of interventions for aging individuals. As the extension of life expectancy is a reality, it is a challenge to understand how the aging population copes with the remodelling of the organism and how interventions could provide longevity in good health.

Download or read book Immunoregulatory Role of Thymus written by Marek P. Dabrowski and published by CRC Press. This book was released on 2019-06-04 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: First published in 1990. This important new text covers a wide area of thymology in both the theoretical and practical aspects. In view of current information, a crucial role of endocrine thymus is presented in the creation, maintenance, and senescence of neuro-endocrine-immune homeostasis. In particular, mechanisms are described (which are basically responsible for the T cell maturation and selection) for the hierarchic organization of the immune system and its thymic dependent immune competence in terms of tolerance and immunity. A detailed presentation of the structure and biological properties of a number of well-defined thymic hormones is included. Their clinical applications and results obtained in inherited or acquired immunodeficiencies and in neoplasmic diseases are also reviewed on the grounds of numerous representative clinical trials. A perspective and potential scope of immunorestorative therapy and prevention with thymic hormones and other thymomimetic drugs are outlined. Researchers, practitioners, and students will find this book to be a useful and essential source of information.
Download or read book The Human Thymus written by H.K. Müller-Hermelink and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: Twenty-five years have passed since J. MILLER'S basic work on the central role of the thymus for the generation of immunological reactivi ty. During this time, the abundance of fascinating literature on the immunological and functional aspects of this organ has been in contrast to the paucity of reports on its role in pathology. The causal or formal pathogenesis even of many of the well-documented pathological fea tures is so far unexplained or at least uncertain. In spite of some concep tual progress related to the work of CASTLEMAN, LEVINE, and ROSAI, we regrettably have to say that in pathology the thymus remains almost as inconspicuous as 25 years ago. Only the new techniques developed in recent years have made it possible to look as closely into the complicated structural organization of the thymus as it appears to be necessary to observe and document abnormalities. Major steps have been taken with the advent of mono clonal antibody immune histochemistry and with detailed ultrastructur al studies in embryology. At this point, pathologists and researchers with a special interest in the thymus were asked to give overviews of their respective fields of interest in light of recent findings in immunology and basic insights into the structural-functional interrelationship of the human thymus. The results of this initiative have been brought together in this volume.
Download or read book Thymic Senescence written by Krisztian Kvell and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thymic senescence develops in every person, although at different pace. Thymic senescence significantly lowers the production of naive T cells, leading to increased incidence of infections, cancer and autoimmune diseases. Certain external factors can accelerate thymic senescence. These include chemicals (copper-chelators), hormones (androgens), infections (viruses, fungi, protozoa). Others may slow the aging process of the thymus including perturbations to the hormonal (sex-steroid) system, genetic alterations (PPARgamma deficiency) or chemical compounds (PPARgamma antagonists). Thymic senescence research may provide insight to underlying molecular events and potentially appoint novel therapeutic targets for senescence intervention strategies. These hold promise to postpone thymus senescence and enhance T cell production. That would result in a decreased incidence of infections, cancer and autoimmune diseases, currently affecting the elderly. The attributed drop in healthcare costs and gain in quality of life share tremendous economic and social interest.
Download or read book Frailty written by Roger A. Fielding and published by Karger Medical Scientific. This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The demographic shift in the average age of the population worldwide calls for careful attention to the nutritional and health needs of the elderly. Frailty has been associated with increased disability, postsurgical complications and increased mortality; in a frail state, older adults are at greater risk for adverse outcomes, including falls and admissions to hospital and nursing homes. Despite the strong associations between frailty and subsequent poor outcomes, limited attention to this common geriatric condition has been paid in clinical settings. Emerging evidence suggests that both behavioral (nutrition and physical activity) and pharmacologic interventions may be effective in the treatment and prevention of the frailty syndrome. The papers in this book address our current understanding of the biological basis, clinical presentation and therapeutic interventions that target frailty. They highlight the transitional nature of research on the frailty syndrome and identified key unmet needs and areas for future investigation in this expanding field.

Available in PDF, EPUB and Kindle. Book excerpt: As aging trends in the United States and Europe in particular are strongly suggestive of increasingly older society, it would be prudent for health care providers to better prepare for such changes. By including physiology, disease, nutrition, pharmacology, pathology, radiology and other relevant associated topics, Geriatric Gastroenterology fills the void in the literature for a volume devoted specifically to gastrointestinal illness in the elderly. This unique volume includes provision of training for current and future generations of physicians to deal with the health problems of older adults. It will also serve as a comprehensive guide to practicing physicians for ease of reference. Relevant to the geriatric age group, the volume covers epidemiology, physiology of aging, gastrointestinal physiology, pharmacology, radiology, pathology, motility disorders, luminal disorders, hepato-biliary disease, systemic manifestations, neoplastic disorders, gastrointestinal bleeding, cancer and medication related interactions and adverse events, all extremely common in older adults; these are often hard to evaluate and judge, especially considering the complex aging physiology. All have become important components of modern medicine. Special emphasis is be given to nutrition and related disorders. Capsule endoscopy and its utility in the geriatric population is also covered. Presented in simple, easy to read style, the volume includes numerous tables, figures and key points enabling ease of understanding. Chapters on imaging and pathology are profusely illustrated. All chapters are written by specialists and include up to date scientific information. Geriatric Gastroenterology is of great utility to residents in internal medicine, fellows in gastroenterology and geriatric medicine as well as gastroenterologists, geriatricians and practicing physicians including primary care physicians caring for older adults.
Download or read book Epigenetics of Aging written by Trygve O. Tollefsbol and published by Springer Science & Business Media. This book was released on 2009-11-11 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: “A fascinating look at how scientists are working to help doctors treat the aging process itself, helping us all to lead longer, healthier lives.” —Sanjay Gupta, MD Aging—not cancer, not heart disease—is the underlying cause of most human death and suffering. The same cascade of biological changes that renders us wrinkled and gray also opens the door to dementia and disease. We work furiously to conquer each individual disease, but we never think to ask: Is aging itself necessary? Nature tells us it is not: there are tortoises and salamanders who are spry into old age and whose risk of dying is the same no matter how old they are, a phenomenon known as “biological immortality.” In Ageless, Andrew Steelecharts the astounding progress science has made in recent years to secure the same for humans: to help us become old without getting frail, to live longer without ill health or disease.
