In this issue of Current Topics in Microbiology and Immunology the authors present a unique range of examples of the regenerative response and the role of stem cells from the amphibian to human. It seems that all roads lead to cells that have the plasticity to become something else, not only in the amphibian but also in the mammal.
Popular Science gives our readers the information and tools to improve their technology and their world. The core belief that Popular Science and our readers share: The future is going to be better, and science and technology are the driving forces that will help make it better.
Substantial progress has been made in defining genes and proteins involved in development, maintenance and regeneration of teeth and bones. This knowledge has improved strategies for diagnosing and treating mineralized tissue diseases. Existing data provide credence for these genes/proteins having roles beyond those attributed to mineralized tissues. For example, they may affect systemic metabolic activity and glucose tolerance. One example is fibroblast growth factor 23 (Fgf23), a hormone secreted by osteocytes, suppressing phosphate reabsorption into the blood stream and vitamin D synthesis in the kidney. Many other bone associated proteins, perhaps acting as endocrine factors, are reported to act at distant sites to alter metabolic activity. However, there remains substantial uncertainty as to whether bone itself functioning as an endocrine organ and/or factors secreted by bone could modulate metabolic activity. Such information should be of value toward informing clinical strategies to treat mineralized tissue and metabolic disorders.
Regenerative Biology and Medicine, Second Edition — Winner of a 2013 Highly Commended BMA Medical Book Award for Medicine — discusses the fundamentals of regenerative biology and medicine. It provides a comprehensive overview, which integrates old and new data into an ever-clearer global picture. The book is organized into three parts. Part I discusses the mechanisms and the basic biology of regeneration, while Part II deals with the strategies of regenerative medicine developed for restoring tissue, organ, and appendage structures. Part III reflects on the achievements of regenerative biology and medicine; future challenges; bioethical issues that need to be addressed; and the most prom...
Could an alien organism really survive a centuries-long trip on a meteor and remain virulent enough to attack a human being? How would a scientist know she was peering at a microbe from another planet? What's the possibility of a genetically mutated monster actually developing? In a gripping exploration of the facts behind the science fiction that has enthralled millions of X-philes, Anne Simon -- the respected virologist who comes up with the science for many intriguing episodes -- discusses telomeres, cloning, the Hayflick limit, nanotechnology, endosymbionts, lentiviruses, and other strange phenomena that have challenged the intellect and threatened the lives and sanity of America's favorite FBI agents. With Simon's extraordinary gift for explaining complicated, cutting-edge science in a light, accessible style, and her behind-the-scenes commentary on the development of various plot lines, The Real Science Behind the X-Files will appeal to science buffs and X-Files aficionados alike.
Regeneration, the homeostatic ability to maintain tissue structure in the face of normal cell turnover or loss of tissue damaged by trauma or disease, is an essential developmental process that continues throughout life. As recently as a decade ago, any serious discussion of the possibility of regeneration becoming a practical medical tool in the near future had the air of science fiction or over-optimistic speculation. The term “regenerative medicine” was certainly on many lips but few actually expected to soon see it applied in a clinical setting. A tidal wave of discovery has changed that and investigating the cellular mechanisms of natural regeneration has become one of the hottest t...
A revolution is occurring in the Western science of longevity, regeneration, and health that is elucidating the potential for extended human lifespan in an optimal state of health. This investigation is being conducted on the molecular, cellular, physiological, and psychological levels. Rigorous integrative medicine research can only be adequately developed if collaboration between scientists and practitioners from both fields is involved. This volume brings together researchers and scholars from both the Indo-Tibetan traditions and the international scientific community to open a dialogue about the potential to build a program of collaborative research to study the impact of Indo-Tibetan pr...
With ever-advancing scientific understanding and technological capabilities, humanity stands on the brink of the potential next stage of evolution: evolution engineered by us. Nanotechnology, biotechnology, information technology and cognitive science offer the possibility to enhance human performance, lengthen life-span and reshape our inherited physical, cognitive and emotional identities. But with this promise come huge risks, complex choices and fundamental ethical questions: about evolution; about what it is to be human; and about control over, and the distribution of benefits from, new technology. Written by a range of experts in science, technology, bioethics and social science, Unnatural Selection examines the range of technological innovations offering lives that purport to be longer, stronger, smarter and happier, and asks whether their introduction is likely to lead to more fulfilled individuals and a fairer world. The breadth of approaches and perspectives make important reading for anyone who cares about the implications of humanity engineering its own evolution.
Research in diabetes has accelerated in two areas, both of which are being reviewed in CTMI. The first is the use of a variety of animal models; the second is basic research in human investigation, islet cell antigens, and mapping of genes as sociated with susceptibility to disease. Dr. Thomas Dyrberg accepted editorial responsibility for this volume, which covers the first area. A second book, to be published later in the year, is edited by Drs. Brekkeskov and Hansen (CTMI 164, see page VI for contents). Although the contributors to both volumes represent the international scientific community, the editors are from the Hagedorn Research Laboratory in Denmark. Work at this institute and the ...
This volume provides a transdisciplinary and translational review of many of the leading murine models used to study the mechanisms, mediators and biomarkers linking energy balance to cancer. It provides a review of murine models that should be of interest to basic, clinical and applied research investigators as well as nutrition scientists and students that work in cancer prevention, cancer control and treatment. The worldwide obesity pandemic has been extensively studied by epidemiologic and observational studies and even, in some cases, by randomized controlled trials. However, the development and control of obesity, its comorbidities and its impact on cancer usually occurs over such long...
