Download or read book Accuracy in Molecular Processes written by Thomas Kirkwood and published by Springer. This book was released on 1986-06-19 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: Molecular biology proceeds at unremitting pace to unfold new secrets of the living world. Biology, long regarded as an inexact companion to physics and chemistry, has undergone transformation. Now, chemical and physical principles are tools in understanding highly complex biomolecular processes, whose origin lies in a history of chance, constraint and natural selection. The accuracy of these processes, often remarkably high, is crucial to their self perpetuation, both individually and collectively, as ingredients of the organism as a whole. In this book are presented thirteen chapters which deal with various facets of the accuracy problem. Subjects covered include: the specificity of enzymes; the fidelity of synthesis of proteins; the replication and repair of DNA: general schemes for the enhancement of biological accuracy; selection for an optimal balance between the costs and benefits of accuracy; and the possible relevance of molecular mistakes to the process of ageing. The viewpoints are distinct, yet complementary, and the book as a whole offers to researchers and students the first comprehensive account of this growing field.
Download or read book Recoding Expansion of Decoding Rules Enriches Gene Expression written by John F. Atkins and published by Springer Science & Business Media. This book was released on 2010-03-10 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: The literature on recoding is scattered, so this superb book ?lls a need by prov- ing up-to-date, comprehensive, authoritative reviews of the many kinds of recoding phenomena. Between 1961 and 1966 my colleagues and I deciphered the genetic code in Escherichia coli and showed that the genetic code is the same in E. coli, Xenopus laevis, and guinea pig tissues. These results showed that the code has been c- served during evolution and strongly suggested that the code appeared very early during biological evolution, that all forms of life on earth descended from a c- mon ancestor, and thus that all forms of life on this planet are related to one another. The problem of biological time was solved by encoding information in DNA and retrieving the information for each new generation, for it is easier to make a new organism than it is to repair an aging, malfunctioning one. Subsequently, small modi?cations of the standard genetic code were found in certain organisms and in mitochondria. Mitochondrial DNA only encodes about 10–13 proteins, so some modi?cations of the genetic code are tolerated that pr- ably would be lethal if applied to the thousands of kinds of proteins encoded by genomic DNA.
Download or read book Encyclopedia of Aging and Public Health written by Sana Loue and published by Springer Science & Business Media. This book was released on 2008-01-16 with total page 852 pages. Available in PDF, EPUB and Kindle. Book excerpt: Americans are living longer, and the elder population is growing larger. To meet the ongoing need for quality information on elder health, the Encyclopedia of Aging and Public Health combines multiple perspectives to offer readers a more accurate and complete picture of the aging process. The book takes a biopsychosocial approach to the complexities of its subject. In-depth introductory chapters include coverage on a historical and demographic overview of aging in America, a guide to biological changes accompanying aging, an analysis of the diversity of the U.S. elder population, legal issues commonly affecting older adults, and the ethics of using cognitively impaired elders in research. From there, over 425 entries cover the gamut of topics, trends, diseases, and phenomena: -Specific populations, including ethnic minorities, custodial grandparents, and centenarians -Core medical conditions associated with aging, from cardiac and pulmonary diseases to Parkinson’s and Alzheimer’s -Mental and emotional disorders -Drugs/vitamins/alternative medicine -Disorders of the eyes, feet, and skin -Insomnia and sleep disorders; malnutrition and eating disorders -Sexual and gender-related concerns -And a broad array of social and political issues, including access to care, abuse/neglect, veterans’ affairs, and assisted suicide Entries on not-quite-elders’ concerns (e.g., midlife crisis, menopause) are featured as well. And all chapters and entries include references and resource lists. The Encyclopedia has been developed for maximum utility to clinicians, social workers, researchers, and public health professionals working with older adults. Its multidisciplinary coverage and scope of topics make this volume an invaluable reference for academic and public libraries.
Download or read book Insect Aging written by Klaus-Günter Collatz and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Leben ist die schonste Erfindung der Natur und der Tod ist ihr Kunstgriff, viel Leben zu haben" . J. W. v. Goethe Life is the most beautiful invention of nature, and death is her device to exhibit most life. The eminent British biologist Sir Vincent B. Wigglesworth noted in 1939 that insects are an ideal medium in which to study all problems of physiology. Many fundamental discoveries in biology, particularly genetics and development, have been made on the basis of studies conducted in insects. Because of their ex treme adaptability and diversity, an appropriate insect model is available for the study of virtually any biological problems. The applicability to other groups, including mammals, of basic studies conducted on insects has helped in the gradual acceptance of the fundamental unity of biochemical principles as a dogma among biologists, as well as among enlightened medical scientists. With the recent upsurge of interest in the study of the aging process, in sects have been increasingly employed not only for the investigation of basic mechanisms of aging, but also to gain insight into the evolution of aging and senescence. If only one aging mechanism exists, it is foreseeable that some in sects, especially Drosophila, will help to unravel its molecular basis. Because of their diversity, existing studies in the gerontology of insects are widely scat tered in various specialized journals. This wealth of existing information has not, as yet, been brought together in a synthesized and comprehensive form.
Download or read book The Logic of Chance written by Eugene V. Koonin and published by FT Press. This book was released on 2011-06-23 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Logic of Chance offers a reappraisal and a new synthesis of theories, concepts, and hypotheses on the key aspects of the evolution of life on earth in light of comparative genomics and systems biology. The author presents many specific examples from systems and comparative genomic analysis to begin to build a new, much more detailed, complex, and realistic picture of evolution. The book examines a broad range of topics in evolutionary biology including the inadequacy of natural selection and adaptation as the only or even the main mode of evolution; the key role of horizontal gene transfer in evolution and the consequent overhaul of the Tree of Life concept; the central, underappreciated evolutionary importance of viruses; the origin of eukaryotes as a result of endosymbiosis; the concomitant origin of cells and viruses on the primordial earth; universal dependences between genomic and molecular-phenomic variables; and the evolving landscape of constraints that shape the evolution of genomes and molecular phenomes. "Koonin's account of viral and pre-eukaryotic evolution is undoubtedly up-to-date. His "mega views" of evolution (given what was said above) and his cosmological musings, on the other hand, are interesting reading."

Download or read book Aging at the Molecular Level written by Thomas von Zglinicki and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last 40 years, the study of the biological basis of aging has progressed tremendously, and it has now become an independent and respectable field of study and research. The essential cause of aging is molecular damage that slowly overwhelms cellular and organismic defense, repair and maintenance systems. In recent years, a wealth of highly sophisticated research has transformed this idea from a credible hypothesis not only to a major theory, but essentially to accepted knowledge. Aging at the Molecular Level examines the key elements in this transformation. Bringing together contributions from an international team of authors, this volume will be of interest to graduates and postgraduates in the fields of medicine and nursing, researchers of different aspects of biogerontology and those in the pharmaceutical, cosmeceutical, nutraceutical and health-care industry.

Download or read book Understanding Ageing written by Robin Holliday and published by Cambridge University Press. This book was released on 1995-01-27 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a completely novel approach to the understanding of ageing, which many believe is an unsolved problem in biology. It explains why ageing exists in animals, and reviews our understanding of it at the biological level. This includes a discussion of the origins and evolution of ageing. The book is not a review of research on ageing, but instead draws on material from a wide range of disciplines, including the very extensive biomedical information about age-related diseases in humans. Understanding Ageing argues that much research needs to be done on the cellular and molecular aspects of ageing, if the origins of these diseases are to be understood, and their prevention made possible. This thought-provoking book will appeal to all students and researchers who are interested in ageing, whether they are working in the clinical or basic research sphere.
