This book was released on 2012-12-06 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is concerned with the genetic consequences of nu cleotide pool imbalance. There are a number of ways in which this state can be achieved and the majority of papers in this volume de scribe the effects of nucleotide pool imbalance on DNA replication and repair, and the induction of gene mutations in various organisms. This book grew out of a Conference on "Genetic Consequences of Nu cleotide Pool Imbalance" which was held at the National Institute of Environmental Health Sciences on May 9-11, 1983. The Organizing Com mittee consisted of Drs. Diana Anderson (BIBRA), Robert Haynes (York University), Bernard Kunz (NIEHS), Barry Glickman (NIEHS), and Frederick J. de Serres (NIEHS), Chairman. The meeting was org- ized by the staff of the Office of the Associate Director for Genetics and was financed solely by the National Institute of Environmental Health Sciences.

Available in PDF, EPUB and Kindle. Book excerpt: Heritable human genome editing - making changes to the genetic material of eggs, sperm, or any cells that lead to their development, including the cells of early embryos, and establishing a pregnancy - raises not only scientific and medical considerations but also a host of ethical, moral, and societal issues. Human embryos whose genomes have been edited should not be used to create a pregnancy until it is established that precise genomic changes can be made reliably and without introducing undesired changes - criteria that have not yet been met, says Heritable Human Genome Editing. From an international commission of the U.S. National Academy of Medicine, U.S. National Academy of Sciences, and the U.K.'s Royal Society, the report considers potential benefits, harms, and uncertainties associated with genome editing technologies and defines a translational pathway from rigorous preclinical research to initial clinical uses, should a country decide to permit such uses. The report specifies stringent preclinical and clinical requirements for establishing safety and efficacy, and for undertaking long-term monitoring of outcomes. Extensive national and international dialogue is needed before any country decides whether to permit clinical use of this technology, according to the report, which identifies essential elements of national and international scientific governance and oversight.

Book excerpt: The finding that chemicals can be metabolically activated to yield reactive chemical species capable of covalently binding to cellular macromolecules and the concept that these reactions could initiate toxicological and carcinogenic events stimulated a meeting by a small group of toxicologists at the University of Turku, in Finland, in 1975 (Jollow et al. , 1977). The growing interest in this field of research led to subsequent symposia at the University of Surrey, in England in 1980 (Snyder et al. , 1982), and the University of Maryland in the U. S. A. in 1985 (Kocsis et al. , 1986). The Fourth International Symposium on Biological Reactive Intermediates was hosted by the Center for Toxicology at the University of Arizona and convened in Tucson, Arizona, January 14-17, 1990. Over 300 people attended. There were 60 platform presentations by invited speakers, and 96 volunteer communications in the form of posters were offered. These meetings have grown from a small group of scientists working in closely related areas to a major international series of symposia which convene every five years to review, and place in context, the latest advances in our understanding of the formation, fate and consequences of biological reactive intermediates. The Organizing Committee: Allan H. Conney, Robert Snyder (Co-chairman), and Charlotte M. Witmer (Rutgers University, Piscataway, NJ), David J. Jollow Co chairman) (Medical University, South Carolina, Charleston, SC), 1. Glenn Sipes (Co chairman) (University of Arizona, Tucson, AZ), James J. Kocsis and George F.

This book was released on 2013-11-21 with total page 531 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present workshop had its orlglns in discussions among Alexander Hollaender, Oddvar Nygaard, Donald Borg, Richard Setlow and Victor Bond on the need for a symposium that would deal with a broad spectrum of pressing subjects related to the physics, chemistry, and biological actions of ionizing radiations, and the theoretical and practical problems of risk assessment. It soon became apparent that the spectrum of subjects considered was too broad for the desired depth of coverage; in fact, it seemed un likely that the conference participants would have the background knowledge to span the gamut. Therefore, two separate meetings were decided upon, the first of which, Comparison of Mechanisms of Carcinogenesis by Radiation and Chemical Agents, was held at the National Bureau of Standards, Gaithersburg on December 6-7, 1983. The meeting was sponsored by the NCI. The second meeting has emerged as the present workshop at Brookhaven National Laboratory. An interface between the two conferences has been provided by Michael Fry and Donald Borg, who have summarized the salient points emanating from the NCI Symposium. We intended that the first conference should focus on the basic mechanisms of radiation and chemical carcinogenesis, while the second, the present meeting, would emphasize exposure-response relationships, particularly the theoretical and practical similar ities and differences between exposure to chemical carcinogens compared to exposure to ionizing radiation.

Available in PDF, EPUB and Kindle. Book excerpt: Are infectious diseases caused by novel entities, viruses that have rapidly evolved into more pathogenic forms, or viruses that have crossed species divides and become more virulent in their alternative host? These questions and how new diseases such as AIDS emerged have prompted renewed interest in the ways viruses originated and co-evolved with their hosts. Origin and Evolution of Viruses presents a full and clear description of general viral concepts and specific viral systems, and provides an excellent foundation to our understanding of how viruses emerged. This unique and comprehensive work is essential reading for all researchers in virology, molecular biology and related areas, as well as evolutionary biologists interested in phylogenetic approaches to molecular evolution. The reader is taken on an illumination journey--in time and concepts--from the first primitive replicons to their present-day complex viral counterparts. Apart from the obvious interest, as humans are potential hosts for these viruses, there is also a great deal of academic interest in the evolutionary aspects of this simple group of organisms, since information can be gained about the origin of stains/species and evolutionary patterns that might be applicable to higher species. The book addresses: * Nature and evolution of early replicons * DNA and RNA viruses in both plants and animals * Viral origin, mutation, and survival * Antigenic variation in influenza virus * Interplay between host evolution and DNA virus evolution * Emergence of viral-induced diseases, e.g. hepatitis, influenza and HIV

Book excerpt: For more than 50 years, it has been recognized that diet influences cancer formation both in humans and in experimental animals. In fact, early investigators successfully retarded the onset of tumors in animals by dietary manipulation. Such findings led to an early optimism that cancer would prove to be yet another disease resulting from dietary imbalances and might thus be amenable to prevention or cure by appropriate nutritional changes. Subsequent studies showed that the influence of diet on cancer formation was not only very complex, it also did not appear to playa direct causative role in carcinogenesis. Thus during the mid-1950s scientific interest in diet and cancer greatly waned. By the early 1970s, however, a resurging interest in diet and cancer became evident. This field of activity has continued to grow. Yet for over 20 years, no comprehensive meeting has been held to summarize the major developments concerning dietary modification of carcinogenesis over a broad range of essential nutrients. To fill this void, a workshop was held on the role of essential nutrients in carcinogenesis from January 30 to February 1, 1985, in Bethesda, Maryland, under the auspices of the National Cancer Institute. This volume is a compilation of the presenta tions made at that meeting.

Book excerpt: Microcompartmentation refers to nonhomogeneous distribution of solutes in compartments of cells or associated structures without intervening membranal barriers. Such variations in concentration of ions, metabolites, intracellular messengers, and nutrients can introduce significant heterogeneity in subcellular function and regulation. The current focus on biological examples of microcompartmentation provides ample evidence for its importance and the role of physical structure in determining local chemical environments. The examples present in the different chapters include microcompartmentation of Ca2+,H+,ATP. ADP, O2, glycolytic intermediates, fatty acids, amino acids, and nucleic acid precursors. In reviewing these systems, the authors provide a useful resource for experimental approaches to study microcompartmentation and provide the basis for future studies of its role in regulation of cell functions.

Available in PDF, EPUB and Kindle. Book excerpt: This collection of review articles authored by international experts pulls together current information about the role of mitochondria in aging and diseases of aging. Mitochondria are vitally important cellular organelles and undergo their own aging process becoming less efficient in aged animals including humans. These changes have wide-ranging significance contributing to immune dysfunction (autoimmunity and immune deficiency), inflammation, delayed healing, skin and retinal damage, cancer and most of the degenerative diseases of aging. Mitochondrial aging predisposes to drug toxicity in the geriatric population and to many of the features of normal aging. The research detailed in this book summarizes current understanding of the role of mitochondria in the complex molecular changes of aging, moving on to specific diseases of aging. Mitochondrial dysfunction is an important target for development of treatments for aging and disease. The last article details how exercise is a treatment and combats many features of the aging process.

Available in PDF, EPUB and Kindle. Book excerpt: These original contributions by symbiosis biologists and evolutionary theorists address the adequacy of the prevailing neo-Darwinian concept of evolution in the light of growing evidence that hereditary symbiosis, supplemented by the gradual accumulation of heritable mutation, results in the origin of new species and morphological novelty.A departure from mainstream biology, the idea of symbiosis--as in the genetic and metabolic interactions of the bacterial communities that became the earliest eukaryotes and eventually evolved into plants and animals--has attracted the attention of a growing number of scientists.These original contributions by symbiosis biologists and evolutionary theorists address the adequacy of the prevailing neo-Darwinian concept of evolution in the light of growing evidence that hereditary symbiosis, supplemented by the gradual accumulation of heritable mutation, results in the origin of new species and morphological novelty. They include reports of current research on the evolutionary consequences of symbiosis, the protracted physical association between organisms of different species. Among the issues considered are individuality and evolution, microbial symbioses, animal-bacterial symbioses, and the importance of symbiosis in cell evolution, ecology, and morphogenesis. Lynn Margulis, Distinguished Professor of Botany at the University of Massachusetts at Amherst, is the modern originator of the symbiotic theory of cell evolution. Once considered heresy, her ideas are now part of the microbiological revolution. ContributorsPeter Atsatt, Richard C. Back, David Bermudes, Paola Bonfante-Fasolo, René Fester, Lynda J.

Book excerpt: This book is based on the papers presented at the conference on "Mecha nisms of DNA Damage and Repair: Implications for Carcinogenesis and Risk Assessment," held at the National Bureau of Standards on June 2-7, 1985, This volume deals with mechanisms of DNA damage and repair at the molecular level; consequences of unrepaired or misrepaired damage, with major emphasis on carcinogenesis; drugs which bind selectively to altered and potentially damaging DNA sequences; and potential utilization of DNA damage as an endpoint for assessing risks of UV light, ionizing radiations, chemicals, drugs, and hazardous agents in foods. Because the induction of mutations by radiation and genotoxic chemicals has been observed to follow one-hit kinetics in some instances, it is generally assumed that any level of exposure to a DNA-damaging agent may increase the risk of genetic disease or cancer in an exposed population. At the same time, however, there is evidence that although the DNA of living cells is continually damaged by natural background radiation, free radicals, and other naturally occurring processes, most of the damage is normally repaired.
