Download or read book Micronucleus Assay in Toxicology written by Siegfried Knasmueller and published by Royal Society of Chemistry. This book was released on 2019-07-18 with total page 536 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concerns about the adverse health effects of chemicals and radiation present in the environment and at workplaces have created the need for better detection systems to assess their potential to cause DNA damage in humans and other organisms across ecosystems. The Micronucleus Assay in Toxicology is the first comprehensive volume concerning the use of micronucleus assays in genetic toxicology. It succinctly explains the mechanisms by which genotoxins cause micronucleus formation and its relation to diseases. Furthermore, it describes the methods which are currently used for the analyses of micronuclei in different types of cells in human in vivo biomonitoring studies, routine in vivo tests with rodents, in vitro studies with human and mammalian cells, environmental monitoring with invertebrates and vertebrates such as molluscs, fish and, also, in plant bioassays. Moreover, this book also focuses on the use of the micronucleus technique in other research areas, including the detection of DNA damage caused by important groups of genotoxic carcinogens (heavy metals, industrial chemicals, cytotoxic drugs, pesticides, ionising radiation, etc.) as well as study designs, statistical analyses, international regulatory guidelines, and the development of automated scoring devices for this assay. This book will serve as both, a reference and a guide to students, and investigators in biomedical, biochemical and pharmaceutical sciences interested in gaining a better understanding of the biology of micronuclei and their application in measuring DNA damage caused by natural or man-made genotoxins.
Download or read book Biomarkers and Human Biomonitoring written by Lisbeth Knudsen and published by Royal Society of Chemistry. This book was released on 2011-10-19 with total page 499 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human biomonitoring has developed from a research tool in occupational and environmental health to identify and quantify exposures to harmful substances in urine and blood. The analytical methods for detection of substances in biological media have considerably improved with smaller detection limits and more precise and specific measurements. Human biomonitoring is a valuable tool in exposure estimation of selected populations and currently used in surveillance programs all over the world. This two volume set provides an overview of current available biomarkers and human biomonitoring programs in environmental health, which is timely given the present debate on adverse health effects from environmental exposures. The books decribe both previous and ongoing studies as well as the newer biomarkers of exposure and effects. Volume one describes current human biomonitoring programs in Germany, Romania, France, Canada, India and Belgium, providing convincing evidence of a global decline in human exposures to lead and increasing concern from exposure to endocrine disruptors and the genotoxic compound. Biomarkers of specific exposures to a wide range of widely used everyday compounds such as phthalates, PFCs, bisphenol A, brominated flame retardants, PAHs, dioxins, mercury and arsenic are also discussed. Volume two decribes human biomonitoing of exposures to environmental tobacco smoke, mycotoxins, physiological stress, hormone activity, oxidative stress and ionizing radiation, as well as effect biomarkers of hemoglobin adducts, germ cells, micronuclei and individual susceptability. The books will be essential reading for toxicologists, environmental scientists and all those working in the safety and risk assessment of chemicals.
Download or read book Biological Dosimetry written by W. G. Eisert and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: In October 1982, a small international symposium was held at the Gesellschaft fUr Strahlen- und Umweltforschung mbH (GSF) in Munich as a satellite meeting of the IX International Conference on Analytical Cytology. The symposium focussed on cytometric approaches to biological dosimetry, and was, to the best of our knowledge, the first meeting on this subject ever held. There was strong encouragement from the 75 attendees and from others to publish a proceedings of the symposium. Hence this book, containing 30 of the 36 presentations, has been assembled. Dosimetry, the accurate and systematic determination of doses, usually refers to grams of substance administered or rads of ionization or some such measure of exposure of a patient, a victim or an experimental system. The term also can be used to describe the quantity of an ultimate, active agent as delivered to the appropriate target material within a biological system. Thus, for mutagens, one can speak of DNA dosimetry, meaning the number of adducts produced in the DNA of target cells such as bone-mar row stem cells or spermatogonia.
Download or read book Regulatory Toxicology written by Franz-Xaver Reichl and published by Springer. This book was released on 2014-03-27 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book will be written by experts for professionals, scientists and all those involved in toxicological data generation and decision-making. It is the updated and expanded version of a monograph published in German in 2004. Chemical safety is regulated on various levels including production, storage, transport, handling, disposal or labelling. This book deals comprehensively with the safety-ensuring methods and concepts employed by regulatory agencies, industry and academics. Toxicologists use experimental and scientific approaches for data collection, e.g. about chemical hazards, physicochemical features or toxicokinetics. The respective experimental methods are described in the book. Toxicologists also deal with much insecurity in the exposure and effect scenarios during risk assessment. To overcome these, they have different extrapolation methods and estimation procedures at their disposal. The book describes these methods in an accessible manner. Differing concepts from one regulation area to another are also covered. Reasons and consequences become evident when reading the book. Altogether, the book Regulatory Toxicology will serve as an excellent reference.
Download or read book Oxidative Stress Biomarkers and Antioxidant Protocols written by Donald Armstrong and published by Springer Science & Business Media. This book was released on 2008-02-04 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first protocols book, Free Radical and Antioxidant Protocols (1) was published in late 1998. Sections were divided into three parts, covering selected biochemical techniques for measuring oxidative stress, antioxidant (AOX) activity, and combined applications. In choosing the 40 methods to be included in that book, I realized there were considerably more of equal value than that which we could have presented in a single volume. To produce a comprehensive resource, this book and a third are being compiled to expand coverage of the field. A summary of papers (2) published on this important subject emphasizes the continuing rapid growth in oxidative stress investigations relating to our understanding of biochemical reactions, their relevance to pathophysiological mechanisms, how disease may arise, and how therapeutic intervention may be achieved(3). Although there is some overlap between the categories, the ana- sis shown below illustrates where current studies are concentrated and are almost evenly distributed between free radicals and AOX. Over the last 4 yr, there has been a 55% increase in the number of papers published in the area.
Download or read book Environmental Epidemiology written by Roberto Bertollini and published by CRC Press. This book was released on 1995-11-16 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental Epidemiology: Exposure and Disease is a unique resource identifying priorities for public health research in selected areas of environmental epidemiology. Drawn from the proceedings of an international workshop on this topic, the book is a compilation of the specialized knowledge and opinions of environmental epidemiology experts. Organized by the Rome division of the World Health Organization (WHO) European Centre for Environment and Health, the goal of the 1993 workshop, Setting Priorities in Environmental Epidemiology, was to establish a consensus among the experts in the selected areas. The chapters in Environmental Epidemiology: Exposure and Disease cover environmental epidemiology from three different viewpoints: environmental exposures, major disease groups related to the environment, and epidemiological methodology. The environmental exposure categories examined for prioritizing are air contaminants, water contaminants, and ionizing and non-ionizing radiation exposure from human-caused disasters. The major disease groups covered are neoplastic diseases, lung cancer, and non-carcinogenic respiratory disease. Methods discussed in the book include small area studies, use of biochemical markers, exposure assessment, and training. To prioritize, the authors utilized a set of criteria based on exposure conditions, health effects, and the feasibility of human studies. Within the complex and rapidly growing field of environmental epidemiology, this compendium of international expertise provides essential guidance for research emphasis and the allocation of financial and technical resources.
Download or read book How Tobacco Smoke Causes Disease written by United States. Public Health Service. Office of the Surgeon General and published by . This book was released on 2010 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.
Download or read book Some Organophosphate Insecticides and Herbicides written by IARC Working Group on the Evaluation of Carcinogenic Risks to Humans and published by World Health Organization. This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume of the IARC Monographs provides evaluations of the carcinogenicity of some organophosphate insecticides and herbicides, including diazinon, glyphosate, malathion, parathion, and tetrachlorvinphos. Diazinon acts on a wide range of insects on crops, gardens, livestock, and pets, but most uses have been restricted in the USA, Canada, and the European Union since the 1980s. Glyphosate is the most heavily used agricultural and residential herbicide in the world, and has been detected in soil, air, surface water, and groundwater, as well as in food. Malathion is one of the oldest and most widely used organophosphate insecticides, and has a broad spectrum of applications in agriculture and public health, notably mosquito control. The insecticide parathion has been largely banned or restricted throughout the world due to toxicity to wildlife and humans. Tetrachlorvinphos is banned in the European Union, but continues to be used in the USA and elsewhere as an insecticide on animals, including in pet flea collars. The IARC Monographs Working Group reviewed epidemiological evidence, animal bioassays, and mechanistic and other relevant data to reach conclusions as to the carcinogenic hazard to humans of these agents.
