Available in PDF, EPUB and Kindle. Book excerpt: During the early 1930s, when I was a graduate student and later a post-doctoral researcher at the National Research Council for the University of Wisconsin at Madison, we had the opportunity to get acquainted with many graduate students from China who were sent to the University for training in modern basic sciences as well as social sciences. The University of Wisconsin continues to graduate a large number of Chinese students. Economic conditions in the 1930s were very precarious for the United States and other parts of the world. Many of us students grew closer together because we were living on similarly tight budgets. As a matter of fact, we subleased a part of our apartment in Madison to some Chinese graduate students. This was a very nice opportunity for us to learn about the scientific and cultural back ground of our Chinese friends. Many of them came from the interior of China and had had very little opportunity to become acquainted with people from a western culture. Living with these students was a very pleasant and educational experience which gave us a good pic ture of the cultural life and educational system of China at that time--an intimate picture that one normally would not see without travelling in that country.
Download or read book Carcinogens and Anticarcinogens in the Human Diet written by National Research Council and published by National Academies Press. This book was released on 1996-03-12 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite increasing knowledge of human nutrition, the dietary contribution to cancer remains a troubling question. Carcinogens and Anticarcinogens assembles the best available information on the magnitude of potential cancer riskâ€"and potential anticarcinogenic effectâ€"from naturally occurring chemicals compared with risk from synthetic chemical constituents. The committee draws important conclusions about diet and cancer, including the carcinogenic role of excess calories and fat, the anticarcinogenic benefit of fiber and other substances, and the impact of food additive regulation. The book offers recommendations for epidemiological and diet research. Carcinogens and Anticarcinogens provides a readable overview of issues and addresses critical questions: Does diet contribute to an appreciable proportion of human cancer? Are there significant interactions between carcinogens and anticarcinogens in the diet? The volume discusses the mechanisms of carcinogenic and anticarcinogenic properties and considers whether techniques used to evaluate the carcinogenic potential of synthetics can be used with naturally occurring chemicals. The committee provides criteria for prioritizing the vast number of substances that need to be tested. Carcinogens and Anticarcinogens clarifies the issues and sets the direction for further investigations into diet and cancer. This volume will be of interest to anyone involved in food and health issues: policymakers, regulators, researchers, nutrition professionals, and health advocates.
Download or read book Issues in Risk Assessment written by National Research Council and published by National Academies Press. This book was released on 1993-02-01 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: The scientific basis, inference assumptions, regulatory uses, and research needs in risk assessment are considered in this two-part volume. The first part, Use of Maximum Tolerated Dose in Animal Bioassays for Carcinogenicity, focuses on whether the maximum tolerated dose should continue to be used in carcinogenesis bioassays. The committee considers several options for modifying current bioassay procedures. The second part, Two-Stage Models of Carcinogenesis, stems from efforts to identify improved means of cancer risk assessment that have resulted in the development of a mathematical dose-response model based on a paradigm for the biologic phenomena thought to be associated with carcinogenesis.

Readers will also benefit from the inclusion of: A thorough introduction to the development of regulatory guidelines for mutagenic and genotoxic impurities, including a historical perspective on the development of the EMEA guidelines and the ICH M7 guideline An exploration of in silico assessment of mutagenicity, including use of structure activity relationship evaluation as a tool in the evaluation of the genotoxic potential of impurities A discussion of a toxicological perspective on mutagenic impurities, including the assessment of mutagenicity and examining the mutagenic and carcinogenic potential of common synthetic reagents Perfect for chemists, analysts, and regulatory professionals, Mutagenic Impurities: Strategies for Identification and Control will also earn a place in the libraries of toxicologists and clinical safety scientists seeking a one-stop reference on the subject of mutagenic impurity identification and control.
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 Chemical Carcinogenesis written by Claudio Nicolini and published by Springer. This book was released on 2012-11-25 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: During October 18-30, 1981, the second course of the International School of Pure and Applied Biostructure, a NATO Advanced Study Institute, was held at the Ettore Majorana Center for Scientific Culture in Erice, Italy, co-sponsored by the International Union Against Cancer, the Italian League Against Cancer, the Italian Ministry of Public Education, the Italian Ministry of Scientific and Technological Research, the North Atlantic Treaty Organization, the Italian National Research Council, the Sicilian Regional Government and two pharmaceutical Companies (Zambeletti and Farmitalia). The subject of the course was "Chemical Carcino genesis" with participants selected world-wide from 18 different countries. It is now eminently clear that.the bulk of human cancers are related to one of several types of environmental exposure. Of the environmental hazards, chemicals are among the best characterized carcinogens. However, how chemicals induce cancer is still poorly understood. Because of the magnitude of the problem and the ob vious need for a much more critical scientific analysis of the process by which cancer is induced (carcinogenesis), it was highly desirable to expose a greater number of scientists with varying background to some of the latest thinking in chemical carcino genesis. The course had this as its major objective and the re sulting book does reflect it.
Download or read book Veterans at Risk written by Institute of Medicine and published by National Academies Press. This book was released on 1993-02-01 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recently, World War II veterans have come forward to claim compensation for health effects they say were caused by their participation in chemical warfare experiments. In response, the Veterans Administration asked the Institute of Medicine to study the issue. Based on a literature review and personal testimony from more than 250 affected veterans, this new volume discusses in detail the development and chemistry of mustard agents and Lewisite followed by interesting and informative discussions about these substances and their possible connection to a range of health problems, from cancer to reproductive disorders. The volume also offers an often chilling historical examination of the use of volunteers in chemical warfare experiments by the U.S. militaryâ€"what the then-young soldiers were told prior to the experiments, how they were "encouraged" to remain in the program, and how they were treated afterward. This comprehensive and controversial book will be of importance to policymakers and legislators, military and civilian planners, officials at the Department of Veterans Affairs, military historians, and researchers.

In Human behavior, including stress and other factors, plays an important role in neoplasia, although too little is known addition, variables which affect cancer development as well on the reasons for such development. Carcinogens, which as some endogenous factors can be better delineated help initiate the neoplastic process, may be either synthetic through such investigations. The topics of this volume encompass premalignant non or naturally-occurring. Cancer causation may be ascribed to invasive lesions, species-specific aspects of carcinogenicity, certain chemicals, physical agents, radioactive materials, viruses, parasites, the genetic make-up of the organism, and radiation, viruses, a quantum theory of carinogenesis, onco bacteria. Humans, eumetazoan animals and vascular plants genes, and selected environmental carcinogens. are susceptible to the first six groups of cancer causes, whe reas the last group, bacteria, seems to affect only vascular plants. Neoplastic development may begin with impairment ofJmdy defenses by a toxic material (carcinogen) which acts as an initiator, followed by promotion and progression to an overt neoplastic state. Investigation of these processes Series Editor Volume Editor allows not only a better insight into the mechanism of action Hans E. Kaiser Elizabeth K. Weisburger vii ACKNOWLEDGEMENT Inspiration and encouragement for this wide ranging project on cancer distribution and dissemination from a comparative biological and clinical point of view, was given by my late friend E.

Available in PDF, EPUB and Kindle. Book excerpt: Topics in Toxicology Toxicology is a science that stands at the intersection of several interests and disciplines. These intersecting forces are by no means all scientific since some are legal and some are commercial. All have valid things to say about the conduct and interpretation of toxicity experiments. The practising toxicologist must bear all these sometimes conflicting forces in mind as he carries out his duties. This is especially true, of course, of the toxicologist in industry. Toxicology is also a field in which contract research particularly flourishes and a number of major contract research companies have established over the years a reputation for contributing usefully to the practice of this skill. These contract research organisations are particu larly favoured to develop an appreciation of the problems of the industrial toxicologist, since it is very common for such a company to service the toxicological needs of companies in several sectors of industry producing new chemical compounds, and the contract research company, therefore, is aware of a wider diversity of problems than probably affects a single toxicologist in one industry.
