This book was released on 2012-12-06 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cancer has become the most critical health problem in the United States. It is expected that 25% of the people will develop this dread disease, and many of these will die from the malady. The causes of cancer are varied, but the best estimate available is that 70--90% arise from environmental factors. These statistics have triggered widespread governmental action along two lines: (l) An effort to identify those chemicals and conditions that give rise to malignant processes has been mounted by the Carcino genesis Testing Program, the National Cancer Program, and subse quently, the National Toxicology Program. (2) Regulatory laws have been enacted that are administered by agencies such as TSCA, FIFRA, EPA, FDA, OSHA, and so on, whose mission is to minimize public ex posure to carcinogens. Since direct verification that specific chemicals induce cancer in hu of unanticipated expo mans is necessarily limited to known incidences sure and is therefore rare, most chemicals are identified as carcinogens only by laboratory experiments. At present, the only accepted procedure is long-term animal bioassay, and not only are these studies expensive and time-consuming, but current worldwide resources permit the evalua tion of only 300-400 chemicals per year, a miniscule amount compared to what is available in the commercial world: 30,000 existing chemicals, with approximately 700 new such materials being introduced every year.

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.

Available in PDF, EPUB and Kindle. Book excerpt: As editor I want especially to thank Dr. Ernst Freese for helpful co operation in preparing these volumes, and to express my appreclatlOn to Drs. Kurt Hirschhorn and Marvin Legator, the other members of the editorial board. Alexander Hollaender January 1971 Preface The purpose of these volumes is to encourage the development and ap plication of testing and monitoring procedures to avert significant human exposure to mutagenic agents. The need for protection against exposure to possibly mutagenic chemicals is only now coming to be generally realized. The recently issued Report of the Secretary's Commission on Pesticides and Their Possible Effects on Health (the Mrak Report-U.S. Department of Health, Education and Welfare, December 1969) has made an important start. Its Panel on Mutagenicity recommends that all currently used pesticides be tested for mutagenicity in several recently developed and relatively simple systems. Whether recommendations such as these are actually put into effect will depend on convincing government, industry, and the public that the problem is important, that the proposed tests would be effective, and that they can be conducted at a cost that is not prohibitive. Why is it important to screen environmental agents for mutagenic activity? To those who will read this book, the answer is self-evident. The sine qua non of all that we value and all that we are is our genetic heritage.
Download or read book Handbook of Mutagenicity Test Procedures written by B.J. Kilbey and published by Elsevier. This book was released on 2012-12-02 with total page 876 pages. Available in PDF, EPUB and Kindle. Book excerpt: The compilation of this book was prompted by the necessity of a bench volume which could provide the necessary background information on materials, experimental design, pitfalls and dificulties, in order to perform a particular test in an acceptable way with a minimal need for additional expert help. This Second Edition updates this information, providing: - a comprehensive bench guide - methods known to be reliable - a broad spectrum of approaches - tips to avoid pitfalls when using unfamiliar techniques - data from population records - safety aspects of mutagens and carcinogens - basic statistical concepts for experiment design This `on the bench' methodological text provides the necessary information for most of the common assays for genetic damage in use. The book includes methods which have been sufficiently used and tested to make their use reliable, but also presents methods which are not widely used at present, but which might prove most useful in screening for mutagenic effects.
Download or read book Mechanisms of Environmental Mutagenesis Carcinogenesis written by A. Kappas and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 19th annual meeting of the European Environmental Mutagen Society was held in Rhodes, Greece, from October 21st to 26th, 1989. The programme was chosen to explore what is currently known about the mechanisms of mutagenesis and carcinogenesis, induced by environmental agents, and the questions regarding the relationship of these two processes. Recent findings, techniques and methodologies in the area of biomonitoring of humans exposed to environmental mutagens-carcinogens were presented and considerable attention was also paid to the aspects and issues of collaborative environmental policy. Researchers from allover the world contributed to the programme of the meeting with posters and oral presentations, providing a variety of new data and interesting scientific approaches. A number of outstanding scientists were invited to present the results of their work. It is only their presenta tions which are included in this book, covering the following topics: Mutations and carcinogenesis; mechanisms of chemical ly-induced genetic effects on molecular, chromosomal and cell division level; adaptability and repair mechanisms; chemical carcinogenesis and oncogenes; structure and metabolism of mutagens-carcinogens; biomonitoring and epidemiology of humans exposed to environmental mutagens-carcinogens. For the sake of evaluating and controlling the mutagenic and carcinogenic potential of our environment it is indispens able to understand the mechanisms and processes by which chemicals act on the genetic material, causing either heredi tary disease or cancer. The pUblication of these proceedings will hopefully contribute to this task.
Download or read book Basic and Applied Mutagenesis written by A. Muhammed and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of the editors of this volume is to use basic and ap plied studies in the field of mutagenesis to approach a problem of especial concern. The problem is that of the usage of toxic chemi cals, particularly agricultural chemicals, in ever-increasing quan tities in those parts of the world that feed the most people. Agri cultural chemicals that are in use in Pakistan are emphasized here. These are the same chemicals that are in use throughout the develop ing world, although the quantities of the different types that are used may vary from country to country, and from region to region within countries. A number of these chemicals can no longer be sold in Europe or in the United States, and it is often difficult to iden tify a scientific reason as to why they are sold at all. It is ironic that toxic chemicals are used as a humanitarian device to rid the world of Pestilence and Famine -- two of the Horsemen of the Apocalypse. If we do not wish poisonous chemicals to become the fifth Horseman of the Apocalypse, then we must begin now to identify and regulate the large-scale usage of toxic sub stances everywhere.
Download or read book Cancer Risk Assessment written by Ching-Hung Hsu and published by John Wiley & Sons. This book was released on 2010-12-08 with total page 727 pages. Available in PDF, EPUB and Kindle. Book excerpt: With a weight-of-the-evidence approach, cancer risk assessment indentifies hazards, determines dose-response relationships, and assesses exposure to characterize the true risk. This book focuses on the quantitative methods for conducting chemical cancer risk assessments for solvents, metals, mixtures, and nanoparticles. It links these to the basic toxicology and biology of cancer, along with the impacts on regulatory guidelines and standards. By providing insightful perspective, Cancer Risk Assessment helps researchers develop a discriminate eye when it comes to interpreting data accurately and separating relevant information from erroneous.

This book was released on 2012-12-06 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: I have been privileged to witness and participate in the great growth of knowledge on chemical carcinogenesis and mutagenesis since 1939 when I entered graduate school in biochemistry at the University of Wisconsin Madison. I immediately started to work with the carcinogenic aminoazo dyes un der the direction of Professor CARL BAUMANN. In 1942 I joined a fellow graduate student, ELIZABETH CA VERT, in marriage and we soon commenced a joyous part nership in research on chemical carcinogenesis at the McArdle Laboratory for Cancer Research in the University of Wisconsin Medical School in Madison. This collaboration lasted 45 years. I am very grateful that this volume is dedi cated to the memory of Elizabeth. The important and varied topics that are reviewed here attest to the continued growth of the fields of chemical car cinogenesis and mutagenesis, including their recent and fruitful union with viral oncology. I feel very optimistic about the application of knowledge in these fields to the eventual solution of numerous problems, including the detection and estimation of the risks to humans of environmental chemical carcinogens and re lated factors.
Download or read book Mutagens in Food written by Veikko Hayatsu and published by CRC Press. This book was released on 2018-05-04 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes many different kinds of mutagens that are detected in food, and also discusses various ways to suppress their formation and activities. The mutagens discussed include those of natural origin, those caused by human manipulation of food (e.g., cooking and adding preservatives), and those formed after food has been consumed (e.g., nitrosamines). Other topics include mutagenesis and mutagen-formation inhibitors, contemporary mutagen detection methods, the fate of ingested mutagens, and risk assessments for mutagens as human carcinogens. The book emphasizes cooked-food mutagens, especially the heterocyclic amines, because of their potential as human carcinogens. Researchers and students concerned with mutagens in food will consider this book to be valuable additions to their reference libraries.
