Book Description
To meet the needs of an ever-growing world population for food and fiber, agriculture uses an arsenal of chemicals to control insects, weeds and other pests that compete with man in the agricultural arena. In addition to their intended effect, many of these biologically active materials affect non-target organisms including man himself. There is concern about the resulting occupational exposure of those who work in agriculture and the environmental health of those who live in rural areas. Unintended side effects from the use of agricultural chemicals are further complicated by the dispersal of these substances well beyond the area of immediate use, through food chains, atmospheric transport, irrigation runoff, percolation to and diffusion through ground water, sometimes giving rise to public health and environmental problems at a distance from the place of application. In addition to toxic substances introduced into the agro ecosystem by man, one must be concerned about naturally occurring agents including mfcotoxins, plant poisons, infective biological agents and the levels of certain heavy metals. The formation of toxic substances, many of them mutagenic, during cooking and other processing of food is a related problem. While acute effects are more immediate and somewhat readily discerned, chronic and genetic effects tend to be more obscure and sometimes surface in a crisis situation long after substantial damage has been sustained. Genotoxicity assays and epidemiological studies play increasing roles in predicting and evaluating long term effects of low-level exposure to toxic materials.

Book Description
Genetic Toxicology is a comprehensive book covering the historical perspective of genetic toxicology; basic mechanisms of mutations and chromosomal effects; health consequences of genetic damage, including cancer and inheritable mutations; properties of physical, chemical, and biological mutagens; risk assessment of human exposure to genotoxicants; and the current position of some government regulatory agencies in the United States on the issues of genetic toxicology. The book will be a useful reference for students and researchers in toxicology, genetics, cancer biology, and medicine who are interested in the basic and applied principles of genetic toxicology. It will also benefit industrial toxicologists, products registration specialists, and government regulatory specialists with responsibility for the safety evaluation of industrial and environmental agents.

Book Description
Genetic toxicology is recognized by geneticists and researchers concerned with the genetic impact of man-made chemicals. In Genotoxicity Assessment: Methods and Protocols, expert researchers in the field provide comprehensive genetic toxicology protocols. These include in vitro and in vivo protocols on mutation assays, cytogenetic techniques, and primary DNA damage, assays in alternate to animal models, and updated ICH guidelines. Written in the highly successful Methods in Molecular Biology series format, the chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step and readily reproducible laboratory protocols, as well as key tips on troubleshooting and avoiding known pitfalls. Authoritative and cutting-edge, Genotoxicity Assessment: Methods and Protocols seeks to aid research students and scientists working in regulatory toxicology as well as biomedical, biochemical and pharmaceutical sciences.

Book Description
The field of genetic toxicology is a relatively new one which grew out of the studies of chemical mutagenesis and modern toxicology. Considering that systematic practices to detect chemical mutagenesis are only a little over thirty years old, this field has evolved very rapidly with an abundance of methods for identifying chemical mutagens. To evalulate the usefulness of the methods and to select the assay which will yield the most important information under practical conditions requires the broad experience such as that which Dr. Brusick has acquired over the last decade. Since this field is expanding very rapidly and new test ing methods are being recognized, it should be kept in mind that revisions may have to be made during the next five to ten years. The need for such a book has been obvious to us, particularly since training courses and workshops on genetic toxicology are being organized which find it beneficial to utilize established guidelines and since the reports in the literature do not always describe in detail how the work was carried out during laboratory testing. In addition to his broad background in genetics, Dr. Brusick has had much practical experience, having organized and directed the most extensive laboratory for mutagen testing. I am most pleased to see this volume, for which there is an ever-increasing need. Alexander Hollaender Associated Universities, Inc. 1717 Massachusetts Avenue, N.W.

Book Description
Genetic toxicology is considered to be an important assessment tool as there is genetic impact of artificial chemicals. Insight on Genotoxicity discusses testing, mechanism, prediction, and bioindicator of genotoxicity taking into consideration recent advances in nano-engineered particles. Corollary of DNA dent is also discussed in detail taking into consideration the impact of ICH guidelines on genotoxicity testing, which is important for drug discovery innovation and development. Perspective review of genotoxicity evaluation in phytopharmaceuticals has been mentioned along with the prevention of genotoxicity in brief viewpoint. Salient Features Presents methods, standard protocols, and guidelines for genotoxicity testing Examines the impact of ICH Guidelines on genetic toxicity testing which is a regulatory requirement for drug discovery and development Defines appropriate strategies about advances in in vivo genotoxicity testing which have been listed along with progress and prospects Discusses advancement in the high-throughput approaches for genotoxicity testing Details computational prediction of genotoxicity with consideration of mutagenicity, chromosomal damage caused and strategies for computational prediction in drug development
