Book Description
This book examines genotoxic impurities and their impact on the pharmaceutical industry. Specific sections examine this from both a toxicological and analytical perspective. Within these sections, the book defines appropriate strategies to both assess and ultimately control genotoxic impurities, thus aiding the reader to develop effective control measures. An opening section covers the development of guidelines and the threshold of toxicological concern (TTC) and is followed by a section on safety aspects, including safety tests in vivo and vitro, and data interpretation. The second section addresses the risk posed by genotoxic impurities from outside sources and from mutagens within DNA. In the final section, the book deals with the quality perspective of genotoxic impurities focused on two critical aspects, the first being the analysis and the second how to practically evaluate the impurities.

Book Description
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.

Book Description
About two centuries after the communication by Sir Percival Pott that the "chimney sweeper disease" was a cancer and its suggestion that active compounds of soot were the causative agents, and about one century after the description of urinary bladder cancer in dye workers, an enormous number of substances have been synthesized and have probably come into contact with man. Research in cancer prevention is of primary importance, and may receive continuous support from new discoveries on cancer etiology and pathogenesis. If one accepts the multistage model of chemical carcinogenesis, one has also to accept that many events occur between the contact of carcino genic compounds and their specific targets and the development of a clinically recognizable neoplasm. Thus, animal studies become essential to elucidate the different steps by which chemical carcinogens induce neoplasia. The analysis of these steps and the comparative evaluation of experimental models is essential to an understanding of pathogenesis.

Book Description
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.

Book Description
A working group of sixteen experts from seven countries re-evaluated the evidence of the carcinogenicity of betel-quid and areca-nut chewing and some areca-nut related nitrosamines. Betel-quid and areca-nut chewing are widely practised in many parts of Asia and in Asian-migrant communities elsewhere in the world. There are hundreds of millions of users worldwide. They evaluated betel quid with tobacco as carcinogenic to humans (Group 1) on the basis of sufficient evidence of an increased risk of cancer of the oral cavity, pharynx and oesophagus. The working group reviewed epidemiological studies of human cancer, mainly studies from India, Pakistan and Taiwan (China). Studies on betel quid with tobacco and areca nut with tobacco in experimental animals now also provide sufficient evidence of carcinogenicity. The working group also evaluated betel quid without tobacco as carcinogenic to humans (Group 1), on the basis of sufficient evidence of an increased risk of oral cancer. Studies on betel quid without tobacco and areca nut without tobacco in experimental animals now also provide sufficient evidence of carcinogenicity. Areca nut, a common ingredient of betel quid and many different chewing preparations, including those available commercially, has been observed to cause oral submucous fibrosis

Book Description
Underwood's Pathology (formerly General and Systematic Pathology) is an internationally popular and highly acclaimed textbook, written and designed principally for students of medicine and the related health sciences. Pathology is presented in the context of modern cellular and molecular biology and contemporary clinical practice. After a clear introduction to basic principles, it provides comprehensive coverage of disease mechanisms and the pathology of specific disorders ordered by body system. An unrivalled collection of clinical photographs, histopathology images and graphics complement the clear, concise text. For this seventh edition, the entire book has been revised and updated. Well liked features to assist problem-based learning – including body diagrams annotated with signs, symptoms and diseases and a separate index of common clinical problems – have been retained and refreshed. The advent of whole genome sequencing and increased knowledge of the genetics of disease has been recognised by updated sections in many chapters. Download the enhanced eBook version (from studentconsult.com) for anytime access to the complete contents plus bonus learning materials, including: - clinical case studies – to help apply essential principles to modern practice - the fully revised, interactive self-assessment section with over 200 questions and answers – to check your understanding and aid exam preparation - especially produced video and podcast tutorials – to further explain and bring to life key topics - bonus pathology crosswords – to recall key words and topics in a fun and interactive way This all combines to make Underwood's an unsurpassed learning package in this fascinating and most central medical specialty. From reviews of previous editions: "...it truly is an outstanding textbook...highly recommended" Histopathology "...no doubt it will remain a bestseller – excellent value for undergraduates" Journal of Clinical Pathology "A book of this kind deserves a wide readership" Modern Pathology ".. the definitive textbook of pathology...expands on previous success and cements its position as the market leader for undergraduate pathology" The Bulletin A prize winner: Previous editions have won First Prize in the Medical Writers Group of the Society of Authors Awards, the British Book Design and Production Awards and the British Medical Association Student Textbook Award.
