Book Description
This volume of the IARC Monographs provides an assessment of the carcinogenicity of fluoro-edenite fibrous amphibole, silicon carbide fibres and whiskers, and carbon nanotubes, including single-walled and multiwalled types. None of these agents had been assessed previously by the IARC Monographs Working Group. The Working Group relied mainly on epidemiological studies to evaluate the carcinogenic hazard to humans exposed to fluoro-edenite fibrous amphibole, an environmental contaminant that was reported to cause mesothelioma in the regional population of Biancavilla, Sicily, Italy. Silicon carbide fibres are by-products of the manufacture of silicon carbide particles by the Acheson process; silicon carbide whiskers are produced by other processes. The evaluations of the fibres and of the occupational exposures associated with the Acheson process were mainly based on epidemiological studies, whereas the assessment of the whiskers--in the absence of epidemiological--was based on carcinogenicity bioassays and consideration of their physical properties. In view of the absence of epidemiological studies on carbon nanotubes and the limited information available from mechanistic data, the evaluations of single-walled and multiwalled carbon nanotubes relied essentially on carcinogenicity bioassays.

Book Description
This book offers an updated review of malignant mesothelioma, including the latest advances in our understanding of its genetic control and molecular biology, as well as pre-clinical and clinical research. It also presents state-of-the-art diagnostic approaches and therapeutic options, and an open discussion on the future prospects for patient management. Malignant mesothelioma is an enormous global health problem related to asbestos exposure. Despite the best efforts of scientists and oncologists, the prognosis for those affected remains poor. Due to anatomical characteristics and non-specific symptoms, the diagnosis of mesothelioma at an early stage is often difficult, while surgery and radiotherapy are only of limited use, even if some multimodality approaches seem promising. In turn, medical treatments are sometimes successful in tumor control, but have little impact on overall survival. However, advances in our understanding of the disease’s biology, together with the availability of new drugs and combinations, make mesothelioma an essential and highly topical field for pre-clinical and clinical studies. This book is subdivided into four parts: epidemiology and preclinical data, diagnosis, therapy, and extrathoracic mesothelioma. It highlights the progress made in a variety of areas – e.g. in vitro and in vivo experimental models, genetics, environment, biomarkers, targeting agents, immunotherapy, metabolic imaging and ongoing clinical trials – and describes the standard clinical management of mesothelioma patients, including those with extra-thoracic localizations. Given its scope, the book offers an invaluable tool for researchers, oncologists and clinicians alike.

All chapters have been updated and over 60 new authors have been added to reflect the dynamic nature of toxicological sciences New topics in this edition include Safety Assessment of Cosmetics and Personal Care Products, The Importance of the Dose/Rate Response, Novel Approaches and Alternative Models, Epigenetic Toxicology, and an Expanded Glossary. The volume is divided into 4 major sections, addressing fundamental principles of toxicology (Section I. "Principles of Toxicology"), major classes of established chemical hazards (Section II. "Agents"), current methods used for the assessment of various endpoints indicative of chemical toxicity (Section III. "Methods"), as well as toxicology of specific target systems and organs (Section IV. "Organ- and System-Specific Toxicology"). This volume will be a valuable tool for the audience that wishes to broaden their understanding of hazards and mechanisms of toxicity and to stay on top of the emerging methods and concepts of the rapidly advancing field of toxicology and risk assessment.

Book Description
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.
