Book Description
Toxicology – the study of the adverse effects of chemicals on living organisms is the cornerstone to all aspects of chemical safety and knowledge of the subject is needed in a wide spectrum of fields from the chemical industry to medicine, emergency services, forensics, and regulatory science. Toxicology involves the study of symptoms, mechanisms, treatments and detection of poisoning ... especially the poisoning of people. The many problems arising from a poor understanding of toxicology and its applications in hazard communication and chemical safety motivated the author's training courses and webinars, leading to this valuable book. Providing a practical and accessible guide, A Practical Guide to Toxicology and Human Health Risk Assessment enables readers to quickly build up knowledge and understanding of toxicology and its use in hazard identification, which is a fundamental part of chemical risk assessment. The book also covers current toxicological testing strategies and the use of physicochemical test data in hazard identification and exposure assessment. Examples are provided throughout the book to highlight important issues along with a summary of the key points that have been covered in each of the respective chapters. The book concludes with a listing of online resources on toxicology and risk assessment.

Book Description
Drug Safety Evluation Comprehensive and practical guide presenting a roadmap for safety assessment as an integral part of the development of drugs and therapeutics This fourth edition of Drug Safety Evaluation maintains the central objective of presenting an all-inclusive practical guide for those who are responsible for ensuring the safety of drugs and biologics to patients, healthcare providers, those involved in the manufacture of medicinal products, and all those who need to understand how the safety of these products is evaluated and shepherding valuable candidates to market. Individual chapters address specific approaches to evaluation hazards, including problems that are encountered and their solutions. Also covered are the scientific and philosophical bases for evaluation of specific concerns (e.g., carcinogenicity, development toxicity, etc.) to provide both understanding and guidance for approaching the new problems that have come to face both our society and the new challenges they brought. The many changes in regulatory requirements, pharmaceutical development, technology, and the effects of Covid on our society and science have required both extensive revision to every chapter and the addition of four new chapters. Specific sample topics covered in Drug Safety Evaluation include: The drug development process and the global pharmaceutical marketplace and regulation of human pharmaceutical safety Sources of information for consideration in study and program design and in safety evaluation Electronic records, reporting and submission, screens in safety and hazard assessment, and formulations, routes, and dosage regimens Mechanisms and endpoints of drug toxicity, pilot toxicity testing in drug safety evaluation, and repeat dose toxicity Genotoxicity, QSAR tools for drug safety, toxicogenomics, nonrodent animal studies, and developmental and reproductive toxicity testing An appendix which provides an up to date guide to CROs for conducting studies Drug Safety Evaluation was written specifically for the pharmaceutical and biotechnology industries, including scientists, consultants, and academics, to show a utilitarian yet scientifically valid path to the everyday challenges of safety evaluation and the problem solving that is required in drug discovery and development.

Book Description
Principles of Tumors: A Translational Approach to Foundations, Second Edition, provides a concise summary of translational/interdisciplinary topics on the various aspects of tumors, especially abnormalities in their cells, their causes and effects on patients. Topics discussed include how genomic abnormalities in tumors may result from the actions of carcinogens and how genomic changes determine the cell biological/morphological abnormalities in tumor cell populations. In addition, the relationships between tumor cell genomics and therapeutic outcomes are described. There are also supporting appendices on general bioscience, including the principles of histology (the cells and tissues of the body), genetics, pathology, radiology and pharmacology. This book gives a thorough, detailed, yet concise account of the main bioscience, clinical and therapeutic aspects of tumors. It emphasizes the translational aspects of research into tumors with extensive discussions of interdisciplinary issues. The content in this book will be invaluable for researchers and clinicians involved in collaborative projects where it is necessary to understand fundamental issues in other branches of biomedicine. - Presents content that has been totally updated with the most recent developments of the field, including new chapters on tumor imaging exams, new surgical techniques, immunotherapy, gene therapy, and several novel therapies using natural and synthetic compounds - Presents translational approaches for every topic to improve conceptual insights for new research projects - Covers a broad range of subjects, making it easier for the reader to understand related fields - Includes diagrams for complex topics to aid in understanding for non-specialists

Book Description
By means of this ‘Frontiers in Genetics’ research topic, we are celebrating 30 years of the Comet Assay. The first paper on this single-cell gel electrophoresis assay was published in 1984 by O. Ostling and K.J. Johanson (Biochem. Biophys. Res. Commun. Vol.123: 291-298). The comet assay is a versatile and sensitive method for measuring single - and double-strand breaks in DNA. By including lesion-specific enzymes in the assay, its range and sensitivity are greatly increased, but it is important to bear in mind that their specificity is not absolute. The comet assay (with and without inclusion of lesion-specific enzymes) is widely used as a biomarker assay in human population studies - primarily to measure DNA damage, but increasingly also to assess the capacity of cells for DNA repair. Ostling and Johanson (Biochem. Biophys. Res. Commun., 1984) were also the first to report experiments to measure DNA repair, by simply following the decrease of DNA damage over time after challenging cells with ionising radiation. However, this approach is time-consuming and laborious as it requires an extended period of cell culture and is therefore not ideal for biomonitoring studies, which typically require high-throughput processing of many samples. As an alternative approach, the in vitro comet-based repair assay was developed: a cell extract is incubated with a DNA substrate containing specific lesions, and DNA incisions accumulate. The in vitro comet-based repair assay has been modified and improved over the past decade: it was first devised to measure base excision repair of oxidised purines in lymphocytes (Collins et al., Mutagenesis, 2001), but has since been adapted for other lesions and thus other repair pathways, as well as being applied to tissue samples in addition to cell suspensions. Even after 30 years, the comet assay is still in a growth phase, with many new users each year. Many questions are repeatedly raised, which may seem to have self-evident answers, but clearly, it is necessary to reiterate them for the benefit of the new audience, and sometimes being forced to think again about old topics can shed new light. Different applications of the comet assay are discussed in this special issue, including: genotoxicity testing in different organisms, human biomonitoring, DNA repair studies, environmental biomonitoring and clinical studies. Furthermore, we consider and where possible answer questions, including the ones raised by Raymond Tice at the 8th International Comet Assay Workshop in Perugia (Italy 2009): What is the spectrum of DNA damage detected by the various versions of the comet assay?; What are the limitations associated with each application?; What should be done to standardize the assay for biomonitoring studies?; Can the comet assay be used to monitor changes in global methylation status?; What cell types are suitable for detecting genotoxic substances and their effects in vivo and in vitro?; Can the assay be fully automated?; and more. So this ‘Frontiers in Genetics’ research topic is written for the beginner as well as for the experienced users of the comet assay.
