Mutations in the X-chromosome of Drosophila melanogaster are phenotypically expressed in males carrying the mutant gene. When the mutation is lethal in the hemizygous condition, its presence is inferred from the absence of one class of male ...

Toxicity and Toxicodynamics, Volume One in the Essentials of Pharmatoxicology in Drug Research series provides an overview on the essentials of toxicology, risk assessment and the mechanisms. Topics discussed include the types of cellular responses to chemical toxicants, mechanisms of drug toxicity, and their relevance to pharmaceutical product development. The book examines omics and computer-aided technologies for mechanistic and predictive toxicology and covers state-of-art testing in the evaluation of detrimental pathways, dose selection in toxicity studies, as well as the role of regulatory agencies in toxicity studies. In addition, there is also discussion on clinical interventions such as pharmacotherapy and managed care strategies for acute poisoning. This volume is a valuable resource to those learning more about the drug development process related to toxicology and those who want to get an update on newer concepts on the toxicology aspect of drug research. - Examines toxicological risk assessment in drug research - Discusses toxicity mechanisms - Covers risk assessment and the use of omics and computational technologies in mechanistic and predictive toxicology - Offers clinical interventions and managed care as a result of toxic injury and acute poisoning

This text is divided into three parts. The first part describes basic toxicological concepts and methodologies used in aquatic toxicity testing, including the philosophies underlying testing strategies now required to meet and support regulatory standards. The second part of the book discusses various factors that affect transport, transformation, ultimate distribution, and accumulation of chemicals in the aquatic environment, along with the use of modelling to predict fate.; The final section of the book reviews types of effects or endpoints evaluated in field studies and the use of structure-activity relationships in aquatic toxicology to predict biological activity and physio-chemical properties of a chemical. This section also contains an extensive background of environmental legislation in the USA and within the European Community, and an introduction to hazard/risk assessment with case studies.

Providing a concise, yet comprehensive, reference on all aspects of industrial exposures and toxicants; this book aids toxicologists, industrial hygienists, and occupational physicians to investigate workplace health problems. • Updates and expands coverage with new chapters covering regulatory toxicology, toxicity testing, physical hazards, high production volume (HPV) chemicals, and workplace drug use • Includes information on occupational and environmental sources of exposure, mammalian toxicology, industrial hygiene, medical management and ecotoxicology • Retains a succinct chapter format that has become the hallmark for the previous editions • Distils a vast amount of information into one resource for both academics and professionals

Hayes’ Principles and Methods of Toxicology has long been established as a reliable reference to the concepts, methodologies, and assessments integral to toxicology. The new sixth edition has been revised and updated while maintaining the same high standards that have made this volume a benchmark resource in the field. With new authors and new chapters that address the advances and developments since the fifth edition, the book presents everything toxicologists and students need to know to understand hazards and mechanisms of toxicity, enabling them to better assess risk. The book begins with the four basic principles of toxicology—dose matters, people differ, everything transforms, and timing is crucial. The contributors discuss various agents of toxicity, including foodborne, solvents, crop protection chemicals, radiation, and plant and animal toxins. They examine various methods for defining and measuring toxicity in a host of areas, including genetics, carcinogenicity, toxicity in major body systems, and the environment. This new edition contains an expanded glossary reflecting significant changes in the field. New topics in this edition include: The importance of dose–response Systems toxicology Food safety The humane use and care of animals Neurotoxicology The comprehensive coverage and clear writing style make this volume an invaluable text for students and a one-stop reference for professionals.

Research on gene drive systems is rapidly advancing. Many proposed applications of gene drive research aim to solve environmental and public health challenges, including the reduction of poverty and the burden of vector-borne diseases, such as malaria and dengue, which disproportionately impact low and middle income countries. However, due to their intrinsic qualities of rapid spread and irreversibility, gene drive systems raise many questions with respect to their safety relative to public and environmental health. Because gene drive systems are designed to alter the environments we share in ways that will be hard to anticipate and impossible to completely roll back, questions about the ethics surrounding use of this research are complex and will require very careful exploration. Gene Drives on the Horizon outlines the state of knowledge relative to the science, ethics, public engagement, and risk assessment as they pertain to research directions of gene drive systems and governance of the research process. This report offers principles for responsible practices of gene drive research and related applications for use by investigators, their institutions, the research funders, and regulators.
