Book Description
Beginning in the early 1980s, new technologies, began to permit evaluation of the expression of individual genes. Recent technological advances have expanded those evaluations to permit the simultaneous detection of the expression of tens of thousands of genes and to support holistic evaluations of the entire genome. The application of these technologies has enabled researchers to unravel complexities of cell biology and, in conjunction with toxicologic evaluations, the technologies are used to probe and gain insight into questions of toxicologic relevance. As a result, the use of the technologies has become increasingly important for scientists in academia, as well as for the regulatory and drug development process.

Book Description
The new field of toxicogenomics presents a potentially powerful set of tools to better understand the health effects of exposures to toxicants in the environment. At the request of the National Institute of Environmental Health Sciences, the National Research Council assembled a committee to identify the benefits of toxicogenomics, the challenges to achieving them, and potential approaches to overcoming such challenges. The report concludes that realizing the potential of toxicogenomics to improve public health decisions will require a concerted effort to generate data, make use of existing data, and study data in new waysâ€"an effort requiring funding, interagency coordination, and data management strategies.

Book Description
Advances in molecular biology and toxicology are paving the way for major improvements in the evaluation of the hazards posed by the large number of chemicals found at low levels in the environment. The National Research Council was asked by the U.S. Environmental Protection Agency to review the state of the science and create a far-reaching vision for the future of toxicity testing. The book finds that developing, improving, and validating new laboratory tools based on recent scientific advances could significantly improve our ability to understand the hazards and risks posed by chemicals. This new knowledge would lead to much more informed environmental regulations and dramatically reduce the need for animal testing because the new tests would be based on human cells and cell components. Substantial scientific efforts and resources will be required to leverage these new technologies to realize the vision, but the result will be a more efficient, informative and less costly system for assessing the hazards posed by industrial chemicals and pesticides.

Book Description
Toxicogenomics is the integration of genomics to toxicology. This technology is a powerful tool for collecting information from a large number of biological samples simultaneously and thus it is very useful for large-scale screening of potential toxicants. Toxicogenomics: A Powerful Tool For Toxicity Assessment provides up-to-date state-of-the-art information presented by the recognized experts, and is therefore an authoritative source of current knowledge in this field of research. The potential link between toxicology, genetics and human diseases makes this book very useful to investigators in many and varied disciplines of science and toxicology. Topics covered include: mechanistic toxicogenomics analysis and interpretation of toxicogenomic data principles of data mining in toxicogenomics design issues in toxicogenomics studies sources of variability in toxicogenomic assays Escherichia coli stress response as a tool for detection of toxicity toxicogenomics as a tool to assess immunotoxicity toxicogenomics and ecogenomics for studying endocrine disruption and basic biology use of toxicogenomics as an early predictive tool for hepatotoxicity nutrigenomics: the application of genomic signatures in nutrition-related research application of toxicogenomics in drug discovery potential uses of toxicogenomic biomarkers in occupational health and risk assessment usefulness of toxicogenomics in the regulatory environment perspectives on toxicogenomics at the US Environmental Protection Agency Toxicogenomics: A Powerful Tool For Toxicity Assessment is an essential resource for research scientists currently engaged in toxicogenomics, and will also be of interest to researchers working in toxicology, genetics, medicine, pharmacology, and food sciences, and to regulators and risk assessors of drug, food, environmental and agricultural products.

Book Description
Motivated by the explosion of molecular data on humans-particularly data associated with individual patients-and the sense that there are large, as-yet-untapped opportunities to use this data to improve health outcomes, Toward Precision Medicine explores the feasibility and need for "a new taxonomy of human disease based on molecular biology" and develops a potential framework for creating one. The book says that a new data network that integrates emerging research on the molecular makeup of diseases with clinical data on individual patients could drive the development of a more accurate classification of diseases and ultimately enhance diagnosis and treatment. The "new taxonomy" that emerges would define diseases by their underlying molecular causes and other factors in addition to their traditional physical signs and symptoms. The book adds that the new data network could also improve biomedical research by enabling scientists to access patients' information during treatment while still protecting their rights. This would allow the marriage of molecular research and clinical data at the point of care, as opposed to research information continuing to reside primarily in academia. Toward Precision Medicine notes that moving toward individualized medicine requires that researchers and health care providers have access to very large sets of health- and disease-related data linked to individual patients. These data are also critical for developing the information commons, the knowledge network of disease, and ultimately the new taxonomy.

Book Description
This book will be written by experts for professionals, scientists and all those involved in toxicological data generation and decision-making. It is the updated and expanded version of a monograph published in German in 2004. Chemical safety is regulated on various levels including production, storage, transport, handling, disposal or labelling. This book deals comprehensively with the safety-ensuring methods and concepts employed by regulatory agencies, industry and academics. Toxicologists use experimental and scientific approaches for data collection, e.g. about chemical hazards, physicochemical features or toxicokinetics. The respective experimental methods are described in the book. Toxicologists also deal with much insecurity in the exposure and effect scenarios during risk assessment. To overcome these, they have different extrapolation methods and estimation procedures at their disposal. The book describes these methods in an accessible manner. Differing concepts from one regulation area to another are also covered. Reasons and consequences become evident when reading the book. Altogether, the book Regulatory Toxicology will serve as an excellent reference.

Book Description
The human immune system is constantly exposed to chemical contaminants, whether from food, water or air. Some chemicals directly elicit an immune response, while others indirectly activate or deactivate components within the immune system. Thus when tracking or predicting the effect of a chemical on the immune system, many different pathways and modes of action need to be considered. Following an introduction to the various pathways and toxicity mechanisms from a systemic perspective, the main part of this comprehensive reference surveys individual molecular mechanisms of important immunotoxicants, from PAHs to biopharmaceuticals, and from receptor-mediated toxicity to nanoparticle toxicity, using analyses based on molecular effects rather than on animal models. Taken together, the knowledge presented here provides an up-to-date overview of this hot topic that can be directly applied to the prediction and characterization of immunotoxic effects in drugs, chemicals, and environmental contaminants.

Book Description
Risk assessment has become a dominant public policy tool for making choices, based on limited resources, to protect public health and the environment. It has been instrumental to the mission of the U.S. Environmental Protection Agency (EPA) as well as other federal agencies in evaluating public health concerns, informing regulatory and technological decisions, prioritizing research needs and funding, and in developing approaches for cost-benefit analysis. However, risk assessment is at a crossroads. Despite advances in the field, risk assessment faces a number of significant challenges including lengthy delays in making complex decisions; lack of data leading to significant uncertainty in risk assessments; and many chemicals in the marketplace that have not been evaluated and emerging agents requiring assessment. Science and Decisions makes practical scientific and technical recommendations to address these challenges. This book is a complement to the widely used 1983 National Academies book, Risk Assessment in the Federal Government (also known as the Red Book). The earlier book established a framework for the concepts and conduct of risk assessment that has been adopted by numerous expert committees, regulatory agencies, and public health institutions. The new book embeds these concepts within a broader framework for risk-based decision-making. Together, these are essential references for those working in the regulatory and public health fields.
