Epigenetics is the study of both heritable and non-heritable changes in the regulation of gene activity and expression that occur without an alteration in the DNA sequence. This dynamic and rapidly developing discipline is making its impact across the biomedical sciences, in particular in toxicology where epigenetic differences can mean that different individuals respond differently to the same drug or chemical. Toxicology and Epigenetics reflects the multidimensional character of this emerging area of toxicology, describing cutting-edge molecular technologies to unravel epigenetic changes, the use of in vivo and in vitro models, as well as the potential use of toxicological epigenetics in regulatory environments. An international team of experts consider the interplay between epigenetics and toxicology in a number of areas, including environmental, nutritional, pharmacological, and computational toxicology, nanomaterials, proteomics and metabolomics, and cancer research. Topics covered include: environment, epigenetics and diseases DNA methylation and toxicogenomics chromatin at the intersection of disease and therapy epigenomic actions of environmental arsenicals environment, epigenetics and cardiovascular health toxicology, epigenetics and autoimmunity ocular epigenomics: potential sites of environmental impact in development and disease nuclear RNA silencing and related phenomena in animals epigenomics – impact for drug safety sciences methods of global epigenomic profiling transcriptomics: applications in epigenetic toxicology Toxicology and Epigenetics is an essential insight into the current trends and future directions of research in this rapidly expanding field for investigators, toxicologists, risk assessors and regulators in academia, industry and government.

Environmental stress is one of the most significant factors affecting livestock performance and health, and it is only expected to increase with effects of global warming. Environmental Physiology of Livestock brings together the latest research on environmental physiology, summarizing progress in the field and providing directions for future research. Recent developments in estimating heat stress loads are discussed, as well as key studies in metabolism, reproduction, and genetic expressions. Environmental Physiology of Livestock begins with a survey of current heat indexing tools, highlighting recent discoveries in animal physiology, changes in productivity levels, and new technologies available to better estimate stress response. Using this synopsis as a point of orientation, later chapters hone in on major effects of heat stress, including changing metabolic pathways and nutrient requirements, endocrine regulation of acclimation to environmental stress, and reduced reproductive performance. The text concludes with a thorough discussion of environmental effects on gene expressions, providing important insight for future breeding practices. Environmental Physiology of Livestock is a globally contributed volume and a key resource for animal science researchers, geneticists, and breeders.

The first of its kind, this reference gives a comprehensive but concise introduction to epigenetics before covering the many interactions between hormone regulation and epigenetics at all levels. The contents are very well structured with no overlaps between chapters, and each one features supplementary material for use in presentations. Throughout, major emphasis is placed on pathological conditions, aiming at the many physiologists and developmental biologists who are familiar with the importance and mechanisms of hormone regulation but have a limited background in epigenetics.

The role of epigenetic mechanisms in autoimmune disease is only now starting to become clear. Understanding these mechanisms, their effect on cellular function and the role of environmental factors is vital to determining how to manage these often debilitating and fatal diseases. Drawing on the research of leading experts, this book provides a valuable insight into this important new area of autoimmunity research and a clear, up-to-date view on the major advances in the field. Specific coverage includes: How highly developed epigenetic mechanisms are involved in several aspects of normal immune regulation, in addition to maintaining immune tolerance to self-determinants. Specific epigenetic aspects of human autoimmune diseases, including multiple sclerosis, systemic lupus erythematosus, rheumatoid arthritis, systemic sclerosis, autoimmune diabetes, thyroid autoimmunity, inflammatory bowel disease and autoimmune hepatitis. How understanding epigenetic mechanisms can lead to therapeutic strategies based on manipulation of this previously unexploited facet of immune regulation. Discussion of the novel approaches that are being investigated to prevent or treat autoimmune diseases. This book is an essential resource for those actively involved in the field. It is also of interest to basic researchers interested in understanding the origin of autoimmunity and clinical specialists interested in gaining in-depth understanding of the pathogenesis of autoimmune diseases and their treatment.

The idea that current methods of food production are not sustainable in the long-term is a controversial topic. This book provides information that will advance a form of livestock production that meets the long- and short-term goals of human food production, minimizing degradation of natural resources. Important concerns regarding food safety, particularly antibiotic and chemical residues in meat, milk and other livestock foods, have stimulated renewed interest in alternative methods of promoting livestock health. Alternative Health Practices for Livestock is the first compilation of its kind for veterinarians, agriculture extension educators and livestock producers. It provides a well-referenced overview of some of the alternative livestock practices currently being examined. Key Features: A much needed information source on alternative health for large animals Contributions from veterinarians, farmers, extension educators and university professors Discusses the necessity for more validated scientific assessments of alternative and herbal therapies in livestock production Includes chapters on ways to promote alternative methods of health care for livestock, including steps to obtain research funding.
