This text focuses on research procedures in toxicology, aiming to illustrate toxicological concepts and types of toxicity from a mechanistic point of view. Mechanistic research in toxicology leads not only to a greater understanding of the biology involved, but also the means to design substances with selectivity between species and minimal undesirable side effects. Examples of chemical intoxicants are used to illustrate mechanisms in each stage of developing toxicity.

The 3rd edition of Hormones offers a comprehensive treatment of the hormones of humans all viewed from the context of current theories of their action in the framework of our current understanding their physiological actions as well as their molecular structures, and those of their receptors. This new edition of Hormones is intended to be used by advanced undergraduates and graduate students in the biological sciences. It will also provide useful background information for first year medical students as they engage in studies which are increasingly problem-based rather than discipline-focused. As the field of endocrinology itself has expanded so much in the past two decades, the up-to-date presentation of the basics presented in this book will be a solid foundation on which more specialized considerations can be based. New to this Edition: Coverage, for the first time of the following hormones; ghrelin, oxyntomodulin, kisspeptin, adrenomedullin, FGF23, erythropoietin, VIP and extended coverage of NO. Coverage of the hypothalamus has been integrated with the anterior pituitary because of the intimate functional and relationship between the two. The chapter on the thymus has been eliminated as more properly belonging in a book on immunology. Consideration of the role of hormones in cancer has been integrated into the chapters on the relevant hormones. Each of these areas occupies a unique niche in our understanding of the biological world and is part of the universality of signaling systems and how they govern biological systems.
New full color format includes over 600 full color, completely redrawn imagesCompanion web site will host all images from the book as PPT slides and .jpeg filesAll chapters have been completely updated and revitalized. Coverage of the hypothalamus has been integrated into the anterior pituitary chapter and coverage of the thymus has been eliminated and left to immunology textbooks
