Anatomy and Histology of the Laboratory Rat in Toxicology and Biomedical Research presents the detailed systematic anatomy of the rat, with a focus on toxicological needs. Most large works dealing with the laboratory rat provide a chapter on anatomy, but fall far short of the detailed account in this book which also focuses on the needs of toxicologists and others who use the rat as a laboratory animal. The book includes detailed guides on dissection methods and the location of specific tissues in specific organ systems. Crucially, the book includes classic illustrations from Miss H. G. Q. Rowett, along with new color photo-micrographs. Written by two of the top authors in their fields, this book can be used as a reference guide and teaching aid for students and researchers in toxicology. In addition, veterinary/medical students, researchers who utilize animals in biomedical research, and researchers in zoology, comparative anatomy, physiology and pharmacology will find this book to be a great resource.

"The Toxicology of Methanol " presents a single source of information and an understanding of the toxicity of methanol from animal data, potential environmental effects as well as human effects. The animal data, which goes to making up the majority of the data on the toxicity of methanol and the mechanism of action, is reviewed as it relates to the potential toxicity in humans.

The first thorough review of cyclooxygenase inhibitors, including their toxicity mechanisms and toxicopathological risks Cyclooxygenases (COXs) are enzymes responsible for the formation of an important class of biological mediators called prostanoids. Prostanoids such as prostaglandins mediate inflammatory and anaphylactic reactions. For those suffering from inflammation and pain, the pharmacological inhibition of COXs, with non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, can provide relief. Yet the use of NSAIDs can trigger toxicological effects as well, leading to potential health risks. Comparative Pathophysiology and Toxicology of Cyclooxygenases provides a comprehensive overview of how COX inhibitors affect various bodily systems, specifically the toxicity mechanisms triggered when the COX enzyme is inhibited. The book provides an introduction to the discovery of cyclooxygenases, their use as therapeutic agents, as well as an historical perspective. Shedding light on the differences in expression, pathophysiology, and toxicology of COX inhibitors across species, the book offers a systematic examination of the effects and pathophysiology of COX inhibitors and their mechanisms of toxicity, beginning with the GI tract. Subsequent chapters cover: * The pathophysiology of COX inhibition on bone, tendon, and ligament healing * COX inhibitors and renal system pathophysiology and mechanisms of toxicity * The pathophysiologic role of COX inhibition in the ocular system * COX inhibition and the respiratory and cardiovascular systems The book also sheds light on the latest research devoted to developing COX inhibitors with no adverse side-effects. The first book to offer a thorough comparative look at the toxicological effects of COX inhibitors throughout the body, this invaluable resource will help advance the research and development of safer and more effective COX drugs.

Our world and bodies are becoming increasingly polluted with chemicals capable of interfering with our hormones and thus, possibly, our present and future neural and mental health. As authors Heather Patisaul and Scott Belcher outline, there is a large lack of data and evidence in this causal relationship, which begs a need for further study to accelerate progress in the endocrinology and neuroendocrinology fields. Endocrine Disruptors, Brain, and Behavior focuses on if and how these chemicals, known as endocrine disrupting compounds (EDCs), affect the development and function of the brain and might be contributing to neural disorders rapidly rising in prevalence. The book provides an overall synthesis of the EDC field, including its historical roots, major hypotheses, key findings, and research gaps. The authors explain why even the concept of endocrine disruption is controversial in some circles, how differing definitions of endocrine disruption and what constitutes an "adverse" outcome on the brain shape public policy, and where the current capacity by different stakeholders (industry, academia, regulatory agencies) to evaluate chemicals for safety in a regulatory context begins and ends. The book concludes with suggestions for future research needs and a summary of emerging technology which might prove capable of more effectively evaluating existing and emerging chemicals for endocrine disrupting properties. As such, it provides the context for interdisciplinary and innovative input from a broad spectrum of fields, including those well-schooled in neuroscience, evolutionary biology, brain, behavior, sex differences, and neuroendocrinology.

The network approaches of systems pharmacology and toxicology serve as early predictors of the most relevant screening approach to pursue both in drug discovery and development and ecotoxicological assessments. Computational approaches have the potential to improve toxicological experimental design, enable more rapid drug efficacy and safety testing and also reduce the number of animals used in experimentation. Rapid advances in availability of computing technology hold tremendous promise for advancing applied and basic science and increasing the efficiency of risk assessment. This book provides an understanding of the basic principles of computational toxicology and the current methods of predictive toxicology using chemical structures, toxicity-related databases, in silico chemical-protein docking, and biological pathway tools. The book begins with an introduction to systems pharmacology and toxicology and computational tools followed by a section exploring modelling adverse outcomes and events. The second part of the book covers the discovery of protein targets and the characterisation of toxicant-protein interactions. Final chapters include case studies and additionally discuss interactions between phytochemicals and Western therapeutics. This book will be useful for scientists involved in environmental research and risk assessment. It will be a valuable resource for postgraduate students and researchers wishing to learn about key methods used in studying biological targets both from a toxicity and pharmacological activity standpoint.

It is London in the 1890s. A young woman has just taken a dose of a tonic she's been given in the belief that it will improve her complexion. About ten minutes pass and she starts to experience breathing difficulties. Another minute and she collapses. Mercifully, death arrives but the poison has not yet finished, for the process of rigor mortis has set in with unusual speed. Her body is frozen into a rigid and contorted mass. This is the horror of strychnine, the nastiest of poisons. Despite knowing all the dreadfulness of this poison, Dr Thomas Neill Cream, the Lambeth Poisoner, used it to kill several prostitutes. And who knows how many other victims experienced the horror of strychnine, for it was by no means an uncommon poison. Today, there may well be more poisons available to the individual than ever before, but there are also advances in medical examination and forensic analysis that increase the likelihood of the poisoner being caught. This book will examine poisons, both natural and man-made menaces, and cases based on a particular poison as well as information about how forensic analysis is conducted. Appealing to scientists and non-scientists alike, this enthralling book will entertain and educate and bring the reader up to date with how important chemical analysis is in crime detection.

This issue of Clinics in Laboratory Medicine, edited by Dr. Martin Bluth, will cover a wide array of topics related to drug testing and toxicology.

Looking at arsenic and its compounds, this book explores the presence of arsenic in food and water, the need to clarify its toxicity, and current scientific and public misconceptions about arsenic. It also looks at the use of arsenic in medicine, from cancer treatments to alternative therapies such as homeopathy. Following on from "Is Arsenic an Aphrodisiac?: The Sociochemistry of an Element", this book continues the authors work in addressing the issues surrounding arsenic. It is a fascinating read for general readers as it unveils the reality of our exposure to arsenic in our daily lives.

New designer drugs, access to databases, and changing availability of samples for analysis have changed the face of modern forensic toxicology in recent years. Forensic Toxicology: Drug Use and Misuse brings together the latest information direct from experts in each sub-field of the discipline providing a broad overview of current thinking and the most innovative approaches to case studies. The text begins with an in-depth discussion of pharmaco epidemiology, including information on the value of nationwide databases in forensic toxicology. The use and abuse of drugs in driving, sport and the workplace are then discussed by industry experts who are conducting case work in their field. Not only are new drug groups discussed (NPS), but also their constantly changing impact on drug legislation. Synthetic cannabinoids, khat and mephodrone are discussed in detail. Following a section devoted to legislation and defence, readers will find comprehensive chapters covering sample choice reflecting the increasing use of hair and oral fluid, and also the less commonly used sweat and nail analysis. New and old case examples are compared and contrasted in the final part of the book, which will enable readers to understand how drugs impact on each other and how the interpretative outcome of a case are dependent on many aspects. From use of pharmaceutical drugs in a clinical setting, through smart drugs to new psychoactive drugs, this book documents the wide range in which drugs today are abused. This book will be an essential resource for postgraduate students in forensic toxicology, and for researchers in forensic toxicology laboratories who need the latest data and knowledge.

This publication offers a comprehensive collection of 70 "building blocks," which are primary prevention strategies that merit consideration by state and local governments and others in position to reduce exposure to hazards in housing and thereby help meet the Healthy People 2010 goal of eliminating childhood lead poisoning. Exemplary strategies span a broad spectrum which includes targeting high-risk properties; widely instituting safe work practices; building community capacity to check for hazards and work safety; delivering hazard assessment, control and prevention services; motivating action; screening high-risk housing; expanding financial resources; strengthening enforcement; raising public awareness and support; and establishing valuable partnerships. A strategy has been considered for inclusion as a building block if it is sensitive to the economics of affordable housing, consistent with the principles of public health, holds the potential for broad-scale impact, stands a reasonable possibility of implementation, and offers promise for reducing lead and other environmental health hazards in high-risk housing. The summary of each building block is coupled with an illustration of how the strategy has been implemented and contact information for at least one individual who is knowledgeable about this activity. The purpose of disseminating Building Blocks for Primary Prevention: Protecting Children from Lead-Based Paint Hazards is to allow programs and policymakers easy access to information about innovative and promising strategies that span the spectrum of primary prevention, from which they may select one or several to pursue based on their jurisdiction's needs and political and economic realities.

Exposure to certain types of mycotoxins, the bioactive secondary metabolites of filamentous fungi, significantly impact the animal industry as well as human health. The contamination of food with mycotoxins is a worldwide problem in animal production and direct consequences are the reducing of food intake and production. In this book, the authors increase the public awareness of the implications of certain types of mycotoxins exposure to promote the health of livestock as well as the general public; an analysis of trichothecens (TCEs), a large group of mycotoxins, and their impact on lifestock health and production are also examined, as well as the occurrence of mycotoxins in animal products such as goat milk. Different strategies implemented for the analysis of a wide spectrum of mycotoxins, as well as their advantages and disadvantages are provided by the authors. In the next few chapters, the occurrence of mycotoxins in cereals and cereal products and in particular, their toxic properties are looked at; a discussion on deoxynivalenol (DON) and related 8-ketotrichothecene mycotoxins, which are extensively distributed in cereal-based foods and feed stuffs worldwide are reviewed; potential toxigenic fungi from diverse habitats are identified with special emphasis on the methods as well as on the genetic markers employed; the importance of performing exposure assessments to Aflatoxin B and some of the most important aspects to consider in the risk assessment process, including the simultaneous presence of other mycotoxins and the challenge of choosing the most suitable method to perform exposure assessment are analyzed; and finally, a review of the occurrence of dietary mycotoxins in Africa as well as the advances in analytical methods of mycotoxin extraction and detection over the last decade is provided.

Botulinism toxins are widely used for the treatment of medical and aesthetic disorders. They are considered the gold standard for the treatment of muscular spasticity and facial dynamics wrinkles. The authors' of this book discuss botulinum toxin resistance in medical and aesthetic arenas; recommendations of dilutions for treatment applications (general recommendations were to inject the toxin diluted, because highly concentrated toxins were believed to be more toxic and dangerous); a novel methodology of transdermal delivery of botulinum toxin with the aid of a dermic pen for hyperhidrosis; emerging treatment options for lower urinary tract symptoms that involve a bladder neck injection of a botulinum toxin; and a discussion on the cases of botulism that arise from consuming certain foods particularly in the Arctic regions.
