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.

Providing detailed examples and valuable discussions of the development of specific methods, approaches, and legislation, this reference presents the latest information on the impact of toxicology on the regulatory process and illustrates the interrelationship between toxicology and the regulation of chemicals, pharmaceutical compounds, and food substances.

This book provides an overview of historical and contemporary cases of homicidal poisoning. While homicidal poisoning is sometimes thought of as a thing of the past, it continues to be a contemporary problem, and in fact the unknown offender rate for poisoning cases is 20-30 times that of other homicide types in contemporary research, and many poisoners commit serial homicides while going undetected.The author of this important and timely work explores the theoretical bases for understanding homicidal poisoning, the nature of poisons used in homicidal cases, the characteristics of poisoners and their victims, and techniques for detection and prevention. This unique book will be of particular interest to: students of criminology (classes dealing with criminal psychology, and murder investigation); students of the history of crime; criminal justice professionals: attorneys, homicide detectives, forensic pathologists, forensic and clinical toxicologists, and other forensic investigators; and all interested in poisons, poisoners and the detection of poisoning. It has relevance to criminology, law and policing, toxicology and forensic science, the history of crime and detection, and criminal psychology. Endorsements: "A most welcomed addition to the important subject of the criminal poisoner. The author has done a fantastic job of researching the world literature, and distilling it down for the reader. The work is very well referenced, and provides critical information for law enforcement, forensic pathologists, and others, that could be dealing with the criminal poisoner." John H. Trestrail IIIToxicologistLos Lunas, New Mexico USA "Dr Michael Farrell has produced a comprehensive and authoritative work on a most serious but often overlooked aspect of criminal assault - the act of poisoning. In the Criminology of Homicidal Poisoning, Farrell seamlessly weaves together the facts about poisons and their use as an instrument of homicide with the context of the larger issue of murder. By examining the poisoner and the victim, the reader is provided a depth of understanding about how a deadly outcome arose and why the choice was made to employ poison to get the grisly job done. With criminal homicide by poisoning making up a small percentage of known crimes, the danger of insufficient scholarly attention is present. Dr Michael Farrell makes a significant contribution to ensure against this potential. As a homicide researcher, I know Criminology of Homicidal Poisoning will join the works I turn to in understanding the nuances of the how and why of homicide." Dr Richard M. Hough, Sr., Criminology and Criminal Justice and Public Administration Program Coordinator, University of West Florida, US "This comprehensive text links forensic toxicology with criminology, making a solid contribution to both fields. Farrell not only describes how homicidal poisoning fits the most popular criminological theories for why people kill but also examines the nature and lethality of various poisons, identifies trends in poisoning, provides a history, and shows offender traits and victim characteristics. In addition, he discusses issues for investigators and prosecutors who will be taking a poisoning case to trial." Katherine Ramsland Professor of forensic psychology at DeSales University, PennsylvaniaPsychology Today

This volume contains Raymond J. Carroll's research and commentary on its impact by leading statisticians. Each of the seven main parts focuses on a key research area: Measurement Error, Transformation and Weighting, Epidemiology, Nonparametric and Semiparametric Regression for Independent Data, Nonparametric and Semiparametric Regression for Dependent Data, Robustness, and other work. The seven subject areas reviewed in this book were chosen by Ray himself, as were the articles representing each area. The commentaries not only review Ray's work, but are also filled with history and anecdotes. Raymond J. Carroll's impact on statistics and numerous other fields of science is far-reaching. His vast catalog of work spans from fundamental contributions to statistical theory to innovative methodological development and new insights in disciplinary science. From the outset of his career, rather than taking the "safe" route of pursuing incremental advances, Ray has focused on tackling the most important challenges. In doing so, it is fair to say that he has defined a host of statistics areas, including weighting and transformation in regression, measurement error modeling, quantitative methods for nutritional epidemiology and non- and semiparametric regression.

While many books are available on disaster medicine, none is specifically devoted to the role of physicians in the management of patients exposed to radiation leakage from a damaged nuclear power plant. Radiation Disaster Medicine aims to fill this void based on the response to the Fukushima nuclear accident. Each chapter addresses principles and practices of radiation medicine within the specific context of that accident. Topics covered include the role of physicians in radiation disasters, the concepts of external and internal exposure, prehospital and hospital response, disaster behavioral health, and radiation emergency response from the perspective of national and international institutions. Most of the contributors are active educators and researchers in radiation medicine with first-hand experience in dealing with prehospital triage and management of patients within secondary and tertiary care hospitals in Japan.

Among the vast array of methods available for biochemical analysis, chromatography occupies a venerable station. Few analytical methods have had such vital impact on the development of clinical chemistry and toxicology. In this book, the editors have assembled a cross-section of contemporary applications of chromatographic methods used in clinical chemistry and toxicology. The opening chapter focuses on QA and QC, emphasizing the importance of validating analytical methods that are used for clinical and forensic purposes Chapters 2 to 6 discuss applications of chromatographic methods in the detection of anabolic steroids in urine; the detection and measurement of popular nutritional supplements; measurement of L-dopa and L-tyrosine as markers of malignant melanoma; capillary zone electrophoresis combined with LC and MS to measure proteins in plasma; use of HPLC to detect abnormally glycosolated transferrin; and the measurement of catecholamines, which are specific markers of neuroendocrine tumors. Chapters 7 to 11 focus on toxicology applications, including a description of the analysis of alcohols and inhalants; LC methods for measuring organophosphate pesticides, and the detection and identification of neurotoxins used as biochemical weapons; and a GC/MS method for measuring g-hydroxybutyrate and analogues. The final two chapters present chromatographic methods adapted to the analysis of heavy metals in biological specimens: LC and ICP to measure arsenic, mercury, selenium, and platinum in a variety of biological matrices; and measurement of heavy metals by generating volatile chelates that are separated by GC and detected by MS.

The twelve applications described in this bookillustrate the versatility of chromatographic methods, and the range of applications to clinical chemistry and toxicology available with this powerful analytical technique. The book provides an overview of useful methods, while emphasizing the contributions that chromatography continues to make in clinical laboratory medicine.

Silver in healthcare has many different facets and since the early concepts of microbiology of the 1880's, has been developed from usage in surgical clips, staples, foil wound dressings and surgical implants, to the widespread and clinically effective antiseptic wound dressings, sutures, catheters, bone and dental implants, and cardiovascular devices of today. From the dawn of human civilisation, silver has had a role of water purification and even now has a role in hospital water systems for control of MRSA and legionnaires disease. Biotechnological advances in recent years have extended the antimicrobial properties of silver into production of hygiene textiles and use in domestic products. Important advances have been made in understanding mechanisms of antimicrobial action of silver, the central importance of ionisation patterns in the presence of body fluids and secretion, and the genetical and molecular profiles of silver resistance. This publication is a comprehensive account of the history of silver in medicine, its clinical benefits and wide advantages as a broad spectrum antimicrobial agent. It is clear from the extensive array of publications in recognised and unofficial press, that many misconceptions and misleading conceptions have been perpetuated, leading to errors in evaluation of the safety of the metal in occupational, domestic and therapeutic situations. The book is unique in that it is the only comprehensive presentation of the toxicology of silver and it identifies the major misconceptions in the safety of silver and interpretation of argyria and argyrosis as central features of silver toxicity. In this book, Dr Lansdown reviews the literature from a clinical and experimental viewpoint, with the benefit of his many years research on silver and experience gained in working with clinicians, healthcare product manufacturers and microbiologists. There is also discussion in the book on the relevance of antimicrobial resistance to silver and deficiencies in present day clinical practice in not evaluating incidences of resistance on a routine basis. The subject matter is presented in a readable fashion and includes reference to use of the metal in such practices as acupuncture and treatment of tropical diseases as practised in some parts of the world, each of which is accompanied by special clinical risk. It is also a collation of current views on the use and efficacy of silver as a broad spectrum antibiotic. The chapters which deal specifically with toxicological aspects of silver in clinical, occupational and environmental issues are central to the book's value. The book is aimed at clinicians, research scientists and product manufacturers and will provide ideas for new research and academic endeavour. It is also essential reading for research students with an interest in metal toxicity and its management in mammalian tissues.

This 1992 volume addresses the problems arising from pollutants that all too commonly contaminate the indoor environment, including biological sources such as bacteria, fungi and moulds, common combustion products, radon and other sources of radiation, solvents used in industry and the home, asbestos and dust pollution. The aim is to provide a balanced account of the health risks associated with these major pollutants and to quantify the scale of the problem on a pollutant-by-pollutant basis. Each chapter covers exposure levels, sources of pollution and routes of uptake, health effects, control measures, and regulatory guidelines.

This Brief provides a comprehensive overview of Trypanosoma cruzi, a parasite that is traditionally considered as exclusively vectorborne, but can be foodborne, and may lead to outbreaks of Chagas disease in consumers. The characteristics of Trypanosoma cruzi and the clinical effects of the disease are covered, including documented outbreaks, regional patterns, and epidemiology. The various transmission routes are outlined, but with specific focus on foodborne transmission. A major emphasis of this text is contamination of fruit juices with Trypanosoma cruzi in, a transmission vehicle with increasing significance in the spread of this parasite. Also outlined is the difficulty of establishing a protocol for detection in food samples. Results on survival of Trypanosoma cruzi in food matrices is considered, as well as current risk assessment procedures and regulations. Different approaches to preventing transmission, including inactivation and decontamination are introduced, but also the importance of targeted educational initiatives, and also with a focus on future detection, prevention, and prevention of contamination of foods with this parasite.

Practical Toxicology: Evaluation, Prediction, and Risk, Third Edition shows how to conduct a program of safety evaluation and testing and then to interpret and apply the resulting data and information in the real world, beginning with the basic concepts in toxicology and progressing to the interpretation of the resulting data. Revised and updated chapters on risk assessment guide the reader to setting the foundations necessary for submission to regulatory authorities. In addition, a new chapter in the book reviews the errors in toxicology, mistakes, misuse, mismanagement, and misunderstanding with a view to avoiding these in the future.

New Chapters in the Third Edition:

Toxicology in silico

Errors in Toxicology

Safety Assessment of Extractables and Leachables.

This new edition follows a practical sequence from introducing the basics of toxicology (including the vital concept of normality in controls) to describing a test program and then interpreting the data and translating that to risk assessment that can be used in a number of real world situations where safety and secure risk assessment are essential. Although written primarily from the perspective of pharmaceutical development, the test designs and toxicological problems encountered in that field are entirely relevant to those with other classes of chemicals, the only difference being the regulatory context. Toxicology is an international discipline and the book has been written to take into account some of the differences in regulatory nuance between the main regions of the world.

Completely revised and written in an easily accessible style, the text address several audiences—from students and post-graduates coming to the subject for the first time to established professionals who find themselves needing to learn about toxicology, toxicity testing, interpretation of the results, and risk assessment. It is intended primarily as a textbook, with case studies and information on where to go to ask questions, but can also be used as a practical reference book. It covers all the basics of toxicology and the main aspects of safety evaluation testing and risk assessment while reviewing critically the current state of the discipline. It also provides a foundation for those seeking registration or certification.

Although it is widely recognized that environmental factors such as smoking, diet, exercise, and socioeconomic status affect the risk of cardiovascular disease, recent work showing the effects of other environmental factors provides a more complete assessment of the situation. This view has emerged from three developments. Firstly, there has been a sudden explosion in the prevalence of diabetes and obesity which indicates a strong environmental component. Secondly, there is an accumulation of evidence suggesting that most cases of these diseases could be prevented by healthy lifestyle choices. Finally, studies have shown that exposure to environmental pollutants has a significant effect on heart disease risk. This book is the first to provide a comprehensive account of the effects of pollutants on heart disease and to integrate this area of research within the overall theme of environmental cardiology. The introductory chapter outlines the effects of different aspects of the environment on heart disease and provides a context for the discussion that follows. Subsequent chapters give an overview of the effects of particulate matter and discuss the epidemiological studies supporting the link. The book then goes on to cover the effects of pollution on different aspects of cardiovascular disease (hypertension, stroke, heart failure, ischemic heart disease and atherogenesis). Because of a close association between diabetes and heart disease, a discussion of the effects of particulate matter on diabetes is also included. Later chapters discuss the effects of individual pollutants such as vehicular emissions, metals and aldehydes. A review on manufactured nanoparticles is incorporated because these particles represent an important new threat to cardiovascular health. The understanding that emerges from this monograph suggests that we must be more alert to the effects of the environment and develop strategies that target, not only the diseased individual, but also the unhealthy, disease-causing environment. It is essential reading for cardiologists, epidemiologists, urban planners and pollution control specialists.

This Brief focuses on Listeria monocytogenes, from isolation methods and characterization (including whole genome sequencing), to manipulation and control. Listeriosis, a foodborne disease caused by Listeria monocytogenes is a major concern for public health authorities. In addition, addressing issues relating to L. monocytogenes is a major economic burden on industry. Awareness of its ubiquitous nature and understanding its physiology and survival are important aspects of its control in the food processing environment and the reduction of the public health concern.

This guide provides an easy-to-use desk reference for diagnostic information on commonly used hematology, clinical chemistry and urinalysis parameters. Additional reference materials are provided as an aid in evaluating clinical pathology data. For many toxicologists, the evaluation of hematology, clinical chemistry and urinalysis data can be the most challenging aspect of animal toxicity studies. In a typical toxicity study, dozens of parameters are measured several times over the course of the study. There may be hundreds of data points, each of which needs to be considered. A Toxicologist's Guide to Clinical Pathology in Animals will serve as an essential primer for toxicologists in training and in industry as well as for researchers and professionals in a veterinary practice or a laboratory.

A mycotoxin is a toxin produced by a fungus under special conditions of moisture and temperature. These fungi are aerobic and microscopic and, moreover, may colonize many kinds of food from the field to the table. Mycotoxins are not only a spoilage issue for food, but in high doses can be a serious health threat for humans. The book will be similar to Weidenborner's previous two books - "Mycotoxins in Feedstuffs" and "Mycotoxins in Foodstuffs" - in that it will be a review of the literature to create a comprehensive reference for mycotoxin levels. It will be his third (and last) book on the topic, this time focusing on the incidence of a mycotoxin in humans and/or animals (natural or artificial incidence). Each entry will include contamination, concentration rate, mean concentration of organs (humans and animals) with a mycotoxin, as well as sample constitution (where possible) and country of origin of the sample.

Information flow as nerve impulses in neuronal circuits is regulated at synapses. The synapse is therefore a key element for information processing in the brain. Much attention has been given to fast synaptic transmission, which predominantly regulates impulse-to-impulse transmission. Slow synaptic transmission and modu lation, however, sometimes have been neglected in considering and attempting to understand brain function. Slow synaptic potentials and modulation occur with a considerable delay in response to the accumulation of synaptic and modulatory inputs. In these contexts, they are plastic in nature and play important roles in information processing in the brain. A symposium titled "Slow Synaptic Responses and Modulation" was held as the satellite symposium to the 75th Annual Meeting of the Physiological Society of Japan on March 30-31, 1998, in Kanazawa. The theme was selected not only for the reason mentioned above, but also because of the considerable involvement of many Japanese scholars in establishing the basic issues. Following the dawn of synaptic physiological research, as Sir John Eccles, Sir Bernard Katz, and Professor Stephen Kuffler carried out pioneer work, Professor Kyozou Koketsu and Professor Benjamin Libet, the students of Sir John Eccles, and their colleagues established the concept of slow synaptic responses and modulation by studying vertebrate sympathetic ganglia. Since then, the concept has been ex panded with detailed investigations of both peripheral and central synapses at the levels of single ion channels, intracellular Ca"+ dynamics, intracellular transduc tion mechanisms, and genes.

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.
