Clearly linked to consumption of foods, beverages, and drinking water that contain pathogenic microbes, toxins, or other toxic agents, foodborne diseases have undergone a remarkable change of fortune in recent decades, from once rare and insignificant malaises to headline-grabbing and deadly outbreaks. Unquestionably, several factors have combined to make this happen. These include a prevailing demand for the convenience of ready-to-eat or heat-and-eat manufactured food products that allow ready entry and survival of some robust, temperature-insensitive microorganisms; a drastic reduction in the costs of air, sea, and road transportation that has taken some pathogenic microorganisms to where they were absent previously; an expanding world population that has stretched the boundary of human activity; and an ageing population whose weakened immune functions provide a fertile ground for opportunistic pathogens to invade and thrive. Given the diversity of causative agents (ranging from viruses, bacteria, yeasts, filamentous fungi, protozoa, helminthes, toxins, to toxic agents), and the ingenuity of pathogenic microbes to evolve through genetic reassortment, horizontal gene transfer, and/or random genetic mutation, it has become an enormous challenge to understand how foodborne agents are able to evade host immune defenses and induce diseases, and also to develop and apply innovative approaches for improved diagnosis, treatment, and prevention of foodborne diseases. Handbook of Foodborne Diseases summarizes the latest findings on more than 100 foodborne diseases and their causative agents. With contributions from international experts on foodborne pathogens, toxins, and toxic agents research, this volume provides state-of-the-art overviews on foodborne diseases in relation to their etiology, biology, epidemiology, clinical presentation, pathogenesis, diagnosis, treatment, and prevention. Apart from offering a comprehensive textbook for undergraduate and postgraduate students in food, medical, and veterinary microbiology, this volume constitutes a valuable reference on foodborne diseases for medical professionals and health authorities, and forms an informative educational resource for the general public.

Kingship and Masculinity in Late Medieval England explores the dynamic between kingship and masculinity in fifteenth century England, with a particular focus on Henry V and Henry VI. The role of gender in the rhetoric and practice of medieval kingship is still largely unexplored by medieval historians. Discourses of masculinity informed much of the contemporary comment on fifteenth century kings, for a variety of purposes: to praise and eulogise but also to explain shortcomings and provide justification for deposition. Katherine J. Lewis examines discourses of masculinity in relation to contemporary understandings of the nature and acquisition of manhood in the period and considers the extent to which judgements of a king's performance were informed by his ability to embody the right balance of manly qualities. This book's primary concern is with how these two kings were presented, represented and perceived by those around them, but it also asks how far Henry V and Henry VI can be said to have understood the importance of personifying a particular brand of masculinity in their performance of kingship and of meeting the expectations of their subjects in this respect. It explores the extent to which their established reputations as inherently 'manly' and 'unmanly' kings were the product of their handling of political circumstances, but owed something to factors beyond their immediate control as well. Consideration is also given to Margaret of Anjou's manipulation of ideologies of kingship and manhood in response to her husband's incapacity, and the ramifications of this for perceptions of the relational gender identities which she and Henry VI embodied together. Kingship and Masculinity in Late Medieval England is an essential resource for students of gender and medieval history.

Toxicology is the study of the adverse effects of chemical, physical, or biological agents on people, animals, and the environment. Toxicologists are trained to investigate, interpret, and communicate the nature of those effects. Over the last ten years the subject of toxicology has changed dramatically, moving from a discipline which was once firmly wedded to traditional methods to one which is keen to embrace the innovative techniques emerging from the developing fields of cell culture and molecular biology. There is an acute need for this to be reflected in a paradigm shift which takes advantage of the opportunities offered by modern developments in the life sciences, including new in vitro and in silico approaches, alternative whole organism (non-mammalian) models and the exploitation of omics methods, high throughput screening (HTS) techniques and molecular imaging technologies. This concise, accessible introduction to the field includes the very latest concepts and methodologies. It provides MSc, PhD and final year undergraduate students in pharmacy, biomedical and life sciences, as well as individuals starting out in the cosmetics, consumer products, pharmaceutical and testing industries, with everything they need to know to get to grips with the fast moving field of toxicology and the current approaches used in the risk assessment of drugs and chemicals.

Chemical Exposures: Low Levels and High Stakes explains how day-to-day variations in chemical exposure may cause unusual and seemingly unpredictable symptoms, including many that have been termed psychosomatic in the past. It describes how everyday, low-level chemical exposures may cause fatigue, memory impairment, headaches, mood changes, breathing difficulties, digestive problems, and a host of chronic unexplained illnesses including chronic fatigue syndrome, Gulf War syndrome, and sick building syndrome. The authors are the first writers to clearly describe and document the process of adaptation, a concept that provides a rational and scientific basis for understanding these symptoms. In the Second Edition of this professionally acclaimed work, the authors offer evidence for an emerging new theory of disease—toxicant-induced loss of tolerance—which may have far-reaching implications for medicine, public health, and environmental policy. Based on a report commissioned by the New Jersey Department of Health that won the World Health Organization’s Macedo Award, Chemical Exposures is the most comprehensive book ever written on sensitivity to low level chemical exposure and the many health effects associated with it. This work clarifies the nature of chemical sensitivity, shows how it differs from traditional allergies and toxicity, and suggests how federal and state governments can help those who are affected. The book identifies four major groups of people with hypersensitivity to low levels of chemicals: occupants of tight buildings, industrial workers who handle chemicals, residents of communities exposed to toxic chemicals, and individuals with random and unique exposures to various chemicals. The fact that similar symptoms are being reported by members of these demographically diverse groups not only points to a serious problem, it may also contribute to a better understanding of chemical sensitivity. Included are a number of features that will be invaluable to health professionals:

• Clear, concise explanations of technical material
• The most extensive bibliography to date on the subject
• Tables contrasting different medical approaches
• Descriptions of recent research and proposed mechanisms
• An annotated bibliographical appendix highlighting illnesses that have been linked to environmental exposures
• Policy recommendations for federal and state governments

Molecules of Murder is about infamous murderers and famous victims; about people like Harold Shipman, Alexander Litvinenko, Adelaide Bartlett, and Georgi Markov. Few books on poisons analyse these crimes from the viewpoint of the poison itself, doing so throws a new light on how the murders or attempted murders were carried out and ultimately how the perpetrators were uncovered and brought to justice. Part I includes molecules which occur naturally and were originally used by doctors before becoming notorious as murder weapons. Part II deals with unnatural molecules, mainly man-made, and they too have been dangerously misused in famous crimes. The book ends with the most famous poisoning case in recent years, that of Alexander Litvinenko and his death from polonium chloride. The first half of each chapter starts by looking at the target molecule itself, its discovery, its history, its chemistry, its use in medicine, its toxicology, and its effects on the human body. The second half then investigates a famous murder case and reveals the modus operandi of the poisoner and how some were caught, some are still at large, and some literally got away with murder. Molecules of Murder will explain how forensic chemists have developed cunning ways to detect minute traces of dangerous substances, and explain why some of these poisons, which appear so life-threatening, are now being researched as possible life-savers. Award winning science writer John Emsley has assembled another group of true crime and chemistry stories to rival those of his highly acclaimed Elements of Murder.

Nationally, toxicology programs have evolved from a traditional exploration of the chemistry and applied toxicity of chemicals and drugs to a more comprehensive study of toxicology and toxicology testing as independent entities. Consequently, the second edition of Principles of Toxicology Testing starts with basic toxicological principles, including absorption, distribution, metabolism, and elimination of toxins, including chemicals and drugs. The book then continues with animal (in vivo) and in vitro toxicology testing methods associated with toxicological analysis and preclinical drug development. As in the first edition, the book begins with an introduction into the fundamentals of toxicology (Section I) to prepare readers for the subsequent topics and continues through with a discussion of toxicokinetics and human risk assessment. This introductory material is useful in understanding the applications of toxicology testing. Section II describes the fundamental principles of toxicology testing in animals in greater detail. This section describes acute toxicity studies as well as subchronic and chronic studies performed on animals. Special emphasis is placed on study design and determination of classical indicators for acute and chronic testing, such as the LD50. The book examines other short- and long-term animal toxicity testing methodologies, including dermal, ocular, and reproductive toxicity testing. In addition, mutagenicity and carcinogenicity studies are also discussed in separate chapters. Section III introduces and discusses in vitro alternatives to animal toxicology tests. This section emphasizes cell culture methodology and cellular methods for acute systemic toxicity, target organ toxicity, and local toxicity. The contributors present the advantages and disadvantages of alternative methods. They also describe the use of high-throughput screening and its applications, the concepts of standardization and validation of in vitro techniques (especially large, organized validation efforts currently supported by US and EU regulatory agencies), and the theories supporting the development of in vitro methodologies. This second edition is a must-read for undergraduate and graduate toxicology students. Industrial and academic research centers will also find the text useful for establishing a toxicology testing laboratory.

Management of Emerging Public Health Issues and Risks: Multidisciplinary Approaches to the Changing Environment addresses the threats facing the rapidly changing world and provides guidance on how to manage risks to population health. Unlike conventional and recognized risks (major, industrial, and natural), emerging risks are characterized by low or non-existent scientific knowledge, high levels of uncertainty, and different levels of acceptability by the relevant authorities and exposed populations. Emerging risk must be analyzed through multiple and crossed approaches identifying the phenomenon linked to the emergence of risk but also by combining scientific, policy and social data in order to provide more enlightened decision making. Management of Emerging Public Health Issues and Risks: Multidisciplinary Approaches to the Changing Environment provides examples of transdisciplinary approaches used to characterize, analyze, and manage emerging risks. This book will be useful for public health researchers, policy makers, and students as well as those working in emergency management, risk management, security, environmental health, nanomaterials, and food science.

Nanomaterials - substances smaller than 100 nanometers in size - have been added in recent years to an increasing numbers of consumer products used in day-to-day life; in food packaging, medical devices, pharmaceuticals, cosmetics, odor-resistant textiles and household appliances. The extensive application of nanomaterials in a wide range of products for human use poses a potential for toxicity risk to human health and the environment.
