Molecular Biological Markers for Toxicology and Risk Assessment provides an introduction to the exciting field of biomarkers and their use in toxicology and risk assessment. In recent years, new classes of molecular biomarkers capable of detecting early manifestations of ongoing chemical-induced cell injury and cell death have been developed as a result of advances in analytical chemistry, molecular biology, and computational modeling. The interplay between these emergent tools of science has resulted in new insights into initial mechanisms of chemical-induced toxicity and carcinogenicity. Molecular Biological Markers for Toxicology and Risk Assessment guides the reader through a broad range of molecular biological markers, including the "omic" biomarkers, and provides an examination of the various elements in the evolution of these modern tools. It then explores possible ways in which these markers may be applied to advance the field of chemical risk assessment. Since molecular biomarkers and related technologies are inherently complex, the book concludes with a section on risk communication in order that readers may appreciate both the strengths and limitations of molecular biological marker approaches to risk assessment practice.

Foodborne Diseases: Case Studies of Outbreaks in the Agri-Food Industries defines the context of foodborne disease across a range of food sectors. It provides insight into the causes and management of outbreaks along with practical lessons about foodborne disease prevention strategies relevant to stakeholders throughout the food supply chain. Individual chapters capture the epidemiological and traceback investigations of foodborne disease outbreaks in a wide range of food sectors that include fresh produce, dairy and eggs, and meat products, to complex food ingredients and products within the food manufacturing and food service sectors. Under each food category, case studies of real outbreaks are presented, along with lessons learned in the way they were managed for future control of foodborne disease outbreaks. The authors look at management of outbreaks across borders and consider how both local and international authorities dealt with the issues in each case. They focus on real-life microbiological/chemical-associated outbreaks and provide insights on how the outbreaks occurred and, if possible, how they were traced to the source of contamination. Each outbreak is unique, and readers are given the distinctive circumstances associated with different hazards, challenges faced during epidemiological and environmental investigations, risk communication to the general public, and insights into outbreak management. The authors cover the entire food supply chain, including a chapter on animal feed safety. A chapter on fraud and foodborne outbreaks considers scenarios where food industries, food services, and other stakeholders commit food adulteration, which ultimately leads to foodborne illnesses. Outbreak management and prevention strategies are key parts of each case study.

This title includes a number of Open Access chapters. This collection of timely chapters presents a nuanced study of environmental toxins and the risks they pose to children's development. The book details the impact of a number of commonplace environmental toxins, focusing on everyday exposure to tobacco smoke, lead, pesticides, and flame retardants. There is growing recognition that the impact of the environment on children's health is of critical importance for both current and future generations. In the last half-century, thousands of chemicals have been introduced into the environment with limited-although growing-research on the consequences of exposure. It has been proven that children and adolescents are far more vulnerable than adults to these environmental toxins by virtue of children's behaviors, higher metabolic rate, greater skin area relative to their volume, and still developing organ systems. Increased number of ear infections, poor asthma control, and learning disabilities are just some of the adverse outcomes that have been noted. This well-researched book: * Presents detailed information on why children are more vulnerable to everyday toxins * Discusses why new approaches to medical care are necessary that take into account children's unique physiology and development * Offers well-defined research on tobacco smoking on prenatal development as well as children's exposure to tobacco smoke during their early years, particularly the evidence of asthma and asthma-like symptoms * Examines the possible health effects of children born to mothers living in areas of natural gas development * Looks at the health effects of childhood exposure to environmental lead, using GIS technology to study areas of potentially high lead concentrations * Discusses the possible effects of agricultural pesticides on children's health during gestation * Presents studies on prenatal and adolescent exposure to PBDEs used as flame retardants in many household and commercial products to prevent fire This valuable book, edited by a pediatric clinician at Boston's Children's Hospital, provides a wealth of information on this important issue. The book concludes with an article by the World Health Organization, which offers a practical and comprehensive summary of a series of action steps. The book aims to create greater awareness to spur additional research, provide vital information to clinicians, and send a powerful message to government officials, putting pressure on them to develop policies that improve the quality of the environment and spare children the detrimental effects of such exposures.

The growing interest in health risks associated with toxigenic fungi and related mycotoxins has led to the development of a number of research projects during the past decade in several European countries and a great deal of information has been produced on the natural occurrence of mycotoxins in plants, foods and feeds. The differences in environmental conditions (temperature, light, rainfall etc. ) and in exposed cultivated plants (type of cereals, cultivars etc. ) in the distinct European countries have significantly influenced the distribution of specific toxigenic fungi and related mycotoxicological problems. In addition, biogeographically structured lineages within some important toxigenic fungi have been recently discovered, of reproductive isolation. Transglobal showing a long evolutionary history transposition of plant products seems to have significantly contributed to the spreading of toxigenic species and lineages worldwide. Therefore, the migration of agriculturally important toxigenic fungi generated by trade exchanges may represent a major source of inoculum for new plant diseases in Europe and for a wider genetic diversity of local populations. It was our goal to provide the reader with an update of researches and surveys on the natural occurrence of toxigenic fungi and mycotoxins performed at a European level during the last 5-10 years. The editors are extremely grateful to the EU-COST-835 "Agriculturally important toxigenic fungi" for the financial support that allowed a number of European scientists to meet several times over the past five years to collaborate and exchange information about research advances on toxigenic fungi and mycotoxins.

Forensic and physiological aspects are discussed with the help of illustrative cases. The author discusses the different aspects of asphyxia deaths and substantiates multiple case studies to establish a scientific approach that can act as a guideline to the autopsy surgeon in providing a precise opinion and clarify doubts for the judiciary involved in such criminal justice cases. Key Features * Presents individual case studies of Asphyxial deaths. * Covers the guidelines to be followed by the autopsy surgeons in different cases. * Discusses the physiological aspects of Asphyxial deaths in detail. * Illustrates the cases in a stepwise manner with more than 350 colored photographs of postmortem examination.

This book re-evaluates epidemiological and occupational health studies, experimental studies in animals and in vitro experiments relating to the toxicity of 27 metal and metalloid elements for which evidence of carcinogenicity has been presented. Human carcinogenic risk is substantiated in relation to arsenic, beryllium, thorium, chromium, radioactive elements, probably lead, and some nickel and cobalt compounds, and respirable silica particles, but the carcinogenicity of iron, aluminium, titanium, tungsten, antimony, bismuth, mercury, precious metals, and certain related compounds in humans is unresolved. The toxicity and carcinogenicity of each element is specific but correlates poorly with its position in the Periodic Table. Carcinogenicity differs according to the valency of the ion and its ability to interact with and penetrate membranes in target cells and to bind, denature or induce mutations by genotoxic or epigenetic mechanisms. This important text comprehensively examines each of the elements providing detailed information on the carcinogenicity and toxicity and detailing the most up-to-date research in this area. The book will be an essential tool for toxicologists, medicinal and biochemists, and environmental scientists working in both industry and academia.

What do the following have in common: the promise of Botox as the key to everlasting youthful looks; E. coli O157 hamburger disease; a mysterious illness which killed 35 heroin users in 2000; and the assassination by poisoned umbrella-tip of a Bulgarian dissident in the 1970s? The answer is that all of these are caused by toxins, the powerful biological poisons released by bacteria and some plants.
In Toxin, Alistair Lax reveals the panoply of ways in which bacterial toxins overcome the defenses of our cells. He explains how they work, how they are so successful in causing major diseases, the terrible human impact they have had, and how apparently "new" diseases arise from them. He also discusses how we can combat toxins, and how we can harness their actions for beneficial purposes. Enlivened by the very human story of the persistence, rivalries, and insights from which modern microbiology grew, Toxin is the first widely accessible account of this exciting and important topic.
