This new fifth edition of Information Resources in Toxicology offers a consolidated entry portal for the study, research, and practice of toxicology. Both volumes represents a unique, wide-ranging, curated, international, annotated bibliography, and directory of major resources in toxicology and allied fields such as environmental and occupational health, chemical safety, and risk assessment. The editors and authors are among the leaders of the profession sharing their cumulative wisdom in toxicology's subdisciplines. This edition keeps pace with the digital world in directing and linking readers to relevant websites and other online tools. Due to the increasing size of the hardcopy publication, the current edition has been divided into two volumes to make it easier to handle and consult. Volume 1: Background, Resources, and Tools, arranged in 5 parts, begins with chapters on the science of toxicology, its history, and informatics framework in Part 1. Part 2 continues with chapters organized by more specific subject such as cancer, clinical toxicology, genetic toxicology, etc. The categorization of chapters by resource format, for example, journals and newsletters, technical reports, organizations constitutes Part 3. Part 4 further considers toxicology's presence via the Internet, databases, and software tools. Among the miscellaneous topics in the concluding Part 5 are laws and regulations, professional education, grants and funding, and patents. Volume 2: The Global Arena offers contributed chapters focusing on the toxicology contributions of over 40 countries, followed by a glossary of toxicological terms and an appendix of popular quotations related to the field. The book, offered in both print and electronic formats, is carefully structured, indexed, and cross-referenced to enable users to easily find answers to their questions or serendipitously locate useful knowledge they were not originally aware they needed. Among the many timely topics receiving increased emphasis are disaster preparedness, nanotechnology, -omics, risk assessment, societal implications such as ethics and the precautionary principle, climate change, and children's environmental health.
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 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.
Genetic toxicology is recognized by geneticists and researchers concerned with the genetic impact of man-made chemicals. In Genotoxicity Assessment: Methods and Protocols, expert researchers in the field provide comprehensive genetic toxicology protocols. These include in vitro and in vivo protocols on mutation assays, cytogenetic techniques, and primary DNA damage, assays in alternate to animal models, and updated ICH guidelines. Written in the highly successful Methods in Molecular Biology series format, the chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step and readily reproducible laboratory protocols, as well as key tips on troubleshooting and avoiding known pitfalls. Authoritative and cutting-edge, Genotoxicity Assessment: Methods and Protocols seeks to aid research students and scientists working in regulatory toxicology as well as biomedical, biochemical and pharmaceutical sciences.

This book offers a useful guide for researchers in the field of pharmaceutical sciences and natural medicines as well as students and residents in the fields of pharmacognosy and phytochemistry.
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.
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.
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.
This book provides an overview of Asphyxial Deaths which includes hanging, strangulation, choking, smothering, gagging, drowning, aspiration, mechanical and chemical asphyxiants, etc. Postmortem examination often leads to doubts as a clear distinction between the different type of asphyxia cannot be made easily. 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.
Humans are exposed to foreign compounds such as drugs, household products and environmental chemicals by swallowing or breathing. Also, food is considered a foreign compound. Such foreign compounds can be non-essential and non-functional to life, and commonly are referred to as xenobiotics. Some xenobiotics are not toxic; however, many of them are potentially toxic or become toxic after conversion to metabolic intermediates. A considerable number of foreign compounds belong to non-polar, lipophilic substances. Lipophilic compounds are not soluble in water. Metabolic conversion of lipophilic foreign compounds to facilitate their removal from the body is essentially carried out by biochemical reactions catalyzed by two classes of metabolizing enzymes, namely, activation enzymes and detoxification enzymes. Activation enzyme-catalyzed functionalization reaction introduces a functional group to a lipophilic compound. Functionalization modifies many foreign compounds to form reactive intermediates capable of interacting with cellular components (proteins, DNA and lipids), leading to a variety of conditions for diseases. Functionalized compounds are further metabolized through detoxification enzyme-catalyzed reactions, which result in an increase in the solubility of parent compounds and an inactivation of metabolic intermediates, thus facilitating their excretion from the body. To minimize the exposure of potentially toxic metabolic intermediates, it is essential to keep them at a minimum level. Extensive investigations have revealed that foreign compound-metabolizing enzymes exhibit genetic polymorphisms. Variations in their activities can produce different results as to the susceptibility to potential toxic effects. Moreover, the expressions of activation enzymes and detoxification enzymes are inducible. A number of chemical compounds are capable of acting as modulators for these two classes of enzymes. These findings have lead to the proposal of modulating metabolizing enzymes as a useful approach for human health benefits. Importantly, many of these chemical compounds are present in human daily diets. There are many advances that have been made in the past decades towards the understanding of functions and implications of activation enzymes and detoxification enzymes. An organized, concise overview is needed for the readers who are initially exposed to this important subject, particularly for students and researchers in the areas of biomedical sciences, biochemistry, nutrition, pharmacology and chemistry. This book is intended to serve this purpose as an introduction to the subject. Furthermore, major topics in the book, excluding catalytic reactions and structural properties, may have interest to other readers who have knowledge of basic sciences and understanding enzyme related information. The book discusses subjects associated with foreign compound metabolizing enzymes with emphasis on biochemical aspects, including lipophilic foreign compounds, catalytic properties, reactive intermediates, biomedical and biochemical effects, genetic polymorphisms, enzyme inducibility, enzyme modulation for health benefits, dietary related enzyme modulators, and structural characteristics of enzyme inducers.
Nitrite and Nitrate in Human Health and Disease delivers a comprehensive review of nitrite and nitrate biology, from basic biochemistry to the complex physiology and metabolism of these two naturally occurring molecules in the human body. Well-organized and well referenced chapters cover the rich history of nitrite and nitrate, sources of exposure, and the physiological effects when consumed through foods containing nitrite and nitrate. The chapters are written by leading experts, all of whom share their research and perspectives in order to help define the context for benefits vs. any potential risks associated with nitrite and nitrate use, either through dietary ingestion or therapeutic dosing. This diverse collection of authors includes vascular biologists, physiologists, physicians, epidemiologists, cancer biologists, registered dieticians, chemists, and public health experts from five countries in both academia and government. Nitrite and Nitrate in Human Health and Disease provides a balanced view of nitric oxide biochemistry, and nitrite and nitrate biochemistry in physiology and in the food sciences.
Many unexplored complex cellular and organismal adaptations occur in response to the stress of alcohol exposure, and its contribution to the development of chronic diseases, such as osteoporosis, heart disease and diabetes, is particularly relevant today, given the increased incidence of these diseases in our aging population. In Alcohol: Methods and Protocols, the pleiotropic effects of ethanol in animal and cell culture models are rigorously examined through a collection of detailed procedures written by experts in the field. Sections present clearly defined models of ethanol exposure, recent advances in the development of specific methodologies to mimic the impact of ethanol metabolism in cultured cells, and methodologies to investigate a variety of cells and tissues that are known to be disrupted by ethanol, amongst other topics.
Mercury (Hg) is a global pollutant that knows no environmental boundaries. Even the most stringent control of anthropogenic Hg sources will not eliminate exposure given its ubiquitous presence. Exposure to Hg occurs primarily via the food chain due to MeHg s accumulation in fish. Latest US statistics indicate that 46 States have fish consumption advisories. In addition, Hg is a common pollutant in hazardous waste sites, with an estimated 3-4 million children living within one mile of at least one of the 1,300+ active hazardous waste sites in the US. The effects on intellectual function in children prenatally exposed to MeHg via maternal fish consumption have been the subject of two on-going major, prospective, longitudinal studies in the Seychelles and the Faroe Islands. It is important to recognize that the risk for MeHg exposure is not limited only to islanders with high fish consumption. This bookwill provide state-of-the-art information to the graduate student training in toxicology, risk assessors, researchers and medical providers at large. It is aimed to bring the reader up to date on contemporary issues associated with exposure to methylmercury, from its effects on stem cells and neurons to population studies. "
Scientists and regulators have struggled to define the role of theory, experiments, models and common sense in risk analysis. This situation has been made worse by the isolation of theory from modeling, of experimentation from theory, and of practical action from basic science. This book arises from efforts at regulatory agencies and industries to bring more science into health risk analysis so that society may better use limited resources to improve public health. This book covers: the characterization of exposure to pollutants and other sources of risk; the movement of pollutants into the body via inhalation; ingestion, dermal absorption, and exposures to radiation; the movement of a pollutant as it cascades through the tissues and organs of the body; and the development of principles and models for dose-response modeling. The book shows how an understanding of the biological, chemical, and physical properties of the environment and of the human body can guide the selection of mathematical models, and how these models can aid in estimating risks. Included in the book are models covering the full range of topics in human health risk analysis: exposure assessment, rates of intake, deposition and uptake by organs, absorption across membranes, biokinetics, dosimetry, and dose-response. The reader will gain from the book a better understanding of how environmental health science, as applied in risk analysis, can be used to create a more rational basis for the improvement of public health.
Environmental issues such as ozone layer depletion, overpopulation, biodiversity loss, global warming, natural resource depletion, and so on affect every organism on the planet somehow. Environmental biotechnology applications can help to protect and restore the quality of the environment. The goal is to use biotechnology with other technologies and safety procedures to prevent, arrest, and reverse environmental degradation. Environmental biotechnology is one of the most rapidly expanding and practically useful scientific fields. Biochemistry, physiology and genetic research of microorganisms can be converted into commercially available technologies for reversing and preventing further deterioration of the earth's environment. Solid, liquid, and gaseous wastes can be altered either by recycling new by-products or by purifying to make the end product less harmful to the environment. Biotechnology for Toxic Remediation and Environmental Sustainability discusses the removal of pollutants by absorption techniques and recycling wastewater into valuable by-products and biofuels by microorganisms. Moreover, this book also addresses corrosion prevention by green inhibitors, uses electrochemical systems for renewable energy and waste recycling using microbes, and recent food safety and security trends in the food microbiome. On the other hand, this book also discusses therapy and treatments against antibiotic-resistant bacteria, anti-cancer and pharmacological properties of thymoquinone and preventive properties of zinc nanoparticles against stress-mediated apoptosis in epithelial cells. Features Covers all aspects of Biotechnological application in the environment Discusses sustainable technology for the wastewater treatment and value-added products from wastewater Focuses on research activities Green corrosion inhibitors, bio-electrochemical systems, food safety and security, and antimicrobial resistance The book is a valuable resource for the undergrad and graduate students, doctoral and post-doctoral scholars, industrial personnel, academicians, scientists, researchers, and policymakers involved in understanding and implementing applications of biotechnology for environmental toxic remediation.
Forensic toxicology has progressed rapidly and diversified greatly in recent years. The members of the International Association of Forensic Toxicologists provide a valuable service through the association's bulletin. In its pages members hear of new poisons as they are encountered and the analytical techniques used to deal with them. There is a wealth of information in the form of case reports which is used to assist with the interpretation of the results. Each year the members have the opportunity of meeting in Europe. In 1979 the chosen venue was the University of Glasgow and the meeting was hosted by the Department of Forensic Medicine and Science. The department was established by Royal Charter in 1839 within a few years of the beginning of the modern approach to toxicology. In those early years the function of the department was to teach forensic medicine and toxicology. Today the department has become a recognised centre for the teaching of forensic medicine. The toxicology section has expanded greatly to provide the best forensic and environmental toxicology in Scotland. Inorganic analytical facilities are available for the investigation of metallic poisons by atomic absorption spectrometry, neutron activation analysis, X-ray fluorescence and anodic stripping voltametry. Organic analytical toxicology is pursued using gas chromatography, high performance liquid chromatography, immunoassays, and gas chromatography mass spectrometry. Apart from the normal research and routine investigations of a toxicological laboratory the department specialises in the investigation of fire related deaths, solvent abuse (glue sniffing) and trace element studies in human subjects.
The Permanent Commission and International Association on Occupational Health (PCIAOH) established in 1969 a Subcommittee on the Toxicology of Metals under the chairmanship of Lars Friberg. This committee, which later was named the Scientific Committee on the Toxicology of Metals, has organized a number of previous meetings that have led to publications in three major areas of metal toxicology: a preliminary meeting in Slanchev Bryag, Bulgaria in- 1971, followed by a meeting in 1972 in Buenos Aires, Argentina which produced two reports (Dukes and Friberg, 1971; Task Group on Metal Accumulation, 1973), that discussed the metabolism of metals with special reference to absorption, excretion and biological half-times. The effects and dose-response relationships of toxic metals, including a discussion of general principles, was the second major topic addressed by the Scientific Committee at a meeting in Tokyo in 1974 (Nordberg, 1976). The philosophy of this conference, as well as the previous one in Buenos Aires, was based on the concept of a "threshold dose" for the occurrence of adverse effects. In a conference held in Atlanta, USA in 1980, the scope of discussion on metal effects was broadened to include the role of metals in carcinogenesis. Thus, for the first time, the Scientific Committee took under consideration the possibility of non-threshold relationships (Belman and Nordberg, 1981). In addition, the Scientific Committee on the Toxicology of Metals organized a workshop on metal interactions in Stockholm 1977 (Nordberg et al.
These proceedings focus on the latest research in molecular mechanisms of metal-induced toxicity and carcinogenesis. The conference promoted a multidisciplinary investigative approach and included presentations from international experts on state-of-the-art information in this field.
This book presents a review of the existing literature on natural mycotoxins to create a comprehensive reference for mycotoxin levels. Each entry includes contamination, concentration rate, mostly mean mycotoxin concentration of organs (human and animal) and country of origin of the sample. Due to the serious spoilage and health issues the presence of mycotoxins can cause, it is imperative that corresponding scientists, health institutions and the food and feed industries have a more qualified understanding of mycotoxins in living things. To this end, Natural Mycotoxin Contamination in Humans and Animals provides an excellent resource. The present book complements the series of the author's previous books, Mycotoxins in Feedstuffs and Mycotoxins in Foodstuffs, in that it is a review of the literature to create a comprehensive reference for mycotoxin levels. As with Mycotoxins and their Metabolites in Humans and Animals, the focus remains the same, but the scope now covers natural mycotoxins only. Comprehensive reference of natural mycotoxin levels in humans and animals Easy-to-use database of mycotoxins Each entry is comprehensive
Since the second edition of this text was published, many new environmental incidents have occurred, including another nuclear disaster, a mine disaster in the United States, and the Gulf of Mexico oil spill. Updated throughout the text, Ecosystems and Human Health: Toxicology and Environmental Hazards, Third Edition explores the broad range of environmental and human health aspects of chemical and biological hazards-from natural toxins and disasters to man-made pollutants and environmental crises. The book begins with the basic principles of pharmacology and toxicology, risk analysis, and air, water, and soil pollution. It then examines various toxicants and hazards, such as airborne hazards, halogenated hydrocarbons, metals, and organic solvents. Chapters also discuss food additives and contaminants, pesticides, hormone disrupters, radiation hazards, and natural environmental hazards such as venomous and toxic animals. The text reviews the Chernobyl nuclear crisis and the Walkerton drinking water tragedy, as well as other disasters, assessing some of their long-term effects, now that sufficient time has elapsed since their occurrence. With updates in every chapter, this third edition contains significant expansion of information on the genetics of chemical carcinogenesis, global warming, food additives, invasive species in the Great Lakes, nuclear accidents, and more. The book describes how chemical toxins and biological hazards can impact the environment and the people who live in it. The author presents numerous examples of the relationship between ecosystem health and human health. He emphasizes the need to consider the environmental impact of human activities and includes many real-world examples and new case studies.
The accelerated globalization of the food supply, coupled with
toughening government standards, is putting global food production,
distribution, and retail industries under a high-intensity
spotlight. High-publicity cases about foodborne illnesses over
recent years have heightened public awareness of food safety
issues, and momentum has been building to find new ways to detect
and identify foodborne pathogens and eliminate food-related
infections and intoxications. This extensively revised 4e covers
how the incidence and impact of foodborne diseases is determined,
foodborne intoxications with an introduction noting common features
among these diseases and control measures that are applicable
before and after the basic foodstuff is harvested.
With the rapid growth of the nanotechnology industry, the need to understand the biological effects of aerosol exposure has become increasingly important. Featuring contributions by leading experts in the field, Aerosols Handbook: Measurement, Dosimetry, and Health Effects, Second Edition offers an up-to-date overview of many aspects of aerosols, from properties to health effects and epidemiology. Covering indoor, outdoor, industrial, medical, pharmaceutical, and radioactive aerosols, this book explores aerosol dosimetry by defining terms such as exposure and dose. In addition, it looks at nanometer particles, the mechanism of aerosol deposition in the lungs, and modeling deposition with a corresponding uncertainty in risk assessment. The text also emphasizes the importance of accurate aerosol measurements, particularly breathing zone exposure assessments. Examining radioactive aerosols, the book discusses lessons learned from nuclear accidents, radon and thoron, and long-lived radionuclides in the environment. It brings together research on both radioactive and nonradioactive aerosols, supplying readers with a more complete view of how aerosols behave in the lungs. New in This Edition
Updated throughout, this second edition continues to be an essential resource for those who study exposure, dosages, and toxicity to develop treatments for exposure, reduce air pollution, and establish better safety regulations, particularly in industries using nanotechnologies.
Since the dawn of the industrial age, we have unleashed a bewildering number of potentially harmful chemicals. But out of this vast array, how do we identify the actual threats? What does it take to prove that a certain chemical causes cancer? How do we translate academic knowledge of the toxic effects of particular substances into understanding real-world health consequences? The science that answers these questions is toxicology. In The Alchemy of Disease, John Whysner offers an accessible and compelling history of toxicology and its key findings. He details the experiments and discoveries that revealed the causal connections between chemical exposures and diseases. Balancing clear accounts of groundbreaking science with human drama and public-policy relevance, Whysner describes key moments in the development of toxicology and their thorny social and political implications. The book features discussions of toxicological problems past and present, including DDT, cigarettes and other carcinogens, lead poisoning, fossil fuels, chemical warfare, pharmaceuticals-including opioids-and the efficacy of animal testing. Offering valuable insight into the science and politics of crucial public-health concerns, The Alchemy of Disease shows that toxicology's task-pinpointing the chemical cause of an illness-is as compelling as any detective story.
This publication represents the result of the fruitful workshop organised with the aim to attract the attention on the possibility of bio terrorism attack, with the s- port of NATO funds. In the last years the attention was strongly concentrated on the terrorism view similar to "military type attacks:" bomb on the trains, kamikazes, airplanes etc. As consequence many devices studied are directed to prevent these attacks such as the control of the passengers before the flight. For the people terrorism is therefore equivalent to bomb or similar and nobody think that there is also other possible and sophisticated means that can be used by the terrorist. In 1995 Sarin gas in the Tokio subway killed 12 people and affected 5,000 persons. In the USA anthrax was sent by mail to many federal offices. These events and other cases attract the attention on these possible terrorist attacks and the first recommendations for preventing theses events were\elaborated in the United State and in Europe. The possible agents and the modality that can be used for the diffusion are analysed and food and water are considered the principal and more favourable way. The story and the principal decision about this were reported in the first article of this collection which introduces the concept of bio-terrorism. |
