Demography in Ecotoxicology focuses on the interface between toxicology, life history and demographic theory. This comprehensive book examines the different ways of adequately assessing the potential impact of toxic stress on populations and discusses how to obtain an insight into the underlying physiological and genetic mechanisms. The theory is illustrated with empiricial observations on a number of species and organisational levels and the book incorporates:

• case studies;
• real data;
• life history models;
• methodologies; and,
• recommendations for risk assessment

The field of nanotechnology has developed very rapidly over the past decade lending great promise to medical applications in drug delivery, therapeutics, and biological imaging. Due to the great promise, rapid development, and broad application of nanomaterials, it is imperative that researchers from development through application seek a thorough understanding of nanotoxicity. Nanotoxicity: Methods and Protocols address the special considerations when applying toxicity studies to nanomaterials and detail newly developed methods for the study of nanotoxicity. These diverse methods span in vitro cell culture, model tissues, in situ exposure, in vivo models, analysis in plants, and mathematical modeling, proving to be relevant to pharmaceutical scientists, material scientists, bioengineers, toxicologists, environmentalists, immunologists, and cellular and molecular biologists, to name a few. As part of the highly successful Methods in Molecular Biology (TM), chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Comprehensive and cutting-edge, Nanotoxicity: Methods and Protocols aims to diversify the capabilities of current researchers involved in nanotoxicology and to enable researchers in related fields to expand their knowledge of how nanomaterials interface with the biological environment.

This is the first book about both normal development of the nervous system and how early exposure to alcohol and nicotine interferes with this development. The developing nervous system is highly dynamic and vulnerable to genetic and epigenetic factors that can be additive or synergistic. Disruption of normal brain development leads to an array of developmental disorders. One of the most common of these is mental retardation, the prime cause of which is prenatal exposure to alcohol. As chapters in this book show, alcohol has direct effects on the developing neural system and it affects genetic regulation. Another common neurotoxin is nicotine, and it is discussed in this book for three reasons: (1) the number of adolescents who smoke cigarettes is rising in some populations; (2) prenatal exposure to nicotine affects neurotransmitter systems that are critical for normal brain development and cognition; and (3) prenatal exposure to nicotine is often accompanied by prenatal exposure to alcohol.LThe mature brain is the culmination of an orderly sequence of the basic ontogenetic processes--cell proliferation, migration, differentiation, and death. Neural stem cells and progenitors proliferate in discrete sites; then, young neurons migrate long distances to their residences where they form neural networks. During this sequence many immature cells die, presumably eliminating unsuitable or non-competitive cells. Each process is regulated by genetic and environmental factors. When this regulation goes awry, a dysmorphic and dysfunctional brain results. Though this can be tragic in clinical settings, in experimental contexts it provides keen insight into normal brain development.LThe book isdivided into three parts. The first describes neural ontogeny in the normal brain. The second and third deal with the consequences of early exposure to alcohol and nicotine. Though there are similarities in the effects of these two toxins, there are also intriguing differences. The commonalities reflect the plasticity and resilience of the developing brain while the differences point to the targeted effects of the two toxins. Exploring these effects brings a richer appreciation of brain development. The book will be of interest to neuroscientists, developmental biologists, teratologists, pharmacologists, toxicologists, neurologists, neuropsychologists, and to their students and trainees.

An enormous amount of research is currently devoted to evaluating the role of nutrition in the aetiology of major human diseases and to clarifying the underlying mechanisms. This resurgent interest reflects the realisation that carcinogens may be generated during the normal cooking of food and that they may play a role in human carcinogenesis. Moreover, during the last decade it has become apparent that naturally occurring chemicals in food, primarily of plant origin, can afford effective protection against human cancer and heart disease. As a result, the need for up-to-date information in this subject area has never been greater. Nutrition and Chemical Toxicity deals in depth with the various toxicants found in food including naturally occurring chemicals, fungal contaminants, products of the cooking process and allergens. Other chapters focus on nutritional modulation of cytochromes P450; interactions between drugs and diet; glutathione, sulphur aminoacids and chemical detoxication; modulation of the carcinogenic response by caloric restriction; and lipotropes and chemical carcinogenesis. Further contributions discuss the expression of chemical toxicity in vitamin deficiency and supplementation; safety evaluation of vitamins and minerals; naturally occurring organosulphur compounds as potential anticarcinogens; cancer chemoprevention by tea polyphenols; and animal diets in safety evaluation studies. This timely book is essential reading for professionals involved in cancer research and the safety evaluation of chemicals, food scientists and toxicologists, nutritionists and those involved with food regulation.

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

In 1966, Vittorio Erspamer, the editor of the first monograph within the Handbook of Experimental Pharmacology series that dealt with 5-hydroxy- tryptamine (Vol. XIX) wrote in the Preface: "In a decade of intense and dedicated work, an immense amount of experimental data has been collected, the significance of which ...has spread into all fields of biology and medi- cine ...". Three decades later, a dramatic further increase in our knowledge of all neuroscientific aspects of the serotoninergic system in the CNS has been achieved, and we are witnessing persisting interest in the biology of serotonin of scientists working in various basic biomedical and clinical disciplines. The scientific advance was made possible by significant improvements in analytical and morphological technologies of high sensitivity and cellular/subcellular resolution (e. g. , patch clamp techniques, in vivo microdialysis, electrophysi- ological recording techniques, quantitative ligand autoradiography, immuno- histochemistry, cytochemistry, catalytic enzyme histochemistry, and PET / SPECT techniques) and in molecular biology (e. g. , in situ hybridization, PCR cloning, DNA transfection studies, and targeted gene disruption). Particular progress has been made in the anatomy, physiology, and pharmacoogy of ' serotoninergic neurons and their modulatory role in brain functions, in s ~roto- nin receptors and their transduction mechanisms, and in the potential role of serotonin in neuropsychiatric diseases, such as eating disorders, antisocial personality disorders, obsessive-compulsive disorder, seasonal affective disor- der, and major depression.

Vitamin C, or ascorbic acid, has a long and multifaceted scientific history. In 1937, the Nobel Prize for Physiology and Medicine was awarded to Albert Szent-Gyorgyi'in recognition of his discoveries concerning the biological oxida tion processes with special reference to vitamin C', and the Nobel Prize for Chemistry was shared by Sir Norman W. Haworth, who was the first to synthesize the vitamin. Vitamin C is a potent antioxidant, and this action represented the theoretical basis for various lines of investigation on this molecule in which the potential role of ascorbic acid in the prevention and treatment of a series of dis eases, whose pathogenesis is linked to an excess of free radicals such as athero sclerosis and cancer, have been examined. These data have been analyzed in detail by experts in biochemistry, epidemi ology, and preventive and clinical medicine in the International Symposium Vitamin C, the state of the art in disease prevention sixty years after the Nobel Prize, held in Monte Carlo from October 31 to November 1, 1997, under the aus pices and the scientific endorsement of the Nutrition Foundation of Italy and with the financial support of Bracco SpA and Merck."

Human monitoring as a supplement to or replacement for environmental monitoring of toxic substances in the workplace has become an increasingly important issue within the last decade, leading to Congressional hearings, governmental studies, and scientific conferences around the world. Just as the purposes for undertaking human monitoring are diverse and sometimes conflicting, so too are the concerns-- medical, legal, and ethical-- such testing has generated.

The authors begin by providing precise characterizations of the types of monitoring now in use and a clear account of the legal basis for OSHA monitoring requirements. They then turn to scientific and technical concerns that have evolved around monitoring, including the frequency and timing of examinations, human variability, and the distinctions that exist between high-risk and sensitive groups. Specific legal and ethical problems of conducting monitoring tests on workers are then covered in full, including the consequences for the worker of medical removal from the workplace, the conflict between human monitoring and personal privacy, access to medical records, and the use and possible misuse of test results.

The volume concludes with policy recommendations for the use of human monitoring, recommendations for the use of human monitoring, recommendations that would achieve the goal of reducing occupational disease and injury while remaining within the bounds of a supportable ethical framework.

Ecotoxicology is a relatively new scientific discipline. Indeed, it might be argued that it is only during the last 5-10 years that it has come to merit being regarded as a true science, rather than a collection of procedures for protecting the environment through management and monitoring of pollutant discharges into the environment. The term 'ecotoxicology' was first coined in the late sixties by Prof. Truhaut, a toxicologist who had the vision to recognize the importance of investigating the fate and effects of chemicals in ecosystems. At that time, ecotoxicology was considered a sub-discipline of medical toxicology. Subsequently, several attempts have been made to portray ecotoxicology in a more realistic light. Notably, both Moriarty (1988) and F. Ramade (1987) emphasized in their books the broad basis of ecotoxicology, encompassing chemical and radiation effects on all components of ecosystems. In doing so, they and others have shifted concern from direct chemical toxicity to humans, to the far more subtle effects that pollutant chemicals exert on natural biota. Such effects potentially threaten the existence of all life on earth. Although I have identified the sixties as the era when ecotoxicology was first conceived as a coherent subject area, it is important to acknowledge that studies that would now be regarded as ecotoxicological are much older.

This introduction to the mechanisms by which the body metabolizes and excretes administered drugs is directed at advanced undergraduate biochemists, pharmacologists, pre-clinical medical strudents and advanced undergraduate/postgraduate toxicologists. The subject is approached from both biochemical and physiological angles. The examples of drug metabolism have been kept clinically relevant, so that the practical importance of the subject can be easily appreciated. The book contains a section of experimental procedures for setting up student practicals in drug metabolism.

Shortlisted for the BMA Book Awards and Macavity Awards 2016 Fourteen novels. Fourteen poisons. Just because it's fiction doesn't mean it's all made-up ... Agatha Christie revelled in the use of poison to kill off unfortunate victims in her books; indeed, she employed it more than any other murder method, with the poison itself often being a central part of the novel. Her choice of deadly substances was far from random - the characteristics of each often provide vital clues to the discovery of the murderer. With gunshots or stabbings the cause of death is obvious, but this is not the case with poisons. How is it that some compounds prove so deadly, and in such tiny amounts? Christie's extensive chemical knowledge provides the backdrop for A is for Arsenic, in which Kathryn Harkup investigates the poisons used by the murderer in fourteen classic Agatha Christie mysteries. It looks at why certain chemicals kill, how they interact with the body, the cases that may have inspired Christie, and the feasibility of obtaining, administering and detecting these poisons, both at the time the novel was written and today. A is for Arsenic is a celebration of the use of science by the undisputed Queen of Crime.

The last few years have brought about many changes in the field of marine and freshwater toxins, with advances in analytical technology and the realization that these toxins are a global issue.

Over 150 figures and tables help to describe the latest advances and give examples of their applications. Current chiral analysis methods as well as discussions on the impact of chirality are described. Practical aspects of bioanalytical work, including many examples of laboratory problems not often reported in the scientific literature, are examined in depth.

The dramatic development of chromatographic techniques, specially high per formance or high pressure liquid chromatography (HPLC) has made possible the easy analysis of organic compounds, including drugs and drug components, for last two decades. This rapid increase and improvement of analytical methodology with HPLC has enabled researchers and scientists to cope with other scientific and instru mental developments in their fields of work. Thousands of impressive and original scientific publications, text books and monographs describe the techniques for drug analysis with high performance liquid chromatography. However, no concise presentation of the general proper ties of the drugs and their HPLC methodology exists together in the market. This work contains the general properties necessary for the analysis of 232 drugs as well as the HPLC methods for many other drugs and drug components. It is hoped that it will fill a gap and provide a precise survey of the HPLC methods for drug analysis. It is intended as an immediate guide in the laboratory and will be of help to the scientists, researchers and technicians in the field of analysis.

This book contains selected papers from a workshop on modern statistical methods in toxicology held during the EUROTOX '90 conference in Leipzig. The papers deal with the biostatistical evaluation of the commonly used toxicological assays, i.e. mutagenicity, long-term carcinogenicity, embryotoxicity and chronic toxicity assays. The biological background is considered in detail, and most of the related statistical approaches described. In five overview papers, the present state of the art of the related topics is given, while in several contributed papers new approaches are discussed. The most important features are: - A new view on the per-litter analysis problem in em- bryotoxicity assays. - A highly sophisticated treatment of the so-called muta-tox problem in mutagenicity assays. - A detailed discussion of the multiplicity problem based on the closed testing procedure. This volume provides readers with an overview of modern biostatistical methods for several toxicological assays and is in part intended for direct, practical use.
