Assembles international authorities to address contemporary research in metal neurotoxicity. Essential and non-essential metals play an important role in neurodevelopmental and neurodegenerative diseases. Recent developments in understanding the role of metals in the etiology of these disorders have led to rapid growth in clarifying the pathology of some of the most devastating diseases we face and in identifying potential new therapies. Few books or periodicals have been wholly dedicated to the topic of metals, and this collection is intended to serve as a resource for all researchers interested in metals and their role in health and disease.

In recent years, the need to develop acceptable alternatives to conventional animal testing for neurotoxicity and developmental neurotoxicity has been increasingly recognized, and much effort is being directed toward the development of alternative models, utilizing mostly mammalian cells in culture but also non-mammalian model systems. In Vitro Neurotoxicology: Methods and Protocols presents a series of cellular, biochemical, and molecular methodological protocols in the area of in vitro neurotoxicology, with an emphasis on mammalian cell culture systems. Opening with a section on methodologies for preparing several cellular systems of variable complexity, amenable for in vitro neurotoxicological studies, the thorough volume continues with coverage of methods to measure cellular death and major mechanisms, methods for assessing mechanisms of nervous system cell toxicity related to impairment of cell signaling, while a final section illustrates additional methods for assessing important nervous system processes such as cell proliferation, neuritogenesis, and synaptogenesis. Written in the highly successful Methods in Molecular Biology (TM) series format, chapters include introductions to their respective subjects, 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, In Vitro Neurotoxicology: Methods and Protocols serves researchers with an interest in assessing or characterizing the potential neurotoxicity of environmental contaminants, drugs, or other chemicals.

This volume presents a collection of selected papers by the prominent Brazilian mathematician Djairo G. de Figueiredo, who has made significant contributions in the area of Differential Equations and Analysis. His work has been highly influential as a challenge and inspiration to young mathematicians as well as in development of the general area of analysis in his home country of Brazil.

In addition to a large body of research covering a variety of areas including geometry of Banach spaces, monotone operators, nonlinear elliptic problems and variational methods applied to differential equations, de Figueiredo is known for his many monographs and books. Among others, this book offers a sample of the work of Djairo, as he is commonly addressed, advancing the study of superlinear elliptic problems (both scalar and system cases), including questions on critical Sobolev exponents and maximum principles for non-cooperative elliptic systems in Hamiltonian form.

This book contains revised and significantly extended versions of selected papers from three workshops on Uncertainty Reasoning for the Semantic Web (URSW), held at the International Semantic Web Conferences (ISWC) in 2008, 2009, and 2010 or presented at the first international Workshop on Uncertainty in Description Logics (UniDL), held at the Federated Logic Conference (FLoC) in 2010. The 17 papers presented were carefully reviewed and selected from numerous submissions. The papers are organized in topical sections on probabilistic and Dempster-Shafer models, fuzzy and possibilistic models, inductive reasoning and machine learning, and hybrid approaches.

The paraoxonase or PON family of genes resides on human chromosome 7q2t-22 in the order PONt, PON3 and PON2. PONt was one of the early genes identified as an environmentally relevant gene, in that it is important in determining an individual's sensitivity or resistance to exposure from specific organophosphorus (OP) insecticides. Paraoxonase (PONt) is an A esterase (i. e., not inhibited by OP compounds) initially identified for its ability to catalytically hydrolyze paraoxon, the toxic metabolite (oxon form) of the insecticide parathion. Evidence accumulated in the past several years has established that this enzyme, which is present at variable levels in liver and serum of different individuals, is an important determinant of sensitivity to toxicity of specific organophosphorus compounds including chlorpyrifos oxon and diazoxon. Recent experiments have pointed out that it is the catalytic efficiency of PONt together with the levels of PONt that are important in determining the degree of resistance. Surprisingly, even though PONt has a higher catalytic efficiency than PONtQ)92 for paraoxon RJ92 hydrolysis, it does not provide significant in vivo protection against an exposure to paraoxon. Interest in this enzyme has also emerged from the finding that it displays genetic polymorphisms in most populations, with a significant number of the individuals in a given population canying a PONt gene that puts them at risk for a specific OP exposure."

The protection of human health and food and fiber resources against the ravages of pests of many sorts is a continuous struggle by all people in the world. The use of chemical pesticides as an aid in this struggle is now also global. These chemicals are deliberately added to the environment for the purpose of killing or injuring some form of life. Because pesticides are generally less selectively toxic than would be desired, non-target species, including humans, must be protected from injury by these chemicals. This can only be achieved by thorough understanding of the comparative toxicology of these compounds, and by minimizing human (and other desirable species) exposure. The latter can only be achieved by sound regulatory policies that utilize scientific principles and data, properly tempered by both gaps in that data and sociologic and economic considerations. This book contains the proceedings of the NATO Advanced Study Institute on "Toxicology of Pesticides: Experimental, Clinical and Regulatory Perspectives" held in Riva del Garda on October 6-15, 1986. This NATO-ASI has been promoted by the School of Public Health and Community Medicine, University of Washington at Seattle, by the Institute of Pharmacological Sciences, University of Milano and by the Giovanni Lorenzini Foundation, and has been sponsored by both the Society of Toxicology (USA) and the Italian Society of Toxicology.

The journey to find genes responsible for determining sensitivity or resistance to specific insecticides led to the paraoxonase (PON1) gene on human chromosome 7. This gene encodes a 355 amino acid protein that is localized on the high density lipoprotein (HDL) particles in plasma. Characterization of this gene revealed that different individuals expressed both different forms of this enzyme with amino acid substitutions at positions 55 and 192 as well as different levels of this protein. Additional studies showed that mutations in the regulatory region of the PON1 gene contributed to the very different levels of plasma PON1 among individuals. It turned out that both the level of the enzyme as well as the amino acid present at position 192 (glutamine or arginine) are important in determining resistance to the active forms of specific organophosphorus insecticides, especially diazinon and chlorpyrifos. The position 192 amino acid also determined whether an individual's plasma hydrolyzed the nerve agents soman and sarin at high or low rates. It is not yet known whether these different rates of hydrolysis observed in biochemical assays reflect differences in sensitivity of individuals to nerve agents. Taken together, all of the experiments carried out to date indicate that engineered recombinant PON1 is an excellent candidate to use for treating cases of poisoning by specific organophosphorus compounds. The available data on the relationship of PON1 levels and position 192 genotype led us to introduce the term PON1 status to describe an individual's PON1 plasma level as well as their position 192 genotype.

The characterization of the genetic variations of the PON1 gene together withexperiments showing that HDL can protect the lipids in low density lipoprotein particles (LDL) from oxidation and that it was PON1 that was responsible for this protection have opened an entirely new area of investigation, the role of PON1 in protecting against vascular disease.

More recent reports have noted that PON1 also metabolizes a number of drugs, activating some and inactivating others.

This book describes the recent advances in understanding the role of PON1 in both cardiovascular disease and toxicology of insecticide exposure as well as some of the recent information indicating an important possible role in the pharmacokinetics of drug metabolism. The final chapter of the book provides an overview of the areas of PON1 research and suggests future directions for research on PON1 as well as the related, linked genes PON2 and PON3.
