Xenobiotic Metabolic Enzymes: Bioactivation and Antioxidant Defense


Book Description

This book provides a comprehensive, organized, and concise overview of xenobiotic metabolic enzymes and their health implications. The subjects addressed are broad in scope with an emphasis on recent advances in research on biochemical and biomedical aspects of these enzymes. The xenobiotics discussed include not just drugs, but also food, smoke, and other environmental chemicals. The subjects covered in this work include: metabolic enzymes and their catalyzed reactions, reactive intermediates generated from metabolic activation, oxidative stress mediated by electrophilic reactive intermediates, bioactivation - mediated cellular and functional damages, activation of Nrf2 – ARE pathway, genetic variations affecting metabolic enzyme expression, enzyme polymorphisms affecting xenobiotic - mediated toxicity, induction of metabolic enzymes for health benefits, and a diversity of metabolic enzyme modulators.




Molecular, Clinical and Environmental Toxicology


Book Description

Molecular Toxicology is the first volume of a three-volume set Molecular, Clinical and Environmental Toxicology that offers a comprehensive and in-depth response to the increasing importance and abundance of chemicals in daily life. By providing intriguing insights far down to the molecular level, this work covers the entire range of modern toxicology with special emphasis on recent developments and achievements. It is written for students and professionals in medicine, science, public health and engineering who are demanding reliable information on toxic or potentially harmful agents and their adverse effects on the human body.




Radicals for Life


Book Description

Radicals for Life: the Various Forms of Nitric Oxide provides an up-to-date overview of the role of nitrosocompounds and nitrosyl-iron complexes in physiology. Nitrosocompounds can be considered as stabilised forms of nitric oxide, one of the most important regulatory molecules in physiology today. Many nitrosocompounds share some of the physiological functions of nitric oxide, and may be formed inside living organisms. This is the first book to be published that is dedicated to the role of such nitrosocompounds in physiology, with particular emphasis on the nitrosocompounds that are endogenously formed in higher organisms and humans. Points of discussion include: physical and chemical properties of the compounds, the main chemical pathways in vivo, as well as the physiological effects that have been recognised to date. Each of the nineteen chapters is written by distinguished specialists in the field, well known for their original and important contributions to the subject. Also included are results from a wide range of studies in vitro, in cell cultures, animal models and human volunteers. Examples of alternative forms of nitric oxide, with special emphasis on their protective role against widespread human diseases like atherosclerosis, Alzheimer's disease, diabetes, sexual dysfunction, and renal insufficiency to stroke and ischemia are also included. - First monograph to consider and provide an overview of endogenous nitrosocompounds and nitrosyl-iron complexes - Extensive bibliographic references, written by specialists of human physiology - Providing high scientific quality with a focus on implications for human diseases







How Tobacco Smoke Causes Disease


Book Description

This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.




Reaction Mechanisms in Environmental Engineering


Book Description

Reaction Mechanisms in Environmental Engineering: Analysis and Prediction describes the principles that govern chemical reactivity and demonstrates how these principles are used to yield more accurate predictions. The book will help users increase accuracy in analyzing and predicting the speed of pollutant conversion in engineered systems, such as water and wastewater treatment plants, or in natural systems, such as lakes and aquifers receiving industrial pollution. Using examples from air, water and soil, the book begins with a clear exposition of the properties of environmental and inorganic organic chemicals that is followed by partitioning and sorption processes and sorption and transformation processes. Kinetic principles are used to calculate or estimate the pollutants' half-lives, while physical-chemical properties of organic pollutants are used to estimate transformation mechanisms and rates. The book emphasizes how to develop an understanding of how physico-chemical and structural properties relate to transformations of organic pollutants. - Offers a one-stop source for analyzing and predicting the speed of organic and inorganic reaction mechanisms for air, water and soil - Provides the tools and methods for increased accuracy in analyzing and predicting the speed of pollutant conversion in engineered systems - Uses kinetic principles and the physical-chemical properties of organic pollutants to estimate transformation mechanisms and rates




Concepts in Biochemical Pharmacology


Book Description

This volume of the Handbook of Experimental Pharmacology (Concepts in Biochemical Pharmacology) will show that pharma cology has finally arrived as a true discipline in its own right, and is no longer the handmaiden of organic chemistry and physiology. Instead it is an amalgam of all the biological sciences including biochemistry, biophysical chemistry, physiology, pathology and clinical medicine. In the volumes that make up Concepts in Bio chemical Pharmacology we hope to convince Medical Schools what should now be obvious, that pharmacology is no longer that dull topic bridging the basic sciences with medicine, but is probably the most important subject in the medical curriculum. We are grateful for the advice of Dr. Byron Clark, Director of the Pharmacology-Toxicology Program at the National Institutes of Health whose support made possible much of the work described in this volume.

Comprehensive Toxicology


Book Description

An explosive increase in the knowledge of the effects of chemical and physical agents on biological systems has led to an increased understanding of normal cellular functions and the consequences of their perturbations. The 14-volume Second Edition of Comprehensive Toxicology has been revised and updated to reflect new advances in toxicology research, including content by some of the leading researchers in the field. It remains the premier resource for toxicologists in academia, medicine, and corporations. Comprehensive Toxicology Second Edition provides a unique organ-systems structure that allows the user to explore the toxic effects of various substances on each human system, aiding in providing diagnoses and proving essential in situations where the toxic substance is unknown but its effects on a system are obvious. Comprehensive Toxicology Second Edition is the most complete and valuable toxicology work available to researchers today. Contents updated and revised to reflect developments in toxicology research Organized with a unique organ-system approach Features full color throughout Available electronically on sciencedirect.com, as well as in a limited-edition print version
