Book Description
Investigates the compound formation, bioactivation, and detoxification of the N-nitroso group of compounds, which increasingly appears to be implicated in human carcinogenesis. The topics include exposure, formation, and blocking; nitric oxide; nitrosamine; toxic, mutagenic, and carcinogenic effects; and reactive intermediates. The 45 papers largely report on research rather than review the literature. The symposium that occasioned them was in Washington, DC, in August 1992.

Book Description
This book provides for the first time a single comprehensive source of information on the analytical chemistry of nicotine and related alkaloids. The editors have brought together scientists from academia and the tobacco industry to describe the state-of-the-art of the chemistry and analytical methods for measurement of nicotine. Both the scope and detail of the book are impressive. Chapters describe the history, pharmacology and toxicology of nicotine, the biosynthesis of nicotine and other alkaloids in the tobacco plant, the general chemistry of nicotine and the analytical methodologies that have been used to measure nicotine and related alkaloids in biological specimens, in tobacco and pharmaceutical products and in tobacco smoke. There is also a comprehensive review of the chemistry and toxicology of nicotine-derived nitrosamines, an important class of tobacco carcinogens.

Book Description
This eighty-ninth volume of the IARC Monographs is the third and last of a series on tobacco-related agents. Volume 83 reported on the carcinogenicity of tobacco smoke and involuntary smoking (second-hand smoke or environmental tobacco smoke) (IARC 2004a). Volume 85 summarized the evidence on the carcinogenic risk of chewing betel quid with and without tobacco (IARC 2004b). That volume explored the variety of products chewed in South Asia and other parts of the word that contain areca nut in combination with other ingredients, often including tobacco. In this eighty-ninth volume, the carcinogenic risks associated with the use of smokeless tobacco, including chewing tobacco and snuff, are considered in a first monograph. The second monograph reviews some tobacco-specific nitrosamines. These agents were evaluated earlier in Volume 37 of the Monographs (IARC 1985) and information gathered since that time has been summarized and evaluated.

Book Description
During the early 1930s, when I was a graduate student and later a post-doctoral researcher at the National Research Council for the University of Wisconsin at Madison, we had the opportunity to get acquainted with many graduate students from China who were sent to the University for training in modern basic sciences as well as social sciences. The University of Wisconsin continues to graduate a large number of Chinese students. Economic conditions in the 1930s were very precarious for the United States and other parts of the world. Many of us students grew closer together because we were living on similarly tight budgets. As a matter of fact, we subleased a part of our apartment in Madison to some Chinese graduate students. This was a very nice opportunity for us to learn about the scientific and cultural back ground of our Chinese friends. Many of them came from the interior of China and had had very little opportunity to become acquainted with people from a western culture. Living with these students was a very pleasant and educational experience which gave us a good pic ture of the cultural life and educational system of China at that time--an intimate picture that one normally would not see without travelling in that country.

Book Description
The material presented in this book deals with basic mechanisms of free radical reactions in autoxidation processes and anitoxidant suppression of autoxidation of foods, biochemical models and biologi cal systems. Autoxidation in foods and corresponding biological effects are usually approached separately although recent mechanistic developments in the biochemistry and free radical chemistry of per oxides and their precursors tend to bring these two fields closer. Apparent ability of antioxidants in diets to reduce the inci dence of cancer has resulted in scrutiny of autoxidized products and their precursors as possibly toxic, mutagenic and carcinogenic agents. Mechanisms of any of these effects have been barely ad dressed. Yet we know now that free radicals, as esoteric as they were only a few decades ago, are being discovered in foods, biochem ical and biological systems and do play a role in the above-mentioned causalities. The purpose of the Workshop and the resulting book was to give a unifying approach towards study of beneficial and deleterious effects of autoxidation, based on rigorous scientific considerations. It is our hope that the material presented in this book will not only provide a review of the "state of the art" of autoxidation and anti oxidants, but also reflect the interaction which occurred during the Workshop between workers using model sytems, and food and biological systems.

Book Description
This book is designed to collect and review the research covering main directions in investigations of aromatic nitroso compounds in last decades, and to present both, the academic aspects of this chemistry, as well as the open field of its applicability. The book is divided in five chapters. The basic structural properties of the nitroso aromatic molecules are described in the first chapter. The second chapter is an overview of the methods of preparations of aromatic nitroso and polynitroso compounds, including classical synthetic methods and some new preparative approaches. The third part deals with the physico-chemical properties of nitroso aromates and azodioxides, its structure, crystallography, quantum chemical calculations, spectroscopy, typical reactions, and especially it is focused on the dimerizations in the solid-state. In the fourth chapter is represented organometallic chemistry of nitroso aromatic molecules and its applications in catalysis. The last part of the book deals with the behavior of this class of compounds in the biological systems, reactions with biomolecules and the use in toxicology.

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.

Book Description
Since 1988, there has been much literature published on the chemistry of nitric oxide, particularly in the field of S-nitrosation and the chemistry of S-nitroso compounds. Written by a chemist for the chemistry community, this book provides an update of the chemistry of nitrosation reactions, dealing with both the synthetic and mechanistic aspects of these reactions. It also looks at the chemistry of nitric oxide in relation to the amazing biological properties of this simple diatomic molecule, which were unknown until around 1990.* Provides an update on previously published literature on nitric oxide chemistry* Contains chapters on reagents for nitrosation, nitrosation at nitrogen, aliphatic and aromatic carbon, oxygen, sulfur and metal centres* Looks at hot research topics such as synthesis, properties and reactions of s-nitrosothiols
