Book Description
The concept that detoxication is the inevitable result of biotransformation of xenobiotic compounds by mammalian systems has undergone modification since it was first described. Indeed, despite the fact that R. T. Williams popularized the notion, he was among the first to caution that it was not possible to predict the biological activities of the resulting metabolites. It has become increasingly apparent in recent years that not only do many metabolites of drugs and other chemicals display biological activity but also in many instances these metabolites play an important role in initiating several forms of cancer and are the cause of a variety of types of toxicity. Thus it seems appropriate to collect in one volume a series of reports outlining advances in the study of the formation of chemically active intermediary metabolic products of chemicals, mechanisms of toxicity or carcinogenesis, and pathways for true detoxication of these chemicals. The work of R. T. Williams, beginning in the late 1920s and early 1930s, marked the first concerted effort to understand the biotransformation of foreign chemicals in animals. He investigated the metabolic pathway of numerous compounds in a wide variety of animal species while training large numbers of our colleagues who have been responsible for further advances in biochemistry, pharmacology, and toxicology. Another pioneer in the study of drug metabo lism, B. B.

Book Description
Much of organic chemistry is based on the ability of suitably structured chemicals to bind together through the formation of covalent bonds. Biochemistry is replete with exam ples of enzymatically catalyzed reactions in which normal body constituents can be linked through covalent bonds during the process of intermediary metabolism. The finding that xenobiotic chemicals that enter the body from the environment, are metabolized to highly reactive species, and then covalently react with cellular macromolecules to induce toxic and carcinogenic effects was an observation that spawned the research featured in the Fifth International Symposium on Biological Reactive Intermediates (BRI V). The group of investigators that became fascinated with this process and its signifi cance in terms of human health began their discussions in Turku, Finland (J 975), and continued them at Guildford, England (1980), College Park, Maryland (1985), Tucson, Arizona (1990), and Munich, Germany (1995). Among the results were a series of reports listed below, as well as the book for which this serves as the Preface. • Jollow, DJ., Kocsis, J.J., Snyder, R. and Vainio, H. (eds), Biological Reactive Intermediates: Formation, Toxicity and Inactivation, Plenum Press, NY, 1975. • Snyder, R., Park, D.V., Kocsis, J.J., Jollow, D.V., Gibson, G.G. and Witmer, C.M.

Book Description
Metalloproteins comprise approximately 30% of all known proteins, and are involved in a variety of biologically important processes, including oxygen transport, biosynthesis, electron transfer, biodegradation, drug metabolism, proteolysis, and hydrolysis of amides and esters, environmental sulfur and nitrogen cycles, and disease mechanisms. EPR spectroscopy has an important role in not only the geometric structural characterization of the redox cofactors in metalloproteins but also their electronic structure, as this is crucial for their reactivity. The advent of x-ray crystallographic snapshots of the active site redox cofactors in metalloenzymes in conjunction with high-resolution EPR spectroscopy has provided detailed structural insights into their catalytic mechanisms. This volume was conceived in 2005 at the Rocky Mountain Conference on Analytical Chemistry (EPR Symposium) to highlight the importance of high-resolution EPR spectroscopy to the structural (geometric and electronic) characterization of redox active cofactors in metalloproteins. We have been fortunate to have enlisted internationally recognized experts in this joint venture to provide the scientific community with an overview of high-resolution EPR and its application to metals in biology. This volume, High-Resolution EPR: Applications to Metalloenzymes and Metals in Medicine, covers high-resolution EPR methods, iron proteins, nickel and copper enzymes, and metals in medicine. An eloquent synopsis of each chapter is provided by John Pilbrow in the Introduction. A second volume, Metals in Biology: Applications of High-Resolution EPR to Metalloenzymes, will appear later this year covering the complement of other metalloproteins. One of the pioneers in the development of pulsed EPR and its application to metalloproteins was Arthur Schweiger, whose contribution we include in this volume. Unfortunately, he passed away suddenly during the preparation of this volume. The editors and coauthors are extremely honored to dedicate this volume to the memory of Arthur Schweiger in recognition of his technical advances and insights into pulsed EPR and its application to metalloproteins. Arthur was extremely humble and treated everyone with equal respect. He was a gifted educator with an ability to explain complex phenomena in terms of simple intuitive pictures, had a delightful personality, and continues to be sadly missed by the community. It is an honor for the editors to facilitate the dissemination of these excellent contributions to the scientific community. Suggestions for future volumes are always appreciated.

Book Description
nd The 22 meeting of the International Society on Oxygen Transport to Tissue (LS. O. T. T. ) of which this volume is the scientific proceedings, was held in Istanbul, Turkey on August 22-26, 1994. It was a historical occasion in that it was almost 200 years to the day that one of the founding fathers of oxygen research, Antoine Lavoisier, on May 8, 1794 found his early demise at the hands of the guillotine. This spirit of history set the tone of the conference and in the opening lecture the contribution that this part of the world has given to the understanding of oxygen transport to tissue was highlighted. In particular, the contribution of Galen of Pergamon (129-200) was discussed who for the first time demon strated that blood flowed through the arteries and whose view on the physiology of the circulation dominated the ancient world for well over a millennium. A forgotten chapter in the history of the circulation of the blood is the contribution made by Ibn al Nafis of Damascus (1210-1280) who for the first time described the importance of the pulmonary circulation by stating that all venous blood entering the right ventricle ofthe heart passes to the left ventricle, not through pores in the septum of the heart as had been postulated by Galen, but through the circulation of the lungs.

Book Description
This conference and monograph were the result of many collective efforts. The whole concept was formulated one early Wednesday morning at our weekly research meeting at Children's Hospital in our division of urology. We have been most fortunate to have a close collaboration with Bob Levin, Ed Macarak, and Pam Howard who have helped steer the course of our division's growing interest in basic science. At our weekly meetings our laboratory fellow will summarize their current work. Other ongoing areas of investigation in our labs and elsewhere are discussed. We have always made an effort to try and understand what other groups are doing who are working in the area of bladder smooth muscle research. It occurred to us that the best way to really know what everyone working in this field was doing would be to sponsor a 2-day meeting where we could all gather to discuss our ongoing work. A major limitation of the annual meeting of the American Urologic Association or the urology section of the American Academy of Pediatrics is that the scientfic sessions are limited as these are meant to be primarily clinical meetings (as they should be). For this reason the idea of a meeting devoted solely to research about the urinary bladder had great appeal. In addition to allowing for longer presentations than the standard 5 to 7 minutes, every effort would be made to encourage a dialogue amongst the presenters and the audience.
