Download or read book Sulfur Centered Reactive Intermediates in Chemistry and Biology written by C. Chatgilialoglu and published by Springer Science & Business Media. This book was released on 2013-03-08 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: A wonderfully successful NATO Advanced Study Institute on "Sulfur-Centered Reactive Intermediates in Chemistry and Biology" was held 18-30 June, 1989, at the Hotel Villa del Mare in Maratea, Italy. Despite the beautiful setting with mountains behind us and over looking the clear blue Mediterranean Sea under a cloudless sky (and with a private beach available), the lectures were extremely well attended. While some credit can go to the seriousness of the students, more must go to the calibre of speakers and the high quality of C. Chatgilialoglu, and Co-Director, Professor K. -D. their presentations. The Director, Dr. Asmus, are to be congratulated for putting together such an outstanding scientific program. Dr. Chatgilialoglu is also to be commended for arranging an equally stimulating social pro gram which included bus, train and boat trips to many local sites of interest. It was particularly fitting that a meeting on the chemistry and biochemistry of sulfur should be held in Italy since Italian chemists have made major contributions to our under standing of the organic chemistry of sulfur, including the chemistry of its reactive inter mediates. The early Italian interest in sulfur chemistry arose from the fact that Italy, or more specifically, Sicily, was a major world producer of sulfur prior to the development and exploitation of the Frasch process in Texas and Louisiana.

Download or read book Radiation Chemistry written by C.D. Jonah and published by Elsevier. This book was released on 2001-08-23 with total page 776 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the twentieth century, radiation chemistry emerged as a multi-faceted field encompassing all areas of science. Radiation chemical techniques are becoming increasingly popular and are being routinely used not only by chemists but also by biologists, polymer scientists, etc. "Radiation Chemistry: Present Status and Future Trends" presents an overall view of the different aspects of the subject. The chapters review the current status of the field and present the future opportunities in utilizing radiation chemical techniques. This will be of interest to chemists in general and in particular to radiation chemists, chemical kineticists, photochemists, physical-organic chemists and spectroscopists. In view of the diverse nature of the field, the book is a multi-authored effort by several experts in their particular areas of research. Six main areas, both basic and applied, were identified and the book is organized around them. The topics were selected in terms of their relative importance and the contribution of radiation chemistry to the general areas of chemistry, biology and physics. The topics covered are as diverse as gas phase radiation chemistry, the use of radiation chemical techniques, the treatment of water pollutants, the chemical basis of radiation biology, and muonium chemistry. The book also contains an update of the next generation electron accelerators.
Download or read book Elemental Sulfur and Sulfur Rich Compounds II written by Ralf Steudel and published by Springer. This book was released on 2004-01-26 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite more than 200 years of sulfur research the chemistry of elemental sulfur and sulfur-rich compounds is still full of “white spots” which have to be filled in with solid knowledge and reliable data. This situation is parti- larly regrettable since elemental sulfur is one of the most important raw - terials of the chemical industry produced in record-breaking quantities of ca. 35 million tons annually worldwide and mainly used for the production of sulfuric acid. Fortunately, enormous progress has been made during the last 30 years in the understanding of the “yellow element”. As the result of extensive inter- tional research activities sulfur has now become the element with the largest number of allotropes, the element with the largest number of binary oxides, and also the element with the largest number of binary nitrides. Sulfur, a typical non-metal, has been found to become a metal at high pressure and is even superconducting at 10 K under a pressure of 93 GPa and at 17 K at 260 GPa, respectively. This is the highest critical temperature of all chemical elements. Actually, the pressure-temperature phase diagram of sulfur is one of the most complicated of all elements and still needs further investigation.
Download or read book Free Radical Induced DNA Damage and Its Repair written by Clemens Sonntag and published by Springer Science & Business Media. This book was released on 2006-03-20 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: The free-radical chemistry of DNA had been discussed in some detail in 1987 in my book The Chemical Basis of Radiation Biology. Obviously, the more recent developments and the concomitant higher level of understanding of mechanistic details are missing. Moreover, in the living cell, free-radical DNA damage is not only induced by ionizing radiation, but free-radical-induced DNA damage is a much more general phenomenon. It was, therefore, felt that it is now timely to review our present knowledge of free-radical-induced DNA damage induced by all conceivable free-radical-generating sources. Originally, it had been thought to include also a very important aspect, the repair of DNA damage by the cell’s various repair enzymes. Kevin Prise (Cancer Campaign, Gray Laboratory, L- don) was so kind to agree to write this part. However, an adequate description of this strongly expanding area would have exceeded the allocated space by much, and this section had to be omitted. The directors of the Max-Planck-Institut für Strahlenchemie (now MPI für Bioanorganische Chemie), Karl Wieghardt and Wolfgang Lubitz, kindly allowed me to continue to use its facilities after my retirement in 2001. Notably, our - brarian, Mrs. Jutta Theurich, and her right-hand help, Mrs. Rosemarie Schr- er, were most helpful in getting hold of the literature. I thank them very much. Without their constant help, this would have been very difficult indeed.

Download or read book Handbook of Oxidants and Antioxidants in Exercise written by C. Sen and published by Elsevier. This book was released on 2000-02-16 with total page 1219 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interest in the science of exercise dates back to the time of ancient Greece. Today exercise is viewed not only as a leisurely activity but also as an effective preventive and therapeutic tool in medicine. Further biomedical studies in exercise physiology and biochemistry reports that strenuous physical exercise might cause oxidative lipid damage in various tissues. The generation of reactive oxygen species is elevated to a level that overwhelms the tissue antioxidant defense systems resulting in oxidative stress. The Handbook of Oxidants and Antioxidants in Exercise examines the different aspects of exercise-induced oxidative stress, its management, and how reactive oxygen may affect the functional capacity of various vital organs and tissues. It includes key related issues such as analytical methods, environmental factors, nutrition, aging, organ function and several pathophysiological processes. This timely publication will be of relevance to those in biomedical science and was designed to be readily understood by the general scientific audience.

Download or read book Physical and Chemical Mechanisms in Molecular Radiation Biology written by William A. Glass and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fundamental understanding of the production of biological effects by ionizing radiation may well be one of the most important scientific objectives of mankind; such understanding could lead to the effective and safe utilization of the nuclear energy option. In addition, this knowledge will be of immense value in such diverse fields as radiation therapy and diagnosis and in the space program. To achieve the above stated objective, the U. S. Department of Energy (DOE) and its predecessors embarked upon a fundamental interdisciplinary research program some 35 years ago. A critical component of this program is the Radiological and Chemical Physics Program (RCPP). When the RCPP was established, there was very little basic knowledge in the fields of physics, chemistry, and biology that could be directly applied to understanding the effects of radiation on biological systems. Progress of the RCPP program in its first 15 years was documented in the proceedings of a conference held at Airlie, Virginia, in 1972. At this conference, it was clear that considerable progr:ess had been made in research on the physical and chemical processes in well-characterized systems that could be used to understand biological effects. During this period of time, most physical knowledge was obtained for the gas phase because the technology and instru mentation had not progressed to the point that measurements could be made in liquids more characteristic of biological materials.
