Download or read book Techniques in Free Radical Research written by A.T. Diplock and published by Elsevier. This book was released on 1991-12-11 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: Free radical species are generally short-lived due to their high reactivity and thus direct measurement and identification are often impossible. ESR is the only technique which has the potential for direct detection of radicals but in biological systems even these must be trapped by a spin-trapping agent. Thus most investigations involve recognition of indicators of the presence of radicals in vivo or "FOOTPRINTS" of radical-mediated damage. Techniques in Free Radical Research assembles and critically assesses the most relevant and reliable experimental approaches used towards the measurement of radicals and radical-mediated damage in chemical systems, in cells and in tissues under the following six headings: a) Footprints of DNA damage, b) Footprints of protein damage, c) Footprints of lipid peroxidation, d) Footprints of antioxidant consumption, e) Footprints via indirect radical assays, and f) Footprints via the availability of transition metal complexes.
Download or read book EPR in the 21st Century written by Asako Kawamori and published by Elsevier. This book was released on 2002-07-01 with total page 853 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Proceedings in this volume are a refereed selection of presentations from The Third Asia-Pacific EPR/ESR Symposium (APES'01), held in Kobe, Japan from October 29 to November 1, 2001. Participants from 20 countries from Asia, Australia, Europe, North and South America presented 210 papers, of which 132 are included here. These Proceedings are also a blueprint for development of electron paramagnetic resonance (EPR) / electron spin resonance (ESR) in the Asia-Pacific region in the 21st century. The Symposium reflected a variety of research fields developed over half a century and focuses especially on the most recent developments, such as high-field and high-frequency EPR, which are envisaged to be further developed and applied to various fields in the 21st century. All sessions consisted of Plenary, Invited and Contributed presentations. The Plenary presentations aimed at summarizing the overall developments. Invited presentations, reviewing the most recent developments, and Contributed ones, dealing with original research recently carried out in the EPR/ESR area, were given in one of three parallel sessions. The unique research works presented cover various fields and reflect the existing diversity of applications of the EPR/ESR techniques.

Download or read book Free Radicals written by Neville A. Punchard and published by IRL Press. This book was released on 1996 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the recognition that oxygen and nitrogen radicals are involved in normal cell metabolism, free radical research has begun to feature in most disciplines in the life sciences. Increasingly, their implication in a number of human disease processes is being accepted, altough conclusive evidence is lacking in many instances, partly due to the difficulties in detecting and measuring free radicals that have lifetimes measured in microseconds. This book outlines the latest techniques for quantifying radicals and their effects, and features detailed protocols, hints, and tips for success, troubleshooting comments, sample data, and key literature citations.
Download or read book Research Instrumentation for the 21st Century written by Gary R. Beecher and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Annual Beltsville Symposium serves as a forum for presenting recent developments in basic research that contribute solutions to agricultural problems. The eleventh in this series focuses on instrumentation tech niques which provide powerful new research tools. These tools will provide information that can lead to a better understanding of biological and physical processes critical to the solution of today's agricultural problems. The tools discussed include isotope technology, separation techniques, microscopy, electro-magnetic spectroscopy, resonance and mass spectrometry and microcomputers. This Symposium brought together scientists who are at the forefront of the development of many of these tools and those who are applying them to problems directly related to agricultural research.

Available in PDF, EPUB and Kindle. Book excerpt: Cancer is a great challenge to efficient therapy due to biological diversity. Disturbed oxidative homeostasis in cancer cells certainly contributes to differential therapy response. Further, one of the hallmarks of cancer cells is adaptation which includes fine tuning of the cellular metabolic and signalling pathways as well as transcription profiles. There are several factors which contribute to the tumor diversity and therapy response, and oxidative stress is certainly one of them. Changes in oxygen levels due to hypoxia/reoxygenation during tumor growth modulate antioxidative patterns finally supporting increased cell diversity and adaptation to stressing conditions. Additionally, cancer chemotherapy based on ROS production can also induce also adaptation. To counteract these negative effects natural products are often used for their antioxidant activities as well as photodynamic therapy supported by novel chemosensitizers. Understanding of possible pathways which can trigger antioxidant defence at a certain time during cancer development can also provide possible strategies in fighting cancer.
Download or read book Free Radicals from Basic Science to Medicine written by POLI and published by Birkhäuser. This book was released on 2013-03-11 with total page 540 pages. Available in PDF, EPUB and Kindle. Book excerpt: Free radical-mediated reactions have been well known in chemistry and physical chemistry for many years. Applying this knowledge to living organisms, biochemists have shown that reactive free radicals are formed at many intracellular sites during normal metabolism, and they have started to suggest possible roles in various pathological processes and conditions, for example in radiation damage, in the metabolism of xenobiotics, in carcinogenesis and in metabolic disorders. At present, a large and relevant mass of experimental evidence supports the view that reactive free radicals are involved in the pathogenesis of several diseases and syndromes. This literature has captured the attention and interest of people involved in the biomedical field. Exciting developments in radical research are probable in the near future, establishing a greater interaction between basic science research and medicine. While the task of defining the involvement of free radicals in human pathology is difficult, it is nonetheless extremely important that such interaction be fulfilled as soon as possible. These were the considerations motivating us during the organization of the VI Biennial Meeting of the International Society for Free Radical Research held in Torino, Italy, in June 1992, and also during the preparation of this book. Experts in the various aspects of free radical research were invited to participate in the Torino Meeting and to contribute chapters for this volume.
Download or read book Half a Century of Free Radical Chemistry written by Derek H. R. Barton and published by Cambridge University Press. This book was released on 1993-04-15 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the experience over 25 years of the senior author with the chemistry of organic free radicals. It begins with a mechanistic study of industrial importance on the pyrolysis of chlorinated alkanes. It continues with a theory on the biosynthesis of phenolate derived alkaloids involving phenolate radical coupling. There follows 20 years of practical work to prove the theory correct, especially in the case of morphine alkaloids. The book then describes the work on nitrile photolysis (Barton reaction) which involved the invention of new radical chemistry leading to a simple synthesis of the important hormone, aldosterone. There follows a description of the invention of an important new method for the deoxygenation of biologically important molecules, especially sugars and nucleosides, using radical chemistry applied to thiocarbonyl derivatives. Some years later, in a logical extension to carboxylic acids, another new reaction was invented which provides carbon, nitrogen, oxygen and other radicals under mild conditions. A final chapter summarizes recent applications of thiocarbonyl group derived radical reactions by other authors.
