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 Dehydrobenzene and Cycloalkynes written by Reinhard W. Hoffmann and published by Elsevier. This book was released on 2012-12-02 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dehydrobenzene and Cycloalkynes deals with the problems associated with the production and reactions of dehydrobenzene and of the related fields of dehydroheterocycles and cycloalkynes. This book also describes the various synthetic applications of dehydrobenzene and provides a list of reactions in which dehydrobenzene occurs as an intermediary. The text explains the generation of dehydrobenzene by cleavage of cyclic systems, by photolytic methods, and by free radical reactions. Nucleophilic and electrophilic monodentate attacks on dehydrobenzene, as well as, bidentate additions to dehydrobenzene yielding cycloadducts. The book also notes that dehydrobenzene is not only a transition state but can be an intermediate of characteristic selectivity and lifetime. The reactions of dehydrobenzene in the gaseous phase affirm that the existence of dehydrobenzene is not restricted to the presence of a solvation shell. The researcher can then study the molecular structure of dehydrobenzene when its existence has been fully established. The text also extends the principle that the dehydroaromatic intermediates can be obtained by abstracting two adjacent hydrogen atoms from an aromatic substrate different from the 1- and 2- positions to arrive at a 1,3- and 1,4-dehydrobenzene. Researchers and scientists whose works are associated with organic chemistry, analytical chemistry, molecular physics or physical chemistry will find this book valuable.

This book was released on 2011-02-17 with total page 543 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bread and flour-based foods are an important part of the diet for millions of people worldwide. Their complex nature provides energy, protein, minerals and many other macro- and micronutrients. However, consideration must be taken of three major aspects related to flour and bread. The first is that not all cultures consume bread made from wheat flour. There are literally dozens of flour types, each with their distinctive heritage, cultural roles and nutritive contents. Second, not all flours are used to make leavened bread in the traditional (i.e., Western) loaf form. There are many different ways that flours are used in the production of staple foods. Third, flour and breads provide a suitable means for fortification: either to add components that are removed in the milling and purification process or to add components that will increase palatability or promote health and reduce disease per se. Flour and Breads and their Fortification in Health and Disease Prevention provides a single-volume reference to the healthful benefits of a variety of flours and flour products, and guides the reader in identifying options and opportunities for improving health through flour and fortified flour products. Examines those flour and bread related agents that affect metabolism and other health-related conditions Explores the impact of compositional differences between flours, including differences based on country of origin and processing technique Includes methods for analysis of flours and bread-related compounds in other foods

Available in PDF, EPUB and Kindle. Book excerpt: Discover new keys to solving analytical problems using the Latest sample preparation methods Commonly viewed of as a routine task rather than as an integral component in the analytical process, sample preparation has long been undervalued as a science and underdeveloped as a technology. In an effort to reverse this trend, Handbook of Sample Preparation shows why sample preparation deserves closer scientific scrutiny, and makes a compelling case for colleges and professional laboratories to devote more resources to promote the benefits of its correct application. Handbook of Sample Preparation includes: A solid overview of standard sampling methodologies and their analytical capabilities An introduction of non-traditional sampling technologies, which address the need for solvent-free alternatives, automation, and miniaturization A discussion of the analytical shift toward performing sampling on-site, rather than in the laboratory An examination of various extraction technologies and their applications for different types of matrices A look at how to take advantage of new sampling strategies to streamline laboratory procedures, reduce research costs, and increase overall productivity An excellent primer on the fundamentals of extraction as well as a sound guide on the latest technological upgrades influencing current sampling techniques, this versatile text serves as an important and accessible tool for both students and seasoned practitioners as they seek new avenues for improving the accuracy of their analyses.
