Download or read book Free Radicals in Diagnostic Medicine written by Donald Armstrong and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 461 pages. Available in PDF, EPUB and Kindle. Book excerpt: An International Syaposiua on Free Radicals in Diagnostic Medicine was co-sponsored by the state University of New York at Buffalo, Roswell Park Cancer Institute, and the Upstate NY Section of the American Association of Clinical Chemistry. The theme was "A Systems Approach To Laboratory Technology, Clinical Correlations And Antioxidant Therapy." The symposium was held on October 7-8, 1993 at the Hyatt Hotel and on October 9 at Roswell Park Cancer Institute, Buffalo, New York. This proceedings volume contains chapters from platform presentations, poster sessions and from invited special lectures in the areas of basic science, clinical applications and efficacy of treatment. A Special Lecture on the relevance of free radical analysis to clinical medicine was presented by Professor Kunio Yagi of Japan. The Yagi procedure to measure thiobarbituric acid (TBA) reaction reflects the amount of reactive substances, lipid peroxides and aldehydes, in the sample. For example, normal subjects will have less than 4 nmol/ml of serum lipid peroxides, while a person with diabetes generally has equal or greater than 5.0 and a diabetic person with vascular complications often exceeds 7.5 nmol/ml. Serum TBA is a clinically important measure that relates to aging, gender and estrogen as an antioxidant, in the prognosis for vascular disorders, and in pathological conditions relative to the amount of lipid peroxidation. The BASIC SCIENCES portion of the program examined: "Mechanisms of Action, Pathophysiology and Laboratory Tests" in six presentations.

Download or read book Annual Plant Reviews Plant Pigments and their Manipulation written by Kevin Davies and published by John Wiley & Sons. This book was released on 2009-02-12 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Annual Plant Reviews, Volume 14 It is difficult to over-state the importance of plant pigments in biology. Chlorophylls are arguably the most important organic compounds on earth, as they are required for photosynthesis. Carotenoids are also necessary for the survival of both plants and mammals, through their roles in photosynthesis and nutrition, respectively. The other plant pigment groups, such as flavonoids and betalains, have important roles in both the biology of plants and the organisms with which plants interact. This book provides an overview of pigment chemistry and biology, together with an up-to-date account of the biosynthesis of pigments and the modification of their production using biotechnology. The chapters cover a wide scope of pigmentation research - from the importance of structural diversity in generating the range of colours seen in plants, through to improving human health properties of crops by increasing pigment levels in transgenic plants. The volume is directed at researchers and professionals in plant biochemistry, molecular biology and genetics.
Download or read book Structure information from HPLC and on line measured absorption spectra Flavones Flavonols and Phenolic Acids written by Maria da Graça Campos and published by Imprensa da Universidade de Coimbra / Coimbra University Press. This book was released on 2007-01-01 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: The tools used in scientific research are constantly changing and HPLC with photodiode array detection technique has become an important and popular technology used in studies such as plant extract analysis, drug discovery and development, the monitoring of manufacturing processes and quality assurance. The HPLC/photodiode array technique is also an important base tool of pure science. The authors have provided a compilation of valuable and unique reference material, gathered using strictly controlled conditions, and have developed theoretical rules that will aid users of this technique in the identification of the structures of the titled compound types. These compound types are widely encountered in bioactive plant components. The book will have appeal not only to academic chemists but also for example to biologists, food technologists, pharmacologists, pharmacists, the health supplements industry and the colourant industry. To our knowledge this is the first book of its kind to present and interpret a compilation of actual spectra of a series of authentic compounds, measured under identical and defined conditions that practitioners can use for direct comparison with their own data.
