Download or read book Essential Metals in Medicine Therapeutic Use and Toxicity of Metal Ions in the Clinic written by Peggy L. Carver and published by Walter de Gruyter GmbH & Co KG. This book was released on 2019-01-14 with total page 640 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 19, entitled Essential Metals in Medicine: Therapeutic Use and Toxicity of Metal Ions in the Clinic of the series Metal Ions in Life Sciences centers on the role of metal ions in clinical medicine. Metal ions are tightly regulated in human health: while essential to life, they can be toxic as well. Following an introductory chapter briefly discussing several important metal-related drugs and diseases and a chapter about drug development, the focus is fi rst on iron: its essentiality for pathogens and humans as well as its toxicity. Chelation therapy is addressed in the context of thalassemia, its relationship to neurodegenerative diseases and also the risks connected with iron administration are pointed out. A subject of intense debate is the essentiality of chromium and vanadium. For example, chromium(III) compounds are taken as a nutritional supplement by athletes and bodybuilders; in contrast, chromate, Cr(VI), is toxic and a carcinogen for humans. The benefi cial and toxic effects of manganese, cobalt, and copper on humans are discussed. The need for antiparasitic agents is emphasized as well as the clinical aspects of metal-containing antidotes for cyanide poisoning. In addition to the essential and possibly essential ones, also other metal ions play important roles in human health, causing harm (like the metalloid arsenic, lead or cadmium) or being used in diagnosis or treatment of human diseases, like gadolinium, gallium, lithium, gold, silver or platinum. The impact of this vibrant research area on metals in the clinic is provided in 14 stimulating chapters, written by internationally recognized experts from the Americas, Europe and China, and is manifested by approximately 2000 references, and about 90 illustrations and tables. Essential Metals in Medicine: Therapeutic Use and Toxicity of Metal Ions in the Clinic is an essential resource for scientists working in the wide range from pharmacology, enzymology, material sciences, analytical, organic, and inorganic biochemistry all the way through to medicine ... not forgetting that it also provides excellent information for teaching.

Download or read book Dietary Reference Intakes for Vitamin A Vitamin K Arsenic Boron Chromium Copper Iodine Iron Manganese Molybdenum Nickel Silicon Vanadium and Zinc written by Institute of Medicine and published by National Academies Press. This book was released on 2002-07-19 with total page 798 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is the newest release in the authoritative series issued by the National Academy of Sciences on dietary reference intakes (DRIs). This series provides recommended intakes, such as Recommended Dietary Allowances (RDAs), for use in planning nutritionally adequate diets for individuals based on age and gender. In addition, a new reference intake, the Tolerable Upper Intake Level (UL), has also been established to assist an individual in knowing how much is "too much" of a nutrient. Based on the Institute of Medicine's review of the scientific literature regarding dietary micronutrients, recommendations have been formulated regarding vitamins A and K, iron, iodine, chromium, copper, manganese, molybdenum, zinc, and other potentially beneficial trace elements such as boron to determine the roles, if any, they play in health. The book also: Reviews selected components of food that may influence the bioavailability of these compounds. Develops estimates of dietary intake of these compounds that are compatible with good nutrition throughout the life span and that may decrease risk of chronic disease where data indicate they play a role. Determines Tolerable Upper Intake levels for each nutrient reviewed where adequate scientific data are available in specific population subgroups. Identifies research needed to improve knowledge of the role of these micronutrients in human health. This book will be important to professionals in nutrition research and education.
Download or read book Nutritional Bioavailability of Iron written by Constance Kies and published by . This book was released on 1982 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Research results concerning aspects of iron (Fe) bioavailability from various foods and interactions of Fe with other nutrients are reported by experts for nutritionists and food and agricultural chemists. Several areas address the determination of available Fe in foods, changes in Fe availability caused by food processing, physiochemical food properties affecting Fe chemstry, and food additives that either enhance or inhibit Fe intake. Therelationship of ascorbic acid in aiding Fe absorption is discussed, as is the inhibitory action of dietary fiber. Twoimportant human nutrition aspects cover Fe availability in human milk, and the differences in Fe utilization between vegetarians and omnivores. When careful choice is made of food combinations, food additives, and proper processing methods, humans can utilize a greater portion of the Fe in low-energy foods. (wz).
Download or read book Manganese in Soils and Plants written by R.D. Graham and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sixty years ago at the Waite Agricultural Research Institute, G. Samuel, a plant pathologist, and C. S. Piper, a chemist, published their conclusion that the cause of roadside take-all, a disease of oats, was manganese deficiency. This report, together with the concurrent and independent studies of W. M. Carne in Western Australia were the first records of manganese deficiency in Australia and came only six years after McHargue's paper which is generally accepted as the final proof of the essentiality of this element. There must have been a few doubts for some people at the time, however, as the CAB publication, 'The Minor Elements of the Soil' (1940) expressed the view that further evidence to this effect was provided by Samuel and Piper. Their historic contributions are recognised by the International Symposium on Manganese in Soils and Plants as it meets on the site of their early labours to celebrate the 60th anniversary. This year Australians also acknowledge 200 years of European settlement in this country and so the Symposium is both a Bicentennial and a diamond jubilee event which recognises the impact of trace elements on agricultural development in Australia. In a broader sense, a symposium such as this celebrates, as it reviews, the efforts of all who over the ages have contributed to our knowledge of manganese in soils and plants.
Download or read book Production of Manganese Ferroalloys written by Sverre E. Olsen and published by Tapir Academic Press. This book was released on 2007 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Progress in our knowledge of thermodynamics and physico-chemical factors in manganese ferroalloy production has developed rapidly during the past twenty-five years or so. The authors' intention has been to use this basic knowledge in discussions of industrial manganese ferroalloy production. The book presents the principles and current knowledge of processes in the production of high carbon ferromanganese, silicomanganese and low carbon manganese alloys. The book is intended for professionals working in production, plant design or development. It will also be useful for researchers in industry, universities and research institutes. The book can be used as a textbook for courses in extractive and process metallurgy, and for company in-house courses. Thermodynamics of the slag and metal systems are extensively covered. Computational modelling based on assessed thermochemical databases has made it possible to calculate and present a large number of phase and equilibrium diagrams. These diagrams are useful for easy understanding and analysis of the complex heterogeneous equilibria in the manganese ferroalloy metallurgy. The manganese ferroalloys are mainly produced in electric submerged arc furnaces. Electrical relations are briefly discussed. Supply of raw materials, especially manganese ores and coke, is extremely important for the manganese industry. The book gives the reader appropriate knowledge regarding the selection the best of available raw materials. Environmental issues, including greenhouse gas emissions and climate changes, are of growing concern to ferroalloy producers. Carbon will always be needed as a reducing agent, and consequently emission of CO2 gas is inevitable. The book describes solutions to dealing with pollution problems and gives the latest guidelines for greenhouse gas inventories.
