This book was released on 2013-10-22 with total page 466 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intestinal Absorption of Metal Ions, Trace Elements, and Radionuclides focuses on the transport of metal ions across biological membranes. The selection first discusses fundamental considerations of ion transport across biological membranes, including passage of ions through the pores of gels or membranes; mobilities of organic and inorganic ions in water; and complexing of alkali metal ions. The text then focuses on ion transport across membranes of high ionic selectivity and transmissivity and their uses in model studies; model systems for transcellular active transport; and detection and implications of active salt transport across biological membranes. The book takes a look at the intestinal absorption of sodium, calcium, and potassium, including sodium and potassium transport in the intestines; use of radioisotopes to assess intestinal flux of calcium in humans; and calcium and structure of cell membranes. The intestinal absorption of zinc, cobalt, and strontium and absorption of copper from the gastrointestinal tract are underscored. The selection is a recommendable source of data for readers interested in the transport of metal ions across biological membranes.

Download or read book Metal Chelation in Medicine written by Robert Crichton and published by Royal Society of Chemistry. This book was released on 2016-10-26 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metal chelators are emerging as versatile tool with many medical applications. Their versatility allows them to be used in chelation therapy for treating diseases caused by toxic and heavy metal poisoning, chelating agents are capable of binding to toxic metal ions to form complex structures which are easily excreted from the body removing them from intracellular or extracellular spaces. In addition, metal chelators can also be applied as contrast agents in MRI scanning. Metal Chelation in Medicine provides a clear and timely perspective on the role of chelating agents in the management of metal intoxications and storage diseases. Written by leaders in the field of chelators, this publication is at the cutting-edge of the subject. It covers a broad range of topics such as the use of metal chelators in non-invasive assessment of brain iron overload, and the treatment of systemic iron overload and neurodegenerative diseases. As such it is particularly valuable to clinicians treating metal poisonings and metal storage diseases. However, it is also a useful text for researchers, industry professionals and university students with a specific interest in medicinal chemistry, chelation, metal ions, imaging and non-invasive techniques.

This book was released on 2013-03-09 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: The explosion of information published these days in the primary research literature represents in some ways a substantial barrier to the new investigator or researcher crossing over traditional boundaries between fields. Commonly held beliefs and practices of the field's cognoscente often are poorly understood or appreciated by researchers even in closely related areas. Although review articles offer some relief from this situation, a more complete overview of a subject can often only be had through the forum of a book. The desire to better understand factors influencing mineral absorption in the intestines provided the impetus for us to organize the symposium Mineral Absorption in the Monogastric GI Tract: Chemical, Nutritional and Physiological Aspects, held June 9-10, 1988 in Toronto, Canada, as part of the 195th National Meeting of the American Chemical Society and the Third North American Chemical Congress. The criteria for inviting participants was that they be currently active in research pertinent to mineral absorption, be publishing results of their investigations and willing to participate in a forum designed to present diverse considerations of mineral absorption to a multidisciplinary audience. The individual chapters are mixtures of reviews and original research.
Download or read book Chelation Therapy in the Treatment of Metal Intoxication written by Jan Aaseth and published by Academic Press. This book was released on 2016-04-18 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chelation Therapy in the Treatment of Metal Intoxication presents a practical guide to the use of chelation therapy, from its basic chemistry, to available chelating antidotes, and the application of chelating agents. Several metals have long been known to be toxic to humans, and continue to pose great difficulty to treat. These challenges pose particular problems in industrial settings, with lead smelting known to be associated with hemopoietic alterations and paralyses, and the inhalation of mercury vapor in mercury mining being extremely detrimental to the central nervous system. Clinical experience has demonstrated that acute and chronic human intoxications with a range of metals can be treated efficiently by administration of chelating agents. Chelation Therapy in the Treatment of Metal Intoxication describes the chemical and biological principles of chelation in the treatment of these toxic metal compounds, including new chelators such as meso-2,3-dimercaptosuccinic acid (DMSA) and D,L-2,3-dimercapto-1-propanesulfonic acid (DMPS). Presents all the current findings on the potential for chelation as a therapy for metal intoxication Presents practical guidelines for selecting the most appropriate chelating agent Includes coverage on radionuclide exposure and metal storage diseases Describes the chemical and biological principles of chelation in the treatment of toxic metal compounds
Download or read book Metallothioneins and Related Chelators written by Astrid Sigel and published by Royal Society of Chemistry. This book was released on 2009 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chapters 3 to 5 give an account of bacterial MTs, MTs in yeast and fungi, and MTs in plants. Most astonishingly, the MTs of bacteria and plants contain next to cysteine also histidine residues and thus, metal ions are not only sulfur- but also imidazole-coordinated which gives rise to zinc finger-like structures. Remarkably, yeast and fungal MTs are Cu(I) rather than Zn(II) or Cd(II) binding proteins. Next, Chapters 6 through 9 discuss the MTs of dipteran insects, including the model organism Drosophila melanogaster, earthworms and nematodes, as well as echinoderms, crustaceans, molluscs, and fish. Actually, aquatic animals, both vertebrates and invertebrates, have the potential to be used for monitoring metal contamination in aquatic ecosystems. Interestingly, in Chapter 9 the remarkable speculation is presented that under chronic natural exposure conditions the animals establish a trade-off between the "cost" of detoxifying non-essential metals and the "cost" of allowing some of these metals to spill over onto metal-sensitive sites. This contrasts with laboratory experiments involving aquatic animals, where the toxicity of non-essential metals normally exhibits a threshold response: at low exposure concentrations the organisms can detoxify the incoming metal and thus, tolerate the exposure, whereas at concentrations above the threshold, the detoxification mechanism is no longer able to protect the organism completely.

Download or read book Protein Nutrition and Mineral Absorption written by Raul A. Wapnir and published by CRC Press. This book was released on 1990-09-25 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents information regarding the mechanisms of protein absorption under normal and pathologic conditions, in addition to reviewing changes that occur at various stages of life. General modifiers of intestinal absorption, such as the processing of foods, the nutritional status of the individual, and disease, are explored with reference to both proteins and minerals. Inorganic macronutrients, namely calcium, magnesium and phosphorus, are discussed in relation to protein ingestion. The book also explores the concept of essential trace elements (e.g., iron, zinc, copper, and iodine) and their link to protein sufficiency. The relationship of ultratrace elements with the content of proteins in food is examined, and the book offers a fresh view of the role of certain elements, particularly zinc, on the conformation of proteins linked to DNA, hormone receptors, and gene products. Protein Nutrition and Mineral Absorption is packed with 2,300 references, 100 figures and graphs, plus 25 tables. Nutritionists and physicians will find this book to be an invaluable reference source for rationalizing nutritional interventions and diet modifications for their patients.
