Download or read book Intestinal Absorption of Metal Ions Trace Elements and Radionuclides written by S. C. Skoryna and published by Elsevier. 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 Trace Elements in Human and Animal Nutrition written by E Underwood and published by Elsevier. This book was released on 2012-12-02 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: Trace Elements in Human and Animal Nutrition, Fourth Edition, explores the physiological roles of trace elements in human and animal nutrition. It looks at the needs, tolerances, and interactions of trace elements with each other and with other nutrients and compounds, and it explores how deficient, toxic, or imbalanced intakes of such elements lead to biochemical and pathological changes. It also describes ways of diagnosing and addressing such aberrant intakes of trace elements, along with their principal sources. Organized into 20 chapters, this volume begins with an overview of the nature of trace elements and their mode of action, including iron, copper, molybdenum, cobalt, nickel, manganese, zinc, cadmium, chromium, iodine, selenium, fluorine, mercury, vanadium, silicon, lead, and arsenic. It then discusses the presence of these elements in animal tissues and fluids, along with their metabolism, functions, and toxicity. It also considers other elements, such as aluminum, antimony, barium, boron, bromine, germanium, lithium, rubidium, silver, strontium, tin, titanium, and zirconium. The book concludes with an analysis of the interrelationships among soil, plants, and animals. This book should be a valuable resource for students and chemists.

Available in PDF, EPUB and Kindle. Book excerpt: The major change in the format of the fifth edition is the presentation of the book in two volumes, necessitated by the rapidly increasing knowledge of metabolism, interactions, and requirements of trace elements ... The guiding principle was to present the minimum of results that would serve as a logical foundation for the description of the present state of knowledge. Recent results of research were accommodated by devoting new chapters to the subjects "Methodology of Trace Element Research" and "Quality Assurance for Trace Element Analysis" and by expanding the discussion of lithium and aluminum in separate, new chapters. The first two subjects are of outstanding importance as determinants of future progress. The concern for the quality of analytical data motivated the authors of the individual chapters to review critically and, where necessary, revise analytical data presented in the previous editions. The rapid progress of trace analytical methodology since the mid-1970s has changed what had been accepted as normal for the concentrations of many trace elements in tissues and foods. The new data reflect the present state of the art in trace element analysis, but they may be subject to future revision.

Download or read book Pharmacology of Intestinal Permeation I written by and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 719 pages. Available in PDF, EPUB and Kindle. Book excerpt: The intestine, particularly the small bowel, represents a large surface (in the adult 2 human approximately 200m ) through which the body is exposed to its environment. A vigorous substrate exchange takes place across this large surface: nutrients and xenobiotics are absorbed from the lumen into the bloodstream or the lymph, and simultaneously, the same types of substrate pass back into the lumen. The luminal surface of the intestine is lined with a "leaky" epithelium, thus the passage of the substrates, in either direction, proceeds via both transcellular and intercellular routes. Simple and carrier-mediated diffusion, active transport, pinocytosis, phagocytosis and persorption are all involved in this passage across the intestinal wall. The term "intestinal permeation" refers to the process of passage of various substances across the gut wall, either from the lumen into the blood or lymph, or in the opposite direction. "Permeability" is the condition of the gut which governs the rate of this complex two-way passage. The pharmacologist's interest in the problem of intestinal permeation is twofold: on the one hand, this process determines thebioavailability of drugs and contributes significantly to the pharmacokinetics and toxicokinetics of xeno biotics; on the other hand, the pharmacodynamic effects of many drugs are manifested in a significant alteration of the physiological process of intestinal permeation.
Download or read book Zinc Clinical and Biochemical Significance written by Stephen C. Cunnane and published by CRC Press. This book was released on 2018-01-10 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: In keeping with the etiology theme, it also became apparent that the clinical aspects needed to be strictly separated from the animal aspects of zinc metabolism, a separation that has never previously been attempted. Although this division, like the separation of primary from secondary zinc depletion, may be somewhat arbitrary, it is the author‘s impression that current knowledge of the truly clinical aspects of zinc metabolism is too often confused with its effects in animals. The two will frequently be similar, but not always. In this book, therefore, animal studies are considered in part 2 (Biochemistry. Only a handful of references to animal studies has been included in part 1 (Clinical). The purpose of this separation is to clearly distinguish animal from human, experimental from clinical. Too many of the animal studies have involved severe and prolonged zinc deficiency or other exaggerated nutritional conditions that cannot be realistically applied in the clinical setting. Furthermore, animal studies are mainly or primary (dietary) zinc depletion, whereas in humans, secondary zinc depletion is more prevalent and has a more diverse etiology.
Download or read book Molecular Biology of Metal Homeostasis and Detoxification written by Markus J. Tamás and published by Springer Science & Business Media. This book was released on 2006-07-07 with total page 519 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the challenges faced by every cell as well as by whole organisms is to maintain appropriate concentrations of essential nutrient metals while excluding nonessential toxic metals. Toward that end, all organisms have developed mechanisms for metal homeostasis and detoxification to maintain metal levels within physiological limits. This book brings together current knowledge of the molecular basis of metal homeostasis and detoxification in various eukaryotic model systems, including yeasts, plants, and mammals. It focuses on the cellular systems controlling metal transport, intracellular distribution, and immobilization as well as on systems regulating metal-dependent transcription. In addition to environmental aspects (including phytoremediation), the book treats the pathophysiology of metal deficiency and overload in relation to disease.

Download or read book Principles of Animal Extrapolation 1991 written by Edward J. Calabrese and published by CRC Press. This book was released on 2017-11-22 with total page 617 pages. Available in PDF, EPUB and Kindle. Book excerpt: Principles of Animal Extrapolation addresses the conceptual basis for animal extrapolation and provides an abundance of documentation that illustrates how these principles may be applied in the selection of the more appropriate models and in the interpretation of toxicological studies. The book analyzes and documents each specific biological cause of interspecies differences in susceptibility to toxic agents, including differences in absorption, gut flora, tissue distribution, metabolism, mechanisms and efficiencies of repair, and excretion. The problem of the heterogenicity of the human population is addressed through several chapters that assess the availability and prospects of developing predictive animal models for normal humans, as well as selected potential high-risk groups. Other topics presented in this book include the biological basis of regulatory actions involving attempts to extrapolate from exceptionally high exposure levels to realistic values, especially carcinogens; an assessment of genotoxicity tests, their ability to predict carcinogenicity in whole animals, and the manner in which they should be used by regulatory agencies; birth defects; and predicting the risk of human teratogenesis. Principle of Animal Extrapolation is essential for environmental toxicologists. It also provides valuable information to biomedical scientists (especially those involved in drug development and testing) and regulatory personnel in agencies such as the EPA, the OSHA, the NIOSH, and the FDA.
Download or read book Physiologic and Chemical Basis for Metal Toxicity written by B. Venugopal and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our purpose is to provide understanding for appropriate use of metals in a technical society. Knowledge of metal toxicity is needed for the preven tion, prediction, diagnosis, and therapy of adverse reactions from excess metals in mammals. Metal Toxicity in Mammals is presented in two volumes. Volume 1, Physiologic and Chemical Basis for Metal Toxic ity, provides the basis for understanding the toxic actions of metals recorded in Volume 2, Chemical Toxicity of Metals and Metalloids. The details and bases for many concepts summarized in Volume I are given, with appropriate references, in Volume 2. Thus, references for specific items in Volume 2 are not generally given in Volume 1. The authors reviewed the known toxicity of several heavy metals in anticipation of their use as multinutrient markers for NASA. As more and more metals were considered, the need for a complete review became obvious. This treatise supplants onerous searches of metal-toxicity litera ture up to 1975 and reviews the toxicity of all the metals of the periodic table on the basis of available relevant data. Books on pharmacological, nutritional, medical, veterinary, or industrial toxicity contain information about selected metals. More complete data about metals of public concern, such as mercury, lead, and cadmium, may be found in numerous books and reviews. The reader should refer to general texts and basic reference works, when specific references are not given, for general information.
