This book was released on 2017-01-31 with total page 448 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.

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.

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.

Book excerpt: Each year, it becomes more apparent that trace elements play an important role in human metabolism. The concept is no longer new. The literature on the subject is voluminous. Dr. Prasad, who has been interested in this field for many years, has undertaken the enormous task of bringing our knowledge together in a comprehensive fashion. This monograph should prove very informative and extremely useful to everyone who is concemed with human disease and with the maintenance of good health. His coverage of the subject is broad. Because ofthe importance of iron, in addition to "trace" elements, in human metabolism and nutrition, a chapter dealing with iron has been included. Maxwell M. Wintrobe, M.D. vii PREFACE It has been known for several decades that many elements are present in living tissues, but it was not possible to measure their precise concentra tions until recently. They were therefore referred to as occurring in "trace" amounts, and this practice led to the use of the term "trace elements." Although techniques now available are such that virtually alI trace elements can be determined with reasonable accuracy, the designation "trace ele ments" remains in popular usage.

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.

Book excerpt: This book provides a comprehensive analysis of biominerals, in particular phosphates and carbonates of calcium. The book begins with a discussion of the theories of solid state chemistry and thermodynamics of ionic solid solutions and applies these theories to show how physiological constituents like sodium, magnesium, carbonate, chloride, fluoride, lead, or strontium influence the formation, stability, and solubility of calcium phosphates. The results of this discussion are then applied to a critical evaluation of data regarding minerals in bone, dentin, and tooth enamel, their formation during growth and turn-over, their stability under physiological conditions and their breakdown under pathological conditions. These principles are also applied to pathological calcifications such as renal calculi, arterial wall calcifications, chondrocalcinosis, dental calculus and salivary stones. A similar approach is used as the authors discuss carbonations such as calcite, dolomite, and aragonite. The book also includes an extensive analysis of the advantageous effects of magnesium supplementation. The wealth of knowledge in this extensive treatise of biominerals is valuable to medical, dental and ecological biologists, as well as scientists and clinicians in the fields of osteoporosis, bone diseases, caries, renal stone disease, parodontology and nutrition.

Available in PDF, EPUB and Kindle. Book excerpt: Although introduction of amino acid chelates in mineral nutrition initially met considerable skepticism and controversy, the greater absorption and bioavailability of amino acid chelated minerals compared to nonchelated minerals have been well-documented for decades. Amino Acid Chelation in Human and Animal Nutrition compiles published chemical, nutritional, and clinical studies with new unpublished research. It interprets the combined data for the first time to explain why the body responds to an amino acid chelate differently than it does to inorganic metal salts. Focusing on digestion, the book follows how chelates are absorbed from the stomach and intestines into the mucosal tissue, their movement from the mucosal tissue into the blood, and uptake into tissue and organ cells. Amino Acid Chelation in Human and Animal Nutrition compares amino acid chelate absorption and metabolism and that of inorganic salts of the same minerals. This book mainly focuses on the ingestion of amino acid metal chelates as a way to optimize mineral absorption, but it also provides a fundamental discussion of chelation chemistry. The author includes his own results, as well as alternate interpretations of the results of numerous studies of animal and human amino acid mineral chelate digestion and absorption. The views published in this book are solely the author’s views and do not reflect the views of his company, Albion Laboratories.

Book excerpt: Trace Elements in Health: A Review of Current Issues presents how some metals affect health, growth, and well-being of man and animals in a variety of ways, when the amounts involved are excessive or deficient. This book discusses the various aspects of trace elements in three points of view. First, the toxicological and beneficial properties are described in eleven chapters. Chapter 1 deals with general toxicological properties, while Chapters 2 to 11 reviews advances in the field of elements that include cadmium, copper, indium, thallium, lead, mercury, molybdenum, selenium, zinc, and transuranic series. The next chapters focus on the genetic effects, health of children, and birth rate problems related to trace elements. Finally, this text concludes with a discussion on the role of trace elements in agriculture, focusing on requirements of plants and animals, consequences of excesses and imbalances of trace elements in soils, and animal diets. This publication is valuable to veterinarians and practitioners of disciplines such as physiology, dietetics, and medicine.
