Intravenous iron therapy is used to treat anemia associated with chronic kidney disease. The chemical structures of parenteral iron agents have not been characterized in detail, and correlations between structure, efficiency of iron delivery, and toxicity via catalysis of oxygen-derived free radical creation remain to be established. In this study, two formulations of parenteral iron have been ...

PURPOSE This study was performed to evaluate the dietary nutrient intake status and hair mineral content of Korean young children. METHODS Fifty-five children who visited Seoul National University Bundang Hospital were divided into three groups by age: infants, toddlers, and preschoolers. The 24-hour recall method was used to collect the food intake data of the subjects. Hair mineral analysis...

In addition to determining the amounts of isolated nutrients required for physiological function and homeostatic control, setting Recommended Di etary Allowances requires a consideration of nutrient bioavailability from foods in common diets. Bioavail ability algorithms, or mathematical models to estimate nutrient bioavailability from different diets, have great appeal to help establish recomme...

Iron is the most abundant trace mineral in the body and is an essential element in most biological systems.1,2 It is likely that iron was essential for developing aerobic life on Earth.3 But iron is toxic to cells in excessive amounts. Acute iron poisoning is common and potentially lethal in dogs, cats, and many other animals. Iron is also a leading cause of unintentional poisoning deaths in ch...

The inhibitory effect of phytate on the bioavailability of iron, zinc and calcium was determined by measuring their molar ratios. A total of 29 food samples consisting of 12 rice and rice products, 5 wheat and wheat products, 5 grains and cereal based products and 7 different popular varieties of cooked rice and rice products were selected. The phytate content was analysed using anion-exchange ...

Iron, copper, zinc, and eight other minerals are classified as essential trace elements because they present in minute in vivo quantities and are essential for life. Because either excess or insufficient levels of trace elements can be detrimental to life (causing human diseases such as iron-deficiency anemia, hemochromatosis, Menkes syndrome and Wilson's disease), the endogenous levels of trac...

Iron is an essential element for all living organisms due to its ubiquitous role in redox and other enzymes, especially in the context of respiration and photosynthesis. The iron uptake and storage systems of terrestrial/higher plants are now reasonably well understood, with two basic strategies for iron uptake being distinguished: strategy I plants use a mechanism involving induction of Fe(III...

For well over 30 y, it has been known that at the absorptive and metabolic levels, minerals, both macro and trace, interact with one another. With the knowledge gained in the same time span, greater insight has been established as to how the stores of a particular mineral may regulate the absorption of that same mineral. Additionally, we have a greater understanding of how the concentrations of...

In this work, a bench-scale process was developed using mineral-processing methods to recover iron from a placer deposit located in Bardaskan, Khorasan-e-Razavi, Iran. The mineralogical studies were performed by X-ray Diffraction (XRD), X-ray Fluorescence (XRF), Electron Probe Micro-Analyzer (EPMA), and an optical microscope. These studies indicated that titanomagnetite, magnetite, and hematite...
