Relative Bioavailability of Inorganic and Natural Selenium
Introduction Research efforts have identified groups of people with low selenium intakes and presumed selenium deficiency based on low blood selenium levels. Inhabitants of New Zealand [1], Finland [2], and China [3] often have low blood selenium. Individuals with therapeutic diets low in selenium [4], people undergoing parenteral administration [5] and alcoholics with cirrhosis [6] can also be...
متن کاملInfluence of Inorganic and Organic Selenium Sources on Broiler Performance and Meat Quality
An experiment was carried out to evaluate and compare the effects of organic and inorganic selenium (Se) sources on broiler male birds (Ross 308). Uniform broiler male chicks divided in to five groups with six replicates were fed with either normal feed (without supplemental Se, negative control), 0.25 ppm of inorganic Se, 0.5 ppm of inorganic Se, 0.25 ppm of inorganic Se + 0.25 ppm of organic ...
متن کاملTrace mineral changes in response to organic and inorganic selenium supplementation
Twenty-one Lori–Bakhtiary sheep were randomly allocated into 3 groups to compare the effects of oral selenium nano particles (Se NPs) and sodium selenite (Na-Se) supplementation on serum selenium, copper, zinc, molybdenum, manganese and cobalt concentration. Groups 1 and 2 orally received Se NPs and Na-Se (1 mg/kg) for 10 consecutive days, respectively ...
متن کاملDetermination of Organic and Inorganic Selenium Species Using HPLC-ICP-MS Application
A methodology based on coupling isocratic high-performance liquid chromatography (HPLC) and inductively coupled plasma mass spectrometry (ICP-MS) with optimized collision/reaction cell conditions has been developed for the simultaneous analysis of organic and inorganic selenium species in natural water samples. Selenium concentrations found in total and speciation analysis of a number of water ...
متن کاملChemical characterization of organic carbon dissolved in natural waters using inorganic adsorbents.
Dissolved organic carbon (DOC) in water samples from Lake Biwa was chemically characterized by two inorganic adsorbents with completely different surface characteristics. The two adsorbents were HIO (hydrous iron oxide) and SG (silica gel). Solutions of reference standard materials were analyzed concerning their adsorption behavior to HIO and SG for bovine serum albumin (BSA), fulvic acid extra...
