The first organically templated open-framework metal selenate with a three-dimensional architecture.
A three-dimensional metal selenate of the formula [C2N2H10][La2(SeO4)4(H2O)3].H2O, comprising La2Se4 building units and possessing 12-membered channels, has been prepared in an acidic medium under hydrothermal conditions.
A simple method was developed to speciate inorganic Se in the mg L range using coupled ion chromatography-hydride generation atomic absorption spectrometry. Because of the differences in toxicity and adsorption behavior, determination of the redox states selenite, Se(IV), and selenate, Se(VI), is important. We used anion exchange chromatography to separate Se(IV) and Se(VI) based on differences...
Selenium (Se) biofortification of plants has been recognized as a good strategy to improve the nutritive value vegetables and increase Se daily intake in humans. Identifying most appropriate method enrich is key issue process. We tested technique that produces enriched seedlings for transplant, yet barely modifies conventional cultivation techniques. Lettuce (Lactuca sativa L.) sweet basil (Oci...
Selenium (Se) plays an indispensable role in human nutrition and has been implicated to have important health benefits, including being a cancer preventative agent. While different forms of Se vary in their anticarcinogenic efficacy, Se-methylselenocysteine (SeMSC) has been demonstrated to be one of the most effective chemopreventative compounds. Broccoli (Brassica oleracea var. italica) is kno...
BACKGROUND Selenomethionine, which is the principal dietary form of selenium, is metabolized by the liver to selenide, which is the form of the element required for the synthesis of selenoproteins. The liver synthesizes selenium-rich selenoprotein P (SEPP1) and secretes it into the plasma to supply extrahepatic tissues with selenium. OBJECTIVES We conducted a randomized controlled trial to de...
The scope of the work was to investigate the influence of selenate fertilisation and the addition of symbiotic fungi (mycorrhiza) to soil on selenium and selenium species concentrations in garlic. The selenium species were extracted from garlic cultivated in experimental plots by proteolytic enzymes, which ensured liberation of selenium species contained in peptides or proteins. Separate extrac...
