Wool or hair fibre is a metabolically dead material after it has left the epidermis. During growth the fibre in the root is a metabolically very active organ, which is highly influenced by the health status of the living being. Arsenic is one of the elements that is easily taken up by the cells of the root and stored in the fibre afterwards. Here we show that arsenic can quantitatively be extracted...
Several sample extraction techniques have been evaluated in order to obtain highest selenium (Se) extraction efficiency in two types of selenium-enriched plants (Allium sativum and Brassica juncea). Three extracting solutions have been studied for this purpose: 0.1M HCl, 25mM ammonium acetate buffer (pH 5.6) and protease in aqueous solution. In each case, the effect of the ultrasonic probe during...
Arsenite (As(III)) has been considered as a human carcinogen associated with many human cancers especially skin cancer. Elucidation of the transformed species of As(III) during its metabolism in cells is beneficial for evaluation of its bioeffect. In this work, a hyphenated method of reversed phase ion pair high performance liquid chromatography - inductively coupled plasma mass spectrometry (RP-IP-HPLC-ICP-MS)...
