Disease relevance of selenium

 

Psychiatry related information on selenium

  • On the basis of inductively coupled plasma/mass spectroscopic analyses, corroborated by operant behaviour and locomotor activity investigations, an orally-active phenylaminoalkyl selenide with restricted CNS permeability was successfully developed [6].
  • 1. Selenium status was investigated in patients with chronic renal failure, with special regard to its relations to the dialysis treatments, dietary habits and clinical signs of atherosclerosis [7].
  • To determine the uptake capacity and long-term stability, hydrocalumite solid solutions between chromate/selenate and hydroxyl were synthesized over a reaction time of more than one year [8].
 

High impact information on selenium

  • This Account focuses on recent developments of the chemistry of metal thio- and selenocarboxylates in our laboratory and potential use of some of these compounds as single-source precursors for making metal sulfide and selenide bulk materials, thin films, and nanoparticles [9].
  • A labile selenium donor compound monoselenophosphate is synthesized from selenide and ATP by selenophosphate synthetase (SPS) [10].
  • E-Se rhodanese was stable in the presence of excess GSH at neutral pH at 37 degrees C. E-Se rhodanese could effectively replace the high concentrations of selenide normally used in the selenophosphate synthetase in vitro assay in which the selenium-dependent hydrolysis of ATP is measured [11].
  • The dependence of reaction velocity on ATP concentration shows sigmoidal kinetics, whereas dependence on selenide concentration obeys Michaelis-Menten kinetics indicating a Km value of 46 microM for selenide [5].
  • We have reconstituted apo-aconitase with iron and selenide to obtain Fe4Se4 aconitase [12].
