متن کاملDerbyshire Neck and Iodine Deficiency
Goitre and the associated neurological deficits of cretinism and deaf mutism due to iodine deficiency were common in Derbyshire, giving rise to the term Derbyshire Neck. These diseases were most prevalent in the 19th century and earlier, when they had devastating effects in the rural population. Since then they have declined in frequency. However, iodine deficiency disorders are still prevalent...
متن کاملScandium-44: benefits of a long-lived PET radionuclide available from the (44)Ti/(44)Sc generator system.
(44)Ti/(44)Sc radionuclide generators are of interest for molecular imaging. The 3.97 hours half-life of (44)Sc and its high positron branching of 94.27% may stimulate the application of (44)Sc-labeled PET radiopharmaceuticals. This review describes the current status of (44)Ti production, (44)Ti/(44)Sc radionuclide generator development, post-processing of generator eluates towards medical app...
متن کاملDerbyshire Natural Minerogenic Dust and Human Health
Atmospheric aerosols include gases and liquids, as well as solid particles. They include material derived from both oceans and landmass, as well as particles that form within the atmosphere, such as sulfates. Solid particles entrained in the atmosphere by detachment from poorly vegetated surfaces (the process of deflation) include, for example, rock and mineral dust, fine mineral aggregates, fi...
متن کاملScandium(III) complexes of monophosphorus acid DOTA analogues: a thermodynamic and radiolabelling study with (44)Sc from cyclotron and from a (44)Ti/(44)Sc generator.
The complexation ability of DOTA analogs bearing one methylenephosphonic (DO3AP) or methylenephosphinic (DO3AP(PrA) and DO3AP(ABn)) acid pendant arm toward scandium was evaluated. Stability constants of their scandium(iii) complexes were determined by potentiometry combined with (45)Sc NMR spectroscopy. The stability constants of the monophosphinate analogues are somewhat lower than that of the...
