A facile method for the preparation of highly active and enantioselective yttrium precatalysts for asymmetric hydroamination of gem-disubstituted aminoalkenes, from the combination of YCl(3) or YCl(3)(THF)(3.5) with ligand (R)- and n-BuLi is described.
The efficacy of diethylenetriaminepentaacetate calcium trisodium (CaNa(3)DTPA) in a dose of 34.7 micromol kg(-1) as a function of its route of administration was investigated in rats with a puncture wound contaminated by (90)Y-chloride at a concentration of 2.55 MBq kg(-1).
Negatively charged globular proteins in solution undergo a condensation upon adding trivalent counterions between two critical concentrations C and C, C <C. This reentrant condensation behavior above C is caused by short-ranged electrostatic interactions between multivalent cations and acidic residues
