Pre-transplant residual diuresis and oxalic acid concentration influence kidney graft survival. [PDF]

PLoS ONE
Background and hypothesisOxalic acid, a toxic metabolic end product, accumulates when kidney function deteriorates. Apart from its direct tubulotoxicity, it crystallizes at concentrations above 30-40 µmol/L.

2-Aminobenzoxazole–oxalic acid (2/1) [PDF]

IUCrData
In the title compound, 2C7H7N2O+·C2O42−, proton transfer from oxalic acid to the N atom of the heterocycle has occurred to form a 2:1 molecular salt. In the extended structure, N—H...O hydrogen bonds link the components into [100] chains, which feature ...
