Relationships between non-avian theropod dinosaurs and extant and fossil birds are a major focus of current paleobiological research. Despite extensive phylogenetic and morphological support, behavioural evidence is mostly ambiguous and does not usually fossilize.

An high-pressure liquid chromatographic method was used to measure allopurinol and oxipurinol in plasma and urine in 6 healthy volunteers after a single intravenous or oral dose of allopurinol. The influence of coadministered benzbromarone and hydrochlorothiazide on the pharmacokinetics of allopurinol and oxipurinol was also investigated. After intravenous injection of allopurinol 300 mg the plasma disappearance was biexponential, with a mean distribution half-life of 2.

Several strains, however, are known to nodulate rj1 plants in vermiculite or sand culture. Pure broth cultures of one of these strains (61 NalR) and a strain producing the typical non-nodulating response with rj1 (I-110 ARS) were mixed and used as inoculum on Clark rj1 soybeans in a growth chamber experiment.
