The species distribution of xanthine oxidase [PDF]
1. The distribution of xanthine oxidase in blood and tissues of various animals was studied by means of a radioactive assay capable of detecting 10(-7) unit of enzyme. The method was shown to be applicable to tissues with a high uricase content. 2. Of 16 mammalian species examined, six had low concentrations of xanthine oxidase in the serum. In six non-

Biogeographical ‍distributions of trickster animals
Human language encompasses almost endless potential for meaning, and folklore can theoretically incorporate themes beyond time and space. However, actual distributions of the themes are not always universal and their constraints remain unclear.
