A Theoretical Model for Utilizing Mammalian Pharmacology and Safety Data to Prioritize Potential Impacts of Human Pharmaceuticals to Fish
TLDR
A model has been developed to utilize the information from mammalian pharmacology and toxicology studies to evaluate the potential for chronic receptor mediated responses in fish and to strengthen the applicability of this approach as a viable tool for prioritizing research initiatives that examine the potential impact of pharmaceuticals on fish.

The fate of benzoic acid in various species.
TLDR
It appears that the hedgehog and ferret are like the dog in respect to their metabolism of benzoic acid, and the Indian fruit bat produced only traces of hippuric acid and possibly has a defect in the glycine conjugation of benzosic acid.

Metabolism of [14C]methamphetamine in man, the guinea pig and the rat
TLDR
The main reaction in the rat was aromatic hydroxylation, in the guinea pig demethylation and deamination, whereas in man much of the drug, possibly one-half, was excreted unchanged, and Marked species differences in the metabolism of methamphetamine were observed.
