Comment iT HC GPE; The methods used in this study are referenced to prior work by the same author which explains why some of the information (controls, organisms/replicate) is not explicitly stated in the paper itself. The related previous work is therefore reviewed together. Group: Poly(oxy-1,2-ethanediyl), a-hydro-?-hydroxy- [25322-68-3]
