Angewandte Chemie, Volume 138, Issue 31, 27 July 2026.Proposed mechanism for Fe3+ transport from the FoC (sites 1 and 2) of human H‐chain ferritin following oxidation of the di‐Fe2+ form. Glu61, aided by the flexibility of its sidechain, plays a key role in coordinating Fe3+ at three sites (3, 4 and 5) that mark out the transit route.

Micronuclei induction in Rana catesbeiana tadpoles by the pyrethroid insecticide lambda-cyhalothrin
Genetics and Molecular Biology, 2003 Pyrethroid lambda-cyhalothrin genotoxicity was evaluated using the micronucleus test in Rana catesbeiana tadpoles. The effects of concentration and exposure time on the micronuclei frequency were studied in blood smears obtained from tadpoles exposed to ...
