Guido Haenen is appointed as Editor-in-Chief for the Molecular Toxicology section of the International Journal of Molecular Sciences (IJMS). The Journal aims to rapidly publish contributions that describe the mechanism of toxicity of compounds in animals, humans, or appropriate in vitro models. It is situated at the cutting edge of chemistry and biology and its relation to health. The focus is on the molecule and its interaction with biomolecules, as this will result the actual biological effect. Molecular methods aimed at preventing toxicity or enhancing our understanding of health risk assessment are also of interest. Topics include, but are not limited to: -food, drug and chemical toxicology; -genetic toxicology; -reproductive toxicology; -neurotoxicology; -clinical toxicology; -nanotoxicology; -environmental and ecotoxicology; -computational and predictive toxicology; -food-drug interactions; -idiosyncratic toxicity; -toxins.
