Cerium dioxide nanoparticles (C(e)O₂ ENPs) are on the priority list of nanomaterials requiring evaluation. We performed in vitro assays on mature mouse oocytes incubated with C(e)O₂ ENPs to study (1) physicochemical biotransformation of ENPs in culture medium; (2) ultrastructural interactions with follicular cells and oocytes using Transmission Electron(More)
This work is an attempt to investigate the chemical stability of 1,N2-propano-2'-deoxyguanosine (pdG-HNE) and 1,N2-etheno-2'-deoxyguanosine (epsilondG) DNA adducts against hydrolysis and upon oxidation reactions. It includes both kinetic issues together with proposed degradation pathways. While both chemicals are stable in the 3.5-9 pH range, the results(More)
This work is an attempt to establish if aromatic nitration processes are always associated with an increase of genotoxicity. We determined the mutagenic and genotoxic effects of Benzene (B), Nitrobenzene (NB), Phenol (P), 2-Nitrophenol (2-NP), 2,4-Dinitrophenol (2,4-DNP), Pyrene (Py), 1-Nitropyrene (1-NPy), 1,3-Dinitropyrene (1,3-DNPy), 1,6-Dinitropyrene(More)
