Micronucleus assay in genotoxicity assessment

open access: yesActa fytotechnica et zootechnica, 2016
Three different pesticide formulations were tested for micronuclei production and cell cycle arrest. Micronucleus test represents a suitable method for assessing chromosome damage because both chromosome breakage (clastogenicity) and chromosome loss (aneugenicity) can be measured simultaneously.

Titanium Detected in Liver, Kidney, Spleen, and Intestine Is Not Related to Dose, Time, or Route of Exposure to Titanium Dioxide: A Systematic Review

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Titanium dioxide (TiO2), used as a food additive (labeled E171 in Europe), was withdrawn from the European market in 2022. The E171 toxicity mechanism involves its uptake, oxidative stress, DNA damage, and inflammation. It has been hypothesized that the TiO2 accumulation nanoparticles (NPs) or E171 triggers tissue damage, and some studies have
