The class of carbazoles includes compounds with high biological activities and broad spectra of action. PLX01107 and PLX01008 are xenomycins, a new subclass of antimicrobial carbazole derivatives demonstrating strong antifungal activity in vitro. We performed three tests, a bacterial reverse mutation assay (Ames test), in vitro cytokinesis-block micronucleus assay, and chromosome aberration test in...
Titanium dioxide nanoparticles (TiO2-NPs) and zinc oxide nanoparticles (ZnO-NPs) are often used in sunscreens and other consumer products due to their photoprotective properties. However, concern exists regarding them possibly causing cyto- and genotoxic effects. The aim of this study was to assess cyto- and genotoxicity of these nanomaterials after single or combined exposure. For this purpose, a...
Polybrominated diphenyl ethers (PBDEs), a class of brominated flame retardants, have been widely used as additive flame retardants. Recently, the use of brominated flame retardants has been restricted or prohibited under various legislative acts because of the persistence, bioaccumulation potential, and toxicity of these compounds. However, there are also additional concerns regarding environmental...
2-Nitroanisole (2-NA) is used in the manufacturing of azo dyes and causes cancer, mainly in the urinary bladder. Previous in vivo genotoxic data seems to be insufficient to explain the mechanism through which 2-NA induces carcinogenesis, and several bladder carcinogens were reported to induce oxidative DNA damage. Thus, we examined the potential induction of oxidative DNA damage by 2-NA using bacterial...
Cadmium is a toxic heavy metal with many industrial and commercial uses resulting in widespread environmental pollution. Exposure to cadmium occurs occupationally, through tainted food, tobacco leaves, and the environment. Cadmium exposure has been linked to neurological and respiratory problems and cancer. Past studies have examined cytotoxicity, DNA damage, micronuclei formation, or mutagenesis...
Chronic obstructive pulmonary disease (COPD) is a type of obstructive lung disease characterized by long term poor airflow which worsens over time. It is considered to be one of the top five chronic diseases of the world in terms of morbidity and mortality. Genetic variability has been found to contribute to the development of COPD. Although association between gene polymorphisms in EPHX1 and TNF-a...
