Dual Genotoxic and Antigenotoxic Effects of 3‐Benzoylcoumarins in Mammalian Cells
Journal of Applied Toxicology, EarlyView.ABSTRACT Coumarins are phenolic compounds widely recognized for their diverse pharmacological activities and have attracted increasing attention as potential chemopreventive agents. In the present study, four known 3‐benzoylcoumarin derivatives [(1), (2), (3), and (4)] were evaluated for their cytotoxic, mutagenic, and antigenotoxic effects in Chinese ...

De Novo Small Supernumerary Marker Chromosomes Arising From Partial Trisomy Rescue
Frontiers in Genetics, 2020 Small supernumerary marker chromosomes (SMCs) are rare cytogenetic abnormalities. De novo small SMCs, particularly those combined with uniparental disomy (UPD), are assumed to result from incomplete trisomy rescue.

Cytotoxic and Genotoxic Effects in Buccal Cells of Sandstone Quarry Workers
Journal of Applied Toxicology, EarlyView.ABSTRACT Mineral extraction poses significant occupational health risks, particularly from respirable crystalline silica exposure. Sandstone quarrying generates substantial dust, yet evidence of its genotoxic effects remains limited. This study investigated cytogenotoxic damage in sandstone quarry workers from southern Brazil using the buccal ...

Ionic liquids: structure–toxicity relationships, predictive toxicology, and sustainable design
Journal of Chemical Technology &Biotechnology, EarlyView.Abstract Ionic liquids (ILs) have often been described as green alternatives to conventional solvents because of their negligible vapor pressure and highly tunable properties. However, low volatility does not necessarily translate into environmental safety, as their biological and ecological effects are strongly influenced by molecular structure.
