Mitotic clustering of pulverized chromosomes from micronuclei [PDF]
Complex genome rearrangements can be generated by the catastrophic pulverization of missegregated chromosomes trapped within micronuclei through a process known as chromothripsis1–5. As each chromosome contains a single centromere, it remains unclear how

ABSTRACT The extensive use of pesticides in modern agriculture has raised increasing concerns regarding the potential biological effects of repeated exposure to pesticide residues and commercial formulations. Mancozeb is a widely used ethylene‐bis‐dithiocarbamate fungicide; however, information on its hematological and genotoxic effects following ...

Dual Genotoxic and Antigenotoxic Effects of 3‐Benzoylcoumarins in Mammalian Cells
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 ...

DNA replication occurs in all lamina positive micronuclei, but never in lamina negative micronuclei [PDF]
A micronucleus is a small nucleus-like structure found in the cytoplasm of dividing cells that suffered from genotoxic stress. It is generally hypothesised that micronuclei content is eventually lost from cells, though the mechanism of how this occurs is unknown.

Cytotoxic and Genotoxic Effects in Buccal Cells of Sandstone Quarry Workers
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 ...

Radiation-induced chromosomal aberrations represent an early marker of late effects, including cell killing and transformation. The measurement of cytogenetic damage in tissues, generally in blood lymphocytes, from patients treated with radiotherapy has ...

Ionic liquids: structure–toxicity relationships, predictive toxicology, and sustainable design
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.
