Summary: The comet assay is used to assess DNA damage in tissues and biological samples. This study found that storage time had varying effects on DNA damage levels in PBMCs and WB samples, with significant increases observed in WB samples stored for over 6 months. WB samples showed higher levels of DNA damage compared to PBMCs.

Summary: Zebrafish have become a popular model for assessing the genotoxicity of pollutants due to their orthologous genes and involvement in repair pathways. Comet assay is the main technique used in these studies, but standardization is needed for better interpretation and comparisons. Understanding repair mechanisms in zebrafish subjected to DNA damage is essential for further research on genotoxic effects caused by pollutants.

Summary: Pollution from mining activities can cause genotoxic damage to bats, particularly in species like Carollia perspicillata and Glossophaga soricina. High levels of elements such as Mn, Cr, Pb, and Zn were found in water samples from the mining area. The study suggests that bats in mining areas are susceptible to increased DNA damage, similar to what has been observed in other species.

Summary: Occupational exposure to pesticides in farmers results in significant DNA damage, showing a notable impact and variability in the studies. Smokers who are occupationally exposed to pesticides have slightly reduced DNA damage compared to non-smokers, indicating some genetic toxicity. The study demonstrates a higher risk of occupationally exposed rural workers developing related diseases due to the genotoxic effect of pesticides.

Summary: This study found that cyprodinil and thiacloprid exposure can lead to increased DNA damage risk in zebrafish, as demonstrated by comet assay. These pesticides were identified as genotoxic agents that require further investigation.

Summary: This study evaluated the effect of pesticides on genetic damage to agricultural workers in Los Reyes, Michoacan, Mexico. The results showed that pesticide use poses a risk of genetic damage to agricultural workers, but measures can be taken to reduce this risk.

Summary: By conducting nose-only inhalation tests on mice, we found that the air concentration of molybdenum disulphide particles has no observed adverse effect on body weight gain and genotoxicity below 13mg/m³, while the effects on respiratory function suggest this level as the lowest observed adverse effect concentration.

Summary: Habitat loss and fragmentation pose significant threats to biodiversity. The use of bioindicators can provide insight into the health of the environment. A study conducted in agricultural areas found higher genotoxic damage in bats compared to a control area.

Summary: The comet assay is widely used in basic research, genotoxicity testing, and human biomonitoring. The study found that DNA damage exceeding 20-30% tail DNA caused more than 50% of cells to die, with etoposide causing slightly more cell death than H2O2 or MMS. Cells showed some repair capacity for DNA damage within a few hours after substance removal.

Summary: DNA damage is a common cellular feature in cancer and neurodegenerative disease, but there is a lack of fast and accurate methods for quantifying DNA damage. The comet assay is a biochemical tool that measures DNA damage based on the migration of broken DNA strands towards a positive electrode, creating a quantifiable 'tail' behind the cell. However, the analysis of comets using existing open-source algorithms is time-consuming and requires manual curation. To overcome these limitations, we developed AutoComet, an open-source algorithm that automates comet segmentation and quantification of tail parameters. AutoComet significantly improves segmentation accuracy and reduces analysis time over ten-fold, providing a fast and unbiased method for quantifying DNA damage.

Summary: The study evaluated the genotoxic effect of endosulfan on grass carp blood, finding that exposure to this pesticide led to significant DNA damage in a time- and dose-dependent manner. As endosulfan demonstrated severe genotoxic effects on Ctenopharyngodon idella, the study recommends that its use be controlled and monitored by government authorities to prevent further harm to ecosystems.

Summary: This study evaluated the cytotoxic and genotoxic effects of biosynthesized silver nanoparticles on breast cancer and umbilical vein endothelial cells. The results showed that the synthesized silver nanoparticles exhibited cytotoxic and genotoxic effects on breast cancer cells, but had no significant effects on normal cells.
