The present study was aimed to evaluate the antigenotoxic effect of Mosinone-A on 7,12-dimethylbenz[a]anthracene induced genotoxicity. The frequency of micronucleated polychromatic erythrocytes [MnPCEs], chromosomal aberrations [CA], DNA damage (comet assay) as cytogenetic markers and the status of lipid peroxidation byproducts, antioxidants and phase II detoxification agents were used as biochemical markers to assess the antigenotoxic effect of Mosinone-A on DMBA induced genotoxicity. A single intraperitoneal injection of DMBA (30 mg/kg b.wt) to golden Syrian hamsters, resulted in marked elevation in the frequency of MnPCEs, aberrations in the chromosomal structure were found in bone marrow and DNA damage (comet assay) was found in blood cells and altered level of lipid peroxidation, antioxidants, and phase II detoxification agents. Oral pretreatment of Mosinone-A (2 mg/kg b.wt) for 5 days to DMBA treated animals significantly reduced the frequency of MnPCEs, chromosomal abnormalities such as chromosomal break, gap, minute, fragment, DNA damage and reversed the status of biochemical variables. Our results thus demonstrated the antigenotoxic effect of Mosinone-A on DMBA induced genotoxicity in male golden Syrian hamsters.

Diesel exhaust particles (DEPs) are atmospheric pollutants associated with adverse health effects. In response to their impact, natural gas (NG) has emerged as a promising alternative fuel due to its cleaner combustion. Although the cytotoxicity and genotoxicity of DEPs from diesel or NG engines have been extensively studied, the impact of dual natural gas-diesel systems remains unexplored.

The current study aimed to detect the mutagenic impacts of aflatoxin B1 (AFB1), which is produced by Aspergillus group fungi, via a high-plant genotoxicity test. Different durations of treatment (3 h, 6 h, and 12 h) were used to treat the Vicia faba root tips with varying concentrations of Aflatoxin B1 (AFB1) following the approved protocol for plant assays published by the International Program on Chemical Safety (IPCS) and the World Health Organization (WHO). The data obtained indicated that AFB1 not only has the ability to induce various alterations in the process of mitosis, ranging from increasing to decreasing mitotic and phase indices but also leads to many mitotic aberrations.

Cadmium (Cd) is among the most ecologically harmful heavy metals. The purpose of this work was to identify the biologically active components in dried oleo-resin-gum of extract (FAE) and assess their preventive efficacy against oxidative damage caused by Cd in rats. The biologically active components were identified using HPLC and GC-MS.

Scanty information is available about the deleterious effects of Pymetrozine on fish especially bighead carp. Hence, the current study investigated chronic toxicological effects of pymetrozine in bighead carp.

Terrestrial and aquatic ecosystems face various chemicals that might induce acute and/or long-term harm. To assess these impacts, ecotoxicological bioassays are essential. However, bioassays using animals, particularly mammals, are costly, time-consuming, and raise ethical concerns.
