The genotoxic effects of the fungicide afugan were analysed by measuring chromosomal aberrations (CAs), sister chromatid exchange (SCE) and micronuclei (MN) in cultured human peripheral lymphocytes. Concentrations of 2.5, 5, 10 and 20 microg/ml of afugan were used during 24 and 48 h. Afugan significantly increased the frequency of CAs at 5, 10 and 20(More)
This study was carried out to investigate the efficacy of PGF(2alpha) for oestrus synchronization (ES) in Awassi ewes to which were administered the progestagen-PMSG combination, and to evaluate the effect of the exogenous GnRH administration immediately after the artificial insemination (AI) on their pregnancy rate and lambing performance during the(More)
Clastogenic properties of the food additive citric acid, commonly used as an antioxidant, were analysed in human peripheral blood lymphocytes. Citric acid induced a significant increase of chromosomal aberrations (CAs) at all the concentrations and treatment periods tested. Citric acid significantly decreased mitotic index (MI) at 100 and 200 mug ml(-1)(More)
Beauvericin, a naturally occurring contaminants of food and feeds, has been implicated in several mycotoxicoses; however, there is little information on its genotoxicity. Therefore, the genotoxic and cytotoxic effects of beauvericin in in vitro cultures of human lymphocytes were investigated with chromosome aberrations (CAs), sister-chromatid exchanges(More)
Mycotoxins are fungal secondary metabolites that can be found in contaminated food and feed. There is some evidence to suggest that certain mycotoxins may be mutagenic. Here, we investigate the genotoxicity of the mycotoxin moniliformin (MON) (3-hydroxycyclobut-3-ene-1,2-dione) in human peripheral blood lymphocytes using chromosomal aberration (CA),(More)
The organophosphorous insecticide acephate was tested for its ability to induce in vitro cytogenetic effect in human peripheral lymphocytes by using the chromosomal aberrations (CAs), sister chromatid exchange (SCE) and micronuclei (MN) assay. The level of nuclear DNA damage of acephate was evaluated by using the comet assay. Concentrations of 12.5, 25, 50,(More)
The aim of this study was to investigate the genotoxic risk to workers occupationally exposed to coal combustion products in Afsin-Elbistan A power plant, located in south-eastern Turkey. We analysed chromosomal aberrations (CAs), polyploidy, sister-chromatid exchanges (SCEs), and micronuclei (MN) in 48 male workers without a history of smoking, tobacco(More)
In this study, possible genotoxic effects of zinc oxide (ZnO) nanoparticles were investigated in cultured human peripheral lymphocytes by using chromosome aberrations and micronucleus assays (MN). For this purpose, the cells were treated with ZnO (1, 2, 5, 10, 15 and 20 μg/mL) for 24 and 48 h. In this research, four types of chromosome aberrations were(More)
Tri-allelic patterns are genotyping irregularities which can be encountered during routine short tandem repeat (STR) profiling in forensic genetic laboratories. Tri-allelic patterns can be classified into two types based on the relative fluorescent intensities of their three component alleles [1]. In the type 1 pattern, the component alleles have unequal(More)
The genotoxic effects of the antifungal drug fluconazole (trade name triflucan) were assessed in the chromosome aberration (CA) test in mouse bone-marrow cells in vivo and in the chromosome aberration, sister chromatid exchange (SCE) and micronucleus (MN) tests in human lymphocytes. Fluconazole was used at concentrations of 12.5, 25.0 and 50.0 mg/kg for the(More)
