Micronucleus of Epistylis [PDF]

Nature, 1946
WHILE studying the cytology of species of Epistylis, it was noticed that the nuclear apparatus of this ciliate presented certain interesting features. The macronucleus of Epistylis is a large and band-shaped body, staining deeply with all nuclear stains, and especially with Feulgen.

Application of image-recognition techniques to automated micronucleus detection in the in vitro micronucleus assay

Genes and Environment
Background An in vitro micronucleus assay is a standard genotoxicity test. Although the technique and interpretation of the results are simple, manual counting of the total and micronucleus-containing cells in a microscopic field is tedious.

Validation of the micronucleus-centromere assay for biological dosimetry

Genetics and Molecular Biology, 2000
The micronucleus assay is frequently used for purposes of biological dosimetry. Due to high interindividual variability in the spontaneous frequency of micronuclei, its sensitivity in the low dose region is poor.

Integrated Biomarker Assessment of Bifenthrin, Chlorpyrifos and Endosulfan Toxicity in Indigenous Carps (Catla catla and Labeo rohita): Oxidative Stress, Genotoxicity and Nuclear Alterations. [PDF]

Vet Med Sci
Combined exposure to bifenthrin–chlorpyrifos and bifenthrin–endosulfan mixtures induced oxidative stress, genotoxicity and nuclear abnormalities in Catla catla and Labeo rohita. Antioxidant and DNA damage biomarkers provide sensitive tools for assessing pesticide‐related ecological risks in aquatic environments. ABSTRACT Background The extensive use of

The Micronucleus Test for Occupational Safety. [PDF]

Med Lav
Although less commonly used than internal dose indicators, biological effect indicators can be valuable for Risk Assessment. Among the numerous biomarkers used to date, those that indicate DNA damage could be especially useful for occupational safety, as they predict the risk of carcinogenesis.

Heritability of chromosomal radiosensitivity in breast cancer patients: A pilot study with the lymphocyte micronucleus assay

, 2000
Of breast cancer patients, 30% are sensitive in a lymphocyte assay of radiation-induced chromosome damage (micronucleus induction) compared with 10% of healthy controls.

New direct contact approach to evaluate soil genotoxicity using the Vicia faba micronucleus test. [PDF]

, 2009
A method to assess micronucleus (MN) induction in Vicia faba roots by direct contact exposure to a solid matrix was developed. The procedure comprised a 5-d germination period, as in the well-known method using aqueous extracts.

Assessment of the genotoxicity of Cu and Zn in raw and anaerobically digested slurry with the Vicia faba micronucleus test [PDF]

, 2009
Genotoxicity of Cu and Zn was assessed by use of the micronucleus (MN) test on Vicia faba roots. Plants were exposed to various leachates of rawand anaerobically digested pig slurry, with maximum total concentrations of 200MCu and 600MZn.

Assessment of the genotoxicity of olive mill waste water (OMWW) with the Vicia faba micronucleus test [PDF]

, 2007
The present study concerns the genotoxicity of olive mill waste water (OMWW) generated in mills producing olive oil in Morocco. The Vicia faba micronucleus test was used to evaluate the genotoxicity of OMWW and the six major phenolic compounds identified
