In Vitro Mutagenic and Genotoxic Assessment of a Mixture of the Cyanotoxins Microcystin-LR and Cylindrospermopsin [PDF]

, 2019
The co-occurrence of various cyanobacterial toxins can potentially induce toxic effects different than those observed for single cyanotoxins, as interaction phenomena cannot be discarded. Moreover, mixtures are a more probable exposure scenario. However,

Assessment of methyl methacrylate genotoxicity by the micronucleus test

Brazilian Oral Research, 2013
The aim of this study was to evaluate the genotoxic potential of methyl methacrylate (MMA) vapor by simulating standard occupational exposure of 8 hours per day and using the micronucleus test. We used 32 adult male Wistar rats divided into three groups:

The effect of HIV and antiretroviral therapy on chromosomal radiosensitivity [PDF]

, 2015
Introduction: Antiretroviral Treatment (ART) has led to an improvement in survival of HIV infected individuals. Some of them will develop cancer during the course of their infection and will require radiation therapy.

Evaluation of the repeated-dose liver and gastrointestinal tract micronucleus assays with 22 chemicals using young adult rats: summary of the collaborative study by the Collaborative Study Group for the Micronucleus Test (CSGMT)/The Japanese Environmental Mutagen Society (JEMS) - Mammalian Mutagenic

Mutation Research. Genetic Toxicology and Environmental Mutagenesis, 2015
The repeated-dose liver micronucleus (RDLMN) assay using young adult rats has the potential to detect hepatocarcinogens. We conducted a collaborative study to assess the performance of this assay and to evaluate the possibility of integrating it into ...

Biocompatible polymer-assisted dispersion of multi walled carbon nanotubes in water, application to the investigation of their ecotoxicity using Xenopus laevis amphibian larvae [PDF]

, 2013
Carbon nanotubes (CNTs) tend to readily agglomerate and settle down in water, while the adsorption of compounds present in natural aquatic media could enhance their dispersion and stabilization in the water column.

Is there a causal association between genotoxicity and the imposex effect? [PDF]

, 2006
There is a growing body of evidence that indicates common environmental pollutants are capable of disrupting reproductive and developmental processes by interfering with the actions of endogenous hormones.

A Double Fluorescent Staining Method Increases the Sensitivity of the Cytokinesis-Block Micronucleus Assay

Methods and Protocols
The micronucleus test is one of the most popular genotoxicity assays. In order to avoid underestimation of micronuclei frequencies by counting non-replicating cells, the cytokinesis-blocked micronucleus test has been developed.

MICRONUCLEUS TEST OF MOFEZOLAC (N-22)

The Journal of Toxicological Sciences, 1990
A micronucleus test using BDF1 male mice was conducted in order to evaluate the in vivo mutagenicity of mofezolac (N-22). N-22 was orally administered at doses of 75, 150, 300 and 600 mg/kg, with a sampling time of 24 hr. The frequency of polychromatic erythrocytes with micronuclei was 0.07-0.08% in the groups treated with N-22 and did not differ ...
