Using the comet and micronucleus assays for genotoxicity studies: a review
Physical, chemical and biological agents can act in the DNA, resulting in mutation involved in cancer. Thus, genotoxic tests are required by regulatory agencies in order to evaluate potential risk of cancer. Among these ...
Genotoxicity assessment of water soluble fractions of biodiesel and its diesel blends using the Salmonella assay and the in vitro MicroFlow (R) kit (Litron) assay
(Pergamon-Elsevier B.V. Ltd, 2012-02-01)
The designation of biodiesel as an environmental-friendly alternative to diesel oil has improved its commercialization and use. However, most biodiesel environmental safety studies refer to air pollution and so far there ...
Development of pipette tip gap closure migration assay (s-ARU method) for studying semi-adherent cell lines
This work presents a pipette tip gap closure migration assay prototype tool (semi-adherent relative upsurge—s-ARU—method) to study cell migration or wound healing in semi-adherent cell lines, such as lymph node carcinoma ...

Cytotoxicity, genotoxicity and antimutagenicity of hexane extracts of Agaricus blazei determined in vitro by the comet assay and CHO/HGPRT gene mutation assay
(Elsevier B.V., 2005-06-01)
Agaricus blazei Murrill ss. Heinem, known as the sun mushroom or himematsutake, is a basidiomycete native to Brazil, which is popular for its medicinal properties. The aim of this study was to test hexane extracts (one ...
Genetic biomonitoring of an urban population exposed to mutagenic airborne pollutants
(Pergamon-Elsevier B.V. Ltd, 2009-10-01)
Biomonitoring studies have increased as a consequence of risks and effects to human health on exposure to environmental contaminants, mainly air pollutants. Genetic biomarkers are useful tools for the early assessment of ...
Electrochemical determination of the antioxidant capacity: The ceric reducing/antioxidant capacity (CRAC) assay
The CRAC assay is a direct electron transfer test of antioxidant capacity for several organic compounds. The ability of eight different compounds in reducing Cc 41 was studied by chronoamperometric measurements of the ...
Microbiological Assay for the Determination of Colistin Sulphate
(Bentham Science Publ Ltd, 2014-01-01)
An innovative microbiological assay was developed for the determination of colistin sulphate at various concentrations (192-469 IU/mL); using Bordetella bronchiseptica ATCC 4617 as microorganism test. This assay revealed ...
