Assessment of hazards and risks associated with dietary exposure to mineral oil for the Belgian population

Source: Food and Chemical Toxicology, Volume 149 (2021) Keywords: CALUX® bioassay endocrine activity genotoxicity Mineral oil aromatic hydrocarbons Mineral oil saturated hydrocarbons Modified Ames test ...

Chemical and toxciological characterization of e-liquid cigarettes

information on their genotoxicity was present. For four of these flavourings, a commercial standard was available and thus could be tested in vitro using an Ames- and micronucleus test. One of the four ...

In Vitro and In Vivo Toxicity Studies on Cymbopogon giganteus Chiov. Leaves Essential Oil from Benin

Mutagenic potential was assessed by the Ames test using Salmonella typhimurium strains TA98 and TA100. Oral acute toxicity was carried out by administration of a single dose of 2000 mg/kg b.w. to Wistar rats ...

In vitro toxicity, genotoxicity and antigenotoxicity of Nigella sativa extracts from different geographic locations

include alkaloids, flavonoids, and terpenoids. Therefore their properties and biological effects may be different. We used the neutral red uptake test, the bacterial Vitotox and Ames assays and the ...

Genotoxic evaluation of the liquids present in electronic cigarettes

animal-free approaches. In addition, the applicability of the Ames test and the in vitro micronucleus test to evaluate the genotoxic potential of e-liquids mixtures was investigated. [Methods]  The study was ...

Antimutagenicity, antioxidant activity and cytotoxicity of n-tetracosanol, eiocosanoic acid and arjunolic acid isolated from Combretum microphyllum (Combretaceae)

isolated. The threecompounds were evaluated for their antimutagenic activity in the Ames test usingSalmonella typhimurium TA98, TA100 and TA102. Furthermore, the isolatedcompounds were assessed for their ...

Publication Type: Dissertation Authors: Ti Thu Ha Nguyen Source: UA, Antwerp, Belgium, p.NA (2017) Accession Number: NA Keywords: Ames assay antigenotoxicity Comet Assay genotoxicity Micronucleus ...

(Q)SAR tools for priority setting: A case study with printed paper and board food contact material substances.

allowed to identify 53 substances for which Ames mutagenicity prediction already has in vitro Ames test results. For further prioritization, additional support could be obtained by applying local i.e. ...

Isolation and characterization of the compounds responsible for the antimutagenic activity of Combretum microphyllum (Combretaceae) leaf extracts

Ames test using Salmonella typhimurium TA98, TA100 and TA102. The antioxidant activity of the three compounds were determined by the quantitative 2,2-diphenyl-1-picrylhydrazyl (DPPH)-free radical ...
