Ames test

My graduation paper focuses specifically on the investigation of method used by the teachers at AMES center and give some suggestions for applying the new methods to enhance the students' self - learning for improvements in their listening skills. The specific aims of the research are as follows: To investigate the teachers' and students' attitudes towards the application of listening methods in self-learning. To find out the most common technique contents exploited by the teachers at AMES center. To examine the students’ preferences for the model practice.

In this paper, the authors continue systematically presenting and supplementing the results obtained after the study, namely the finalization and renaming of the AMES method into the Advanced 2D Multi-electrode Electrical Exploration (AMEE) method, including MC array, data collecting and processing, and testing on theoretical model and practical application to confirm the superiority of this method.

The aim of this study was to evaluate the antimutagenic activity of the methanol extract of Origanum vulgare L. subsp. vulgare. Antimutagenic activity was estimated by employing the plate incorporation AMES/Salmonella histidine reversion assay.

The protective effects of α-keto acids on the mutagenicity of H2O2 and NaN3 was investigated in Salmonella typhimurium TA 98, TA 100, TA 102. H2O2 (340 µg/plate) was mutagenic to the strains TA 98 and TA 102 while NaN3 (1.5 µg/plate) was mutagenic only to TA100.

The genotoxic and antigenotoxic effects of Aloe vera leaf extract (AV) were investigated using the chromosome aberrations (CAs) test for the bone marrow cells of rats, sister chromatid exchanges (SCEs) and micronucleus (MN) and CAs tests for human lymphocytes, and the Ames Salmonella/microsome test system.

The aim of this study was to evaluate the genotoxic effect of a bovine bone-derived hydroxyapatite (HA), Boneplus-xs (B-P-XS). The genotoxicity of B-P-XS was investigated by examining the potential of the xenograft (B-P-XS) to induce gene mutation (evaluated using the Ames test), in vitro chromosome aberration (CA), and sister chromatid exchange (SCE) with tests in cultured human peripheral lymphocytes.

Recently, we have shown that phenyl hydroquinone, a hepatic metabolite of the Ames test-negative carcinogen o-phenylphenol, efficiently induced aneuploidy in Saccharomyces cerevisiae. We further found that phenyl hydroquinone arrested the cell cycle at G1 and G2 ⁄M. In this study, we demonstrate that phenyl hydroquinone can arrest the cell cycle at the G2 ⁄M transition as a result of stabilization of Swe1 (a Wee1 homolog), probably leading to inactivation of Cdc28 (a Cdk1⁄Cdc2 homolog).

That being said, when a specific facility is talked about, for clarity, we refer to it as a proper name and, if necessary, include its function (e.g., Ames 12-Foot Pressure Wind Tunnel). As well, the term “test facilities” and “facilities” can be substituted to mean “WT/PT facilities.” Of course, NASA owns and operates other types of test facilities outside of WT/PT facilities, but our conclusions and recommendations do not apply to them. iii .

With the work of South Africa’s Truth and Reconciliation Commission complete, James L Gibson sets out to test one of its key premises, namely, that truth can facilitate reconciliation and help a nation both to deal with its painful past and to move on to a more democratic future. Drawing on one of the largest and most comprehensive surveys of post-apartheid attitudes to date, and employing innovative conceptual and methodological tools, Gibson’s sophisticated and subtle analysis offers both encouraging and disheartening insights into the success of the truth and reconciliation processs.....
