Diesel Emissions and the Ames Test: A Commentary

Journal of the Air Pollution Control Association, 1980
Participates emitted from diesel engines contain substances which produce mutations in the bacterial assay known as the Ames Salmonella/microsome test. The limitations and value of the Ames test data are discussed here.

The test that changed the world: The Ames test and the regulation of chemicals

Mutation Research/Genetic Toxicology and Environmental Mutagenesis, 2019
The bacterial strains and mutagenicity test procedure developed by Bruce Ames, and published in 1973, greatly enhanced the ability of laboratories to test chemicals for mutagenicity. The test that became known as the "Ames Test" was simple to perform, took only two days, was relatively inexpensive, and was easily transferrable to other laboratories ...

Testing the atomic structure of beryllium with AMS

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2002
Abstract If the Pauli exclusion principle were violated, the electronic structure of Be could be 1s 4 (denoted by Be ′ ) rather than 1s 2 2s 2 . This paper describes the results of an experimental search for Be ′ , carried out at PRIME Lab, the Purdue Rare Isotope Measurement Laboratory. In the process of setting stringent constraints on Be ′ using

Ames Test of Ferrate Treated Water

Journal of Environmental Engineering, 1983
The Ames test is used to detect the presence of mutagenic/carcinogenic by‐products in ferrate treated water samples that had been spiked with selected priority pollutants. The gas chromatograph analysis is used to measure the efficiency of removing the substance to be removed but could not be used to detect the production of such by‐products.

Der Ames-Test als Biomarker

HNO, 2001
Hintergrund und Fragestellung. Die Inzidenz maligner Tumoren des Kopf-Hals-Bereichs steigt weltweit an. Hauptrisikofaktoren sind der chronische Tabak- und Alkoholabusus. Durch die Erkennung von Hochrisikopatienten konnen fruhzeitig diagnostizierte Tumoren mit guten Heilungsaussichten behandelt werden.

Automated modification of the Ames test with COBAS Bact

Mutation Research Letters, 1985
The automatic analyser for microbiology "COBAS Bact" from Roche, supplemented by a Hewlett-Packard 9816S is used to automate the Salmonella mutagenicity test, developed by Ames. More than 30 compounds were tested in this system and the results were shown to be in good agreement with those obtained with the standard Ames test.

Mutagenicity of β-glucuronidase in the Ames test

Mutation Research Letters, 1985
Summary The enzyme preparation β-glucuronidase/arylsulphatase from Helix pomatia (Boehringer) caused base-pair substitutions in Salmonella typhimurium TA100 and TA1535 strains within the dose range of 0.50–50 μd per plate. No effect was observed in the TA98 strain.
