Nonparametric regression analysis of data from the Ames mutagenicity assay.
The Ames assay has received widespread attention from statisticians because of its popularity and importance to risk assessment. However, investigators have yet to routinely apply modern regression methods that have been available for more than a decade. We study yet another approach, the application of nonparametric regression techniques, not as the ultimate solution but rather as a framework ...
متن کاملThe Ames Salmonella/microsome mutagenicity assay.
The Ames Salmonella/microsome mutagenicity assay (Salmonella test; Ames test) is a short-term bacterial reverse mutation assay specifically designed to detect a wide range of chemical substances that can produce genetic damage that leads to gene mutations. The test employs several histidine dependent Salmonella strains each carrying different mutations in various genes in the histidine operon. ...
متن کاملAmes II Mutagenicity Assay Technical Documentation
Statistical features of a base-specific Salmonella mutagenicity assay are considered in detail, following up on a previous Ž . report comparing responses of base-specific Salmonella Ames IIe strains with those of traditional tester strains. In addition to using different Salmonella strains, the new procedure also differs in that it is performed as a microwell fluctuation test, as opposed to the...
متن کاملStuctural Analysis of Molecular Networks: AMES Mutagenicity
The characterization of chemical compounds based on their molecular graphs is an important task for identifying properties such as toxicity or mutagenicity. We used different groups of topological descriptors using the AMES mutagenicity data. Instead of optimizing the classification performance, the aim of this study is to perform a structural analysis of the underlying set of molecular graphs ...
