Title: Ceinwen A Schreiner: Innovator in Mutagenicity Evaluation
Introduction
Ceinwen A Schreiner is a notable inventor based in Meadowbrook, PA (US). She has made significant contributions to the field of mutagenicity evaluation, holding a total of 4 patents. Her work primarily focuses on methods for assessing the carcinogenic potential of hydrocarbon mixtures, particularly those derived from petroleum.
Latest Patents
One of her latest patents is a method for evaluating mutagenicity. This innovative approach allows for the rapid and reliable determination of the potential carcinogenic activity of hydrocarbon mixtures. The process involves nitrating a sample of the mixture under specific conditions to convert polynuclear aromatic hydrocarbons into their nitrated derivatives. The product is then incubated with an inoculum of Salmonella typhimurium tester strain T98. The excessive production of revertant colonies serves as a measure of the mutagenic activity of the oil, which correlates with dermal carcinogenic activity. Another significant patent involves a very rapid and sensitive method for determining the potential mutagenicity and/or carcinogenicity of certain petroleum oils. This method utilizes nitration of the oil and compares the light absorbance of its nitrated material with that of oils known for their mutagenicity and/or carcinogenicity.
