Previous analytical studies of industrial samples of trichloroethylene (TRI) have revealed the presence of mutagenic and carcinogenic epoxides which, it was proposed, might be responsible for the carcinogenicity of such samples, as demonstrated with mice in other laboratories. To test

10 aryl propylene oxides and 6 aryl butylene oxides were synthesized. Dose-mutagenicity relationships were studied for these compounds and for 1,2-epoxybutane, using both the preincubation and plate incorporation Ames tests with Salmonella typhimurium strains TA100 and TA1535. Structure-mutagenicity relationships were

Prevention of Pseudomonas aeruginosa binding to soft-contact lenses (SCLs) may curtail sight-threatening microbial keratitis. Substrate surface wettability is known to modulate adhesion of P. aeruginosa. This study investigates the use of aqueous alkoxylate block co-polymer surfactants for enhanced wettability and
