Antimicrobial cationic surfactant-loaded hydrogel coatings in preventing medical device-associated infections

British Journal of Pharmacy, 2022
Hydrogels described herein were developed as anti-microbial coating materials. Three different hydrogels, p(HEMA), p(85%HEMA-co-15% MMA), and p(85% HEMA-co-15% MAA) were loaded with two cationic surfactants, BAK, and DDAB, respectively.

Effect of 2-hydroxyethyl methacrylate on antioxidant responsive element-mediated transcription: a possible indication of its cytotoxicity. [PDF]

PLoS ONE, 2013
The resin monomer 2-hydroxyethyl methacrylate (HEMA) is known to be more cytotoxic than methyl methacrylate (MMA). Using a luciferase reporter assay system, we previously showed that MMA activates the glutathione S-transferase alpha 1 gene (Gsta1 ...
