The toxicity of the quaternary ammonium compound benzalkonium chloride alone and in mixtures with other anionic compounds to bacteria in test systems with Vibrio fischeri and Pseudomonas putida

Ecotoxicology and Environmental Safety, 2008
Mixtures of chemicals are present in the aquatic environment but standard testing methods assess only single compounds. One aspect of this question is the importance of the formation of ionic pairs, for example from quaternary ammonium compounds with organic anions, and the significance of the ionic pairs for bacterial toxicity in the aquatic ...

Epoxy resin‐based sealers modified with clay nanoparticles: Evaluation of their physicochemical and mechanical properties

European Journal of Oral Sciences, Volume 134, Issue 2, April 2026.
Abstract Epoxy resin‐based sealers are commonly used in endodontic treatment due to their superior physicochemical properties. Therefore, it is important to utilize these materials by enhancing their properties. Nonetheless, several of their properties remain suboptimal, including the relatively prolonged setting time, the moderate yet clinically ...

New image analysis of large food particles can discriminate experimentally suppressed mastication [PDF]

, 2012
Objective parameters that could provide a basis for food texture selection for elderly or dysphagic patients have not been established. We, therefore, aimed to develop a precise method of measuring large particles (>2 mm in diameter) in a bolus and an ...
