Proteomic analysis of Staphylococcus aureus biofilms grown in vitro on mechanical heart valve leaflets.
The in vitro colonization of three commercial heart valve leaflets by Staphylococcus aureus was investigated. The leaflets, made of pyrolytic carbon alloyed with or without silicon, displayed similar surface properties (wettability, roughness) and were readily colonized by S. aureus […]

Supramolecular hydrogels based on self-assembly between PEO-PPO-PEO triblock copolymers and alpha-cyclodextrin.
This article reports a detailed study on the hydrogel formation of poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) (PEO-PPO-PEO) triblock copolymers with alpha-cyclodextrin (alpha-CD) in aqueous solutions. The gelation kinetics and the gel rheological properties were studied using viscometry. The sol-gel phase transitions were studied […]
