Influence of luting material filler content on post cementation.

29 Sep 2009 Luting of fiber posts to intra-radicular dentin represents the worst-case scenario in terms of control of polymerization shrinkage. This study tested the hypothesis that filler content of resin cements does not influence luting of fiber posts to ... Read more...

PEGylation strategies for active targeting of PLA/PLGA nanoparticles.

29 Sep 2009 This work evaluates various techniques for the incorporation of poly(ethylene glycol) (PEG) onto biodegradable nanoparticles (NPs) of poly(lactic-co-glycolic acid) (PLGA) or poly(lactic acid) (PLA) with the purpose of providing a functional site for ... Read more...

Smooth muscle cell adhesion in surface-modified three-dimensional copolymer scaffolds prepared from co-continuous blends.

29 Sep 2009 In this article, tissue-engineering scaffolds were fabricated from P(epsilon-CL-co-D,L-LA)-PEG-P(epsilon-CL-co-D,L-LA) copolymers using co-continuous blends with polystyrene as the porogen phase. By means of static annealing and following extraction ... Read more...
