forsythia/albumin

Forsythia suspensa metabolites have many bioactivities, such as selective immuno suppression, antioxidation, anti-hepatic injury, etc. In the present study, the interactions of the three metabolites with BSA have been investigated in a buffer (pH 7.40) using multi-spectroscopic techniques in

Porphyromonas gingivalis is considered the principal etiologic agent and keystone pathogen of chronic periodontitis. As an auxotrophic bacterium, it must acquire heme to survive and multiply at the infection site. P. gingivalis HmuY is the first member of a novel family of hemophore-like proteins.

OBJECTIVE To evaluate the adhesion of selected bacterial strains incl. expression of important virulence factors at dentin and titanium SLA surfaces coated with layers of serum proteins. METHODS Dentin- and moderately rough SLA titanium-discs were coated overnight with human serum, or IgG, or human
