Previously, artesunate (AS) and dihydroartemisinine 7 (DHA7) were found to have antibacterial enhancement activity against Escherichia coli via inhibition of the efflux pump AcrB. However, they were only effective against E. coli standard strains. This study aimed to develop effective antibacterial enhancers based on the previous work. Our results demonstrate that 86 new antibacterial enhancers...

OBJECTIVES Recurrent caries was partly ascribed to lack of antibacterial properties in composite resin. Silver and zinc nanoparticles are considered to be broad-spectrum antibacterial agents. The aim of the present study was to evaluate the antibacterial properties of composite resins containing 1% silver and zinc-oxide nanoparticles on Streptococcus mutans and Lactobacillus. MATERIALS AND ME...

We developed a novel thermal spraying technology for a silver-containing hydroxyapatite (Ag-HA) coating with antibacterial activity to reduce the incidence of implant-associated infections. In this study, we determined the concentration of Ag ions that show antibacterial activity in fetal bovine serum (FBS) and antibacterial activity of the Ag-HA coating in FBS. The minimum inhibitory concentra...
