introduction: the a im of this study is the evaluation of the effect of antimicrobial photodynamic therapy with radachlorin on staphylococcus aureus and escherichia coli. new windows are open in the antimicrobial field so-call photodynamic therapy that incorporates a nonpoisonous photosensitizer (ps) with innocuous special wavelength photons to excite the ps. methods: two strains of bacteria us...

conclusions caffeic acid treatment reduced bacterial growth and resulted in a decreased number of colony formation. the simultaneous effect of caffeic acid and laser at three time courses showed a synergic effect in reducing colony formation compared to the control and caffeic acid, and laser alone. objectives the aim of this study was to investigate the effect of caffeic acid and low-power las...

plant extracts are rich sources of natural antioxidant and antibacterial compounds. in recent decades, the need for using natural antioxidants in foods, pharmaceuticals and cosmetics has promopted extensive scientific research. the purpose of this study was to investigation of effect of different percentages of rosemary extract (0, 1, 2.5 and 5%) on the quality, chemical and microbial of the pr...

conclusions anova results showed that the effect of cycle and time on the selected bacterial removal efficiency were more important than that of the microbial concentration. results the results showed that e. coli and e. faecalis were effectively treated at 10 pulse/s in 9 minutes and 6 log cfu/ml bacterial suspension (p < 0.0001 for e. coli with 99.99% (4 log) and p = 0.0002 for e. faecalis wi...
