(2010)The inhibitory effects of a standarized apple peel polyphenol-rich extract (APPE) against Helicobacter pylori infection and vacuolating bacterial toxin (VacA) induced vacuolation were investigated. Apple peel polyphenols ...
-
(2009)In the present work, the in vitro effect of a standardized extract of apple peel APPE (60% of total polyphenols; 58% of flavonoids; 30% of flavan-3-ols and procyanidins) was evaluated with regard to the viability of ...
-
(1996)Objectives: We studied prospectively in a single-blind controlled manner the efficacy of 4-wk triple-antibiotic therapy, with amoxicillin (500 mg p.o., t.i.d.), metronidazole (250 mg p.o., t.i.d.), and bismuth subsalicylate ...
