Anthocyanin-rich extracts, potent antioxidants and commercially available food coloring agents, have been reported to inhibit growth of various cancer cell lines. We investigated the effect of semipurified anthocyanin-rich extract from fruits of Aronia meloncarpa, on normal colon and colon cancer cell lines. A 24-h exposure to 50 mg monomeric anthocyanin/ml(More)
Susceptibilities to fourteen antimicrobial agents important in clinical medicine and agriculture were determined for 752 Escherichia coli isolates of serotypes O26, O103, O111, O128, and O145. Strains of these serotypes may cause urinary tract and enteric infections in humans and have been implicated in infections with Shiga toxin-producing E. coli (STEC).(More)
The aim of this study was to investigate the chemoprotective activity of anthocyanin-rich extracts (AREs) from bilberry (Vaccinium myrtillus), chokeberry (Aronia meloncarpa) and grape (Vitis vinifera) by assessing multiple biomarkers of colon cancer in rats treated with a colon carcinogen, azoxymethane. Male F344 rats (n = 40) were fed AIN-93 diet (control)(More)
