Approximately 50% of Helicobacter pylori strains produce a toxin in vitro that induces vacuolation of eukaryotic cells. To determine whether ion transport pathways are important in the formation of toxin-induced vacuoles, HeLa cells were incubated with H. pylori toxin in the presence of nine different inhibitors of ion-transporting ATPases. Oligomycin, an(More)
Aflatoxin B1 (AFB1) is a fungal toxin that has been associated with primary hepatocellular carcinoma (HCC) in humans. This study was undertaken to determine the cellular and molecular mechanisms by which the antioxidants beta-carotene and lycopene inhibit AFB1-induced toxic changes in human hepatocytes (HepG2 cells). An in vitro system was optimized to test(More)
The therapeutic effects of homoeopathic Arsenicum album potencies were investigated in-vitro, using a continuous cell line (MT4), pre-intoxicated with arsenic trioxide (As(2)O(3)), and then treated with succussed and unsuccussed homoeopathic potencies, 6CH, 30CH and 200CH. This study aimed to verify the homoeopathic law of similars and to determine whether(More)
BACKGROUND Increased intake of probiotic dietary fibre reduces colonic cancer risk. Modified citrus pectin (MCP) requires optimal bioactivity to inhibit galectin-3 (GAL-3) and vascular endothelial growth factor (VEGF). This study evaluated the preventative effect of modified pectin alginate (MCPA) probiotic microbeads on azoxymethane (AOM)-induced colonic(More)
