OBJECTIVE To investigate the effect of curcumin on indoleamine 2, 3 -dioxygenase (IDO) expression induced by IFN-gamma in cancer cells. METHODS A431, HeLa, HepG2, CNE2 cells were treated with curcumin for 24 hours, then the cell proliferation was detected by methyl thiazolyl tetrazolium (MTF) assay. The effects of curcumin on IDO expression induced by(More)
OBJECTIVE To analyze the chemical constituents of the non-alkaloid fraction of Uncaria macrophylla. METHODS The constituents were separated and purified by silica gel chromatography and recrystalization, and their structures were identified by infrared, mass and nuclear magnetic resonance spectrometry. RESULTS Six compounds were isolated from the(More)
In this study, we designed a data broadcasting method called a windmill indexing algorithm (WIA) This WIA pro­ vides new scheduling technology for broadcast systems and a new information searching method for mobile devices that simultaneously conserves mobile device energy and maintains favorable access latency of broadcast messages. The WIA con­ structs(More)
