Green tea polyphenol (GTP) is one of the most promising chemopreventive agent for cancer; it can inhibit cancer cell proliferation and induce apoptosis through p53-dependent cell signaling pathways. Unfortunately, many tumor cells lack the functional p53, and little is known about the effect of GTP on the p53-deficient/mutant cancer cells. To understand the(More)
The aim of the present study was to determine the effects of 12-O-tetradecanoylphorbol-13-acetate (TPA) and diethyldithiocarbamate (DDTC) alone or in combination on human pancreatic cancer cells cultured in vitro and grown as xenograft tumors in nude mice. Pancreatic cancer cells were treated with either DDTC or TPA alone, or in combination and the number(More)
According to the characteristics of OCT images for macula edema, we studied a method for segmentation of the macula edema. Based on the Chan-Vese model, we proposed an improved level-set algorithm. With defining the integer-valued signed function directly, the curve could evolute outward or inward by changing the inside neighboring rid points and outside(More)
