The sensitivity of hepatoma cells to total aqueous extract(TAE) from Artemisia argyi was investigated. HepG2 cells were treated with the extract at the concentrations of 17.5 mg(Artemisia argyi)/ml, 35 mg(Artemisia argyi)/ml, and 70mg(Artemisia argyi)/ml. Inverted microscope observation found that the total aqueous extract induced cell shrinkage after 12h, and ultimately cell death after persistent...
Web sequential pattern mining is an important way to learn the access behavior of Web users. In this paper, we present an efficient method of Web sequential pattern mining in the e-learning environment. Different from traditional mining methods, we categorize the user sessions into human user sessions, crawler sessions and resource-download user sessions. Then we filter out the non-human user sessions,...
Objectives: To compare anti-tumor activities of different extracts from the medicinal plants Pinellia ternata and its allied species.Methods: MTT cell proliferation assay was used to evaluate the cytotoxicity of the extracts on Bel-7402, HT-29, Hela cells. FCM assay and DNA fragmentation analysis were used to detect cell apoptosis. Immunohistochemical SABC method was performed for detection of the...
