Parthenolide (PN) is the main sesquiterpene lactone found in feverfew with potent anti-inflammatory function. The anticancer property of PN has been demonstrated in both in vitro cell culture and in vivo animal model, while the molecular mechanisms remain to be further elucidated. In the present study, we evaluated the involvement of nuclear transcription(More)
A new three-dimensional (3D) supramolecular framework, [Ag2(bipy)2(bdc)·4H2O]n 1, has been synthesized by the ultrasonic reaction of Ag2O, bipy and H2bdc (H2bdc = 1,4-benzenedicarboxylic acid; bipy = 4,4′-bipyridine) at room temperature. It exhibits a new 3D supramolecular framework which is built from cationic Ag-bipy chains and anionic bdc-H2O sheets(More)
OBJECTIVE To study the effects of sodium selenite on expression of telomerase reverse transcriptase mRNA, c-Myc and p53 induced by cadmium chloride in rat liver. METHODS Male SD rats were divided randomly into 6 groups, each group had 5 animals. The groups comprised the control group, Se group (5 micromol/kg sodium selenite), 5 micromol/kg cadmium(More)
OBJECTIVE To study the effects of selenium on DNA damage, apoptosis and c-myc, c-fos, and c-jun expression in rat hepatocytes. METHODS Sodium selenite at the doses of 5, 10, and 20 micromol/kg was given to rats by i.p. and there were 5 male SD rats in each group. Hepatocellular DNA damage was detected by single cell gel electrophoresis (or comet assay).(More)
In self-managing software teams, developers with complementary skills collaborate with each other to improve productivity and increase innovation. Due to nature of innovation, managers in these teams will acquire only summarized information from developers to avoid micromanagement. They will not plan fine-grained activities but leave responsibility and(More)
