(2001). Qualitative reasoning techniques to support learning by teaching: The teachable agents project. Abstract This paper describes the use of qualitative reasoning mechanisms in designing computer-based teachable agents that users explicitly teach to solve problems using concept maps. Users can construct the required problem-solving knowledge structures(More)
Hepatitis E virus (HEV) causes acute hepatitis in humans, predominantly by contamination of food and water, and is characterized by jaundice and flu-like aches and pains. To date, no vaccines are commercially available to prevent the disease caused by HEV. Previously, we showed that a monoclonal antibody, 8C11, specifically recognizes a neutralizing(More)
In the field of engineering technology components, electromagnets are widely used. its performance tests are as hot spots, force characteristics effect the whole electromagnetic actuators, it is very necessary to do research on this. The paper finish it with a test stand, on the one hand, the test stand can measure relationship between displacement and(More)
RNA interference (RNAi) has exhibited huge potentials on anti-HIV-1 therapy research. The obtainment of RNAi element targeting to HIV-1 highly effectively and specifically was crucial for relevant research. Recent reports had described that microRNAs (miRNAs) posses more characteristics of inhibition and expression mechanisms than small interfering RNAs(More)
Genes encoding uridine phosphorylase (UP) and thymidine phosphorylase (TP) from Escherichia coli K12 were cloned and recombined respectively into plasmids pET-21a(+) and pET-28a(+). The recombinant plasmids BL21/pET21a-UP and BL21/pET28a-TP were co-transformed into E. coli BL21(DE3) to construct highly effective BTU strain (BL21/pET28a-TP, pET21a-UP)(More)
OBJECTIVE To explore the outcomes of individualized neurosurgical treatments of spastic cerebral palsy. METHODS A total of 452 spastic cerebral palsy patients undergoing microneurosurgery during March 2006 and December 2011 were retrospectively analyzed. Performed on the basis of clinical manifestations, comprehensive procedures included selective cutting(More)
Neuropathic pain is a major health issue that represents considerable social and economic burden worldwidely. In this study, we investigated the potential of catalpol, an iridoid glucoside of Rehmannia glutinosa Steud, to alleviate neuropathic pain. The potential analgesic effects of catalpol were evaluated by chronic constriction injury (CCI) and lumbar 5(More)
BACKGROUND We aimed to evaluate postoperative recovery and short-term outcomes of patients undergoing partial hepatectomy managed with a nonstrict and individual enhanced recovery after surgery (ERAS) program. METHODS A retrospective analysis of 168 partial hepatectomy patients in our institution was included. The discharged day and the respective impact(More)
We developed a high-sensitivity C-reactive protein quantifiable chemiluminescent immunoassay (hs-CRP CLIA). The high-purity native CRP was purified from hepatic cirrhosis patient ascetic fluid by affinity and ion exchange chromatography and used as an immunogen to develop the monoclonal antibodies (mAbs) against CRP. Twenty-two mAbs were identified reactive(More)
