Modelling Semantic Knowledge for a Word Completion Task Jianhua Li Master of Science Graduate Department of Computer Science University of Toronto 2006 To assist people with physical disabilities in text entry, we have studied the contribution of semantic knowledge in the word completion task. We have first constructed a semantic knowledge base (SKB) that(More)
Retinoblastoma (Rb) is a common childhood intraocular cancer that affects approximately 300 children each year in the United States alone. 2-Methoxyestradiol (2ME), an endogenous metabolite of 17-β-estradiol that dose not bind to nuclear estrogen receptor, exhibits potent apoptotic activity against rapidly growing tumor cells. Here, we report that 2ME(More)
Endothelial cell (EC) survival is critical in the maintenance of endothelial function as well as in the regulation of angiogenesis and vessel integrity since endothelial dysfunction is the initial lesion of atherosclerosis. The goal of this study was to examine the effect of diazoxide, a mitochondrial ATP-sensitive K+(mito KATP) channel opener, on aorta ECs(More)
Our objective was to characterize the elasticity of hydrogel formulations intended to mimic physical properties that cells and tissues experience in vivo. Using atomic force microscopy (AFM), we tested a variety of concentrations in a variety of biomaterials, including agarose, alginate, the collagens, fibrin, hyaluronic acid, kerateine, laminin, Matrigel,(More)
We report the fabrication of the La2/3Sr1/3MnO3 (LSMO)/graphene/Co sandwich structures employing single-layer graphene as the interlayer. Appreciable negative spin valve signals were observed from room temperature to 5 K. We find that the devices demonstrate nonlinear current-voltage (I-V) characteristics around room temperature, indicating that the(More)
The complete chloroplast (cp) sequence of the salt cress (Eutrema salsugineum), a plant well-adapted to salt stress, was presented in this study. The circular molecule is 153,407 bp in length and exhibit a typical quadripartite structure containing an 83,894 bp large single copy (LSC) region, a 17,607 bp small single copy (SSC) region, and the two 25,953 bp(More)
As the second most prevalent hematologic malignancy, multiple myeloma (MM) remains incurable and relapses due to intrinsic or acquired drug resistance. Therefore, new therapeutic strategies that target molecular mechanisms responsible for drug resistance are attractive. Interactions of tumor cells with their surrounding microenvironment impact tumor(More)
We developed a novel substrate made from fugitive glue (styrenic block copolymer) that can be used to analyze the effects of large strains on biological samples. The substrate has the following attributes: (1) It is easy to make from inexpensive components; (2) It is transparent and can be used in optical microscopy; (3) It is extremely stretchable as it(More)
Sinalliaria is a new small genus of Brassicaceae with only two species (S. grandifolia and S. limprichtiana) endemic in eastern China. Because of their limited distribution, identifying the species and sources of S. grandifolia and S. limprichtiana are important for biodiversity conservation and ecological preservation. The chloroplast genome sizes of(More)
In this study, we determined the complete chloroplast genomes from two crucifer species of the Eutrema genus. The sizes of the two cp genomes were 153 948 bp (E. yunnanense) and 153 876 bp (E. heterophyllum). Both genomes have the typical quadripartite structure consisting of a large single copy region, a small single copy region and two inverted repeats.(More)
