The n-gram inverted index has two major advantages: language-neutral and error-tolerant. Due to these advantages, it has been widely used in information retrieval or in similar sequence matching for DNA and protein databases. Nevertheless, the n-gram inverted index also has drawbacks: the size tends to be very large, and the performance of queries tends to(More)
Synthetic polymer vascular patches used in cardiovascular surgery have shortcomings such as thrombosis, intimal hyperplasia, calcification, infection, and no growth potential. Tissue-engineered vascular patches using autologous vascular cells may solve these problems. In this study, we developed a tissue-engineered vascular patch using autologous bone(More)
Agaricus blazei (H1 strain) was tested for its anticancer activity using a sarcoma 180 (S180) inoculation model and the changing patterns of splenocyte subsets were examined. Its hot-water extract was administered orally to ICR and KSN nude mice that were inoculated with S180. The growth of S180 was significantly inhibited in A.blazei treated groups. Pan T(More)
Recent data stream systems such as TelegraphCQ have employed the well-known property of duality between data and queries. In these systems, query processing methods are classified into two dual categories -- <i>data-initiative</i> and <i>query-initiative</i> -- depending on whether query processing is initiated by selecting a data element or a query.(More)
We propose the notion of tight-coupling [K. Whang et al., (1999)] to add new data types into the DBMS engine. In this paper, we introduce the Odysseus ORDBMS and present its tightly-coupled IR features (US patented). We demonstrate a Web search engine capable of managing 20 million Web pages in a non-parallel configuration using Odysseus.
ÐSpatial join finds pairs of spatial objects having a specific spatial relationship in spatial database systems. Since spatial join is a fairly expensive operation, we need an efficient algorithm taking advantage of the characteristics of available spatial access methods. In this paper, we propose a spatial join algorithm using corner transformation and(More)
Methylsulfonylmethane (MSM) is an organosulfur compound and the health benefits associated with MSM include inflammation. Although MSM has been shown to have various physiological effects, no study has yet focused on inflammasome activation. The inflammasome is a multiprotein complex that serves as a platform for caspase 1-dependent proteolytic maturation(More)
Arsenic trioxide (As(2)O(3)) induces both the differentiation and apoptosis of acute promyelocytic leukemia cells in a concentration dependent manner. We assessed the effects of As(2)O(3) in CADO-ES Ewing's sarcoma (ES), JK-GMS peripheral primitive neuroectodermal tumor (PNET), and SH-SY5Y neuroblastoma cells, as they share common histogenetic backgrounds.(More)
Translational studies have explored the therapeutic effects of stem cells, raising hopes for the treatment of numerous diseases. Here, we evaluated the therapeutic effect of chorionic plate-derived mesenchymal stem cells (CP-MSCs) isolated from human placenta and transplanted into rats with carbon tetrachloride (CCl(4))-injured livers. CP-MSCs were analyzed(More)
Hepatocellular carcinoma (HCC) can cause severe complications, resulting in a high incidence of recurrence after treatment of the primary tumor. Recently, we have shown that nicotinamide effectively inhibits the growth and progression of bladder tumors by up-regulating RUNX3 and p300 expression. Therefore, in this study, the efficacy and inhibitory(More)
