When two terms occur together in a document, the probability of a close relationship between them and the document itself is greater if they are in nearby positions. However , ranking functions including term proximity (TP) require larger indexes than traditional document-level indexing , which slows down query processing. Previous studies also show that(More)
Current Intrusion Detection Systems (IDS) examine all data features to detect intrusion or misuse patterns. Some of the features may be redundant or contribute little (if anything) to the detection process. The purpose of this study is to identify important input features in building an IDS that is computationally efficient and effective. This paper(More)
Gene expression is suppressed by DNA methylation. The goal of this study was to identify genes whose CpG site methylation and mRNA expression are associated with recurrence after surgical resection for hepatocellular carcinoma (HCC). Sixty-two HCCs were examined by both whole genome DNA methylation and transcriptome analysis. The Cox model was used to(More)
BACKGROUND AND AIMS Brivanib is a selective inhibitor of vascular endothelial growth factor receptor (VEGFR) and fibroblast growth factor receptor (FGFR) tyrosine kinases, which are both involved in mechanisms of liver fibrosis. We hypothesized that inhibition of VEGFR and FGFR by brivanib would inhibit liver fibrosis. We therefore examined the effect of(More)
The telomerase reverse transcriptase (TERT) is primarily known for its ability to elongate telomeres for maintaining chromosomal integrity and delaying cellular senescence. It plays an important role in cell proliferation, differentiation, tumorigenesis, and aging. Telomerase includes two core components—an internal RNA moiety acting as a template of DNA(More)
A trichomonad-like parasite isolated from canine fecal samples in Changchun, China was successfully cultivated in vitro using RPMI1640 medium supplemented with 10 % heat-inactivated calf serum and antibiotics. These were then subjected to scanning and transmission electron microscopy for ultrastructural study. This parasite has four anterior flagella of(More)
Coccidiosis is one of the most important protozoan diseases and inflicts severe economic losses on the poultry industry. The aim of this study was to evaluate the capacity of Bacillus Calmette–Guerin (BCG) to deliver apical membrane antigen1 (AMA1) of Eimeria maxima to stimulate specific cellular and humoral immune responses in chickens. Day-old birds were(More)
BACKGROUND/AIMS Screening for hepatitis B virus (HBV) is recommended in populations with anticipated prevalence ≥2%. This study surveyed HBV screening and vaccination practices of Asian American primary care providers (PCPs). METHODS Approximately 15,000 PCPs with Asian surnames in the New York, Los Angeles, San Francisco, Houston, and Chicago areas were(More)
BACKGROUND/AIMS The BARD score is a model to detect advanced liver fibrosis in nonalcoholic fatty liver disease (NAFLD) patients. The aims of this study were to identify additional factors and then to build an enhanced version of the BARD score. METHODS One hundred seven patients with biopsy-proven NAFLD were enrolled retrospectively. Logistic regressions(More)
