The association between polymorphisms of COX-2 -765G>C and p53 codon 72, and oral squamous cell carcinoma (OSCC) remains unclear. We investigated the associations between COX-2 and p53 polymorphisms, oral precancerous lesions (OPL), and OSCC. Demographic data and substance use (smoking, drinking, and betel quid chewing) data were collected from 297 patients(More)
BACKGROUND It is generally accepted that the development of cancer in the oral mucosa is preceded by an identifiable non-invasive precursor lesion. The aim of this follow-up study was to estimate the rate and the time to transformation in a group of patients from southern Taiwan with potentially malignant oral epithelial lesions. METHODS The follow-up(More)
The hepatopancreas of the adult male blue crab Callinectes sapidus in intermolt was found to contain substantial amounts of calcium, magnesium, and inorganic phosphorus, averaging about 260, 20, and 250 microg-atoms per g wet tissue, respectively, accounting for over 10% of the tissue dry weight. Electron microscopy of the intact tissue showed three(More)
Cytokine production capacity varies among individuals and depends on cytokine gene polymorphisms. Transforming growth factor-beta 1 (TGF-β1) plays a significant role in regulating the proliferation and apoptosis of epithelial cells. Interleukin 10 (IL-10) is an immunoregulatory cytokine with biological functions of anti-inflammation, immunosuppression,(More)
PURPOSE Various types of temporary implants have been introduced to serve as orthodontic anchorage. The hypothesis of this study is that microimplants of 1.2 mm diameter can be used as orthodontic anchors, and that their success is related to their length. The aim of this study is to determine the incidence of anchor retention after orthodontic force(More)
BACKGROUND Many single nucleotide polymorphisms (SNPs) have been found to be associated with oral cancer but the biological interactions through SNPs are seldom addressed. In this study, we focused on the joint effect for SNP combinations of four DNA repair genes, X-ray repair cross-complementing groups (XRCCs) 1-4, involved in major cancer-related(More)
Software-based self-test (SBST) is emerging as a promising technology for enabling at-speed testing of high-speed embedded processors testing in an SoC system. For SBST, test routine development or generation can base on deterministic and random methodology. The deterministic test methodology develops the test program for a pipeline processor using the(More)
