The aim of the study was to investigate the novel endoscopic findings in nasopharyngeal carcinoma (NPC) under narrow-band imaging (NBI) and to determine the reliability of screening NPC by NBI. A total of 79 adults underwent nasopharyngeal biopsy. We proposed five distinctly different findings that need to be examined by NBI: Type I: brownish spots, Type(More)
PURPOSE Tumor eradication by chemoradiotherapy for pharyngeal cancer has not been particularly successful. Targeting epithelial growth factor receptor (EGFR) could be a potential treatment strategy providing additional benefits, but only a subset of these tumors gives a clinically significant response to EGFR inhibitors. The aim has been to identify the(More)
OBJECTIVES To determine the value of narrowband imaging (NBI) screening for the early detection of head and neck squamous cell carcinoma (HNSCC) in patients who have received treatment and to assess the impact of radiotherapy on detection rates. DESIGN Cross-sectional study. SETTING Tertiary referral center. PATIENTS From July 1, 2007, through(More)
Dysfunctional gap junctions caused by GJB2 (CX26) and GJB6 (CX30) mutations are implicated in nearly half of nonsyndromic hearing loss cases. A recent study identified a heterozygous mutation, c.119C>T (p.A40V), in the GJB6 gene of patients with nonsyndromic hearing loss. However, the functional role of the mutation in hearing loss remains unclear. In this(More)
BACKGROUND The purpose of this study was to show the investigated prevalence rate of brownish spots of early cancer under narrow band imaging (NBI) in different sites/types of the epithelium. METHODS In all, 125 adults with early mucosal cancer underwent NBI examination. Four types of epithelium were categorized: keratinized thick stratified squamous(More)
—This study develops a high-performance stand-alone photovoltaic (PV) generation system. To make the PV generation system more flexible and expandable, the backstage power circuit is composed of a high step-up converter and a pulsewidth-modulation (PWM) inverter. In the dc–dc power conversion, the high step-up converter is introduced to improve the(More)
Flavonoids have been demonstrated to exert health benefits in humans. We investigated whether the flavonoid baicalein would inhibit the adhesion, migration, invasion, and growth of human hepatoma cell lines, and we also investigated its mechanism of action. The separate effects of baicalein and baicalin on the viability of HA22T/VGH and SK-Hep1 cells were(More)
The aim of the present study was to explore specific molecular markers that could lead to new insights into the identification of innovative treatments in oral cancer. The role of TGF-β1 (transforming growth factor-β1) and its predictive power in the prognosis of oral cancer has been identified. Human oral cancer cell lines, including SCC4 and SCC25, were(More)
Epstein-Barr virus (EBV) expresses an immediate-early protein, Rta, to activate the transcription of EBV lytic genes and the lytic cycle. This work identifies Ubc9 and PIAS1 as binding partners of Rta in a yeast two-hybrid screen. These bindings are verified by glutathione S-transferase pull-down assay, coimmunoprecipitation, and confocal microscopy. The(More)
Epstein-Barr virus (EBV) expresses the immediate-early protein Rta to activate the transcription of EBV lytic genes and the lytic cycle. We show that RanBPM acts as a binding partner of Rta in yeast two-hybrid analysis. The binding was confirmed by glutathione-S-transferase pull-down assay. A coimmunoprecipitation experiment and confocal microscopy revealed(More)
