To make suggestions regarding how health authorities can reduce the number of students taking up the habit. MATERIALS AND METHODS A cross-sectional survey(More)
PURPOSE To explore the betel nut chewing prevalence among students, analyze the probability and the odds ratio of ex-chewers and current chewers, as well as the correlation between parental behavior characteristics and those of adolescents chewing betel nut. METHODS A cross-sectional survey was designed and 10,288 Taiwanese students answered the(More)

E-learning has altered, and will continue to affect teaching and learning contexts in tertiary education but very little research has been undertaken on university instructor perspectives of technology use in e-learning teaching. This paper explores the perceived benefits of technology use in elearning by university instructors in Taiwan. These perceived(More)
UNLABELLED Focally increased (18)F-FDG uptake in the lateral pharyngeal recess (LPR) of the nasopharynx due to a benign or malignant lesion is not an uncommon finding on PET images. The aim of this study was to evaluate whether, on PET/CT images, (18)F-FDG uptake occurs with characteristic patterns and intensities in various regions of Waldeyer's ring that(More)
RATIONALE AND OBJECTIVES Thymic hyperplasia is associated with hyperthyroidism. Increased thymus 2-[fluorine-18]fluoro-2-deoxy-D-glucose (FDG) uptake in hyperthyroidism patients has been reported. The aim of this study was to analyze the FDG positron emission tomography (PET) thymus uptake spectrum in patients with active hyperthyroidism with correlation(More)
Nitric oxide (NO) deficiency contributes to hypertension. We previously showed that neuronal nitric oxide synthase (nNOS) was involved in hypertension and kidney damage in spontaneously hypertensive rats (SHRs). The protein inhibitor of nNOS (PIN) has been reported to inhibit activity of nNOS.Thus, we tested whether increased PIN in the kidney results in(More)
Blended courses that include both face-to-face and e-learning have been offered in many universities in Taiwan but very little research has been undertaken on instructor perspectives of the challenges they faced in their e-learning teaching. This paper explores the challenges faced by university instructors in a national research-based university in Taiwan.(More)

PURPOSE Lymphoid hyperplasia is not uncommon in the midline roof of the nasopharynx. Most nasopharyngeal carcinoma patients present with primary tumors in the midline of the nasopharynx. The aim of this study was to evaluate the efficacy of 2-[fluorine-18] fluoro-2-deoxy-D-glucose ((18)F-FDG) PET/computed tomography (CT) to differentiate between benign and(More)
