BACKGROUND: The prevalence and clinical relevance of Buried Barrett’s (BB) epithelium after radiofrequency ablation (RFA) in Barrett’s esophagus (BE) is questioned. Recent studies using small optical coherence tomography (OCT) catheters for scanning underneath the neosquamous epithelium demonstrated a high prevalence of tissue structures that might correspond to BB. Histological correlation, ho...

BACKGROUND AND AIMS The prevalence and clinical relevance of buried Barrett's glands (BB) after radiofrequency ablation (RFA) in Barrett's esophagus (BE) are debated. Recent optical coherence tomography studies demonstrated a high prevalence of BBs. Direct histological correlation, however, has been lacking. Volumetric laser endomicroscopy (VLE) is a second-generation optical coherence tomograp...

AIM To determine specific volumetric laser endomicroscopy (VLE) imaging features associated with neoplasia at the gastroesophageal junction (GEJ) and gastric cardia. METHODS During esophagogastroduodenoscopy for patients with known or suspected Barrett's esophagus, VLE was performed before biopsies were taken at endoscopists' discretion. The gastric cardia was examined on VLE scan from the GE...

Communication is one of the main elements in the educational process and the non-verbal communication including eye blink, which is one of the key non-verbal method, owns the highest portion of the communication. The objective of this paper is to evaluate the role of eye blink in the Virtual Learning Environment (VLE). The eye blink is introduced in the VLE and the role of the eye blinking in t...

This thesis presents a Web-based Virtual Learning Environment (VLE) called the Education through Virtual Experience (EVE) Portal which supports eScience learning for schoolchildren. The VLE guides students and teachers in the production of collaborative research papers to summarize their inquirybased activities. This thesis details the formative evaluations carried out on the VLE and provides e...

This study investigates the significance of Rogers’ Diffusion of Innovations (DOI) theory with regard to the use of a Virtual Learning Environment (VLE) at the Royal University of Bhutan (RUB). The focus is on different adoption types and characteristics of users. Rogers’ DOI theory is applied to investigate the influence of five predictors (relative advantage, complexity, compatibility, triala...
