cDNAs encoding large-conductance Ca2+-activated K+ channel alpha-subunit (rSlo) were obtained from rat brain. From the DNA sequence of multiple rslo clones, we identified a specific sequence variation of 81 nucleotides, which is either absent from or present at the N-terminal region of a putative Ca2+-sensing domain of the channel. Transcripts containing(More)
BACKGROUND Gastric epithelial dysplasia (GED) can be morphologically categorized into adenomatous and foveolar types. To date, there have been few studies on the clinical characteristics of GEDs according to the morphologic types. Therefore, we here aimed to elucidate the clinicopathologic characteristics of patients with GED and the long-term follow-up(More)
BACKGROUND Endoscopic ultrasonography (EUS) is a valuable imaging tool for evaluating subepithelial lesions in the stomach. However, there are few studies on differentiation between gastrointestinal stromal tumors (GISTs) and benign mesenchymal tumors, such as leiomyoma or schwannoma, with the use of EUS. In addition, there are limitations in the analysis(More)
BACKGROUND/AIMS Globus is a persistent or intermittent non-painful sensation of a lump or foreign body in the throat. Given the benign nature of the condition and the association of gastroesophageal reflux disease, empirical therapy with proton pump inhibitor seems reasonable for patients with typical globus. The aim of this study was to investigate the(More)
Tumors of the gastric cardia are among the most technically difficult lesions to remove by endoscopic submucosal dissection (ESD). This study aimed to evaluate the therapeutic outcomes of ESD in gastric cardia tumors according to clinicopathologic characteristics, and to assess the predictive factors for incomplete resection. We conducted a retrospective(More)
which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited. Helicobacter pylori infection is recognized as an important contributor to non-ulcer dyspepsia, peptic ulcer disease, gastric mucosa-associated lymphoid tissue (MALT) lymphoma, and gastric cancer. Although the incidence(More)
BACKGROUND/AIMS Helicobacter pylori eradication therapy has been used as a first-line treatment for H. pylori-positive gastric mucosa-associated lymphoid tissue (MALT) lymphoma. However, the management strategy for H. pylori-negative MALT lymphoma remains controversial. Therefore, the aim of this study was to examine the success rate of each treatment(More)
BACKGROUND/AIMS Magnifying endoscopy with narrow band imaging (ME-NBI) is a useful modality for the detailed visualization of microsurface (MS) and microvascular (MV) structures in the gastrointestinal tract. This study aimed to determine whether the MS and MV patterns in ME-NBI differ according to the histologic type, invasion depth, and mucin phenotype of(More)
Open Access Endoscopic mucosal resection (EMR) and endoscopic sub-mucosal dissection (ESD) are curative techniques for gastric neoplasm; ESD has advantages over EMR regarding en bloc resection of large-sized lesions and submucosal fibrosis. Although ESD is widely considered a safe technique, complications including bleeding and perforation remain major(More)
