Introduction: Proximal oesophageal stent deployment continues to provide challenges due to the proximity of the upper oesophageal sphincter and the associated subsequent complications such as globus sensation and stent migration. Patients with cervical oesophageal cancer have previously had limited stenting options available to them with a paucity of the literature describing the radiological technique for successfully placing these high-risk stents. In this paper, we present our experience using the Taewoong Niti-S CERVICAL Oesophageal Stent. Read More

Dieulafoy's lesion (DL) is a dilated aberrant submucosal vessel that erodes through the overlying epithelium in the absence of a primary ulcer. It is a known cause of gastrointestinal (GI) bleeding and commonly located in the lesser curvature of the stomach, but it is rare in the anal canal. We report a unique case of a middle-aged man presenting with lower GI bleeding secondary to an anal DL diagnosed by colonoscopy, managed successfully with endoscopic hemoclips. Read More

Crohn's disease with involvement of the esophagus, stomach and duodenum has a prevalence of 0.5% to 4% in symptomatic adult patients, but some studies have shown that these results may be underestimated, since upper gastrointestinal endoscopy is not performed routinely in the initial evaluation of the disease in adult patients, as it is in the pediatric population. In general, involvement of the upper gastrointestinal tract in Crohn's disease occurs concomitantly with involvement of the lower gastrointestinal tract. Read More

The application of high-throughput sequencing to retrieve multi-taxon DNA from different substrates such as water, soil, and stomach contents has enabled species identification without prior knowledge of taxon compositions. Here we used three minibarcodes designed to target mitochondrial COI in plankton, 16S in fish, and 16S in crustaceans, to compare ethanol- and tissue-derived DNA extraction methodologies for metabarcoding. The stomach contents of pygmy devilrays ( cf. Read More

The gastric bacterium causes a persistent infection that is directly responsible for gastric ulcers and gastric cancer in some patients and protective against allergic and other immunological disorders in others. The two outcomes of the -host interaction can be modeled in mice that are infected as immunocompetent adults and as neonates, respectively. Here, we have investigated the contribution of the immunomodulator VacA to -specific local and systemic immune responses in both models. Read More

We investigated effects of the application of a sulfur-modified organoclay (SMOC) at doses of 1%, 3% and 5% (w/w) on the geochemical fractionation of mercury (Hg) and its accumulation by pea and corn in a polluted floodplain soil. Soil Hg was fractionated sequentially to five operationally defined fractions as follows: F1: water soluble Hg; F2: "human stomach acid" soluble Hg; F3: organo-chelated Hg; F4: elemental Hg; and F5: Hg-sulfur-compounds/residual Hg. The high dosage of SMOC caused a decrease of Hg in F3 (18%) and F5 (36-63%), and 6. Read More
