Cobalamin is a member of the B-group of vitamins and a cofactor for metabolic processes like nucleic acid synthesis, amino acid synthesis, and the citric acid cycle. Mammals are unable to synthesize cobalamin and therefore rely on adequate food intake. Cobalamin absorption is a complex process in the stomach, duodenum, and ileum, requiring a functional exocrine pancreas. Read More

Superficial neoplastic lesions of the digestive tract are usually asymptomatic, and often represent incidental findings on endoscopy. The Paris Classification was developed for the systematic evaluation of superficial lesions of the oesophagus, stomach and colon. The significance of this classification in clinical practice is that it allows the depth of invasion to be estimated. Read More

Background: Endoscopic submucosal dissection (ESD) is a complex endoscopic procedure, with high rates of adverse events and technical difficulties. To overcome that problem, many training centers published the importance of animal models for skill acquirement in ESD. However, no study has used the submucosal dissection depth (DSUB) as a parameter to evaluate the learning curve in ESD, which might be a relevant factor since an optimal resection plane is important to achieve a curative resection and avoid intraoperative complications.

The Luciferase Immuno Precipitation System (LIPS) enables the detection of specific serum antibodies by immunoprecipitation of recombinant antigens tagged with a luciferase reporter. Here we describe LIPS assays for the quantification of autoantibodies to the H+, K+-ATPase A (ATP4A) and B (ATP4B) subunits, two serological markers of autoimmune atrophic gastritis and pernicious anemia. In particular, we will describe the expression of luciferase-tagged recombinant ATP4A and ATP4B, their immunoprecipitation with test sera, the recovery and washing of immune-complexes with a protein-A coated resin, and the quantification of autoantibodies by addition of a luciferase substrate and the measurement of the light output from captured luciferase-tagged antigens.

Background: The incidence of biliary lithiasis is increased after bariatric surgery due to rapid weight loss [1]. Trans-oral endoscopic management in cases of common bile duct gallstone complication is not possible in patients with Roux-en-Y gastric bypass (RYGB) due to the modified anatomy. Access to the biliary tree after RYGB with a classical direct surgical approach of common bile duct and choledocoscopy can be used, but may be complicated in situations of acute cholangitis because of the fragility of common duct, or in cases of previous cholecystectomy.

Gastric cancers (GC) after eradication are difficult to diagnose even by magnifying narrow-band imaging (NBI) or blue laser imaging (BLI) endoscopy. Little is known with regard to non-magnifying (NM)-NBI/BLI for early GC so we examined the efficacy of NM-NBI/BLI for early GC diagnosis. We retrospectively analyzed the images of 29 small (≤ 1 cm) intramucosal GC that had been treated with endoscopic submucosal dissection and 137 benign depressed lesions (BDLs). Read More

Standard treatment options for patients with advanced gastric cancer (GC) offer limited efficacy and are associated with some toxicity, which necessitates the development of more effective therapies for improving the treatment outcomes for this disease. Immunotherapy involving immune checkpoint inhibitors (ICIs) which inhibit the programmed death 1 (PD-1)/programmed death ligand 1 interaction has emerged as a new treatment option. Nivolumab, a human IgG4 monoclonal antibody inhibitor of PD-1, has demonstrated promising clinical activity and induced durable responses in patients with advanced GC. Read More

Oral drug delivery is a more favored mode of administration because of its ease of administration, high patient compliance, and low healthcare costs. However, no oral protein formulations are commercially available currently due to the hostile gastrointestinal (GI) barriers resulting in insignificant oral bioavailability of macromolecular drugs.

Background/aims: TNF-related apoptosis-inducing ligand (TRAIL) is a novel and low-toxic anti-tumor drug used for various cancers. However, cancer cells usually develop mechanisms to acquire the resistance against TRAIL. Among these changes, dysregulation of microRNAs (miRNAs) usually occurs in cancer cells and is responsible for induction of drug resistance. Read More
