BACKGROUND AND AIMS: The usefulness of histological diagnosis of gastroesophageal reflux disease (GERD) is limited by poor specificity or sensitivity of available diagnostic tools. Recently, ultrastructural morphometry showed interstitial space dilation (ISD) to be a reliable sign of reflux disease. Aims of this study were to (a) search for a...

This study explored the relationship between vacuolating toxin and ammonia in the genesis of Helicobacter pylori-induced vacuolation in cultured human gastric cells and investigated the intracellular sites of toxin accumulation. Neutral red dye uptake and electron microscopy were used in the investigation of the respective roles of, and of the...

Until now, survival analysis of gastric mucinous cancers showed either no difference or an even worse prognosis than stage-adjusted non-mucinous tumours. In the pancreas and breast, mucinous cancers showing well-demarcated mucin deposits (muconodular pattern), expansile growth and predominance of MUC2 mucin are known to have a more favourable...

To investigate the role of genetic instability in the development of intestinal- and diffuse-type gastric cancers, six microsatellite loci were analysed in 98 carcinomas of the two main histotypes, at both early and advanced stages of progression, and in five preneoplastic lesions. RER+ phenotype frequency proved to be significantly higher (P =...
