BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2013203061 DESCRIPTION A 54-year-old woman was referred to our department for upper gastrointestinal (UGI) barium study because of heartburn story for 1 month before admission. Previous endoscopic upper gastro-oesophageal study revealed no pathology. Upright UGI barium st...

Nanocrystalline particles of barium hexaferrite has been prepared by the sol–gel auto- combustion method using iron and barium nitrate with a Ba:Fe molar ratio of 1:10. The effect of fuel such as citric acid and aspartic acid was investigated on the structure and magnetic properties of nanoparticles. The results revealed that the formation of barium hexaferritefine particles is influenced by mo...

BACKGROUND There have been results showing the influence of bolus viscosities and consistency on esophageal motility and transit. However, there is no description about the influence of two different viscous boluses on esophageal contractions, bolus transit and perception of transit. Our objective in this investigation was to evaluate the esophageal transit and contraction after swallows of two...

Eight new barium methylphosphonates were prepared and described. In dependence on pH, either barium hydrogen methylphosphonates or barium methylphosphonates can be formed. In the case of barium methylphosphonates, BaCH3PO3·3H2O crystallizes from the solution at room temperature and BaCH3PO3·H2O at a temperature above 65 °C. On heating, these hydrates form two anhydrous barium methylphosphonates...

BACKGROUND Real-time esophageal imaging is critical in avoiding esophageal injury. However, the safety of esophageal imaging with barium has not been specifically explored. METHODS Three hundred seventy consecutive patients underwent left atrial (LA) ablation of atrial fibrillation (AF) under conscious sedation. One hundred eighty-five patients (50%) underwent the ablation procedure with, and...

Since many dyspeptic patients are still investigated initially by radiology, a policy was initiated whereby all such patients were directly referred for combined simultaneous double-contrast barium meal and cholecystogram. This policy was aimed at reducing patient visits to hospital and increasing diagnostic yield. The results of 1,444 combined procedures are presented. Of these, 310 (25.5%) ha...

Nanostructured materials are not immune from surface segregation, as can be shown for solid samples made from nanosized BaFelz.2xCoxTix019 barium femte particles and a variety of free clusters. Both theory and experiment provide ample demonstration that very limited dimensions of very small clusters does not necessarily impart stability against surface and grain boundary segregation. In fact, w...

Although inflammatory polyposis of the colon is a recognized local complication of ulcerative colitis, giant inflammatory polyposis that totally obliterates the colonic lumen is uncommon, and most of the patients have been from Western countries. We report a Japanese man who had localized giant inflammatory polyposis that obstructed the retrograde flow of barium in a double-contrast barium enem...
