The various light and scanning electron microscopic appearances of barium sulphate in smears and in histopathological lesions in sections are illustrated. One type of barium sulphate (E-Z-HD) includes much larger, bright birefringent particles and has very different appearances from other widely used types. Such larger particles in sections were not originally suspected to be barium sulphate an...

We demonstrate control of the surface plasmon polariton wavevector in an active metal-dielectric plasmonic interferometer by utilizing electrooptic barium titanate as the dielectric layer. Arrays of subwavelength interferometers were fabricated from pairs of parallel slits milled in silver on barium titanate thin films. Plasmon-mediated transmission of incident light through the subwavelength s...

BACKGROUND The use of high-density barium sulfate was recommended by the Japan Society of Gastroenterological Cancer Screening (JSGCS) in 2004. We evaluated the diagnostic validity of gastric cancer screening that used high-density barium sulfate. METHODS The study subjects were 171 833 residents of Osaka, Japan who underwent gastric cancer screening tests at the Osaka Cancer Prevention and D...

Rectal bleeding often heralds serious colonic disease. The literature suggests that colonoscopy is superior to barium enema plus sigmoidoscopy, although no good comparative studies exist. Seventy one patients with overt rectal bleeding had prospectively flexible sigmoidoscopy, double contrast barium enema and colonoscopy completed independently. Against the gold standard, the sensitivity and sp...

Introduction: It’s a rare report about intestinal obstruction caused by barium retention after small bowel radiography of oral barium. An 83-year-old woman was admitted for bile duct cancer with metal stent and incomplete intestinal obstruction .The patient ever did upper gastrointestinal barium meal examination which showed the mucosa of descending part of duodenum was unclear and contrast med...

BACKGROUND AND AIMS In hemostasis for colonic diverticular bleeding, the incidence of recurrent bleeding is higher in deep colonic diverticulum than in shallow. We aimed to improve and evaluate barium impaction therapy using an enteroscopic overtube with balloon. PATIENTS AND METHOD We performed barium impaction therapy in three patients with a diagnosis of deep colonic diverticular bleeding....

Timed barium esophagogram (TBE) is a simple and objective method for assessing the esophageal emptying. The technique of TBE is similar to usual barium swallow with some modifications, which include taking multiple sequential films at pre-decided time interval after a single swallow of a fixed volume of a specific density barium solution. While many authors have used height and width of the bar...

Single-molecule fluorescence imaging (SMFI) of gas-phase ions has been proposed for “barium tagging,” a burgeoning area research in particle physics to detect individual barium daughter ions. Th...

Barium Oxide(BaO) nanoparticles were synthesized by simple co-precipitation method and were investigated by the catalytic activity of synthesized barium oxide nanopaticles was enumerated by epoxidation of styrene. The reaction was carried out and the product was obtained at higher efficiency. Particularly, the photocatalytic efficiency was estimated by degradation of Rhodamine-B (RhB) dye using...
