Dissolution behaviour of both 5, 5-diphenyl hydantoin sodium commonly known as dilantin sodium (DS) and its corresponding marketed capsule dilantin have been studied in aqueous as well as micellar media. Percentage dissolution of both DS and its marketed capsule are found to be low as expected in aqueous medium due to its very low solubility in water. However, their dissolution tendency is foun...

Cronkhite-Canada syndrome (CCS) is a rare non-familial disorder with multiple gastrointestinal polyps and ectodermal changes. Adenomatous and carcinomatous changes have been reported. Video capsule endoscopy is a useful non-invasive tool to reveal polypoid lesions of the gastrointestinal tract suspicious for malignancy. We report a case of a patient with CCS with excessively elongated intestina...

salinity of water and soil in arid and semi arid regions restricts the growth and yield of crops such as sesame. in order to evaluate yield and yield components of 43 lines and ecotypes of sesame (sesamum indicum l.) under saline condition (ec of irrigation water, 5.2 ds m-1) an experiment was carried out in randomize complete block design with three replications at salinity research station of...

[structure: see text] NMR diffusion measurements were used to probe the role of water molecules in a resorcinarene capsule in a CDCl(3) solution. It was found that the water/resorcinarene ratio affects both the chemical shift and the diffusion coefficient of the water molecules. From the NMR diffusion measurements we could conclude that the major species in the chloroform solution is the hexame...

For patients with swallowing difficulties the capsule can be opened and the contents swallowed directly with half a glass of liquid or after mixing the contents in a slightly acidic fluid e.g. fruit juice, yoghurt or in non carbonated water. The dispersion should be taken immediately or within 30 minutes. Alternatively patients can suck the capsule and swallow the pellets with liquid. The pelle...

Crystallization of N-cyclohexyl ammonium resorcinarene triflate from methanol results in a dimeric capsule capable of trapping two triflate anions and two methanol molecules within a 341 Å cavity while with 1,4-dioxane as a guest it forms a new larger dimeric capsule with volume of 679 Å encapsulating four 1,4-dioxane and four water molecules, resulting in packing coefficients of 0.75 and 0.67,...

BACKGROUND AND STUDY AIMS Delayed gastric emptying is a significant factor in incomplete small bowel capsule examinations. Gastric transit could be hastened by external magnetic control of the capsule. We studied the feasibility of this approach to improve capsule endoscopy completion rates. PATIENTS AND METHODS Prospective, single-center, randomized controlled trial involving 122 patients at...

In this study, one dimensional model is developed for capsule train flow in a horizontal pipe. Simulation model calculates the pressure drop of the flow of solid-water two-phase mixture inside the pipe. Through this model, effects of different suspension viscosity models and suspension to wall friction coefficients on the pressure drop of the capsule train flow are investigated. The simulation ...

Near-hatching embryonic little skates, Raja erinacea, are highly active within their egg capsules, displaying a characteristic tail beating, which pumps water through the capsule. We measured the metabolic rate of late-stage embryos to determine whether oxygen sufficient for the embryo’s needs will diffuse through the egg capsule, and to assess the energetic cost of tail beating. Metabolic rate...
