BaPb1−xBixO3 (BPBO) bismuthate, showing high TC superconductivity for 0.05 < x 0.35, is an archetypal system studying the complex inhomogeneity of perovskite lattice favoring emergence quantum coherence, called superstripes phase. Local fluctuations, detected by EXAFS; nanoscale stripes, electron microscopy; and two competing crystalline structures, diffraction, are known to characterize sup...

objective studies on the effect of various antiepileptic drugs on serum lipids show contradictory results. we aimed to find the effect of phenobarbital and sodium valproate monotherapy on serum lipid profile and liver function tests in epileptic children. materials & methods this cohort study was conducted in amirkola children hospital. one hundred and ten children with epilepsy were included i...

We review the remarkable properties, including superconductivity, charge-densitywave ordering, and metal-insulator transitions, of leadand potassium-doped barium bismuthate. We discuss some of the early theoretical studies of these systems. Our recent theoretical work, on the negative-U , extended-Hubbard model for these systems, is also described. Both the largeand intermediate-U regimes of th...

The use of tripotassium dicitrato bismuthate (TDB) has been suggested recently for cimetidine resistant duodenal ulcers. This study compares the efficacy of TDB with two different cimetidine dosages in the treatment of duodenal ulcer patients who failed to respond to an eight week therapy with H2-blockers. Fifty two patients (40 men, 12 women) were randomly allocated to one of the following thr...

BACKGROUND/AIMS Retreatment after initial treatment failure for Helicobacter pylori is very challenging. The purpose of this study was to evaluate the efficacies of moxifloxacin-containing triple and bismuth-containing quadruple therapy. METHODS A total of 151 patients, who failed initial H. pylori treatment, were included in this retrospective cohort study. The initial regimens were standard...

a simple and efficient one-pot method for the preparation of aromatic iodides has been developed by sequential diazotization–iodination of aromatic amines employing sodium nitrite and sodium iodide in the presence of acidic ionic liquid n-methyl-2-pyrrolidonum hydrosulfate ([h-nmp]hso4). the diazonium salts that are formed by this ionic liquid are stable at room temperature and react rapidly wi...

thiopental sodium is an ultra short-acting barbiturate. due to its redistribution characteristic, its first injection has a short term effect. in order to elongate its anesthesia duration, more injections are needed. as these additional injections extend the recovery length , weaken respiration and causes other dangerous effects; its repeated use is considered unsafe. citicoline is a natural su...
