Aim: To investigate the eradication therapy, mucosal protective effect and its mechanism of compound bismuth and magnesium granules on Helicobacter Pylori (H. pylori) infection in KM mice. Methods: HP infection model in KM mice was established by gavage with HP standard strain NCTC 11637. KM mice were randomly divided into five groups: the normal control group, the model group, the compound bis...

Low cost disposable working electrodes are specifically desired for practical applications of electrochemical detection considering maturity of electrochemical stations and data collection protocols. In this paper double-sided conductive adhesive carbon tape with nanostructure was applied to fabricate disposable working electrodes. Being supported by indium tin oxide glass, the prepared carbon ...

INTRODUCTION One of the uses of white mineral trioxide aggregate (MTA) is as an apical barrier in immature teeth. Although this treatment has been reported to have high success rates, a number of cases of discoloration have been noted. The aim of this research was to investigate the color stability of white MTA in contact with various solutions used in endodontics. METHODS The change in color...

This randomized controlled study aimed to evaluate whether adding bismuth to the standard first-line triple therapy could improve the eradication rate of Helicobacter pylori. A total of 162 patients with Helicobacter pylori infection were randomly assigned to either the 7-day triple therapy group (RAK regimen: rabeprazole 20 mg, amoxicillin 1 g, and clarithromycin 500 mg bid; n = 81) or the bis...

Radiopacity is a critical property of materials that are used for a range of radiological applications, including the development of phantom devices that emulate the radiodensity of native tissues and the production of protective equipment for personnel handling radioactive materials. Three-dimensional (3D) printing is a fabrication platform that is well suited to creating complex anatomical re...

bismuth sulfide nano-rods and nano-flowers were synthesized via a hydrothermal reaction at a relatively low temperature. thioglycolic acid is used as sulfur source and capping agent simultaneously. bi2s3 nanostructures were then added to acrylonitrile-butadiene-styrene (abs) copolymer. the thermal stability behavior of abs filled with bismuth sulfide nano-rods were investigated by thermogravime...

The calorimetric and fluorescence properties of Bismuth Germanate are discussed and compared to those of NaI(TI1). Results on the energy resolution of BGO are presented for energies up to 50 MeV; the energy and position resolution are studied by Montecarlos at higher energies. The performance of a 4x BGO e.m. calorimeter is compared to that of NaI and is specified for a compact fieldless calori...

BACKGROUND Due to increasing antimicrobial resistance, a bismuth-based quadruple regimen has been recommended as an alternative first-line therapy for Helicobacter pylori (H pylori) eradication. However, different results are varied greatly and the availability of bismuth was limited in some countries. We assessed the efficacy and safety of 14-day berberine-containing quadruple therapy as an al...
