AIM To compare the healing effects of vonoprazan and lansoprazole on gastric ulcers induced by endoscopic submucosal dissection (ESD). METHODS Data were obtained from a total of 26 patients. Fourteen patients were randomized to the vonoprazan group and 12 were randomized to the lansoprazole group. Patients were administered either 20 mg vonoprazan or 30 mg lansoprazole per day after ESD. Endo...

Based on the idea of alloying welding seams, a series of Zn-xAl filler metals was calculated and designed for joining Mg/Al dissimilar metals by gas tungsten arc (GTA) welding. An infrared thermography system was used to measure the temperature of the welding pool during the welding process to investigate the solidification process. It was found that the mechanical properties of the welded join...

In this study, the corrosion behavior of Mg-Zn-Se and Mg-Zn-Cu alloys was investigated to evaluate their corrosion behavior related to use as implantable biomaterials. The corrosion behavior of these alloys and a commercially available Mg-Zn alloy were examined using static solution electrochemical testing, dynamic solution gravimetric testing, ion leaching testing, and microscopic evaluation. ...

BACKGROUND Several randomized controlled trials (RCTs) have compared endoscopic and symptomatic relapses in patients with erosive gastroesophageal reflux disease (GERD). We have summarized current evidence for rabeprazole 10 or 20 mg once daily for GERD maintenance treatment over 1 or 5 years. METHODS MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials were searched, throu...

The ground and many excited states of the Mg(+)He van der Waals molecular system have been explored using a one-electron pseudopotential approach. In this approach, effective potentials are used to consider the Mg(2+) core and the electron-He effects. Furthermore, a core-core interaction is included. This has reduced the number of active electrons of the Mg(+)He, to be considered in the calcula...

Five young adult Rhesus monkeys were included in this study. The weight of the animals ranged from 3.4 to 4.0 kg, with a mean of 3.6 kg. Each animal was restrained and anesthetized with ketamine HC1 at 25 mg/kg IM. An intravenous fluid of 5% dextrose and water with 1/4 normal saline was initiated and profused at a maintenance rate. Each monkey received intranasal midazolam (VersedTM, Roche Phar...

OBJECTIVES To evaluate the efficacy and safety of 2.5 mg and 5 mg mifepristone during 3 months for the treatment of uterine fibroids before surgery. DESIGN Multicenter randomized clinical trial. LOCATIONS Eusebio Hernández Hospital, Havana, Cuba and the Alemán Hospital, Managua, Nicaragua. SUBJECTS Included in the study were 146 women with symptomatic uterine fibroids. TREATMENT GROUP I...
