Background: The irritable bowel syndrome (IBS) is one of the most common chronic medical conditions. Various mechanisms, including altered gut flora and/or small bowel bacterial overgrowth, have been suggested to play a role in the development of gas-related symptoms aim of study. The clinical evidence of small intestinal bacterial overgrowth as an important etiology of irritable bowel syndrome...
In the present work, the effect of sintering parameters including sintering temperature, soaking time, and heating rate on densification, microstructure, and dielectrical properties of bismuth titanate (Bi4Ti3O12) ceramics were investigated. Bismuth titanate was synthesized by the solid state method and titanium oxide and bismuth oxide used as raw materials. X-ray diffraction (XRD) indicated, p...
BACKGROUND Curcumin and vanillin are the two useful compounds in food and medicine. Bismuth nitrate pentahydrate is an economical and ecofriendly reagent. METHOD Bismuth nitrate pentahydrate impregnated montmorillonite KSF clay and curcumin were subjected to microwave irradiation. RESULTS Microwave-induced bismuth nitrate-promoted synthesis of vanillin from curcumin has been accomplished in...
A bacteriological investigation performed on the biopsies of 1 30 patients with gastrointestinal disorders at the GI section of Imam Khomeini hospital concluded in the isolation of 100 cases of Helicobacler pylori. The antibacterial effects of bismuth salts alone and in synergy with tetracycline and metronidazole were evaluated on the basis of disc diffusion method on 5 randomly selected pu...
Gastrointestinal symptoms accompanying Lyme disease have not been considered in the treatment of Lyme patients yet. Here we examine the effect of ranitidine bismuth citrate (RBC) on motile and cystic forms of Borrelia burgdorferi in vitro, to determine whether it could cure this bacterial infection in the gastrointestinal tract. When motile forms of B. burgdorferi were exposed to RBC for 1 week...
The present study shows that feces samples of 14 human volunteers and isolated gut segments of mice (small intestine, cecum, and large intestine) are able to transform metals and metalloids into volatile derivatives ex situ during anaerobic incubation at 37 degrees C and neutral pH. Human feces and the gut of mice exhibit highly productive mechanisms for the formation of the toxic volatile deri...
synergistic effects of bismuth thiols and various antibiotics against pseudomonas aeruginosa biofilm
results the combination of bismuth ethanedithiol with ciprofloxacin showed synergistic inhibitory effect on the p. aeruginosa biofilm formation. the combination of bismuth ethanedithiol ciprofloxacin, ceftazidime and imipenem showed synergistic inhibitory effects on the biofilm formation. furthermore, the combination of bismuth ethanedithiol, imipenem and ceftazidime did not show any synergisti...
BACKGROUND AND PURPOSE The lens of the eye is sensitive to radiation. Children undergoing CT of the head and patients undergoing repeated CT scanning of the head are vulnerable to this complication. The purpose of this study was to test the ability of a heavy metal, bismuth, in reducing radiation to the lens of the eye during routine cranial CT. METHODS Both phantom and human studies were don...
