BACKGROUND The purpose of the present paper was to evaluate the efficacy and tolerability of amoxicillin-clavulanate and tetracycline-based quadruple therapy as an alternative second-line treatment for H. pylori infection. METHODS The study subjects consisted of 54 patients infected with H. pylori, in whom initial triple therapy had failed. Subjects were randomized to receive the following 7-...
Fifty three patients with endoscopically proven duodenal ulceration have cooperated in a clinical trial to compare the ulcer healing effect of tripotassium dicitrato bismuthate (TDB) at standard dosage administered either twice or four times daily. No statistically significant difference has been found to exist between ulcer healing in the two groups at 4 weeks (72% and 67%, P = 0.944) or at 8 ...
We fabricate a saturable absorber mirror by coating a graphene- film on an output coupler mirror. This is then used to obtain Q-switched mode-locking from a diode-pumped linear cavity channel waveguide laser inscribed in Ytterbium-doped Bismuthate Glass. The laser produces 1.06 ps pulses at ~1039 nm, with a 1.5 GHz repetition rate, 48% slope efficiency and 202 mW average output power. This perf...
In the present work, bismuth oxychloride nanoparticles-a light harvesting semiconductor photocatalyst-were synthesized by a facile hydrolysis route, with sodium bismuthate and hydroxylammonium chloride as the precursor materials. The as-synthesized semiconductor photocatalysts were characterized using X-ray diffraction analysis, Fourier transform infra-red spectroscopy, Raman spectroscopy, Fiel...
