background: several large clinical trials and meta-analyses have shown about 20% failure to eradicate helicobacter pylori ( h. pylori ), necessitating investigations for second-line treatments. the aim of this study was to evaluate the effects of clarithromycin-containing quadruple regimen after nitroimidazole-containing quadruple therapy failure. methods: thirty two patients who had failed 10-...

Surface-enhanced Raman scattering or surface-enhanced Raman spectroscopy (SERS) is a promising detection technology, and has captured increasing attention. Silver nanowires were synthesized using a rapid polyol method and optimized through adjustment of the molar ratio of poly(vinyl pyrrolidone) and silver nitrate in a glycerol system. Ultraviolet-visible spectrometry, X-ray diffraction, and tr...

The current study was conducted to investigate the prevalence of Salmonella spp. in turkey and to determine the antimicrobial resistance pattern of the isolated Salmonellae. Two hundred and fifty turkeys were randomly selected for cloacal soab samples preparation, and the samples were investigated for Salmonella isolation. Identification of the isolated Salmonella was performed using standard b...

  Background: The effectiveness of classic standard triple therapy regimen of helicobacter pylori (H. pylori) eradication has decreased to unacceptably low levels, largely related to development of resistance to metronidazole and clarithromycin. Thus successful eradication of H. pylori infections remains challenging. Therefore alternative treatments with superior effectiveness and safety should...

AIM To investigate morphological changes in Enterocytozoon bieneusi and the duration of symptomatic relief after combination treatment with furazolidone and albendazole in AIDS patients. METHODS Four severely immunocompromised AIDS patients with symptomatic E bieneusi infection of the gut received an 18 day course of combined furazolidone and albendazole (500 + 800 mg daily). All patients wer...

introduction: helicobacter pylori infections occur in about 50% of the world population and have a main role in the creation of peptic ulcer and its related cancer. we sought to evaluate the effectiveness of two treatment regimens on the eradication of helicobacter pylori and its complications among peptic ulcer patients. materials and methods: by a clinical trial, patients with peptic ulcer sh...

BACKGROUND When metronidazole is used in bismuth-based or proton pump inhibitor-based triple therapy, the cure rate of Helicobacter pylori is usually high. However, metronidazole-resistant H. pylori strains, which are increasing in frequency, are a major cause of failed H. pylori eradication. AIM To evaluate the efficacy of non-metronidazole containing bismuth-based triple therapy for H. pylo...
