Comparison of the effect of clarithromycin triple therapy with or without -acetylcysteine in the eradication of : a randomized controlled trial.

Background: Whether adjunctive -acetylcysteine (NAC) may improve the efficacy of triple therapy in the first-line treatment of infection remains unknown. Our aim was to compare the efficacy of 14-day triple therapy with or without NAC for the first-line treatment of .

Material And Methods: Between 1 January 2014 and 30 June 2018, 680 patients with infection naïve to treatment were enrolled in this multicenter, open-label, randomized trial.

Self-Assembly Behavior of Diacetylenic Acid Molecules upon Vapor Deposition: Odd-Even Effect on the Film Morphology.

A series of linear carboxylic acids containing diacetylenic units at different positions along the chain (C H (C≡C) (CH ) COOH, n=7-11) were vacuum-deposited on clean silica substrates. The morphologies of the initial films after UV irradiation were studied. A clear odd-even effect on the morphology of the initial film was observed in that, depending on the spacer length between the diacetylenic unit and carboxyl head group, rings or dendrites of acid dimer layers were obtained.

Application of Helicobacter pylori stool antigen test to survey the updated prevalence of Helicobacter pylori infection in Taiwan.

Background And Aim: The reported prevalence of Helicobacter pylori infection in Taiwan was 54.4% in 1992. An updated prevalence of H.

Evaluation of surfactant flushing for remediating EDC-tar contamination.

Ethylene dichloride tar (EDC-tar) is a dense non-aqueous phase liquid (DNAPL) waste originated from the process of vinyl chloride production, with major constituents including chlorinated aliphatic and aromatic hydrocarbons. This study investigated the feasibility of Surfactant Enhanced Aquifer Remediation (SEAR) for treating EDC-tar contaminated aquifers. Initial experiments explored the potential to enhance the apparent solubility of EDC-tar using single or mixed surfactants.
