The aim of this study was to evaluate the efficacy of levofloxacin and rifaximin based quadruple regimen as first-line treatment for Helicobacter pylori infection. A prospectively randomized, double-blinded, parallel group, comparative study was performed. Three hundred consecutive H. pylori positive patients were randomized to receive: omeprazole, amoxicillin, clarithromycin (OAC); omeprazole,...

Inspired by the recent work of El Bachraoui, we present some new q-supercongruences on triple and quadruple sums basic hypergeometric series. In particular, give a q-supercongruence modulo fifth power cyclotomic polynomial, which is q-analogue sum Van Hamme’s supercongruence (G.2).

OBJECTIVES The aim of this study was to estimate the frequency of triple- and quadruple-resistant Helicobacter pylori isolated in Germany, to characterize those isolates molecular genetically and to identify risk factors for the development of multiresistance. METHODS Antimicrobial susceptibility to metronidazole, clarithromycin, amoxicillin, tetracycline, ciprofloxacin/levofloxacin and rifam...

in this paper, experimentally derived correlations of heat transfer and pressure drop are used in a pareto based multi-objective optimization (moo) approach to find the best possible combinations of heat transfer and pressure drop of tio2-water nanofluid flow in tubes fitted with multiple twisted tape inserts in different arrangement. in this study there are four independent design variables: t...

background the prevalence of peptic ulcer disease in hemodialysis patients is more than the general population. they are also more prone to complications including upper gastrointestinal bleeding. the aim of this study was to compare the efficacy of 14 days hybrid regimen with 14 days triple therapy for helicobacter pylori ( h . pylori ) eradication in hemodialysis patients. methods forty hemod...

BACKGROUND/AIMS Several rescue therapies have been recommended to eradicate Helicobacter pylori infection in patients with a failure of first-line eradication therapy, but they still fail in more than 20% of cases. The aim of this study was to evaluate the efficacy and safety of levofloxacin, metronidazole, and lansoprazole (LML) triple therapy relative to quadruple therapy as a second-line tre...

Triple encryption is a cascade of three block cipher evaluations with independent keys, in order to enlarge its key size. This design is proven secure up to approximately 2κ+min{κ/2,n/2} queries (by Bellare and Rogaway, EUROCRYPT 2006, and Gaži and Maurer, ASIACRYPT 2009), where κ denotes the key size and n the block length of the underlying block cipher. On the other hand, the best known attac...

background: the eradication of helicobacter pylori infection, commonly prevailing in the stomach, has been important since its introduction. adequate preparations should be made in finding alternatives when faced with first-line treatment failures. currently, ideal second-line treatments are indistinct and varied among countries as result of different antibiotic resistance patterns. we aimed to...

childrenwith helicobacter infection need treatment. the aim of treatment is elimination of h.pylori. most patients with this infection are asymptomatic and without peptic disease. treatment and management of these patients are controversy. conventional treatment: the best treatment for h. pylori eradication regimens should have cure rates of at least 80%, be without major side effects, and indu...
