The linear dispersion relation in graphene 1 , 2 gives rise to a surprising prediction: the
resistivity due to isotropic scatterers, such as white-noise disorder 3 or phonons 4 , 5 , 6 , 7 , 8 , is …

Gastric cancer causes nearly one million deaths worldwide per year. Although Helicobacter
pylori infection is the main risk factor, in about 80% or more of gastric cancers, the molecular …

van der Waals (vdW) heterojunctions composed of two-dimensional (2D) layered materials
are emerging as a solid-state materials family that exhibits novel physics phenomena that …

Background: The success rate of currently recommended 7‐day triple therapy with a PPI plus
amoxicillin and clarithromycin has fallen into the unacceptable range. It is urgent to look for …

BACKGROUND & AIMS: We assessed the efficacy and safety of 4 bismuth-containing quadruple
regimens as empiric therapies for Helicobacter pylori infections in patients who did not …

Objective To evaluate the efficacy and tolerability of replacing tetracycline with amoxicillin in
bismuth quadruple therapy. Design Subjects who were infected with Helicobacter pylori and …

BACKGROUND: Poor expression of microRNAs (miRs) reportedly plays an important role in
gastric carcinogenesis. Large‐scale microarray assays have indicated that there is …

Objective Levofloxacin has been proposed to replace clarithromycin for Helicobacter pylori
treatment. Seven‐ and 10‐day fluoroquinolone triple therapies have generally failed to …

We have examined the impact of charged impurity scattering on charge carrier transport in
bilayer graphene (BLG) by deposition of potassium in ultrahigh vacuum at low temperature. …

Objectives: To compare the efficacy and safety of bismuth-containing quadruple therapy with
tetracycline or amoxicillin for rescue treatment ofHelicobacter pylori. Methods: The study …
