Does ultrasound-microbubble-mediated intercellular adhesion molecule-1 small interfering ribonucleic acid transfection attenuate neointimal formation after arterial injury in mice?
The nonviral ultrasound-microbubble delivery of siRNA ensures effective transfection into target arteries. ICAM-1 siRNA has the potential to suppress arterial neointimal formation. Transfection of siRNA can be beneficial for the clinical treatment of cardiovascular and other inflammatory diseases.
In cross-sectional analysis, infection with cagA-positive strains of H pylori was associated with a 1.75-fold increased risk of peptic ulcer disease. Longitudinal analyses revealed an 18.4- and 2.9-fold increased risk for duodenal ulcer and gastric ulcer, respectively. The proportion of PUD that is attributable to H pylori infection might be larger than previously believed.
