Characterization of polyethylene glycol-grafted polyethylenimine and superparamagnetic iron oxide nanoparticles (PEG-g-PEI-SPION) as an MRI-visible vector for siRNA delivery in gastric cancer in vitro and in vivo.

abstract：BACKGROUND:Peristaltic reflex does not fully explain the polarity of peristalsis. In the distal colon, we propose that the balance of circular muscle contraction proximal and distal to the pellet is a local reflex that predicts polarity of peristalsis. METHODS:Guinea pig distal colon segments were harvested, and fecal...
