Background Intussusception secondary to pathologic lead points (PLPs) is a potential surgical emergency and almost all cases need surgery. The aim of this study was to evaluate the clinical manifestations, physical examinations and surgical outcomes of secondary intussusception (SI) caused by PLPs, as well as to improve the diagnosis and treatment of PLPs in children and infants. Materials and methods...
For effective therapy for glioma, it is essential for chemotherapeutics to pass the blood-brain barrier to target glioma cells with little side effects to surrounding normal cells. In this study, we prepared doxorubicin-polybutylcyanoacrylate nanoparticles (Dox-PBCA-NP) and assessed its inhibition effects on glioma both in vitro and in vivo. Dox-PBCA-NP was prepared using the emulsion polymerization...
Considering the intrinsic safety of physical human-robot interaction, this paper proposes a compliance Cartesian position control of robot manipulator with series elastic actuations(SEA). High spring compliance introduces strong passive dynamics to improve safety. A kinetics model of manipulator was built to investigate the effect of applying driving forces. Without adopting the inverse dynamics,...
