Development of polycaprolactone grafts with improved physical properties and body stability using a screw extrusion-type 3D bioprinter.

Three-dimensional (3D) bioprinter including screw extruder was developed, and the polycaprolactone (PCL) grafts fabricated by screw-type and pneumatic pressure-type bioprinters were comparatively evaluated. The density and tensile strength of the single layers printed by the screw-type were 14.07% and 34.

Stylopine from Chelidonium majus inhibits LPS-induced inflammatory mediators in RAW 264.7 cells.

Stylopine is a major component of the leaf of Chelidonium majus L. (Papaveraceae), which has been used for the removal of warts, papillomas and condylomas, as well as the treatment of liver disease, in oriental countries. Stylopine per se had no cytotoxic effect in unstimulated RAW 264.
