Annular pancreas divisum is a very rare congenital anomaly involving the coexistence of an annular pancreasand pancreatic divisum in one pancreas, and showing characteristic radiologic findings of ring-like pancreatictissue surrounding the second portion of the duodenum and no evidence of connection between ventral and dorsalductal systems. We described the radiologic findings of annular pancreas divisum, diagnosed by hypotonicduodenography, CT and ERCP.

The fabrication of a nano-porous polyoxazoline stamp tip for scanning probe nanolithography has been reported, and the patterning of nanometer scale high-molecular weight proteins at ultra-fast speed demonstrated using the stamp tip. A nanoporous polymer-coated silicon tip was constructed using ring opening polymerization of 2-methyl-2-oxazoline on the surface of the tip employing a simple solution polymerization method. Because polyoxazoline is a hydrophilic and biocompatible polymer, these tips can easily absorb and release water-based biomolecules via their pores. Using dip-pen nanolithography, the patterning of Human IgG and PSA proteins using these stamp tips has been demonstrated. The results showed that protein nano-patterns can be generated at least five times faster with this method than with a conventional silicon tip.
