Background: Non-alcoholic fatty liver disease (NAFLD) affects obese and non-obese individuals. However, mechanisms underlying non-obese non-alcoholic steatohepatitis (NASH) remain unclear.
Aims: To attempt to identify metabolic perturbations associated with non-obese and obese NAFLD using a lipidomics approach.
Chiral oxazaborolidinium ion (COBI)-catalyzed enantioselective nucleophilic addition reactions of aldimines using tributyltin cyanide and allyltributylstannane have been developed. Various α-aminonitriles and homoallylic amines were synthesized in high yield (up to 98%) with high to excellent enantioselectivity (up to 99% ee). A rational mechanistic model for the complex of COBI and aldimine is provided to account for these enantioselective reactions.

This acid was successfully applied as a catalyst for the highly enantioselective protonation/nucleophilic addition of diazoesters with carboxylic acids.

Cavernoma of the portal vein is defined as a formation of venous channels within or around a previously thrombosed portal vein. We experienced a 50-year-old woman who presented a huge hepatic mass with right upper quadrant dull pain. Abdominal computed tomography showed a huge sponge-like hepatic mass with cavernous transformation of portal vein along the common bile duct and common hepatic duct.
