Hibernation torpor provides an excellent model of natural tolerance to ischemia.We have previously shown that massive global SUMOylation occurs during hibernation torpor in ground squirrels.We have also shown that overexpression of Ubc9, SUMO-1, or SUMO-2/3 provides protection against ischemic damage in cell lines and cortical neurons exposed to ox
Extrahepatic bile duct cancer is an uncommon disease, wx gloves and few cases are curable by surgery.We report a case of extrahepatic biliary cystadenocarcinoma (BCAC) associated with atrophy of the left hepatic lobe.A 54-year old male was admitted with painless obstructive jaundice and a hepatic palpable mass noticed one month before presentation.
