Fluorinated polyimide derived from 2,2'-bis(3,4-dicarboxyphenyl) hexafluoropropane dianhydride (6FDA) and bis[4-(4-aminophenoxy) phenyl]sulfone (APPS) was synthesized to develop a novel membrane oxygenator combining excellent gas transfer and blood compatibility. The asymmetric gas exchange membranes of 6FDA-APPS made by a dry/wet process consisted

Parkinson's disease (PD) has classically been characterized by features of motor dysfunction, but these may manifest only after the nigrostriatal system has incurred significant damage. However, recent evidence suggests that cardiac sympathetic denervation occurs early on in PD. This may
