In this patient who previously had been cholecystectomized, instant extraction of giant residual gallstones was unsuccessful despite a large endoscopic sphincterotomy. Three days later, she developed colicky abdominal pain and vomiting. At laparotomy nine days after the(More)
The properties of self-assembled molecules may be tuned by sequentially coupling components on a gold surface, the molecular electronics toolbox of chemically reactive building blocks yielding molecular wires with diode-like current-voltage (I-V) characteristics. The bias for rectification in each case is dependent upon the sequence of electron-donating and(More)
