In this contribution,inspired by the excellent resource management and material transport function of leaf veins,the electrical transport function of metallized leaf veins is mimicked from the material transport function of the vein *** electroless copper plating on real leaf vein networks with copper thickness of only several hundred nanometre up to several micrometre,certain leaf veins can be converted to transparent conductive electrodes with an ultralow sheet resistance 100 times lower than that of state-of-the-art indium tin oxide thin films,combined with a broadband optical transmission of above 80%in the UV–VIS–IR ***,the resource efficiency of the vein-like electrode is characterized by the small amount of material needed to build up the networks and the low copper consumption during *** particular,the high current density transport capability of the electrode of>6000 A cm^−2 was *** superior properties of the vein-like structures inspire the design of high-performance transparent conductive electrodes without using critical materials and may significantly reduce the Ag consumption down to<10%of the current level for mass production of solar cells and will contribute greatly to the electrode for high power density concentrator solar cells,high power density Li-ion batteries,and supercapacitors.

TIPSS for variceal hemorrhage after living related liver transplantation:A dangerous indication

引用

World Journal of Gastroenterology 2006年第3期12卷 493-495页

The introduction of transjugular intrahepatic portalsystemic stent-shunt （TIPSS） has been a major breakthrough in the treatment of portal hypertension, which has evolved to a large extent, into a routine procedure. A 21-year-old male patient with progressive graft fibrosis/cirrhosis requiring TIPSS for variceal hemorrhage in the esophagus due to portal hypertension was unresponsive to conventional measures two years after living related liver transplantation （LDLT）. Subsequently, variceal hemorrhage was controlled, however, liver function decreased dramatically with consecutive multi organ failure. CT scan revealed substantial necrosis in the liver. The patient underwent successful ＂high urgent＂ cadaveric liver transplantation and was discharged on postoperative d 20 in a stable condition.
