High-mobility group box-1 in ischemia-reperfusion injury of the heart.

abstract：BACKGROUND:The Fick principle (cardiac output = oxygen uptake ( O2)/systemic arterio-venous oxygen difference) is used to determine cardiac output in numerous clinical situations. However, estimated rather than measured O2 is commonly used because of complexities of the measurement, though the accuracy of estimation re...
