Real-time inferior vena caval ultrasonography: normal and abnormal findings and its use in assessing right-heart function.

abstract：BACKGROUND:Thioredoxin 2 (Trx2) is a key mitochondrial protein that regulates cellular redox and survival by suppressing mitochondrial reactive oxygen species generation and by inhibiting apoptosis stress kinase-1 (ASK1)-dependent apoptotic signaling. To date, the role of the mitochondrial Trx2 system in heart failure ...
