Umbilical artery Doppler waveform notching: is it a marker for cord and placental abnormalities?
Umbilical artery waveform notching appears to be a strong predictor of cord and placental abnormalities. This finding may have important clinical implications.
These data provide information about organization and properties of thiol-based redox control, whose use is increased with the increase in complexity of organisms. Our data also show an essential combined function of a set of thiol oxidoreductases, and of thiol-based redox regulation in general, in all living organisms.
