Do intra-QRS spectral changes accompany ST segment changes during episodes of myocardial ischemia?
Intra-QRS time-frequency analysis using the continuous wavelet transform can identify a spectral signature corresponding to myocardial ischemia in the range 24-80Hz. Intra-QRS spectral analysis has the potential for many clinical applications.
TNF-alpha protects rat hepatocytes from normal but not iron-loaded rats from oxidative stress. The protection may be due to an induction of the ferritin synthesis.
