Is external abdominal oblique muscle ultrasonographic thickness changes an appropriate surrogate measure of electromyographic activity during isometric trunk contractions?
The negative correlations between EMG and USI measures as well as the great variability of these correlations across individuals suggest that USI is not a valid measures of EO muscle activity. USI thickness measures should be interpreted with great caution in research and clinical settings.
These data provide molecular and pharmacological evidence that LPS-induced late preconditioning against myocardial infarction is triggered by iNOS.
