Spike bundle contractions are multiphasic, resulting from asynchronous contraction and relaxation of uterine smooth muscle bundles [ 21].
In contrast, uterine tissue obtained from HFHC-fed rats during TNL produced asynchronous spike bundle contractions with sizeable fluctuations in amplitude.
In the first group of fiber bundles, tetanic contractions (200 Hz stimulation rate; 200 400 ms duration) were elicited at sarcomere lengths that were changed in steps of 0.1 μm to 0.4 μm, with 2 min rest between contractions.
The sinoatrial node uses calcium to cause a depolarizing signal transduction pathway from the atrium through right and left atrioventricular bundle which communicates contraction to the ventricles.
During dermis healing, fibroblasts generate stress fibers (weakly contractile actin bundles) to enable contraction [ 22].
This revealed that the bundles had weaker contractions in response to statins and the malaria drug chloroquine, just like normal muscles do—and that this effect worsened if more of each drug was used.
These are normal sinus rhythm, sinus bradycardia, ventricular tachycardia, sinus arrhythmia, atrial premature contraction, paced beat, right bundle branch block, left bundle branch block, atrial fibrillation and atrial flutter.
Ten types of ECG arrhythmias (normal beat, sinus bradycardia, ventricular tachycardia, sinus arrhythmia, atrial premature contraction, paced beat, right bundle branch block, left bundle branch block, atrial fibrillation and atrial flutter) obtained from MIT-BIH database were analyzed.
LN mediastinal lymph node, PVC premature ventricular contractions, RBBB right bundle branch block, SR sinus rhytm, VT ventricular tachycardia.
Diaphanous is a formin homology domain containing protein necessary for furrow ingression in metaphase, potentially important for bundling actin during actomyosin-driven contraction of metaphase furrows (Afshar et al., 2000).
