Physiol. 43): H266–H276, 1998.—Triggered propagated contractions (TPCs) starting from damaged regions travel along multicellular cardiac muscle preparations.

متن کاملCa2+ waves during triggered propagated contractions in intact trabeculae.
Triggered propagated contractions (TPCs) starting from damaged regions travel along multicellular cardiac muscle preparations. We have reported that octanol (100 μM) inhibits TPCs. The inhibitory effect of octanol on propagation of TPCs could be due to an effect of octanol on Ca2+-induced Ca2+ release (CICR) mediated by Ca2+ diffusion inside the single cell or on the diffusion of Ca2+from cell ...
متن کاملSpontaneous and propagated contractions in rat cardiac trabeculae
Sarcomere length measurement by microscopic and laser diffraction techniques in trabeculae of rat heart, superfused with Krebs-Henseleit solution at 21 degrees C, showed spontaneous local sarcomere shortening after electrically stimulated twitches. The contractions originated in a region of several hundred micrometers throughout the width of the muscle close to the end of the preparation that w...
متن کاملAbsence of high amplitude propagating contractions in subjects with chronic spinal cord injury.
AIM To investigate the presence or absence of high amplitude propagating contractions (HAPC), as well as the other measures of colonic motility, in persons with spinal cord injury (SCI). METHODS Prolonged colonic ambulatory manometric studies were performed on 14 male volunteers: 8 with SCI (mean age, 59 ± 13 years; mean duration of injury, 13 ± 4 years) and 6 healthy able-bodied controls (me...
متن کاملEstimation and application of EMG amplitude during dynamic contractions.
The sections above have described an EMG amplitude estimator and an initial application of this estimator to the EMG-torque problem. The amplitude estimator consists of six stages. In the first stage, motion artifact and power-line interference are attenuated. Motion artifact is typically removed with a highpass filter. Elimination of power-line noise is more difficult. Commercial systems tend ...
