CHANGES OF MUSCLE RELAXATION MANNER DURING GROWTH

Proteome Changes in Thai Indigenous Chicken Muscle during Growth Period

Proteomic profiling of the pectoralis muscle of Thai indigenous chickens during growth period was analyzed using two-dimensional gel electrophoresis (2-DE) and matrix assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF/MS). A total of 259, 161, 120 and 107 protein spots were found to be expressed in the chicken pectoralis muscles at 0, 3, 6 and 18 weeks of age, resp...

Altered performance of rat cardiac muscle follows changes in mechanical stress during relaxation.

We compared two sets of loading conditions for their effect on the mechanical performance of isolated rat trabecular muscle: (1) loading which approximated that of the intact ventricle; (2) nonphysiological afterloaded isotonic contractions. Improved performance, manifested by increased shortening and rate of shortening at constant load, was seen when lengthening occurred at light loads, as in ...

Relaxation phenomena during non-equilibrium growth

effect of progressive muscle relaxation technique on pain relief during labor

labor pain is a cause of stress and suffering; for which many women seek methods to relieve this pain. the aim of this study was to determine the effect of relaxation techniques on pain relief during labor. this study was carried out on 62 pregnant women referred to fatemieh hospital (hamadan, iran) during their labor. they were selected using convenience sampling and were divided randomly in t...

Myosin phosphorylation during contraction and relaxation of tracheal smooth muscle.

The role of myosin phosphorylation in regulating smooth muscle contraction has been investigated by quantitating the myosin phosphate content of tracheal smooth muscle frozen during contraction or relaxation. Myosin was purified from quick-frozen muscle samples with the aid of antibodies prepared against tracheal smooth muscle myosin, and the phosphate content was determined after separation of...
