Subsequent to the calcium release into the myoplasm
, the sarcoendoplasmic reticulum ATPase (SERCA) works to sequester calcium back into the sarcoplasmic reticulum, again via ATP dependent enzymatic activity.
The inorganic phosphate enters the myoplasm
before moving into the SR, where the [P.
We obtained that the resistance of the myoplasm ([r.
In the ideal case, the measured input resistance consists of the resistance of the closest cellular myoplasm, the resistance of contact membrane and the resistance of cellular membrane connected in parallel (Fig.
The mechanisms leading to the PSS-susceptibility crisis involve a high concentration of free calcium in the myoplasm
released by a faulty membrane system in calcium storing organelles including sarcoplasmic reticulum (14).
Changes in both voluntary and electrically evoked muscle performance during the SSE are likely not to be attributed to an increase in the myoplasm
of metabolites, like phosphate and hydrogen ions, since the duration of the jump (0.
The discovery of an animal model for malignant hyperthermia, a certain breed of pigs, led to the realisation that the essential biochemistry of malignant hyperthermia was increased calcium in the myoplasm
To make the muscle contract and relax, calcium goes from the sarcoplasmic reticulum to the myoplasm and back.
The sonic muscles of toadfish and rattlesnakes pump calcium out of the myoplasm 50 times faster than the locomotor muscles do, Rome's group reports in the July 23 Proceedings of the National Academy of Sciences (PNAS).
The B-line presumptive muscle cells of ascidian embryos have extensive potential for self-differentiation dependent on determinants prelocalized in the myoplasm
of fertilized eggs (2).
Normal distributions of myoplasm
were altered in ascidian embryos by using a microcompression technique (Whittaker, 1980).
occulta may be due to the absence of a protein that is recognized by a vertebrate intermediate filament antibody (NN18) localized in the myoplasm
