The mechanical behavior of the papillary muscle was evaluated under baseline conditions at 2.5 mM [Ca.sup.2+] and after inotropic and lusitropic maneuvers: length-tension relationship, increases in extracellular [Ca.sup.2+] concentrations (to test their effects on myofilament machinery), and post-rest contraction (PRC), mainly related to SR storage and release capacity.
Under this condition, light scattering by precipitated sarcoplasmic proteins increases meat paleness, and the shrinkage of the myofilament lattice at a low pH increases reflection at myofibrillar surfaces, which will increase [L.sup.*] value, and decrease WHC values [7].
Carybdea marsupialis tentacle muscles lack Z-disks characteristic of a typical sarcomere structure but do possess light and dark myofilament bands.
In the DM group, SMC was arranged in disorder with irregular nucleus, massive dark staining chromatin, lots of cytoplasm lysis vacuoles distributed intracellularly, decreased dense bodies and myofilament, swollen mitochondria, vacuolar degeneration, and dissolution.
[115], it was observed that chronic CO exposure reduced the contraction of single rat ventricular myocyte due to the decrease of both systolic [Ca.sup.2+] release and myofilament [Ca.sup.2+] sensitivity.
Repopulating decellularized mouse hearts with human iPSC-derived multipotential cardiovascular progenitor cells showed signs of CM differentiation, proliferation, and myofilament formation [131].
The electromechanical model consisted of electrophysiological and myofilament dynamics model coupled by [Ca.sup.2+] transient.
