anger, joy, surprise, and sadness) utilizing MR imaging.#Joyful expressions caused a reduction in muscle length to 85.6% of its original length and anincrease in width (103.4%), thickness (108.4%), and facial angle (2.72掳) when compared to that in repose, suggesting isotonic contraction. ...
We present data showing that (1) most of the early strength loss results from a failure of excitation-contraction coupling and (2) a slow loss of contractile protein in the days after injury prolongs the recovery time.关键词: Animals Humans Muscle, Skeletal Wounds and Injuries Muscle Proteins ...
Thus, it was possible to establish the following inclusion criteria in a complementary way: (a) studies comparing the EMG activity of pectoralis major muscle of BP and OP; (b) EMG was recorded during the same motion and the same phase of contraction (e.g., concentric phase), so the ...
Interestingly, we observed a significant enrichment for genes with terms related to muscle contraction (e.g., TTN (12% of COIs; FDR-adjusted p-value = 1.48 × 10−203), KCNJ11 (27% of COIs; FDR-adjusted p-value = 1.03 × 10−43), DYSF (11% of COIs; FDR-adjusted p-value = ...
An in-depth exploration of the structure and function of muscles, focusing on the skeletal muscle cell, its components, and the process of muscle contraction. It covers topics such as the role of myosin and actin, the function of tropomyosin and troponin, and the process of cross-bridge inter...
are also capable of differentiating into myofibroblasts10. The latter display distinctive features such as increased cell size, high alpha smooth muscle actin (α-SMA) expression, and the presence of microfilaments that supports cell contraction. Importantly, myofibroblasts secrete great amounts of ECM...
in both RNA-seq and qRT-PCR (Supplementary Fig.4). Gene ontology analysis of these datasets revealed that the genes linked to the proliferation and function of the salivary gland, including cell-cell adhesion, ion transport, neurotransmitter transport, muscle contraction, and cell chemotaxis, were...

The kinin-releasing activity was immunoabsorbed selectively by monoclonal antibodies to the characteristic COOH-terminal domain of cruzipain. To determine the hydrolysis steps that account for the kininogenase activity of cruzipain, we synthesized a fluorogenic peptide (o-aminobenzoyl-Leu-Gly-Met-Ile-Ser...
In vitro, but not in cells, both PKG1α and PKG1β, but not cAMP-dependent protein kinase-A, phosphorylate GKAP1 protein. Troponin-T is another anchoring protein for PKG1, but not PKG2; PKG1 may participate in the regulation of muscle contraction via phosphorylated troponin-I [1280]. ...
