The role of tropomyosin isoforms and phosphorylation in force generation in thin-filament reconstituted bovine cardiac muscle fibresSpringer Science and Business Media LLC - Tập 31 - Trang 93-109 - 2010
Xiaoying Lu, David H. Heeley, Lawrence B. Smillie, Masataka Kawai
The thin filament extraction and reconstitution protocol was used to investigate the functional roles of tropomyosin (Tm) isoforms and phosphorylation in bovine myocardium. The thin filament was extracted by gelsolin, reconstituted with G-actin, and further reconstituted with cardiac troponin together with one of three Tm varieties: phosphorylated αTm (αTm.P), dephosphorylated αTm (αTm.deP), and d...... hiện toàn bộ
Myosin polymorphism in muscles of the toadfish,Opsanus tauSpringer Science and Business Media LLC - Tập 4 - Trang 223-232 - 1983
F. Huriaux, F. Lefebvre, B. Focant
The superfast swimbladder muscle ofOpsanus tau differs from the corresponding fast skeletal muscle not only by its greater sarcoplasmic reticulum and parvalbumin content but also by a genuine myosin LC2. The study of light chains has been extended here to other striated muscles. Myosins from fast (trunk muscle), superfast (swimbladder muscle), slow (lateral-line muscle) and cardiac (ventricle musc...... hiện toàn bộ
Nonlinear summation of contractions in striated muscle. I. Twitch potentiation in human muscleSpringer Science and Business Media LLC - Tập 7 - Trang 11-17 - 1986
J. Duchateau, K. Hainaut
The adductor pollicis of intact man was electrically stimulated via its motor nerve, with series of two supramaximal pulses delivered at various intervals. Muscle surface action potential, myogram and corresponding first derivative (dPt/dt) were recorded under isometric conditions. When two stimuli are delivered at intervals shorter than 150 ms a more-than-linear summation, or potentiation, is obs...... hiện toàn bộ
Determinants of maximal oxygen consumptionSpringer Science and Business Media LLC - Tập 44 - Trang 73-88 - 2022
Peter D. Wagner
This article lays out the determinants of maximal O2 consumption (VO2max) achieved during high intensity endurance exercise. It is not a traditional topical review but rather an educational essay that intertwines chance observations made during an unrelated research project with a subsequent program of stepwise thought, analysis and experimentation to reveal how O2 is delivered to and used by the ...... hiện toàn bộ
Activation of caspase 3, 9, 12, and Bax in masseter muscle of mdx mice during necrosisSpringer Science and Business Media LLC - Tập 28 - Trang 243-247 - 2007
A. Honda, S. Abe, E. Hiroki, H. Honda, O. Iwanuma, N. Yanagisawa, Y. Ide
The mdx mouse, a model of muscular dystrophy, lacks dystrophin, a cell membrane protein. It is known that the lack of dystrophin causes muscle fiber necrosis from 2 weeks after birth, and the majority of necrotic muscle fibers are replaced by regenerated muscle fibers by 4 weeks after birth. A recent study indicated the possibility that mitochondria-mediated intracellular stress, a phenomenon simi...... hiện toàn bộ
