Skeletal muscle mTORC1 regulates neuromuscular junction stability

Journal of Cachexia, Sarcopenia and Muscle, 2020
Background Skeletal muscle is a plastic tissue that can adapt to different stimuli. It is well established that Mammalian Target of Rapamycin Complex 1 (mTORC1) signalling is a key modulator in mediating increases in skeletal muscle mass and function ...

Metabolic heterogeneity of muscle fibres [PDF]

Journal of Experimental Biology, 1985
ABSTRACTMammalian skeletal muscle is an extremely heterogeneous tissue. Its diversity results from a spectrum of fibres which are metabolically suited to a wide range of functional demands. As judged from enzyme activity analyses of single fibres, the metabolic properties of fibres belonging to the same motor unit are similar or identical. It is likely,

Jitter in the muscle fibre. [PDF]

Journal of Neurology, Neurosurgery & Psychiatry, 1990
Direct stimulation of muscle fibres with a regular 10 Hz rate, three computer generated random rhythms and a sequence of voluntary discharges was used to quantify the interdischarge interval (IDI) dependent jitter due to velocity recovery function (VRF).

Noninvasive Estimation of Myosin Heavy Chain Composition in Human Skeletal Muscle [PDF]

, 2011
Purpose: Information on muscle fiber type composition is of great importance in muscle physiology and athletic performance. Because there are only a few techniques available that noninvasively and accurately provide an estimate of muscle fiber type ...

Muscle growth and flesh quality of farmed Atlantic halibut (Hippoglossus hippoglossus) in relation to season of harvest [PDF]

, 2009
In the present study, muscle growth and flesh quality have been investigated from both commercially farmed Atlantic halibut (Hippoglossus hippoglossus) (Aga marine AS, Norway)and halibut obtained from small-scale trials at Mørkvedbukta Research Station ...

Development of a Non-invasive Methodology for the Assessment of Muscle Fibre Composition

Frontiers in Physiology, 2019
The percentage area of fast twitch fibres of a muscle is a major determinant of muscle mechanical power and, thus, an important biomarker for the evaluation of training processes.

Advances in research on the prenatal development of skeletal muscle in animals in relation to the quality of muscle-based food. I - Regulation of myogenesis and environmental impact [PDF]

, 2010
Skeletal muscle development in vertebrates – also termed myogenesis – is a highly integrated process. Evidence to date indicates that the processes are very similar across mammals, poultry and fish, although the timings of the various steps differ ...

Effects of oxidation in the power of chemically skinned rat soleus fibres [PDF]

, 2010
Oxidation alters calcium sensitivity, and decreases maximum isometric force (Po) and shortening velocity (Vmax) of single muscle fibres. To examine the effect of oxidation on the curvature of the force-velocity relationship, which determines muscle power

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

HISTOCHEMICAL DIFFERENTIATION OF THE PECTORALIS MAJOR MUSCLE FIBRES OF TWO - ALLIED FORMS OF COLUMBA LIVIA [PDF]

Assiut Veterinary Medical Journal, 1975
The pectoralis major muscle of the domestic form of Columba livia revealed the presence of three types of muscle fibres, red, white and intermediate, while that of the wild form was made up of 2 distinct components of fibres, red and white.
