Lattice Boltzmann method for integrating the Bloch equation in muscle fibers and microvessels
… diffusion and lipid concentration in the human muscle. Strong correlations have also been found between overall fitness and MRI measurements related to the transport of water inside the muscle fibers. In addition to water diffusion within the muscle, MR imaging has been used to obtain …

Excitation-Contraction Coupling: The Effect of Calcium Channel Antagonistic Drugs on Reprimed and Inactivated Skinned Skeletal Muscle Fibers
… of skinned (sarcolemma removed), skeletal muscle fibers can be elicited by sudden changes in the ionic composition of the myoplasm. The bulk of evidence in the literature suggests that such contracture of skinned fibers is triggered by depolarization of resealed transverse tubules. If this …

Voltage-Gated Sodium Channel Activity in Mouse Skeletal Muscle Fibers: Normal Gating and Defects Associated with Periodic Paralysis Mutants
… in SCN4A, the gene encoding the skeletal muscle Na+ channel (NaV1.4) α-subunit, cause several disorders related to skeletal muscle excitability. The functional consequences of these NaV1.4 mutations have been extensively characterized in heterologous expression systems. These studies have …

Green tea extract and epigallocatechin gallate decrease muscle pathology and NF-κB immunostaining in regenerating muscle fibers of mdx mice
… genetic disorder characterized by severe muscle wasting and early death in affected boys. The primary cause of this disease is mutations in the dystrophin gene resulting in the loss of the dystrophin protein from the plasma membrane of muscle fibers. In the absence of dystrophin, muscles …

Facilitation At Neuromuscular Junctions in Crayfish Deep Abdominal Extensor Muscles
… was investigated in the deep extensor muscles of the crayfish. The posterior branches of the motor nerve to these muscles were stimulated while intracellular recordings were made of the electrical responses of the muscle fibers. The excitatory junction potentials (ejp's) of the muscle …

Metabolic profile of myosin heavy chain-based fiber types in the rat soleus after spinal cord transection
Fully differentiated muscle fibers can undergo considerable phenotypic changes in order to adjust to changing conditions of the physiological environment. It is generally accepted that the electrical impulses a muscle receives play a role in modulating the quantities of metabolic proteins …

Changes in Skeletal Muscle Sarcoplasmic Reticulum Function in Adult and Aged Fisher 344 Brown x Norway Rats
… with aging has been linked to reduced skeletal muscle function. It has been theorized that Ca2+ uptake and release by the sarcoplasmic reticulum (SR) is altered with aging. Data pertaining to the actual structural and functional changes of SR due to aging are limited; thus, this theory has not …

Elastografia Supersonic Shear Imaging em músculo esquelético: análise da anisotropia do músculo gastrocnêmio lateral e relação entre a angulação de fibras musculares e sintéticas e o módulo de cisalhamento
… propagation does not occur completely in the fibers direction in pennate muscles, therefore, anisotropy must be considered when obtained shear modulus (μ) by Supersonic Shear Imaging (SSI) elastography. As the pennation angle (PA) varies between muscles, individuals and dynamic conditions, its …

Effects of collagen content, fiber alignment, storage and heating on cooking characteristics, dimensional changes and microstructure of restructured beef
… temperature than aligned steaks. Orientation of fibers had no effect (P>O.l) on cooking losses and physical measurements except Ll and the straight region (L2) on the perimeter of the steak. Broiling yielded higher evaporation and total cooking losses than roasting. Drip losses were not different …

Controlled Myogenic Differentiation of Mammalian Cell Lines by Temperature-Inducible Systems
Efficient in vitro generation of skeletal muscle tissue from cell lines is pivotal for the advancement of cultivated meat production. Here, we introduce a novel system employing a synthetic temperature-sensitive promoter (HSP70) carrying multiple heat shock elements (HSE), whose activity can be …

Physiology and pharmacology of flatworm muscle
… currents carried by VOCCs in isolated S. mansoni muscle fibers, using whole cell configuration of the patch-clamp technique in voltage-clamp mode. Inward voltage-activated current was recorded, under conditions that suppressed outward K+ conductance, by the replacement of internal K+ with Cs+ and …

The effect of smooth muscle antagonists on the sound-induced motion of the tympanic membrane
… several mammalian species contains contractile fibers, which are located primarily within the thickened border of the pars tensa known as the annulus fibrosis. These contractile fibers resemble smooth muscle fibers. Yang and Henson (2002) studied the physiological effects of pharmacological …

Contractile Performance and Energy Utilization of Skeletal Muscle; Creatine Kinase and Acto-myosin ATPase
… ATPase (A‧M‧ATPase) and research in cardiac muscle has found that PCr can alter contractile performance (maximal isometric force and Ca²⁺ sensitivity). Based on this evidence, CK and A‧M‧ATPase may be coupled in skeletal muscle. Therefore the purpose of this investigation was to determine the …
