Role of medullary astroglial glutamine synthesis in tooth pulp hypersensitivity associated with frequent masseter muscle contraction

Molecular Pain, 2018
Background The mechanisms underlying tooth pulp hypersensitivity associated with masseter muscle hyperalgesia remain largely underinvestigated. In the present study, we aimed to determine whether masseter muscle contraction induced by daily electrical ...

Impact of contraction intensity and ankle joint angle on calf muscle fascicle length and pennation angle during isometric and dynamic contractions

Scientific Reports
During muscle contraction, not only are the fascicles shortening but also the pennation angle changes, which leads to a faster contraction of the muscle than of its fascicles. This phenomenon is called muscle gearing, and it has a direct influence on the

Essential Role of ATP Synthesized by Creatine Kinase in Contraction of -Toxin Permeabilized Preparations of Tonic Type Smooth Muscle

Journal of Pharmacological Sciences, 2003
The role of ATP newly synthesized from ADP and phosphocreatine (PC) by creatine kinase (CK) in the contraction of tonic type smooth muscle, rat femoral artery was studied, since its necessity for phasic type smooth muscle was previously shown. In α-toxin-

Exaggerated Pressor Response in Relation to Attenuated Muscle Temperature Response during Contraction in Ischemic Heart Failure

Frontiers in Physiology, 2012
It is known that muscle temperature (Tm) increases with exercise. The purpose of this study was to examine if contraction-induced increase in Tm was altered in rats with heart failure (HF) induced by chronic myocardial infraction (MI) as compared with ...

Expertise-Related Differences in Wrist Muscle Co-contraction in Drummers

Frontiers in Psychology, 2020
Background and Aim: Drumming requires excellent motor control and temporal coordination. Deploying specific muscle activation patterns may help achieve these requirements.

Effect of Uni and Bilateral High-Intensity Sustained Isometric Contraction Exercise on Fatigue Related Changes in Quadriceps Femoris

Baltic Journal of Sport and Health Sciences, 2020
Background. It is well established that different types of exercise can provide central and peripheral fatigue. However, there are conflicting findings in the literature, and a consensus has not been reached regarding the different patterns of different ...

Comments on the thermodynamical background to the growth and remodelling theory applied to a model of muscle fibre contraction

Applied and Computational Mechanics, 2010
Muscle fibre contraction is a complex thermomechanical process. The change in muscle fibre length (isotonic contraction) and tension (isometric contraction) may be regarded as muscle fibre growth (change in length) and remodelling (change in stiffness ...

Neural regulation of hindlimb muscle contraction-induced glucagon-like peptide-1 and peptide YY secretion in rats

Journal of Physical Fitness and Sports Medicine, 2015
The physiological mechanisms underlying the increases observed in glucagon-like peptide-1 (GLP-1) and peptide YY (PYY) plasma levels with exercise currently remain unknown.
