First Microscopic Video Blood Clot Contraction Platelets Naturally Unobtrusive Clots
2017/11/24
The first view of the physical mechanism of how a blood clot contracts at the level of individual platelets is giving researchers from the Perelman School of Medicine at the University of Pennsylvania...
2017肌肉戈登学术会议（The 2017 Gordon Research Conference on Muscle: Excitation-Contraction Coupling）
Muscle Excitation-Contraction Coupling
2017/1/18
The first objective of the meeting is to discuss and critically evaluate new breakthroughs regarding the molecular mechanisms that control excitation-contraction coupling (ECC), how this process is al...
Deloading Tape Reduces Muscle Stress at Rest and during Contraction
SUPERSONIC,SHEAR,IMAGING TAPING STRESS PASSIVE,FORCE FORCE,TRANSMISSION
2017/5/25
Taping techniques that aim to protect and reduce stress on an injured tissue during rehabilitation are common in sport. Called deloading tape, the mechanism of action is hypothesized to involve effect...
Central and Peripheral Fatigability in Boys and Men during Maximal Contraction
MUSCLE,FATIGUE MUSCLE,ACTIVATION CHILDHOOD TWITCH,INTERPOLATION EMG M-WAVE
2017/5/23
The purpose of this study was to examine central and peripheral factors of fatigability that could explain the differences in fatigability between adults and prepubertal boys after maximal sustained i...
Contraction Gap versus Shear Bond Strength of Dentin Adhesive in Sound and Sclerotic Dentins
Contraction gap Shear bond strength Sclerotic dentin
2009/9/14
To evaluate the effect of a dentin adhesive on sclerotic dentin, contraction gap width and shear bond strength were measured. Dentin cavity wall was pretreated with an experimental dentin bonding syst...
Hyperbaric exposures alter cardiac excitation-contraction coupling
Cardiac excitation-contraction electrocardiographic heliox hyperbaric
2009/7/16
Cardiac excitation-contraction (E-C) coupling variables were measured in anesthetized cats during helium-oxygen dives to 1000 fsw (305 msw). At constant pacing rates of 190-300/min the delay between o...
Effects of stretching stress on the muscle contraction proteins of skeletal muscle myoblasts
stretching stress muscle contraction proteins skeletal muscle myoblasts
2009/3/2
Several studies have reported that growth and differentiation of cultured myoblasts can be facilitated by applying appropriate mechanical stimulus. However, the effects of mechanical stimulus on the c...
Comparative studies on rabbit corpus cavernosal contraction and relaxation. An in vitro study
Erection corpus cavernosa autonomic agents endothelin endothelium-derived relaxant factor nitric oxide
2009/2/12
Erectile function (erection and detumescence) involves the complex interaction of direct neuronal stimulation of corporal smooth muscle, neurohumoral release of specific endothelial contractile an...
Cavernosus Muscle Contraction During Erection：Is It Voluntary or Reflex, Given the Striated Nature of the Muscles?
Ischio-/bulbo-cavernosus muscle corpora cavernosa intracorporal pressure electromyography
2008/12/24
The bulbo- and ischio-cavernosus muscles (BCM, ICM) contract in the rigid erection phase, leading to a suprasystolic cavernosal pressure. We investigated the hypothesis that the contraction of caver...
Doxazosin and Serotonin（5-HT）Receptor（1A, 2A, and 4）Antagonists Inhibit 5-HT-Mediated Human Cavernosal Contraction
5-hydroxytryptamine erectile dysfunction corpus cavernosum cavernosal tone
2008/12/24
Penile erection results from the balance between relaxation and contractile mechanisms of the corpus cavernosum. Only a few studies suggest a role for endogenous contractile agents such as 5-hydroxy...
Effect of External Anal Sphincter Contraction on the Ischiocavernosus Muscle and Its Suggested Role in the Sexual Act
Electromyography erection impotence corpora cavernosa action potentials erectile dysfunction
2008/12/23
Whereas the bulbocavernosus muscle shares its contractile activity with the external anal sphincter (EAS), the response of the ischiocavernosus muscle (ICM) to EAS contraction could not be traced ...
Inhibition of Tonic Contraction—A Novel Way to Approach Erectile Dysfunction?
Inhibition Tonic Contraction Erectile Dysfunction
2008/12/15
Experiments from this laboratory have demonstrated that vasoconstriction in the cavernosal circulation is mediated, in part, by the RhoA/Rho-kinase calcium-sensitization pathway. When RhoA/Rho-kinase ...
