Thus, the purpose of this study was to examine the acute effects of short-term (i.e., [less than or equal to]5 min) local vibration to the Achilles tendon on subsequent peak plantar flexor torque during isometric MVCs, twitch contractile properties (e.g., peak twitch torque), plantar flexor muscle activity, and brain activity in young female athletes.
The shape changes necessary for cell migration depends on dynamic organisation and force generation from the cells internal actomyosin cytoskeleton, which is made up of structural actin filaments and contractile myosin motor proteins.
Aging-related changes of intracxellular Ca stores and contractile response of intestinal smooth muscle.
It is likely that signaling proteins might be part of a pathway that induces the actin-poor region and then organizes the thick contractile rings during meiosis in molluscan eggs.
To measure the spontaneous phasic contractile activity, and the contractile responses to cholinergic neurotransmission, muscle strips were incubated with 100 [micro]M L-NAME and 1 [micro]M MRS2500 (to inhibit nitrergic and purinergic inhibitory motor neurons) prior to the delivery of square-wave pulses of electrical field stimulation (EFS) (0.3 ms duration), 150 V and 30 sec duration (supramaximal voltage; Grass S48 stimulator) [16].
Till date, there are only a few studies that demonstrate the contractile mechanisms of human gut musculature of pediatric age group.
Taken together, these findings suggest that the improvements observed in the heart's contractile performance after injury may be the result of an overall reduced fibrotic burden.
Table-III: Comparison of contractile properties of isolated EDL (fast) muscles of diabetic and control groups.
The potassium-induced contraction was used as a reference for the contractile capacity, and the segments were used only if potassium elicited reproducible responses over 1.0 mN.
While the nonselective blockade of NOS did not modify contraction in response to Phe in SMA from both groups of rats (Figures 2(a), 2(b), and 2(c)), it potentiated to the same extent the contractile response to Phe in aortas from both ZF and Provinols-treated ZF rats (Figures 2(d), 2(e), and 2(f)).
Based on these findings, we hypothesized that neurocompensatory response to balloon injury enhances endothelinergic functionality in contralateral carotid, leading to local contractile hyperreactivity to ET-1 by a ROS-dependent mechanism involving [Ca.sup.2+] mobilization upregulation.
Results: All drug treatments significantly reduced carbachol-stimulated tonic contractile activities, but did not change the phasic amplitude.
