Cooperative gating of localized ion channels ranges from fine-tuning excitation–contraction coupling in muscle cells to controlling pace-making activity the heart. Membrane deformation resulting contraction activates stretch-activated (SA) cation channels. The subsequent Ca 2+ influx spatially -sensitive K + fine-tune spontaneous contraction. To characterize endogenously expressed intermediate ...

conclusions results showed that the boiled anethum graveolens seeds was effective on labor induction. results case group had a significantly better bishop score following the intervention compared to the control group. the mean duration of active phase, second and third stages of labor were significantly lower in the case group. the control group had shorter latent phase than the case group. pa...

linear and cord-like burn scar contractures are commonly treated by severing the scar in a transverse direction and skin grafting or performing z-plasties. however, skin grafts may result in suboptimal take and contract gradually and the z-plasty requires undermining flaps in scarred skin which may lead to the distal tip necrosis. in this article the authors present their experience with multip...

recently, rahimi et al. [comp. appl. math. 2013, in press] de ned the conceptof quadrupled xed point in k-metric spaces and proved several quadrupled xed pointtheorems for solid cones on k-metric spaces. in this paper some quadrupled xed point resultsfor t-contraction on k-metric spaces without normality condition are proved. obtainedresults extend and generalize well-known comparable result...

Cyclic contraction and relaxation of plasmodial strands of Physarum polycephalum were measured under both isotonic and isometric conditions, and their relation to changes in microfilament (MF) morphology was investigated. The contraction-relaxation rhythm of a strand segment was insignificant and irregular immediately after isolation from the mother plasmodium. It became regular half an hour la...

Aerodynamically economical flight is steady and level. The high-amplitude flapping and bounding flight style of many small birds departs considerably from any aerodynamic or purely mechanical optimum. Further, many large birds adopt a flap-glide flight style in cruising flight which is not consistent with purely aerodynamic economy. Here, an account is made for such strategies by noting a well-...

MOHRMAN, DAVID E., AND HARVEY V. SPARKS. Myogenic hyperemia following brief tetanus of canine skeletal muscle. Am. J. Physiol. 227(3) : 531-535. We have tested the hypothesis that a portion of the vasodilatory response to brief (1 s) tetanus could be initiated by the rapid alterations in extravascular pressure and in vascular transmural pressure associated with muscle contraction. Dogs were ane...

In the present paper, we show that $S^*$ iteration method can be used to approximate fixed point of almost contraction mappings. Furthermore, we prove that this iteration method is equivalent to CR iteration method  and it produces a slow convergence rate compared to the CR iteration method for the class of almost contraction mappings. We also present table and graphic to support this result. F...

This research was conducted to find a reliable technique to shape an abrupt contraction for minimizing the energy loss. The method may find broader applications in design of variety of transitional cross-sections in hydraulic structures. The streamlines in a 2-D contraction were calculated through solving the potential flow equations in rectangular and curvilinear coordinates. The natural cubic...

Background: Uterine bleeding is an important side effect of cesarean section which is due to non contractile uterine. The aim of this study was to compare the effect of 10% dextrose (IV infusion) and 40 IU/L oxytocin (IV infusion) on uterine contraction. Materials and Methods: This research was a double-blinded randomized clinical trial (RCT) study. 120 women were equally included in the tw...
