A cultured C2C12 myotube contraction system was examined for application as a model for acute contraction-induced phenotypes of skeletal muscle. C2C12 myotubes seeded into 4-well rectangular plates were placed in a contraction system equipped with a carbon electrode at each end. The myotubes were stimulated with electric pulses of 50 V at 1 Hz for 3 ms at 997-ms intervals. Approximately 80% of ...
In this article, we study the existence of mild solutions for nonlocal Cauchy problem for fractional neutral evolution equations with infinite delay. The results are obtained by using the Banach contraction principle. Finally, an application is given to illustrate the theory. Full text
For linear evolution families in Banach spaces, we establish the robustness of a weaker notion of exponential dichotomy. This notion allows the contraction and expansion along the stable and unstable subspaces to be nonuniform and requires nothing from the angles between these subspaces.
conclusions the application of 5-ht1a, 5-ht2, 5-ht3, 5-ht4, 5-ht6 and 5-ht7 receptor antagonists, applied at concentrations lower than 1.0 µm did not modify the efs-induced contraction and relaxation responses, whichsuggests the unlikely involvement of endogenous 5-ht in mediating responses to efs in the described test conditions. materials and methods segments taken from the rat duodenum, jeju...
background and aims: the antioxidant and anti-inflammatory effects of carvacrol were reported. the aim of the current study was an investigation the relaxant effects of carvacrol on acetylcholine-induced contraction in isolated rat's ileum. materials and methods: in this study, the tissues separated from ileum were fixed on the organ bath containing tyrode's solution. the amplitude of...
Advances in sequencing and generating high-throughput expression data have created a situation in which it is possible to integrate comparative analysis with genome-wide studies of the structure and function of regulatory systems in model organisms. Recent studies have focused on topological properties and the evolution of regulatory networks. This problem can be addressed on several levels: ev...
A new derivation of the quantum Boltzmann transport equation for the Fermion system from the quantum time evolution equation for the wigner distribution function is presented. The method exhibits the origin of the time - irreversibility of the Boltzmann equation. In the present work, the spin dependent and indistinguishibility of particles are also considered.
study on this order which was issued for establishing government macro-organization in 1866, clarifies the king’s purpose to create a new administrative system in the country. analysing different views in this respect, the paper discusses method of dividing the ministers’ duties, their power and authorization, shah’s expectations of them:, and the relations between shah and his ministers. the a...
With the development of social economy, current changes in flow people three eastern provinces and cities show trend GDP reduction population loss, which can be called urban contraction. Based on 30 Liaoning Province, this paper discriminates types development, further classifies shrinking cities, explores factors that affect their degree, summarizes different puts forward corresponding improve...
Mechanisms linked to actin filaments have long been thought to cooperate in smooth muscle contraction, although key molecules were unclear. We show evidence that cardiac troponin T (cTnT) substantially contributes to Ca(2+)-mediated contraction in a physiological range of cytosolic Ca(2+) concentration ([Ca(2+)](i)). cTnT was detected in various smooth muscles of the aorta, trachea, gut and uri...
