introduction: pentylenetetrazol (ptz) is one of the most often used epileptogenic agents. several effects of this epileptogenic drug have been described, but the mechanism of the epileptogenic action of ptz at the cellular level is still unclear. in this study the effect of ptz, on the ionic currents of d5 neuronal soma membrane in helixaspersa, using intracellular recording technique was inves...

The depth average module of NASIR finite volume solver was applied to study the tide induced currents in Khowr-e-Musa estuary. The model computes water level variation and velocity components in horizontal plane solving depth average continuity and momentum equations considering the hydrostatic pressure distribution. The software takes into account the bed and wall geometric complexities and re...

BACKGROUND Glia-neuron interactions play an important role in the development of neuropathic pain. Expression of the pro-inflammatory cytokne →cytokine Interferon-gamma (IFNγ) is upregulated in the dorsal horn after peripheral nerve injury, and intrathecal IFNγ administration induces mechanical allodynia in rats. A growing body of evidence suggests that IFNγ might be involved in the mechanisms ...

ATP modulates various functions in the dental pulp cells, such as intercellular communication and neurotransmission between odontoblasts and neurons, proliferation of dental pulp cells, and odontoblast differentiation. However, functional expression patterns and their biophysical properties of ionotropic ATP (P2X) receptors (P2X1-P2X7) in odontoblasts were still unclear. We examined these prope...

Abstract The time-varying magnetic field of a storm induces an electric in the earth, which generates geomagnetically induced currents (GIC) when it acts on power grid and has many hazards to system. In this paper, we model calculate ground-induced for 20 storms from 2008 2018, investigate effects two factors, strength, earth conductivity, currents, are important prevention control GIC large-sc...
