Magnetic bimerons are topologically nontrivial spin textures in in-plane easy-axis magnets, which can be used as particle-like information carriers. Here, we report a theoretical study on the nonreciprocal dynamics of asymmetrical ferrimagnetic (FiM) induced by currents. The FiM have ability to move at speed kilometers per second and do not show skyrmion Hall effect angular momentum compensatio...

Whole cell patch-clamp recordings were obtained from supraoptic neurons to investigate the effects of histamine on excitatory postsynaptic currents evoked by electrical stimulation of areas around the posterior supraoptic nucleus. When cells were voltage-clamped at -70 mV, evoked excitatory postsynaptic currents had amplitudes of 88.4 +/- 9.6 pA and durations of 41.1 +/- 3.0 ms (mean +/- SE; n ...

Expression of G protein alpha subunits of the Gq family with various G protein-coupled receptors induces activation of an inositol 1,4, 5-trisphosphate (IP3)/Ca2+-mediated Cl- conductance in Xenopus oocytes. Our present data show that two members of this family, the human Galpha16 subunit and the murine homologue Galpha15, can induce both activation and inhibition of these agonist-induced curre...

Optically induced spin currents have proven to be useful in spintronics applications, allowing for sub-ps all-optical control of magnetization. However, the mechanism responsible their generation is still heavily debated. Here we use excitation spin-current THz spin-waves noncollinear bilayer structures directly study optical spin-currents time domain. We measure a significant laser-fluence dep...

The Slo3 gene encodes a high conductance potassium channel, which is activated by both voltage and intracellular alkalinization. Slo3 is specifically expressed in mammalian sperm cells, where it gives rise to pH-dependent outwardly rectifying K(+) currents. Sperm Slo3 is the main current responsible for the capacitation-induced hyperpolarization, which is required for the ensuing acrosome react...

Results In PC12 cells stably expressing rat P2Y1 receptors (PC12P2Y1), but not in wild type PC12 cells (PC12-wt), ADP induced rises in intracellular Ca2+ with half-maximal effects at 15 ± 1.3 μM. In whole-cell patch-clamp recordings, ADP inhibited ICa of PC12-P2Y1 cells (EC50: 6.3 ± 1.7 μM) and of PC12-wt (EC50: 3.8 ± 1.3 μM); this effect was not altered by the P2Y1 antagonist MRS 2216 (1 μM), ...

In the present study we investigated the modulation of hypothalamic NMDA receptor-mediated currents by cyclic AMP-dependent protein kinase (PKA) using the two-electrode voltage-clamp technique in Xenopus oocytes injected with rat hypothalamic mRNA. Application of forskolin, which activates PKA by means of cyclic AMP stimulation, caused a transient increase of NMDA-induced currents, whereas the ...

The effects of unsaturated fatty acids on membrane properties were studied using conventional whole-cell patch-clamp recording of isolated wing (Ib) cells in bullfrog (Lithobates catesbeianus) taste discs. Applying arachidonic acid to the bath induced monophasic inward currents in 60% of wing cells and biphasic inward and outward currents in the other cells. The intracellular dialysis of arachi...

We demonstrate supersymmetry in the counting statistics of stochastic particle currents and use it to derive exact nonperturbative relations for the statistics of currents induced by arbitrarily fast time-dependent protocols.

Several reports have shown that a sciatic nerve conditioned media (CM) causes neuronal-like differentiation in PC12 cells. This differentiation is featured by neurite outgrowth, which are exclusively dendrites, without axon or sodium current induction. In previous studies, our group reported that the CM supplemented with a generic inhibitor for tyrosine kinase receptors (k252a) enhanced the CM-...
