Sentence examples for membrane potential very from inspiring English sources
Occasionally, and more so at higher membrane potential, very large and sustained openings ('large-open' behaviour, LO) are observed in wild-type PapC usher.
As well as the effects on mitochondrial membrane potential, very low levels of oxygen led to decreased protein expression of superoxide dismutase (SOD) 1 and 2. Superoxide dismutases form part of the cellular antioxidant system, along with nonenzymatic components, such as glutathione and thioredoxin, tasked to maintain cellular redox status.
In our new data, two observations support the view that changes in Nav gating range are not the explanation for the greater excitability of dKO neurons: first, simple inhibition of the ramp-activated outward current in WT cells by the concentration of Cs found to largely block KNa current produces a shift in the 0 current membrane potential very similar to that observed in dKO neurons.
MTG is a dye that is reported to stain mitochondria even when their membrane potential is very low [32].
In a slice preparation, the membrane potential fluctuates very little, presumably leaving all voltage dependent ion channels in a similar state.
Basal cells responded with larger changes in membrane potential, with very little or no hyperpolarization from rest and depolarizing up to –13.9 ± 1.6 mV, which corresponds to the peak of the calcium current (Johnson and Marcotti, 2008).
In this mock example the moving average of the membrane potential seems to provide very similar information as the spike density function.
Because the dominant Kir conductance determines the very negative membrane potential of Müller cells, the small current amplitudes are accompanied by less negative membrane potentials.
As the model was used for simulations within a very narrow membrane potential range, it was simplified to not include any active membrane conductances.
The dominant K+ conductance of glial cells mediates spatial K+ buffering and is important for the very negative membrane potential of these cells, thereby supporting electrogenic membrane transporters.
Mitochondria can continuously oxidize substrates and maintain a proton gradient across the lipid bilayer with a very large membrane potential (−180 mV).
