Sentence examples for membrane potential shift from inspiring English sources

The potentiometric response of copper hexacyanoferrate membranes electrodeposited above 0.40 V vs SCE became however weaker with decreasing K+ content in CuHCF membranes and both the amount of preferential K+ dissolution and the extent of the membrane potential shift became smaller during the membrane conditioning.

We introduced the corresponding term into our model for the Ca2+ ions movement via the membrane as a function of the corresponding membrane potential shift (equation 43).

Mitochondrial membrane potential (MMP) was measured with Mitochondrial Membrane Potential Detection Kit (Stratagene) according to the manufacturer's protocol using JC-1 dye, and mitochondrial membrane potential shift was measured using FACS Calibur flow cytometer using CellQuest acquisition software (BD Biosciences).

Their more hyperpolarized Vm (about –65 mV), due to the much smaller resting MT current, and consequently greater membrane time constant, means that the responses of basal cells to even low level sounds summate into a DC membrane potential shift that is proportional to stimulus intensity.

When this K2Cu3[Fe(II)(CN 6]2 membrane was immersed and conditioned in 0.1 M (CH3 4N·NO3 (tetramethylammonium nitrate, TMA·NO3) solution prior to potentiometric measurements, the preferential dissolutions of K+ ions into the adjacent solution was observed accompanying negative membrane potential shifts (more than 200 mV).

Steady membrane potential shifts modify [Cl−]i, while the concentrations of the other major ions, Na+ and K+, are presumably hardly affected.

A comparison of the membrane potential shift-induced intraciliary Ca2+ spike generation in the presence of the K+ currents with the model when K+ channels are not incorporated, suggests that while the K+ currents change the quantitative values of the Ca2+ concentration dynamics, the general shape of the Ca2+ response remains the same.

The predictions for the individual Ca2+ and K+ current responses to various membrane potential shifts are shown in Figure 10.

Equations (20) and (21) in the Methods section were used for quantitative estimations of the Ca2+ concentration and current responses to the normalised membrane potential shifts.

In contrast, the distribution of membrane potential shifted from red (FL-2) to green (FL-1) fluorescence when carbonyl cyanide m-chlorophenylhydrazone (CCCP), a protonophore, was treated as a positive control, through its effects on mitochondrial uncoupling.

β-toxins bind to a separate site, independently of membrane potential, and shift the channel activation to the hyperpolarizing direction [ 7, 8].
