Sentence examples for membrane potential hyperpolarization from inspiring English sources

Following photo-excitation and subsequent decrease in cellular cGMP, these channels close and raise the cell membrane potential (hyperpolarization), producing an electrical current (Yau and Baylor 1989).

Treatment for 30-60 min with progesterone or the progestin, R5020, increased mitochondrial activity as shown by an increase in mitochondrial membrane potential (hyperpolarization) with a concordant increase in total cellular ATP.

This is likely to influence the redistribution of the ions on either side of the membrane, leading to change in the concentration gradients of these ions and the membrane potential (hyperpolarization).

The results demonstrated the occurrence, sometimes in the same neurons, of both reduced synaptic RF amplitude, and of global membrane potential hyperpolarization.

The fluorescence profile during OS differentiation showed decreased membrane potential (hyperpolarization) compared to undifferentiated cells after 2, 3, and 4 weeks of differentiation, with the 4-week-differentiated samples being the most hyperpolarized (Fig. 1).

This long-lasting hyperpolarization has been shown to depend, at least partially, on intrinsic membrane properties, as high-intensity current injection in single neurons in vivo results in a membrane potential hyperpolarization that mimics the one obtained with high contrast visual stimuli, and which is able to reduce responses to visual stimuli [35], [73].

Fluorescence readings of differentiating cells decreased in intensity as a function of differentiation time, which corresponds to more negative membrane potential, or hyperpolarization.

Mitochondrial ROS production is linked to the rate of respiration and therefore also to the mitochondrial membrane potential, with hyperpolarization contributing to higher rates of respiration and thus increased electron leak/ROS production.

It also reduced the membrane potential, leading to hyperpolarization and thus influencing activation and inactivation of the ion channels.

In particular, the mitochondrial membrane potential (MMP) increase (hyperpolarization) and the MMP loss (depolarization) were analyzed at different times after the end of UVB exposure.

Subsequent studies, using valinomycin to manipulate membrane potential, indicated that hyperpolarization increased the susceptibility to blockade by ryanodine of the Ca2+ release evoked by Ni2+(182).
