In Wikipedia:

Thus, when these protons flow back in, they are used in the synthesis of ATP (this proton flow can be emulated with an increase in pH outside of the cell, causing a flow of H + ions).

In Wikipedia:

The flow of ions that causes an EPSP is an excitatory postsynaptic current’ “(EPSC).
(Parse)

In Wikipedia:

When tension increases, the flow of ions across the membrane into the hair cell rises as well.

In the ICWSM 2009 Weblog Corpus:

Today my professor was giving a lecture on voltage – gated channels in neurons and mentioned there was a brief ‘inactive’ state that was neither open nor closed, just ‘capped’ to prevent flow of ions.
(Parse)

In Wikipedia:

At this point, the net flow of this specific ion (in this case sodium) is zero.
(Parse)

In Wikipedia:

In this case, the voltage refers to the voltage across a biological membrane, a membrane potential, and the current is the flow of charged ions across channels in this membrane.
(Parse)

In Wikipedia:

Neurotransmitters are ligands that are capable of binding to ion channel proteins, resulting in their opening to allow the rapid flow of a particular ion across the plasma membrane.
(Parse)

In Wikipedia:

In the outer region, only a flow of negative ions and, to a lesser and radially – decreasing extent, free electrons toward the positive electrode takes place.
(Parse)

In Simple Wikipedia:

Ion channels are pore-forming proteins that help to establish and control the small voltage gradient across the plasma membrane of all living cells (see resting potential) by allowing the flow of ions down their electrochemical gradient.
(Parse)

In Wikipedia:

The flow of ions through the channel itself modulates neuron polarization and thus affects neuron excitability.
(Parse)

In Wikipedia:

A mutation in the ANK2 gene likely alters the flow of ions between cells in the heart, which disrupts the heart’s normal rhythm and results in the features of Romano – Ward syndrome.

In the ICWSM 2009 Weblog Corpus:

in cardiac physiology is related to the ion currents which in cardiac cells as in nerve cells flow into and out of the cell The flow of ions translates into a change in the voltage of the inside of the cell relative to the extracellular space As in nerve cells this characteristic change in voltage is referred to as an action potential Unlike nerve cells the cardiac action potential duration is closer to 100 ms (with variations depending on cell type autonomic tone etc) After an actio’s team sheet for more than 15 years thereafter unless injured or suspended Bremner quickly established himself as an uncompromising player tough in the tackle and often going beyond the rules to get the better of a skilled opponent – a Sunday Times headline dubbed him as 10st of barbed wire Jacqueline Bouvier and then Congressman John Kennedy were in the same social circle and attended the same functions several times but were formally introduced by a mutual friend journalist (shrimp) is common as are barbecued cuts of steak or chicken breasts drumsticks and wings Australia also has a sweet called White Christmas Fruits of the season include

In Wikipedia:

Muscle contraction and relaxation are controlled by the flow of ions into and out of muscle cells.
(Parse)

In the ICWSM 2009 Weblog Corpus:

Mice were subjected to stress – inducing conditions after being injected with an isolated incense compound, and it was found to soothe them in a manner similar to antidepressant and antianxiety drugs: Further investigation revealed that the compound, named incensole acetate, can regulate the flow of ions in and out of neurons in a manner similar to the way antidepressant drugs work.
(Parse)

In Wikipedia:

Within a few milliseconds, the retinal relaxes back to the all – trans form, closing the pore and stopping the flow of ions.
(Parse)

In Wikipedia:

Since one of the assumptions of the GHK flux equation is that the ions move independently of each other, the total flow of ions across the membrane is simply equal to the sum of two oppositely directed fluxes.
(Parse)

In Wikipedia:

In neuroscience, an excitatory postsynaptic potential’ “(“’EPSP ’”) is a temporary depolarization of postsynaptic membrane potential caused by the flow of positively charged ions into the postsynaptic cell as a result of opening of ligand – sensitive channels.
(Parse)

In Wikipedia:

At membrane potentials negative to the channel’s resting potential, inwardly rectifying K + channels support the flow of positively charged K + ions into the cell, pushing the membrane potential back to the resting potential.
(Parse)

In Wikipedia:

The free flow of ions between cells enables rapid non – chemical mediated transmission.
