Sentences with phrase «intracellular calcium concentrations»

Thanks to research over the past 15 years or so, we now know that the bitter taste receptors in our mouths release neurotransmitters that stimulate, via the vagus nerve, an increase in intracellular calcium concentrations.

We observed similar robust increases of intracellular calcium concentrations in response to KCl and ATP in both GFP - expressing (n = 28) and GFP - nonexpressing cells (n = 12), whereas 5 - HT elicited an increase in intracellular calcium only in GFP - expressing cells (KCl: t (40) = 0.98, p = 0.33; ATP t (38) = 1.04, p = 0.30; 5 - HT: t (38) = 5.24, p < 0.0001 Student's t tests; Fig. 4A, B, F).

Measurement with the fluorescent calcium indicator fura - 2 indicated that the IgG treatment reduced potassium - stimulated increase in free intracellular calcium concentration.

In one series, excised rat heart muscle tissue was mounted onto a device that directly measured the force of contraction at the same time as intracellular calcium concentration.

Simultaneous exposure to ATP and phenylephrine induces a sustained elevation in the intracellular calcium concentration in supraoptic neurons.

The exact mechanism how dopamine enhances hGH is still being researched, however experts believe that it does so by increasing another hormone called GHRH which acts by increasing intracellular calcium concentration in pituitary cells which secrete growth hormone.
