concentration of free calcium
We conclude that vasopressin induces a rapid rise in the cytoplasmic concentration of free calcium ions in corticotrophs.
      
The formation and stabilization of this proteinase was found to be dependent on the concentration of free calcium ions.
      
Therefore the hypothesis has been tested that ELF-EMF-induced DNA strand breaks might be mediated by cellular processes that cause alteration of the intracellular concentration of free calcium ([Ca2+]i) and/or the membrane potential (ΔΨm).
      
An increase in the concentration of free calcium ions during metaphase appears to stimulate the onset of anaphase.
      
Calcium-mediated intracellular signal transduction and the regulation of the concentration of free calcium in B-cells probably involve calcium-binding proteins.
      
At every ionic strength the activity practically disappears when the concentration of free calcium ions ≦10-7 M and reaches a maximum for all ionic strength with a concentration of ~10-5 M.
      
In the resting cells the cytosolic pH was 7.3-7.5 and the concentration of free calcium was 119±24 nM.
      
Using Ca2+-selective microelectrodes, the concentration of free calcium ([Ca2+]) in the cytosol has been measured in root hair cells of Medicago sativa L.
      
The ability of the gliotoxic compounds D,L-, D- or L-2-aminoadipic acid (AAA) to increase selectively the intracellular concentration of free calcium ion ([Ca2+]i) was examined in Müller cells cultured with or without retinal neurons.
      
The cells are equipped with a number of processes for reestablishing the normal very low intracellular concentration of free calcium.
      
The open probability of channels showing stable gating was increased at positive membrane potentials and was sensitive to the concentration of free calcium ions at the cytosolic surface of the patch ([Ca2+]i).
      
In the absence of EDTA, free calcium (approximately 10-6mol/l) stimulates Na,K-ATPase activity; in the presence of EDTA the same concentration of free calcium is without effect on the enzyme.
      
Effects of isoproterenol and suphan on the concentration of free calcium ions in isolated cardiomyocytes: a comparative study
      
The X-ray contrast media omnipaque=melitrast=ultravist >amp;lt;peritrast=hexabrix>amp;lt;triombrast>amp;lt;bilignost decrease the concentration of free calcium ions in blood serum of "sensitive" Wistar ratsin vivo by 15-30%.
      
Increasing the intracellular concentration of free calcium ions by perfusing the cell with solutions containing calcium-EGTA buffer potentiated the TEA-resistant component of the outward current, whereas removal of these ions with EGTA weakened it.
      
The regulation of the intracellular concentration of free calcium probably involves calcium-binding proteins of the calmodulin superfamily.
      
Treatment of particles with EGTA, which chelates selectively Ca2+, leads to unmasking even in the presence of magnesium, indicating that the concentration of free calcium ions plays a major role in the activation process.
      
After influx of calcium from internal stores to the cytoplasm, the concentration of free calcium increases.
      
All these sources of excitation act ultimately by increasing the intracellular concentration of free calcium ions.
      
As mentioned previously, villin's activities with respect to actin change as the concentration of free calcium increases.
