Here, θ H c is defined as the threshold of channel c and calculated based on the average energy of channel c as follows: θ H c = 1 M · α ∑ m = 1 M A ( c, m, 0 ) (5).
We find that a combination of higher temperature and pH are required to reduce the activation threshold of channel opening in Bacillus Nav channels, which is unique to this family of sodium channels.
The authors also characterized the voltage-, pH- and temperature-dependence of several Nav channels from several Bacillus species and demonstrated that a combination of higher temperature and pH are required to reduce the activation threshold of channel opening in these alkaliphilic Bacillus bacteria.
Costes' algorithm firstly calculates a least-squares fit for the 2D scattergram based on orthogonal regression and then progressively lowers intensity thresholds for both axes of the scatterplot and calculates the r between the pixels beneath the intensity thresholds of each channel until it reaches a pair of thresholds beneath which r is no longer positive.
Perhaps the rise in [Ca2+]i during priming activates Ca2+-dependent enzymes (28), which alter the activity of Kv7 channels, the activation threshold of Ca2+ channels, or the Ca2+ sensitivity of contraction.
Expression of Kv7 channels in oocytes leads to a hyperpolarization of the oocytes to membrane potentials that lie close to the activation threshold of the channels.
We used the Colocalization plugin (Pierre Bourdoncle, 2003), which considers that two signals colocalize if their respective intensities are strictly higher than the threshold of their channels and if their ratio of intensity is strictly higher than the ratio setting value (here, 75%).
We propose that bidirectional regulation of HCN channel activation by cyclic nucleotides plays an important role in regulating the set point and threshold of HCN channel activation in neurons.
As these particles are generally smaller than a few tens of nanometers, it is clear that forces acting on such particles will also fall well below the threshold of ion channel activation.
In order to assure the QoS for the licensed users, the WSP determine a threshold on the number of channels allowed to licensed users and reserves the rest of bandwidth to unlicensed users.
