Sphingomyelinase decreases transepithelial anion secretion in airway epithelial cells in part by inhibiting CFTR‐mediated apical conductance

open access: yesPhysiological Reports, 2021
The cystic fibrosis transmembrane conductance regulator (CFTR) is an anion channel whose dysfunction causes cystic fibrosis (CF). The loss of CFTR function in pulmonary epithelial cells causes surface dehydration, mucus build‐up, inflammation, and ...

Stomatal Responses to Light, CO2, and Mesophyll Tissue in Vicia faba and Kalanchoë fedtschenkoi

open access: yesFrontiers in Plant Science, 2021
The responses of stomatal aperture to light intensity and CO2 concentration were studied in both Vicia faba (C3) and Kalanchoë fedtschenkoi (Crassulacean acid metabolism; CAM), in material sampled from both light and dark periods.

Admittance of Atomic and Molecular Junctions and Their Signal Transmission

open access: yesMicromachines, 2018
Atom-sized contacts of metals are usually characterized by their direct current (DC) conductance. However, when atom-sized contacts are used as device interconnects and transmit high frequency signals or fast pulses, the most critical parameter is not ...

COMPASS: A New COnductance Model Based on PFISR And SWARM Satellite Observations

open access: yesSpace Weather, 2022
Ionospheric conductance plays a crucial and active role in magnetosphere‐ionosphere‐thermosphere coupling processes. Despite its importance, direct global observations of conductance are unavailable.

Electrical Parameters as Diagnostics of Fresh Engine Oil Condition—Correlation with Test Voltage Frequency

open access: yesSensors, 2023
The aim of this study was to assess whether electrical parameters (capacitance and conductivity) of fresh engine oils—tested over a wide range of measurement voltage frequencies—can be used for oil quality assessment and its identification, based on ...

Theoretical study on quantum transport of carbon nanotubes for detecting toxic molecules: The role of dopants

open access: yesJournal of Electrochemical Science and Engineering, 2022
We study the effects of dopant atoms on quantum transport and adsorption properties of environmentally harmful (CO2), toxic (CO) and common (O2 and N2) molecules of carbon nanotubes (CNTs) based on the first-principles electronic structure and quantum ...

Inhibitory noise

open access: yesFrontiers in Cellular Neuroscience, 2010
Cortical neurons in vivo may operate in high-conductance states, in which the major part of the neuron's input conductance is due to synaptic activity, sometimes several-fold larger than the resting conductance.

Influence of Delayed Conductance on Neuronal Synchronization

open access: yesFrontiers in Physiology, 2020
In the brain, the excitation-inhibition balance prevents abnormal synchronous behavior. However, known synaptic conductance intensity can be insufficient to account for the undesired synchronization. Due to this fact, we consider time delay in excitatory

How to properly measure a current-voltage relation? - Interpolation versus ramp methods applied to studies of GABAA receptors

open access: yesFrontiers in Cellular Neuroscience, 2016
The relation between current and voltage, I-V relation, is central to functional analysis of membrane ion channels. A commonly used method, since the introduction of the voltage-clamp technique, to establish the I-V relation depends on the interpolation ...
