Effect of Cell Size and Shape on Electric Field Threshold and Critical Transmembrane Voltage for Electroporation
Introduction: Electroporation is a technique for increasing the permeability of the cell membrane to otherwise non-permeate molecules due to an external electric field. This permeability enhancement is detectable if the induced transmembrane voltage becomes greater than a critical value which depends on the pulse strength threshold. In this study, the variabil...
متن کاملVoltage Sensor
The Tokamak Physics Experiment (TPX) was a steady-state, tokamak to be built at the Princeton Plasma Physics Laboratory. It would have been the first tokamak in the world with an entirely superconducting magnet system. The project was terminated by the United States Congress in 1995. However, most of the TPX mission has been adopted recently by the South Korean project KSTAR (Korean Superconduc...
متن کاملA voltage-sensor water pore.
Voltage-sensor (VS) domains cause the pore of voltage-gated ion channels to open and close in response to changes in transmembrane potential. Recent experimental studies suggest that VS domains are independent structural units. This independence is revealed dramatically by a voltage-dependent proton-selective channel (Hv), which has a sequence homologous to the VS domains of voltage-gated potas...
متن کاملA universal CMOS voltage interface circuit
| A CMOS interface circuit to transfer a digital signal between two circuits of di erent supply voltages is described. The interface can be used, for example, between 3 volt and 5 volt or higher voltage families. The principal characteristics of the interface circuit are: no static power dissipation, high speed, and high speed bu ering [1].
متن کاملIntermediate state trapping of a voltage sensor
Voltage sensor domains (VSDs) regulate ion channels and enzymes by undergoing conformational changes depending on membrane electrical signals. The molecular mechanisms underlying the VSD transitions are not fully understood. Here, we show that some mutations of I241 in the S1 segment of the Shaker Kv channel positively shift the voltage dependence of the VSD movement and alter the functional co...
