Three-Dimensional Simulation of Qeshm Channel Currents
Qeshm Channel is a shallow and narrow waterway located between Qeshm Island and the mainland in the vicinity of Hormuzgan Province, Islamic Republic of Iran. This channel is important because of its economic, industrial, fisheries and navigation role it plays as well as environmental issues it presents in the region. A prognostic study was performed to simulate currents in this channel, using C...
متن کاملThe effect of tetramethylammonium on single sodium channel currents.
Voltage-dependent Na conductance of rat myotubes was studied by patch recordings of single-channels. The patches were excised from the cell with the patch electrode, and the cytoplasmic surface was bathed in either CsF or tetramethylammonium (TMA)-F. Inward currents were examined from -20 to -50 mV. In this range Cs and TMA both appeared to be nearly impermeant, but TMA blocked the channel in a...
متن کاملSingle-channel mechanosensitive currents.
Morris and Horn (1) describe ion channel activity, elicited by mechanical stimulation, in both membrane patches and in whole neurons from the snail Lymnaea stagnalis. In whole-cell recordings, mechanical stimulation did not elicit the large macroscopic mechanosensitive currents (IMs) that were anticipated from studies of single mechanosensitive (MS) channels in membrane patches. These negative ...

متن کاملA prokaryotic voltage-gated sodium channel.
The pore-forming subunits of canonical voltage-gated sodium and calcium channels are encoded by four repeated domains of six-transmembrane (6TM) segments. We expressed and characterized a bacterial ion channel (NaChBac) from Bacillus halodurans that is encoded by one 6TM segment. The sequence, especially in the pore region, is similar to that of voltage-gated calcium channels. The expressed cha...
