Relevance of Viroporin Ion Channel Activity on Viral Replication and Pathogenesis
(MDPI, 2015-07)
Modification of host-cell ionic content is a significant issue for viruses, as several viral proteins displaying ion channel activity, named viroporins, have been identified. Viroporins interact with different cellular ...
Divalent Metal Ion Transport across Large Biological Ion Channels and Their Effect on Conductance and Selectivity
(Hindawi Publishing Corporation, 2012-07)
Electrophysiological characterization of large protein channels, usually displaying multi-ionic transport and weak ion selectivity, is commonly performed at physiological conditions (moderate gradients of KCl solutions at ...
Observation of Long-Term Stable Response in MAPbBr3 Single Crystals Monitored through Displacement Currents under Varying Illumination
(Wiley-VCH GmbH, 2022-06-30)
Long life of perovskite devices in working conditions remains the bottleneck for
technology application. Stable charge carriers’ transport together with nonreactive
contact materials contributes to the increase of the ...
Effect of nanostructured electrode architecture and semiconductor deposition strategy on the photovoltaic performance of quantum dot sensitized solar cells
(Elsevier, 2012)
Here we analyze the effect of two relevant aspects related to cell preparation on quantum dot sensitized solar cells (QDSCs) performance: the architecture of the TiO2 nanostructured electrode and the growth method of quantum ...
Transport mechanisms of SARS-CoV-E viroporin in calcium solutions: Lipid-dependent Anomalous Mole Fraction Effect and regulation of pore conductance
(Elsevier, 2021-06-01)
The envelope protein E of the SARS-CoV coronavirus is an archetype of viroporin. It is a small hydrophobic protein displaying ion channel activity that has proven highly relevant in virus-host interaction and virulence. ...
Probing Tubulin-Blocked State of VDAC by Varying Membrane Surface Charge
(Biophysical Society, 2012-05)
Abiotic depletion and the potential risk to the supply of cesium
(Elsevier, 2020-10)
The petroleum exploration industry is the largest end user of cesium where it is employed in oil well drilling fluid. It has recently been broadly reported that the inclusion of cesium into perovskite for photovoltaics and ...
Coronavirus E protein forms ion channels with functionally and structurally-involved membrane lipids
(Elsevier, 2012-10)
Coronavirus (CoV) envelope (E) protein ion channel activity was determined in channels formed in planar lipid bilayers by peptides representing either the transmembrane domain of severe acute respiratory syndrome CoV ...
PEG Equilibrium Partitioning in the α-Hemolysin Channel: Neutral Polymer Interaction with Channel Charges
(American Chemical Society, 2021-02-08)
We study the interaction of neutral polyethylene glycol (PEG) molecules of different molecular weights (MWs) with the charged residues of the α-hemolysin channel secreted by Staphylococcus aureus. Previously reported ...
Increased salt concentration promotes competitive block of OmpF channel by protons
(Elsevier, 2012-11)
Porins are channel-forming proteins that are located in the outer membranes (OM) of Gram-negative bacteria
and allow the influx of hydrophilic nutrients and the extrusion of waste products. The fine regulation of the
ion ...
