Oxidation-reduction and photophysical properties of isomeric forms of Safranin.

open access: yesPLoS ONE, 2022
Safranine O is widely used in the bioenergetics community as an indicator dye to determine membrane potentials and as an electron transfer mediator in potentiometric titrations.

Synapses with short-term plasticity are optimal estimators of presynaptic membrane potentials

open access: yesNature Neuroscience, 2010
The trajectory of the somatic membrane potential of a cortical neuron exactly reflects the computations performed on its afferent inputs. However, the spikes of such a neuron are a very low-dimensional and discrete projection of this continually evolving

Information encoding and reconstruction from the phase of action potentials

open access: yesFrontiers in Systems Neuroscience, 2009
Fundamental questions in neural coding are how neurons encode, transfer, and reconstruct information from the pattern of action potentials exchanged between different brain structures.

Depolarization of the conductance-voltage relationship in the NaV1.5 mutant, E1784K, is due to altered fast inactivation.

open access: yesPLoS ONE, 2017
E1784K is the most common mixed long QT syndrome/Brugada syndrome mutant in the cardiac voltage-gated sodium channel NaV1.5. E1784K shifts the midpoint of the channel conductance-voltage relationship to more depolarized membrane potentials and ...

Analogue modulation of back-propagating action potentials enables dendritic hybrid signalling

open access: yesNature Communications, 2016
‘Analogue’ modulation by somatic membrane potentials can modify ‘digital’ axonal action potentials. Here, the authors show that analogue modulation can occur in back-propagating dendritic action potentials and calcium signals, leading to signal ...

Descending Vasa Recta Endothelial Membrane Potential Response Requires Pericyte Communication. [PDF]

open access: yesPLoS ONE, 2016
Using dual-cell electrophysiological recording, we examined the routes for equilibration of membrane potential between the pericytes and endothelia that comprise the descending vasa recta (DVR) wall.

MEMBRANE POTENTIALS AND CATAPHORETIC POTENTIALS OF PROTEINS [PDF]

open access: yesJournal of General Physiology, 1923
1. It has been shown in preceding publications that the membrane potentials of protein solutions or gels are determined by differences in the concentration of a common ion (e.g. hydrogen ion) inside a protein solution or protein gel and an outside aqueous solution free from protein, and that the membrane potentials can be calculated with a good degree ...

Membrane Activity of Melittin and Magainin-I at Low Peptide-to-Lipid Ratio: Different Types of Pores and Translocation Mechanisms

open access: yesBiomolecules
Antimicrobial peptides (AMPs) are believed to be a prominent alternative to the common antibiotics. However, despite decades of research, there are still no good clinical examples of peptide-based antimicrobial drugs for system application.

Involvement of MAPKs and PLC Pathways in Modulation of Pacemaking Activity by So-Cheong-Ryong-Tang in Interstitial Cells of Cajal from Murine Small Intestine

open access: yesThe Scientific World Journal, 2013
Purpose. Interstitial cells of Cajal (ICCs) are the pacemaker cells that generate slow waves in the gastrointestinal (GI) tract. We have aimed to investigate the effects of Socheongryong-Tang (SCRT) in ICCs from mouse’s small intestine. Methods.
