Electrical Properties of Model Lipid Membranes

open access: yesMembranes, 2022
Biological membranes are essential components of the living systems, and processes occurring with their participation are related mainly to electric phenomena such as signal transduction, existence of membrane potentials, and transport through the ...

An Evaluation of the Accuracy of Classical Models for Computing the Membrane Potential and Extracellular Potential for Neurons

open access: yesFrontiers in Computational Neuroscience, 2017
Two mathematical models are part of the foundation of Computational neurophysiology; (a) the Cable equation is used to compute the membrane potential of neurons, and, (b) volume-conductor theory describes the extracellular potential around neurons.

Effect of methyl β cyclodextrin on freezability and in vitro fertilizing potential of buffalo spermatozoa Badr, M. R. and Mary G. Abd El- Malak

open access: yesAssiut Veterinary Medical Journal, 2007
Cryopreservation induces partially irreversible damage to sperm membrane as a result of membrane destabilization.  The membrane damage after freezing might be linked to the modification of the membrane fluidity before freezing.

S6 peptide derived from KvAP channel shows cooperativity in gating on bilayer lipid membrane. [PDF]

open access: yesPLoS ONE, 2013
Collective behavior of S6 peptide channels derived from KvAP (a bacterial potassium channel) incorporated in lipid bilayer membrane, has been investigated at various applied potentials through multi-channel electrophysiological experiments.

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 ...

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.

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 ...
