Modulatory Effects of Acidic pH and Membrane Potential on the Adsorption of pH-Sensitive Peptides to Anionic Lipid Membrane

open access: yesMembranes, 2021
Anionic lipid membrane electrostatic potential and solution pH can influence cationic peptide adsorption to these bilayers, especially those containing simultaneously acid and basic residues.

Modulation of the ISFET response by an immunological reaction [PDF]

open access: yes, 1989
A new method is presented for the detection of an immunological reaction in a membrane. Antigens (or antibodies) are taken up in a porous membrane, which covers the gate area of an ISFET. By stepwise changing of the electrolyte concentration, a transient

Macroscopic control of cell electrophysiology through ion channel expression

open access: yeseLife, 2022
Cells convert electrical signals into chemical outputs to facilitate the active transport of information across larger distances. This electrical-to-chemical conversion requires a tightly regulated expression of ion channels.

A Novel Calcium-Activated Potassium Channel Controls Membrane Potential and Intracellular pH in Trypanosoma cruzi

open access: yesFrontiers in Cellular and Infection Microbiology, 2020
Trypanosoma cruzi develops in environments where nutrient availability, osmolarity, ionic concentrations, and pH undergo significant changes. The ability to adapt and respond to such conditions determines the survival and successful transmission of T ...

A low-voltage activated, transient calcium current is responsible for the time-dependent depolarizing inward rectification of rat neocortical neurons in vitro [PDF]

open access: yes, 1987
Intracellular recordings were obtained from rat neocortical neurons in vitro. The current-voltage-relationship of the neuronal membrane was investigated using current- and single-electrode-voltage-clamp techniques.

Calcium Signaling in Plant-Insect Interactions

open access: yesPlants, 2022
In plant–insect interactions, calcium (Ca2+) variations are among the earliest events associated with the plant perception of biotic stress. Upon herbivory, Ca2+ waves travel long distances to transmit and convert the local signal to a systemic defense ...

Cromakalim (BRL 34915) restores in vitro the membrane potential of depolarized human skeletal muscle fibres [PDF]

open access: yes, 1989
The purpose of the present study was to analyze the effects of cromakalim (BRL 34915), a potent drug from a new class of drugs characterized as K+ channel openers, on the electrical activity of human skeletal muscle.

Ling’s Adsorption Theory as a Mechanism of Membrane Potential Generation Observed in Both Living and Nonliving Systems

open access: yesMembranes, 2016
The potential between two electrolytic solutions separated by a membrane impermeable to ions was measured and the generation mechanism of potential measured was investigated.

Membrane structures and their use in civil engineering [PDF]

open access: yes, 2018
This paper is focused on the static analysis of membrane structures, which are typical for their ability to transfer only tensile forces. Membrane structures are becoming more popular owing to their lower initial cost and potential for use in ...

Membrane Potential Assessment by Fluorimetry as a Predictor Tool of Human Sperm Fertilizing Capacity

open access: yesFrontiers in Cell and Developmental Biology, 2020
Mammalian sperm acquire the ability to fertilize eggs by undergoing a process known as capacitation. Capacitation is triggered as the sperm travels through the female reproductive tract.
