Membrane water for probing neuronal membrane potentials and ionic fluxes at the single cell level. [PDF]
Nat Commun, 2018 Neurons communicate through electrochemical signaling within a complex network. These signals are composed of changes in membrane potentials and are traditionally measured with the aid of (toxic) fluorescent labels or invasive electrical probes. Here, we

Individual cristae within the same mitochondrion display different membrane potentials and are functionally independent. [PDF]
EMBO J, 2019 The mitochondrial membrane potential (ΔΨm) is the main driver of oxidative phosphorylation (OXPHOS). The inner mitochondrial membrane (IMM), consisting of cristae and inner boundary membranes (IBM), is considered to carry a uniform ΔΨm.

SODIUM, POTASSIUM, AND CHLORIDE TRANSPORT AND MEMBRANE POTENTIALS IN VALONIA VENTRICOSA
, 1966 1. The marine alga Valonia ventricosa regulates its ionic content by means of several ion pumps. An active extrusion of Na+ and probably an active uptake of K+ occur at the plasmalemma.

Mitochondrial membrane potential [PDF]
Analytical Biochemistry, 2018 The mitochondrial membrane potential (ΔΨm) generated by proton pumps (Complexes I, III and IV) is an essential component in the process of energy storage during oxidative phosphorylation. Together with the proton gradient (ΔpH), ΔΨm forms the transmembrane potential of hydrogen ions which is harnessed to make ATP.

Membrane potential and cancer progression [PDF]
Frontiers in Physiology, 2013 Membrane potential (Vm ), the voltage across the plasma membrane, arises because of the presence of different ion channels/transporters with specific ion selectivity and permeability. Vm is a key biophysical signal in non-excitable cells, modulating important cellular activities, such as proliferation and differentiation.

The membrane potential of Giardia intestinalis [PDF]
FEMS Microbiology Letters, 2000 Giardia intestinalis is a primitive microaerophilic protozoan parasite which colonises the upper intestine of humans. Despite the evolutionary and medical significance of this organism, its physiology is very poorly understood. In this study we have used a novel flow cytometric technique to make quantitative measurements of the electrical potential ...
