Positively charged mineral surfaces promoted the accumulation of organic intermediates at the origin of metabolism. [PDF]

open access: yesPLoS Computational Biology, 2022
Identifying plausible mechanisms for compartmentalization and accumulation of the organic intermediates of early metabolic cycles in primitive cells has been a major challenge in theories of life's origins.

Individual cristae within the same mitochondrion display different membrane potentials and are functionally independent. [PDF]

open access: yesEMBO 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.

Synaptic NMDA receptor activity at resting membrane potentials [PDF]

open access: yesFrontiers in Cellular Neuroscience, 2022
NMDA receptors (NMDARs) are crucial for glutamatergic synaptic signaling in the mammalian central nervous system. When activated by glutamate and glycine/D-serine, the NMDAR ion channel can open, but current flux is further regulated by voltage-dependent

Effects of membrane potentials on the electroporation of giant unilamellar vesicles. [PDF]

open access: yesPLoS ONE, 2023
Living organisms maintain a resting membrane potential, which plays an important role in various biophysical and biological processes. In the context of medical applications, irreversible electroporation (IRE) is a non-thermal and minimally invasive ...

Fluctuation spectra of free and supported membrane pairs [PDF]

open access: yesEuropean Physical Journal E 23, 103-116 (2007), 2006
Fluctuation spectra of fluid compound membrane systems are calculated. The systems addressed contain two (or more) almost parallel membranes that are connected by harmonic tethers or by a continuous, harmonic confining potential. Additionally, such a compound system can be attached to a supporting substrate.

SODIUM, POTASSIUM, AND CHLORIDE TRANSPORT AND MEMBRANE POTENTIALS IN VALONIA VENTRICOSA

open access: green, 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.
