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

Fluctuation spectra of free and supported membrane pairs [PDF]
European 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.

On the accuracy of cell-attached current-clamp recordings from cortical neurons
Frontiers in Molecular Neuroscience, 2022 Cell-attached current-clamp (CA/CC) recordings have been proposed to measure resting membrane potential and synaptic/agonist responses in neurons without disrupting the cell membrane, thus avoiding the intracellular dialysis that occurs in conventional ...

The microbiologist’s guide to membrane potential dynamics [PDF]
, 2020 All cellular membranes have the functionality of generating and maintaining the gradients of electrical and electrochemical potentials. Such potentials were generally thought to be an essential but homeostatic contributor to complex bacterial behaviors ...

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.

BRANEart: Identify Stability Strength and Weakness Regions in Membrane Proteins
Frontiers in Bioinformatics, 2021 Understanding the role of stability strengths and weaknesses in proteins is a key objective for rationalizing their dynamical and functional properties such as conformational changes, catalytic activity, and protein-protein and protein-ligand ...
