The influence of naphthenic acids and their fractions onto cell membrane permeability [PDF]

Journal of the Serbian Chemical Society, 2015
The influence of naphthenic acids (NAs) mixture and their narrow fractions (called NA pH 4, pH 8 and pH 10) onto permeability of beetroot cell membrane is examined.

Phosphatidylserine Exposed Lipid Bilayer Models for Understanding Cancer Cell Selectivity of Natural Compounds: A Molecular Dynamics Simulation Study

Membranes, 2022
Development of drugs that are selectively toxic to cancer cells and safe to normal cells is crucial in cancer treatment. Evaluation of membrane permeability is a key metric for successful drug development.

Permeability of the liver cell membrane to quinolinate [PDF]

Biochemical Journal, 1977
Quinolinate was taken up by both rat and guinea-pig liver cells. Equilibrium was reached after approx. 20 min with rat cells, but guinea-pig cells had not achieved a steady state after 60 min. There was no evidence to suggest that quinolinate is rapidly metabolized by either species.

Systematic comparison of unilamellar vesicles reveals that archaeal core lipid membranes are more permeable than bacterial membranes.

PLoS Biology, 2023
One of the deepest branches in the tree of life separates the Archaea from the Bacteria. These prokaryotic groups have distinct cellular systems including fundamentally different phospholipid membrane bilayers.

Significance of two transmembrane ion gradients for human erythrocyte volume stabilization.

PLoS ONE, 2022
Functional effectiveness of erythrocytes depends on their high deformability that allows them to pass through narrow tissue capillaries. The erythrocytes can deform easily due to discoid shape provided by the stabilization of an optimal cell volume at a ...

CO2 permeability of the rat erythrocyte membrane and its inhibition

Journal of Enzyme Inhibition and Medicinal Chemistry, 2021
We have studied the CO2 permeability of the erythrocyte membrane of the rat using a mass spectrometric method that employs 18 O-labelled CO2. The method yields, in addition, the intraerythrocytic carbonic anhydrase activity and the membrane HCO3 ...

Fusogenic structural changes in arenavirus glycoproteins are associated with viroporin activity.

PLoS Pathogens, 2023
Many enveloped viruses enter host cells by fusing with acidic endosomes. The fusion activity of multiple viral envelope glycoproteins does not generally affect viral membrane permeability.

Donnan Potential across the Outer Membrane of Gram-Negative Bacteria and Its Effect on the Permeability of Antibiotics

Antibiotics, 2021
The cell envelope structure of Gram-negative bacteria is unique, composed of two lipid bilayer membranes and an aqueous periplasmic space sandwiched in between.

Comparative study on cell membrane permeability of SDS and Triton X-100

He jishu, 2022
BackgroundSodium dodecyl sulfate (SDS) and polyethylene glycol octyl phenyl ether (Triton X-100) are commonly used for surfactants in the laboratory, which can dissolve lipids in the cell membrane, increase the permeability of cell membrane, and can ...
