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 ...

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.

Diffusion in the Presence of Cells with Semi-permeable Membranes [PDF]
Journal of Statistical Physics, 2020 We consider processes that coincide with a given diffusion process except on the boundaries of a finite collection of domains. The behavior on each of the boundaries is asymmetric: the process is much more likely to enter the interior of the domain than to enter the interior of its complement, with a small parameter controlling the trapping mechanism ...

Cellular EXchange Imaging (CEXI): Evaluation of a diffusion model including water exchange in cells using numerical phantoms of permeable spheres [PDF]
Magn Reson Med. 2023; 1- 16, 2023 Purpose: Biophysical models of diffusion MRI have been developed to characterize microstructure in various tissues, but existing models are not suitable for tissue composed of permeable spherical cells. In this study we introduce Cellular Exchange Imaging (CEXI), a model tailored for permeable spherical cells, and compares its performance to a related ...

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 ...

Inactivation Effect and Mechanism of Plasma Activated Water on Shewanella putrefaciens [PDF]
Shipin Kexue, 2023 In this study, the bactericidal effect and mechanism of plasma activated water (PAW) against Shewanella putrefaciens, a common microorganism found in aquatic products, were investigated by plate counting, fluorescence staining and scanning electron ...

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.
