Permeability of a Cell Membrane Junction [PDF]

The Journal of General Physiology, 1969
The ion permeability of the membrane junctions between Chironomus salivary gland cells is strongly depressed by treatments that are generally known to inhibit energy metabolism. These treatments include prolonged cooling at 6°–8°C, and exposure to dinitrophenol, cyanide, oligomycin, and N-ethylmaleimide.

Acetaminophen Changes Intestinal Epithelial Cell Membrane Properties, Subsequently Affecting Absorption Processes

Cellular Physiology and Biochemistry, 2013
Background/Aims: Acetaminophen (APAP) effects on intestinal barrier properties are less investigated. APAP may lead to a changed bioavailability of a subsequently administered drug or diet in the body. We investigated the influence of APAP on enterocytic

Continuous wave irradiation at 0.1 terahertz facilitates transmembrane transport of small molecules

iScience, 2022
Summary: The bioeffects of terahertz (THz) radiation received growing attention because of its influence on the interactions between biomolecules. Our work aimed to investigate the effects of THz irradiation on cell membrane, especially cell membrane ...

Lens Cell Membrane Permeability and Cataract Formation.

Experimental Biology and Medicine, 1964
SummaryAnalyses of rat lenses just before and just after the appearance of diabetic or galactose cataracts demonstrate that this event is accompanied by an abrupt disruption of the cell membranes of the lens. The concentrations of polyol, glucose and fructose in the lens approach those in the blood; and the extracellular space as determined with ...

Effect of proanthocyanidins on cell membrane properties of Saccharomyces cerevisiae [PDF]

Zhongguo niangzao
In order to investigate the action mechanism of proanthocyanidins from the perspective of cell membrane, the effects of 0.5 g/L and 1.0 g/L proanthocyanidins on the characteristics of the cell membrane of Saccharomyces cerevisiae were studied.

Determination of cell membrane permeability in concentrated cell ensembles

Biophysical Journal, 1987
The method of volume averaging is used to analyze the process of diffusion in concentrated cell ensembles in which significant resistance to mass transfer is caused by the cellular membrane. A general closure scheme is given that allows for direct theoretical prediction of effective diffusivities for any cellular geometry.

P2X7 Receptor Mediated Increase In Cell Membrane Permeability

Ankara Üniversitesi Tıp Fakültesi Mecmuası, 2018
Purinergic receptors consist of two main families; P2X and P2Y. P2Y receptors are G protein coupled receptors (GPCR), whereas P2X receptors are non-selective cation channels. P2X7 receptors which is a member of P2X receptors, have been found myriad types

Capsid protein VP4 of human rhinovirus induces membrane permeability by the formation of a size-selective multimeric pore.

PLoS Pathogens, 2014
Non-enveloped viruses must deliver their viral genome across a cell membrane without the advantage of membrane fusion. The mechanisms used to achieve this remain poorly understood. Human rhinovirus, a frequent cause of the common cold, is a non-enveloped

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.

Autophagic cell death is dependent on lysosomal membrane permeability through Bax and Bak

eLife, 2017
Cells deficient in the pro-death Bcl-2 family members Bax and Bak are known to be resistant to apoptotic cell death, and previous we have shown that these two effectors are also needed for mitochondrial-dependent cellular necrosis (Karch et al., 2013 ...
