Water permeability (Lp), calculated from the volume variations of cells subjected to an osmotic shock, is classically used to characterize cell membrane properties. In this work, we have shown the importance of the kind of mixing reactor used to measure the Lp parameter. A mathematical model including the mixing time constant has been proposed allowing

Cell Membrane Permeability and Hypertension
1984A great deal of evidence has been presented which suggests that a generalized increase in cell membrane permeability to various ions is a fundamental defect associated with hypertension. In addition, some of the evidence is supportive of a central role of this defect in the pathogenesis of hypertension.

Permeability of the Cell-to-Cell Membrane Channels in Mammalian Cell Junction
Science, 1979The channels in the junctions of various mammalian cell types—primary cultures and lines—were probed with a series of linear fluorescent amino acid and peptide molecules of different size and charge. Permeability is limited by probe size and electronegativity, these two factors apparently being related reciprocally.

Paraquat Induces Cell Death Through Impairing Mitochondrial Membrane Permeability
Molecular Neurobiology, 2015Paraquat (PQ) as a Parkinsonian mimetic has been demonstrated to impair dopaminergic (DAergic) neurons and is highly correlated with the etiology of Parkinson's disease (PD) where the death of DAergic neurons has been mainly attributed to impaired mitochondrial functioning.

The Cell Membrane and Ionic Permeability
1991All living cells are surrounded by a cell membrane which separates the cellular contents from the outside medium. The organized contents of the cell, including the nucleus and such organelles as the mitochondria, Golgi apparatus, lysosomes, the endoplasmic reticulum, as well as the components of the cytoskeleton, exist in a watery medium — the ...

The Temperature Peaks of Cell Membrane Permeability
1987Any change in the structural organization of the cell membrane as the main permeation barrier, should be reflected in its transport behaviour. Studies of the temperature dependence of cellular water transport should therefore provide valuable information on the structural dynamics of the membrane.

Endothelial cells grown on permeable membrane supports
Journal of Tissue Culture Methods, 1992Endothelial cells from a variety of vascular beds can be isolated, purified, grown in culture, passaged, and established as a confluent monolayer on membrane supports. The culture of endothelial cells from porcine pulmonary artery, porcine aorta, porcine coronary arteries, bovine adipose tissue microvessels, human foreskin microvessels, and human ...

Pharmacological receptors and general permeability phenomena of cell membranes
Journal of Theoretical Biology, 1965Abstract The similarity in structure and charge distribution of acetyl choline (ACh), γ-aminobutyric acid (GABA) and glutamic acid to the “polar head groups” of lecithin, phosphatidylethanolamine, and phosphatidylserine, respectively, is used as the basis of an hypothesis to explain the pharmacological actions of the former three substances.
