Asymmetrically Permeable Membrane Channels in Cell Junction
Science, 1980Asymmetric membrane junctions were formed in culture by pairing two cell types which, in their respective homologous junctions, have cell-cell channels of different permselectivities. The channels in the asymmetric junction, presumably made of unequal channel precursors, displayed directional permselectivity; fluorescent labeled glutamic acid (700 ...

Membrane permeability of isolated lung cells to nonelectrolytes
American Journal of Physiology-Cell Physiology, 1977Mixtures of viable endothelial and epithelial cells were separated by enzymatic digestion from rabbit lung and recovered by centrifugation. The cells were mixed with an extracellular marker and packed by centrifugation into small-diameter polyethylene tubing and pulsed with tritiated water and 14C-labeled alcohols.

Cell membrane permeability in hypertension.
Clinical physiology and biochemistry, 1989A 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.

The Nanopore Connection to Cell Membrane Unitary Permeability
Traffic, 2005Artificial nanopores have recently emerged as versatile tools for analyzing and sorting single molecules at high speed. However, the biological cell has already developed a large set of sophisticated protein nanopores that are able to selectively translocate all types of molecules through membranes.

The Permeability of Plant Cell Membrane to Sugar
Nature, 1929THIS communication deals with a glucose effect on the permeability of cell membranes to sugar molecules as studied by the intensity of respiration when leaves of Artocarpus Integrifolia were injected with varying concentrations of glucose solution.

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.

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.

Electrogenic systems of a cell and membrane permeability
Bioelectrochemistry and Bioenergetics, 1983Summary The equation of membrane potential (Δψ) for electrogenic cation pump operation has been developed. The expression obtained can be equally used for the description of Δψ created by any electrogenerator that transduces light or chemical energy into electrochemical potential difference.
