TLDR
The equations derived here have been applied to various permeability measurements found in the literature, such as the penetration of heavy water into animal cells, permeability of blood vessels, threshold concentration of plasmolysis and relaxation experiments with artificial membranes.About:

Permeability properties of the membrane of vesicular stomatitis virions
TL;DR: The osmotic barrier in intact vesicular stomatitis virions may not be exclusively lipid in nature, andFilipin treatment caused structural changes in the viral membrane, revealing appreciably larger responses to osmosis change than did protease-treated virus particles.

The permeability of the gastric mucosa of dog.
M. Altamirano,C. Martinoya +1 more
TL;DR: The permeability of a semi‐isolated piece of the great curvature of the canine stomach is studied using Tritiated water,urea, Thiourea, sucrose, and [59Fe]‐haemoglobin.

Hydraulic permeability and activation energy of human keratinocytes at subzero temperatures.
TL;DR: Studies on isolated human keratinocytes provide a model for design of optimal freeze-thaw protocols for skin cryopreservation and banking and changes in the apparent cell volume were quantified over a period of several minutes to obtain dehydration curves associated with exposure to concentrated extracellular electrolytes.

Transport Models for Ion-Exchange Membranes
TL;DR: The use of ion exchange membranes in electrochemical devices is advantageous because membrane systems offer a simple and durable technique for performing functions that would otherwise be impossible or require more cumbersome and energy-intensive methodologies as discussed by the authors.

A Porous Media Approach for Analyzing a Countercurrent Dialyzer System
Yoshihiko Sano,Akira Nakayama +1 more
TL;DR: A porous media approach based on the volume-averaging theory has been proposed to investigate solute diffusion and ultrafiltration processes associated with hemodialysis using a hollow fiber membrane dialyzer to establish a three concentration equation model.

Filtration, diffusion and molecular sieving through peripheral capillary membranes; a contribution to the pore theory of capillary permeability.
TL;DR: Theoretical and experimental studies on the sieving of molecules by ultrafiltration through porous membranes indicate that an effective pore diameter of at least IOO A would be required to explain permeability of this magnitude.
Journal ArticleDOI
Passage of Molecules Through Capillary Walls
TL;DR: A wealth of evidence supports the view that the exchange of materials through the walls of living capillaries takes place by physical processes which involve no expenditure of energy on the part of the capillary endothelial cells themselves.
