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:

Peritoneal physiology-transport of solutes
Bengt Rippe,Raymond T. Krediet +1 more
TL;DR: The peritoneal cavity, which lodges the abdominal viscera, represents the largest serosal cavity in the body and can be rather effectively utilized as an endogenous dialysis membrane to remove uremic toxins and water from the body fluids of patients with end-stage renal disease duringperitoneal dialysis (PD).

Determination of Hydraulic and Osmotic Properties of Soybean Root Systems
TL;DR: An analytical technique which allows the experimental determination of soybean (Glycine max L.) root properties is presented and it is shown that root flow rates necessary to sustain high transpiration rates in the shoots are easily accommodated by the model at moderate levels of applied pressure difference.

TL;DR: Translocation of phototransduction components out of the OS may protect rods from osmotic stress, which could be especially harmful in disease conditions that affect rod OS structural integrity.

The magnitude of nonelectrolyte selectivity in the gallbladder epithelium
TL;DR: There was a good agreement between the selectivity sequences obtained by the two methods for the sixteen compounds used in this study, and although the permeability coefficients are directly related to their bulk-phase partition coefficients, the gallbladder behaves as if the membranes controlling selectivity are more hydrophilic than isobutanol.

Water permeability of oil layers in W/O/W emulsions under osmotic pressure gradients
TL;DR: Water permeability of oil layers in a series of water/hydrocarbon/water emulsions has been studied microscopically by measuring the rate of change in the size of the dispersed globules as discussed by the authors.

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.
