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:

How the house sparrow Passer domesticus absorbs glucose.
TL;DR: In house sparrows Passer domesticus, a pharmacokinetic method was applied to measure simultaneous in vivo absorption of [14C]l-glucose and [3H]3OMd-glUCose in a situation in which intestinal glucose transporters were relatively saturated and the apparent rate of absorption was significantly reduced.

Numerical simulation of chloride penetration in concrete in rapid chloride migration tests
TL;DR: In this article, double porosity was used to reflect the influence of pore size distribution on the transport of ionic species in porous materials, and a new transport model was presented for describing the penetration of chlorides in cement-based materials.
Journal ArticleDOI
Evidence for a glycerol pathway through aquaporin 1 (CHIP28) channels.
TL;DR: The urea exclusion suggests that the selectivity of the AQP1 channels not only depends on the size of the solutes but probably also on their flexibility and their ability to form H-bonds.

Mechanobiology of low-density lipoprotein transport within an arterial wall—Impact of hyperthermia and coupling effects
Stephen Chung,Kambiz Vafai +1 more
TL;DR: It is shown that hyperthermia results in an enhancement in LDL transport by increasing the concentration levels within the arterial wall by incorporating the variations in the effective LDL diffusivity and consumption rate, as well as other dominating parameters.

Mechanism by Which Glucose Stimulates the Passive Absorption of Small Solutes by the Human Jejunum In Vivo
TL;DR: When glucose stimulates the passive absorption of L-xylose, 57% of the increase can be attributed to solvent drag and 42% to passive diffusion, which can be explained by glucose-induced water absorption.

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.
