Determination of pore size and pore size distribution on the surface of hollow-fiber filtration membranes : a review of methods
TL;DR: In this article, various methods to characterize the pore size and pore distribution of hollow-fiber porous filtration membranes were reviewed, including microscopy observation, thermoporometry, and water permeability.

Concentration of solutes in the renal inner medulla: interstitial hyaluronan as a mechano-osmotic transducer.
TL;DR: A theoretical basis for classifying all possible steady-state inner medullary countercurrent concentrating mechanisms based on mass balance principles is summarized and the Schmidt-Nielsen hypothesis that the contractions of the renal pelvocalyceal wall may provide an important energy source for concentration in the inner medulla is expanded.

The pressure-dependence of the hydraulic conductivity, the membrane resistance and membrane potential during turgor pressure regulation in Valonia utricularis.
U. Zimmermann,E. Steudle +1 more
TL;DR: It is suggested that the electrogenic potassium pump postulated by Gutknecht is pressure-dependent and causes the observed changes in membrane resistance and that this pump reverses its direction at high pressures.

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.
