In vivo perfusion studies of the cloacal water and electrolyte resorption in the fowl (Gallus domesticus)
TL;DR: The resorption of salt and water in the coprodeum and large intestine of the chicken was investigated by means of an in vivo perfusion technique and a marked rectification of the hydraulic conductivity was observed in the experiments with impermeant solute.
Journal ArticleDOI
The effect of varying albumin concentration of the hydraulic conductivity of the rabbit common carotid artery.
TL;DR: In this article, rabbit common carotid arteries were cannulated in situ, after ligation of their branches, and transferred to a perfusion apparatus in such a way that they were maintained at their physiological dimensions and the endothelium remained intact.

Effects of Percoll Separation, Cryoprotective Agents, and Temperature on Plasma Membrane Permeability Characteristics of Murine Spermatozoa and Their Relevance to Cryopreservation
M.J. Phelps,Jun Liu,Jun Liu,James D. Benson,C.E. Willoughby,J.A. Gilmore,J.A. Gilmore,John K. Critser,John K. Critser +8 more
TL;DR: Strain-specific methods for CPA addition and removal based upon the fundamental cryobiological characteristics of murine spermatozoa resulted in higher survivals than current methods or procedures, which were used as controls.

Transport of salt mixtures through nanofiltration membranes: Numerical identification of electric and dielectric contributions
TL;DR: In this paper, a knowledge model is used to describe the rejection of ionic components in various proportions obtained by mixing two salts (NaCl and Na 2 SO 4 or NaCl and MgCl 2 ).
Journal ArticleDOI
Modeling of ultrafiltration process for a two-component aqueous solution of low and high (gel-forming) molecular weight solutes
TL;DR: In this paper, a mathematical model was formulated for simultaneous prediction of permeate flux and observed rejection of sucrose in a stirred ultrafiltration cell, and the characteristics of the gel layer and other relevant parameters of the model were determined by independent sets of experiments.

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.
