PERMEABILITY AND FUNCTION OF BIOLOGICAL MEMBRANES

Permeability and Function of Biological Membranes

with the history of cardiac surgery, there may be difficulty in finding the reference to a particular point. Usually, however, the major points are indexed and it is only ones ancillary to cardiac surgery that one must search for. The margins are liberally sprinkled with line drawings of many of the pioneers. The sketches add charm to the presentation, even though they are not always good liken...

Measurement of the Permeability of Biological Membranes

The transport equation describing the flow of solute across a membrane has been modified on the basis of theoretical studies calculating the drag of a sphere moving in a viscous liquid undergoing Poiseuille flow inside a cylinder. It is shown that different frictional resistance terms should be introduced to calculate the contributions of diffusion and convection. New sieving equations are deri...

Biological Membranes Architecture and Function

CO2 Permeability of Biological Membranes and Role of CO2 Channels

We summarize here, mainly for mammalian systems, the present knowledge of (a) the membrane CO₂ permeabilities in various tissues; (b) the physiological significance of the value of the CO₂ permeability;

On the Effective Permeability of Mixed Matrix Membranes

Mixed matrix membranes (MMMs) are attracting significant interest for pervaporation and gas separation applications. To better comprehend the impact of filler particles within polymer matrices, the species permeation mass transport was theoretically studied by numerical simulation using finite differences. The Fick’s second law of diffusion was solved for a three-dimensional MMM to obtain the c...
