The process of the present disclosure, for instance, can increase the ion permeability of membranes and/or the gas permeability of membranes.

The ionic agent (140) will cause a temporary change in ion permeability of the tissue cell membranes and a depolarization of the tissue cells.

The multiple thin films (6B, 6C) have different ion permeability values from each other.

These novel compounds impart ion permeability to phospholipid bilayers and also modulate cellular volume in mammalian cells in vitro.

The manufacturing method requires the oxygen concentration of the polymerizable material to be low enough to produce a lens having a high ion permeability.

This allows students to explore the relationship between ionic concentrations and equilibrium potentials, and relative ionic permeability and the membrane potential.

The dye-binding step determines if the increase in ionic permeability is due to physical destruction of the stratum corneum.

The dye-binding step determines if the increase in ionic permeability is due to physical destruction of the stratum corneum.

A dye-binding step incorporated into the test procedure permits the determination of whether or not increases in ionic permeability are due to physical destruction of the stratum corneum.
