In chordates, intercellular communication based on gap junctions relies on channels formed by protein subunits of the connexin family, whose members are named according to their molecular mass 1.

From a consideration of the methods heretofore used in the study of permeability it would appear that the steps most essential to further progress toward the solution of the problem are: (1) a ...

Abstract The gas flow mechanisms in source rocks of coal measures under the effects of the pore structures and permeability characteristics were investigated by field-emission scanning electron ...

For decades, scientists across the globe have investigated methods to accurately measure drug permeability across the blood-brain barrier, a compact layer of cells that protect the brain from ...
