WebFluctuations in dentin permeability as an effect of storage medium and duration have been reported in previous studies. 32, 33 One of the studies showed that the dentin slabs presented increased permeability after 90 days stored in deionized water. 32 In general, there seems to be a tendency for increased dentin permeability due to washing out ...
WebAug 18, 2016 · The "pull" effect of borneol also improved drug permeation. However, for a strongly hydrophobic drug like osthole, the permeation enhancement of borneol was limited. When most borneol molecules permeated into bilayers and were located at the hydrophobic tail region, the spatial competition effect inhibited drug molecules from permeating … WebAug 24, 2024 · In next work, the correlation between gas permeation and diffusion coefficient should be studied for one polymer with different filler contents, that is, the effect of filler concentration on ...
WebFinally, the permeation effect induced by the MNs was demonstrated by insulin delivery in vivo. The blood glucose levels of diabetic mice were reduced to 29% of initial level at 5 h due to the increased permeability of insulin to the skin after MNs insertion.
