The blood-brain barrier (BBB), the blood-retinal barrier (BRB), and the blood-nerve barrier (BNB) may have similarities in systemic chronic inflammation, as seen in a variety of diseases. A disturbance of the barriers lead to a disruption of the cells coupled with gap junctions in syncytium. The network coupling may be principal to understand the homeostatic imbalance in systemic inflammation. ...

In this paper, we give a recursive formula for optimal dual barrier functions on homogeneous cones. This is done in a way similar to the primal construction of Güler and Tunçel [1] by means of the dual Siegel cone construction of Rothaus [2]. We use invariance of the primal barrier function with respect to a transitive subgroup of automorphisms and the properties of the duality mapping, which i...

Context: This article reviews the available evidence about the barrier membranes utilized in Guided Tissue Regeneration process to prevent the migration of unfavorable cells to the wound area. Evidence Acquisition: Available evidence about membranes properties and their different uses were reviewed, and the results of clinical and animal studies and systematic reviews were gathered. Results: A ...

This review focuses on the intricate properties of the glomerular barrier. Other reviews have focused on podocyte biology, mesangial cells, and the glomerular basement membrane (GBM). However, since all components of the glomerular membrane are important for its function, proteinuria will occur regardless of which layer is affected by disease. We review the properties of endothelial cells and t...

The SonoPrep(R) ultrasonic skin permeation system is used clinically to increase skin permeability for rapid, noninvasive delivery of local anaesthetics. This study tested the hypothesis that sonication can generate a long-lived increase of skin permeability for continuous transdermal drug delivery and diagnostic metabolite extraction. To accomplish this, the volar forearm skin of ten healthy a...
