PURPOSE Anti-vascular endothelial growth factor (VEGF) antibody therapy is an effective treatment for ocular angiogenesis. Although the intraocular pressure of some patients increases after anti-VEGF therapy, the effects of VEGF-A on the aqueous humor outflow pathway remain unknown. This study investigated the effects of VEGF-A on the aqueous humor outflow pathway. METHODS We used human recom...

The effect of whole leaf and gel materials from two aloe species (Aloe vera and A. ferox) was compared with that of the precipitated polysaccharides from these aloe materials on the transepithelial electrical resistance (TEER) as well as transport of a model compound (atenolol) in the apical-to-basolateral direction across rat intestinal tissue. All the aloe leaf materials and precipitated poly...

We have developed a bilayer microfluidic system with integrated transepithelial electrical resistance (TEER) measurement electrodes to evaluate kidney epithelial cells under physiologically relevant fluid flow conditions. The bioreactor consists of apical and basolateral fluidic chambers connected via a transparent microporous membrane. The top chamber contains microfluidic channels to perfuse ...

Abstract Funding Acknowledgements Type of funding sources: None. Introduction Transcatheter edge-to-edge mitral valve repair (TEER) with the MitraClip system has emerged as a therapeutic alternative to surgical solutions in high risk patients severe regurgitation (MR). MR is characterized by left ventricular volume overload, which leads dilatation. Furthermore, common cause pulmonary hypertensi...

Transcatheter edge-to-edge repair (TEER) currently represents a valuable therapeutic option for patients with severe mitral regurgitation (MR) considered at high surgical risk. Besides symptoms and left ventricular (LV) echocardiographic improvements upon TEER, it has been postulated that atrial (LA) function plays prognostic role. The aims of our study were to evaluate LA changes after measure...

Abstract Funding Acknowledgements Type of funding sources: None. Background Transcatheter cardiac valve procedures, including transcatheter aortic replacement (TAVR) and edge-to-edge repair (TEER), have increased in the recent years. Peri-procedural management strategies, whether there is a need for routine admission to intensive care units (CICUs), are not well defined. Purpose We aimed descri...

Prolonged hypoxia produces reversible changes in endothelial permeability, but the mechanisms involved are not fully known. Previous studies have implicated reactive oxygen species (ROS) and cytokines in the regulation of permeability. We tested whether prolonged hypoxia alters permeability to increasing ROS generation, which amplifies cytokine production. Human umbilical vein endothelial cell ...

Skin is a critical organ that plays a crucial role in defending the internal organs of the body. For this reason, extensive work has gone into creating artificial models of the epidermis for in vitro skin toxicity tests. These tissue models, called reconstructed human epidermis (RhE), are used by researchers in the pharmaceutical, cosmetic, and environmental arenas to evaluate skin toxicity upo...

The aim of this research was to identify bacterial isolates having the potential to improve intestinal barrier function. Lactobacillus plantarum strains and human oral isolates were screened for their ability to enhance tight junction integrity as measured by the transepithelial electrical resistance (TEER) assay. Eight commercially used probiotics were compared to determine which had the great...

Background: Concomitant mitral transcatheter edge-to-edge repair (M-TEER) and left atrial appendage closure (LAAC) showed to be a feasible approach optimize the treatment of patients eligible for both procedures, but mid-term outcomes are unclear. Methods: We retrospectively analyzed consecutive undergoing M-TEER enrolled in local prospective Getting Reduction Mitral Insufficiency by Percutaneo...
