The purpose of the present prospective randomized study was to evaluate the influence of Laser-Lok microtextured surface on soft tissue periimplant parameters and esthetics around immediate, functionally loaded implants for single-tooth replacement in the esthetic zone. This study included 77 patients divided into two groups based on different implants used: the control group had BioHorizons ta...
PURPOSE To determine the localization of JAM-C in human RPE and characterize its functions. METHODS Immunofluorescence, Western blot, and PCR was used to identify the localization and expression of JAM-C, ZO-1, N-cadherin, and ezrin in cultures of human fetal RPE (hfRPE) with or without si-RNA mediated JAM-C knockdown and in adult native RPE wholemounts. A transepithelial migration assay was ...
Eimeria spp. are intracellular protozoa that infect intestinal epithelia of most vertebrates, causing coccidiosis. Intestinal intraepithelial lymphocytes (IEL) that reside at the basolateral site of epithelial cells (EC) have immunoregulatory and immunoprotective roles against Eimeria spp. infection. However, it remains unknown how IEL are involved in the regulation of epithelial barrier during...
It has previously been shown that the monoclonal antibody anti-Arc-1 dissociates Madin-Darby canine kidney (MDCK) epithelial cells and changes their morphology in vitro (Imhof, B.A., H.P. Vollmers, S.L. Goodman, and W. Birchmeier, 1983, Cell, 35:667-675). In this article we demonstrate that the anti-Arc-1 antibody recognizes an uvomorulin-like molecule on MDCK cells, i.e., it immunoprecipitates...
we present a case of epitheloid sarcoma that was referred with a 2×3cm ulcerated lesion on the right ankle and edema of the lower leg. foot drop of the right side was present that had caused walking difficulty. after a few months, he developed several sporthricoidal nodular lesions on the medial aspect of right thigh, inguinal lymphadenopathy, weight loss, anorexia and respiratory symptoms. che...
The mechanisms of apparent streaming potentials elicited across Necturus gallbladder epithelium by addition or removal of sucrose from the apical bathing solution were studied by assessing the time courses of: (a) the change in transepithelial voltage (Vm,), (b) the change in osmolality at the cell surface (estimated with a tetrabutylammonium [TBA+]-selective microelectrode, using TBA + as a tr...
The effects of Corexit 9500A (CE) on respiratory epithelial surfaces of terrestrial mammals and marine animals are largely unknown. This study investigated the role of CE-induced heme oxygenase-1 (HO-1), a cytoprotective enzyme with anti-apoptotic and antioxidant activity, in human bronchial airway epithelium and the gills of exposed aquatic animals. We evaluated CE-mediated alterations in huma...
Neutrophil-mediated injury to gut epithelium may lead to disruption of the epithelial barrier function with consequent organ dysfunction, but the mechanisms of this are incompletely characterized. Because the epithelial apical junctional complex, comprised of tight and adherens junctions, is responsible in part for this barrier function, we investigated the effects of neutrophil transmigration ...
