1. Increased expression levels of Syntaxin 1A and Synaptobrevin 2/Vesicle-Associated Membrane Protein-2 are associated with the progression of bladder cancer
Abstract Gene expression is tightly regulated in time and space through a multitude of factors consisting of signaling molecules. Soluble N-ethylmaleimide-sensitive-factor attachment protein receptors (SNARE) are membrane proteins responsible for the intercellular trafficking of signals through endocytosis and exocytosis of vesicles. Altered expression of SN

2. Root perforations: a review of diagnosis, prognosis and materials
Abstract: Root perforation results in the communication between root canal walls and periodontal space (external tooth surface). It is commonly caused by an operative procedural accident or pathological alteration (such as extensive dental caries, and external or internal inflammatory root resorption). Different factors may predispose to this communication,

3. Biocompatibility of a new device of self-expandable covered and non-covered tracheal stent: comparative study in rats
PURPOSE: To investigate the compatibility of a new model of self-expandable tracheal stent in rats. METHODS: A new device of polyurethane covered and non - covered stent was placed in the trachea of Wistar rats. Animals were distributed in two groups: the polyurethane covered and non-covered group. Macroscopic parameters included position within the tracheal

4. Microbiological composition associated with vitamin D receptor gene polymorphism in chronic periodontitis
The aim of this cross-sectional study was to examine the relationship between the composition of the subgingival microbiota and the vitamin D receptor (VDR) gene polymorphism in Brazilian adults with chronic periodontitis. The clinical parameters of probing depth, clinical attachment level, bleeding on probing, plaque accumulation and suppuration were measur

5. Efeitos da ativina A, inibina A e folistatina Sobre células endometriais em um modelo de adesão e invasão peritoneal in vitro.
Objective: The aim of this study was to investigate whether activin A has an effect in the attachment and invasion of endometrial cells in a modeled peritoneum in vitro. Methods: Cultured endometrial stromal and epithelial cells were treated with activin A (concentration range 6.25 to 50 ng/ml) and with activin A 25 ng/ml alone or associated to inhibin A or

6. Modulação do processo de adesão célula-célula por prostaglandina E2 em células de adenocarcinoma de cólon humano / Modulation of the adhesion process cell-cell for prostaglandim E2 in cells of human colon adenocarcinoma.
A enzima ciclooxigenase-2 juntamente com a prostaglandina E2 (PGE2), tem sido descrito como potentes indutores da proliferação, migração e invasividade celular em câncer colo-retal. Neste trabalho nós investigamos os efeitos do tratamento da PGE2 no complexo juncional (CJ) de células epiteliais derivadas de adenocarcinoma de cólon humano, Caco-2. As

7. Modulation of Candida albicans attachment to human epithelial cells by bacteria and carbohydrates.
The effects of carbohydrates (mannose and dextrose). Escherichia coli 07KL. and Klebsiella pneumoniae on Candida albicans attachment to epithelial cells was studied. Dextrose had no effect on yeast attachment to epithelial cells. Conversely, mannose significantly decreased both yeast and piliated bacterial attachment (E. coli 07KL, heavily piliated K. pneumo

8. Attachment of Actinomyces naeslundii to human buccal epithelial cells.
A standardized assay was used to measure the attachment of Actinomyces naeslundii ATCC 12104 to washed human buccal epithelial cells. Treatment of the A. naeslundii cells with hyaluronidases, wheat germ lipase, protease, trypsin, heat, or sonic oscillation significantly reduced their ability to attach to epithelial cells. Treatment of the epithelial cells wi

9. Fibronectin Attachment Protein Is Necessary for Efficient Attachment and Invasion of Epithelial Cells by Mycobacterium avium subsp. paratuberculosis
Attachment and ingestion of Mycobacterium avium subsp. paratuberculosis by two epithelial cell lines were enhanced by soluble fibronectin (FN). Peptide blocking of the FN attachment protein (FAP-P) inhibited the internalization of M. avium subsp. paratuberculosis. Disruption of FAP-P expression significantly reduced attachment and ingestion of M. avium subsp

10. Actin accumulation at sites of attachment of indigenous apathogenic segmented filamentous bacteria to mouse ileal epithelial cells.
Selective attachment of indigenous, apathogenic, segmented filamentous bacteria to follicle-associated epithelia of terminal ileal Peyer's patches involves both the specialized M cells and normal enterocytes. A striking, highly localized cytoplasmic accumulation of polymerized actin, which resembles that associated with adherence of enteropathogenic Escheric

11. Use of gHgL for Attachment of Epstein-Barr Virus to Epithelial Cells Compromises Infection
Epstein-Barr virus (EBV) is a lymphotropic herpesvirus. However, access to B lymphocytes during primary infection may be facilitated by replication in mucosal epithelial cells. Attachment and penetration of EBV into these two cell types are fundamentally different. Both the distribution of receptors and the cellular origin of the virus impact the efficiency

12. Pneumocystis carinii attachment increases expression of fibronectin-binding integrins on cultured lung cells.
Pneumocystis carinii is an extracellular pathogen which requires attachment to alveolar epithelial cells for growth and replication. Previous studies have demonstrated that the extracellular matrix protein fibronectin (Fn) facilitates attachment of P. carinii to lung cells. This study addresses the role of cell surface Fn receptors (integrins) as mediators o
