Adhesion molecule upregulation occurs in inflammatory myopathies, and is one of the myriad functions of tumor necrosis factor-alpha (TNF-alpha). TNF-alpha acts via two different receptors of 55 (TNF-R55) and 75 kD (TNF-R75). We immunolocalized TNF-alpha and its receptors in polymyositis, inclusion body myositis and dermatomyositis. In each myopathy,(More)
Stickler syndrome is an autosomal dominant connective tissue disorder caused by mutations in different collagen genes. The aim of our study was to define more precisely the phenotype and genotype of Stickler syndrome type 1 by investigating a large series of patients with a heterozygous mutation in COL2A1. In 188 probands with the clinical diagnosis of(More)
We previously established that the trefoil peptides (TFFs) pS2, spasmolytic polypeptide, and intestinal trefoil factor are involved in cellular scattering and invasion in kidney and colonic cancer cells. Using the chorioallantoic membrane (CAM) assay and the formation of tube-like structures by human umbilical vein endothelial cells (HUVEC) plated on the(More)
BACKGROUND Previous reports on endoscopic retrograde brush cytology (ERBC) of bile ducts and of the main pancreatic duct have reached widely varying sensitivity levels of 33 up to 85%. AIMS To report our experience with ERBC in a series of biliary strictures (n = 98) and pancreatic duct strictures (n = 8). For the purpose of our study, that was mainly(More)
In total, 226 individuals from the community were investigated for faecal carriage of Acinetobacter spp. by broth enrichment culture, followed by growth on blood agar and/or Leeds Acinetobacter Medium (LAM). Acinetobacter baumannii was isolated on both LAM and blood agar from one of 100 specimens in the UK and one of 126 specimens in The Netherlands. The(More)
E(pithelial)-cadherin and N(eural)-cadherin are transmembrane cell-cell adhesion molecules, belonging to the subfamily of classical cadherins. The expression of E- and N-cadherin is spatiotemporally regulated and associated with a variety of normal morphogenetic events. The expression of E- and N- cadherin is also involved in carcinogenesis. E-cadherin(More)
PURPOSE To investigate whether trypan blue has a toxic effect on cultured retinal pigment epithelial (retinal pigment epithelium) cells. DESIGN Experimental study with a direct live/dead cell staining technique using fluorescent dyes. METHODS Cultured human retinal pigment epithelium cells were exposed for 5 minutes to various concentrations of trypan(More)
A 59-year-old man was admitted to the hospital for dysphagia and fever. Esophagogram and upper gastrointestinal endoscopy revealed a polypoid mass in the midesophagus. Subtotal esophagectomy, cervical esophagogastrostomy, and lymph node dissection were performed. The histological diagnosis of the tumor was malignant fibrous histiocytoma. An area of severe(More)
