In natural language relationships between entities can asserted within a single sentence or over many sentences in a document. Many information extraction systems are constrained to extracting binary relations that are asserted within a single sentence (single-sentence relations) and this limits the proportion of relations they can extract since those expressed across multiple sentences (inter-...

Primary signet-ring cell/histiocytoid carcinomas of the eyelid are extremely rare tumors considered to originate from sweat glands. Here, we report the case of a 72-year-old man diagnosed with primary signet-ring cell/histiocytoid carcinoma of the eyelid and present immunohistochemical analyses of the eyelid apocrine gland (Moll gland) and apocrine and eccrine sweat glands of perineum and axill...

INTRODUCTION The presence of MUC5AC (M1 antigen) and MUC6 have previously been found in ovarian mucinous cyst. We characterized the mucins in the crude mucus and tissue of a mature ovarian teratoma in an 8 year old girl. MATERIALS AND METHODS Mucins were purified from crude mucus by density gradient ultra-centrifugation in CsCl and analysed by gel-filtration and SDS-PAGE analysis. Mucin ident...

UNLABELLED Highly glycosylated apomucins are important to maintain the viscoelastic properties of the mucus. Changes in their expression are frequently associated with inflammatory and neoplastic conditions. We analyzed the expression of apomucins in normal respiratory tract (n = 8) and compared it with distal, peritumoral, and tumoral epithelia from patients with squamous cell carcinoma (n = 2...

PURPOSE Gastric and intestinal phenotypic cell markers are expressed in gastric carcinomas, irrespective of their histologic type. In the present study, we determined the clinicopathologic significance of phenotypic marker expression in early-stage gastric differentiated-type tumors and the association between marker expression and genetic alterations. EXPERIMENTAL DESIGN Phenotypic marker ex...

BACKGROUND Patients with Barrett's oesophagus (BO) are at risk of oesophageal adenocarcinoma. Because the pattern of mucosal mucins changes during neoplastic progression, it may serve as a marker of intraepithelial neoplasia. AIMS To determine the expression pattern of mucins in neoplastic BO epithelium (high grade dysplasia) and correlate it with the expression of apoptosis markers Bax and B...

This paper proposes a new approach for coreference resolution which uses the Bell tree to represent the search space and casts the coreference resolution problem as finding the best path from the root of the Bell tree to the leaf nodes. A Maximum Entropy model is used to rank these paths. The coreference performance on the 2002 and 2003 Automatic Content Extraction (ACE) data will be reported. ...
