BACKGROUND The most suitable mechanical endoscopic hemostasis for a bleeding Dieulafoy's lesion (DL) is not yet well established. OBJECTIVE To compare the hemostatic efficacy and clinical outcome of endoscopic hemoclip placement (EHP) and endoscopic band ligation (EBL). DESIGN Retrospective, single-center study. SETTING A tertiary-care referral university hospital. PATIENTS Sixty-six pa...
PURPOSE To determine the safety, tolerability and maximum tolerated dose (MTD) of addition of erlotinib to bevacizumab and capecitabine-based definitive chemoradiation (CRT) in unresectable pancreatic cancer. METHODS Seventeen patients with CT-staged, biopsy-proven unresectable pancreatic cancer were enrolled between 3/2008 and 10/2010. Prior chemotherapy was permitted. Two patients each were...
Differential centrifugation of several plant extracts indicates that the majority of the hydroperoxide isomerase activity is present in the cytoplasm of the cell. However, lesser amounts of isomerase activity were found in the mitochondrial and microsomal fractions of sunflower seedlings. Sucrose density gradient centrifugation of extracts from sunflower, watermelon, and flax seedlings and from...
Fuzzy Description Logics (DLs) are logics that allow to deal with vague structured knowledge. Although a relatively important amount of work has been carried out in the last years concerning the use of fuzzy DLs as ontology languages, the problem of automatically managing fuzzy ontologies has received very little attention so far. We report here our preliminary investigation on this issue by de...
