The present electron microscopic study of a spontaneous mammary tumor (diagnosed histologically as adenocarcinoma) of collared lemming was undertaken in search for the possible presence of particles resembling oncogenic RNA virus particles. The study has demonstrated the presence of a large number of characteristic virus-like particles. The virus-like particles were similar to the ham ster type...

This paper describes the application of a new multi-criteria decision making (MCDM) technique called fuzzy outranking to map prospectivity for porphyry Cu Mo deposits. Various raster-based evidential layers involving geological, geophysical, and geochemical geo-data sets are integrated for mineral prospectivity mapping (MPM). In a case study, 13 layers of the Now Chun deposit located in the Ker...

Submucosal tumor (SMT) is a disease that is commonly discovered during endoscopic examination. With advances in endoscopic ultrasonography (EUS) technology, this technique has become the primary screening method for the diagnosis of upper gastrointestinal SMTs. The present study summarized the clinical data of patients who were examined and diagnosed with upper gastrointestinal SMTs by EUS, und...

THE ~aj~r bame~ in clinical transplantation has been the hmltatlon ot donor organs. I Xenotransplantation has been considered an alternative source of organs, however strong immunolOgiC barriers are thought to make this option impractical. The immunosuppressant FK 506 has been shown to be several hundred times more potent than cyclosporine (CyA)2.) and it is capable of suppressing antibody prod...

Abstract Objectives Gastric glomus tumor (GGT) is a rare mesenchymal tumor, mostly located in the gastric antrum region, and occasionally displays malignant behavior. Due to lack of typical endoscopic or clinical features that distinguish GGT from other submucosal tumors, diagnosis based primarily on postoperative histopathological immunohistochemical findings. The first-line treatment either l...
