Abstract

Today, the discovery and sharing of geospatial information over the Web presents some difficulties which have not yet been solved. News distribution through website content was simplified by the use of Really Simple Syndication (RSS) and Atom syndication formats. This paper exposes an extension of Atom to redistribute references to geospatial information in a Spatial Data Infrastructure distributed environment. A geospatial client can save the status of the application and share this status with other users that need to deal with the same information and use different client vendor products in an interoperable way. The extensibility of the Atom format was essential to define a format that could be used in RSS enabled web browser, Mass Market map viewers and emerging geospatial enable integrated clients that support Open Geospatial Consortium (OGC) services. The status exchange between a web client application and Geographic Information System desktop solution is demonstrated. [ABSTRACT FROM AUTHOR]

Abstract

A case of cardiac myxoma with glandular differentiation is reported. The patient did not have elements of the Carney triad or syndrome. The tumor was mainly composed of characteristic stellate cells in a focally collagenized, myxoid stroma, along with aggregates of glandular-forming epithelial cells, with mucin-containing intra- and intercellular lumina. Ultrastructurally, these gland spaces displayed short, straight microvilli and junctional complexes. The epithelial cells were positive for cytokeratin 7 and negative for cytokeratin 20. Calretinin was positive in the stellate cells and negative in the epithelial component. The potential origin from pluripotent mesenchymal cells or from seeded stem cells is hypothesized for glandular differentiation in myxomas. Further studies are required to unravel the relationship between stellate cells and the diverse heterologous components reported in these tumors. [ABSTRACT FROM AUTHOR]
