Brush cells are specialised epithelial cells that are assumed to represent chemoreceptors of the digestive tract. They comprise a small population of the epithelial cells lining the intestine, possess a unique ultrastructure and, in many aspects, resemble the receptor cells of taste buds. To characterise glycoconjugates possibly involved in a sensory(More)
Decreasing sizes and a static decline in production costs are fostering the use of RFID tags and sensors in cross-company logistics networks. Additionally, the EPCIS specification comprises interface standards for capturing and querying RFID based event data and storing it in a standardized data format. This contribution examines the potential of the given(More)
BACKGROUND Vascular endothelial growth factor (VEGF)-A and angiopoietin (Ang)-1 and Ang-2 are key factors in angiogenic signaling. In this study the expression of these factors was identified in cartilage tumors. As interleukin (IL)-1beta has been found to be an indispensable factor in angiogenic signaling, we further analyzed the effect of IL-1beta on the(More)
Angiogenesis is characteristic of cartilage tumors, not of normal cartilage tissue. In addition to our previous report on differential expression of proangiogenic vascular endothelial growth factor A (VEGF-A) in cartilage tumors, we analyzed the expression of a disintegrin and metalloproteinase with thrombospondin motifs 1 (ADAMTS1), which has been(More)
We operationalize scientific output in a region by means of the number of articles (as in the SciSearch database) per year and technology output by means of the number of patent applications (as in the database of the European Patent Office) per priority year. All informetric analyses were done using the DIALOG online-system. The main research questions are(More)
 Low-power bright field photomicrographs often suffer from insufficient sharpness, uneven illumination, and colour hues. Using a film scanner, commercially available and designed for digitizing 35-mm transparencies, we directly scanned microscopic slides that carried dye-labelled and stained sections. The digital images covered a field of up to 24×36 mm and(More)
