Brush cells occur in the epithelium of the small intestine and in various other epithelia of endodermal origin. Ultrastructural and histochemical characteristics suggest that they represent sensory cells. Because the apical membrane of brush cells might be involved in and specialized for (chemo-)receptive functions, we investigated the composition of the(More)
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)
Modern frequency division duplex radio frequency transceivers experience transmitter-to-receiver leakage due to the limited isolation of the duplexer. In Long Term Evolution-Advanced (LTE-A) carrier aggregation receivers the coupling between the local oscillators creates harmonics on the chip which can lead to the downconversion of this leakage signal to(More)
