Recent studies have discovered the existence of water-channel molecules, the so called aquaporins (AQP) presumably involved in active, ATP dependent water transport between the intracellular and extracellular compartments. Both genetic and protein sequences and structures of the AQPs are known and crystallographic analyses of some members of the AQP family(More)
For increased speed in developing gigaword language resources for medium resource density languages we integrated several FOSS tools in the HUN* toolkit. While the speed and efficiency of the resulting pipeline has surpassed our expectations, our experience in developing LDC-style resource packages for Uzbek and Kurdish makes clear that neither the data(More)
Malignant gliomas are among the deadliest primary brain tumors. Despite multimodal therapy and advances in chemotherapy, imaging, surgical and radiation techniques, these tumors remain virtually incurable. Glioma stem cells may be responsible for resistance to traditional therapies and tumor recurrence. Therefore, elimination of glioma stem cells may be(More)
Human brain trypsin(ogen) 4-like (HT-4) immunoreactivity was localized in glial cells of human cerebral cortex and spinal cord. After a short post mortem delay (two hours), cortical and spinal cord regions were dissected, frozen or immersed into a fixative solution. Sections of 10 and 50 microm thickness were cut and immunostained by antibodies raised(More)
Tunneling nanotubes (TNTs) are long intercellular connecting structures providing a special transport route between two neighboring cells. To date TNTs have been reported in different cell types including immune cells such as T-, NK, dendritic cells, or macrophages. Here we report that mature, but not immature, B cells spontaneously form extensive TNT(More)
The unusual physical properties and formation conditions attributed to h-, i-, m-, and n-nanodiamond polymorphs has resulted in their receiving much attention in the materials and planetary science literature. Their identification is based on diffraction features that are absent in ordinary cubic (c-) diamond (space group: Fd-3m). We show, using(More)
