Mechanisms of haematopoietic and cardiac patterning remain poorly understood. Here we show that the BMP and Wnt signalling pathways are integrated in an endoglin (Eng)-dependent manner in cardiac and haematopoietic lineage specification. Eng is expressed in early mesoderm and marks both haematopoietic and cardiac progenitors. In the absence of Eng, yolk sacs inappropriately express the cardiac ...

During embryonic development, hematopoietic cells develop by a process of endothelial-to hematopoietic transition of a specialized population of endothelial cells. These hemogenic endothelium (HE) cells in turn develop from a primitive population of FLK1 mesodermal cells. Endoglin (ENG) is an accessory TGF-β receptor that is enriched on the surface of endothelial and hematopoietic stem cells an...

Eight species of the family Arrhopalitidae Stach, 1956 are listed from the Republic of Moldova. A new species, Arrhopalites prutensis sp. nov. is described. It belongs to the diversus group of species with 3, 2, 1, 1 anterior setae on dens, possesses neosminthuroid seta on the furca base region-a character rarely noted for the family. The new species is closely related to A. baccettii Dallai, 1...

Today, the accumulated volume of data traffic is on the verge of surpassing the accumulated volume of voice traffic in all public networks. Given the growth in the areas of wireless voice and data, we see that the combination of mobile and Internet communication constitutes the driving force behind third-generation wireless systems, which promise to support at least 144 kbit/s (384 kbit/s) in a...
