Ceramides, which are membrane sphingolipids and key mediators of cell-stress responses, are generated by a family of (dihydro) ceramide synthases (Lass1-6/CerS1-6). Here, we report that brain development features significant increases in sphingomyelin, sphingosine, and most ceramide species. In contrast, C(16:0)-ceramide was gradually reduced and CerS6 was(More)
Integrins govern cellular adhesion and transmit signals leading to activation of intracellular signaling pathways aimed to prevent apoptosis. Herein we report that attachment of oligodendrocytes (OLs) to fibronectin via alpha(v)beta(3) integrin receptors rendered the cells more resistant to apoptosis than the cells attached to laminin via alpha(6)beta(1)(More)
BACKGROUND Insecticide-treated bednets (ITNs) are effective in preventing malaria where vectors primarily bite indoors and late at night, but their effectiveness is uncertain where vectors bite outdoors and earlier in the evening. We studied the effectiveness of ITNs following a mass distribution in Haiti from May to September, 2012, where the Anopheles(More)
