It has been postulated that chronic administration of antidepressant drugs induces delayed structural and molecular adaptations at glutamatergic forebrain synapses that might underlie mood improvement. To gain further insight into these changes in the cerebral cortex, rats were treated with fluoxetine (flx) for 4 weeks. These animals showed decreased(More)
Human neural stem cells (HNSCs) may serve as a cellular vehicle for molecular therapies as well as for cell replacement in the human CNS. The survival, integration, and differentiation of HNSC.100, a multipotent cell line of HNSCs (A. Villa et al. (2000), Exp. Neurol. 161, 67-84), conditionally perpetuated by genetic and epigenetic means, was investigated(More)
Neural stem cell lines represent a homogeneous source of cells for genetic, developmental, and gene transfer and repair studies in the nervous system. Since both gene transfer of neurotrophic factors and cell replacement strategies are of immediate interest for therapeutical purposes, we have generated BDNF-secreting neural stem cell lines and investigated(More)
Multilayer membranes for the treatment of oily waters have been prepared from ceramic materials. Alumina and cordierite supports have been prepared as well as ␣-Al 2 O 3 intermediate layers. ␥-Al 2 O 3 top layers with very high porosities were prepared by the sol–gel method and a detailed study has been performed because of the importance of this layer in(More)
Reverse-Time Migration (RTM) is a state-of-the-art technique in seismic acoustic imaging, because of the quality and integrity of the images it provides. Oil and gas companies trust RTM with crucial decisions on multi-million-dollar drilling investments. But RTM requires vastly more computational power than its predecessors, and this has somewhat hindered(More)
