To determine whether Bcl-2 could influence adult neurogenesis and prevent apoptosis of newborn neurons, we injected Bcl-2 expressing plasmid into the lateral ventricle of rat brain immediately following a 30-min occlusion of the middle cerebral artery (MCAO). We found that Bcl-2 increased neural progenitor cells (BrdU+-DCX+) in the ipsilateral striatum,(More)
Our previous experiments suggest that treatment with Bcl-2 increases proliferation and differentiation of neuronal progenitors induced by ischemic injury and ameliorates neurological functional deficits after stroke. However, in addition to its traditional anti-apoptotic effect, little is known about the concrete molecular modulation mechanism. In this(More)
In this study, we tested if caspase-3 inhibition decreased ischemia-induced Abeta elevation by reducing beta-secretase (BACE1) activity. Changes in caspase-3, Abeta and BACE1 levels were detected in rat striatum on different days after middle cerebral artery occlusion using immunostaining. We found that the positive labeled cells of activated caspase-3,(More)
Increasing lines of evidence indicate that estrogen acts as a neuroprotective agent through a nongenomic mechanism. We tested the hypothesis that 17beta-estradiol could rapidly attenuate glutamate-induced calcium (Ca2+) overload in rat primary hippocampal neurons via a membrane receptor-dependent mechanism. The bulk cytosolic intracellular Ca2+ level was(More)
Vascular endothelial growth factor (VEGF) protects neurons against ischemic injury. An overload of intracellular calcium ions (Ca(2+)) caused by the excessive release of glutamate is widely considered to be one of the molecular mechanisms of ischemic neuronal death. In the present study, we investigated whether VEGF could modulate the activity of Ca(2+)(More)
The antisense knockdown technique and confocal laser scanning microscopic analysis were used to elucidate vascular endothelial growth factor (VEGF) induction and its effect on DNA damage and repair in rat brain following a transient middle cerebral artery occlusion. Immunohistochemical study and in situ hybridization showed that the expression of VEGF and(More)
Ad hoc distributed simulation is an approach to predict future states of operational systems. It is based on embedding on-line simulations into a sensor network and adding communication and synchronization among the simulators. While prior work focused on this approach in the context of online management of transportation systems, this paper describes a(More)
Session Initiation Protocol (SIP) has been proposed for multimedia services and wide-area connectivity in smart home environments (SHEs). An important issue for SIP deployment in SHEs is network address translator (NAT) traversing. SIP and Real-time Transport Protocol (RTP) packets are delivered between an SHE (i.e., private IP network) and Internet (i.e.,(More)
