Glutamate transporters are involved in the maintenance of synaptic glutamate concentrations. Because of its potential neurotoxicity, clearance of glutamate from the synaptic cleft may be critical for neuronal survival. Inhibition of glutamate uptake from the synapse has been implicated in several neurodegenerative disorders. In particular, glutamate uptake(More)
Neuron death and neuron degeneration occur in the CNS during the course of aging. Although multiple cellular alterations transpire during the aging process, those that mediate age-associated neuron death have not been identified. Recent evidence implicates oxidative stress as a possible means of neuron death and neuron degeneration during aging. In the(More)
Numerous studies indicate a role for oxidative stress in the neuronal degeneration and cell death that occur during ischemia-reperfusion injury. Recent data suggest that inhibition of the proteasome may be a means by which oxidative stress mediates neuronal cell death. In the current study, the authors demonstrate that there is a time-dependent decrease in(More)
It was recently reported that in one of the adult neurogenetic zones, the subventricular zone (SVZ), astrocyte-like cells release glutamate upon intracellular Ca2+ increases. However, the signals that control Ca2+ activity and glutamate release from SVZ astrocytes are not known. Here, we examined whether prostaglandin E2 (PGE2), which induces glutamate(More)
The autoxidation and enzymatic catabolism of dopamine results in the generation of reactive oxygen species (ROS), which may possibly contribute to oxidative stress in multiple neurodegenerative disorders. Recent studies indicate that proteasome inhibition occurs in numerous neurodegenerative conditions, possibly as the result of oxidative stress, although(More)
Failure analysis (FA) and diagnosis of memory cores plays a key role in system-on-chip (SOC) product development and yield ramp-up. Conventional FA based on bitmaps and the experiences of the FA engineer is time consuming and error prone. The increasing time-to-volume pressure on semiconductor products calls for new development flow that enables the product(More)
BACKGROUND The report from the Institute of Medicine, To Err Is Human: Building a Safer Health System in 1999 drew a special attention towards preventable medical errors and patient safety. The American Reinvestment and Recovery Act of 2009 and federal criteria of 'Meaningful use' stage 1 mandated e-prescribing to be used by eligible providers in order to(More)
