Emerging evidence suggests that immune proteins regulate activity-dependent synapse formation in the central nervous system (CNS). Mice with mutations in class I major histocompatibility complex (MHCI) genes have incomplete eye-specific segregation of retinal ganglion cell (RGC) axon projections to the CNS. This effect has been attributed to causes that are(More)
Through transcriptional regulations, the BarH family of homeodomain proteins play essential roles in cell fate specification, cell differentiation, migration, and survival. Barhl2, a member of the Barh gene family, is expressed in retinal ganglion cells (RGCs), amacrine cells (ACs), and horizontal cells. Here, to investigate the role of Barhl2 in retinal(More)
Math5-null mutation results in the loss of retinal ganglion cells (RGCs) and in a concurrent increase of amacrine and cone cells. However, it remains unclear whether there is a cell fate switch of Math5-lineage cells in the absence of Math5 and whether MATH5 cell-autonomously regulates the differentiation of the above retinal neurons. Here, we performed a(More)
Neural networks have found profound success in the area of pattern recognition. The purpose of this paper is to classify automatically musical instrument sounds on the basis of a limited number of parameters. And this involves issues like feature extraction and development of classifier using the obtained features. As for feature extraction, a 5 second(More)
AIM To determine whether cysteinyl leukotriene receptor 1 (CysLT1 receptor) is involved in N-methyl-D-aspartate (NMDA)-induced excitotoxic injury in the mouse brain. METHODS Brain injury was induced by NMDA microinjection (50-150 nmol in 0.5 microL) into the cerebral cortex. The changes in CysLT1 receptor expression 24 h after NMDA injection and the(More)
In the dorsal spinal cord, distinct interneuron classes relay specific somatosensory information, such as touch, heat, and pain, from the periphery to higher brain centers via ipsilateral and contralateral axonal pathways. The transcriptional mechanisms by which dorsal interneurons choose between ipsilateral and contralateral projection fates are unknown.(More)
In this paper, the impact of process variation on soft error vulnerability for nanometer VLSI circuits is studied. Particle strike is modeled in SPICE as a current source connected to the node of interest. Qcritical offour kinds of circuits at different technology nodes is analyzed. Our simulation result shows that process variation can make Qcritical vary(More)
To explore the mechanism underlying antileukaemia effect of sodium valproate, the growth and survival of the K562 cell line were investigated. Global profiles of gene expression in K562 cells exposed to sodium valproate were assessed and validated. The differentially expressed genes identified were further used to query the connectivity map database to(More)
Neuronal populations display conspicuous variability in their size among individuals, but the genetic sources of this variation are largely undefined. We demonstrate a large and highly heritable variation in neuron number within the mouse retina, affecting a critical population of interneurons, the horizontal cells. Variation in the size of this population(More)
PURPOSE In the development of therapeutic vaccines against cancer, it is important to design strategies for antigen cross-presentation to stimulate cell-mediated immune responses against tumor antigens. METHODS We developed a polyethyleneimine (PEI)-based protein antigen delivery system to promote cross-presentation through the major histocompatibility(More)
