— The nearest neighbor (NN) technique is very simple, highly efficient and effective in the field of pattern recognition, text categorization, object recognition etc. Its simplicity is its main advantage, but the disadvantages can't be ignored even. The memory requirement and computation complexity also matter. Many techniques are developed to overcome(More)
Somatosensory evoked potentials were recorded in five normal women on percutaneous stimulation of the pudendal nerve. A consistent response was obtained over the scalp 2 cm behind the Cz electroencephalographic recording site. The latency of onset of this response had a mean value of 33 msec, and the mean latency of the first positive peak was 39.6 msec.(More)
BACKGROUND A primary concern after posterior lumbar spine arthrodesis is the potential for adjacent segment degeneration cephalad or caudad to the fusion segment. There is controversy regarding the subsequent degeneration of adjacent segments, and we are aware of no long-term studies that have analyzed both cephalad and caudad degeneration following(More)
With increasing efforts to develop and utilize mouse models of a variety of neuro-developmental diseases, there is an urgent need for sensitive neuroimaging methods that enable in vivo analysis of subtle alterations in brain anatomy and function in mice. Previous studies have shown that the brains of Fibroblast Growth Factor 17 null mutants (Fgf17(-/-))(More)
The dorsal nerve of the penis or clitoris, a branch of the pudendal nerve, was stimulated while averaged evoked responses over the spinal cord, sensory cortex, and bulbocavernosus muscle were recorded in a series of normal subjects. The morphologic features, peak latencies, and peripheral and central conduction times were compared with spinal and cortical(More)
While many studies have focused on modulating the immune response and enhancing axonal regeneration after spinal cord injury (SCI), there is limited work being performed on evaluating the role of glial scar in SCI. We sought to evaluate the effects of glial scar resection in contusion models and dorsal hemisection models of SCI. At 1-week postinjury, 2 mm(More)
We examined the roles of vitronectin and plasminogen activator inhibitor-1 (PAI-1) in neointima development. Neointima formation after carotid artery ligation or chemical injury was significantly greater in wild-type mice than in vitronectin-deficient (Vn(-/-)) mice. Vascular smooth muscle cell (VSMC) proliferation did not differ between groups, suggesting(More)
Mutant alleles of MYH9 encoding a class II non-muscle myosin heavy chain-A (NMMHC-IIA) have been linked to hereditary megathrombocytopenia with or without additional clinical features that include sensorineural deafness, cataracts, and nephritis. To assess its biological role in the affected targets, particularly the inner ear, we have generated and(More)
