Vibrotactile rendering is one of the most popular means for improving the user interface of a mobile device, but the availability of related perceptual data that can aid vibrotactile effect design is not currently sufficient. The present paper reports data from a series of psychophysical studies designed to fill this gap. In Experiment I, we measured the(More)
This study was performed to evaluate the static and dynamic magnetic resonance imaging (MRI) contrast enhancement pattern of progressive massive fibrosis (PMF) in coal workers' pneumoconiosis. Eighteen lesions in 12 patients were evaluated using a 1.5-T MR unit. T1-weighted FLASH images were obtained before and 0.5, 1, 2, 3, 4, 5, 7.5, 10, 12.5, and 15(More)
OBJECTIVE The purpose of this study was to determine the potential of CT for distinguishing tuberculous peritonitis from peritoneal carcinomatosis in 135 clinically or pathologically proven cases. MATERIALS AND METHODS Abdominal CT scans in 135 patients of tuberculous peritonitis (n = 42) and peritoneal carcinomatosis (n = 93) with documented omental,(More)
We reported previously that cofilin, an actin-binding protein, interacts with Na,K-ATPase and enhances its activity (Lee, K., Jung, J., Kim, M., and Guidotti, G. (2001) Biochem. J. 353, 377-385). To understand the nature of this interaction and the role of cofilin in the regulation of Na,K-ATPase activity, we searched for cofilin-binding proteins in the rat(More)
Translationally controlled tumor protein (TCTP) is believed to be involved in a variety of inflammatory processes: secretion of histamine and cytokines such as IL-4, IL-8, IL-13, and granulocyte/macrophage colony-stimulating factor; chemoattraction for eosinophils; augmentation of B cell proliferation; and immunoglobulin production, thereby potentially(More)
We reported previously that translationally controlled tumor protein (TCTP) is a cytoplasmic repressor of Na,K-ATPase in HeLa cells. In the current study, we showed that TCTP overexpression using adenovirus as vehicle, induced partial inhibition of Na,K-ATPase; phosphorylation of EGFR tyrosine residues 845, 992,1068, and 1148; activation of Ras/Raf/ERK(More)
We previously reported that phosphorylated cofilin-triosephosphate isomerase (TPI) complex interacts with Na,K-ATPase and enhances the pump activity through the phosphorylation of cofilin via Rho-mediated signaling pathway. In this study, we tested the hypothesis that the dephosphorylation of cofilin may be induced through Na,K-ATPase inhibition by ouabain.(More)
