A smart Human-Computer Interface(HCI)replacing conventional mouse interface is proposed.The interface is able to control cursor and command action with only hand.Four finger motions(left click,right click,hold,drag)are used to command the interface.Also the authors materialize cursor movement control using image processing.The measure what they use for inference is entropy of Electromyogram(EMG)signal,Gaussian modeling and maximum likelihood estimation.In image processing for cursor control,they use color recognition to get the center point of finger tip from marker,and map the point onto cursor.Accuracy of finger movement inference is over 95% and cursor control works naturally without delay.They materialize whole system to check its performance and utility. 相似文献

The lipid content and fatty acid profile in soft tissue of the green-lipped mussel Perna viridis, a widely distributed tropical and subtropical bivalve species, were investigated. The total and neutral lipid contents were 6.17 ± 0.71 and 2.71 ± 0.42 mg per 100 mg dw, respectively. The content of docosahexaenoic acid (DHA, C22:6n-3) was 24.38 ± 2.50 mg/g dw whereas eicosapentaenoic acid (EPA, C20:5n-3) was present at 12.29 ± 2.12 mg/g dw. These two fatty acids were also at the top high percentage among all the fatty acids, with 38.06 ± 0.86% and 17.89 ± 1.24% (w/w) in total lipids and 34.64 ± 2.74% and 20.33 ± 1.05% (w/w) in neutral lipids, respectively. Therefore, green-lipped mussel is a rich source of DHA and EPA, the two n-3 polyunsaturated fatty acids that are beneficial to human health and nutrition. 相似文献

Background: Activated hepatic stellate cells (HSCs) are closely involved in the initiation, perpetuation, and
resolution of liver fibrosis. Pro-inflammatory cytokine levels are positively correlated with the transition from liver
injury to fibrogenesis and contribute to HSC pathophysiology in liver fibrosis. Methods: In this study, we investigated
the effect of the pro-inflammatory cytokine interleukin (IL)-1β on the proliferation and signaling pathways involved
in fibrogenesis in LX-2 cells, an HSC cell line, using western blotting and cell proliferation assays. Results: IL-1β
increased the proliferation rate and α-smooth muscle actin (SMA) expression of LX-2 cells in a dose-dependent
manner. Within 1 h after IL-1β treatment, c-Jun N-terminal kinase (JNK), p38, and nuclear factor-κB (NF-κB)
signaling was activated in LX-2 cells. Subsequently, protein kinase B (AKT) phosphorylation and an increase in α-
SMA expression were observed in LX-2 cells. Each inhibitor of JNK, p38, or NF-κB decreased cell proliferation, AKT
phosphorylation, and α-SMA expression in IL-1β-treated LX-2 cells. Conclusion: These results indicate that JNK,
p38, and NF-κB signals converge at AKT phosphorylation, leading to LX-2 activation by IL-1β. Therefore, the AKT
signaling pathway can be used as a target for alleviating liver fibrosis by the inflammatory cytokine IL-1β. 相似文献
