  • Researchers have shown the negative compatibility effect (NCE) consistently using arrows. However, they provided inconsistent interpretations about the reason why the NCE happens. The purpose of the present study is to test the factors suggested to be critical for the NCE including automatic inhibition, updated information and top-down control. Presented with arrays of masked prime and targets composed of colored double-headed arrows, participants demonstrated invulnerable NCE on the basis of direction of arrows in the judgment of direction with corresponding hands (Experiment 1), with reverse-mapping hands (Experiment 2) and even in the color-judgment task (Experiment 3). These results imply that the main sources of NCE might be perceptual dominance and inherent properties of stimuli and responses; this contrasts with previously proposed explanations.

  • Nattokinase (NK, E.C. 3.4.21.62) is a serine protease produced by Bacillus subtilis natto that shows promise for the treatment of thrombotic disease. In this study, we assessed the effects of NK on the development of hepatocellular carcinoma (HCC), a principal malignancy of the liver that causes morbidity and mortality worldwide. Crude extracts of NK (NCE) were isolated from fermentation medium by centrifugation and separated into three fractions (<10 K, 100~30 K and >30K). Orthotopic HCC mouse models were established and NCE was administered by oral gavage. H&E staining was performed to examine the pathology of HCC livers. Immunohistochemistry and immunofluorescence were used to evaluate FOXM1, CD31, CD44 and vimentin expression in the liver. Compared to PBS groups, NCE increased the survival rates of HCC-bearing mice to 31% and decreased ascites. Low-intensity ultrasound imaging showed that the hypoechoic mass area was lower in NCE-treated mice and that tumor growth significantly decreased. IHC staining showed that the expression of FOXM1 was inhibited by NCE treatment. Immunofluorescence results revealed lower levels of CD31, CD44 and vimentin in the NCE groups. Taken together, these data demonstrate that NCE from Bacillus subtilis natto improves survival and inhibits tumor growth in HCC mice.

  • Recently several hospitals have established a new nursing position so called, 'the nurse in charge of education (NCE).' The job description of NCE is to give a detail explanation on examination or test introduced to patients or a guide for those who are not familiar to hospital facilities at the out-patients level. The motivation of NCE position is the quality improvement in patient education on the sophisticated procedures or the follow up care for medical purposes to improve their compliances, as well in delivering services for outpatients or visitors in more informative and efficient way. The application of NCEA has been turned out positive and effective in patient satisfaction and unit management. However, special attention is brought to the scope and depth of the contents of education delivered by NCE which might overlap with the duty of physicians by the Medical Act. It is needed to clarify the role and job description of NCE in the context of Medical Act. The engagement of NCE to the Advanced Nursing Practitioner (ANP) is one of the possible solutions for a duty charge on patient education since ANP is a legislatively official position with higher license of RN at master level. Further discussion is needed to elaborate and arrange the details on the scope and content of patent education among health science professionals including RN, ANP and physicians.

  • Nash Cournot Equilibrium (NCE) has been widely used in a competitive electricity market to analyze generation firms' strategic production quantities. Congestion on a transmission network may lead to a mixed strategy NCE. Mixed strategy is complicated to understand, difficult to compute, and hard to implement in practical market. However, Stackelberg model based equilibrium does not have any mixed strategy, even under congestion in a transmission line. A guide to understanding mixed strategy equilibrium is given by analyzing a cycling phenomenon in the players' best choices. This paper connects the concept of leader-follower in Stackelberg model with relations between generation firms on both sides of the congested line. From the viewpoint of social welfare, the surplus analysis is presented for comparison between the NCE and the Stackelberg equilibrium (SE).

  • Magnetic resonance angiography (MRA) plays an important role in accurate diagnosis and appropriate treatment planning for patients with arterial disease. Contrast-enhanced (CE) MRA is fast and robust, offering hemodynamic information of arterial flow, but involves the risk of a side effect called nephrogenic systemic fibrosis. Various non-contrast-enhanced (NCE) MRA techniques have been developed by utilizing the fact that arterial blood is moving fast compared to background tissues. NCE MRA is completely free of any safety issues, but has different drawbacks for various approaches. This review article describes basic principles of CE and NCE MRA techniques with a focus on how to generate angiographic image contrast from a pulse sequence perspective. Advantages, pitfalls, and key applications are also discussed for each MRA method.

  • We propose integrating random network coding with the Enhanced On-Demand Multicast Routing Protocol (E-ODMRP). With the Network Coded E-ODMRP (NCE-ODMRP), we present a framework that enables a seamless integration of random linear network coding with conventional ad hoc multicast protocols for enhanced reliability. Simulation results show that the NCE-ODMRP achieves a nearly perfect packet delivery ratio while keeping the route maintenance overhead low to a degree similar to that of the E-ODMRP.

  • Amid global economic crisis and skyrocketing oil prices, container shipping companies have raised a sustained series of efforts to reduce vessel operating costs. Under these circumstances, the Grand Alliance has decided to install the dedicated feeder instead of additional vessels in the CCX(Central China Express) and the NCE(North China Express) route. In other words, a vessel in a trunk route is transshiped by a dedicated feeder vessel in Busan port that is a transshipment port, rather than calling at Northen China port. In this study, the actual operating data of Grand Alliance container services were analyzed to determine the economic effect of transshipment through a dedicated feeder service. In this way, the Grand Alliance are saving vessel operating expenses in 'NCE' and 'CCX' routes, making the slow steaming of vessels possible in these trunk routes.

  • Colloidal $^{32}P$ chromic phosphate is used to prevent hepatic metastasis from colorectal cancer. It is speculated that the intravenous injection of colloidal $^{32}P$ chromic phosphate can cause genotoxicity. To evaluate the genotoxicity of intravenously injected colloidal $^{32}P$ chromic phosphate, authors performed a micronuclei test in mice bone marrow. Mice (ICR strain, $25\sim30g$) were divided to 4 groups: control, group 1 (19.166 KBq/g, usual therapeutic dose in human), group 2 (191.66 KBq/g), and group 3 (1916.6 KBq/g). Five mice of each group were sacrificed at days 1, 2, 3, 5, 7 and 14. Bone marrow were smeared and stained with Wright-Giemsa method. One thousand polychromatic erythrocytes (PCE) and normochromatic erythrocytes (NCE) were counted under the light microscope, and the number of micronucleated PCEs and NCEs were recorded. The frequency of micronuclei in PCE and NCE in the control group was $0.3{\pm}0.06%\;and\;0.45{\pm}0.10%$, respectively. At group 1, frequency of micronuclei is not different from the control. However, frequencies of micronuclei in PCE at groups 2 and 3 were significantly increased from day 1 and persisted to day 14. The frequency of micronuclei in NCE was increased only at group 3. In conclusion, the frequency of micronuclei increases as the dose of colloidal $^{32}P$chromic phosphate increases, while micronuclei was not induced at the usual therapeutic dose. And the frequency of micronuclei persistently elevated for 14 days in the cases of higer doses.
