<P>Hepatocellular carcinoma (HCC) is one of the most frequent malignant tumors in the world. The only serological marker widely used for the diagnosis of HCC is alpha-fetoprotein (AFP). Despite that AFP is widely used for the diagnosis of HCC, it has a limit as a serological marker due to its low sensitivity and specificity. The human cervical cancer proto-oncogene 1 (HCCR-1) was previously reported as a new biomarker for HCC. To further evaluate the HCCR-1 as a biomarker for HCC, we conducted the prospective cohort study. We evaluated the significance of simultaneous measurement of 2 tumor markers in the diagnosis of HCC in China, Japan and Korea. Two markers for HCC, AFP and HCCR-1, were measured in the sera obtained from 1,338 patients at the time of initial diagnosis of HCC. Of the 1338 HCC patients, 616 (46%) and 686 (51.3%) were sero-positive for AFP and HCCR-1, respectively. The positive rate for HCC was increased up to 74.1% in combined use of AFP and HCCR-1. Many cases (54%) for AFP-negative HCC were positive for HCCR-1 and vice versa. More importantly, the diagnostic rate for small HCC (< 2 cm) was significantly improved in the combined analysis of AFP and HCCR-1 to 56.9% although it was only 40.1% and 23.4% in the single analysis of HCCR-1 and AFP, respectively. Our result suggests that the HCCR-1 could be an useful biomarker for HCC while the diagnostic rate could be significantly improved in the combined use of HCCR-1 and AFP.</P>
Large Displacement Optical Flow with Adaptive Feature Match
Xiaoping Zhang,Guoxin Li 보안공학연구지원센터(IJSIP) 2014 International Journal of Signal Processing, Image Vol.7 No.6
This paper presents an accurate large displacement optical flow estimation approach by adaptively integrate the local feature match. Despite coarse-to-fine warping approach can handle large displacement optical flow; however, there is inherent limit for small object with large motion. And recently integration of feature match to the variational framework has relaxed the limit, but raised another problem of ambiguous feature matching due to poor feature descriptor. Address the aforementioned problem, in this paper we propose an adaptive integration approach of local feature match. The essence is that we only keep the robust feature and remove those unstable features (e.g, textureless region) to improve the flow accuracy. The adaptive approach substantially decreases the computational cost by remove uncertain features and leads to more robust performance by excluding unreliable matches. We qualitatively and quantitatively compared to the conventional flow methods on Middlebury and Sintel benchmark and show that we achieve more accurate and promising results.

The Arabidopsis gene AVP1 encodes an H?-pyrophosphatase that functions as a proton pump at thevacuolar membranes, generating a proton gradient acrossvacuolar membranes, which serves as the driving force formany secondary transporters on vacuolar membranes suchas Na?/H?-antiporters. Overexpression of AVP1 couldimprove drought tolerance and salt tolerance in transgenicplants, suggesting a possible way in improving drought andsalt tolerance in crops. The AVP1 was therefore introducedinto peanut by Agrobacterium-mediated transformation. Analysis of AVP1-expressing peanut indicated that AVP1-overexpression in peanut could improve both droughtand salt tolerance in greenhouse and growth chamberconditions, as AVP1-overexpressing peanuts producedmore biomass and maintained higher photosynthetic ratesunder both drought and salt conditions. In the field, AVP1-overexpressing peanuts also outperformed wild-type plantsby having higher photosynthetic rates and producing higheryields under low irrigation conditions.

The Arabidopsis gene AVP1 encodes an $H^+$-pyrophosphatase that functions as a proton pump at the vacuolar membranes, generating a proton gradient across vacuolar membranes, which serves as the driving force for many secondary transporters on vacuolar membranes such as $Na^+/H^+$-antiporters. Overexpression of AVP1 could improve drought tolerance and salt tolerance in transgenic plants, suggesting a possible way in improving drought and salt tolerance in crops. The AVP1 was therefore introduced into peanut by Agrobacterium-mediated transformation.

IMPACTS OF RELATIONSHIP VALUE ON LOYALTY OF ONLINE GROUP-BUYING CUSTOMER IN CHINA

Impacts of Relationship value on Loyalty of Online Group-Buying Customer in China With the development of e-commerce industry, online group-buying pattern has been one of the most popular online shopping patterns in China. Although the online group-buying platform has a large number of consumers, the consumer loyalty to specific online group-buying platform is low. For this phenomenon, scholars usually studied from the perspective of factors which influenced consumer behavior intentions. However, few studies focus on the component and measuring of relational benefits in the process of group-buying. Based on the perspective of consumers, this paper studied the relational benefits between consumers and online group-buying platform, and the perceived benefits of consumers who are in different relationship life cycle.This paper used SPSS to test the reliability and validity of data and carried some discussions about research model through factor analysis and regression analysis. The results indicated that relational benefits were significantly related to customer loyalty, that relationship quality and relationship life cycle was considered as mediator and moderator, respectively. Further, we made some management recommendations for operators in the online group-buying platform.
