Xing-Yao Chen,Yao-Xiong Huang,Wen-jing Liu,Zhi-jian Yuan 한국물리학회 2007 Current Applied Physics Vol.7 No.s1

ditions were studied as a function of cell age. The young and old cells were separated from fresh rabbit blood by using Percoll densitygradients. A novel multi-dimensional microscope was employed to perform real-time, non-invasivein situmeasurements on the mem-brane bending elastic modulus and the cell shape and size. A phase-analysis micro-electrophoresis laser scattering technique was usedto measure the surface charge density. The results show that the membrane Zeta potential of red blood cells is reduced when they become.

The purpose of this paper is to analyze the characteristics of the “post-80`s generation” in Northeast region in China. The “post-80” generation means the new cohort of the Chinese who were born between 1980 and 1989. The “post-80`s generation” is generally considered as a spoiled generation without maturity, humility and responsibility. They are also regarded as individualistic risk takers. Since China`s reform and opening up, the “post-80`s generation” have been benefited from the expansion of higher education enrollment, as the product of “the one child” policy. This study attempts to analyze the characteristics of the “post-80`s generation. In comparison with the coastal south region, the northeastern region owes a more distinguishing feature of the planned economy and the strong legacy from socialism. Shenyang and Yingkou were chosen as the study areas, and with qualitative data, this study tries to offer a new understanding of this generation.

임성요(Xing Yao Ren),오세조(Sejo Oh),성민(Min Sung) 한국유통학회 2006 流通硏究 Vol.11 No.4

이 연구는 중국 화장품 시장에서 외국계 공급업체와 현지 소매업체간 관계의 질 변수인 신뢰와 결속에 영향을 미치는 선행변수들을 규명하는데 초점을 맞추었다. 연구대상은 중국 상하이 지역에서 외국계 화장품 공급업체와 거래하고 있는 현지의 뷰티숍으로 선정하였고 설문조사를 수행하여 실증분석을 하였다. 표본은 상하이의 전체 뷰티숍 리스트를 바탕으로 중ㆍ대형 뷰티숍을 단순 무작위 표본추출법에 의해 선발하였고, 그 수는 72개였다. 회귀 분석을 통해 가설을 검증한 결과, 중국 현지 소매업체의 신뢰를 증가시키는 외국계 공급업체의 능력, 문화적 민감성, 그리고 현지 소매업체와의 관시의 영향력과 현지 소매업체의 결속을 증가시키는 외국계 공급업체의 업무 공식화와 문화적 민감성의 영향력 모두가 존재하는 것으로 나타났다. 또한, 공급업체에 대한 소매업체의 결속을 증가시키는 소매업체의 신뢰의 영향력이 존재하는 것으로 나타났다. 그러나 신뢰를 증가시키는 업무 공식화와 결속을 증가시키는 관시의 직접적인 영향력은 나타나지 않았다. 끝으로, 이 연구의 이론적 의의와 관리적 시사점들이 논의되었고, 연구의 한계점들과 향후의 연구방향들이 제시되었다. This study focuses on finding out the determinants of relational quality between the supplier and the retailer in the Chinese cosmetics market. A total of 72 questionnaires were collected by surveying beauty shops which mainly do business with the foreign cosmetics suppliers in Shanghai area. The findings support the premise that a retailer’s trust in a supplier is positively related to the retailer’s commitment. Supplier’s ability, guanxi and cultural sensitivity have positive impacts on trust. Formalization and cultural sensitivity affect commitment positively. But the formalization is not significantly related to the retailer’s trust. The guanxi is not found to be significantly related to the retailer’s commitment yet. Finally, the authors discuss some theoretical contributions, managerial implications. And then, they present limitations of this study and the future research directions.

The Antioxidant Property of Chitosan Green Tea Polyphenols Complex Induces Transglutaminase Activation in Wound Healing

Yao Qin,Xing Wei Guo,Lei Li,Hong Wei Wang,김욱 한국식품영양과학회 2013 Journal of medicinal food Vol.16 No.6

The present study examined, for the first time, the in vitro wound healing potential of chitosan green tea polyphenols (CGP) complex based on the activation of transglutaminase (TGM) genes in epidermal morphogenesis. Response surface methodology was applied to determine the optimal processing condition that gave maximum extraction of green tea polyphenols. The antioxidant activity, scavenging ability, and chelating ability were studied and expressed as average EC50 values of CGP and other treatments. In silico analysis and gene coexpression network was subjected to the TGM sequences analysis. The temporal expressions of TGMs were profiled by semi-quantitative reverse transcription (RT)-PCR technology within 10 days after wounding and 2 days postwounding. CGP showed the effectiveness of antioxidant properties, and the observations of histopathological photography showed advanced tissue granulation and epithelialization formation by CGP treatment. In silico and coexpression analysis confirmed the regulation via TGM gene family in dermatological tissues. RTPCR demonstrated increased levels of TGM1–3 expression induced by CGP treatment. The efficacy of CGP in wound healing based on these results may be ascribed to its antioxidant properties and activation of the expression of TGMs, and is, thus, essential for the facilitated repair of skin injury.

Evidence for relaxed selection of mitogenome in rapid‑flow cyprinids

Yao Lu,Hu Xing,Dongsheng Zhang 한국유전학회 2019 Genes & Genomics Vol.41 No.7

Background Hypoxia adaptation is developed in many fish species, which helped them to habitat most of water bodies. However, fishes living under high oxygen concentration may lose this feature. Rapid flows provide high level and stable dissolved oxygen, which facilitate organism’s oxygen supply and energy production. Previous studies showed that fish species from rapid-flow habitats exhibited lower hypoxia tolerance compared with fish from intermediate- and slow-flow habitats. Mitochondrial genomes code 13 key components in oxidative phosphorylation pathway; these genes may be under relaxed selection in rapid-flow species. Objectives The primary objectives of this study is to investigate the evolutionary patterns of the 13 mitochondrial OXPHOS genes among nine cyprinids from different water bodies and to test the hypotheses that mitochondrial OXPHOS genes may experience relaxed selection in rapid-flow habitats. Methods We classified nine cyprinid fish species into three groups based on their habitats: rapid-flow, intermediate-flow and slow-flow. To detect relaxed selections, we investigated the 13 protein-coding genes with codon evolution programs RELAX; to estimate evolutionary rates among the cyprinids, free-ratio model in Codeml program was applied; Branch-site models were applied to detect positive selection sites. The polymorphisms of homologous sites were evaluated with PROVEAN program and projected to 3D structure prediction of the proteins using SWISS-MODEL. Results We found that nine out of the 13 genes are under relaxed selection in rapid-flow species. Furthermore, dN, dS and dN/dS are relatively increased when compared with those of intermediate-flow species. More amino acid polymorphic sites are presented in rapid-flow species than in intermediate- and slow-flow species. Furthermore, rapid-flow species had more deleterious substitutions than other groups. 3D structure prediction of these proteins and projection of the polymorphic sites indicated that these sites were randomly distributed, suggesting relaxed functional constraints of these proteins in rapid-flow species. Conclusion Our results suggest that mitochondrial genes are under relaxed selection in rapid-flow cyprinids.

Fast Algorithm for Intra Prediction of HEVC Using Adaptive Decision Trees

( Xing Zheng ),( Yao Zhao ),( Huihui Bai ),( Chunyu Lin ) 한국인터넷정보학회 2016 KSII Transactions on Internet and Information Syst Vol.10 No.7

High Efficiency Video Coding (HEVC) Standard, as the latest coding standard, introduces satisfying compression structures with respect to its predecessor Advanced Video Coding (H.264/AVC). The new coding standard can offer improved encoding performance compared with H.264/AVC. However, it also leads to enormous computational complexity that makes it considerably difficult to be implemented in real time application. In this paper, based on machine learning, a fast partitioning method is proposed, which can search for the best splitting structures for Intra-Prediction. In view of the video texture characteristics, we choose the entropy of Gray-Scale Difference Statistics (GDS) and the minimum of Sum of Absolute Transformed Difference (SATD) as two important features, which can make a balance between the computation complexity and classification performance. According to the selected features, adaptive decision trees can be built for the Coding Units (CU) with different size by offline training. Furthermore, by this way, the partition of CUs can be resolved as a binary classification problem. Experimental results have shown that the proposed algorithm can save over 34% encoding time on average, with a negligible Bjontegaard Delta (BD)-rate increase.

Yao-Dong Wu,Qi-Qi Wang,Meng Wang,Hany M. Elsheikha,Xin Yang,Min Hu,Xing-Quan Zhu,Min-Jun Xu 대한기생충학열대의학회 2021 The Korean Journal of Parasitology Vol.59 No.2

Haemonchosis remains a significant problem in small ruminants. In this study, the assay of recombinase polymerase amplification (RPA) combined with the lateral flow strip (LFS-RPA) was established for the rapid detection of Haemonchus contortus in goat feces. The assay used primers and a probe targeting a specific sequence in the ITS-2 gene. We compared the performance of the LFS-RPA assay to a PCR assay. The LFS-RPA had a detection limit of 10 fg DNA, which was 10 times less compared to the lowest detection limit obtained by PCR. Out of 24 goat fecal samples, LFS-RPA assay detected H. contortus DNA with 95.8% sensitivity, compared to PCR, 79.1% sensitivity. LFS-RPA assay did not detect DNA from other related helminth species and demonstrated an adequate tolerance to inhibitors present in the goat feces. Taken together, our results suggest that LFS-RPA assay had a high diagnostic accuracy for the rapid detection of H. contortus and merits further evaluation.

We have investigated the probing beam transmitance due to the photon-induced anisotropy effect in the bacteriorhodopsin/polymer composite film(bR/PC film) by using the probing-pumping beam method under different laser wavelengths. By using a theoretical simulation, we give the characteristics of the birefringence Δn and the dichroism ΔD for various wavelengths of the probing and the pumping beams.
