RFG phosphorylated AMP-activated protein kinase (AMPK) in a liver kinase B (LKB) 1-independent manner. Moreover, the anti-adipogenic effect of RFG was blocked by AMPK inhibitor. These results suggest that RFG inhibits lipid accumulation via AMPK signaling. Furthermore, RFG reduced the body weight, size of epididymal white adipose tissue (eWAT), and fatty liver in the mice.

Han-Qin Shen,Xiangcong Liu,Pengfei Zhang,Lei Wang,Yan-ling Liu,Le-yi Zhang,Peng-shuai Liang,Chang-xu Song 대한수의학회 2018 Journal of Veterinary Science Vol.19 No.3

Recently, a novel atypical porcine pestivirus (APPV) in pig was reported. In this study, two APPV strains, APPV-China/GZ01/2016 (GZ01) and APPV-China/GD-SD/2016 (GD-SD), were identified in two newborn piglet herds with congenital tremor from China. The open reading frame of the two strains shared an 83.5% nucleotide identity. Phylogenetically, the APPV strains were placed into two groups: GZ01 belonged to group I and GD-SD belonged to group II. A high viral load was detected in the cerebellum (quantification cycles < 26). Further studies should be carried out to thoroughly elucidate the development of congenital tremors caused by APPV.

본 논문은 중국 상해를 중심으로 로지스틱 서비스를 이용하는 기업들의 로지스틱 아웃소싱 실태에 대한 설문조사를 통하여 중국의 물류아웃소싱 관행에 대한 조사연구이다. 중국 상해에 소재하는 158개 제조기업을 대상으로 설문조사를 했다. 연구 결과는 첫째, 전형적 물류를 아웃소싱 하는 제조기업들은 서비스 제공업자들과 장기적 관계를 유지하고 또한 다수의 물류서비스업자들로부터의 물류서비스 구매를 선호했다. 둘째, 대부분의 서비스 이용기업들은 물류서비스 제공기업들에 대하여 만족했고, 물류기업들에게 자사의 물류를 아웃소싱 할 때, 자사의 고객만족도, 물류 수준과 수익개선에 긍정적 영향을 미치는 것으로 나타났다. 셋째, 물류서비스를 이용하는 제조기업들은 물류기업을 선택할 때 가격수준, 핵심적 경쟁력과 평판을 가장 중요한 요인으로 하는 것으로 나타났다. 넷째, 중국에서 3PL 등의 물류전문서비스 사업이 초기단계이지만, 앞으로 발전 잠재력이 매우 큰 것으로 조사되었다. 따라서 본 논문은 상해를 중심으로 중국에서 영업을 하고 중국 국내물류기업 또는 우리나라 투자기업을 포함한 외자물류기업들에게 물류서비스 이용기업들의 물류 아웃소싱 실태와 관행에 대한 정보를 제공함으로 물류서비스산업의 발전에 도움이 될 것으로 사료된다. This paper analyses the results of the survey questionnaires which are made for logistics services users in Shanghai, China. Based on 158 valid users' responses, the study results show that the typical outsourcing logistics users prefer to set up long term relationship with providers and buy services from multiple providers. Most users are satisfied with their providers and believe that outsourcing logistics services has led to positive impact on their customer satisfaction, logistics service levels and revenue improvement. Price levers, core competences, reputation are critical in the selection of an outsourcing logistics provider for users in this study. This study indicates that the market for 3PL services in China has a reasonable potential for further development, though 3PL practices are still at a nascent stage in China. This paper presents full details and implications of the results of the survey and then provides some helpful suggestion for the development of Chinese logistics industry and Chinese logistics companies.

As part of our ongoing influenza surveillance program in South China, 19 field strains of H9N2 subtype avian influenza viruses (AIVs) wereisolated from dead or diseased chicken flocks in Guangdong province, South China, between 2012 and 2013. Hemagglutinin (HA) genes ofthese strains were sequenced and analyzed and phylogenic analysis showed that 12 of the 19 isolates belonged to the lineage h9.4.2.5, whilethe other seven belonged to h9.4.2.6. Specifically, we found that all of the viruses isolated in 2013 belonged to lineage h9.4.2.5. The lineageh9.4.2.5 viruses contained a PSRSSR↓GLF motif at HA cleavage site, while the lineage h9.4.2.6 viruses contained a PARSSR↓GLF at thesame position. Most of the isolates in lineage h9.4.2.5 lost one potential glycosylation site at residues 200–202, and had an additional oneat residues 295–297 in HA1. Notably, 19 isolates had an amino acid exchange (Q226L) in the receptor binding site, which indicated that theviruses had potential affinity of binding to human like receptor. The present study shows the importance of continuing surveillance of newH9N2 strains to better prepare for the next epidemic or pandemic outbreak of H9N2 AIV infections in chicken flocks.

Y-Single Nucleotide Polymorphisms Diversity in Chinese Indigenous Horse

Han, Haoyuan,Zhang, Qin,Gao, Kexin,Yue, Xiangpeng,Zhang, Tao,Dang, Ruihua,Lan, Xianyong,Chen, Hong,Lei, Chuzhao Asian Australasian Association of Animal Productio 2015 Animal Bioscience Vol.28 No.8

In contrast to high genetic diversity of mitochondrial DNA (mtDNA), equine Y chromosome shows extremely low variability, implying limited patrilines in the domesticated horse. In this study, we applied direct sequencing and restriction fragment length polymorphism (RFLP) methods to investigate the polymorphisms of 33 Y chromosome specific loci in 304 Chinese indigenous horses from 13 breeds. Consequently, two Y-single nucleotide polymorphisms (SNPs) (Y-45701/997 and Y-50869) and one Y-indel (Y-45288) were identified. Of those, the Y-50869 (T>A) revealed the highest variation frequency (24.67%), whereas it was only 3.29% and 1.97% in Y-45288 (T/-) and Y-45701/997 (G>T) locus, respectively. These three mutations accounted for 27.96% of the total samples and identified five Y-SNP haplotypes, demonstrating genetic diversity of Y chromosome in Chinese horses. In addition, all the five YSNP haplotypes were shared by different breeds. Among 13 horse breeds analyzed, Balikun horse displayed the highest nucleotide diversity (${\pi}=5.6{\times}10^{-4}$) and haplotype diversity (h = 0.527), while Ningqiang horse showed the lowest nucleotide diversity (${\pi}=0.00000$) and haplotype diversity (h = 0.000). The results also revealed that Chinese horses had a different polymorphic pattern of Y chromosome from European and American horses. In conclusion, Chinese horses revealed genetic diversity of Y chromosome, however more efforts should be made to better understand the domestication and paternal origin of Chinese indigenous horses.

Polysaccharide from Polygonatum Inhibits the Proliferation of Prostate Cancer-Associated Fibroblasts Cells

Han, Shu-Yu,Hu, Ming-Hua,Qi, Guan-Yun,Ma, Chao-Xiong,Wang, Yuan-Yuan,Ma, Fang-Li,Tao, Ning,Qin, Zhi-Hai Asian Pacific Journal of Cancer Prevention 2016 Asian Pacific journal of cancer prevention Vol.17 No.8

Inhibition of cancer-associated fibroblasts (CAFs) may improve the efficacy of cancer therapy. Polysaccharide extracted from polygonatum can selectively inhibit the growth of prostate-CAFs (p<0.001) without inhibiting the growth of normal fibroblasts (NAFs). Polysaccharides from polygonatum stimulate autophagy of prostate-CAFs. 3-methyl-adenine(3-MA) is an autophagy inhibitor. 3-MA was added to prostate-CAFs with polysaccharide from polygonatum to determine whether autophagy plays an important role in the restrained effect. Finally, polysaccharide from polygonatum treatment significantly increased the activation of Beclin-1 and LC3, key autophagy proteins. Polysaccharide from polygonatum stimulates autophagy of prostate-CAFs and inhibits prostate-CAF growth, indicating that a novel anti-cancer strategy involves inhibiting the growth of prostate-CAFs.

Map-Based Control for Autonomous Tractors

Han, Shufeng,Shin, Beom Soo,Zhang, Qin 한국농업기계학회 2003 Agricultural and Biosystems Engineering Vol.4 No.1

An autonomous tractor requires not only automatic steering(automatic guidance) but also automated control of tractor functions and implement operations. Examples of tractor functions include engine throttle, transmission speed, and 3-point hitch position. Implement operations include tillage, planting, and cultivating. This article provides an overview of a map-based methodology used for the implementation of autonomous field operations of agricultural tractors. The procedure for developing autonomous field operation maps were presented, and several important issues in the implementation of map-based autonomous operations were discussed. These issues included combining field operation maps, position offset, and real-time sensing and update of field operation maps.

Diffusion-Weighted Imaging for the Left Hepatic Lobe has Higher Diagnostic Accuracy for Malignant Focal Liver Lesions

Han, Xue,Dong, Yin,Xiu, Jian-Jun,Zhang, Jie,Huang, Zhao-Qin,Cai, Shi-Feng,Yuan, Xian-Shun,Liu, Qing-Wei Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.15

Background: This study was conducted to investigate whether apparent diffusion coefficient (ADC) measurements by dividing the liver into left and right hepatic lobes may be utilized to improve the accuracy of differential diagnosis of benign and malignant focal liver lesions. Materials and Methods: A total of 269 consecutive patients with 429 focal liver lesions were examined by 3-T magnetic resonance imaging that included diffusion-weighted imaging. For 58 patients with focal liver lesions of the same etiology in left and right hepatic lobes, ADCs of normal liver parenchyma and focal liver lesions were calculated and compared using the paired t-test. For all 269 patients, ADC cutoffs for focal liver lesions and diagnostic accuracy in the left hepatic lobe, right hepatic lobe and whole liver were evaluated by receiver operating characteristic curve analysis. Results: For the group of 58 patients, mean ADCs of normal liver parenchyma and focal liver lesions in the left hepatic lobe were significantly higher than those in the right hepatic lobe. For differentiating malignant lesions from benign lesions in all patients, the sensitivity and specificity were 92.6% and 92.0% in the left hepatic lobe, 94.4% and 94.4% in the right hepatic lobe, and 90.4% and 94.7% in the whole liver, respectively. The area under the curve of the right hepatic lobe, but not the left hepatic lobe, was higher than that of the whole liver. Conclusions: ADCs of normal liver parenchyma and focal liver lesions in the left hepatic lobe were significantly higher than those in the right hepatic lobe. Optimal ADC cutoff for focal liver lesions in the right hepatic lobe, but not in the left hepatic lobe, had higher diagnostic accuracy compared with that in the whole liver.
