| 2 | Treatment responses in Asians and Caucasians with chronic hepatitis C infection显示文摘AIM:To conduct a multicentre retrospective review of virological response rates in Asians infected with genotype 1 chronic hepatitis C(CHC) treated with combination interferon and ribavirin and then to compare their responses to that among Caucasians.METHODS:Asian patients infected with genotype 1 CHC treated at 4 Australian centres between 2001 to 2005 were identified through hospital databases.Baseline demographic characteristics,biochemical,virological and histological data and details of treatment were collected.Sustained virological responses(SVR) in this cohort were then compared to that in Caucasian subjects,matched by genotype,age,gender and the stage of hepatic fibrosis.RESULTS:A total of 108 Asians with genotype 1 CHC were identified.The end of treatment response(ETR) for the cohort was 79% while the SVR was 67%.Due to the relatively advanced age of the Asian cohort,only sixty-four subjects could be matched with Caucasians.The ETR among matched Asians and Caucasians was 81% and 56% respectively(P=0.003),while the SVR rates were 73% and 36%(P <0.001) respectively.This difference remained significant after adjusting for other predictive variables. | Kenneth K Yan Marianne Guirgis Amany Zekry Thuy Dinh Anouk Dev Jacob George Alice Lee | 2008 | World Journal of Gastroenterology2008,14,21: | 12 |
| 3 | 基于ENVISAT ASAR数据的水稻估产方案显示文摘水稻多生长在温暖潮湿的多云多雨地区,使雷达遥感成为水稻遥感监测的重要手段之一.因此,提出应用多时相、多极化ENVISAT ASAR数据进行区域水稻估产的方案.首先利用ASAR数据进行水稻制图,提取水稻种植分布图和多时相水稻后向散射系数.随后,基于像元尺度,采用同化估产方法,以LAI为结合点,将水稻作物模型ORYZA2000与半经验水稻后向散射模型结合,建立嵌套模型模拟多时相水稻后向散射系数.对ORYZA2000模型进行参数敏感性分析,选择水稻出苗期和播种密度为参数优化对象.利用全局优化算法SCE-UA对优化参数进行重新初始化,以使模拟的水稻后向散射系数与实测值误差最小,并利用优化后的ORYZA2000模型计算每个像元的水稻产量,生成区域的水稻产量分布图.最后,使用2006年在中国兴化地区进行的水稻同步试验数据对该方案进行了验证.结果表明,由于采用潜在生长条件模拟,模拟的水稻产量明显高于实测产量,其平均值比实际情形高约13,根均方误差达到1133kg/hm2,但获取的水稻产量分布图能够描绘研究区水稻实际产量的分布趋势.由此可见,该方案为多云多雨地区的水稻遥感监测提供了重要参考. | 申双和 杨沈斌 李秉柏 谭炳香 李增元 Le Toan Thuy | 2009 | 中国科学(D辑)2009,,6: | 11 |
| 4 | The first dinosaur tracksite from Xinjiang, NW China (Middle Jurassic Sanjianfang Formation, Turpan Basin)──a preliminary report显示文摘A new dinosaur tracksite was discovered in a steeply inclined sandstone layer of the Middle Jurassic Sanjianfang Formation in the Shanshan area of the Turpan Basin. The site is the first record of dinosaur footprints from Xinjiang Province in northwestern China. More than 150 tridactyl theropod dinosaur footprints are preserved as positive hyporeliefs on the lower bedding plane of a fine-grained sandstone body. Most of the footprints are isolated and appear to be randomly distributed. Some show well defined phalangeal pads, heels and rarely indistinct impressions of the distal part of the metatarsus. Two distinct morphotypes are present: a larger type with relatively broad pads shows similarities to Changpeipus and Megalosauripus, and a slightly smaller, slender and gracile type which is similar to Grallator, Eubrontes and Anchisauripus. In both morphotypes, digit III is the longest with a length between 11.4 and 33.6 cm. A single imprint shows prominent scratches, probably formed during slipping of the track maker. | Oliver WINCS Rico SCHELLHORN Heinrich MALLISON Ben THUY Wenhao WU Ge SUN | 2007 | Global Geology2007,10,2: | 8 |

| 6 | A scheme for regional rice yield estimation using ENVISAT ASAR data显示文摘Information on rice growing areas and rice production is critical for most rice growing countries to make state and economic policies. However, the areas where rice crop is cultivated are often cloudy and rainy, which entails the use of radar remote sensing data for rice monitoring. In this paper, a practical scheme to integrate multi-temporal and multi-polarization ENVISAT ASAR data into rice crop model for regional rice yield estimation has been presented. To achieve this, rice distribution information should be obtained first by rice mapping method to retrieve rice fields from ASAR images, and then an assimilation method is applied to use the observed multi-temporal rice backscattering coefficients which are grouped for each rice pixel to re-initialize ORYZA2000 to predict rice yield. The assimilation method re-initializes the model with optimal input parameters, allowing a better temporal agreement between the rice backscattering coefficients retrieved from ASAR data and the rice backscattering coefficients simulated by a coupled model, i.e., the combination of ORYZA2000 and a semi-empirical rice backscatter model through LAI. The SCE-UA optimization algorithm is employed to determine the optimal set of input parameters. After the re-initialization, rice yield for each rice pixel is calculated, and the yield map over the area of interest is produced. The scheme was validated over Xinghua study area located in the middle of Jiangsu Province of China by using the data set of an experimental campaign carried out during the 2006 rice season. The result shows that the obtained rice yield map generally overestimates the actual rice production by 13% on average and with a root mean square error of approximately 1133 kg/ha on validation sites, but the tendency of rice growth status and spatial variation of the rice yield are well predicted and highly consistent with the actual production variation. | LE TOAN Thuy | 2009 | Science China Earth Sciences2009,52,8: | 7 |

| 13 | Xanthine oxidase inhibitors from Archidendron clypearia(Jack.) I.C. Nielsen: Results from systematic screening of Vietnamese medicinal plants显示文摘Objective: To screen Vietnamese medicinal plants for xanthine oxidase(XO) inhibitory activity and to isolate XO inhibitor(s) from the most active plant. Methods: The plants materials were extracted by methanol. The active plant materials were fractionated using different organic solvents, including n-hexane, ethyl acetate, and n-butanol. Bioassay-guided fractionation and column chromatography were used to isolate compounds. The compounds structures were elucidated by analysis of spectroscopic data, including IR, MS, and NMR. Results: Three hundreds and eleven methanol extracts(CME) belonging to 301 Vietnamese herbs were screened for XO inhibitory activity. Among these plants, 57 extracts displayed XO inhibitory activity at 100 μg/m L with inhibition rates of over 50%. The extracts of Archidendron clypearia, Smilax poilanei, Linociera ramiflora and Passiflora foetida exhibited the greatest potency with IC_(50) values below 30 μg/m L. Chemical study performed on the extract of Archidendron clypearia resulted in the isolation of six compounds, including 1-octacosanol, docosenoic acid, daucosterol, methyl gallate, quercitrin and(-)-7-O-galloyltricetiflavan. The compound(-)-7-O-galloyltricetiflavan showed the most potent XO inhibitory activity with an IC_(50) value of 25.5 μmol/L. Conclusions: From this investigation, four Vietnamese medicinal plants were identified to have XO inhibitory effects with IC_(50) values of the methanol extracts below 30 μg/m L. Compound(-)-7-O-galloyltricetiflavan was identified as an XO inhibitor from Archidendron clypearia with IC_(50) value of 25.5 μmol/L. | Nguyen Thuy Duong Pham Duc Vinh Phuong Thien Thuong Nguyen Thi Hoai Le Nguyen Thanh Tran The Bach Nguyen Hai Nam Nguyen Hoang Anh | 2017 | Asian Pacific Journal of Tropical Medicine2017,10,6: | 5 |
| 14 | RECENT PROGRESS IN STORM SURGE FORECASTING显示文摘This report briefly summarizes recent progress in storm surge forecasts, one of topics discussed during the fourth International Workshop on Tropical Cyclone Landfall Process(IWTCLP 4) held during 5-8 December, 2017. In the workshop, improvement of storm surge forecasting system was mainly discussed with relevance to the problem of estimating the impacts of tropical cyclone landfall.To deal with storm surges, accurate TC condition(predictions and forecasts) as input, reasonable storm surge predictions(with forecasting systems), and effective advisories/warnings(i.e. useful information products) are necessary. Therefore, we need to improve storm surge related matters systematically: input, prediction system, and ef fective information.This report tries to highlight recent progress in the field of storm surges in relation to three key points: improvement in storm surge forecasting models/system, TC conditions as input for storm surge predictions, and informative products for end users. | NADAO KOHNO SHISHIR K.DUBE MIKHAIL ENTEL S.H.M.FAKHRUDDIN DIANA GREENSLADE MARIE-DOMINIQUE LEROUX JAMIE RHOME NGUYEN BA THUY | 2018 | Tropical Cyclone Research and Review2018,7,2: | 4 |
| 15 | 全身麻醉剂激活杏仁核内一个强效的中枢镇痛环路显示文摘全身麻醉产生的镇痛作用独立于其引起意识消失的作用,但背后机制却不清楚。本研究假设全身麻醉药通过激活高级中枢产生镇痛。研究者发现小鼠中央杏仁核(CeA)存在一类特殊的由全身麻醉药激活的GABA能神经元集群(称作CeAGA神经元)。在体钙成像实验显示不同的全身麻醉药可激活共同的CeAGA神经元集群。CeAGA神经元有本底放电活动,但主要是反应小鼠身体的内部状态。光遗传兴奋CeAGA神经元显著减少疼痛引发的反射性行为和自愈性(如舔舐、擦拭)行为以及抑制慢性神经病理性疼痛引发的机械痛敏。相反,抑制CeAGA神经元活动会加剧疼痛,带来强烈的厌恶感并抑制低剂量氯胺酮的镇痛效应。此外,CeAGA神经元广泛投射到痛觉相关脑区。本研究表明CeAGA是缓解慢性疼痛的潜在的强效治疗靶标。 | Thuy Hua Bin Chen Dongye Lu 李紫阳(译) 张玲(校) | 2020 | 中国疼痛医学杂志2020,26,11: | 4 |

| 17 | Genome-wide association study identifies QTL for eight fruit traits in cultivated tomato (Solanum lycopersicum L.)显示文摘Genome-wide association study(GWAS)is effective in identifying favorable alleles for traits of interest with high mapping resolution in crop species.In this study,we conducted GWAS to explore quantitative trait loci(QTL)for eight fruit traits using 162 tomato accessions with diverse genetic backgrounds.The eight traits included fruit weight,fruit width,fruit height,fruit shape index,pericarp thickness,locule number,fruit firmness,and brix.Phenotypic variations of these traits in the tomato collection were evaluated with three replicates in field trials over three years.We filtered 34,550 confident SNPs from the 51K Axiom®tomato array based on<10%of missing data and>5%of minor allele frequency for association analysis.The 162 tomato accessions were divided into seven clusters and their membership coefficients were used to account for population structure along with a kinship matrix.To identify marker-trait associations(MTAs),four phenotypic data sets representing each of three years and combined were independently analyzed in the multilocus mixed model(MLMM).A total of 30 significant MTAs was detected over data sets for eight fruit traits at P<0.0005.The number of MTA per trait ranged from one(brix)to seven(fruit weight and fruit width).Two SNP markers on chromosomes 1 and 2 were significantly associated with multiple traits,suggesting pleiotropic effects of QTL.Furthermore,16 of 30 MTAs suggest potential novel QTL for eight fruit traits.These results facilitate genetic dissection of tomato fruit traits and provide a useful resource to develop molecular tools for improving fruit traits via marker-assisted selection and genomic selection in tomato breeding programs. | Minkyung Kim Thuy Tien Phan Nguyen Joon-Hyung Ahn Gi-Jun Kim Sung-Chur Sim | 2021 | Horticulture Research2021,8,1: | 3 |

| 19 | GIS-based landslide susceptibility modeling:A comparison between fuzzy multi-criteria and machine learning algorithms显示文摘Hazards and disasters have always negative impacts on the way of life.Landslide is an overwhelming natural as well as man-made disaster that causes loss of natural resources and human properties throughout theworld.The present study aimed to assess and compare the prediction efficiency of different models in landslide susceptibility in the Kysuca river basin,Slovakia.In this regard,the fuzzy decision-making trial and evaluation laboratory combining with the analytic network process(FDEMATEL-ANP),Naïve Bayes(NB)classifier,and random forest(RF)classifier were considered.Initially,a landslide inventory map was produced with 2000 landslide and nonlandslide points by randomly dividedwith a ratio of 70%:30%for training and testing,respectively.The geospatial database for assessing the landslide susceptibility was generated with the help of 16 landslide conditioning factors by allowing for topographical,hydrological,lithological,and land cover factors.The ReliefF methodwas considered for determining the significance of selected conditioning factors and inclusion in the model building.Consequently,the landslide susceptibility maps(LSMs)were generated using the FDEMATEL-ANP,Naïve Bayes(NB)classifier,and random forest(RF)classifier models.Finally,the area under curve(AUC)and different arithmetic evaluation were used for validating and comparing the results and models.The results revealed that random forest(RF)classifier is a promising and optimum model for landslide susceptibility in the study area with a very high value of area under curve(AUC=0.954),lower value of mean absolute error(MAE=0.1238)and root mean square error(RMSE=0.2555),and higher value of Kappa index(K=0.8435)and overall accuracy(OAC=92.2%). | Sk Ajim Ali Farhana Parvin Jana Vojteková Romulus Costache Nguyen Thi Thuy Linh Quoc Bao Pham Matej Vojtek Ljubomir Gigović Ateeque Ahmad Mohammad Ali Ghorbani | 2021 | Geoscience Frontiers2021,12,2: | 3 |
| 20 | Anti-inflammatory effects of fatty acids isolated from Chromolaena odorata显示文摘Objective:To identify inhibitors of nitric oxide production and NF-κB activity from Chromolaena odorata(C.odorata).Methods:The compounds isolated from the aerial parts of C.odorata by bioassay-guided fractionation were investigated for their inhibitory effects on the NO production and NF-κB activity in LPS-stimulated RAW264.7 cells.Results:Six fatty acids (S)-coriolic acid(1),(S)-coriolic acid methyl ester(2),(5)-15,16-didehydrocoriolic acid(3),(S)- 15,16-didehydrocoriolic acid methyl ester(4),linoleamide(5) and linolenamide(6) were isolated. All compounds inhibited the NO production at concentrations consistent with those required for NF-κB inhibition.Compound 2 was the most active with the IC50 values of 5.22 and 5.73μM. The addition of a double bond in the fatty chain decreased the inhibitory effects while the methyl esterification increased the activities.Conclusions:The fatty acid components in C.odorata with NF-κB inhibitory activity could explain the anti-inflammation property of this plant in traditional medicine.This study could also contribute to the better use of C.odorata for human health care. | Tran Thi Hong Hanh Dan Thi Thuy Hang Chau Van Minh Nguyen Tien Dat | 2011 | Asian Pacific Journal of Tropical Medicine2011,4,10: | 3 |
