| 1 | 方解石原位U-Pb测年结合磷灰石裂变径迹方法约束鄂尔多斯盆地西南部构造演化显示文摘鄂尔多斯盆地下古生界油气资源丰富,盆地西南部下古生界海相碳酸盐岩地层沉积厚度大、有机质丰度较高,烃源岩热演化达到过成熟生干气阶段,但是构造演化缺乏深入研究,早期构造事件具体时限是一个亟待解决的关键科学问题。在详细的野外调查、显微结构特征、原位微量元素分析和区域沉积-埋藏演化历史的约束下,结合下古生界碳酸盐岩地层及其断裂破碎带内次生方解石原位U-Pb测年与磷灰石裂变径迹时间-温度曲线模拟结果,揭示了鄂尔多斯盆地西南部晚奥陶世、晚三叠世、晚侏罗世和早白垩世末期—新生代以来的4期构造事件。结果表明研究区晚奥陶世(452±13)Ma存在一期热液改造事件,可能与加里东期原特提斯洋俯冲闭合密切相关;印支期(214±22)Ma的断裂活动是引起区域构造-热事件的重要原因,印支期构造事件规模有限;燕山期和喜马拉雅期构造活动强烈,造成鄂尔多斯盆地西南部大幅度隆升和强烈剥蚀。盆地西南部多阶段复杂的构造演化历史导致油气保存条件破坏严重,对寻找古生界天然气藏不利,应重视盆地天然气保存条件的研究。研究结果对鄂尔多斯盆地古生界油气勘探工作有重要指导意义。将低温热年代学与断裂带方解石原位U-Pb定年相结合分析构造演化的新思路,为解析复杂叠合盆地盆缘带构造演化及其后期改造过程的研究提供了新途径。 | 杨鹏 任战利 Jianxin Zhao Ai Duc Nguyen Yuexing Feng 祁凯 王琨 | 2021 | 石油与天然气地质2021，42，5： | 7 |
| 2 | Stem cell-based therapy for human diseases显示文摘Recent advancements in stem cell technology open a new door for patients suffering from diseases and disorders that have yet to be treated.Stem cell-based therapy,including human pluripotent stem cells(hPsCs)and multipotent mesenchymal stem cells(MSCs),has recently emerged as a key player in regenerative medicine.hPSCs are defined as self-renewable cell types conferring the ability to differentiate into various cellular phenotypes of the human body,including three germ layers.MsCs are multipotent progenitor cells possessing self-renewal ability(limited in vitro)and differentiation potential into mesenchymal lineages,according to the International Society for Cell and Gene Therapy(ISCT).This review provides an update on recent clinical applications using either hPSCs or MSCs derived from bone marrow(BM),adipose tissue(AT),or the umbilical cord(UC)for the treatment of human diseases,including neurological disorders,pulmonary dysfunctions,metabolic/endocrine-related diseases,reproductive disorders,skin burns,and cardiovascular conditions.Moreover,we discuss our own clinical trial experiences on targeted therapies using MsCs in a clinical setting,and we propose and discuss the MSC tissue origin concept and how MSC origin may contribute to the role of MSCs in downstream applications,with the ultimate objective of facilitating translational research in regenerative medicine into clinical applications.The mechanisms discussed here support the proposed hypothesis that BM-MSCs are potentially good candidates for brain and spinal cord injury treatment,AT-MSCs are potentially good candidates for reproductive disorder treatment and skin regeneration,and UC-MsCs are potentially good candidates for pulmonary disease and acute respiratory distress svndrometreatment. | Duc M.Hoang Phuong T.Pham Trung Q.Bach Anh T.L.Ngo Quyen T.Nguyen Trang T.K.Phan Giang H.Nguyen Phuong T.T.Le Van T.Hoang Nicholas R.Forsyth Michael Heke Liem Thanh Nguyen | 2022 | Signal Transduction and Targeted Therapy2022，7，9： | 7 |
| 3 | 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 |

| 5 | Double-loop Control Structure Using Proportional Resonant and Sequence-decoupled Resonant Controllers in Static Coordinates for Dynamic Voltage Restorer显示文摘Among incidents on grids,the sag/swell voltage is considered as the most frequent incident.To solve this problem,custom power devices are used.In particular,the dynamic voltage restorer(DVR)is a modern and efficient customer device.DVRs are used to mitigate voltage sag/swells and harmonics on the load bus,thus protecting the sensitive loads.The DVR is a serial compensator that applies a voltage to the point of common coupling to maintain the voltage of sensitive load at the nominal value.To improve the performance of DVRs,in this study,the control strategy of the two-stage loop circuit is implemented.The external voltage control loop uses a sequence-decoupled resonant(SDR)controller,and the inner current-control loop uses the proportional resonant(PR)controller implemented in the stationary frameαβ. | Vu Thai Hung Hongchun Shu Le Ngoc Giang Nguyen Duc The | 2019 | Chinese Journal of Electrical Engineering2019，5，3： | 4 |
| 6 | Genetic diversity in two threatened species in Vietnam:Taxus chinensis and Taxus wallichiana显示文摘Taxus chinensis and T. wallichiana in have been threatened in their distribution areas in recent decades because of their over-exploitation and reduction and destruction of native habitats. Determining the genetic diversity in populations of the two species will provide guidelines for their protection and preservation. Two hundred and fifteen trees from six populations of T. chinensis and150 sampled trees of T. wallichiana were sampled. Six microsatellite primer pairs selected from 16 primer pairs were used to investigate genetic variation at the population and species levels. Five yielded polymorphic alleles, and among the 13 putative alleles amplified, 11 were polymorphic(accounting for 76.33 %).Shannon's information index(I) and percentage of polymorphic bands(PPB)(I = 0.202 and PPB = 67.22 % for T. chinensis; I = 0.217 and PPB = 65.03 % for T. wallichiana). Both species had low levels of genetic diversity(mean H_o= 0.107, H_e= 0.121 for T. chinensis; H_o= 0.095, H_e= 0.109 for T. wallichiana). Genetic differentiation among populations was higher(FST= 0.189) for T. chinensis and lower(0.156) for T.wallichiana, indicating limited gene flow(Nm) among populations for T. chinensis(0.68) and T. wallichiana(0.65).Variation among individuals of T. chinensis was 63.59 and73.12 % for T. wallichiana. Thus, the threatened status of the two conifers is related to a lack of genetic diversity. All populations are isolated in small forest remnants. An ex situ conservation site should be established with a new population for these species that comprises all the genetic groups for the best chance to improve their fitness under environmental stresses. | Dinh Duy Vu Thi Tuyet Xuan Bui Minh Tam Nguyen Dinh Giap Vu Minh Duc Nguyen Van Thang Bui Xiaohua Huang Yi Zhang | 2017 | Journal of Forestry Research2017，28，2： | 4 |

| 9 | Ethanol extracts of Scutellaria baicalensis protect against lipopolysaccharide-induced acute liver injury in mice显示文摘Objective: To investigated the protective potential of ethanol extracts of Scutellaria baicalensis(S. baicalensis) against lipopolysaccharide(LPS)-induced liver injury. Methods: Dried roots of S. baicalensis were extracted with ethanol and concentrated to yield a dry residue. Mice were administered 200 mg/kg of the ethanol extracts orally once daily for one week. Animals were subsequently administered a single dose of LPS(5 mg/kg of body weight, intraperitoneal injection). Both protein and m RNA levels of cytokines, such as tumor necrosis factor alpha, interleukin-1β, and interleukin-6 in liver tissues were evaluated by ELISA assay and quantitative PCR. C yclooxygenase-2, inducible nitric oxide synthase, and nuclear factor-κB protein levels in liver tissues were analyzed by western blotting. Results: Liver injury induced by LPS signifi cantly increased necrosis factor alpha, interleukin-1β, interleukin-6, cyclooxygenase-2, inducible nitric oxide synthase, and nuclear factor-κB in liver tissues. Treatment with ethanol extracts of S. baicalensis prevented all of these observed changes associated with LPS-induced injury in liver mice.Conclusions: Our study showed that S. baicalensis is potentially protective against LPS-induced liver injury in mice. | Hai Nguyen Thanh Hue Pham Thi Minh Tuan Anh Le Huong Duong Thi Ly Tung Nguyen Huu Loi Vu Duc Thu Dang Kim Tung Bui Thanh | 2015 | Asian Pacific Journal of Tropical Biomedicine2015，5，9： | 3 |
| 10 | Chrysoeriol ameliorates hyperglycemia by regulating the carbohydrate metabolic enzymes in streptozotocin-induced diabetic rats显示文摘The present study aimed to evaluate the effects of chrysoeriol from Cardiospermum halicacabum in streptozotocin induced Wistar rats.Thirty rats were categorized as control,diabetic control supplemented with 0,20 mg/kg chrysoeriol and 600μg/kg BW of glibenclamide for 45-day trial period.Our results indicated that the inclusion of chrysoeriol(20 mg/kg)showed a significant reduction in plasma glucose,hemoglobin and glycosylated hemoglobin level with a rising of plasma insulin sensitivity.Further,downregulated enzymes including glucose 6-phosphatase,fructose 1,6-bisphosphatase,and glycogen phosphorylase as well upregulated enzymes such as hexokinase,glucose-6-phosphate dehydrogenase,pyruvate kinase,and hepatic glycogen content.There was a diminish action found in liver glycogen synthase of tested rat with a rise in gamma-glutamyl transpeptidase,towards normal levels upon treatment with chrysoeriol.The histopathological study confirmed that renewal of the beta cells of pancreatic of chrysoeriol and glibenclamide treated rats.In addition,the molecular docking of chrysoeriol against glycolytic enzymes including hexokinase,glucose-6-phosphate dehydrogenase,pyruvate kinase,using Argus software shows chrysoeriol had greatest ligand binding energy as equivalent to glibenclamide,as a standard drug.Thus,chrysoeriol found to be non-toxic with potential regulation on glycemic control and upregulation of the carbohydrate metabolic enzymes. | Baskaran Krishnan Abirami Ramu Ganesan Ravindran Balasubramani Dinh Duc Nguyen Soon Woong Chang Shaoyun Wang Jianbo Xiao Balamuralikrishnan Balasubramanian | 2020 | Food Science and Human Wellness2020，9，4： | 3 |
| 11 | Protective effect of Tetracera scandens L.leaf extract against CCl_4-induced acute liver injury in rats显示文摘Objective:To investigate the protective potential of ethanolic extracts of Tetracera scandens L.(T.scandens) against CCl_4 induced oxidative stress in liver tissues.Methods:Dried leaf powder of T.scandens was extracted with ethanol and concentrated to yield a dry residue.Rats were administered with 100 mg/kg of ethanolic extracts orally once daily for one week.Animals were subsequently administered with a single dose of CCl_4(I mL/kg body weight,intraperitoneal injection).Various assays,such as serum levels of alanine aminotransferase,aspartate aminotransferase,lipid peroxidation,protein oxidation(carbonyl protein group),tumor necrosis factor alpha,catalase,superoxide dismutase,and glutathione peroxidase,were used to assess damage caused by CCl_4 and the protective effects of the ethanol extract on liver tissues.Results:Hepatotoxicity induced by CCl_4 was evidenced by a significant increase in serum aspartate aminotransferase and alanine aminotransferase level,lipid peroxidation,protein carbonyl group,and tumor necrosis factor alpha,as well as decreased activity of the hepatic antioxidant enzymes(catalase.superoxide dismutase.and glutathione peroxidase).Treatment with ethanolic T.scandens extracts prevented all of these typically observed changes in CCl_4-treated rats.Conclusions:Our findings indicate that T.scandens has a significant protective effect against CCl_4 induced hepatotoxicity in rat.which may be due to its antioxidant properties. | Tung Bui Thanh Hai Nguyen Thanh Hue Pham Thi Minh Huong Le-Thi-Thu Huong Duong Thi Ly Loi Vu Duc | 2015 | Asian Pacific Journal of Tropical Biomedicine2015，5，3： | 3 |
