| 1 | Dynamic membrane bioreactor performance enhancement by powdered activated carbon addition:Evaluation of sludge morphological,aggregative and microbial properties显示文摘The effects of powdered activated carbon(PAC) addition on sludge morphological, aggregative and microbial properties in a dynamic membrane bioreactor(DMBR) were investigated to explore the enhancement mechanism of pollutants removal and filtration performance. Sludge properties were analyzed through various analytical measurements. The results showed that the improved sludge aggregation ability and the evolution of microbial communities affected sludge morphology in PAC-DMBR, as evidenced by the formation of large, regularly shaped and strengthened sludge flocs. The modifications of sludge characteristics promoted the formation process and filtration flux of the dynamic membrane(DM) layer. Additionally, PAC addition did not exert very significant influence on the propagation of eukaryotes(protists and metazoans)and microbial metabolic activity. High-throughput pyrosequencing results indicated that adding PAC improved the bacterial diversity in activated sludge, as PAC addition brought about additional microenvironment in the form of biological PAC(BPAC), which promoted the enrichment of Acinetobacter(13.9%), Comamonas(2.9%), Flavobacterium(0.31%) and Pseudomonas(0.62%), all contributing to sludge flocs formation and several(such as Acinetobacter) capable of biodegrading relatively complex organics. Therefore, PAC addition could favorably modify sludge properties from various aspects and thus enhance the DMBR performance. | Zhenzhen Yu Yisong Hu Mawuli Dzakpasu Xiaochang C.Wang Huu Hao Ngo | 2019 | Journal of Environmental Sciences2019，31，1： | 9 |

| 3 | Vitamin D deficiency and hepatitis viruses-associated liver diseases:a literature review显示文摘The secosteroid hormone vitamin D has, in addition to its effects in bone metabolism also functions in the modulation of immune responses against infectious agents and in inhibiting tumorigenesis. Thus, deficiency of vitamin D is associated with several malignancies, but also with a plethora of infectious diseases. Among other communicable diseases, vitamin D deficiency is involved in the pathogenesis of chronic liver diseases caused by hepatitis B and C viruses(HBV, HCV) and high prevalence of vitamin D deficiency with serum levels below 20 mg/mL in patients with HBV and HCV infection are found worldwide. Several studies have assessed the effects of vitamin D supplementation on the sustained virological response(SVR) to interferon(IFN) plus ribavirin(RBV) therapy in HBV and HCV infection. In these studies, inconsistent results were reported. This review addresses general aspects of vitamin D deficiency and, in particular, the significance of vitamin D hypovitaminosis in the outcome of HBVand HCV-related chronic liver diseases. Furthermore,current literature was reviewed in order to understand the effects of vitamin D supplementation in combination with IFN-based therapy on the virological response in HBV and HCV infected patients. | Nghiem Xuan Hoan Hoang Van Tong Le Huu Song Christian G Meyer Thirumalaisamy P Velavan | 2018 | World Journal of Gastroenterology2018，24，4： | 9 |
| 4 | Genetic variants of interferon regulatory factor 5 associated with chronic hepatitis B infection显示文摘AIM To investigate possible effects of IRF5 polymorphisms in the 3' UTR region of the IFR5 locus on susceptibilityto hepatitis B virus(HBV) infection and progression of liver diseases among clinically classified Vietnamese patients.METHODS Four IFR5 SNPs(rs13242262 A/T, rs77416878 C/T, rs10488630 A/G, and rs2280714 T/C) were genotyped in clinically classified HBV patients [chronic hepatitis B(CHB). n = 99; liver cirrhosis(LC), n = 131; hepatocellular carcinoma(HCC), n = 149] and in 242 healthy controls by direct sequencing and Taq Man realtime PCR assays. RESULTS Comparing patients and controls, no significant association was observed for the four IFR5 variants. However, the alleles rs13242262 T and rs10488630 G contributed to an increased risk of liver cirrhosis(LC vs CHB: OR = 1.5, 95%CI: 1.1-2.3, adjusted P = 0.04; LC vs CHB: OR = 1.7, 95%CI: 1.1-2.6, adjusted P = 0.019). Haplotype IRF5*TCGT constructed from 4 SNPs was observed frequently in LC compared to CHB patients(OR = 2.1, 95%CI: 1.2-3.3, adjusted P = 0.008). Haplotype IRF5*TCAT occurred rather among CHB patients than in the other HBV patient groups(LC vs CHB: OR = 0.4, 95%CI: 0.2-0.8, adjusted P = 0.03; HCC vs CHB: OR = 0.3, 95%CI: 0.15-0.7, adjusted P = 0.003). The IRF5*TCAT haplotype was also associated with increased levels of ALT, AST and bilirubin. CONCLUSION Our study shows that IFR5 variants may contribute as a host factor in determining the pathogenesis in chronic HBV infections. | Bui Tien Sy Nghiem Xuan Hoan Hoang Van Tong Christian G Meyer Nguyen Linh Toan Le Huu Song Claus-Thomas Bock Thirumalaisamy P Velavan | 2018 | World Journal of Gastroenterology2018，24，2： | 9 |
| 5 | Graphene-based catalysts for electrochemical carbon dioxide reduction显示文摘Electrochemical carbon dioxide(CO2)reduction is considered to be an efficient strategy to produce usable fuels and overcome the concerns regarding global warming.For this purpose,an efficient,earth abundant,and a low cost catalyst has to be designed.It has been found that graphene-based materials could be promising candidates for CO2 conversion because of their unique physical,mechanical,and electronic properties.In addition,the surface of graphenebased materials can be modified by using different strategies,including doping,defect engineering,producing composite structures,and wrapping shapes.In this review,the fundamentals of electrochemical CO2 reduction and recent progress of graphene-based catalysts are investigated.Furthermore,recent studies on graphene-based materials for CO2 reduction are summarized. | Amirhossein Hasani Mahider Asmare Teklagne Ha Huu Do Sung Hyun Hong Quyet Van Le Sang Hyun Ahn Soo Young Kim | 2020 | Carbon Energy2020，2，2： | 7 |
| 6 | Occurrence of emerging flame retardants from e-waste recycling activities in the northern part of Vietnam显示文摘This study investigated the contamination status of 21 emerging flame retardants(FRs)in soils(n=32)and river sediments(n=8)from an e-waste recycling(EWR)site in the northern part of Vietnam.Among analyzed FRs,higher levels of decabromodiphenyl ethane(DBDPE)(NDe4200 ng/g dw),1,2-bis-(2,4,6-tribromophenoxy)ethane(BTBPE)(NDe350 ng/g dw)and Dechlorane Plus isomers(DPs)(NDe65 ng/g dw)were found in soils near EWR workshops and open burning places.The highest concentrations of DBDPE(20 ng/g dw),BTBPE(5.7 ng/g dw)and DPs(6.7 ng/g dw)were also detected in sediments collected from the middle of the EWR site.The levels decreased concomitantly with increasing distance from the EWR site.These results indicate that these FRs were released to the surrounding environment from improper recycling activities,such as manual dismantling of devices and open burning of e-wastes.Moreover,the estimated daily intakes of those FRs via soil ingestion were approximately ten times higher for children than adults.To our knowledge,this is a first comprehensive study on characterization of soil and sediment contamination by a series of emerging FRs at an EWR site in Vietnam. | Masayuki Someya Go Suzuki Alin C.Ionas Nguyen Minh Tue Fuchao Xu Hidenori Matsukami Adrian Covaci Le Huu Tuyen Pham Hung Viet Shin Takahashi Shinsuke Tanabe Hidetaka Takigami | 2016 | Emerging Contaminants2016，2，2： | 5 |

| 11 | STABILITY ANALYSIS OF A COMPUTER VIRUS PROPAGATION MODEL WITH ANTIDOTE IN VULNERABLE SYSTEM显示文摘We study a proposed model describing the propagation of computer virus in the network with antidote in vulnerable system. Mathematical analysis shows that dynamics of the spread of computer viruses is determined by the threshold R_0. If R_0 ≤ 1, the virusfree equilibrium is globally asymptotically stable, and if R_0 > 1, the endemic equilibrium is globally asymptotically stable. Lyapunov functional method as well as geometric approach are used for proving the global stability of equilibria. A numerical investigation is carried out to confirm the analytical results. Through parameter analysis, some effective strategies for eliminating viruses are suggested. | Nguyen Huu KHANH Nguyen Bich HUY | 2016 | Acta Mathematica Scientia2016，36，1： | 4 |
| 12 | Univector field method-based multi-agent navigation for pursuit problem in obstacle environments显示文摘The pursuit problem is a well-known problem in computer science. In this problem, a group of predator agents attempt to capture a prey agent in an environment with various obstacle types, partial observation, and an infinite grid-world. Predator agents are applied algorithms that use the univector field method to reach the prey agent, strategies for avoiding obstacles and strategies for cooperation between predator agents. Obstacle avoidance strategies are generalized and presented through strategies called hitting and following boundary(HFB); trapped and following shortest path(TFSP); and predicted and following shortest path(PFSP). In terms of cooperation, cooperation strategies are employed to more quickly reach and capture the prey agent. Experimental results are shown to illustrate the efficiency of the method in the pursuit problem. | Le Pham Tuyen Hoang Huu Viet Sang Hyeok An Seung Gwan Lee Dong-Han Kim Tae Choong Chung | 2017 | Journal of Central South University2017，24，4： | 3 |
| 13 | 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 |

| 15 | The influence of aggregation of latex particles on membrane fouling attachments&ultrafiltration performance in ultrafiltration of latex contaminated water and wastewater显示文摘The goal of the present study was to investigate the influence of latex particle aggregation on membrane fouling attachments and the ultrafiltration performance of simulated latex effluent using Cetyltrimethyl Ammonium Bromide(CTAB) as a cationic surfactant. Hydrophilic polysulfone and ultrafilic flat heterogeneous membranes, with molecular weight cut off(MWCO) of 60,000 and 100,000, respectively, as well as hydrophobic polyvinylidene difluoride with MWCO of 100,000, were used under a constant flow rate and cross-flow mode in ultrafiltration of latex solution. In addition, a polycarbonate flat membrane with uniform pore size of 0.05 μm was likewise used during the experiment. The effects of CTAB on the latex particle size distribution were investigated at various concentrations, different treatment times, and diverse agitation duration times. The effects of CTAB on the zeta potential of membrane surfaces and latex particles were also investigated. The data obtained indicate that the particle size distribution of treated latex effluent experienced significant shifts in the peaks toward a larger size range caused by the aggregation of particles. As a result, the mass of fouling contributing to pore blocking and the irreversible fouling were noticeably reduced. The optimum results occurred in the instance when CTAB was added at the critical micelle concentration of 0.36 g/L, for the duration of 10 min and with minimal agitation. Notably, a higher stirring rate had an overall negative effect on the membrane fouling minimization. | Amira Abdelrasoul Huu Doan Ali Lohi Chil-Hung Cheng | 2017 | Journal of Environmental Sciences2017，29，2： | 3 |
| 16 | Investigation and assessment of micropollutants and associated biological effects in wastewater treatment processes显示文摘Currently,the wastewater treatment plants(WWTPs)attempt to achieve the shifting from general pollution parameters control to reduction of organic micropollutants discharge.However,they have not been able to satisfy the increasing ecological safety needs.In this study,the removal of micropollutants was investigated,and the ecological safety was assessed for a local WWTP.Although the total concentration of 31 micropollutants detected was reduced by 83%using the traditional biological treatment processes,the results did not reflect chemicals that had poor removal efficiencies and low concentrations.Of the five categories of micropollutants,herbicides,insecticides,and bactericides were difficult to remove,pharmaceuticals and UV filters were effectively eliminated.The specific photosynthesis inhibition effect and non-specific bioluminescence inhibition effect from wastewater were detected and evaluated using hazardous concentration where 5%of aquatic organisms are affected.The photosynthesis inhibition effect from wastewater in the WWTP was negligible,even the untreated raw wastewater.However,the bioluminescence inhibition effect from wastewater which was defined as the priority biological effect,posed potential ecological risk.To decrease non-specific biological effects,especially of macromolecular dissolved organic matter,overall pollutant reduction strategy is necessary.Meanwhile,the ozonation process was used to further decrease the bioluminescence inhibition effects from the secondary effluent;≥0.34 g O 3/g DOC of ozone dose was recommended for micropollutants elimination control and ecological safety. | Xiaoyan Y.Ma Ke Dong Lei Tang Yongkun Wang Xiaochang C.Wang Huu Hao Ngo Rong Chen Na Wang | 2020 | Journal of Environmental Sciences2020，32，8： | 3 |
| 17 | Biomass accumulation of Panax vietnamensis in cell suspension cultures varies with addition of plant growth regulators and organic additives显示文摘Objective: To evaluate the impact of plant growth regulators including kinetin(KN),benzyl adenine and naphthalene acetic acid, yeast extract and casein hydrolyzate on biomass accumulation of Vietnamese ginseng Panax vietnamensis(P. vietnamensis) in cell suspension culture.Methods: Cell suspension cultures were established from friable calluses derived from leaves and petioles of 3-year-old in-vitro P. vietnamensis plants. The cell suspension cultures were grown in Murashige and Skoog basal media supplemented with various concentrations of KN, benzyl adenine, naphthalene acetic acid, and yeast extract and casein hydrolyzate.Results: All tested factors generated an increase in the cell biomass of P. vietnamensis in suspension culture, but the impact of each varies depended on the factor type, concentration, and incubation period. Addition of 2.0 mg/L KN resulted in the largest biomass increase after 24 d,(57.0 ± 0.9) and(3.1 ± 0.1) mg/m L fresh and dry weight, respectively,whereas addition of benzyl adenine or naphthalene acetic acid produced optimum levels of Panax cell biomass at 1.0 and 1.5 mg/L, respectively. Addition of the elicitor yeast extract led to a 1.4–2.4 fold increase in biomass of P. vietnamensis, while addition of casein hydrolyzate enhanced biomass accumulation 1.8–2.6 fold.Conclusions: The addition of each factor causes significant changes in biomass accumulation of P. vietnamensis. The largest biomass accumulation is from cultures grown in MS media containing 2.0 mg/L KN for 24 d. The outcome of the present study provides new insights into the optimal suspension culture conditions for studies on the in vitro cell biomass production of P. vietnamensis. | Tuan Tran Trong Dieu-Hien Truong Hoang Chinh Nguyen Dieu-Thai Tran Huyen-Trang Nguyen Thi Giap Do Dang Ho Nguyen Huu | 2017 | Asian Pacific Journal of Tropical Medicine2017，10，9： | 2 |
