| 1 | 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 |
| 2 | Analysis of monomeric and oligomeric organophosphorus flame retardants in fish muscle tissues using liquid chromatographyeelectrospray ionization tandem mass spectrometry:Application to Nile tilapia(Oreochromis niloticus)from an e-waste processing area in northern Vietnam显示文摘Using electrospray ionization tandem mass spectrometry combined with liquid chromatography(LC),a novel analytical method was developed to quantify eight monomeric organophosphorus flame retardants(m-PFRs)and three oligomeric organophosphorus flame retardants(o-PFRs)in fish muscle samples.The optimization and validation experiments indicate that the developed method can determine accurately the concentrations of analytes in fish muscle samples.The recoveries of analytes in fish muscle samples were in the range of 74-105%.The coefficients of variation of the concentrations of analytes in fish muscle samples were 0.6-8.9%.The concentrations of analytes in procedural blanks were below the limit of quantification(LOQ)values.Furthermore,the developed method was applied to the analysis of m-PFRs and o-PFRs in the muscle samples of tilapias collected from an electronic waste(ewaste)processing area in northern Vietnam.The concentrations of m-PFRs such as tris(2-chloroethyl)phosphate(TCEP),tris(2-chloroisopropyl)phosphate(TCIPP),and triphenyl phosphate(TPHP)were dominant among the investigated m-PFRs.The respective concentrations of TCEP,TCIPP,and TPHP were up to 160,300,and 230 ng g^-1 lipid weight,respectively,whereas those of o-PFRs were up to 10 ng g^-1 lipid weight.The results of this study indicate lower accumulation potential of o-PFRs compared with m-PFRs for the first time. | Hidenori Matsukami Go Suzuki Nguyen Minh Tue Le Huu Tuyen Pham Hung Viet Shin Takahashi Shinsuke Tanabe Hidetaka Takigami | 2016 | Emerging Contaminants2016,2,2: | 5 |
| 3 | Synthesis and characterization of NaYF4:Yb3+,Er3+@silica-N=folic acid nanocomplex for bioimaginable detecting MCF-7 breast cancer cells显示文摘Upconversion nanophosphors are new promising nanomaterials to be used as biolabels for detection and imaging of cancer cells.These nanophosphors absorb long-wavelength excitation radiation in the infrared or near infrared region and emit shorter wavelength,higher energy radiation from ultraviolet to infrared.In this paper,we studied the hydrothermal method and optical properties of the functionalized NaYF4:Yb^3+,Er^3+for biomedical application.After synthesis,these NaYF4:Yb^3+,Er^3+nanophosphors were functionalized with aminosilanes and folic acid.Folic acid binds to the folate receptor on the surface of MCF-7 breast cancer cells and this binding promotes internalization of the nanophosphors via endocytosis.The sizes of the functionalized NaYF4:Yb^3+,Er^3+@silica-N=FA(folic acid)nanophosphors can be controlled with length of the rod about 300-800 nm and diameter of the rod about 100-200 nm.Phase structure of NaYF4:Yb^3+,Er^3+is in hexagonal crystal system.The photo luminescence(PL)spectra of the functionalized NaYF4:Yb^3+,Er^3+@silica-N=FA nanophosphors were measured.These nanophosphors emit in red color with the strongest band at 650 nm under 980 nm excitation.This result can provide NaYF4:Er^3+,Yb^3+@silica-N=FA complex for developing fluorescence label and image tool in cancer biology and medicine. | Ha Thi Phuong Tran Thu Huong Le Thi Vinh Hoang Thi Khuyen Do Thi Thao Nguyen Thanh Huong Pham Thi Lien Le Quoc Minh | 2019 | Journal of Rare Earths2019,37,11: | 5 |

| 6 | A sand production prediction model for weak sandstone reservoir in Kazakhstan显示文摘Weakly consolidated reservoirs are prone to sand production problem,which can lead to equipment damages and environmental issues.The conditions for sand production depend on stresses and properties of rock and fluid.Accurate sand volume estimation is,however,still a challenging issue,especially for reservoirs in weak formations.The weak reservoirs containing viscous or heavy oil are mainly discovered in shallow depths in Kazakhstan,with moderate temperature and pressure.Many prediction models developed for open-hole completions where the reservoir materials usually possess certain strength are not applicable for the local reservoirs where the materials are significantly weaker even if casing is used to support the wellbore with oil produced through the perforation tunnels.In this context,a prediction model was proposed where the volume of the produced sand was estimated as the volume of the plastic zone of the failed materials surrounding the perforation tunnels.The model assumes an evolving truncated conical shape for the damage zone and takes into account stress distributions and shear failure in this zone.Then,the proposed model was used to estimate sand volumes in 20 wells during oil production with sequential increase of flow rates.The predictions match well with the measured sand volumes in a local oil field.Finally,a sensitivity analysis was conducted on the model performance.It shows that the permeability of the plastic zone was the most significant controlling factor in the prediction results. | Ainash Shabdirova Nguyen Hop Minh Yong Zhao | 2019 | Journal of Rock Mechanics and Geotechnical Engineering2019,11,4: | 5 |
| 7 | 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 |
| 8 | 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 |
| 9 | 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 |

| 14 | Effects of transcranial ultrasound stimulation pulsed at 40 Hz on Aβplaques and brain rhythms in 5×FAD mice显示文摘Background:Alzheimer's disease(AD)is the most common cause of dementia,and is characterized by amyloid-β(Aβ)plaques and tauopathy.Reducing Aβhas been considered a major AD treatment strategy in pharmacological and non-pharmacological approaches.Impairment of gamma oscillations,which play an important role in perception and cognitive function,has been shown in mouse AD models and human patients.Recently,the therapeutic effect of gamma entrainment in AD mouse models has been reported.Given that ultrasound is an emerging neuromodulation modality,we investigated the effect of ultrasound stimulation pulsed at gamma frequency(40 Hz)in an AD mouse model.Methods:We implanted electroencephalogram(EEG)electrodes and a piezo-ceramic disc ultrasound transducer on the skull surface of 6-month-old 5×FAD and wild-type control mice(n=12 and 6,respectively).Six 5×FAD mice were treated with two-hour ultrasound stimulation at 40 Hz daily for two weeks,and the other six mice received sham treatment.Soluble and insoluble Aβlevels in the brain were measured by enzyme-linked immunosorbent assay.Spontaneous EEG gamma power was computed by wavelet analysis,and the brain connectivity was examined with phase-locking value and cross-frequency phase-amplitude coupling.Results:We found that the total Aβ42 levels,especially insoluble Aβ42;in the treatment group decreased in pre-and infra-limbic cortex(PIL)compared to that of the sham treatment group.A reduction in the number of Aβplaques was also observed in the hippocampus.There was no increase in microbleeding in the transcranial ultrasound stimulation(tUS)group.In addition,the length and number of microglial processes decreased in PIL and hippocampus.Encel-phalographic spontaneous gamma power was increased,and cross-frequency coupling was normalized,implying functional improvement after tUS stimulation.Conclusion:These results suggest that the transcranial ultrasound-based gamma-band entrainment technique can be an effective therapy for AD by reducing the Aβload and improving brain connectivity. | Mincheol Park Gia Minh Hoang Thien Nguyen Eunkyung Lee Hyun Jin Jung Youngshik Choe Moon Hwan Lee Jae Youn Hwang Jae Gwan Kim Tae Kim | 2021 | Translational Neurodegeneration2021,10,4: | 2 |
| 15 | Synthesis and characterization of core/shell structured nanophosphors CePO_4:Tb@LaPO_4 by solvothermal method显示文摘Core/shell structured CePO4:Tb(III) @LaPO4 and CePO4:Tb(III) were successfully synthesized in tris(2-ethylhexyl) phosphate(TEHP) and diethylene glycol(DEG) solvents for comparison of the two techniques in open air and closed reaction vessel.Morphology and crystal structure of the core/shell nanophosphors were determined by using X-ray diffraction(XRD) and transmission electron microscopy(TEM) ,which showed that nanophosphors had diameter of about 5-10 nm with the monoclinic monazite phase.The nanophosphors obtained by close vessel procedure showed smaller size,more homogeneity and pure crystallite.The luminescent measurements were done upon the different excitation wavelengths in ultraviolet region and at room temperature to elucidate the influences of the used solvents and the reaction temperatures.It was found that CePO4:Tb@LaPO4 prepared by the close vessel synthesis showed the intensity of green band of the transfer from 5D4 to 7F5 energy level,which was strongly increased,and the luminescent decay time was 3.2 ms,which was longer than that of naked CePO4:Tb phosphor. | Dinh Xuan Loc Tran Thi Kim Chi Tran Thu Huong Nguyen Vu Tran Kim Anh Wieslaw Strek Le Quoc Minh | 2011 | Journal of Rare Earths2011,29,12: | 2 |
| 16 | Synthesis of cation exchange resin-supported iron and magnesium oxides/hydroxides composite for nitrate removal in water显示文摘In this study,we reported on the concept and practical use of cation exchange resin(CER)for removing anions in water via pretreating the CER with metal salts.The cation exchange resinsupported iron and magnesium oxides/hydroxides composite(FeMg/CER)was synthesized and introduced as a new and potential adsorbent for selective removal of nitrate ion in the water environment.Characteristics of FeMg/CER were determined by techniques such as Fouriertransform infrared spectroscopy,scanning electron microscopy,and Xray diffraction.The results showed that FeMg/CER material had a high nitrate adsorption capacity of 200 mg NO_(3)^()·g^(1)with a fast equilibrium adsorption time of 30 min at pH 5.In addition,it had good durability of at least 10 times of regeneration,which could be applied to practical water and wastewater treatment. | Trung Thanh Nguyen Vu Anh Khoa Tran Le Ba Tran Phuoc Toan Phan Minh Tan Nguyen Long Giang Bach Surapol Padungthon Cong Khiem Ta Nhat Huy Nguyen | 2021 | Chinese Journal of Chemical Engineering2021,34,4: | 2 |
