| 1 | 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 |

| 3 | Structural and luminescent properties of (Eu,Tb) PO_4·H_2O nanorods/nanowires prepared by microwave technique显示文摘Nanowires/nanorods of europium/terbium orthophosphate monohydrate with Eu3+ concentration of 6,11,and 20 at.% were prepared by microwave synthesis method.The effects of Eu3+ doping concentration on structure,morphology and optical properties of nanoma-terials were also investigated.The results showed that,for all studied Eu3+ doping concentrations,a single-crystalline phase of rhabdo-phane-type(Eu,Tb) PO4·H2O nanowires/nanorods was obtained by using microwave heating of an aqueous solution of terbium(III) nitrate,europium(III) nitrate and NH4H2PO4 with pH=2.The length and width of these nanowires/nanorods ranged from 150 to 300 nm and from 10 to 50 nm,respectively.The evidence of energy transfer from Tb3+ to Eu3+ due to the energy overlap between the donor Tb3+ and the acceptor Eu3+ was observed obviously via a significant enhancement in the luminescent intensity of Eu3+. | Nguyen Thanh Huong Nguyen Duc Van Dinh Manh Tien Do Khanh Tung Nguyen Thanh Binh Tran Kim Anh Le Quoc Minh | 2011 | Journal of Rare Earths2011，29，12： | 2 |
| 4 | Upconversion luminescence of Gd2O3:Er3+and Gd2O3:Er3+/silica nanophosphors fabricated by EDTA combustion method显示文摘Gd2O3:Er^3+nanophosphors were fabricated by the combustion method in presence of Na2 ethylene diamine tetra acetic acid(EDTA-Na2)as fuel at not high temperature(≤350℃)within a very short time of 5 min.The added concentration of Er^3+ions in Gd2O3 matrix was changed from 0.5 mol%to 5.0 mol%.The X-ray diffraction pattern of samples indicates the monoclinic structure of Gd2O3:Er^3+.The morphology and chemical composition analysis of the Gd2O3:Er^3+samples are characterized by a field emission scanning electron microscope(FESEM)and a Fourier-transform infrared spectrometer(FTIR).The photoluminescence(PL),photo luminescence excitation(PLE)and upconversion(UC)at room temperature of the prepared materials with different concentrations of Er^3+were investigated.The PL of Gd2O3:Er^3+nanomaterials are shown in visible at 545,594,623,648,688 nm under excitation at 275 nm.The emission bands from transitions of Er^3+from 2P3/2 to 4F9/2 are observed,UC luminescent spectra of the Gd2O3:Er^3+/silica nanocomposites under 976 nm excitation show the bands at 548 and 670 nm.The influence of excitation power at 980 nm for transitions were measured and calculated.The results indicate that the upconversion process of Gd2O3:Er^3+/silica is two photons absorption mechanism.The low temperature dependence of UC luminescent intensities of the main bands of Gd2O3:Er^3+was investigated towards development of a nanotemperature sensor in the range of 10-300 K. | Le Quoc Minh Tran Kim Anh Nguyen Duy Hung Pham Thi Minh Chau Nguyen Thi Quy Hai Ho Van Tuyen Vu Thi Thai Ha Vu Duc Tu Wieslaw Strek | 2019 | Journal of Rare Earths2019，37，11： | 2 |
| 5 | Ecoregional variations of aboveground biomass and stand structure in evergreen broadleaved forests显示文摘Biotic and abiotic factors control aboveground biomass(AGB)and the structure of forest ecosystems.This study analyses the variation of AGB and stand structure of evergreen broadleaved forests among six ecoregions of Vietnam.A data set of 1731-ha plots from 52 locations in undisturbed old-growth forests was developed.The results indicate that basal area and AGB are closely correlated with annual precipitation,but not with annual temperature,evaporation or hours of sunshine.Basal area and AGB are positively correlated with trees>30 cm DBH.Most areas surveyed(52.6%)in these old-growth forests had AGB of 100–200 Mg ha^-1;5.2%had AGB of 400–500 Mg ha^-1,and 0.6%had AGB of>800 Mg ha^-1.Seventy percent of the areas surveyed had stand densities of 300–600 ind.ha^-1,and 64%had basal areas of 20–40 m^2 ha^-1.Precipitation is an important factor influencing the AGB of old-growth,evergreen broadleaved forests in Vietnam.Disturbances causing the loss of large-diameter trees(e.g.,>100 cm DBH)affects AGB but may not seriously affect stand density. | Tran Van Do Mamoru Yamamoto Osamu Kozan Vo Dai Hai Phung Dinh Trung Nguyen Toan Thang Lai Thanh Hai Vu Thanh Nam Trieu Thai Hung Hoang Van Thang Tran Duc Manh Cao Chi Khiem Vu Tien Lam Nguyen Quang Hung Tran Hoang Quy Pham Quang Tuyen Trinh Ngoc Bon Nguyen Thi Thu Phuong Ninh Viet Khuong Nguyen Van Tuan Dang Thi Hai Ha Tran Hai Long Dang Van Thuyet Dang Thinh Trieu Nguyen Van Thinh Tran Anh Hai Duong Quang Trung Nguyen Van Bich Dinh Hai Dang Pham Tien Dung Nguyen Huy Hoang Le Thi Hanh Phan Minh Quang Nguyen Thi Thuy Huong Hoang Thanh Son Nguyen Thanh Son Nguyen Thi Van Anh Nguyen Thi Hoai Anh Pham Dinh Sam Hoang Thi Nhung Hoang Van Thanh Nguyen Huu Thinh Tran Hong Van Ho Trung Luong Bui Kieu Hung | 2020 | Journal of Forestry Research2020，31，5： | 1 |

| 9 | Antibiotic usage in surgical sperm retrievals among IVF centers显示文摘Surgical sperm retrieval(SSR)is currently one of the most common procedures in in vitro fertilization(IVF).However,a gap between the guidelines and routine clinical practice regarding antibiotic use in sSR,which might lead to antibiotic resistance,is a challenging problem worldwide.A cross-sectional survey was conducted from May 1,2021,to July 15,2021,to investigate antibiotic usage by medical professionals when performing SSR in IVF centers in Vietnam.The confidential questionnaire comprised 12 items,including characteristics of the study population,awareness of antimicrobial resistance,attitude toward prescribing antibiotics,and current practice of prescribing antibiotics when performing SSR.Surveys were completed by 30 of 45 registered IVF centers(66.7%).Among 67 physicians working at those centers,the age and work-experience years(mean±standard deviation[s.d.])were 38.6±6.6 years and 11.2±7.0 years,respectively.Over 60%of them held a degree in Obstetrics and Gynecology,and over four-fifths were men.Most respondents'often/very often/always'raised awareness of antimicrobial resistance to their patients(83.3%),but only half of them'often/occasionally'prescribed antibiotics to patients with SSR in cases where the prescription would be optional.About one-tenth of respondents followed the recommendation from the American Urological Association using'prophylaxis only'for SSR patients.For more invasive SSR,physicians tended to prescribe more complicated and sometimes inappropriate regimens.In conclusion,antibiotic usage in SSR was not always appropriate among IVF centers.Further studies may define specific recommendations for regimens,intervention strategies,and programs to promote appropriate antibiotic use for SSR patients among IVF specialists. | Le Dang Khoa Ngo Dinh Trieu Vy Nguyen Minh Tai Loc Le Duc Thang Dang Tuan Anh Nguyen Phuc Hieu Giang Huynh Nhu Nguyen Dinh Tao Le Hoang David J Handelsman | 2022 | Asian Journal of Andrology2022，24，6： | 0 |
| 10 | Cholecystitis-an uncommon complication following thoracic duct embolization for chylothorax: A case report显示文摘BACKGROUND Chylothorax is an uncommon condition in which chyle leaks into the pleural cavity,and biliary peritonitis is a rare complication of thoracic duct embolization in clinical practice.CASE SUMMARY We describe the case of a 50-year-old woman who presented with chylothorax and underwent thoracic duct embolization using a coil and a mixture of histoacryl glue and lipiodol.The patient developed upper abdominal pain and fever after the intervention.She was diagnosed with biliary peritonitis and treated with cholecystectomy at Hanoi Medical University Hospital.CONCLUSION Although thoracic duct embolization is considered a safe and minimally invasive procedure,it is not without risk.Following thoracic duct embolization,severe or persistent abdominal pain should be explored utilizing imaging data and laboratory results to determine problems as soon as possible. | Le Viet Dung Ma Mai Hien Thieu-Thi Tra My Doan Tien Luu Le Tuan Linh Nguyen Minh Duc | 2022 | World Journal of Clinical Cases2022，10，24： | 0 |

| 12 | Investigation.of human visual cortex responses to flickering light using functional near infrared spectroscopy and constrained ICA显示文摘The human visual sensitivity to the flickering light has been under investigation for decades.The finding of research in this area can contribute to the understanding of human visual system mechanism and visual disorders,and establishing diagnosis and treatment of diseases.The aim of this study is to investigate the ffects of the flickering light to the visual cortex by monitoring the hemodynamic responses of the brain with the functional near infrared spectrosoopy(ENIRS)method.Since the acquired fNIRS signals are afected by physiological factors and measurement artifacts,constrained independent component analysis(eICA)was applied to extract the actual fNIRS responses from the obtained data.The experimental results revealed significant changes(p<0.0001)of the hemodynamic responses of the visual cortex.from the baseline when the flickering stimulation was activated.With the uses of cICA,the contrast to noise ratio(CNR),reflecting the contrast of hemodynamic concentration between rest and task,became larger.This indicated the improvement of the NIRS signals when the noise was eliminated.In subsequent studies,statistical analysis was used to infer the correlation between the NIRS signals and the visual stimulus.We found that there was a slight decrease of the oxygenated hemoglobin con-centration(about 5.69%)over four frequencies when the modulation increased.However,the variations of oxy and deoxy-hemoglobin were not statistically significant. | Nguyen Duc Thang Vo Van Toi Le Giang Tran Nguyen Huynh Minh Tam Lan Anh Trinh | 2014 | Journal of Innovative Optical Health Sciences2014，7，6： | 0 |
| 13 | Prevalence, risk factors, and BRAF mutation of colorectal sessile serrated lesions among Vietnamese patients显示文摘BACKGROUND Sessile serrated lesions(SSLs)are considered precancerous colorectal lesions that should be detected and removed to prevent colorectal cancer.Previous studies in Vietnam mainly investigated the adenoma pathway,with limited data on the serrated pathway.AIM To evaluate the prevalence,risk factors,and BRAF mutations of SSLs in the Vietnamese population.METHODS This is a cross-sectional study conducted on patients with lower gastrointestinal symptoms who underwent colonoscopy at a tertiary hospital in Vietnam.SSLs were diagnosed on histopathology according to the 2019 World Health Organi-zation classification.BRAF mutation analysis was performed using the Sanger DNA sequencing method.The multivariate logistic regression model was used to determine SSL-associated factors.RESULTS There were 2489 patients,with a mean age of 52.1±13.1 and a female-to-male ratio of 1:1.1.The prevalence of SSLs was 4.2%[95%confidence interval(CI):3.5-5.1].In the multivariate analysis,factors significantly associated with SSLs were age≥40[odds ratio(OR):3.303;95%CI:1.607-6.790],male sex(OR:2.032;95%CI:1.204-3.429),diabetes mellitus(OR:2.721;95%CI:1.551-4.772),and hypertension(OR:1.650,95%CI:1.045-2.605).The rate of BRAF mutations in SSLs was 35.5%.CONCLUSION The prevalence of SSLs was 4.2%.BRAF mutations were present in one-third of SSLs.Significant risk factors for SSLs included age≥40,male sex,diabetes mellitus,and hypertension. | Nhu Thi Hanh Vu Huy Minh Le Diem Thi-Ngoc Vo Hoang Anh Vu Nhan Quang Le Dung Dang Quy Ho Duc Trong Quach | 2024 | World Journal of Clinical Oncology2024，15，2： | 0 |

| 15 | A study implementing real-time PCR to identify Strongyloides species of third-stage larvae in human stool samples from Southern Vietnam显示文摘Background:Strongyloidiasis,a neglected disease caused by intestinal nematodes of the genus,is endemic to tropical and subtropical areas such as Vietnam.Morphological methods only identify the genus,while DNA-molecular techniques are susceptible in Strongyloides spp.detection.The study aims to determine the prevalence of dominant Strongyloides species among the population in Duc Hoa district,Long An,Vietnam.Methods:A cross-sectional study used 1190 stool specimens collected from July 2017 to November 2018.All samples were transported within 2 h,stored at 2-8℃,and processed within 48 h for microscopy smear and culture at the Laboratory of Medical Parasitology,Pham Ngoc Thach University of Medicine(PNT).Then all positive samples with the above 2 methods were verified by real-time PCR technique.Real-time PCR amplification was conducted at the Laboratory of Molecular Biology,PNT.Results:Direct microscopy and modified Harada-Mori culture detected Strongyloides spp.larvae in 79/1190 sam-ples(6.6%).About 94.2%of the DNA samples were Strongyloides stercoralis,2.9%were co-infections with Strongy-loides ratti and S.stercoralis,and 2.9%were patients with S.ratti.The identity of 12/14 sequences was confirmed as S.stercoralis with a high level of similarity(91.3%-100%)and over 98%for S.ratti.Conclusion:DNA-molecular techniques and sequence analysis are highly suitable for identifying Strongyloides species isolated from stool samples.It is remarkable evidence of the presence of zoonosis S.ratti disease in human,not just the known S.stercoralis.It is likely to result in a certain proportion of people being infected by this animal-borne infectious pathogen. | Le Duc Vinh Nguyen Kim Thach Huynh Hong Quang Do Nhu Binh Tran Thi Duc Hanh Nguyen Minh Toàn Nguyen Trung Tuyen Nguyen Thu Huong | 2023 | Infectious Medicine2023，2，3： | 0 |
| 16 | Effects of low energy (160 keV) X-ray on microbial inactivation,sprouting inhibition and genetic variation in potato显示文摘The effects of low energy X-ray irradiation on microbial inactivation,sprouting inhibition and genetic variation were surveyed.There was an inverse correlation between the exposure dose in range of 0 Gy–5000 Gy and the survival rate of microorganisms.The dose of 1000 Gy seemed to be suitable for inactivation of microorganisms because the respective survival rate is relatively low (0.59%).Dose rate of 13.87 Gy/min was the most appropriate to inactivate the microorganisms,with the survival rate of 0.37%.Applying the irradiation dose of 1000 Gy and dose rate of 13.87 Gy/min,there was a significant sprouting inhibition of irradiated potatoes compared to the control for six months storage.The effect of irradiation dose (100–1200 Gy) and dose rate (8.63–19.62 Gy/min) on genetic variation of the irradiated samples was assessed by DNA fingerprints induced from using three molecular techniques including Random Amplified Polymorphic DNA (RAPD),Start Codon Targeted Polymorphism (SCoT) and CAAT box – derived polymorphism (CBDP).At the irradiation dose of 1000 Gy and dose rate of 13.87 Gy/min,the level of genetic variation was relatively low (4.85%).Thus,this treatment is a suitable condition of irradiation for potato treatment with the purpose of preservation. | Nguyen An Son Nguyen Thi Nguyet Ha Nguyen Thi Minh Sang Le Doan Dinh Duc Le Ngoc Trieu | 2022 | Food Bioscience2022，47，3： | 0 |

| 18 | Gold nanorods conjugated upconversion nanoparticles nanocomposites for simultaneous bioimaging,local temperature sensing and photothermal therapy of OML-1 oral cancer cells显示文摘The major challenge in photothermal therapy(PTT)is to develop nanocomposites that simultaneously exhibit bioimaging and PTT under a single near-infrared(NIR)irradiation with high therapeutic efficiency.Herein,we present a multifunctional nanocomposite synthesized by linking NaYF_(4):Yb^(3+),Er^(3+)upconversion nanoparticles(UCNPs)with gold nanorods(AuNR)to exhibit fluorescence label-ing,local temperature sensing and photothermal functions simul-taneously with a single NIR laser excitation.The AuNR-NaYF_(4):Yb^(3+),Er^(3+)nanocomposite particles displayed better photothermal prop-erties compared with pure AuNRs or a blend of AuNRs and NaYF_(4):Yb^(3+),Er^(3+)UCNPs.The temperature-dependent upconversion lumi-nescence(UCL)property was used to determine local temperature at the nanocomposite particles,which is useful for selecting appro-priate irradiation dosage for PTT.The therapeutic performance of the nanocomposites in PTT for OML-1 oral cancer cells was deter-mined.For cell labeling,we successfully labeled streptavidin-linked nanocomposite particles on the surface of OML-1 oral cancer using anti-human epidermal growth factor receptor 2(anti-Her2)anti-body.Finally,the nanocomposite particles caused exceptional destruction of cancer cells up to 70%dead cells under 976 nm laser irradiation for only one min at 0.3 W/cm^(2)which is below the maximal permissible exposure of human skin. | Duc Tu Vu Thanh Thu Vu-Le Van Nghia Nguyen Quoc Minh Le Churng-Ren Chris Wang Lai-Kwan Chau Tzyy-Schiuan Yang Michael WYChan Cheng-I Lee Chu-Chi Ting Jiunn-Yuan Lin Hung-Chih Kan Chia Chen Hsu | 2021 | International Journal of Smart and Nano Materials2021，12，1： | 0 |
