Background In Viet Nam, tuberculosis (TB) represents a devastating life-event with an exorbitant price tag, partly due to lost income from daily directly observed therapy in public sector care. thus, persons with TB may seek care in the private sector for its flexibility, convenience, and privacy. Our study aimed to measure income changes, costs and catastrophic cost incurrence among TB-affected households in the public and private *** Between October 2020 and March 2022, we conducted 110 longitudinal patient cost interviews, among 50 patients privately treated for TB and 60 TB patients treated by the National TB Program (NTP) in Ha Noi, Hai Phong and Ho Chi Minh City, Viet Nam. Using a local adaptation of the WHO TB patient cost survey tool, participants were interviewed during the intensive phase, continuation phase and post-treatment. We compared income levels, direct and indirect treatment costs, catastrophic costs using Wilcoxon rank-sum and chi-squared tests and associated risk factors between the two cohorts using multivariate *** The pre-treatment median monthly household income was significantly higher in the private sector versus NTP cohort (USD 868 vs USD 578;P=0.010). However, private sector treatment was also significantly costlier (USD 2075 vs USD 1313;P=0.005), driven by direct medical costs which were 4.6 times higher than costs reported by NTP participants (USD 754 vs USD 164;Pthis resulted in no significant difference in catastrophic costs between the two cohorts (Private: 55% vs NTP: 52%;P=0.675). Factors associated with catastrophic cost included being a single-person household [adjusted odds ratio [(aOR=13.71; 95% confidence interval (CI): 1.36–138.14;P=0.026], unemployment during treatment (aOR=10.86; 95%CI: 2.64–44.60;P<0.001) and experiencing TB-related stigma (aOR=37.90; 95%CI: 1.72–831.73;P=0.021).Conclusions Persons with TB in Viet Nam face similarly high risk of catastrophic costs whether treated in the

Objective: To examine the in vitro and in vivo anti-inflammatory effects of the alkaloid enriched extract(ELA) from the roots of Eurycoma longifolia. Methods: The in vitro antiinflammatory effects of ELA were evaluated by examining its inhibitory activities against nitric oxide(NO) production and inducible nitric oxide synthase(iN OS) and cyclooxygenase2(COX-2) expressions in lipopolysaccharide(LPS)-stimulated RAW264.7 cells. The level of NO produced in the culture media was determined by Griess method. The i NOS and COX-2 protein expressions were analyzed by Western blot. The in vivo effect of ELA was evaluated on LPS-induced septic shock in mice model. Mice mortality was monitored for5 days after injection of LPS. The chemical contents of the ELA were determined by using various chromatographic and spectroscopic techniques. Results: The ELA was found to exhibit a significant anti-inflammatory effect in both in vitro and in vivo models. The results demonstrated that ELA dose-dependently inhibited LPS-induced NO production as well as the protein iN OS and COX-2 expressions. In the septic shock model, ELA dose-dependently protected mice from LPS-induced mortality. Further study on the isolated components of ELA indicated that 9,10-dimethoxycanthin-6-one may contribute significantly to the antiinflammatory effects of the extract. Conclusions: These results suggest that ELA exhibits the anti-inflammatory activity via suppression of pro-inflammatory mediators such as NO, iN OS,and COX-2 and protects mice from LPS-induced mortality in septic shock model.

In this study, a novel layer-by-layer polyaniline/graphene （PANi/Gr） structure for electrochemical detec- tion of atrazine was developed. Gr film was synthesized by thermal chemical vapor deposition （CVD） method and transferred onto the PANi-predeposited microelectrode. The properties of PANi/Gr film were thoroughly investigated by high-resolution transmission electron microscopy and Raman techniques. The most attractive feature of this system is a suitable microenvironment, which could provide an amplifi- cation of the conductive signal, thus may contribute to enhancing electron transfer and subsequently improve the sensitivity in electrochemical measurements. With low detection limit （- 43 × 10 -12 g/L）, ac-ceptable stability and good reproducibility, the proposed electrochemical immunosensor could be advantageously extended for multiplexed detection of other agents of environmental pollution.

Soc trang is one of coastal provinces in which rice land is relatively low and therefore under annual threat of saline intrusion and other climatic variabilities. It raises an urgent need to identify various rice varieties which are short-duration, highly adaptive to salinity penetration, floods and aluminium poisonous matters, as well as high productivity and quality. The research applies the GIS （Geo-Information System） and RS （Remote Sensing） techniques to accurately evaluate the adaptability of different salinity-tolerant rice varieties. We have used information from FAO （The Food and Agriculture Organization）, Maplnfo and ArcGIS to map different components separately that are overlapped and mixed together to build different maps indicating the adaptability of different rice varieties to salinity in different locations in Soc trang. We have also identified various factors affecting the productivity of these rice varieties. Then, several salinity-resistent rice varieties have been piloted in different areas to figure out which varieties are most suitable for specific regions.

Sweet potato [Ipomoea batatas （L.） Lam.] is an important food crop in the world as well as in Vietnam. It is well known as a recalcitrant crop for gene transformation and tissue culture because of its genotype dependent in vitro responses. In present study, Agrobacterium-mediated transformation of cry8Db from Bacillus thuringiensis into KB 1 sweet potato variety has been studied. The C58cv strain carrying a pBl 121 backbone which contained cry8Db delta-endotoxin gene regulated under 35 S CaMV prom oter, and the selection marker gene, neomycin phosphotransferase （npt11） gene, was subjected for plant transformation. Callus induced from shoot tips and leaf explants were inoculated and cocultured with A. tumefaciens. The selection occurred during callus producing and plant regenerating steps. A total of 201 transgenic putative plant lines were produced, and 21 transgenic lines were positively confirmed by PCR and finalized by Southern blot. Four putative transgenic lines confirming a single copy of the crySEIb gene were transferred into soil pots in greenhouse. Biological activity evaluation for the insecticidal capacity of these transgenic lines under controlled conditions showed that the level of infestation by sweet potato weevils （Cylasformicarius） in untransformed plants was higher than that of transgenic lines.

Nanorod-like TiO2 (nc-TiO2) and MoO3 (nc-MoO3) films were thermally grown from Ti- and Mo-metallic wafers. Nanohybrid films of N,N’-diphenyl-N,N’-bis(1-naphthyl)(1,1’-biphenyl)-4,4’diamine (NPB)/TiO2 and NPB/MoO3 used as anode/hole transport layer (HTL) heterojunctions in blue organic light emission diodes (OLEDs) were prepared by coating NPB onto the nc-TiO2 and nc-MoO3 and TiO2. Characterization of the nanostructured hybrid layers showed that both the photoluminescent property and current-voltage (I-V) characteristics of the hybrid materials were significantly enhanced in comparison with the standard NPB polymer. The electroluminous efficiency of the hybrid devices was considerably enhanced in comparison with the standard device. this suggests a useful application for fabricating “reverse” OLEDs, where the emission light goes-out through the semitransparent cathode, instead of the indium tin oxide (ITO) anode. For this, the ohmic contacts of conducting wires to metallic electrodes can be made much better than to ITO anodes.
