    Abstract: P. vietnamense O. Gruss & Perner is one of the endemic lady’s slipper orchids in Vietnam that has been known as an endangered species threatened with extinction due to over-collection. To protect P. vietnamense species, In Vitro propagation method needs to be established for producing plantlets that can be introduced back in wild, as well as commercialized. In this study, we examined the effect of basal culture medium, plant growth regulators, and AC on the micropropagation ability of P. vietnamense , which were collected from wild population in Thai Nguyen province, Northeastern Vietnam. We determined that the 0.2% HgCl 2 can be used in within 5 to 10 min for sterilizing axillary buds of P. vietnamense , resulting in 65.55% of disinfected samples. Moreover, the 1/2 MS medium supplemented with 2.0 mg 1 -1 BA and 1.0 mg 1 -1 NAA, which gave about 2.85 shoots/sample, was the most suitable for shoot regeneration and multiplication. In addition, the result also indicated that 0.5 mg 1 -1 NAA and 1.0 g 1 -1 AC gave the best results (88.89%) for root induction and plantlets

    Abstract:  Nghiên cứu được thực hiện nhằm đánh giá tác dụng chống đông của viên hoàn Trân châu ngưu hoàng hoàntrên mô hình gây đông máu bằng lipopolysaccharid ở chuột cống trắng. Chuột được uống thuốc thử liều 0,12 và0,36 viên/kg/ngày trong 7 ngày liên tục. Hai giờ sau khi uống thuốc thử lần cuối cùng, chuột được gây mô hìnhđông máu bằng cách tiêm tĩnh mạch đuôi chuột lipopolysaccharid liều 3 mg/kg. Chuột cống ở các lô nghiên cứuđược lấy máu vào thời điểm 4 giờ sau khi gây mô hình để đánh giá các chỉ số nghiên cứu bao gồm số lượng tiểucầu, nồng độ fibrinogen, thời gian prothrombin (PT), thời gian thromboplastin từng phần hoạt hóa (aPTT). Kếtquả của nghiên cứu cho thấy tác dụng chống đông phụ thuộc liều của Trân châu ngưu hoàng hoàn thể hiện thôngqua việc tăng số lượng tiểu cầu và nồng độ fibrinogen, đồng thời kéo dài PT và aPTT. Như vậy, Trân châu ngưuhoàng hoàn có tác dụng chống đông trên mô hình gây đông máu bằng lipopolysaccharid ở chuột cống trắng.

    Abstract: Flood is a natural disaster that can cause loss of life and damage to property. The objective of this study is to create a flood map of Yen Bai city, where flood occurs regularly during heavy rain and Thao River's water level rises. The study used Mike Flood model based on the connection of 1D and 2D hydrodynamic models. The model parameters were calibrated and validated againts observed water level data of two major flood events in August 2008 and July 2009 which were measured by Bao Ha and Yen Bai hydrological stations, in addition with historical flood survey data in 2008. Flood map was developed corresponding to the alarm levels. The results show that the most affected areas by flood are 4 communes of Au Lau, Hop Minh, Tuy Loc, and Hong Ha wards.

    Abstract: “Tran chau nguu hoang hoan” was prepared from 12 herbal ingredients. So far, the safety of this product, has not been reported yet. Thus, this study aimed to evaluate the acute and subchronic toxicity of “Tran chau nguu hoang hoan” through oral administration in experimental animals. The acute toxicity was determined by the method of Litchfield Wilcoxon in mice at the doses of 2.42 g/kg b.w/day to 6.04 g/kg b.w/day. The subchronic toxicity was evaluated followed the Guideline of WHO and OECD in rats with oral doses of 58.0 mg/kg b.w/day and 174.0 mg/kg b.w/day for 12 consecutive weeks. As a result, in the course of the acute toxicity test, the mice showed no abnormal sign or death. In terms of the subchonic toxicity test, hematological indexes, hepato-renal functions and microscopic images of liver and kidney were unchanged. In conclusion, “Tran chau nguu hoang hoan” does not appear to produce acute and subchronic toxicities in mice and rats.

    Effects of Extracellular Vesicles Secreted by TGFβ-Stimulated Umbilical Cord Mesenchymal Stem Cells on Skin Fibroblasts by Promoting Fibroblast Migration and ECM Protein Production

    Abstract: Umbilical cord-derived mesenchymal stem cells (UCMSCs) have been illustrated for their roles in immunological modulation and tissue regeneration through the secretome. Additionally, culture conditions can trigger the secretion of extracellular vesicles (EVs) into extracellular environments with significant bioactivities. This study aims to investigate the roles of three EV sub-populations released by UCMSCs primed with transforming growth factor β (TGFβ) and their capacity to alter dermal fibroblast functions for skin aging. Results show that three EV sub-populations, including apoptotic bodies (ABs), microvesicles (MVs), and exosomes (EXs), were separated from conditioned media. These three EVs carried growth factors, such as FGF-2, HGF, and VEGF-A, and did not express noticeable effects on fibroblast proliferation and migration. Only EX from TGFβ-stimulated UCMSCs exhibited a better capacity to promote fibroblasts migrating to close scratched wounds than EX from UCMSCs cultured in the normal condition from 24 h to 52 h. Additionally, mRNA levels of ECM genes (COL I, COL III, Elastin, HAS II, and HAS III) were detected with lower levels in fibroblasts treated with EVs from normal UCMSCs or TGFβ-stimulated UCMSCs compared to EV-depleted condition. On the contrary, the protein levels of total collagen and elastin released by fibroblasts were greater in the cell groups treated with EVs compared to EV-depleted conditions; particularly elastin associated with TGFβ-stimulated UCMSCs. These data indicate the potential roles of EVs from UCMSCs in protecting skin from aging by promoting ECM protein production.

    Abstract: In this paper, the tracking control scheme is presented using the framework of finite-time sliding mode control (SMC) law and high-gain observer for disturbed/uncertain multi-motor driving systems under the consideration multi-output systems. The convergence time of sliding mode control is estimated in connection with linear matrix inequalities (LMIs). The input state stability (ISS) of proposed controller was analyzed by Lyapunov stability theory. Finally, the extensive simulation results are given to validate the advantages of proposed control design.

    Abstract: Objectives: The incidence of posttraumatic stress disorder (PTSD) has increased, particularly among individuals who have recovered from coronavirus disease 2019 (COVID-19) infection. Health literacy is considered a “social vaccine” that helps people respond effectively to the pandemic. We aimed to investigate the association between long COVID-19 and PTSD, and to examine the modifying role of health literacy in this association.Methods: A cross-sectional study was conducted at 18 hospitals and health centers in Vietnam from December 2021 to October 2022. We recruited 4,463 individuals who had recovered from COVID-19 infection for at least 4 weeks. Participants provided information about their sociodemographics, clinical parameters, health-related behaviors, health literacy (using the 12-item short-form health literacy scale), long COVID-19 symptoms and PTSD (Impact Event Scale-Revised score of 33 or higher). Logistic regression models were used to examine associations and interactions.Results: Out of the study sample, 55.9% had long COVID-19 symptoms, and 49.6% had PTSD. Individuals with long COVID-19 symptoms had a higher likelihood of PTSD (odds ratio [OR], 1.68; 95% confidence interval [CI] , 1.63–2.12; p 〈 0.001). Higher health literacy was associated with a lower likelihood of PTSD (OR, 0.98; 95% CI, 0.97–0.99; p=0.001). Compared to those with long COVID-19 symptoms and the lowest health literacy score, those with long COVID-19 symptoms and a 1-point health literacy increment had a 3% lower likelihood of PTSD (OR, 0.97; 95% CI, 0.96–0.99; p=0.001).Conclusion: Health literacy was found to be a protective factor against PTSD and modified the negative impact of long COVID-19 symptoms on PTSD.
