RESUMEN
Background: Happiness is among the fundamental concepts in mental health that have an impact on different aspects of university students. In this study, we aimed to estimate the prevalence of happiness among university students in Vietnam and to identify the factors influencing happiness. Design and methods: A cross-sectional survey was conducted on undergraduate students in 8 universities and colleges in Hanoi, Vietnam. Happiness was measured using the Subjective Happiness Scale (SHS), and we used imputed Poisson regression to evaluate associations between happiness and associated factors. Results: Among 9120 participants students (95.1% response rate), the prevalence of "happier group" was 80.9% (95% CI: 80.1-81.7). In the multivariable regression models, factors associated with being "less happy" on SHS were the perceived financial burden, year in university, academic motivation profile, and self-reported depression and anxiety. Conclusions: University healthcare providers should pay attention to these associated factors while designing mental health care programs to promote happiness among university students.
RESUMEN
Diabetes mellitus is characterized by hyperglycemic due to impaired insulin secretion or resistance. In our search for anti-diabetic agents, we found that a 70% EtOH extract of Rubus cochinchinensis(Tratt) enhances glucose uptake in 3T3-L1 adipocytes. R. cochinchinensis is predominantly found in East Asia, particularly in Vietnam, Laos, Cambodia, and southern in China. Despite its widespread distribution, there have been few studies on its bioactivity or chemical constituents. In this study, activity-guided fractionation of 70% EtOH extract from the leaves of R. cochinchinensis resulted in the isolation of one new ursane-type glycoside, 3-O-β-acetyl-28-O-β-D-glucopyranosyl-rotundioic acid (1), along with four known compounds (2–5). The structures of these compounds were elucidated using 1D and 2D NMR and HRESIMS data. Notably, compound 4 significantly increased the uptake level of 2-deoxy-2-[(7-nitro-2,1,3-benzoxadiazol-4-yl)amino]-D-glucose (2-NBDG) in differentiated 3T3-L1 adipocytes. This study suggests the potential of R. cochinchinensis as a promising medicinal plant for treating diabetes via glucose uptake.
RESUMEN
The current limitation of ancient DNA data from Vietnam led to the controversy surrounding the prehistory of people in this region. The combination of high heat and humidity damaged ancient bones that challenged the study of human evolution, especially when using DNA as study materials. So far, only 4 k years of history have been recorded despite the 65 k years of history of anatomically modern human occupations in Vietnam. Here we report, to our knowledge, the oldest mitogenomes of two hunter-gatherers from Vietnam. We extracted DNA from the femurs of two individuals aged 6.2 k cal BP from the Con Co Ngua (CCN) site in Thanh Hoa, Vietnam. This archeological site is the largest cemetery of the hunter-gatherer population in Southeast Asia (SEA) that was discovered, but their genetics have not been explored until the present. We indicated that the CCN haplotype belongs to a rare haplogroup that was not detected in any present-day Vietnamese individuals. Further matrilineal analysis on CCN mitogenomes showed a close relationship with ancient farmers and present-day populations in SEA. The mitogenomes of hunter-gatherers from Vietnam debate the "two layers" model of peopling history in SEA and provide an alternative solution for studying challenging ancient human samples from Vietnam.

Smoking is a global health problem among health science students. The objectives of this study were to estimate the prevalence of smoking and to examine associated factors among health science students from five universities in Vietnam. Among 5946 participants (95.0% response rate), the smoking prevalence was 19.2% (95% CI:17.4-21.0%) among male students and 2.9% (95% CI:2.4-3.5%) among female students. In the multivariable regression models, significant factors for smoking were the perceived financial burden, the respondent's year in university, a non-self-determined motivation profile, self-reported depression and/or anxiety, the level of vigorous physical activity, and alcohol drinking.
RESUMEN
BACKGROUND: Systemic inflammatory response syndrome (SIRS) is common in severe fulminant hepatic failure (FHF) and has a high mortality rate (20-50%) due to irreversible cerebral edema or sepsis. Stem cell-based treatment has emerged as a promising alternative therapeutic strategy to prolong the survival of patients suffering from FHF via the inhibition of SIRS due to their immunomodulatory effects. METHODS: 3D spheroids of adipose-derived mesenchymal stem cells (3D-ADSC) were prepared by the hanging drop method. The efficacy of the 3D-ADSC to rescue FHF was evaluated in a D-galactosamine/lipopolysaccharide (GalN/LPS)-induced mouse model of FHF via intraportal transplantation of the spheroids. RESULTS: Intraportally delivered 3D-ADSC better engrafted and localized into the damaged livers compared to 2D-cultured adipose-derived mesenchymal stem cells (2D-ADSC). Transplantation of 3D-ADSC rescued 50% of mice from FHF-induced lethality, whereas only 20% of mice survived when 2D-ADSC were transplanted. The improved transplantation outcomes correlated with the enhanced immunomodulatory effect of 3D-ADSC in the liver microenvironment. CONCLUSION: The study shows that the transplantation of optimized 3D-ADSC can efficiently ameliorate GalN/LPS-induced FHF due to improved viability, resistance to exogenous ROS, and enhanced immunomodulatory effects of 3D-ADSC.

Bio-guided fractionation of the 70% ethanol extract of Belamcanda chinensis (L.) DC. revealed four new compounds, including 6â³-O-acetylembinin (5), 3â³-O-acetylembinin (6), irigenin 3'-O-ß-glucopyranoside (8), and 2'-acetyl-1,3-O-diferuloylsucrose (9), along with five known compounds (1-4, 7). Their chemical structures were determined using extensive NMR data, mass spectroscopy, and comparison with published literature. Among the isolates, compounds 1 and 4-7 achieved good regulation of the growth and proliferation of vascular smooth muscle cells.
