    Abstract: The prevalence of mental health disorders among people who use drugs is high and well documented. This hard‐to‐reach population faces a very low awareness and access to mental health care, especially in developing countries. The objectives of this study were to design and assess a quick screening tool (QST) that community‐based organisations (CBO) could routinely apply to a Vietnamese population of people who inject drugs (PWID), in order to refer them appropriately to mental health specialists. Methods We devised a tool that included nine questions covering anxiety, depression, suicide risk and psychotic symptomatology. Its use required no specific background and 2 h training. Specificity and sensitivity of the QST were assessed in a population of 418 PWID recruited via respondent driven sampling, using the Mini International Neuropsychiatric Interview questionnaire plus clinical evaluation as a reference standard. Acceptability was assessed using a self‐administered anonymous questionnaire submitted to all CBO members who used the QST. Results CBO members considered the QST easy to use, relevant and helpful to deal with mental health issues. Area under the curve for detection of any symptom using the QST was 0.770. The maximum sensitivity and specificity were reached with a cut‐off of 2 [sensitivity was 71.1% (95% confidence interval 62.4, 78.8), specificity was 75.9% (70.5, 80.7)]. Discussion and Conclusions The QST appeared to be both efficient and well accepted. Given the burden of mental health problems among hard‐to‐reach PWID in developing countries, community‐based screenings such as this one could be a particularly appropriate response.

    Abstract: This article aims to investigate the seasonality of gold prices at the Shanghai Gold Exchange over the 2002–2016 period. Our contributions rely in the distinction between risk‐averse and risk‐seeking investors regarding their investment strategies. The results show the existence of positive Monday and January effects. However, the Monday effect is more suitable to risk‐seeking investors while the January effect is more suitable to risk‐averse investors in bearish periods only. A robustness check shows that the Monday effect does not hold on gold futures prices. These results indicate the importance to consider the risk‐aversion level of investors in seasonal investment strategies.

    Abstract: The objective of this paper is to investigate the relationship between environmental performance and financial performance on a sample of 361 U.S. firms over the 2007–2016 period. We contribute to the literature by considering firms active in sustainable innovations by obtaining green patents. We also contribute to the literature by using disaggregated measures of environmental performance collected from the Bloomberg ESG database, including environmental disclosure score, greenhouse gas emissions, waste emissions and water use. Panel data regressions' results show that environmental transparency positively influences current accounting and stock market performance, but negatively influences the return on capital employed. Furthermore, lower pollution emissions tend to improve the current return on assets, while being harmful for the efficiency of long‐term capital employment at the same time. The empirical results also indicate that the Global Financial Crisis (2007–2010) increased the environmental transparency of firms with green patents but negatively impacted their price to earnings ratio. At the same time, lower waste disposal diminishes stock valuation while the opposite is true with water use. Taken together, our results suggest that environmental transparency and greenhouse gas emissions generally appear to be the most important environmental variables influencing financial performance, with increasing importance attributed to them by the market after the global crisis period.

    Abstract: The surface‐enhanced Raman scattering (SERS) is a powerful spectroscopic technique for ultrasensitive and selective biochemical detection due to its capability of providing the “fingerprint” of information of molecular structures at low concentrations. Herein, mesoporous silicon (MPSi)‐based nanocomposites containing silver nanoparticles (AgNPs) provide novel efficient substrates for the detection of molecules. The quasi‐3D‐structured SERS substrate is formed by introducing Ag into the MPSi hollow column‐shaped nanostructure. This SERS substrate uniquely combines the ability of metal surfaces to amplify Raman scattering signals with an enlarged surface area and the increasing light–matter interaction duration that generates large SERS signals for the detection of chemicals. The proposed SERS substrate is verified by detecting orange methylene in solutions at ultralow concentration in the range of 10 −11 –10 −6   m with a linear‐dependent coefficient of R 2  = 0.99922 and the SERS enhancement factor is achieved up to 10 10 . Moreover, the proposed platform can detect diphenylamine with ultralow concentration of 10 −10  m and reliable reproducibility with an average relative stand deviation of 6.3%. The ability for MPSi substrate to detect target molecules at low concentrations helps pave a way to develop the detection tool for integrated, on‐chip devices.

    In: Food Science & Nutrition, Wiley
    Abstract: Anthocyanin, a main‐colored bioactive compound found in Hibiscus sabdariffa L., is well‐known for a varied range of applications as food additives in foodstuff, and natural colorants in food, pharmaceutical, and printing industries. The study aimed to find out the suitable conditions for the spray‐drying process to obtain anthocyanin powder from the extract as well as characterized the powder. In addition, the obtained powder was applied to marshmallows and determined the acceptability of appearance, quality, and scavenging capacity of the candy. The carrier of maltodextrin and gum arabic was selected for spray‐drying, which had optimal conditions at 144°C and 7 mL/min, resulting in 100.22 mg/g anthocyanin content with an encapsulation efficiency of 93.87%. The obtained anthocyanin has appropriate moisture of 5.14%, quite appropriate bulk density, and tapped density, it also was high solubility, and poor flowability but easy compression. The shape of the particle by SEM analysis was low particle size (2–10 μm), wrinkled, unequal spherical size, rough surfaces with indentations, and slight cracks. The X‐ray diffraction (XRD) spectrum of the sample had very low crystallinity and diffuse wide peaks revealing that anthocyanin still exists inside maltodextrin particles. The FT‐IR spectrum had oscillations of characteristic groups of anthocyanin structure. Marshmallow samples added 5% anthocyanin powder gained high acceptability of appearance and maintained the scavenging capacity (DPPH) with an IC50 value of 7368.31 ppm after a month of storage.

    Abstract: Previous studies examined the relationship between intellectual capital and a firm's performance. However, the moderating role of corporate governance—a fundamental factor leading to improved firm performance and increased intellectual capital accumulation—has largely been ignored, particularly in an emerging market such as Vietnam. As such, this study examines the moderating role of corporate governance on the intellectual capital–performance nexus in Vietnam. This study uses a sample of 45 listed firms in Vietnam from 2011 to 2018. The generalized method of moments (GMM) technique is utilized in this paper to enhance the robustness of the findings. The modified value‐added intellectual coefficient (MVAIC) model is used to measure intellectual capital. A firm's performance is proxied by both returns on assets and equity. Our results indicate that intellectual capital components such as capital employed efficiency, human capital efficiency and structural capital efficiency provide a significant and positive effect on a firm's performance. In addition, the results reveal that the inclusion of corporate governance as a moderating factor affects the relationship between intellectual capital and a firm's performance in Vietnam. Findings from this paper provide a valuable framework and implications for executives and policymakers in creating and managing intellectual capital within the Vietnamese context. Besides, improving corporate governance is critical to improving intellectual capital accumulation. To the authors' best knowledge, our literature review indicates that this is the first empirical study that examines the relationship between intellectual capital and a firm's performance using corporate governance as a moderating factor in Vietnam.

    Abstract: The overarching demand of modern electronics and electrification of transportation has tremendously increased usage of rechargeable lithium‐ion batteries (LIBs). As a result, massive amounts of solid waste are generated from the end‐of‐life LIBs and expected to increase by two‐ to threefolds in the near future. Without proper recycling strategies and infrastructure, the immediate threat of environmental pollution and wastage of resources is clear. One way to circumvent these challenges is to recycle the spent LIBs and recover the components and materials, especially heavy metals for future repurposing applications. This review highlights the recent discoveries on the use of deep eutectic solvents (DESs) as an economical and environmentally friendly medium for metal recovery from spent LIBs. Herein, how the different hydrogen donors and acceptors affect the overall performance of DES in terms of leaching efficiency, time, temperature, and metal recovery rates are outlined. Very importantly, the mechanism of metal leaching from the metal oxides using DES is discussed. Finally, some potential strategies and opportunities for further development of novel DES for metal‐recovery from not only spent LIBs but also other industries such as, mining, oil, and agriculture are outlined.

    Abstract: Genetic characteristics were investigated based on short tandem repeat (STR) data to assess the relationship between two Vietnamese Bouyei populations in Vietnam. Methods We collected hair and buccal swab samples from two separate Bouyei populations in the mountainous region of Northern Vietnam, which are the Bo Y in Ha Giang Province and the Tu Di in Lao Cai Province. The study included data of 23 autosomal and 27 Y‐chromosome STRs loci of 96 unrelated participants from a total Vietnamese Bouyei population of under 3300 individuals. Results The results showed that these STR markers are valuable for differentiation of individuals and human genetic studies in Vietnamese Bouyei populations. Genetic analysis indicated that Tu Di and Bo Y people were from the same Bouyei population in China. Conclusions The results supported the official historical records of the region and the classification of the Vietnamese government. Furthermore, the genetic data provided in this study will be helpful in investigating the genetic genealogy evolution and settlement or migration patterns of the Bouyei populations in Vietnam.

    Abstract: The Vietnamese Ban pig is a precious genetic resource that needs to be preserved. In vitro embryo production from in vitro matured (IVM) oocytes is an important tool for the utilization of cryopreserved porcine sperm. The aim of this study was to compare two media for the IVM of Ban pig oocytes. Immature oocytes were subjected to IVM either in a non‐defined (TCM‐199 + pig follicular fluid) or in a defined base medium (POM + epidermal growth factor). At the end of IVM, the oocytes were in vitro fertilized (IVF) with frozen Ban sperm. Ten hours after IVF, the oocytes were either subjected to orcein staining to check fertilization and maturation status or cultured in vitro for 7 days. There was no difference between the two IVM media in terms of percentages of oocyte maturation and blastocyst production. However, the percentage of male pronuclear formation after IVF and the total cell numbers in blastocysts were higher with the defined system. Zygotes obtained by the two IVM systems survived vitrification at similar rates. In conclusion, the two IVM systems were both effective for the production of Ban pig embryos; however, better embryo quality was achieved with the defined one.

    Abstract: Several inherited metabolic diseases are underreported in Vietnam, namely glucose‐6‐phosphate dehydrogenase deficiency (G6PDd), phenylketonuria (PKU) and galactosemia (GAL). Whilst massively parallel sequencing (MPS) allows researchers to screen several loci simultaneously for pathogenic variants, no screening programme uses MPS to uncover the variant spectra of these diseases in the Vietnamese population. Methods Pregnant women (mean age of 32) from across Vietnam attending routine prenatal health checks agreed to participate and had their blood drawn. MPS was used to detect variants in their G6PD, PAH and GALT genes. Results Of 3259 women screened across Vietnam, 450 (13.8%) carried disease‐associated variants for G6PD , PAH and GALT . The prevalence of carriers was 8.9% (291 of 3259) in G6PD and 4.6% (152 of 3259) in PKU , whilst GAL was low at 0.2% (7 of 3259). Two GALT variants, c.593 T  〉  C and c.1034C  〉  A, have rarely been reported. Conclusion This study highlights the need for routine carrier screening, where women give blood whilst receiving routine prenatal care, in Vietnam. The use of MPS is suitable for screening multiple variants, allowing for identifying rare pathogenic variants. The data from our study will inform policymakers in constructing cost‐effective genetic metabolic carrier screening programmes.
