In this paper, the nonlinear dynamic responses of sandwich-FGM doubly curved shallow (SFDCS) shells subjected to underwater explosions are presented. The SFDCS shells resting on the elastic foundation, and two different types of configuration are considered. Based on the first-order shear deformation theory (FSDT), the governing equations are derived. Galerkin method and fourth-order Runge-Kutta method are applied to analyze the nonlinear dynamic response of the sandwich FGM shell with the simply supported boundary condition at four edges. The numerical results show the effects of geometrical and material parameters, explosive weight, stand-off distance, pre-loaded static biaxial and axial compressions, linear damping coefficient, Winkler/Pasternak foundations on the nonlinear dynamic responses of considered sandwich shells.
α-Thalassemia is a common inherited blood disorder manifested mainly by the deletions of α-globin genes. In geographical areas with high carrier frequencies, screening of α-thalassemia carrier state is therefore of vital importance. This study presents a novel method for identifying female carriers of common α-thalassemia deletions using samples routinely taken for non-invasive prenatal tests for screening of fetal chromosomal aneuploidies. A total of 68,885 Vietnamese pregnant women were recruited and α-thalassemia statuses were determined by gap-PCR, revealing 5344 women (7.76%) carried deletions including αα/−−SEA (4.066%), αα/−α3.7 (2.934%), αα/−α4.2 (0.656%), and rare genotypes (0.102%). A two-stage model was built to predict these α-thalassemia deletions from targeted sequencing of the HBA gene cluster on maternal cfDNA. Our method achieved F1-scores of 97.14–99.55% for detecting the three common genotypes and 94.74% for detecting rare genotypes (−α3.7/−α4.2, αα/−−THAI, −α3.7/−−SEA, −α4.2/−−SEA). Additionally, the positive predictive values were 100.00% for αα/αα, 99.29% for αα/−−SEA, 94.87% for αα/−α3.7, and 96.51% for αα/−α4.2; and the negative predictive values were 97.63%, 99.99%, 99.99%, and 100.00%, respectively. As NIPT is increasingly adopted for pregnant women, utilizing cfDNA from NIPT to detect maternal carriers of common α-thalassemia deletions will be cost-effective and expand the benefits of NIPT.
Left ventricular diverticulum is a rare congenital left ventricular outpouchings. The disease is often diagnosed during childhood because it is frequently associated with midline thoracoabdominal defects and other congenital cardiac anomalies. Most cases are asymptomatic, often discovered incidentally. Some complications have been reported including infarction, arrhythmia, heart failure. The most severe complication is rupture of the diverticulum, which can cause a patient's death. Therefore, this congenital defect should be detected early to assess potential risks for appropriate treatment. In this article, we report a case of a 3-month-old boy with left ventricular diverticulum diagnosed with Doppler ultrasound and cardiac MSCT. Complete resection was undertaken. The patient remained asymptomatic with good heart function 2 months after surgery.
Quercetin has been studied extensively with drug delivery systems due to the drug's needs to improve in solubility, but usually the systems are complicated, evading the practical aspects and potential applications. This problem is expected to be solved using the simplistic micelles, in combination with the materials mPEG and cholesterol to gain advantages from the nano‐size, while increasing its overall stability and drug releasing. In this study PEGylated‐cholesterol micelles were prepared by co‐solvent method in 4 different drug‐polymer ratios, which were then characterized by physical–chemical, in vitro analyses and emphasized on the in vivo cytotoxicity test by H&E staining histological assay on Danio rerio model. The results show promising features of nano‐micelles as a passive drug delivery system in size, CMC value, and prolonged drug releasing profile. Compared to free QCT, the micelles‐loaded system exhibited significantly higher toxicity in vitro, which were also demonstrated in in vivo models, where the drug‐loaded micellar systems posed mild tissue changes, while blank micelles and free quercetin were almost harmless to the animals. The results had concluded that effective delivering of micellar system does not require advanced material‐composition, rather a throughout understanding of the interactions of nano‐properties and the materials with bio‐systems. Quercetin drugs were incorporated in the hydrophobic inner‐section of micellar particles, and the weight ratio between these were examined to optimize the drug‐loading capacity. The micellar nanoparticles were then subject to various analytical experiments, which provide sufficient data about “drug‐delivering” ability of mPEG‐Cholesterol as materials for micelles’ formulations. With the increase in requirements for in vivo tests recently and the limited properties of rodent and mammal models, we have developed a testing protocol using zebrafish (Danio rerio) models to examine in vivo the anti‐cancer drug’ effect on bodily systems.
A feeding factorial experiment was conducted, in which Artemia was enriched with two organic selenium (Se) concentrations (0, 12 mg/L) and three highly unsaturated fatty acids (HUFA) levels (0, 0.3 and 0.6 g/L) to produce six dietary treatments, labelled as H0, H03, H06, H0S; H03S and H06S. The diets were fed to barramundi larvae (11 day after hatching) for 15 days to investigate the combined effects of selenium and HUFA on growth performance, fatty acid composition, skeletal deformities and stress resistance of the larvae. The results showed that enriching Artemia with Se significantly improved the final weight and specific growth rate of the larvae fed non or highest HUFA enrichment levels (P < 0.05). No differences were observed in survival of the larvae fed enriched HUFA diets, but they were significantly higher than those fed unenriched HUFA groups. Dietary Se supplementation significantly increased larval n-3 HUFA and DHA contents. High mortalities were recorded in the larvae fed unenriched HUFA diets, whereas Se supplementation significantly increased the survival of the larvae fed high HUFA level. Fish fed unenriched HUFA Artemia showed significantly higher skeletal deformities than those fed other diets. The results thus indicated the beneficial effects of dietary Se in preventing the reduced growth and stress resistance in the barramundi fed HUFA inclusion diets.
This paper aims to assess the potential of Ocean Land Colour Instrument (OLCI) for the retrieval of chlorophyll-a (chl-a) over southern coastal waters of Vietnam. For that purpose, four chlorophyll-a ocean color (OC) algorithms (OC4ME and three new OC version 7 OC4, OC5, OC6) were applied based on water-leaving reflectance obtained from two atmospheric correction processors (C2RCC and DSF). To overcome high cloud coverage in the area of interest, full spatial data reconstruction was implemented using Data Interpolating Empirical Orthogonal Functions (DINEOF). Numerical error metrics of in situ measurements (n = 49) collected in different ship-based campaigns has been assessed for Sentinel-3A (S-3A) and 3B (S-3B) as well as on the combined products built from these two later satellites. Results showed that products based on C2RRC significantly outperformed DSF. For chl-a algorithms, C2RCC-based OC5 gave the most accurate retrieval while applied to S-3A (R²: 0.58, RMSE: 1.018 mg m⁻³, MAPE: 49.4 %), S-3B (R²: 0.75, RMSE: 0.776 mg m⁻³, MAPE: 37.3 %), and synergy datasets (R²: 0.70, RMSE: 0.844 mg m⁻³, MAPE: 42.5 %). With>50 % of observations missing due to cloud cover, DINEOF provides a promising solution to reconstruct the full spatial information. The successfully demonstrated retrieval of chl-a in our study presents potential for daily monitoring when combining observations from S-3A/B to further improve our understanding of the spatio-temporal dynamics of coastal ecosystems.
The ecological response of nematode communities to dam construction has limited attention. In this study, the response of intertidal nematode communities in the Ba Lai River (Mekong Delta, Vietnam) to the construction of an irrigation dam was investigated. Nematode communities and environmental parameters were investigated during the rainy season of 2015. The obtained results showed that the Ba Lai dam had caused negative impacts on the local environment by disrupting longitudinal connectivity, the accumulation of nutrients (total organic carbon, total nitrogen, total phosphorus), and heavy metals (copper, iron, arsenic, lead) in the upstream and the lateral sides of the dam, consequently leading to changes in the nematode communities. The response of nematode communities to the dam’s presence was clear based on their abundance, diversity, dominant genera, and community composition. Furthermore, changes in the abundance and diversity of nematodes in the Ba Lai River appeared to be controlled primarily by acidity (pH), total suspended solids (TSS), iron (Fe), clay, and salinity most responsible for changes to nematode communities. Because the nematode communities are well adapted to the physicochemical disturbances caused by dam construction, they are a potential tool for ecological monitoring and understanding the influence of dams on aquatic ecosystems.
The Indian movie industry is the largest movie industry based on the number of movies produced per year. It is also the most diverse movie industry.It has been examined in a recent study that only a few of the movies achieved success. Revenue uncertainties have created immense pressure on the motion picture industry. Researchers and film producers continually feel a necessity to have some expert systems that predict the movie’s success probability preceding its production with reasonable accuracy. The diversity of the Indian movie industry makes the problem more difficult. Only a few researchers worked on Indian films, but most of them are targeted prerelease forecasting or have low prediction accuracy. This study focused on Indian movies and concentrated on the upcoming film’s success as soon as a quotient (director, cast) signed an agreement. This proposed forecasting has been considered as the earliest forecasting. Our study retrieved and used the last 30 years of Indian movie information covering all India’s regional movies.We had judicially chosen some of the movie’s intrinsic features and introduced a set of novel derived features to increase the forecasting accuracy. We had proposed a K-fold Hybrid Deep Ensemble learning Model (KHDEM), which includes Deep Learning models (DLM) and ensemble learning models. Finally, We made the prediction using a Logistic Regression (LR) classifier. We had implemented a binary classification model and achieved 96% accuracy, which outperforms all the benchmark models. The introduction of our derived features had improved the accuracy by 17.62%.This study highlights the potential of predictive and prescriptive data analytics in information systems to support industry decisions.
Background and aims: Virtual magnifying chromoendoscopy with flexible spectral imaging color enhancement (FICE), image-enhanced endoscopy techniques, and dye-staining magnifying chromoendoscopy (with Indigo carmine and Crystal violet) have contributed to better visualization of the pit pattern and vascular structure of colorectal polyp. Therefore, magnifying chromoendoscopy is capable of predicting the histopathological results of colorectal polyp without biopsy and remains their diagnostic values over time, especially in scare-setting resources. This study compared the images of magnifying chromoendoscopy between FICE, Indigo carmine, and Crystal violet and then assessed their diagnostic values based on colorectal polyps' histopathology as a gold standard. Methods: A total of 332 polyps of 266 patients were endoscopically evaluated from June 2016 to September 2019. After identified by white light endoscopy, polyps continued to be evaluated by virtual magnifying chromoendoscopy (×50-150 times) with FICE. The capillary-vessel pattern was divided into 5 subtypes according to the number, morphology, and distribution of the fine blood vessels according to Teixeira classification. Next, they were stained with Indigo carmine 0.2% and then Crystal violet 0.05% and were classified according to Kudo's pit pattern classification. Finally, polyps were resected by endoscopy or surgery and biopsy and compared with histopathological results of either neoplastic or nonplastic polyp. Results: The number of neoplastic polyps was 278/332 with 231 adenoma polyps and 47 carcinoma polyps. Magnifying chromoendoscopy has high sensitivity and accuracy when compared with the histopathological results of colorectal polyps. The sensitivity, specificity, and accuracy of magnifying chromoendoscopy with Crystal violet are 97.2%, 72.2%, and 93.0%; with Indigo carmine are 96.0%, 72.2%, and 92.1%; and with FICE are 92.1%, 68.5%, and 88.3%. Conclusions: Among the three methods, Crystal violet has the highest sensitivity and accuracy in predicting histopathological results of colorectal polyps. FICE has shown its diagnostic value with reliable sensitivity and accuracy and should still be a reasonable endoscopic choice for physicians in scare-setting resources regardless its moderate specificity. Physicians should base on their facility and capability to determine an appropriate endoscopy technique.
Some substituted isatins 3a–3c were prepared by Sandmeyer’s synthesis from different substituted anilines 1a–1c and transformed into corresponding N-alkyl isatins 4a–4j. These substituted N-alkyl isatins were condensed with N-(2,3,4,6-tetra-O-acetyl-β-d-glucopyranosyl)thiosemicarbazide to give new substituted isatin N-(2,3,4,6-tetra-O-acetyl-β-d-glucopyranosyl)thiosemicarbazones 6a–6j with different substituents at 1-, 5- and 7- as well as 5,7-positions of isatin ring. The antibacterial as well as antifungal activity of these thiosemicarbazones was estimated using minimum inhibitory concentration protocol. Amongst these compounds, 6h, 6c, and 6h had excellent inhibitory activity against Staphylococcus aureus, and 6h was the best active one. Induced fit docking and MM-GBSA study was showed that compound 6h had binding efficiency and steric interactions in the active site of S. aureus DNA Gyrase (2XCS) with three hydrogen-bonding interactions to residues Arg1122 on chain B, Asp1083 and Arg1122 on chain D, which suggested that the tested compound inhibited this enzyme in S. aureus.

Accurate species identification is of primary importance in ecology and evolutionary biology. For a long time, the unionid mussels Beringiana and Sinanodonta have puzzled researchers trying to unravel their diversity because of their poorly discernible morphologies. A recent study conducted species delineation of unionid mussels based on mitochondrial DNA variation, opening up a new avenue to grasp species diversity of the mussels. However, mtDNA-based classification may not align with species boundaries because mtDNA is prone to introgression and incomplete lineage sorting that cause discordance between species affiliation and gene phylogeny. In this study, we evaluated the validity of the mtDNA-based classification of unionid mussels Beringiana and Sinanodonta in Japan using mitochondrial sequence data, double digest restriction site-associated DNA library (ddRAD) sequencing, and morphological data. We found significant inconsistencies in the mitochondrial and nuclear DNA phylogenies, casting doubt on the reliability of the mtDNA-based classification in this group. In addition, nuclear DNA phylogeny revealed that there are at least two unionid lineages hidden in the mtDNA phylogeny. Although molecular dating technique indicates that Beringiana and Sinanodonta diverged more than 35 million years ago, their shell morphologies are often indistinguishable. Specifically, morphological analyses exhibited the parallel appearance of nearly identical ball-like shell forms in the two genera in Lake Biwa, which further complicates species identification and the morphological evolution of unionid mussels. Our study adds to a growing body of literature that accurate species identification of unionid mussels is difficult when using morphological characters alone. Although mtDNA-based classification is a simple and convenient way to classify unionid mussels, considerable caution is warranted for its application in ecological and evolutionary studies.
Distinguishing the significance of business environments for technical small and medium-sized enterprises (SMEs), this study examines the connection between business environments, GDP growth, and SMEs’ financing choices in Vietnam. The study considered the agency theory as a theoretical base to explain how information asymmetry between SMEs and lenders influences SMEs’ financing choices and encompasses the effects on business environment and GDP growth of Vietnam. For this binary logistic regression, text is applied. Global Entrepreneurship Monitor and World Bank data were analyzed. The findings of the study are robust and showed that SME financing (e.g., formal and informal) under the financial infrastructure and tax regulation may enhance formal credit choice and reduce informal credit choice. This enhances the depth in the business environment of technical SMEs and found significant effects on GDP growth. For the first time, this research examines the impact of information asymmetry and agency theory on restaurant financing choices. The research has significance for industry practitioners and governments interested in SMEs’ financial viability. On the recent topicality, study also presents policy implications for key stakeholders.
As the main component of bones and teeth, hydroxyapatite (HAp) is considered a vital biomaterial in many fields. Meanwhile, fishbone by-products were used as abundant and cheap sources of natural HAp. The preparation of nano-HAp from fish bones not only contributes to increasing the value of by-products but also minimizes negative impacts on the environment. In this study, nano-HAp was successfully obtained from Lates calcarifer fish bone by the thermal calcination method. Analysis of SEM, TEM showed that the HAp nanopowders possessed an average size of 39.42 nm. The Ca/P molar ratio of 1.845 indicated that the nano-HAp powders were B-type biological hydroxyapatites, which has been confirmed by FTIR spectrum. In addition, the content of heavy metals including As, Pb, Hg, Cd and the microbial contamination are within safety limits of regulatory requirements of Vietnam regulation and US Pharmacopeia for food and dietary supplement standard. The other elements such as Fe, K, Mg, Na, Se, Zn are also present in nano-HAp. The investigation of acute toxicity shows that nano-HAp did not exhibit toxicity in Swiss mice at the highest dose of 6000 mg/kg body weight. The results of subchronic oral toxicity testing indicated that nano-HAP did not affect the behavior, body weight and hematological parameters of rabbits at doses of 50 and 100 mg/kg body weight for 28 days. The liver function indices (AST, ALT, GGT) and kidney function index (creatinine) are within normal limits. These properties suggest that nano-HAp from Lates calcarifer fish bones can be used as material in food and medicine fields.
Oculocutaneous albinism (OCA) is an autosomal recessive disease with hypopigmentation in skin, hair, and eyes, causing by the complete absence or reduction of melanin in melanocytes. Many types of OCA were observed based on the mutation in different causing genes relating to albinism. OCA can occur in non‐syndromic and syndromic forms, where syndromic OCA coexists with additional systemic consequences beyond hypopigmentation and visual‐associated symptoms. We performed whole exome sequencing in seven affected individuals (P1‐P7) for mutation identification, and then, Sanger sequencing was used for verifications. Among them, five patients (P1‐P5) have mutations on TYR gene including c.346C > T, c.929insC, c.115 T > C, and c.559_560ins25. The mutation on OCA2 and HPS1 genes was found in patient 6 (P6, OCA2 c.2323G > A) and patient 7 (P7, HPS1 c.972delC), respectively. Confirmation in parents (except the family of the elderly patient, P5) showed that the mother and the father in each family carried one of the variants that were detected in patients. Additionally, the effective genetic counseling was applied in the third pregnancy of a family with two OCA children (P1 and P2). To our best knowledge, this is the first case with a novel homozygous missense mutation (c.115 T > C, p.W39R) in the TYR gene. This study provides a broader spectrum of mutations linked to the oculocutaneous albinism, an additional scientific basis for diagnosis, and appropriate genetic counseling for risk couples.

Five known secondary metabolites, namely 2-(2-heptenyl)-3-methyl-4-quinolinone (1), 3-methyl-2-(2-nonenyl)-4-quinolinone (2), 2-phenylacetic acid (3), 4-hydroxybenzoic acid (4), and (-)-jasmonic acid (5) were isolated and identified from the crude extract of an endophytic bacterium Bacillus sp. RAR_M1_45 from the mangrove plant Rhizophora apiculata Cytotoxic assays showed that compounds 1 and 2 exhibited cytotoxicity against the tested cancer cell lines A549 (human lung carcinoma), MCF7 (human breast carcinoma) and KB (human mouth epidermal carcinoma) with IC50 values from 65.09 ± 2.06 to 97.88 ±4.16μg/mL, whereas antimicrobial assays showed that compounds 1–3 exhibited selective antimicrobial activity against plant pathogens with MICs of 16–64 μg/mL. Additionally, compounds 1–5 exhibited α-amylase and α-glucosidase inhibitory effects with IC50 values from 63.87 ± 4.23 to 649.9 ±17.5μg/mL and from 163.3 ± 10.66 to 960.4 ±8.62μg/mL, respectively. Experimental bioassays also revealed that the α-amylase and α-glucosidase inhibitory activities of the isolated compounds were consistent with computational docking results. Regarding ligand-7TAA systems, the potential stability of the complexes by molecular docking simulation was high consistence on the order of α-amylase inhibitory assays: 5 (DS -11.9 kcal.mol ⁻¹) > 4 (DS -11.3 kcal.mol ⁻¹) > 3 (DS -10.7 kcal.mol ⁻¹) > 2 (DS -9.9 kcal.mol ⁻¹) > 1 (DS -9.0 kcal.mol ⁻¹). Regarding ligand-3W37 systems, the potential stability of the complexes by molecular docking simulation was high consistence on the order of α-glucosidase inhibitory assays: 5 (DS -12.8 kcal.mol ⁻¹) > 4 (DS -12.1 kcal.mol ⁻¹) > 3 (DS -11.7 kcal.mol ⁻¹) > 2 (DS -10.0 kcal.mol ⁻¹) > 1 (DS -9.8 kcal.mol ⁻¹).
Several species of the genus Lysimachia L. (Primulaceae) are well known in folk medicine, but very few studies have been conducted on them. The aim of our study was to investigate the microscopical characteristics and chemical composition of Lysimachia insignis Hemsl., L. decurrens G. Forst., and L. congestiflora Hemsl. as well as to evaluate some biological activities of their methanol extracts. The transverse sections of stem and powder characteristics of the three Lysimachia species shared some similarities. Also, some differences were indicated. The chemical investigation of three aforesaid species including the preliminary phytochemical screening, the quantification of the total polyphenol content and total flavonoid content, as well as the determination of metabolites. The phytochemical screening showed the presence of flavonoids, saponins, tannins and sterols in all the three species. On the other hand, coumarins were detected in L. insignis while anthranoids were present in L. decurrens and L. congestiflora. The total polyphenol content and the total flavonoid content of the aforesaid species were determined by the spectrometric method. The metabolite profiling approach of three species was performed by LC-Q-ToF-HRMS and HPTLC. The methanol extract of L. insignis showed a weak inhibitory effect on NO production (I% = 57.4 at the concentration of 100 µg/ml) while the extract of L. decurrens exhibited moderate anti-oxidant activity in vitro (SC% = 62.5 at the concentration of 100 µg/mL).
In this work, we systematically examine the electronic features and contact types of van der Waals heterostructures (vdWHs) combining single-layer boron phosphide (BP) and Janus Ga2SSe using first-principles calculations. Owing to the out-of-plane symmetry being broken, the BP/Ga2SSe vdWHs are divided into two different stacking patterns, which are BP/SGa2Se and BP/SeGa2S. Our results demonstrate that these stacking patterns are structurally and mechanically stable. The combination of single-layer BP and Janus Ga2SSe gives rise to an enhancement in the Young's modulus compared to the constituent monolayers. Furthermore, at the ground state, the BP/Ga2SSe vdWHs possess a type-I (straddling) band alignment, which is desired for next-generation optoelectronic applications. The interlayer separation and electric field are effectively used to tune the electronic features of the BP/Ga2SSe vdWH from the type-I to type-II band alignment, and from semiconductor to metal. Our findings show that the BP/Ga2SSe vdWH would be appropriate for next-generation multifunctional optoelectronic and photovoltaic devices.
Fertilizer originated nitrate excess in vegetables has attracted numerous studies for its effects on food quality. However, the relationship between plant nitrate accumulation and fertilizer-derived nitrogen (FTN) in the soil in continuous research is rarely reported. This study examines the impact of conventional ammonium fertilizer application (50.4 kg/ha) on the constant trend of soil nitrogen and plant nitrate uptake of 8 common leafy vegetables grown in Red Delta River, Vietnam. The vegetables reveal both FTN and plant nitrate took about 17 days to release from topsoil and plant. The trend of FTN is well fitted by a regression model (Decay model, R2=0.945, p<0.001), which shows the nitrogen loss rate of FTN range from 0.120-0.139 g N/day. Meanwhile, the trend of plant nitrate uptake fitted the quadratic equation (R2=0.889, p<0.01). Although the correlation between FTN and plant nitrate is weak, this study finds that autumn crops have a tighter relationship than summer crops (R=0.71 and R=0.46, respectively). It can be concluded that regression models could be suitable methods to observe the behavior of fertilizer nitrogen in soil and vegetable uptake.
Honey bees are important pollinators for the conservation of the ecosystem and agricultural products and provide a variety of products important for human use, such as honey, pollen, and royal jelly. Sacbrood disease (SD) is a devastating viral disease in Apis cerana; an effective preventive measure for SD is urgently needed. In this study, the relationship between the gut microbiome of honey bees and SD was investigated by pyrosequencing. Results revealed that sacbrood virus (SBV)-resistant A. cerana strains harbour a unique acetic acid bacterium, Bombella intestini, and the lactic acid bacteria (LAB) Lactobacillus (unclassified)_uc, Bifidobacterium longum, B. catenulatum, Lactococcus lactis, and Leuconostoc mesenteroides in larvae and Hafnia alvei, B. indicum, and the LAB L. mellifer and Lactobacillus HM215046_s in adult bees. Changes in the gut microbiome due to SBV infection resulted in loss of bacteria that could affect host nutrients and inhibit honey bee pathogens, such as Gilliamella JFON_s, Gilliamella_uc, Pseudomonas putida, and L. kunkeei in A. cerana larvae and Frischella_uc, Pantoea agglomerans, Snodgrassella_uc, and B. asteroides in adult bees. These findings provide important information for the selection of probiotics for A. cerana larvae and adults to prevent pathogenic infections and keep honey bees healthy.
