In this work we discuss a new $\mathrm{SU}(3{)}_{C}\ensuremath{\bigotimes}\mathrm{SU}(3{)}_{L}\ensuremath{\bigotimes}\mathrm{U}(1{)}_{X}\ensuremath{\bigotimes}\mathrm{U}(1{)}_{N}$ (3-3-1-1) gauge model that overhauls the theoretical and phenomenological aspects of known 3-3-1 models. Additionally, derive outcome 3-3-1-1 from precise electroweak bounds to dark matter observables. We firstly advocate if $B\ensuremath{-}L$ number is conserved as electric charge, extension standard symmetry one...
Monofloral honey samples (Coffea robusta) from Vietnam were determined for their chemical compositions. This is the first report on composition and antioxidant activity of coffee Vietnam. These characterized by high contents total reducing sugars, phenolic contents, flavonoid contents. The seven acids (PAs) quantified performance liquid chromatography (HPLC) analyzed with assistance principle component analysis (PCA) to differentiate into groups. hydroxymethylfurfural (HMF) (0.048-2.933...
We consider the $\mathrm{SU}(3{)}_{C}\ensuremath{\bigotimes}\mathrm{SU}(3{)}_{L}\ensuremath{\bigotimes}\mathrm{U}(1{)}_{X}\ensuremath{\bigotimes}\mathrm{U}(1{)}_{N}$ (3-3-1-1) model at grand unified theory scale with implication for inflation and leptogenesis. The mass spectra of neutral Higgs bosons gauge are reconsidered when 3-3-1-1 breaking is much larger than that ordinary $\mathrm{SU}(3{)}_{C}\ensuremath{\bigotimes}\mathrm{SU}(3{)}_{L}\ensuremath{\bigotimes}\mathrm{U}(1{)}_{X}$ (3-3-1)...
Colorectal cancer is among the most common malignancies and can develop from high-risk colon polyps. Colonoscopy an effective screening tool to detect remove polyps, especially in case of precancerous lesions. However, missing rate clinical practice relatively high due many factors. The procedure could benefit greatly using AI models for automatic polyp segmentation, which provide valuable insights improving detection. precise segmentation still challenging variations polyps size, shape,...
Abstract In 2022, a large dengue outbreak was reported in Vietnam, where endemic. A total of 1889 acute‐phase serum samples were collected from patients with suspected at Vung Tau General Hospital, the core hospital Province, southern Vietnam. Among analyzed for laboratory confirmation virus (DENV) infection, 339 positive cases identified, which 130 primary infections and 209 secondary infections. DENV‐2 dominant serotype both infection groups. Phylogenetic analysis based on sequences...
A total of 239 isolates blast (Pyricularia oryzae Cavara) collected from northern and central Vietnam showed a wide variation in pathogenicity based on the reaction patterns to 25 differential varieties (DVs) harboring 23 resistance genes susceptible cultivar Lijiangxintuanheigu (LTH). The frequencies virulent toward DVs for Pish, Pik-m, Pi1, Pik-h, Pik, Pik-p, Pi7(t), Pi9(t), Piz-5, Pita-2, Pita were low, but they high Pib, Pit, Pia, Pii, Pi3, Pi5(t), Pik-s, Piz, Piz-t, Pi12(t), Pi19(t),...
A series of sixteen A-ring modified (2,3-indolo-, 2-benzylidene) oleanonic acid derivatives, holding some cyclic amines, linear polyamines and benzylaminocarboxamides at C28, has been synthesized screened for antiviral activity against influenza A/PuertoRico/8/34 (H1N1) Dengue virus serotypes DENV-1, -2, -3, -4. It was found that 28-homopiperazine 2 3-N-phthalyl 22 amides demonstrated high potency with selectivity index SI 27 (IC50 21 μM) 42 12 μM). Oleanonic aminoethylpiperazine amide 6...
Dengue virus (DENV) comprises four serotypes in the family Flaviviridae and is a causative agent of dengue-related diseases, including dengue fever. fever generally self-limited febrile illness. However, secondary infection patients with suboptimal antibody (Ab) response provokes life-threatening severe hemorrhagic or shock syndrome. To develop potent candidate subunit vaccine against DENV infection, we developed EDII-cEDIII antigen, which contains partial envelope domain II (EDII) fusion...
For the successful implementation of integrated STEM education, teachers' competence could be a key element. The purpose this research is to identify necessary behaviors for teaching subjects more efficiently and their desire professional development courses. qualitative analysis was utilized examine perceptions effective teacher developments (TPD). Semi-structure interview method with 15 teachers survey 187 were address our questions in Vietnam. We found that education consists four...
This cross-sectional study is to examine the prevalence of depression and associated factors among 110 ethnic minority elderly in Kon Tum city, Vietnam. Depression was assessed using 30-items Geriatric Scale. Multivariate linear regression analysis employed identify with depression. The participants 25.5%. All were classified as mild level. significantly age, gender, educational level, chronic diseases, stressful life events past 12 months, family history These risk can help formulate...
Acute encephalitis syndrome (AES) is associated with high morbidity and mortality, affects both children adults. The main etiologic agent Japanese virus (JEV); however, there are also reports of Dengue (DENV) encephalitis. objectives this study were to determine the proportion patients due JEV during 2014 outbreak in Son La Province Vietnam explore association DENV non-JEV viral cases. Of 90 patients, 6 (6.7%) positive for anti-JEV immunoglobulin M (IgM), 5 (5.6%) anti-DENV IgM, 30 (33.3%)...
Aims: This study aims to investigate the relationship between personality traits and anxiety disorder, in which mediating role of social support self-esteem is also explored. Background: In Vietnam, disorder a major challenge affecting adolescents’ academic functioning. Objectives: Examine whether are related their disorders mediate disorders. Methods: A sample population 582 early adolescents at four secondary schools Vietnam voluntarily participated through completion big-five dimension...
The Zika virus (ZIKV) is believed to cause birth defects, and no anti-ZIKV drugs have been approved by medical organizations date. Starting from antimicrobial lead compounds with a pyrazolo[3,4-d]pyridazine-7-one scaffold, we synthesized 16 derivatives screened their ability interfere ZIKV infection utilizing cell-based phenotypic assay. Of these, five showed significant inhibition of selective index value greater than 4.6. In particular, compound 9b the best activity selectivity 22.4...
This research explored coping behaviors and psychological difficulties in Vietnamese middle school students determined relationship between these variables.A sample population of 582 early adolescents from four secondary schools Vietnam who aged 11 to 14 voluntarily participated the study.Measurements included a brief cope self-report questionnaire employing Likert scale including difficulties.The results revealed that suffered considerable levels specific accounted for 27.8 percent variance...
Abstract Dengue fever pandemic caused by dengue virus has been claimed for many lives, however, no specific treatment is available. Prevention based on vector control posed to be the most effective measure so far. The application of chitosan stabilized silver nanoparticle (AgNPs) larvae and adult mosquitoes recently discovered, but their ability inhibit scarcely discussed. In this study, AgNPs have prepared tested against type 1. results showed that can 96.66% 98.33% 1 at 12.50 ppm 25.00...
Abstract Antidenge activity of the n ‐hexane, ethyl acetate and ‐butanol extracts from leaves Carica papaya against four dengue virus serotypes (DENV1‐4) were evaluated. As a result, ‐hexane extract showed best antiviral on all denge with PNRT 50 15.625 to 31.25 μg/ml. From extract, nine compounds including cycloartenol ( 1 ), cycloart‐23,25‐dien‐3 β ‐ol 2 cycloart‐25‐ene‐3 ,24 ‐diol 3 α 4 25‐hydroxycycloart‐23‐ene‐3‐one 5 ‐sitosterol 6 stigmasterol 7 nonacosan‐1‐ol 8 all‐ trans...
