In Vitro and in Silico Study of New Biscoumarin Glycosides from Paramignya trimera against Angiotensin-Converting Enzyme 2 (ACE-2) for Preventing SARS-CoV-2 Infection.

In Vietnam, the stems and roots of the Rutaceous plant Paramignya trimera (Oliv.) Burkill (known locally as "Xáo tam phân") are widely used to treat liver diseases such as viral hepatitis and acute and chronic cirrhosis. In an effort to search for Vietnamese natural compounds capable of inhibiting coronavirus based on molecular docking screening, two new dimeric coumarin glycosides, namely cis-paratrimerin B (1) and cis-paratrimerin A (2), and two previously identified coumarins, the trans-isomers paratrimerin B (3) and paratrimerin A (4), were isolated from the roots of P.

Enhanced acetone gas-sensing characteristics of Pd-NiO nanorods/SnO nanowires sensors.

Acetone is a well-known volatile organic compound that is widely used in different industrial and domestic areas, but it can cause dangerous effects on human health. Thus, the fabrication of highly sensitive and selective sensors for recognition of acetone is incredibly important. Here, we prepared the SnO/Pd-NiO (SPN) nanowires-based gas sensor for the detection of acetone, in which, the amount of Pd nanoparticles were varied to enhance the performance of the devices.

Drug utilization and medical expenses in psoriasis treatment at a dermatology hospital in Vietnam, 2019-2021.

Introduction: Psoriasis is a persistent, chronic, inflammatory cutaneous disorder that recurs frequently and has negative impacts on the living quality of sufferers.

Methods: Data from the Inpatient and Outpatient Department medical records at Can Tho dermatology hospital were used to generate a descriptive statistics report on medicines and medical costs for psoriasis therapy in 2019-2021.

Results: The average number of prescription medications varied annually, averaging roughly 0.

Green, facile and fast synthesis of silver nanoparticles by using solution plasma techniques and their antibacterial and anticancer activities.

We herein present a simple, fast, efficient and environmentally friendly method for preparing silver nanoparticles (AgNPs) using the solution plasma method in the presence of extracts from (). The effects of extract concentrations and the applied voltage on the formation of AgNPs were investigated. Surface plasmon resonance spectra show a strong peak at 413 nm for the prepared samples.

Boron Silicon BSi and BSi Clusters: The Smallest Aromatic Ribbons.

The small binary boron silicon clusters BSi with going from -2 to +2 and BSi with varying from -3 to +1 were reinvestigated using quantum chemical methods. The thermodynamic stability of these smallest ribbon structures is governed by both Hückel and ribbon models for aromaticity. The more negative the cluster charge, the more ribbon character is shown.

Optical properties and stability of small hollow gold nanoparticles.

In the current work, small hollow Au nanoparticles ( ≈ 16 nm) with excellent thermal stability and high photo-thermal conversion efficiency, which have great potential for use in photo-thermal cancer therapy, were prepared through galvanic replacement reaction between Ag nano-templates and gold salt. The position of surface plasmon resonance (SPR) bands for these nanoparticles could be tuned by varying the amount of gold salt. The hydrophobic hollow nanostructures were made water-dispersible by being encapsulated with poly(maleic anhydride--1-octadecene) - PMAO.

The binary boron lithium clusters BLi with = 1-14: in search for hydrogen storage materials.

Molecular structures and properties of the binary clusters containing twelve boron atoms mixed with lithium atoms, BLi with = 1-14, were investigated using density functional theory with the TPSSh functional and the 6-311+G(d) basis set. Energetic parameters including relative energies, average binding energies and second-order energies of the entire series were predicted using the coupled-cluster theory (U)CCSD(T) in conjunction with the cc-pVTZ basis set. Several lowest-lying isomers were determined for each size BLi whose energies differ from each other by <3 kcal mol, except for = 1, 2 and 4 (≤5 kcal mol), and particularly = 8 (∼13 kcal mol).

Extra-Curricular Activities Improved Reproductive Health Knowledge of Ethnic Minority High School Students in Vietnam.

To assess the effectiveness of extra-curricular activities in improving reproductive health knowledge of ethnic minority students in mountainous areas in Vietnam. The study was conducted on 400 ethnic minority students at Dien Bien Dong Ethnic Minority High School in Vietnam. The selected healthy students with a similar mix of study results and grades were divided into two groups: a control group had no the extra-curricular activities on reproductive health, and an experimental group participated extra-curricular activities on reproductive health.
