In vitro, in vivo , and computational evaluation of xanthine oxidase inhibitory and antihyperuricemic activities of Piper betle L. ethyl acetate fraction

Abstract Objectives Gout is a metabolic disorder characterized by hyperuricemia and urate crystal deposition. This study evaluated the xanthine oxidase inhibitory, antihyperuricemic, anti-inflammatory, analgesic, and in silico target-binding properties of an EtOAc fraction of Pip...

In silico detection of a candidate disease-associated microorganism in metagenomic data from otter clams (Lutraria rhynchaena Reeve, 1854) affected by swollen siphon disease

Swollen siphon disease causes substantial mortality and economic losses in farmed snout otter clams (Lutraria rhynchaena) in Vietnam, yet its causative agent remains unknown. In this study, we performed metagenomic assembly and reconstructed metagenome-assembled genomes (MAGs) fr...

Permeability effect on heat transfer and flow dynamics past two tandem 45°-inclined square cylinders

In this study, two-dimensional transitional flow and convective heat transfer past two tandem porous square cylinders inclined at 45° are numerically investigated using the lattice Boltzmann method (LBM) at a Reynolds number ( R e ) of 150 and a Prandtl number ( P r ) of 0.71 acr...

New discoveries of Lanonia (Arecaceae) from northern Vietnam and southwestern China

Ground-Motion Models for 5% Damped PSA for Shallow Crustal Earthquakes in Northern Vietnam

ABSTRACT This study presents a ground-motion model (GMM) for Northern Vietnam (NVN). The reference global GMM given by Abrahamson et al. (2014; hereafter, ASK14) is regionalized to NVN using a local data set that contained data recorded at 83 stations from 229 shallow crustal ear...

pH-responsive dual-layered chitosan/Tween 80 nanoemulsions for gastrointestinal targeted delivery of curcumin

Abstract Curcumin's application is severely hindered by its hydrophobicity, poor solubility and rapid degradation. This study developed a pH-responsive, dual-layered curcumin-chitosan nanoemulsion (nCCURs) system using the phase inversion temperature method coupled with probe ult...

Magneto-inductive waveguiding using a step-defect line in a reconfigurable digital metasurface for wireless power transmission

Abstract In this paper, we present a reconfigurable digital two-dimensional metasurface consisting of an 8 × 8 matrix of specialized unit cells that can dynamically switch between two resonance modes at 11 MHz and 13.56 MHz. By carefully designing defect-based metamaterial caviti...
