For the first time, activated carbon from a durian shell (ACDS) activated by HSO was successfully synthesized in the present study. The fabricated ACDS has a porous surface with a specific surface area of 348.0017 m·g, average capillary volume of 0.

The formation mechanism of MSCSFZ was proposed, in which FeO nanoparticles served as a template for supporting and anchoring the ZnO crystal layer as the shells. The morphology of MSCSFZ can be varied from spherical to rice seed-like structures, and the bandgap was able to be narrowed down to 2.

The mortality rate observed in non-medicated groups of co-infected fish (93.
View Article and Find Full Text PDFOysters are widely distributed worldwide, but are mainly concentrated in tropics and subtropics. Total lipid (TL), fatty acid (FA) composition of TL and polar lipid (PoL) fractions, phospholipid (PL) class, and molecular species composition in soft tissues of Crassostrea lugubris were investigated for the first time from Vietnam. Phosphatidylglycolic acid (PGA) is the new phospholipid class first identified in marine species in general and Crassostrea lugubris in particular.

The compounds were experimentally isolated, structurally elucidated, and tested in vitro for their inhibition effects on tyrosine phosphatase 1B (PTP1B) and α-glucosidase (3W37). Density functional theory and molecular docking techniques were utilized as computational methods to predict the stability of the ligands and simulate interaction between the studied inhibitory agents and the targeted proteins.

Decne. 3-thunberginol C 6---D-glucopyranoside was determined as a mixture of boat-like conformers based on NMR evidence and density functional theory (DFT) calculations.

The conversion of isoflavones into aglycones via fermentation of soybean products is often realized by β-glucosidase, an enzyme produced by fungi. In this study, a filamentous fungus, , was isolated from root of Turcz, which was able to produce the highest activity of β-glucosidase up to 33.

In the province of Dac Lac, where potential malaria exposure begins at birth, 57 subjects (mean age, 9.6 years) were randomized to receive artesunate-chloroquine (group 1) or artesunate-sulfadoxine-pyrimethamine (group 2).
