Degradation mechanism of the von Willebrand factor A2 domain by nattokinase
FEBS Letters, EarlyView.Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Investigation on the Separation Performance of a Multicyclone Separator for Natural Gas Purification
Aerosol and Air Quality Research, 2014 This study evaluated the separation efficiency and developed a pressure drop model for a multicyclone separator used for natural gas purification. The collection and grade efficiencies of a multicyclone separator with 15 single cyclone separators were evaluated at inlet velocities of 6–24 m/s and particle concentrations of 30–2000 mg/m 3 at atmospheric

FEBS Letters, EarlyView.An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Effect of Aerosol Loading on Separation Performance of PM2.5 Cyclone Separators
Aerosol and Air Quality Research, 2018 The adverse health effects of particulate matter less than 2.5 µm in diameter (PM2.5) have drawn increasing attention over the past several decades. To obtain reliable measurements, it is critical to efficiently separate PM2.5 in the airstream from the beginning till the end of sampling.
