Numerical study of the coupling between reaction and mass transfer for liquid-liquid slug flow in square microchannels [PDF]
, 2010 While the benefits of miniaturisation on processes have been widely demonstrated, its impact on microfluidics and local mechanisms such as mass transfer is still little understood.

Tau acetylation at K331 has limited impact on tau pathology in vivo
FEBS Letters, EarlyView.We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Calpain small subunit homodimerization is robust and calcium‐independent
FEBS Letters, EarlyView.Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Liquid-liquid extraction of cerium using synergist extractant
Journal of Mechanical Engineering and Sciences, 2018 This work studies on the performance of synergist extractants on the extraction of Cerium (Ce) alone. Conventional extractant, 4,4,4-trifluoro-1-(2-thienyl)-1,3- butanedione (HTTA) was combined with 3-methylimidazolium bis(triflouromethylsulfonyl)imide [

Pitfall in the high-throughput quantification of whole blood cyclosporin A using liquid chromatography-tandem mass spectrometry [PDF]
, 2005 In a growing number of laboratories the technique of liquid chromatography-tandem mass spectrometry is used for the quantification of cyclosporin A in whole blood, employing cyclosporin D as the internal standard. Cyclosporin A is extensively metabolized
