Mechanistic Description of Photochemical Oligomer Formation from Aqueous Pyruvic Acid.

open access: yesJournal of Physical Chemistry A, 2017
The aqueous phase photochemistry of pyruvic acid, an important oxidation product of isoprene, is known to generate larger oligomeric species that may contribute to the formation of secondary organic aerosol in the atmosphere.

Reaction Engineering and Comparison of Electroenzymatic and Enzymatic ATP Regeneration Systems [PDF]

open access: yesarXiv, 2023
Adenosine-5'-triphosphate (ATP) plays a crucial role in many biocatalytic reactions and its regeneration can influence the performance of a related enzymatic reaction significantly. Here, we established an electrochemically coupled ATP regeneration by pyruvate oxidase and acetate kinase (ACK) for the phosphorylation of mevalonate catalyzed by ...

Aberrant glycosylation of IgG in children with active lupus nephritis alters podocyte metabolism and causes podocyte injury

open access: yesArthritis &Rheumatology, Accepted Article.
Background Podocytes are integral to the maintenance of the glomerular filtration barrier. Their injury results in proteinuria and disease progression in lupus nephritis (LN). Aberrant IgG glycosylation drives podocyte injury in LN and leads to cytoskeletal rearrangement, motility changes and decreased nephrin production.

Enabling liquid vapor analysis using synchrotron VUV single photon ionization mass spectrometry with a microfluidic interface. [PDF]

open access: yes, 2018
Vacuum ultraviolet (VUV) single photon ionization mass spectrometry (SPI-MS) is a vacuum-based technique typically used for the analysis of gas phase and solid samples, but not for liquids due to the challenge in introducing volatile liquids in a vacuum.
