Identification and characterization by electrospray mass spectrometry of endogenous Drosophila sphingadienes

Journal of Lipid Research, 2008
Sphingolipids comprise a complex group of lipids concentrated in membrane rafts and whose metabolites function as signaling molecules. Sphingolipids are conserved in Drosophila, in which their tight regulation is required for proper development and ...

Multienzyme (3‐in‐1)‐Mimicking a Single Nucleobase‐Derived Bionanozyme for Versatile Environmental and Biomedical Applications

Advanced Healthcare Materials, EarlyView.
This study reports the development of bioinspired 2D crystalline Bionanozyme derived from a single nucleobase. It effectively mimics multienzyme activity to detect and remove phenolic pollutants, identify disease biomarkers with high sensitivity, and protect cells from oxidative stress.

Electrospray ionization mass spectrometry of

Journal of the American Society for Mass Spectrometry, 2000
Lysoglycerophosphocholine lipids (lyso-GPC) are important intermediates in the synthesis and metabolism of glycerophosphocholine lipids which are major components of the cellular lipid bilayer. Significant differences in the collisional induced decomposition (CID) behavior were observed for each of the four different subtypes of lyso-GPC in both ...

Using High‐Throughput Screening to Identify Crosslinking Peptides That Control Cell‐Mediated Matrix Degradation

Advanced Healthcare Materials, EarlyView.
Protease‐degradable hydrogels mimic dynamic cell‐matrix interactions, but controlling hydrogel degradation is a challenge. We screen libraries of peptides to identify sequences that are primarily degraded by membrane‐localized proteases. Crosslinking hydrogels with these peptides enables cell to spread and migrate while reducing matrix degradation ...

Characterization of lead-phytochelatin complexes by nano-electrospray ionization mass spectrometry

Frontiers in Microbiology, 2012
The role of phytochelatins (PCn, metal-binding oligopeptides with the general structure (γGlu - Cys)n - Gly (n = 2- 11)) in metal detoxification is assumed to be based on immobilization of metals, which prevents binding of metals to important ...

Co-populated Conformational Ensembles of β(2)-Microglobulin Uncovered Quantitatively by Electrospray Ionization Mass Spectrometry [PDF]

, 2004
Ordered assembly of monomeric human β(2)-microglobulin (β(2)m) into amyloid fibrils is associated with the disorder hemodialysis-related amyloidosis. Previously, we have shown that under acidic conditions (pH

A Ship‐in‐a‐Bottle Strategy: Crosslinking Amines and Epoxides inside MOF Pores for Enhanced CO2 Capture Performance

Advanced Materials, EarlyView.
A “ship‐in‐a‐bottle” strategy is used to grow oligomers inside of a MOF by crosslinking alkylamines with epoxides within the pores of Cr‐BDC. When tested in postcombustion carbon capture applications, the composites show excellent performance with high CO2 adsorption capacity, exceptional CO2/N2 selectivity, and enhanced stability over 100 adsorption ...
