Methyl labeling and TROSY NMR spectroscopy of proteins expressed in the eukaryote Pichia pastoris
Abstract13C Methyl TROSY NMR spectroscopy has emerged as a powerful method for studying the dynamics of large systems such as macromolecular assemblies and membrane proteins. Specific 13C labeling ofExpand

Bulk derivatization and cation exchange restricted access media-based trap-and-elute liquid chromatography-mass spectrometry method for determination of trace estrogens in serum.
Estrone (E1), estradiols (α/β-E2), and estriol (E3) are four major metabolically active estrogens exerting strong biological activities at very low circulating concentrations. This paper reports aExpand

Algal and archaeal polyisoprenoids in a recent marine sediment: Molecular isotopic evidence for anaerobic oxidation of methane
[1] Analyses of 13C contents of individual organic molecules in a marine sediment show that crocetane, 2,6,11,15-tetramethylhexadecane, an isomer of phytane, is produced by microorganisms that useExpand

Bioleaching of rare earth elements from bastnaesite-bearing rock by actinobacteria
Abstract Biological leaching of rare earth elements (REEs) from low-grade ores and mine tailings represents a potentially cost-effective green technology for REE recovery, yet the specific mechanismsExpand

Targeted quantification of lipid mediators in skeletal muscles using restricted access media-based trap-and-elute liquid chromatography-mass spectrometry.
Lipid mediators (LMs) are a class of bioactive metabolites of the essential polyunsaturated fatty acids (PUFA), which are involved in many physiological processes. Their quantification in biologicalExpand

Chromatographic separation of racemic praziquantel and its residual determination in perch by LC-MS/MS.
An enantioselective depletion study of praziquantel (PZQ) in perch muscle was done using a simple, sensitive and specific liquid chromatography-tandem mass spectrometry (LC-MS/MS) method. Two cyclicExpand

Quantification of aminobutyric acids and their clinical applications as biomarkers for osteoporosis
Osteoporosis is a highly prevalent chronic aging-related disease that frequently is only detected after fracture. We hypothesized that aminobutyric acids could serve as biomarkers for osteoporosis.Expand

Reactions of Vinyl Chloride and Methanol in a Quadrupole Ion Trap Mass Spectrometer during VOC Analysis
A reaction between vinyl chloride and the solvent (methanol) was observed during volatile organic compound (VOC) analysis on a gas chromatograph/quadrupole ion trap mass spectrometer (GC/MS). AExpand
