Water Circulation and Marine Environment in the Antarctic Traced by Speciation of 129I and 127I

open access: yesScientific Reports, 2017
Emissions of anthropogenic 129I from human nuclear activities are now detected in the surface water of the Antarctic seas. Surface seawater samples from the Drake Passage, Bellingshausen, Amundsen, and Ross Seas were analyzed for total 129I and 127I, as ...

Economics of tandem mass spectrometry screening of neonatal inherited disorders [PDF]

open access: yes, 2006
Objectives: The aim of this study was to evaluate the cost-effectiveness of neonatal screening for phenylketonuria (PKU) and medium-chain acyl-coA dehydrogenase (MCAD) deficiency using tandem mass spectrometry (tandem MS). Methods: A systematic review

BLINK enables ultrafast tandem mass spectrometry cosine similarity scoring

open access: yesScientific Reports, 2023
Metabolomics has a long history of using cosine similarity to match experimental tandem mass spectra to databases for compound identification. Here we introduce the Blur-and-Link (BLINK) approach for scoring cosine similarity.

Sucrose gradient chromatin enrichment for quantitative proteomics analysis in budding yeast

open access: yesSTAR Protocols, 2021
Summary: Here, we describe a fractionation protocol optimized to quantify changes in relative abundance of the chromatin-bound proteome (chromatome) by tandem mass tag multiplexing-based tandem mass spectrometry. It has been applied to yeast cells before

Seminolipid and its precursor/degradative product, galactosylalkylacylglycerol, in the testis of saposin A- and prosaposin-deficient mice

open access: yesJournal of Lipid Research, 2003
Sphingolipid activator proteins (saposins A, B, C, and D) are derived from a common precursor protein (prosaposin) and specifically activate in vivo degradation of glycolipids with short carbohydrate chains.

Quantification of voriconazole in plasma by liquid chromatography-tandem mass spectrometry [PDF]

open access: yes, 2005
A convenient liquid chromatography-tandem mass spectrometry method for the quantification of the triazole antifungal agent voriconazole in plasma samples is described. Fenbuconazole is used as an internal standard.

From sequence-defined macromolecules to macromolecular pin codes [PDF]

open access: yes, 2020
Dynamic sequence-defined oligomers carrying a chemically written pin code are obtained through a strategy combining multicomponent reactions with the thermoreversible addition of 1,2,4-triazoline-3,5-diones (TADs) to indole substrates.

Gas-Phase Fragmentation of Cyclic Oligosaccharides in Tandem Mass Spectrometry

open access: yesMolecules, 2019
Modern mass spectrometry, including electrospray and MALDI, is applied for analysis and structure elucidation of carbohydrates. Cyclic oligosaccharides isolated from different sources (bacteria and plants) have been known for decades and some of them ...
