Thioglycerol matrix interactions in the positive ion fast atom bombardment mass spectrometry of several Hantzsch and Biginelli ester derivatives of boronic acids
31-05-2013 | Joel Martínez, Vida Abarca, F. Javier Pérez, Vladimir Carranza, René Miranda, Rapid Communications in Mass Spectrometry, 2013
RATIONALE Fast atom bombardment (FAB) ionization is a valuable tool for analyzing non‐volatile or thermally labile compounds when harder ionization methods (EI or CI) have been unsuccessful. Unexpected interactions between matrix and analyte may, however, occur in FAB ionization leading ...
Matrix‐assisted laser desorption/ionization for simultaneous quantitation of (acyl‐)carnitines and organic acids in dried blood spots
31-05-2013 | Katharina M. Ostermann, Rebecca Dieplinger, Nikola M. Lutsch, Kerstin Strupat, Thomas F. Metz, Thomas P. Mechtler, D ..., Rapid Communications in Mass Spectrometry, 2013
RATIONALE Screening for inborn errors of metabolism using mass spectrometry is part of nationwide newborn screening programs and involves the detection of disease relevant (acyl‐)carnitines and organic acids from dried blood spots. Matrix‐Assisted Laser Desorption/Ionization Mass ...
High‐temperature mass spectrometric study of the vaporization processes and thermodynamic properties of melts in the PbO‐B2O3‐SiO2 system
31-05-2013 | V. L. Stolyarova, S. I. Lopatin, A. L. Shilov, S. M. Shugurov, Rapid Communications in Mass Spectrometry, 2013
RATIONALE The unique properties of the PbO‐B2O3‐SiO2 system, especially its extensive range of glass‐forming compositions, make it valuable for various practical applications. The thermodynamic properties and vaporization of PbO‐B2O3‐SiO2 melts are not well established so far and the data ...
Structural elucidation of two types of novel glycosphingolipids in three strains of Skeletonema by liquid chromatography coupled with mass spectrometry
31-05-2013 | Fang Zhao, Jilin Xu, Juanjuan Chen, Xiaojun Yan, Chengxu Zhou, Shuang Li, Xiaoyan Xu, Fangting Ye, Rapid Communications in Mass Spectrometry, 2013
RATIONALE Glycosphingolipids (GSLs) are important components of the cell membrane; however, little is known about GSLs in microalgae. We analyzed GSLs in three strains of Skeletonema microalgae by liquid chromatography coupled with mass spectrometry. METHODS Total lipid was ...
Screening calmodulin‐binding ligands using intensity‐fading matrix‐assisted laser desorption/ionization mass spectrometry
31-05-2013 | Lei Ma, Zhaofu Wang, Shu Liu, Fengrui Song, Zhiqiang Liu, Shuying Liu, Rapid Communications in Mass Spectrometry, 2013
RATIONALE Calmodulin (CaM) plays an important role in the regulation of metabolism, cytoskeleton and cell proliferation. CaM antagonists are a class of drugs that can bind to CaM and modulate the interactions between CaM and their target biological processes. Screening new calmodulin ...
An enhanced technique for automated determination of 15N signatures of N2, (N2+N2O) and N2O in gas samples
31-05-2013 | Dominika Lewicka‐Szczebak, Reinhard Well, Anette Giesemann, Lena Rohe, Ulrike Wolf, Rapid Communications in Mass Spectrometry, 2013
RATIONALE An enhanced analytical approach for analyzing gaseous products from 15N‐enriched pools has been developed. This technique can be used to quantify nitrous oxide (N2O) and dinitrogen (N2) fluxes from denitrification. It can also help in distinguishing different N2‐ and N2O‐forming ...
High‐throughput determination of cortisol, cortisone, and melatonin in oral fluid by on‐line turbulent flow liquid chromatography interfaced with liquid chromatography/tandem mass spectrometry
31-05-2013 | Silvia Fustinoni, Elisa Polledri, Rosa Mercadante, Rapid Communications in Mass Spectrometry, 2013
RATIONALE Cortisol, cortisone, and melatonin (CORTol, CORTone, and MELA, respectively) are hormones related to stress and sleep disorders. Their detection is relevant to epidemiological studies aimed at investigating the effects of circadian cycle disruption. The aim of this study was to ...
Electric‐field‐enhanced collection of laser‐ablated materials onto a solvent bridge for electrospray ionization mass spectrometry
31-05-2013 | Eric Kaufman, Whitney Smith, Matthew Kowalski, Iwona Beech, Jan Sunner, Rapid Communications in Mass Spectrometry, 2013
RATIONALE Ambient imaging mass spectrometry methods are critically dependent on the ability to efficiently collect all substances from a well‐defined area of the sample. Improvements in this area are critical and enabling. METHODS Methods for the efficient collection of ...
δ13C analysis of amino acids in human hair using trimethylsilyl derivatives and gas chromatography/combustion/isotope ratio mass spectrometry
21-05-2013 | Yan An, Zeland Schwartz, Glen P. Jackson, Rapid Communications in Mass Spectrometry, 2013
RATIONALE To provide a simple one‐step derivatization procedure for the analysis of a wide variety of amino acids in human hair by gas chromatography/combustion/isotope ratio mass spectrometry (GC/C/IRMS). N,O‐Bis(trimethylsilyl)trifluoroacetamide (BSTFA) derivatization is already widely ...
