Mass spectrometry indicates malignant potential

Potential of electrospray mass spectrometry for quantifying glycohemoglobin.

An electrospray ionization-mass spectrometric procedure has been developed for determining glycohemoglobin. Whole-blood samples from 78 diabetic and 50 nondiabetic subjects (glycation range 3-15%, as determined by electrospray mass spectrometry) were diluted 500-fold in an acidic denaturing solvent and introduced directly into a mass spectrometer. The resulting mass spectra were then processed ...

On the potential of Raman-spectroscopy-based carbonate mass spectrometry

The potential for using Raman spectroscopy to measure stable oxygen isotope ratios (O/O) in carbonates is evaluated by measuring the Raman spectra and isotope ratios of a suite of 60 synthesized, O-enriched calcite crystals ranging in composition from natural abundance (0.2mole-% O) to 1.2 mole-% O.We determined the Raman-inferred isotopic ratios (RRaman) by fitting curves to the n1 symmetric s...

Mass spectrometry for the detection of potential psychiatric biomarkers

The search for molecules that can act as potential biomarkers is increasing in the scientific community, including in the field of psychiatry. The field of proteomics is evolving and its indispensability for identifying biomarkers is clear. Among proteomic tools, mass spectrometry is the core technique for qualitative and quantitative identification of protein markers. While significant progres...
