New research conducted usingmass spectrometers has providedinsight into key areas of strokeevaluation and treatment.Led byMingMing Ning, a clinical neurologistand researcher at the ClinicalProteomics Research Center atMassachusetts General Hospital(Boston, Massachusetts), the researchprovides potentially significant new insightinto patent foramen ovale (PFO) and itsconnection with strokes. PFO refers to acongenital heart abnormality, which leavesopen a passage between the left and rightsides of the heart, enabling blood clots totravel from the leg to the brain.
Strokes are the leading cause ofserious long-term disability in theUnited States, and with PFO affecting25% of the worldwide population,the potential health impacts aresignificant. Identification of potentialbiomarkers in mass spectrometrydata derived from the collaborativeresearch provides scientists withnew insights into how PFO can berelated to strokes. If confirmed,these insights may be important inhelping doctors to select the mostappropriate treatment for individualPFO stroke patients.
The research, conductedby Thermo Fisher Scientific’sBiomarker Research Initiativesin Mass Spectrometry Center incollaboration with MassachusettsGeneral Hospital, Harvard University,has also led to potential insightsin the understanding of tissueplasminogen activator (tPA) instroke treatment. tPA is a drugthat can be safely administeredonly within a very short windowof time after stroke symptomsoccur. The treatment, whichworks by dissolving blood clots,has proven highly effective, butinvolves significant risks. Only 5%of patients fit the timeframe criteriawithin which it is safe to administertPA. Through the use of massspectrometry–based proteomicsworkflows, data from the researchmay help scientists identify a widerscope of patients who might benefitfrom tPA.

This column shows that a Raman plate reader paired with partial least squares regression can simultaneously quantify glucose, fructose, sucrose, and ethanol in yeast fermentation samples, using turbidity-matched calibration standards to correct for yeast-induced turbidity, and offers a rapid, label-free, high-throughput method for tracking sugar consumption and ethanol production in strain screening, media optimization, and process development.
This column, the second installment on highly substituted benzene rings, shows that tri- and tetra-substituted substitution patterns can be distinguished by whether the ring bending peak is present and by the position of the in-phase aryl C-H wagging peak, which shifts according to how many adjacent hydrogens the ring carries.
