Khaja Muneeruddin of the University of Massachusetts Medical School will present the first talk in this session, titled “Quantifying the Neuromolecular Phenotype of Murine GM1 Gangliosidosis with Mass Spectrometry Imaging and Region of Interest Analysis.” This presentation will discuss region of interest analysis from MALDI imaging to elucidate molecular pathology in GM1 gangliosidosis.
The session’s next presentation will be given by Elizabeth Randall of Brigham and Women’s Hospital, Harvard Medical School, and is titled “Mapping Metabolism in Glioblastoma with MALDI MSI.” Randall’s presentation will describe MALDI MS imaging of lipids and metabolites in patient-derived xenograft models of glioblastoma.
Next, Michelle Reyzer of Vanderbilt University will present a talk titled “Visualizing the Distribution of Anti-Retroviral Agents in Sheep Vaginal Tissue by Imaging Mass Spectrometry.” Her research with imaging MS involved assessing drug compound distribution after topical delivery.
The next talk will be given by Peter Verhaert of M4i Maastricht Multimodal Molecular Imaging Institute, Maastricht, Netherlands. It is titled “Top-Down Mass Spectrometry Imaging of Endogenous Secretory Peptides in Clinical Human FFPE Material of Many Years Old with Immunohistochemical Validation.” His talk will discuss the imaging of human neuropeptides in clinical formalin-fixed paraffin-embedded (FFPE) tissue using a fully integrated microscope–MALDI ion trap TOF system.
Then, Amina Woods of NIDA-IRP, NIH (Baltimore) will present a talk titled “How Innovative Imaging MS Approaches Shed Light on What Happens in Traumatic Brain Injury.” Her research involves the use of MS imaging to assay lipid changes in traumatic brain injury and evaluate the efficacy of a peptide agonist.
The final presentation in the session, “Development of a Dual Imaging Strategy Combining Radio- and Mass Spectrometry-Imaging to Study the Biodistribution of 14C-Graphene Oxide,” will be given by Hélène Cazier of Université Paris Saclay, MetaboHUB. Her talk will discuss the combination of the two techniques for spatially resolved and quantitative analysis of graphene nanoparticles.
Paraben Exposure and Childhood Obesity Risk in Preschoolers: UPLC-MS/MS Insights from Recent Study
July 14th 2025Researchers speculating that exposure to paraben in early childhood is associated with changes in satiety hormones performed analysis of urinary methyl, ethyl, propyl, and butylparaben (MeP, EtP, PrP, BuP) levels in 4–6-year-old children, using ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS).
GC-MS Sheds Light on Chemical Communication Between Desert Locusts
July 9th 2025A multinational research team used behavioral assays and gas chromatography-mass spectrometry (GC-MS) to examine short- and long-term interactions between juvenile and adult desert locusts to test their hypothesis that cross-stage interactions influence juvenile cohesion and physiological traits.
