Mass Spectrometry Imaging. [PDF]

Anal Chem
Mass spectrometry imaging (MSI) maps the spatial distributions of chemicals on chemically complex surfaces. MSI offers unrivaled sensitivity and information density with each pixel comprising a mass spectrum. Over the past three decades, numerous technological developments have enabled MSI to evolve into a mainstream technique for untargeted molecular ...

Basal ganglia neuropeptides show abnormal processing associated with L-DOPA-induced dyskinesia

npj Parkinson's Disease, 2022
L-DOPA administration is the primary treatment for Parkinson’s disease (PD) but long-term administration is usually accompanied by hyperkinetic side-effects called L-DOPA-induced dyskinesia (LID). Signaling neuropeptides of the basal ganglia are affected

Comparison of Osteosarcoma Aggregated Tumour Models with Human Tissue by Multimodal Mass Spectrometry Imaging

Metabolites, 2021
Osteosarcoma (OS) is the most common primary bone malignancy and largely effects adolescents and young adults, with 60% of patients under the age of 25. There are multiple cell models of OS described in vitro that express the specific genetic alterations

Simultaneous mass spectrometry imaging of multiple neuropeptides in the brain and alterations induced by experimental parkinsonism and L-DOPA therapy

Neurobiology of Disease, 2020
Neuropeptides are important signalling molecules in the brain and alterations in their expression levels have been linked to neurological disorders such as Parkinson's disease. It is challenging to map neuropeptide changes across and within brain regions
