Special Issue Information

Dear Colleagues,

Metabolomics field embodies a significant share of omics sciences, aiming at the chemical characterization of complex biological matrices through bioanalytical platforms such as nuclear magnetic resonance (NMR). Over the last few decades, both solution and high-resolution magic angle spinning (HR-MAS) NMR technologies have proven to be valuable for the detection as well as quantitation of various chemical entities (i.e., biomarkers) in biofluids, tissues, cells, etc., towards the prognosis and/or diagnosis of several diseases. The simplicity of NMR samples’ preparation, including its non-destructive nature as well as the impeccable reproducibility of NMR data, allow for the detection of unique signatures from pathological conditions, turning the whole NMR profile into a collective biomarker. The successful application of both targeted and untargeted NMR-based metabolomics in biomedicine is the consequence of the continuous advancements in NMR technology/methods/bioinformatics tools, which led to fully automated high-throughput analyses and data interpretation.

This Special Issue will highlight the recent developments in both experimental and computational methods of NMR/HR-MAS technologies in metabolomics combined with their application/validation on real-world samples from pathological conditions. In general, the present Special Issue is designed to cover all NMR/HR-MAS novel strategies (i.e., both experimental and computational methods/tools) for metabolomics studies, aiming at the detection of novel biomarkers for disease diagnosis and/or prognosis. The exploration of any disease metabolic profile via NMR-based approaches will also be considered. Submissions of original research as well as perspective articles are welcome.

Metabolomic biomarkers hold promise in aiding the diagnosis and prognostication of traumatic brain injury. In Canada, over 165,000 individuals annually suffer from a traumatic brain injury (TBI), making it one of the most prevalent neurological conditions. In this pilot investigation, we examined blood-derived biomarkers as proxy measures that can provide an objective approach to TBI diagnosis and monitoring. Using a 1H nuclear magnetic resonance (NMR)-based quantitative metabolic profiling approach, this study determined whether (1) blood-derived metabolites change during recovery in male participants with mild to severe TBI; (2) biological pathway analysis reflects mechanisms that mediate neural damage/repair throughout TBI recovery; and (3) changes in metabolites correlate to initial injury severity. Eight male participants with mild to severe TBI (with intracranial lesions) provided morning blood samples within 1–4 days and again 6 months post-TBI. Following NMR analysis, the samples were subjected to multivariate statistical and machine learning-based analyses. Statistical modelling displayed metabolic changes during recovery through group separation, and eight significant metabolic pathways were affected by TBI. Metabolic changes were correlated to injury severity. L-alanine (R= −0.63, p < 0.01) displayed a negative relationship with the Glasgow Coma Scale. This study provides pilot data to support the feasibility of using blood-derived metabolites to better understand changes in biochemistry following TBI. Full article
