Article Abstract
Background: The interactions of polytrauma, shock, and traumatic brain injury (TBI) on thromboinflammatory responses remain unclear and warrant investigation as we strive towards personalized medicine in trauma. We hypothesized that comprehensive omics characterization of plasma would identify unique metabolic and thromboinflammatory pathways following TBI.
Methods: Patients were categorized as TBI vs Non-TBI, and stratified into Polytrauma or minimally injured. Discovery 'omics was employed to quantify the top differently expressed proteins and metabolites of TBI and Non-TBI patient groups.
Results: TBI compared to Non-TBI showed gene enrichment in coagulation/complement cascades and neuronal markers. TBI was associated with elevation in glycolytic metabolites and conjugated bile acids. Division into isolated TBI vs polytrauma showed further distinction of proteomic and metabolomic signatures.
Conclusion: Identified mediators involving in neural inflammation, blood brain barrier disruption, and bile acid building leading to TBI associated coagulopathy offer suggestions for follow up mechanistic studies to target personalized interventions.

A multi-omics recovery factor predicts long COVID in the IMPACC study.

Background: Following SARS-CoV-2 infection, ~10-35% of COVID-19 patients experience long COVID (LC), in which debilitating symptoms persist for at least three months. Elucidating biologic underpinnings of LC could identify therapeutic opportunities.
Methods: We utilized machine learning methods on biologic analytes provided over 12-months after hospital discharge from >500 COVID-19 patients in the IMPACC cohort to identify a multi-omics "recovery factor", trained on patient-reported physical function survey scores.

Goat milk is prized for its nutritional value, but the illegal addition of δ-decanolactone to enhance flavor poses risks to product integrity and safety. This study employed a tripartite multi-omics framework integrating metabolomics, lipidomics, and proteomics, combined with FTIR and CLSM to systematically elucidate the multifaceted effects of δ-decanolactone on goat milk. Chemometric and bioinformatic pipelines identified dysregulated molecules and pathways, while molecular docking validated interactions with key targets.

Plasma proteomics has regained attention in recent years through advancements in mass spectrometry instrumentation and sample preparation as well as new high-throughput affinity-based technologies. Here, we evaluate the analytical performance of the new Olink Reveal platform, a proximity extension assay (PEA)-based technology quantifying 1034 proteins and covering many biological pathways, in particular immune system processes. Using spiked-in recombinant Interleukin-10 (IL-10) and vascular endothelial growth factor D (VEGF-D) in the NIST SRM 1950 plasma standard, we assessed the linearity, sensitivity, precision, and accuracy of the Olink Reveal assay.

In mammals, chromosome-wide regulatory mechanisms ensure a balance of X-linked gene dosage between males (XY) and females (XX). In female cells, expression of genes from one of the two X chromosomes is curtailed, with selective accumulation of Xist-RNA, Xist-associated proteins, specific histone modifications (for example, H3K27me3) and Barr body formation observed throughout interphase. Here we show, using chromosome flow-sorting, that during mitosis, Xist-associated proteins dissociate from inactive X (Xi) chromosomes, while high levels of H3K27me3 and increased compaction of the Xi relative to active X (Xa), are retained.

Background: Despite successful mechanical thrombectomy (MT), approximately 50% of patients with large vessel occlusion (LVO) stroke experience poor outcomes due to reperfusion injury. Intra-arterial infusion of human serum albumin (HSA) may offer neuroprotective benefits; however, its safety and feasibility have not been established when delivered via the internal carotid artery. In this study we aimed to evaluate the safety and technical feasibility of HSA infusion through the guiding catheter placed during MT in patients with anterior circulation LVO stroke following successful reperfusion.
