Abstract Introduction The diagnosis of COVID-19 is normally based on the qualitative detection viral nucleic acid sequences. Properties host response are not measured but key in determining outcome. Although metabolic profiles well suited to capture state, most metabolomics studies either underpowered, measure only a restricted subset metabolites, compare infected individuals against uninfected control cohorts that suitably matched, or do provide compact predictive model. Objectives Here we well-powered, untargeted assessment 120 patient samples acquired at hospital admission. study aims predict patient’s infection severity (i.e., mild severe) and potential outcome discharged deceased). Methods High resolution UHPLC-MS/MS analysis was performed serum using both positive negative ionization modes. A 20 intermediary metabolites were selected univariate statistical significance multiple predictor Bayesian logistic regression model created. Results predictors for their relevant biological function include deoxycytidine ureidopropionate (indirectly reflecting load), kynurenine (reflecting inflammatory response), short chain acylcarnitines (energy metabolism) among others. Currently, this approach predicts with Monte Carlo cross validated area under ROC curve 0.792 (SD 0.09) 0.793 0.08), respectively. blind validation an additional 90 patients predicted AUC 0.83 (CI 0.74–0.91) 0.76 0.67–0.86). Conclusion Prognostic tests markers discussed paper could allow improvement planning treatment.

Metabolomics uses advanced analytical chemistry techniques to enable the high-throughput characterization of metabolites from cells, organs, tissues, or biofluids. The rapid growth in metabolomics is leading a renewed interest metabolism and role that small molecule play many biological processes. As result, traditional views as being simply “bricks mortar” cells just fuel for cellular energetics are upended. Indeed, appear have much more varied far important roles signaling molecules, immune modulators, endogenous toxins, environmental sensors. This review explores how yielding new insights into number physiological In particular, major focus on illustrating discoveries made through improving our understanding both normal physiology pathophysiology diseases. These influence organ function, nutrient sensing, gut physiology. Collectively, this work unified system-wide perspective biology wherein metabolites, proteins, genes understood interact synergistically modify actions functions organelles, organisms.

Human blood is a self-regenerating lipid-rich biological fluid that routinely collected in hospital settings. The inventory of lipid molecules found plasma (plasma lipidome) offers insights into individual metabolism and physiology health disease. Disturbances the lipidome also occur conditions are not directly linked to metabolism; therefore, lipidomics based on MS an emerging tool array clinical diagnostics disease management. However, challenges exist translation such lipidomic data applications. These relate reproducibility, accuracy, precision quantitation, study design, sample handling, sharing. This position paper emerged from workshop initiated community-led process elaborate define set generally accepted guidelines for quantitative MS-based or serum, with harmonization acquired different instrumentation platforms across independent laboratories as ultimate goal. We hope other fields may benefit follow precedent.

Large-scale suspect and non-targeted screening approaches based on high-resolution mass spectrometry (HRMS) are today available for chemical profiling holistic characterisation of biological samples. These advanced techniques allow the simultaneous detection a large number features, including markers human exposure. Such interest biomonitoring, environmental health studies support to risk assessment. Furthermore, these have promising capability detect chemicals emerging concern (CECs), document extent exposure, generate new research hypotheses provide early warning policy. Whilst growing importance in environment food safety areas, respectively, CECs remain poorly addressed field biomonitoring. This shortfall is due several scientific methodological reasons, global lack harmonisation. In this context, main aim paper present an overview basic principles, promises challenges applied samples as specific introduce major specificities compared other fields. Focused liquid chromatography coupled HRMS-based data acquisition methods, addresses all steps analytical workflows.

Adverse environmental conditions due to climate change, combined with declining soil fertility, threaten food security. Modern agriculture is facing a pressing situation where novel strategies must be developed for sustainable production and Biostimulants, conceptually defined as non-nutrient substances or microorganisms the ability promote plant growth health, represent potential provide economically favorable solutions that could introduce approaches improve agricultural practices crop productivity. Current knowledge phenotypic observations suggest biostimulants potentially function in regulating modifying physiological processes plants growth, alleviate stresses, quality yield. However, successfully develop biostimulant-based formulations programs, understanding biostimulant-plant interactions, at molecular, cellular levels, prerequisite. Metabolomics, multidisciplinary omics science, offers unique opportunities predictively decode mode of action on plants, identify signatory markers biostimulant action. Thus, this review intends highlight current scientific efforts gaps research industry, context promotion stress responses. The firstly revisits models have been elucidated describe molecular machinery employed by coping stresses. Furthermore, definitions, claims applications are pointed out, also indicating lack biological basis accurately postulate mechanisms biostimulants. articulates briefly key aspects metabolomics workflow (potential) science industry.
