Alzheimer's disease (AD) is the most frequent neurodegenerative disorder worldwide. The great variability in evolution and incomplete understanding of molecular mechanisms underlying AD make it difficult to predict when a patient will convert from prodromal stage dementia. We hypothesize that metabolic alterations present at level brain could be reflected systemic blood serum patients, these used as prognostic biomarkers. This pilot study proposes investigation via nuclear magnetic resonance (NMR) spectroscopy consecutive series patients including 57 affected by dementia (AD-dem) 45 with mild cognitive impairment (MCI) due (MCI-AD). As control group, we considered 31 subjects whom other disorders were excluded (MCI). A panel 26 metabolites 112 lipoprotein-related parameters was quantified logistic LASSO regression algorithm employed identify optimal combination metabolites-lipoproteins their ratios discriminate groups interest.

With its high resolving power and sensitivity, mass spectrometry is considered the most informative technique for metabolite qualitation quantification in plant sciences. However, spatial location information, which crucial exploration of physiological mechanisms, lost. Mass imaging (MSI) able to visualize distribution a large number metabolites from complex sample surface single experiment. In this paper, flexible low-cost laser desorption-dielectric barrier discharge ionization-MSI (LD-DBDI-MSI) platform was constructed by combining an LD system with in-line DBDI source, high-precision translation stage, ambient spectrometer. It can be operated at resolution 20 μm atmospheric environment requires minimal preparation. This study presents images in-situ metabolic profiling two kinds plants different origins, wild farmed

A combination of pathway enrichment and metabolite clustering analysis is used to interpret untargeted 1H NMR metabolomics data, enabling a biochemically informative comparison the effects induced by panel known cytotoxic gold(I) gold(III) compounds in A2780 ovarian cancer cells. The identification most dysregulated pathways for major classes highlights specific chemical features that lead common biological effects. proposed approach may have broader applicability screening metal-based drug candidate libraries, which always complicated their multitarget nature, support comprehensive interpretation metabolic actions.

COVID-19 infection has revealed significant effects on the human blood metabolome and lipoproteome, which have been coherently observed in different cohorts worldwide across various waves of SARS-CoV-2 pandemic. As one main clinical manifestations is a severe acute respiratory illness, it pertinent to explore whether this metabolic/lipoproteomic disturbance associated with symptoms. To purpose we are here reporting comparative1H NMR analyses plasma 252 patients non-COVID-19 interstitial (24 individuals) or lobar (21 pneumonia, all matched by age, gender disease severity. The analysis based 24 metabolites 114 lipoprotein parameters. Several common traits among three groups, albeit some peculiar features characteristic each group. differences were between cases others.

Ischemic stroke is a leading cause of disability and mortality, particularly among the elderly. Recanalization therapies, including thrombolysis thrombectomy, are essential for restoring blood flow saving ischemic tissue. However, these interventions may trigger reperfusion injury, worsening inflammation tissue damage, to blood-brain-barrier (BBB) disruption, cerebral edema (CE) adverse functional outcomes. Here we propose model integrating circulating inflammatory biomarkers with metabolomic lipoproteomic data able help clinicians in predicting BBB CE at 24 h post onset poor post-stroke outcome (Modified Rankin Scale (mRS > 2). Peripheral from 87 patients was collected admission after onset.

A major challenge in 1D 1H NMR-based metabolomics studies is the occurrence of slight shifts resonances mixture compounds compared to reference spectra spectral databases due variations buffer conditions, temperature, and matrix effects. This hampers both automated deconvolution metabolite quantification crowded regions NMR complex mixtures whose analysis particularly susceptible such 2D metabolomics, on other hand, substantially more robust but also much demanding terms spectrometer time. Here we introduce an approach, termed COLMAR1d2d, which uses selected 1H-13C HSQC 1H-1H TOCSY a subset samples along with all overcome this bottleneck. It relies our platform COLMARm using measured for representative unambiguously comprehensively determine composition exact peak positions identified under sample conditions present. information then used update database potentially large cohort COLMAR1d platform. demonstrated how synergistic combination allows significantly larger number metabolites than would be possible alone. Moreover, COLMAR1d2d improves quantitation, as from mouse urine Pseudomonas aeruginosa biofilm.
