MetabolomicsAnalyze the metabolic characteristics in fecal and peripheral blood plasma samples from different patient populations_blood

Given that hepatitis B virus (HBV)-related hepatocellular carcinoma (HBV-HCC) exhibits unique gut microbial and metabolic characteristics that influence the immunosuppressive tumor microenvironment, a better understanding of the correlations among gut microbiota, metabolism, and immunosuppressive...

MetabolomicsAn LC-MS untargeted metabolomic comparison between three blood microsampling devices, whole blood, and plasma

Blood microsampling (BµS) devices collect less than 100 µL of blood, offering a less invasive and more cost-effective alternative to venipuncture. However, its metabolomic comparability to conventional samples remains unclear, and standardized BµS metabolomic workflows are lacking. This study com...

MetabolomicsMetabolome profiling by untargeted metabolomics and biomarker panel selection using machine-learning for patients in different stages of peripheral neuropathy induced by oxaliplatin

Background: Oxaliplatin-induced peripheral neuropathy (OIPN) poses a significant challenge for patients with colorectal tumor, often resulting in treatment interruption or discontinuation and subsequent treatment failure. Herein, a longitudinal untargeted metabolomic study to reveal the metabolom...

MetabolomicsIndividual variability in human blood metabolites identifies age-related differences (30 persons, whole blood data)
Metabolites present in human blood document individual physiological states influenced by genetic, epigenetic, and lifestyle factors. Using high-resolution liquid chromatography-mass spectrometry (LC-MS), we performed nontargeted, quantitative metabolomics analysis in blood of 15 young (29 ± 4 y of ...

MetabolomicsIndividual variability in human blood metabolites identifies age-related differences - constant blood metabolite levels during 24h in 4 individuals
Metabolites present in human blood document individual physiological states influenced by genetic, epigenetic, and lifestyle factors. Using high-resolution liquid chromatography-mass spectrometry (LC-MS), we performed nontargeted, quantitative metabolomics analysis in blood of 15 young (29 ± 4 y of ...

MetabolomicsPeripheral modulation of antidepressant targets MAO-B and GABAAR by harmol induces mitohormesis and delays aging in preclinical models
Reversible and sub-lethal stresses to the mitochondria elicit a program of compensatory responses that ultimately improve mitochondrial function, a conserved anti-aging mechanism termed mitohormesis. Here, we show that harmol, a member of the beta-carbolines family with anti-depressant properties, i...

MetabolomicsWhole blood metabolomics of dementia patients reveal classes of disease-linked metabolites

Dementia is caused by factors that damage neurons. We quantified small molecular markers in whole blood of dementia patients, using non-targeted liquid chromatography-mass spectroscopy (LC-MS). Thirty-three metabolites, classified into 5 groups (A-E), differed significantly in dementia patients, ...

MetabolomicsIndividual variability in human blood metabolites identifies age-related differences (30 persons, plasma data)
Metabolites present in human blood document individual physiological states influenced by genetic, epigenetic, and life-style factors. Using high-resolution liquid chromatography-mass spectrometry (LC-MS), we performed non-targeted, quantitative metabolomics analysis in blood of 15 young (29±4 yr) a...
