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...

TranscriptomicsWhole Blood Gene Expression Profiles Distinguish Patients with Single versus Recurrent Venous Thromboembolism
Venous thromboembolism (VTE) is a major cause of morbidity and mortality. Pulmonary embolism is a life threatening manifestation of VTE that occurs in at least half the patients on presentation. In addition, VTE recurs in up to 30% of patients after a standard course of anticoagulation, and there 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, ...

MetabolomicsFrailty markers comprise blood metabolites involved in antioxidation, cognition, and mobility
As human society ages globally, age-related disorders are becoming increasingly common. Due to decreasing physiological reserves and increasing organ system dysfunction associated with age, frailty affects many elderly people, compromising their ability to cope with acute stressors. Frail elderly pe...

TranscriptomicsWhole blood gene expression profiles distinguish clinical phenotypes of venous thromboembolism [Set1]
Recurrent venous thromboembolism (VTE) occurs infrequently following a provoked event but occurs in up to 30% of individuals following an initial unprovoked event. We studied 134 patients with VTE separated into 3 groups: (1) ‘low-risk’ patients had ≥1 provoked VTE; (2) ‘moderate-risk’ pa...

MetabolomicsDiverse metabolic reactions activated during 58-hr fasting are revealed by non-targeted metabolomic analysis of human blood
During human fasting, metabolic markers, including butyrates, carnitines, and branched-chain amino acids, are upregulated for energy substitution through gluconeogenesis and use of stored lipids. We performed non-targeted, accurate semiquantitative metabolomic analysis of human whole blood, plasma, ...

MetabolomicsIntegrating Blood Microsampling Devices with CE-MS for Untargeted Analysis of Polar Metabolomics

Capillary electrophoresis–mass spectrometry (CE-MS) offers considerable advantages for polar compound metabolomics analysis, including simple workflows, fast method development, and suitability for small sample volumes. Blood microsampling (BμS) techniques (such as dried blood spots, quantitative...

TranscriptomicsAcute venous hypertension induces local release of inflammatory cytokines and endothelial activation in humans
Background: Venous hypertension is often present in advanced and in acute decompensated heart failure (HF). However, it is unclear whether high intravenous pressure can cause alterations in homeostasis by promoting inflammation and endothelial cell (EC) activation. We used an experimental model of a...

MetabolomicsUmbilical cord blood metabolome differs in relation to delivery mode, birth order and sex, maternal diet and possibly future allergy development in rural children
Allergy is one of the most common diseases among young children yet all factors that affect development of allergy remain unclear. In a small cohort of 65 children living in the same rural area of south-west Sweden, we have previously found that maternal factors, including prenatal diet, affect chil...
