MetabolomicsHigh-Precision Automated Workflow for Urinary Untargeted Metabolomic Epidemiology
Urine is a non-invasive biofluid that is rich in polar metabolites and well-suited for metabolomic epidemiology. However, due to individual variability in health and hydration status, the physiological concentration of urine can differ >15-fold, which can pose major challenges in untargeted LC-MS me...

MetabolomicsGNPS - Lipidomics of homeoviscous adaptation to low temperatures in Staphylococcus aureus utilizing exogenous straight-chain unsaturated fatty acids over biosynthesized endogenous branched-chain fatty acids
It is well established that Staphylococcus aureus can incorporate exogenous straight-chain unsaturated fatty acids (SCUFAs) into membrane phospho- and glyco-lipids from various sources in supplemented culture media, and when growing in vivo in an infection. Given the enhancement of membrane fluidity...

MetabolomicsMetabolic phenotyping of urine from a dementia research cohort
To better understand the molecular mechanisms underpinning physiological variation in human populations, metabolic phenotyping approaches are increasingly being applied to studies involving hundreds and thousands of biofluid samples. Hyphenated ultra-performance liquid chromatography-mass spectromet...

MetabolomicsGNPS Revealing fatty acid heterogeneity in Staphylococcal lipids with isotope labeling and RPLC-IM-MS
Up to 80% of the fatty acids in Staphylococcus aureus membrane lipids are branched, rather than straight-chain, fatty acids. The branched fatty acids (BCFAs) may have either an even or odd number of carbons and the branch position may be at the penultimate carbon (iso) or the antepenultimate (anteis...

MetabolomicsFecal microbiota transplantation plus anti-PD-1 immunotherapy in advanced melanoma: a phase I trial

Fecal microbiota transplantation (FMT) represents a potential strategy to overcome resistance to immune checkpoint inhibitors in patients with refractory melanoma; however, the role of FMT in first-line treatment settings has not been evaluated. We conducted a multicenter phase I trial combining ...

MetabolomicsMetabolism links nutrient stress and harmful algal bloom formation

Four species of phytoplankton representing important bloom-forming species from three globally important phyla (Bacillariophyta, Haptophyta, and Ochrophyte) were cultured in this study. These species include the cosmopolitan diatom Chaetoceros affinis CCMP159 (isolated from Great South B...

MetabolomicsDissolved metabolites from the Bermuda Atlantic Time-series Study: 2016-2019

Organic carbon in seawater plays a significant role in the global carbon cycle. The concentration and composition of dissolved organic carbon, operationally defined in this project as organic carbon that passes through a 0.2 µm filter, reflect the actions of the biological community and chemical ...

MetabolomicsMigratory Zooplankton Excreta and its Influence on Prokaryotic Communities

Particulate organic matter (fecal pellets) from zooplankton has been demonstrated to be important nutrient sources for the pelagic prokaryotic community. Significantly less is known about the chemical composition of the dissolved organic matter (DOM) produced by these eukaryotes and its infl...
