MetabolomicsMethod Comparison using DBS samples

Metabolomics serves as a critical pillar in clinical research, yet the lack of standardized protocols often limits the comparability of data across different platforms and institutions. The HUMAN (Harmonizing and Unifying Blood Metabolomics Network) has as one of its goals to to advance the field...

MetabolomicsMarine metabolomics: measurement of metabolites in seawater by gas chromatography mass spectrometry (Method development)
One of the major bottlenecks in describing marine ecosystems is characterizing the metabolome of seawater, as salt prevents metabolite analysis. We present SeaMet, a method that can detect hundreds of metabolites in less than one ml of seawater and quantifies them down to nano-molar levels using gas...

MetabolomicsMultiomic Approach to Analyze Infant Gut Microbiota: Experimental and Analytical Method Optimization

BACKGROUND: The human intestinal microbiome plays a central role in overall health status, especially in early life stages. 16S rRNA amplicon sequencing is used to profile its taxonomic composition; however, multiomic approaches have been proposed as the most accurate methods for...

MetabolomicsA Comprehensive and Ultrasensitive Isotope Calibration Method for Soil Amino Compounds Using Orbitrap Mass Spectrometry
Bound amino compounds (amino acid and amino sugar polymers) comprise a significant proportion (~40%) of soil organic nitrogen and therefore represent an essential source of nitrogen for plant and microbial nutrition. The analysis of their content and isotope enrichment still represents a significant...

MetabolomicsUntargeted In Silico Compound Classification - A Novel Metabolomics Method to Assess the Chemodiversity in Bryophytes

In plant ecology, biochemical analyses of bryophytes and vascular plants are often conducted on dried herbarium specimen as species typically grow in distant and inaccessible locations. Here, we present an automated in silico compound classification framework to annotate metabolites using an unta...

MetabolomicsA robust method for performing 1H-NMR lipidomics in embryonic zebrafish
The embryonic zebrafish is an ideal system for lipid analyses with relevance to many areas of bioscience research, including biomarkers and therapeutics. Research in this area has been hampered by difficulties in extracting, identifying and quantifying lipids. We employed 1H-NMR at 700MHz to profile...

MetabolomicsDetermination and comparison of SCFAs in serum and colon content samples: Alzheimer's disease rat as a case study (Method validation)

SCFAs are the main microbial fermentation products from dietary fibers in colon and play a key role in keeping healthy in the whole-body. However, differences of SCFAs concentration in the serum and colon samples collected from rats had attracted few attentions. Here, we optimized the extract and...

MetabolomicsA new method for quantitative determination of bitter components of Belgian endive, with a focus on sesquiterpene oxalates
The sesquiterpene lactones typical of the genera Cichorium and Lactuca were historically thought to be present in the free and glycosylated form, but recent developments have highlighted the presence of highly unusual oxalyl esters. In this work, first a liquid chromatography method that requires mi...

MetabolomicsAn ancient residue metabolomics-based method to distinguish use of closely related plant species in ancient pipes

Residues from ancient artifacts can help identify which plant species were used for their psychoactive properties, providing important information regarding the deep-time co-evolutionary relationship between plants and humans. However, relying on the presence or absence of one or several biomarke...
