MetabolomicsUntargeted Metabolomics for Integrative Taxonomy: Metabolomics, DNA Marker-Based Sequencing, and Phenotype Bioimaging

Integrative taxonomy is a fundamental part of biodiversity and combines traditional morphology with additional methods such as DNA sequencing or biochemistry. Here, we aim to establish untargeted metabolomics for use in chemotaxonomy. We used three thallose liverwort species Riccia glauca

MetabolomicsCharacterization of active peptides derived from three leeches and comparison of their anti-thrombotic mechanisms using the tail vein thrombosis model in mice and metabonomics

BACKGROUND AND AIMS: The increasing incidence of cardiovascular diseases has created an urgent need for safe and effective anti-thrombotic agents. Leech, as a traditional Chinese medicine, has the effect of promoting blood circulation and removing blood stasis, but its real mater...

ProteomicsIdentification of collagen marker peptides for animal source identification of crocodilian leather
For species discrimination of crocodilian leather, we performed LC-MS/MS identification of type I collagen-derived marker peptides using leathers made from crocodile, alligator, caiman, and lizard skins.

ProteomicsIdentification of universally applicable and species-specific marker peptides for Bacillus anthracis
Anthrax is a zoonotic infection caused by the bacterium Bacillus anthracis (BA), a gram-positive, aerobic, spore-forming bacterium that can be misused as a biowarfare agent. The major patho-genicity factors of BA are encoded by genes located on two extrachromosomal plasmids, which are often targeted...

ProteomicsDiscovery, Verification, and Validation of Walnut Protein Marker Peptides Using LC-MS/MS Approaches
A key requirement of liquid chromatography-mass spectrometry (LC-MS)-based allergenic food protein analysis methods is to use protein marker peptides with good analytical performances in LC-MS analysis of commercial processed foods. In this study, we developed a multistage walnut protein marker pept...

ProteomicsIdentificatrion of marker peptides for the oilseed species chia, coconut, flaxseed, hemp, pumpkin, rapeseed, sesame, and sunflower
Food fraud is a common issue in the modern food industry. The undeclared use of foreign pro-teins in meat products is a major concern in this context. Oilseeds are ideal for this purpose due to their high protein content and since huge amounts of oil meals are obtained as a by-product of oil product...
