Project description:To explore metabolic changes associated with CSDS-induced gut microbiota modulation, we performed untargeted metabolomic profiling of colonic and jejunal contents using UPLC-MS/MS in both positive and negative ion modes.
Project description:<p>This study investigated the effects of dietary 0.10% chlorogenic acid supplementation on the meat quality and metabolic profile of Shaziling pigs. Longissimus dorsi muscle samples were collected and analyzed using untargeted liquid chromatography-mass spectrometry (LC-MS) in both positive and negative ion modes. The dataset includes raw LC-MS data and metabolite annotation information to characterize metabolic changes associated with chlorogenic acid supplementation and meat quality traits in Shaziling pigs.</p>
Project description:The data set contains MS/MS data on teeth extracts for Ancient DNA teeth samples ran in both positive and Negative ionization modes
Project description:This study investigates the metabolic responses of two Zoysia species (Z. macrostachya and Z. sinica) adapted to distinct microhabitats in the Yellow River Delta. Leaf samples were collected from natural populations growing under different saline-alkaline conditions. Untargeted metabolomics was performed using LC-MS in both positive and negative ion modes to profile the metabolite composition. The results revealed significant differences in key metabolic pathways, including tryptophan metabolism, flavonoid biosynthesis, and phenylpropanoid metabolism, between the two species, providing insights into their differential adaptation to saline-alkaline stress.
Project description:Seeds of Arabidopsis thaliana wild type and knockout-mutants for flavonoid genes (tt7 [3 lines], fls1, tt3, tt4, tt7tt4 [2 lines] ) were subjected to untargeted metabolomic analyses (LC-MS/MS) in positive and negative ionisation mode.
Project description:Secondary metabolite profiles of Aspergillus fumigatus aneuploids, WT, and nscROE strains under FK506 stress. Data include both positive and negative ionization modes from a 25-minute reverse-phase run conducted in 2025.
Project description:This study investigated the effects of Xijiao Dihuang Decoction (XDD) on cerebral ischemia–reperfusion injury using a middle cerebral artery occlusion/reperfusion rat model. Untargeted LC–MS metabolomics was performed on fecal samples to characterize metabolic alterations associated with MCAO/R and XDD treatment. Metabolomic profiles were acquired in both positive- and negative-ion modes and integrated with gut microbiome data to explore microbiota–metabolite associations.
