We include the result of the PR:PROJECT_SUMMARY global alterations that occur in the intestinal microbiota in a cohort of AF PR:PROJECT_SUMMARY patients and matched controls based on a strategy of metabolomic analyses. Our PR:PROJECT_SUMMARY findings characterize the disordered microbial metabolite profiles in AF.

CO:SAMPLE_TYPE Feces #TREATMENT TR:TREATMENT_SUMMARY To explore how the host metabolic pattern alterations were impacted by the gut TR:TREATMENT_SUMMARY microbiota dysbiosis in AF patients, serum samples were collected and analyzed TR:TREATMENT_SUMMARY by high-throughput liquid chromatography-mass spectrometry (LC/MS). #SAMPLEPREP SP:SAMPLEPREP_SUMMARY 50 mg fecal samples were pipetted into centrifuge tubes (1.5 mL) in preparation SP:SAMPLEPREP_SUMMARY for extraction. The protein was precipitated with 800 μL of methanol and 10 μL SP:SAMPLEPREP_SUMMARY of internal standard (2.9 mg/mL, DL-o-Chlorophenylalanine) was added. The SP:SAMPLEPREP_SUMMARY samples were ground at 65 KHz for 90 s and centrifuged at 12000 rpm for 15 min SP:SAMPLEPREP_SUMMARY at 4 °C. 200 μL of the supernatant was transferred into a vial for further SP:SAMPLEPREP_SUMMARY analysis. #CHROMATOGRAPHY CH:CHROMATOGRAPHY_TYPE Reversed phase MS:INSTRUMENT_NAME Thermo Orbitrap Elite Hybrid Ion Trap-Orbitrap CH:COLUMN_NAME Thermo Hypergod C18 (100 × 4.6 mm 3 µm) #ANALYSIS AN:ANALYSIS_TYPE MS #MS MS:INSTRUMENT_NAME Thermo Orbitrap Elite Hybrid Ion Trap-Orbitrap MS:INSTRUMENT_TYPE Orbitrap MS:MS_TYPE ESI MS:ION_MODE POSITIVE MS:MS_COMMENTS All metabolomic data were prepared for feature extraction and preprocessed with MS:MS_COMMENTS Compound Discoverer 2.0 software (Thermo). Using SIMCA-P software (Umetrics AB, MS:MS_COMMENTS Umea, Sweden), a multivariate Analysis (MVA) was performed. The exact molecular MS:MS_COMMENTS mass, ppm and ms/ms value of these compounds was used to identify the MS:MS_COMMENTS metabolites related to the featured peak in the Metlin database MS:MS_COMMENTS (http://metlin.scripps.edu). The score value indicated the matching rate was MS:MS_COMMENTS calculated by Compound Discoverer 2.0 software (Thermo) with max of 100.
