Project description:Interventions: Case (colorectal cancer) group:a newly diagnosed colorectal cancer( CRC ) by colonoscopy and pathology;Control group:Clinically healthy volunteers with no symptoms or history of intestinal disease(e.g. colonic adenomatous polyps, CRC or inflammatory bowel disease)
Primary outcome(s): composition of gut microbiota;intestinal microbial phytase activity;16s rRNA metagenomic sequencing;diet surveys;phytic acid intake
Study Design: Case-Control study
Project description:Transcriptional profile comparison of the pleural and ascites fluids in hydropic fetuses affected with chylothorax. Two-condition experiment, pleural fluid vs. ascites fluid. Comparison of the transcriptional profile between sample collected before and after OK-432 treatment and between fetuses with and without a G404S mutation in the ITGA9 gene
Project description:We used a metagenomic microarray to detect Human Pegivirus in serum and cerebrospinal fluid from a patient suffering from severe encephalitis.
Project description:<p>Heat stress is an important issue in dairy cattle feeding management affecting summer health and economic efficiency. In recent years, global climate change has led to an increase in atmospheric CO2 content and average daily temperature, making heat stress a major challenge in dairy farming. This experiment combined 16S rDNA sequencing, metagenomic sequencing and metabolomic analysis. In this experiment, 10 cows each of growing heifers, heifers and lactating cows were selected for sample collection in April and August. Ruminal fluid was collected and filtered through gauze, which was immediately transferred to liquid nitrogen prior to macrogenomic, 16S rDNA sequencing and metabolomic analyses.</p>

Project description:In this study we developed metaproteomics based methods for quantifying taxonomic composition of microbiomes (microbial communities). We also compared metaproteomics based quantification to other quantification methods, namely metagenomics and 16S rRNA gene amplicon sequencing. The metagenomic and 16S rRNA data can be found in the European Nucleotide Archive (Study number: PRJEB19901). For the method development and comparison of the methods we analyzed three types of mock communities with all three methods. The communities contain between 28 to 32 species and strains of bacteria, archaea, eukaryotes and bacteriophage. For each community type 4 biological replicate communities were generated. All four replicates were analyzed by 16S rRNA sequencing and metaproteomics. Three replicates of each community type were analyzed with metagenomics. The "C" type communities have same cell/phage particle number for all community members (C1 to C4). The "P" type communities have the same protein content for all community members (P1 to P4). The "U" (UNEVEN) type communities cover a large range of protein amounts and cell numbers (U1 to U4). We also generated proteomic data for four pure cultures to test the specificity of the protein inference method. This data is also included in this submission.
Project description:We profiled scRNA-seq of 284 samples collected from 196 individuals, including 22 patients with mild/moderate symptoms, 54 hospitalized patients with severe symptoms, and 95 recovered convalescent persons, as well as 25 healthy controls. The samples were obtained from various tissue types, including human peripheral blood mononuclear cells (249), bronchoalveolar lavage fluid (12) and pleural pleural effusion (1)/sputum (22).
