PRObing The Efficacy of Commercial Stage Storage Buffers and Evaluating Gut Metaproteome Variability Between Individuals

The study aims to assess the effectiveness of various commercial and non-hazardous buffers for the storage of human gut fecal samples over time. This evaluation will be conducted by comparing the performance of these buffers against directly frozen samples using metaproteomic analysis. The study is motivated by the need for standardized protocols for sample preservation in metaproteomic research, particularly focusing on protein preservation in fecal samples. By investigating proteomic, taxonomic, and functional identifications, the research seeks to provide insights into the reliability of these buffers as storage solutions. Additionally, the study plans to explore inter- and intra-individual variabilities at the proteome level by periodically collecting fecal samples from volunteers, complementing existing knowledge in metaproteomics. Overall, the study addresses a critical gap in the field and has the potential to enhance reproducibility and comparability across metaproteomic studies

Dietary Counseling Coupled With FMT in the Treatment of Obesity and NAFLD - the DIFTOB Study

There are several studies performed to reveal the linkage between diet, fecal microbiota, and obesity. Human fecal microbiota transplantations in this asset are still scarce. Therefore, this pilot study of FMT from lean to obese people with dietary counseling will increase the knowledge, whether FMT could play a role in the treatment of obesity and NAFLD. Our primary outcome is the changes in glucose metabolism by HOMA-IR.
