Gut microbiota plays a crucial role in inflammatory bowel diseases (IBD) and can potentially prevent IBD through microbial-derived metabolites, making it a promising therapeutic avenue. Recent evidence suggests that despite an unclear underlying mechanism, red cabbage juice (RCJ) alleviates Dextran Sodium Sulfate (DSS)-induced colitis in mice. Thus, the study aims to unravel the molecular mechanism by which RCJ modulates the gut microbiota to alleviate DSS-induced colitis in mice. Using C57BL/6J mice, we evaluated RCJ’s protective role in DSS-induced colitis through two cycles of 3% DSS. Mice were daily gavaged with PBS or RCJ until the endpoint, and gut microbiota composition …

The Complexities Of Green Infrastructure, Troy Weber
Purdue Journal of Service-Learning and International Engagement
The Wabash River is the most extensive river system in Indiana. The river drains two-thirds of Indiana’s 92 counties, which can have issues associated with stormwater runoff (Weist, 1981). As precipitation runs off impervious surfaces, it can carry high concentrations of pollutants, such as excess nitrogen and phosphorus, pet waste, and automobile fuel. Prior to impervious runoff entering the river, preexisting contaminants include industrial waste (acid mine drainage and oil field brines), municipal waste, and sediment (Weist, 1981). Thus, stormwater runoff can negatively impact the Wabash River watershed. On top of this pollution, Lafayette and West Lafayette have combined sewer …
