double wiper seal

An oil seal, also known as a lip seal or rotary seal, is a device used to seal the junction between stationary and moving parts in machinery. Its primary function is to prevent the leakage of lubricants, such as oil or grease, while simultaneously barring dirt and contaminants from entering the system. This is crucial for maintaining the efficiency and longevity of mechanical components.

From dyes to flavorings, many people are becoming increasingly aware of the ingredients in their food.

Australian researchers examined how titanium dioxide as a food additive affected gut microbiota in mice by orally administering it in drinking water. The study, published in the journal Frontiers in Nutrition in 2019, found the treatment could “alter the release of bacterial metabolites in vivo and affect the spatial distribution of commensal bacteria in vitro by promoting biofilm formation. We also found reduced expression of the colonic mucin 2 gene, a key component of the intestinal mucus layer, and increased expression of the beta defensin gene, indicating that titanium dioxide significantly impacts gut homeostasis.” The changes were then linked to colonic inflammation, along with a higher expression of inflammatory cytokines, which are signal proteins that help with regulation. The researchers concluded that titanium dioxide “impairs gut homeostasis which may in turn prime the host for disease development.”
