Recent data suggest that ellagitannins (ETs), a class of hydrolyzable tannins found in some fruits and nuts, may have beneficial effects against colon cancer. In the stomach gut, ETs hydrolyze to release ellagic acid (EA) are converted by gut microbiota urolithin A (UA; 3,8-dihydroxy-6H-dibenzopyran-6-one) type metabolites, which persist through enterohepatic circulation. However, little is known about mechanisms action either native compounds or their metabolites on carcinogenesis....

Emerging data suggest that urolithins, gut microbiota metabolites of ellagitannins, contribute toward multiple health benefits attributed to ellagitannin-rich foods, including walnuts, red raspberry, strawberry, and pomegranate. However, there is limited on whether the potential neuroprotective effects these foods are mediated by urolithins. Herein, we evaluated mechanisms antineuroinflammatory urolithins (urolithins A, B, C; 8-methyl-O-urolithin A; 8,9-dimethyl-O-urolithin C) in BV2 murine...

Chronic neuroinflammation serves a key role in the onset and progression of neurodegenerative disorders. Mitochondria serve as central regulators neuroinflammation. In addition to providing energy cells, mitochondria also participate immunoinflammatory response disorders including Alzheimer's disease, Parkinson's multiple sclerosis epilepsy, by regulating processes such cell death inflammasome activation. Under inflammatory conditions, mitochondrial oxidative stress, epigenetics, dynamics...

Plants of the Carex genus (Family: Cyperaceae) have attracted recent attention as potential food additives because they contain high levels bioactive polyphenols commonly found in plant foods. Seven compounds, which included two resveratrol oligomers and five flavonoids, were isolated from seeds folliculata L. (northern long sedge), a forage prevalent northern United States. The compounds identified by 1H 13C nuclear magnetic resonance mass spectrometry data. pallidol (1), dimer reported to...
