l-Theanine Alleviates Ulcerative Colitis by Regulating Colon Immunity via the Gut Microbiota in an MHC-II-Dependent Manner.

Alterations to the gut microbiota are associated with ulcerative colitis (UC), whereas restoration of normobiosis can effectively alleviate UC. l-Theanine has been shown to reshape the gut microbiota and regulate gut immunity. To investigate the mechanisms by which l-theanine alleviates UC, we used l-theanine and l-theanine fecal microbiota solution to treat UC mice.

Role of spatial coherence in Goos-Hänchen and Imbert-Fedorov shifts: comment.

It is shown that the spatial Goos-Hänchen shift is greatly affected by spatial coherence. A typical example is given.
