Furthermore, objective testing showed that intestinal permeability (measured by urinary lactulose/mannitol ratios) was completely normalized in the glutamine group, proving its direct barrier-healing capabilities

In eight of ten colonies tested, the introduced URA3 gene could no longer be detected (Figure S3B), and none of the negative clones grew on minimal agar without added uracil
