In VitroIn SilicoHighlightedQuantification of hydrogen production by intestinal bacteria that are specifically dysregulated in Parkinson’s diseaseMHID-67149392018PLoS ONEAnzu Suzuki, Mikako Ito, Tomonori Hamaguchi, Hiroshi Mori, Yuka Takeda, Ryuko Baba, et al.Oral administration of hydrogen water ameliorates Parkinson’s disease (PD) in rats, mice, and humans. We previously reported that the number of putative hydrogen-producing bacte- ria in intestinal microbiota is low in PD compared to controls. We also reported that the amount of hydrogen produced by ingestion of lactulose is low in PD patients. The decreased hydrogen production by intestinal microb
