    Physiologic values. by Hiroki Iwata (2434012)

    Published 2023
    “…The serum syndecan-1 concentration, a glycocalyx component, in the 4% hydrogen group (5.7 ± 4.4 pg/mL) was lower than in the control (19.5 ± 6.6 pg/mL) and 2% hydrogen (19.8 ± 5.0 pg/mL) groups (<i>P</i> < 0.001 for each), but it was not significantly different from the sham group (6.2 ± 4.0 pg/mL, <i>P</i> = 0.999). …”
