Read ArticleIn mice, at P14 and P21, no significant difference in the distance from the retinal pigment epithelium to the outer plexiform layer on OCT from mice of the…
Read ArticleIn exploratory analyses, the hydrogen group also showed descriptive trends toward lower pain scores, greater physical independence, and improved sleep quality. These findings add human evidence supporting molecular…
Read ArticleIn rats, the pre-exercise supplement of vitamin C significantly reduced mitochondrial complex IV concentrations and PGC-1α, NRF-1, TFAM gene expression levels compared to the pre-exercise group, but the…
Read ArticleIn 10 healthy participants, compared with the placebo, HRG inhalation significantly improved mean power, fatigue index, and time to peak for the fourth sprint and significantly reduced the…
Read ArticleIn rats, hydrogen possesses antioxidant and anti-apoptotic properties, which could be neuroprotective in the treatment of peripheral nerve injury; however, such a possibility has not been experimentally tested…
Read ArticleIn 8 physically active participants, after exercise HG inhalation attenuated the increase in urinary 8-hydroxydeoxyguanosine excretion rate (P < 0.05), a DNA oxidation marker, and the reduction in…
Read ArticleIn 24 young participants, it was observed that compared to control, after inhaling H₂ gas, participants had significantly lower RPE at each workload phase (p < 0.032) and…
Read ArticleIn conclusion, breathing 4% gaseous hydrogen for 20 min/day for 7 days resulted in increased peak running velocity and attenuated the drop in maximal isometric strength of trunk…
Read ArticleIn 24 healthy participants, compared to a placebo, HRG inhalation induced significant improvement in VAS, RPE, the cycling frequency during the last 30 seconds in the fatigue modeling…
Read ArticleIn 2019 patients, showed that H₂ therapy, compared with placebo, significantly increased 6 MWT distance by 64 ± 39 m, FVC by 0.19 ± 0.24 L, and, in…
Read ArticleThis narrative review examined the available molecular-hydrogen literature. Although H₂ has been thought to be an inert gas in living bodies for many years, an animal study reported…
Read ArticleIn mice, H₂ treatment attenuated serum interleukin-6 and tumor necrosis factor-α levels at 24 h after CLP, and blood glucose levels were maintained in the H₂-treated group. These…
Read ArticleIn mice, 2 Treatment with 2% hydrogen improved the 7-day survival rate and decreased the levels of inflammatory cytokines in septic mouse cortex tissues. These preclinical findings add…
