This narrative review examined the available molecular-hydrogen literature. The biological effects of molecular hydrogen are moving beyond the traditional explanatory framework of "selective antioxidation." This article systematically integrates the basic, preclinical, and preliminary clinical evidence for hydrogen in metabolic diseases, neurodegenerative disorders,…
Read ArticleThis narrative review examined the available molecular-hydrogen literature. The reviewed evidence adds support for molecular hydrogen's therapeutic potential across the conditions, mechanisms, or outcomes examined.
Read ArticleThe researchers observed that anxiety/depression-like behaviors in experimental autoimmune encephalomyelitis (EAE) mice were alleviated by MgH2 treatment. These preclinical findings add evidence supporting molecular hydrogen's therapeutic potential within…
Read ArticleIn a laboratory model, hydrogen administration also promoted mitochondrial biogenesis and significantly decreased lactate production. The authors concluded that preconditioning lung grafts using inhaled hydrogen attenuated these proinflammatory…
Read ArticleIn SH-SY5Y cells, H₂ treatment significantly improved cell viability, attenuated oxidative stress and mitochondrial dysfunction, and enhanced mitophagy via activation of the PINK1/Parkin pathway. The authors linked these…
Read ArticleIn mice, intermittent hypoxia significantly increased plasma levels of low- and very low-density cholesterol and the amount of 4-hydroxy-2-nonenal-modified protein adducts in the LV myocardium. These preclinical findings…
Read ArticleIn the hippocampus, H₂ upregulated nuclear factor erythroid 2-related factor 2 (NRF2), attenuated nuclear factor kappa B (NF-κB) activation, reduced the BAX/BCL-2 ratio, preserved neuronal nuclei (NEUN) expression,…
Read ArticleH2HUBB PLAIN-LANGUAGE TAKEAWAY The study adds to the molecular-hydrogen evidence base, but the available record does not support a firm conclusion about therapeutic benefit. Hydrogen-rich saline mitochondrial function…
Read ArticleIn mice, spinal cord neurons were preserved by hydrogen administration after mechanical injury in a dose-dependent manner. These results are preclinical and suggest molecular hydrogen's therapeutic potential in…
Read ArticleIn mice, the present study showed that hydrogen gas therapy increased the 7-day survival rate, improved cognitive function, increased the mitochondrial function (MMP, ATP level, complex I activity)…
Read ArticleH2HUBB PLAIN-LANGUAGE TAKEAWAY The study adds to the molecular-hydrogen evidence base, but the available record does not support a firm conclusion about therapeutic benefit. Molecular hydrogen mitochondrial function…
Read ArticleThis narrative review examined the available molecular-hydrogen literature. Although it is widely known that molecular hydrogen can react with hydroxyl radicals, generated in the mitochondria, to protect cells…
Read ArticleH2HUBB PLAIN-LANGUAGE TAKEAWAY The study adds to the molecular-hydrogen evidence base, but the available record does not support a firm conclusion about therapeutic benefit. Hydrogen water research study…
Read ArticleThis narrative review examined the biological rationale and early clinical evidence for oxy-hydrogen inhalation in respiratory conditions. The authors highlighted early evidence of cytoprotective, antioxidant, and anti-inflammatory effects.…
Read ArticleIn rats, molecular hydrogen can easily attach to biomembranes and enter cytosol, mitochondria and other organelles of the cell and convert the formed OH- to H₂O to prevent…
