Hydrogen alleviates myocardial infarction by impeding apoptosis via ROS-mediated mitochondrial endogenous pathway.

In Sprague-Dawley rats, mitochondrial ATP content, mitochondrial complex I, and mitochondrial complex III activity were significantly decreased in the MI group, which was improved after hydrogen administration. These preclinical findings add evidence supporting molecular hydrogen's therapeutic potential within the outcomes and biological pathways measured in this model.

Molecular hydrogen: potential in mitigating oxidative-stress-induced radiation injury 1.

This narrative review examined the available molecular-hydrogen literature. Irradiation of the rats caused a significant increase in lipid peroxidation, which was mitigated by pre-treatment of the animals with molecular hydrogen. The reviewed evidence adds support for molecular hydrogen's therapeutic potential across the conditions, mechanisms, or outcomes examined.

Chronic hydrogen-rich saline treatment attenuates vascular dysfunction in spontaneous hypertensive rats.

In rats, treatment with HRS had no significant effect on blood pressure, but it significantly improved baroreflex function in SHR. Although treatment with HRS had no significant effect on nitric oxide amount in circulating or aorta, it suppressed endothelial nitric oxide synthase expression and upregulated dimethylarginine dimethylaminohydrolase 2 expression in SHR. These preclinical findings add evidence supporting molecular hydrogen's therapeutic potential within the outcomes and biological pathways measured in this model.

Hydrogen Gas in Cancer Treatment.

This narrative review examined the available molecular-hydrogen literature. Growing evidence has shown that hydrogen gas can either alleviate the side effects caused by conventional chemotherapeutics, or suppress the growth of cancer cells and xenograft tumor, suggesting its broad potent application in clinical therapy. The reviewed evidence adds support for molecular hydrogen's therapeutic potential across the conditions, mechanisms, or outcomes examined.

Engineering a Tumor‐Targeted MgH 2 @Lip/PD‐L1 Nanoplatform for Synergistic Hydrogen Therapy and Immune Activation

In vivo, it achieves efficient tumor homing, suppresses tumor growth in both immunodeficient and immunocompetent models, and reprograms the TME by lowering Tregs and M2 macrophages while enhancing M1 polarization and CD3 + /CD45 + T cell infiltration. This source-grounded publication contributes evidence relevant to molecular hydrogen and is retained in a transparent general research category when a more specific study design is not supported by the indexed record.

Hydrogen gas improves photothermal therapy of tumor and restrains the relapse of distant dormant tumor.

In a laboratory model, ammonia borane was linked to the surface of polydopamine through the interaction of hydrogen bonding, which could destroy redox homoeostasis in tumor cells and reduce inflammation by H₂ release in tumor microenvironment. These findings from a laboratory model add evidence supporting molecular hydrogen's biological and therapeutic potential in the model studied.

Hydrogen-water enhances 5-fluorouracil-induced inhibition of colon cancer.

In This study aimed to investigate the role of H₂ incombination with 5-fluorouracil (5-FU) in cancer treatment both in vitro and in vivo using the colon 26 cell line, hydrogen water administration improved the survival of mice with colon 26-induced cancer. The authors concluded that, high-content hydrogen water can inhibit colon cancer, particularly in combination with 5-fluorouracil. These findings from a laboratory model add evidence supporting molecular hydrogen's biological and therapeutic potential in the model studied.
