Study at a glance
Preclinical
mice, tissues, tissue used to study other neurological conditions.
Full text reports inhaled H₂-containing gas. Detected intervention quantities or schedules: 4%, 42%, 67%. · H₂-related quantities reported in the intervention passages: 4%, 42%, 67%. Values are not combined across different experimental arms.
Multiple article-specific time points; see the linked full methods.
Article-reported result excerpt (24 words maximum): “It could be seen that the H_2 concentrations in five tissues of mice increased significantly over time during the H_2 inhalation of any concentration.” This excerpt is not a complete result summary; consult the linked full text for all positive and null findings.
Preclinical evidence only; findings do not establish a treatment effect in people. Funding or grant information is reported in the full article. The article declares no conflicts of interest.
What kind of evidence is this?
Preclinical
Controlled preclinical study
Other neurological conditions
Inhaled H₂
Information not yet classified
Some editorial classification fields are still pending. The source-reported outcomes and result are shown below; Hydrogenology does not infer a positive or negative signal from prose automatically.
Methods
mice, tissues, tissue used to study other neurological conditions.
Preclinical study; group or assay counts reported in the full text include n=3.
Multiple article-specific time points; see the linked full methods.
Full text reports inhaled H₂-containing gas. Detected intervention quantities or schedules: 4%, 42%, 67%.
Inhaled molecular H₂ at 4%; not classified as Brown’s gas without an H₂/O₂ composition.
H₂-related quantities reported in the intervention passages: 4%, 42%, 67%. Values are not combined across different experimental arms.
Not reported in the full article — an absolute H₂ flow in mL/min could not be verified.
O₂ concentration and absolute O₂ flow were not both reported in the full article; no value is inferred.
Control or comparison condition reported in the full article; see the linked methods for arm-specific details.
Outcomes and reported result
inflammation and cytokines, apoptosis or cell injury, histology or tissue damage, respiratory measures, microbiome composition
Article-reported result excerpt (24 words maximum): “It could be seen that the H_2 concentrations in five tissues of mice increased significantly over time during the H_2 inhalation of any concentration.” This excerpt is not a complete result summary; consult the linked full text for all positive and null findings.
The complete machine-readable article was checked for source identity, methods, intervention quantities, results, tables, funding and conflict declarations. This public record is based on the full article.
A reported association, difference or mechanism is not automatically a clinical benefit.
Limitations and applicability
Preclinical evidence only; findings do not establish a treatment effect in people. Funding or grant information is reported in the full article. The article declares no conflicts of interest.
Applies to the reported animal, cell or tissue model, not directly to patients.
No single-study GRADE certainty rating is assigned. Read how records and evidence assessments are prepared.
