MHID-6285582PMID: 346451002021Journal of Integrative Neuroscience

Tyler W. LeBaron, Jason Kharman, Michael L. McCullough

Traumatic brain injuries (TBIs) are a leading cause of death and dis- ability. Sports-related TBIs are estimated to be more than several million per year. The pathophysiology of TBIs involves high levels of inflammation, oxidative stress, dysregulation of ion homeosta- sis, mitochondrial dysfunction, and apoptosis. There is also a reduc- tion in cerebral blood flow, leading to hypoxia and reduced

COVID-19 is a widespread global pandemic with nearly 185 million confirmed cases and about four million deaths. It is caused by an infection with the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), which primarily affects the alveolar type II pneumocytes. The infection induces pathological responses including increased inflammation, oxidative stress, and apoptosis. This situation result

Takuji Kawamura, Kazuhiko Higashida, Isao Muraoka

Molecular hydrogen (H2) is a colorless, tasteless, odorless, and minimal molecule with high flammability. Although H2 has been thought to be an inert gas in living bodies for many years, an animal study reported that inhalation of H2 gas decreased oxidative stress and suppressed brain injury caused by ischemia and reperfusion injury due to its antioxidant action. Since then, the antioxidant action
