Wound healing is a complex dynamic process involving a large number of biological events. Excessive oxidative stress is a key factor delaying wound healing. Hydrogen is an antioxidant, anti-inflammatory, and antiapoptotic medical gas with safety, effectiveness, and penetrability. However, the effects of local treatment of hydrogen on wound healing and its potential mechanisms remain unclear. In this

Molecular hydrogen (H2) is a physiologically inert gas. However, during the last 10 years, increasing evidence has revealed its biological functions under pathological conditions. More specifically, H2 has protec- tive effects against a variety of diseases, particularly nervous system disorders, which include ischemia/reperfu- sion injury, traumatic injury, subarachnoid hemorrhage, neuropathic pain

Molecular hydrogen (H2) is a colorless and odorless gas. Studies have shown that H2 inhalation has the therapeutic effects in many animal studies and clinical trials, and its application is recommended in the novel coronavirus pneumonia treatment guidelines in China recently. H2 has a relatively small molecular mass, which helps it quickly spread and penetrate cell membranes to exert a wide range

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

In recent years, many studies have shown that hydrogen has therapeutic and preventive effects on various diseases. Its selective antioxidant properties were well noticed. Most of the ionizing radiation-induced damage is caused by hydroxyl radicals (.OH) from radiolysis of H2O . Since hydrogen can mitigate such damage through multiple mechanisms, it presents noteworthy potential as a novel radio-pro

H2 has been clinically demonstrated to provide antioxidant and anti-inflammatory effects, which makes it an attractive agent in exercise medicine. Although exercise provides a multiplicity of benefits including decreased risk of disease, it can also have detrimental effects. For example, chronic high-intensity exercise in elite athletes, or sporadic bouts of exercise (i.e. noxious exercise) in unt

Recent studies have revealed unique biological characteristics of molecular hydrogen (H2) as an anti-inflammatory agent. We developed a novel haemodialysis (E-HD) system delivering an H2 (30–80 ppb)-enriched dialysis solution by water electrolysis, and conducted a non-randomized, non-blinded, prospective observational study exploring its clinical impact. Prevalent chronic HD patients were allocate

Hydrogen (H2) is a colorless, odorless gas that can act as a reducing agent under certain circumstances. Previously considered physiologically an inert and nonfunctional molecule in mammalian cells, H2 largely went ignored until Nature Medicine revealed the antioxidant and cytoprotective effects of hydrogen gas in a focal stroke model. Reactive oxygen species (ROS) is generated inside the body thr
