Molecular hydrogen has been suggested to have a cytoprotective effect on the whole body and to enhance exercise performances. However, the effect of hydrogen-rich gas mixture (HG) inhalation on physiological responses has been poorly investigated. We examined the impact of acute HG inhalation on subsequent oxidative stress, muscle damage, and exercise performances during the recovery period after

A recent clinical study demonstrated that haemodialysis with a dialysate containing hydrogen (H2) improves blood pressure control in end-stage kidney disease. Herein, we examined whether H2 has a salutary effect on hypertension in animal models. We subjected 5/6 nephrectomised rats to inhalation of either H2 (1.3% H2 + 21% O2 + 77.7% N2) or control (21% O2 + 79% N2) gas mixture for 1 h per day. H2

Molecular hydrogen (H2) exhibits a wide breadth of botanical effects especially in improving the resistance to abiotic stress. However, the primary target is not clear. Bidirectional hydrogenases have been well studied in microbes and alga, but there is a paucity of research in higher plants. Here, we used real-time spectrophotometry, gas chromatography and H2 sensor to detect the H2-evolving and

Mitochondria are the major source of cellular energy metabolism. In the cardiac cells, mitochondria produce by way of the oxidative phosphorylation more than 90% of the energy supply in the form of ATP, which is utilized in many ATP-dependent processes, like cycling of the contractile proteins or maintaining ion gradients. Reactive oxygen species (ROS) are by-products of cellular metabolism and th

Hydrogen medicine has traveled a long and bumpy road. From the very first study published in 1975 in Science to a seminal paper from 2007 from Nature Medicine and many succeeding reports, molecular hydrogen (H2) has been affirmed as a beneficial agent in various pathologies yet still remains outside of conventional healthcare practice. A highly promising therapeutic, hydrogen appears to currently

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
