Low-Flow Nasal Cannula Hydrogen Therapy
Background: Molecular hydrogen (H2) is a biologically active gas that is widely used in the healthcare sector. In recent years, on-site H2 gas generators, which produce high-purity H2 by water electrolysis, have begun to be introduced in hospitals, clinics, beauty salons, and fitness clubs because…
Hydrogen-rich saline protects intestinal epithelial tight junction barrier in rats with intestinal ischemia–reperfusion injury by inhibiting endoplasmic reticulum stress-induced apoptosis pathway
Aim To investigate the effects of hydrogen-rich saline (HRS) on intestinal epithelial tight junction (TJ) barrier in rats with intestinal ischemia–reperfusion injury (IIRI). Materials and methods Thirty-two healthy male Sprague–Dawley (SD) rats were randomly divided into four groups (n = 8 each)…
Molecular Hydrogen Protects Human Melanocytes from Oxidative Stress by Activating Nrf2 Signaling
Oxidative stress is proven to be critical for the initiation and progression of vitiligo. Molecular hydrogen (H2) possesses potent antioxidant activity and has been shown to protect against various oxidative stress-related diseases. In this study, we first investigated the effects and mechanisms…
A new insight into the molecular hydrogen effect on coenzyme Q and mitochondrial function of rats
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…
Hydrogen-induced neuroprotection in neonatal hypoxic-ischemic encephalopathy
Hypoxic-ischemic encephalopathy (HIE) remains to be a major cause of morbidity, mortality and severe neurodevelopmental disability in term neonates. Moderate whole body hypothermia is an established, effective neuroprotective therapy to reduce mortality and long-term disability associated with HIE…
Molecular hydrogen suppresses superoxide generation in the mitochondrial complex I and reduced mitochondrial membrane potential
Molecular hydrogen (H2) is recognized as a medical gas applicable to numerous diseases including neurodegenerative diseases, metabolic disorders, and rheumatoid arthritis. Although the efficacy of H2 is reportedly attributed to its scavenging capability against the hydroxyl radical, the mechanisms…
Hydrogen inhalation alleviates nonalcoholic fatty liver disease in metabolic syndrome rats
Hydrogen exhibits therapeutic and preventive effects against various diseases. The present study investigated the potential protective effect and dose‑dependent manner of hydrogen inhalation on high fat and fructose diet (HFFD)‑induced nonalcoholic fatty liver disease (NAFLD) in Sprague‑Dawley…
Hydrogen-Rich Water Supplementation and Up-Hill Running Performance: Effect of Athlete Performance Level
Purpose: Hydrogen-rich water (HRW) has been shown to have an antifatigue effect. This study assessed up-hill running performance, as well as physiological and perceptual responses after supplementation with 1680 mL HRW between 24 h and 40 min before running, in athletes of heterogeneous running…
Amelioration of Coagulation Disorders and Inflammation by Hydrogen-Rich Solution Reduces Intestinal Ischemia/Reperfusion Injury in Rats through NF-<i>κ</i>B/NLRP3 Pathway
Intestinal ischemia/reperfusion (I/R) injury often causes inflammatory responses and coagulation disorders, which is further promoting the deterioration of the disease. Hydrogen has anti-inflammatory, antioxidative, and antiapoptotic properties against various diseases. However, the effect…
Hydrogen-rich water reduces inflammatory responses and prevents apoptosis of peripheral blood cells in healthy adults: a randomized, double-blind, controlled trial
The evidence for the beneficial effects of drinking hydrogen-water (HW) is rare. We aimed to investigate the effects of HW consumption on oxidative stress and immune functions in healthy adults using systemic approaches of biochemical, cellular, and molecular nutrition. In a randomized…
Molecular hydrogen downregulates acute exhaustive exercise-induced skeletal muscle damage
Physical exercise-induced skeletal muscle damage may be characterized by increased oxidative stress, inflammation, and apoptosis which may be beneficial when exercise is regular, but it is rather harmful when exercise is exhaustive and performed acutely by unaccustomed individuals. Molecular…
Hydrogen inhalation inhibits microglia activation and neuroinflammation in a rat model of traumatic brain injury
Traumatic brain injury (TBI) is a major cause of mortality and disability worldwide. To date, therapies to treat any forms of TBI are still limited. Recent studies have demonstrated the potential neuroprotective effects of molecular hydrogen on TBI. Although it has been demonstrated that hydrogen…
Luminal preloading with hydrogen-rich saline ameliorates ischemia-reperfusion injury following intestinal transplantation in rats
Prolonged intestinal cold storage causes considerable mucosal breakdown, which could bolster bacterial translocation and cause life-threatening infection for the transplant recipient. The intestine has an intraluminal compartment, which could be a target for intervention, but has not yet been fully…
Synergistic Effects of Regular Walking and Alkaline Electrolyzed Water on Decreasing Inflammation and Oxidative Stress, and Increasing Quality of Life in Individuals with Type 2 Diabetes: A Community Based Randomized Controlled Trial
Alkaline electrolyzed water (AEW) and walking are strongly recommended for ameliorating oxidative stress and inflammation. Nevertheless, there is a lack of information on the combination of both on alleviating inflammation, oxidative stress, and improving the quality of life (QoL). We investigated…
Changes of nasal nitric oxide in the treatment of allergic rhinitis with hydrogen-rich saline lavage of nasal cavity
Objective:To observe the effect of hydrogen-rich saline on the concentration of nitric oxide in the nose, and to explore the mechanism of its treatment of allergic rhinitis. Method:Twenty patients with moderate to severe persistent allergic rhinitis were enrolled in a randomized, double-blind…
Hydrogen-rich water alleviates cyclosporine A-induced nephrotoxicity via the Keap1/Nrf2 signaling pathway
Oxidative stress induced by long-term cyclosporine A (CsA) administration is a major cause of chronic nephrotoxicity, which is characterized by tubular atrophy, tubular cell apoptosis, and interstitial fibrosis in the progression of organ transplantation. Although hydrogen-rich water (HRW) has been…
Hydrogen inhibits the osteoclastogenesis of mouse bone marrow mononuclear cells
Hydrogen (H2) is one of the major biodegradation products of magnesium (Mg) alloys implanted for bony fracture healing and reconstruction; H2 thus plays a significant role in the regulation of local microenvironment and the biology of resident cells. The interactions between the H2 and the local…
Pharmacokinetics of a single inhalation of hydrogen gas in pigs
The benefits of inhaling hydrogen gas (H2) have been widely reported but its pharmacokinetics have not yet been sufficiently analyzed. We developed a new experimental system in pigs to closely evaluate the process by which H2 is absorbed in the lungs, enters the bloodstream, and is distributed…
