Hydroxyl radicals play an important role in ionizing radiation-induced cellular damage, while hydrogen can selectively reduce hydroxyl radicals in vitro. This study was designed to test the hypothesis that hydrogen-rich PBS may be an effective radioprotective agent in vitro. Com pared to cells pretreated with out hydrogen, we demonstrated that treating cells with hydrogen-rich PBS be fore irradiat

Hydrogen is the most abundant chemical element in the universe, however, it is seldom regarded as a therapeutic gas. Recent studies show that inhaled hydrogen gas (H2) has antioxidant and antiapoptotic activities that protect the brain against ischemia–reperfusion injury and stroke by selectively reducing hydroxyl and peroxynitrite radicals. It is also well known that more than a half of the ioniz

It has been demonstrated that hydrogen can selectively reduce hydroxyl and peroxynitrite in vitro. Since most of the ionizing radiation-induced cellular damage is caused by hydroxyl radicals, this study was designed to test the hypoth- esis that hydrogen may be an effective radioprotective agent. This paper demonstrates that treating cells with hydrogen before irradiation could signifi cantly inhib

Most ionizing radiation-induced damage is caused by radical oxygen species (ROS).
Some
radioprotectors, such as amifostine, exert radioprotective effects by scavenging radical oxygen species.

Most ionizing radiation-induced damage is caused by hydroxyl radicals, and the selective reduction
of hydroxyl by hydrogen in vitro has been demonstrated previously. Irradiation of the heart can cause
chronic cardiac disease. This study was designed to test the hypothesis that hydrogen-rich water (pure
water saturated with molecular hydrogen), which is easy to use, induces cardioprotection against

Metabolic syndrome is characterized by cardiometabolic risk factors that include obesity, insulin resistance, hypertension and dyslipidemia. Oxidative stress is known to play a major role in the pathogenesis of metabolic syndrome. The objective of this study was to examine the effectiveness of hydrogen rich water (1.5–2 L/day) in an open label, 8-week study on 20 subjects with potential metabolic

It has been shown that molecular hydrogen acts as a therapeutic and preventive antioxidant by selectively reducing the hydroxyl radical, the most cytotoxic of the reactive oxygen species. In the present study, we tested the hypothesis that acoustic damage in guinea pigs can be attenuated by the consumption of molecular hydrogen. Guinea pigs received normal water or hydrogen-rich water for 14 days

PURPOSE. Retinal ischemia-reperfusion (I/R) injury by transient
elevation of intraocular pressure (IOP) is known to induce
neuronal damage through the generation of reactive oxygen
species. Study results have indicated that molecular hydrogen
(H2) is an efficient antioxidant gas that selectively reduces the
hydroxyl radical (OH) and suppresses oxidative stress-induced
injury in several organs. This

In order to erase reactive oxygen species (ROS) related with the proliferation of tumor cells by reducing activity of hydrogen, we developed functional water containing nano-bubbles (diameters: <900 nm for 71%/ population) hydrogen of 1.1-1.5 ppm (the theoretical maximum: 1.6 ppm) with a reducing ability (an oxidation- reduction potential -650 mV, normal water: +100-200 mV) using a microporous-fil

Consumption of resistant starch (RS)-enriched foods is associated with decrease in the postprandial glycaemic and insulinaemic responses, accompanied by the production of fermentation-related gases in the large bowel. The present study aimed to determine the postprandial glycaemic and insulinaemic responses to the GM RS-enriched rice and the fermentation-related production of H2 in young and healt

Oxidative stress is implicated in the pathogenesis of many diseases; however, currently used antioxidants have a high toxicity that constrains administration to a narrow window of therapeutic dosage. There is a clear need for more effective and safer antioxidants. Diatomic hydrogen (H2) was proposed as a novel antioxidant that selectively reduces levels of toxic reactive-oxygen species. Recently,

Sepsis/multiple organ dysfunction syndrome is the leading cause of death in critically ill patients. Recently, it has been suggested that hydrogen gas (H2) exerts a therapeutic antioxidant activity by selectively reducing hydroxyl radical (&OH, the most cytotoxic reactive oxygen species). We have found that H2 inhalation significantly improved the survival rate and organ damage of septic mice with
