“…Their result indicated that POD activity lowered with higher heavy metal accumulation, but CAT activity increased with higher concentration of heavy metals. Chen et al (2017) investigated the effect of hydrogen-rish waters (HRW) on the Hypsizygus marmoreus depended on storage time. According to the result of them, SOD, CAT, APX, and GR activities enhanced with 25% HRW.…”

were obtained from different locations in Turkey. Phenylalanine ammonia lyase (PAL) enzyme activity, ascorbate peroxidase (APX), peroxidase (POD), and superoxide dismutase (SOD) activity changes and nitrate, β-carotene and lycopene levels were investigated in 15 samples to determine antioxidant enzyme capacity. As a result of the study, the highest amount of β-carotene and lycopene were determined in H. erinaceus. P. ostreatus-2 had the lowest amount of β-carotene, whereas Pleurotus ostreatus-1 had the lowest amount of lycopene. Species rich in nitrate content were C. cornucopioides and P. ostreatus-4. P. ostreatus-3 was the poorest species in terms of nitrate compared to other mushroom samples. PAL activity of mushrooms varied between 5.863 and 8.893 EU mg -1 protein. For APX values, P. ostreatus-4 had the highest value, while H. erinaceus species had the lowest value. Among mushroom species, the highest and the lowest POD values were determined in H. erinaceus and B. edulis, respectively. C. cornucopioides had the highest and P. ostreatus-3 had the lowest SOD values.

Water was bubbled with gases including nitrogen (N2), oxygen (O2), hydrogen (H2), carbon dioxide (CO2), and air for 10 min and phenolics from green tea leaves were extracted using the prepared gas‐bubbled water. To retain the gases in water, the extraction conditions were maintained in an air‐tight container at room temperature under magnetic stirring. Radical scavenging ability, total phenolic content, and phenolic profiles of the extracts were analyzed, and gas‐bubbled water was examined to explain the differences in phenolic contents. Overall, green tea infusion prepared from H2‐bubbled water contained significantly high levels of total phenolic compounds and antioxidant activity compared to other gas‐bubbled waters including N2, O2, CO2, and air (P < 0.05).Control samples and those bubbled with CO2 showed the lowest antioxidant activities in green tea infusion. However, green tea extracts with O2 bubbling showed the lowest catechin content. Green tea leaves treated with hydrogen gas‐bubbled water had much greater damage to their surface morphological properties compared to the other groups, which may explain the higher yield of phenolic compounds. Overall, hydrogen gas‐bubbled water showed better extraction yield of phenolics from green tea leaves than other gas‐bubbled water. Practical Application Green tea or green tea infusion has diverse health beneficial functionality due to the presence of phenolic compounds. In this study, different gases including nitrogen, oxygen, hydrogen, and carbon dioxide were treated in water and these gas‐bubbled water were used to extract phenolics from green tea leaves. Among them, hydrogen‐bubbled water extracted the highest phenolic contents from tea leaves and showed the highest in vitro antioxidant ability in green tea infusion compared to other gas‐bubbled water. This new knowledge could help to produce green teas with higher antioxidant activity in beverage industry.

“…In recent years, hydrogen was found to be a potent antioxidant and has been widely used in the treatment of diseases in animal models and clinical trials. 24 As compared to other available antioxidants, hydrogen has some advantages: it may not disturb metabolic redox reactions or affect ROS because it mainly reacts with highly toxic ROS hydroxyl radicals and peroxynitrite; it has favorable distribution characteristics and can penetrate biomembranes and diffuse through barriers into cellular components; its metabolite (water) is not harmful to cells. Although the neuroprotective effects of hydrogen gas have been confirmed in some animal models and even in clinical trials, the concentration of hydrogen gas used is no higher than 4% due to safety concerns.…”

This study aimed to investigate the role of necroptosis in the neuroprotection of hydrogen in a mouse model of cerebral ischemia/reperfusion (I/R) injury. C57BL mice were randomly divided into sham group, I/R group, hydrogen/oxygen group (HO), nitrogen/oxygen group (NO). Middle cerebral artery occlusion (MCAO) for 1 hour followed by reperfusion was introduced to animals which were allowed to inhale 66.7% hydrogen/33.3% oxygen for 90 minutes since the beginning of reperfusion. Mice in NO group inhaled 66.7% nitrogen/33.3% oxygen. 24 hours after MCAO, brain infarction, brain water content and neurological function were evaluated. The protein expression of mixed lineage kinase domain like protein (MLKL) was detected at 3, 6, 12, 24 and 72 hours after reperfusion in HO group and the protein and mRNA expression of MLKL at 24 hours after MCAO in four groups. Hydrogen inhalation significantly reduced infarct volume, attenuated brain edema and improved neurobehavioral deficit in MCAO mice. The MLKL expression increased after MCAO and peaked at 6–24 hours after reperfusion. However, hydrogen inhalation had no significant effect on the MLKL expression at transcriptional and translational levels after MCAO. This study indicates high concentration hydrogen improves mouse neurological outcome after cerebral I/R injury independent of anti-necroptosis.
