Quantification of hydrogen production by intestinal bacteria that are specifically dysregulated in Parkinson’s disease

MHID-67149392018PLoS ONE

Anzu Suzuki, Mikako Ito, Tomonori Hamaguchi, Hiroshi Mori, Yuka Takeda, Ryuko Baba, et al.

Oral administration of hydrogen water ameliorates Parkinson’s disease (PD) in rats, mice, and humans. We previously reported that the number of putative hydrogen-producing bacte- ria in intestinal microbiota is low in PD compared to controls. We also reported that the amount of hydrogen produced by ingestion of lactulose is low in PD patients. The decreased hydrogen production by intestinal microb

Masaaki Hirayama, Mikako Ito, Tomomi Minato, Asako Yoritaka, Tyler W. LeBaron, Kinji Ohno

Hyposmia is one of the earliest and the most common symptoms in Parkinson’s disease (PD). The benefits of hydrogen water on motor deficits have been reported in animal PD models and PD patients, but the effects of hydrogen gas on PD patients have not been studied. We evaluated the effect of inhalation of hydrogen gas on olfactory function, non-motor symptoms, activities of daily living, and urinar

Molecular hydrogen as a new selective anti-oxidation therapeutic medical gas for clinical research

MHID-31863052018Asia-Pacific Journal of Blood Types and Genes

Jinqi Li, Yan Zang, Haihui Gu, Baohua Qian

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

In Japan, alkaline electrolyzed water (AEW) apparatus have been approved as a medical device. And for the patients with gastrointestinal symptoms, drinking AEW has been found to be effective in relieving gastrointestinal symptoms. But some users of AEW apparatus do not have abdominal indefinite complaint. Little attention has been given to the benefit for the users which have no abdominal indefini

Molecular hydrogen potentiates beneficial anti-infarct effect of hypoxic postconditioning in isolated rat hearts: Novel cardioprotective intervention

Marek Zálešák, Branislav Kura, Ján Graban, Veronika Ledvényiová-Farkašová, Jan Slezak, Tatiana Ravingerova

Generation of free radicals through incomplete reduction of oxygen during ischemia/ reperfusion is well-described. On the other hand, molecular hydrogen (H2) reduces oxidative stress due to its ability to react with strong oxidants and easily penetrate cells by diffusion, without disturbing metabolic redox reactions. This study was designed to explore cardioprotective potential of hypoxic postcond

Hydrogen gas protects IP3Rs by reducing disulfide bridges in human keratinocytes under oxidative stress

MHID-1014265PMID: 286201982017Scientific Reports

Ching-Ying Wu, Wen-Li Hsu, Ming-Hsien Tsai, Jui-Lin Liang, Jian-He Lu, Chia-Jung Yen, et al.

Based on the oxidative stress theory, aging derives from the accumulation of oxidized proteins induced by reactive oxygen species (ROS) in the cytoplasm. Hydrogen peroxide (H2O2) elicits ROS that induces skin aging through oxidation of proteins, forming disulfide bridges with cysteine or methionine sulfhydryl groups. Decreased Ca2+ signaling is observed in aged cells, probably secondary to the for

Masaaki Nakayama, Noritomo Itami, Hodaka Suzuki, Hiromi Hamada, Naoyuki Osaka, Ryo Yamamoto, et al.

Background and aim: It is supposed that enhanced oxidative stress and inflammation are involved with the poor clinical outcomes in patients on chronic dialysis treatment. Recent studies have shown that molecular hydrogen (H2) is biologically active as an anti-inflammatory agent. Thus, we developed a novel hemodialysis (E-HD) system which delivers H2 (30 to 80 ppb)-enriched dialysis solution, to co

Yusuke Yoshii, Taikai Inoue, Yuya Uemura, Yusaku Iwasaki, Toshihiko Yada, Yusaku Nakabeppu, et al.

Molecular hydrogen (H2), as a new medical gas, has protective effects in neurological disorders including Parkinson’s disease (PD). In our previous report, the neuroprotective effect of drinking water with saturated H2 (H2 water) in PD mice might be due to stomach–brain interaction via release of gastric hormone, ghrelin. In the present study, we assessed the effect of H2-induced ghrelin more prec

Inhalation of molecular hydrogen (H2) gas ameliorates oxidative stress-induced acute injuries in the brain. Consumption of water nearly saturated with H2 also prevents chronic neurodegenerative diseases including Parkinson’s disease in animal and clinical studies. However, the molecular mechanisms underlying the remarkable effect of a small amount of H2 remain unclear. Here, we investigated the ef

Toshiki Yoneda, Takaaki Tomofuji, Muneyoshi Kunitomo, Daisuke Ekuni, Koichiro Irie, Tetsuji Azuma, et al.

Obesity induces gingival oxidative stress, which is involved in the progression of alveolar bone resorption. The antioxidant effect of hydrogen-rich water may attenuate gingival oxidative stress and prevent alveolar bone resorption in cases of obesity. We examined whether hydrogen-rich water could suppress gingival oxidative stress and alveolar bone resorption in obese rats fed a high-fat diet. Ma
