Alzheimer's disease (AD) is characterised as a provoked inflammatory response and oxidative stress along with amyloid β peptide (Aβ) deposition and neurofibrillary tangles in the brain, and effective treatment is greatly needed. Molecular hydrogen, which has been proposed to be an antioxidant that selectively reduces reactive oxygen species, was found to exert beneficial effects in Aβ injection-in

AIM To identify the effect of hydrogen-rich water (HRW) and electrolyzed-alkaline water (EAW) on high-fat-induced non-alcoholic fatty acid disease in mice.
METHODS Mice were divided into four groups: (1) Regular diet (RD)/regular water (RW); (2) high-fat diet (HFD)/RW; (3) RD/EAW; and (4) HFD/EAW. Weight and body composition were measured. After twelve weeks, animals were sacrificed, and livers w

Recent studies have revealed unique biological characteristics of molecular hydrogen (H2) as an anti-inflammatory agent. We developed a novel haemodialysis (E-HD) system delivering an H2 (30–80 ppb)-enriched dialysis solution by water electrolysis, and conducted a non-randomized, non-blinded, prospective observational study exploring its clinical impact. Prevalent chronic HD patients were allocate

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

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

Background: Molecular hydrogen exerts its effect on multiple pathologies, including oxidative stress, inflammation, and apoptosis. However, its molecular mechanisms have not been fully elucidated. In order to explore the effects of molecular hydrogen, we meta-analyzed gene expression profiles modulated by molecular hydrogen.

Since the discovery of molecular hydrogen (H2) as a selective scavenger of free radicals like reactive oxygen species (ROS) and reactive nitrogen species (RNS), numerous studies have proved the potential application of H2 in therapeutic and preventative medicine. Moreover, H2 can regulate the intracellular signal as a signal modulator. However, it is still unclear in cell signaling involved in tes

Dysbiosis of the gut flora accompanies Parkinson disease (PD), yet no specific cause-effect link has been identified so far. The gut microbiota produce molecular hydrogen (H2), a ubiquitous molecule recently recognized as a biologically active gas with antioxidant, antiapoptotic, anti-inflammatory, cytoprotective, and signaling properties. Here, we discuss an idea that an impaired production of en

The human gut microbiome refers to a highly diverse microbial ecosystem, which has a symbiotic relationship with the host. Molecular hydrogen (H2) and carbon dioxide (CO2) are generated by fermentative metabolism in anaerobic ecosystems. H2 generation and oxidation coupled to CO2 reduction to methane or acetate help maintain the structure of the gut microbiome. Bile acids are synthesized by hepato

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.

Molecular hydrogen (H2) has been recently introduced as an experimental medical gas in clinical medicine [1]. Beneficial effects of H2 are attributed to its antioxidant, anti-apoptotic and anti-inflammatory properties, with H2 administered via oral, parenteral or inhalational route found beneficial in cardiometabolic disorders [2]. However, no information is currently available concerning its effi
