Effects of hydrogen rich water and pure water on periodontal inflammatory factor level, oxidative stress level and oral flora: a systematic review and meta-analysis

MHID-6169739PMID: 363888302022Annals of Translational Medicine

Yang Bai, Chenglong Wang, Hua Jiang, Lin Wang, Nan Li, Wei Zhang, et al.

Background: Hydrogen rich water (HRW) was used as an auxiliary treatment for periodontitis and peri-implantitis due to its good antioxidant properties. However, the stability of artificially added active hydrogen was far less than that of pure natural active hydrogen, which greatly reduced active hydrogen molecules number in HRW. Meanwhile, the effect of HRW was relatively slow. Finally, long-term

Neuroprotective Effects of Molecular Hydrogen: A Critical Review

MHID-9272690PMID: 330783742021Neuroscience Bulletin

Wei Chen, Han-Ting Zhang, Shu-Cun Qin

Molecular hydrogen (H2) is a physiologically inert gas. However, during the last 10 years, increasing evidence has revealed its biological functions under pathological conditions. More specifically, H2 has protec- tive effects against a variety of diseases, particularly nervous system disorders, which include ischemia/reperfu- sion injury, traumatic injury, subarachnoid hemorrhage, neuropathic pain

Molecular hydrogen protects against oxidative stress‑induced RAW 264.7 macrophage cells through the activation of Nrf2 and inhibition of MAPK signaling pathway

Rahima Begum, Cheol‑Su Kim, Ailyn Fadriquela, Johny Bajgai, Xingyu Jing, Dong‑Heui Kim, et al.

Background: Oxidative stress is involved in the development of many inflammatory, metabolic and aging diseases. Objective: In this study we investigated, the protective effects of H2 on RAW 264.7 macrophage cell against LPS-and H2O2-induced oxidative stress by the inhibition of MAPK pathway and also activate the Nrf2 pathway. Results: Our results showed H2 increased the macrophage cell prolifera

Recent Advances in Studies of Molecular Hydrogen against Sepsis

MHID-1011283PMID: 312232852019International Journal of Biological Sciences

Peng Qiu, Yang Liu, Jin Zhang

Sepsis is a syndrome comprised of a series of life-threatening organ dysfunctions caused by a maladjusted body response to infection with no effective treatment. Molecular hydrogen is a new type of antioxidant with strong free radical scavenging ability, which has been demonstrated to be effective for treating various diseases, such as infection, trauma, poisoning, organ ischemia-reperfusion, meta

Molecular hydrogen inhibits lipopolysaccharide-triggered NLRP3 inflammasome activation in macrophages by targeting the mitochondrial reactive oxygen species

MHID-1084413PMID: 264880872016Biochimica et Biophysica Acta - Molecular Cell Research

Jian-Dong Ren, Xiao-Bo Wu, Rui Jiang, Da-Peng Hao, Yi Liu

The NLRP3 inflammasome, an intracellular multi-protein complex controlling the maturation of cytokine interleukin-1β, plays an important role in lipopolysaccharide (LPS)-induced inflammatory cascades. Recently, the production of mitochondrial reactive oxygen species (mtROS) in macrophages stimulated with LPS has been suggested to act as a trigger during the process of NLRP3 inflammasome activation

Heme oxygenase-1 mediates the anti-inflammatory effect of molecular hydrogen in LPS-stimulated RAW 264.7 macrophages

MHID-1519950PMID: 241487942013International Journal of Surgery

Hong-Guang Chen, Ke-Liang Xie, Huan-Zhi Han, Wei-Na Wang, Da-Quan Liu, Guo-Lin Wang, et al.

Background: Molecular hydrogen (H2) as a new medical gas has an anti-inflammatory effect. In the present study, we investigated whether heme oxygenase-1 (HO-1) contributes to the anti-inflammatory effect of H2 in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages. Methods: RAW 264.7 macrophages were stimulated by LPS (1 mg/mL) with presence or absence of different concentrations of H2. Cell
