[Alleviating effects of hydrogen on hyperhomocysteinemia and fatty liver induced by high-methionine diet].

Compared with the HMD group rats, the HMD+HRW group rats showed a significant decrease in Hcy in the blood, reduced liver damage, and increased Hcy metabolism key enzyme activity and mRNA expression in the liver, with statistical differences. These results are preclinical and suggest molecular hydrogen's therapeutic potential in the condition studied. Further human research is needed to establish clinical effectiveness.

Zn-Fe primary battery-enabled controlled hydrogen release in stomach for improving insulin resistance in obesity-associated type 2 diabetes.

In vivo monitoring results show that H₂ generated by Zn-Fe micro-/nano-structure in stomach can effectively accumulate in IR-sited tissues including liver, adipose tissue, and skeletal muscle at a high dose for a relatively long time compared to H₂-rich water drinking. These results are preclinical and suggest molecular hydrogen's therapeutic potential in the condition studied. Further human research is needed to establish clinical effectiveness.

Effects of hydrogen-rich water on depressive-like behavior in mice.

In an animal model, cUMS induced elevation in IL-1β protein levels in the hippocampus, and the cortex was significantly attenuated after 4 weeks of feeding the mice hydrogen-rich water. These results are preclinical and suggest molecular hydrogen's therapeutic potential in the condition studied. Further human research is needed to establish clinical effectiveness.

The On/Off History of Hydrogen in Medicine: Will the Interest Persist This Time Around?

This narrative review examined the available molecular-hydrogen literature. Over 2000 publications including more than 100 human studies seem to indicate that humans have only recently benefited from or known about the medical effects of H₂ within the past 15 years. The reviewed evidence supports molecular hydrogen's therapeutic potential. Additional well-designed studies are needed to clarify clinical safety and effectiveness.

Hydrogen-rich water enhances vegetable growth and fruit quality by regulating ascorbate biosynthesis.

HRW-irrigated cucumber fruit showed a 15-20 % increase in vitamin C (ascorbic acid) content, a 10-15 % rise in soluble sucrose levels, and an increase in fruit weight and diameter by 25-35 % and 8-12 %, respectively.

Hydrogen-rich water prepared by ammonia borane can enhance rapeseed (Brassica napus L.) seedlings tolerance against salinity, drought or cadmium.

The application of 1 mM tungstate, an inhibitor of nitrate reductase (NR; an important NO synthetic enzyme), showed the similar blocking responses in the phenotype, suggesting that NR might be the major source of NO involved in above H₂ actions.

Hydrogen-rich water treatment increased several phytohormones and prolonged the shelf life in postharvest okras.

Meanwhile, increased transcripts of anabolic genes but lower expression of catabolic genes involved in indoleacetic acid (IAA) and gibberellin (GA) metabolism were observed in okras when treated with HRW, which was related to the enhanced levels of IAA and GA.

Photocatalytic glucose depletion and hydrogen generation for diabetic wound healing.

In a laboratory model, high-glucose microenvironment in the diabetic foot ulcer (DFU) causes excessive glycation and induces chronic inflammation, leading to the difficulty of DFU healing. These findings come from a laboratory model and suggest molecular hydrogen's biological potential. Further research is needed to determine clinical relevance.
