Clostridium beijerinckii displays a soluble [FeFe]-hydrogenase/formate dehydrogenase enzyme complex that links H2 and CO2 metabolism

MHID-0389345PMID: 415753722026Biochemical Journal

Sabrina Dezzani, Abdulrahman Alogaidi, Anca Pordea, Simone Morra

The production of biofuels by bacterial fermentation receives sustained attention due to the need to develop novel circular and sustainable technologies. Clostridium beijerinckii produces both hydrogen (H2) and carbon-based biofuels acetone, butanol and ethanol (ABE solvents). H2 metabolism in C. beijerinckii is complex and mostly unexplored. Seven hydrogenase genes are contained in the genome, bu

Prospects of Hydrogen Medicine Based on Its Protective Effects on Mitochondrial Function

MHID-44233202024Molecular Hydrogen in Health and Disease, Advances in Biochemistry in Health and Disease

Shin-ichi Hirano, Yusuke Ichikawa, Bunpei Sato, Yoshiyasu Takefuji, Xiao-Kang Li, Fumitake Satoh

Mitochondria originated from aerobic bacteria in endosymbiosis. Through this symbiosis, eukaryotes acquired an efficient energy-producing system, but at the cost of exposure to oxidative stress from reactive oxygen species (ROS). Molecular hydrogen (H2) was recently identified as an antioxidant that selectively reduces ROS, such as hydroxyl radicals and peroxynitrite, which are strong oxidants, and

A strategy of local hydrogen capture and catalytic hydrogenation for enhanced therapy of chronic liver diseases

MHID-1279019PMID: 372155682023Theranostics

Geru Tao, Feng Liu, Zhaokui Jin, Boyan Liu, Hao Wang, Daosheng Li, et al.

Background: Chronic liver diseases (CLD) frequently derive from hepatic steatosis, inflammation and fibrosis, and become a leading inducement of cirrhosis and hepatocarcinoma. Molecular hydrogen (H2) is an emerging wide-spectrum anti-inflammatory molecule which is able to improve hepatic inflammation and metabolic dysfunction, and holds obvious advantages in biosafety over traditional anti-CLD dru

Anti-Oxidative and Anti-Diabetic Effects of Electrolyzed Weakly Alkaline Reduced Water on Renal Proximal Tubular Epithelial Cells

MHID-02613512022Processes

Subham Sharma, Kyu-Jae Lee, Johny Bajgai, Thuy Thi Trinh, Jayson M. Antonio, Md. Habibur Rahman, et al.

Diabetes, a chronic metabolic disorder, affects glucose consumption in the body and leads to severe kidney damage, known as diabetic nephropathy, where oxidative stress (OS) plays a vital role in disease pathogenesis. Electrolyzed weakly alkaline reduced water (EWARW) is known to have anti-oxidative functions in vitro due to its bioactive properties. However, there is an increasing need for adequa

A randomized, placebo-controlled clinical trial of hydrogen/oxygen inhalation for non-alcoholic fatty liver disease

MHID-2649268PMID: 357349742022Journal of Cellular and Molecular Medicine

Geru Tao, Guangjie Zhang, Wei Chen, Chao Yang, Yazhuo Xue, Guohua Song, et al.

Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease worldwide with increasing incidence consistent with obesity, type 2 diabetes and cardiovascular diseases. No approved medication was currently available for NAFLD treatment. Molecular hydrogen (H2), an anti-oxidative, anti-inflammatory biomedical agent is proved to exhibit therapeutic and preventive effect in variou

Long‑term and daily use of molecular hydrogen induces reprogramming of liver metabolism in rats by modulating NADP/NADPH redox pathways

MHID-2655528PMID: 352732492022Scientific Reports

Yao Mawulikplimi Adzavon, Fei Xie, Yang Yi, Xue Jiang, Xiaokang Zhang, Jin He, et al.

Molecular hydrogen (H2) has emerged as a new therapeutic option in several diseases and is widely adopted by healthy people. However, molecular data to support therapeutic functions attributed to the biological activities of H2 remain elusive. Here, using transcriptomic and metabolomic approaches coupled with biochemistry and micro-CT technics, we evaluated the effect of long-term (6 months) and d

Hydrogen Evolution and Absorption Phenomena in the Plasma Membrane of Vigna radiata and Capsicum annuum

MHID-32438852021Journal of Plant Growth Regulation

Xin Zhang, Fei Xie, Zhao Zhang, Yao Mawulikplimi Adzavon, Zehua Su, Qinghui Zhao, et al.

Molecular hydrogen has been shown to exert beneficial effects on plant growth and abiotic stress tolerance, however, the exact mechanism has not yet been fully elucidated. H2 is able to diffuse directly across the plasma membrane, which is the first barrier between H2 and cells. It is possible that H2 may exert its biological effects on plant cells by interacting with PM. Hydrogenases can catalyze

Molecular hydrogen attenuates fatty acid uptake and lipid accumulation through downregulating CD36 expression in HepG2 cells

MHID-9934004PMID: 234482062013Medical Gas Research

Akio Iio, Mikako Ito, Tomohiro Itoh, Riyako Terazawa, Yasunori Fujita, Yoshinori Nozawa, et al.

Background: There is accumulating evidence that obesity is closely associated with an impaired free fatty acid metabolism as well as with insulin resistance and inflammation. Excessive fatty acid uptake mediated by fatty acid translocase CD36 plays an important role in hepatic steatosis. Molecular hydrogen has been shown to attenuate oxidative stress and improve lipid, glucose and energy metabolis
