Delivery of Molecular Hydrogen for Precision Immunomodulation: Mechanisms, Detection Methods, and Applications

MHID-1191317PMID: 406196052025Advanced Science

Gangfeng Li, Hannan Cui, Ruixiao Fan, Guming Liu, Zishuo Hou, Yibo Zhang, et al.

The delivery of molecular hydrogen (H2) is increasingly recognized for its potential in precision immunomodulation, primarily through multiple pathways such as antioxidant action, modulation of inflammatory factors, and inhibition of apoptosis. These effects contribute to a balanced and functional immune system, highlighting the therapeutic promise of H2 in various inflammatory conditions. However, t

Molecular hydrogen as a novel regulator of cellular pyroptosis: mechanistic insights and therapeutic implications

MHID-3242181PMID: 405693542025Molecular Biology Reports

Yong Ye, Zi-hang Yu, Liang Nie, Bin Lu, Guo Mu

Pyroptosis, a highly inflammatory programmed cell death pathway, drives pathogenesis in numerous diseases through gasdermin-mediated membrane pore formation and massive cytokine release. While conventional anti-inflammatory therapies show limited efficacy, hydrogen emerges as a novel therapeutic agent with unique pyroptosis-regulatory capabilities. This review establishes a comprehensive mechanist

Using oral molecular hydrogen supplements to combat microinflammation in humans: a pilot observational study

MHID-3946150PMID: 393102562024International Journal of Medical Sciences

Kuo-Cheng Lu, Min-Chung Shen, Reui-Lin Wang, Wen-Wen Chen, Szu-Han Chiu, Yung-His Kao, et al.

Background: Persistent inflammation over time can cause gradual harm to the body. Molecular hydrogen has the potential to specifically counteract reactive oxygen species (ROS), reduce disease severity, and enhance overall health. Investigations of the anti-inflammatory and antioxidant properties of oral solid hydrogen capsules (OSHCs) are currently limited, prompting our examination of the benefic

Therapeutic Potential of Molecular Hydrogen in Metabolic Diseases from Bench to Bedside

MHID-9342689PMID: 371112992023Pharmaceuticals

Fei Xie, Yifei Song, Yang Yi, Xue Jiang, Shiwen Ma, Chen Ma, et al.

Oxidative stress and chronic inflammation have been implicated in the pathophysiology of metabolic diseases, including diabetes mellitus (DM), metabolic syndrome (MS), fatty liver (FL), atherosclerosis (AS), and obesity. Molecular hydrogen (H2) has long been considered a physiologically inert gas. In the last two decades, accumulating evidence from pre-clinical and clinical studies has indicated th

Social Communication of Maternal Immune Activation-Affected Offspring Is Improved by Si-Based Hydrogen-Producing Agent

MHID-1698660PMID: 354927052022Frontiers in Psychiatry

Noriyoshi Usui, Kazumasa Matsumoto-Miyai, Yoshihisa Koyama, Yuki Kobayashi, Yukiko Nakamura, Hikaru Kobayashi, et al.

Maternal immune activation (MIA) is triggered by infection or autoimmune predisposition during pregnancy, and cytokines produced by MIA are transmitted through the placenta to the fetal brain, implicating at the onset risks and vulnerability for developmental and psychiatric disorders, such as autism spectrum disorder (ASD) and schizophrenia. To address these kinds of problem in child health, we h

Silicon nanoparticles for oral administration of molecular hydrogen

MHID-8624125PMID: 363515042022International Journal of Pharmaceutics

Hennie Marie Johnsen, Werner Filtvedt, Marianne Hiorth, Jo Klaveness

Medical use of hydrogen gas (H2) has been given increasing attention over the past 15 years with numerous clinical trials for a variety of indications. The biological activity of H2 includes antioxidant properties and thereby the ability to neutralize damaging reactive oxygen species (ROS). Administration of hydrogen as a medical gas is limited by the poor water solubility and by the flammability

Molecular Hydrogen as Medicine: An Assessment of Administration Methods

MHID-48068842021Hydrogen

Grace Russell, Alexander Nenov, Hesham Kisher, John T. Hancock

Since the late 18th century, molecular hydrogen (H2) has been shown to be well tolerated, firstly in animals, and then in humans. However, although research into the beneficial effects of molecular hydrogen in both plant and mammalian physiology is gaining momentum, the idea of utilising this electrochemically neutral and non-polar diatomic compound for the benefit of health has yet to be widely acce

Renoprotective and neuroprotective effects of enteric hydrogen generation from Si-based agent

MHID-1878579PMID: 322460952020Scientific Reports

Yuki Kobayashi, Ryoichi Imamura, Yoshihisa Koyama, Makoto Kondo, Hikaru Kobayashi, Norio Nonomura, et al.

We have developed Si-based agent which can generate a large amount of hydrogen. Si-based agent continues generating hydrogen for more than 24 h by the reaction with water under conditions similar to those in bowels, i.e., pH8.3 and 36 °C, and generates ~400 mL hydrogen. To investigate beneficial effects for diseases associated with oxidative stress, Si-based agent is administered to remnant kidney

MHID-9868845PMID: 285605192018Irish Journal of Medical Science

D. Korovljev, T. Trivic, P. Drid, S. M. Ostojic

Background: Molecular hydrogen (H2) effectively treats obesity-related disorders in animal models, yet no studies have investigated the effectiveness and safety of H2 for improving biomarkers of obesity in humans. Aim: In this double blind, placebo-controlled, crossover pilot trial, we evaluated the effects of H2 intervention on body composition, hormonal status, and mitochondrial function in ten
