Neuroprotective potential of molecular hydrogen against perinatal brain injury

In Animal studies, Nervous system by CHESS

Exposure to inflammation in utero is related to perinatal brain injury, which is itself associated with high rates of long-term morbidity and mortality in children. Novel therapeutic interventions during the perinatal period are required to prevent inflammation, but its pathogenesis is incompletely understood. Activated microglia are known to play a central role in brain injury by producing a variety of …

Molecular hydrogen inhibits lipopolysaccharide-triggered NLRP3 inflammasome activation

In In vitro studies by CHESS

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 that can be blocked by some mitochondria-targeted antioxidants. Known …

Immersing lungs in hydrogen-rich saline attenuates ischaemia–reperfusion injury

In Animal studies, Lung by CHESS

Anti-oxidant effects of hydrogen have been reported in studies examining ischaemia–reperfusion injury (IRI). In this study, the authors evaluated the therapeutic efficacy of immersing lungs in hydrogen-rich saline on lung IRI. Lewis rats were divided into three groups: (i) sham, (ii) normal saline and (iii) hydrogen-rich saline. In the first experiment, the left thoracic cavity was filled with either normal …

Molecular hydrogen decelerates rheumatoid arthritis progression

In Animal studies, Inflammation by CHESS

Rheumatoid arthritis (RA) is a chronic inflammatory disease which results in progressive destruction of the joint. In this study, the authors examined if the hydrogen could inhibit inflammation in a mouse model of collagen-induced arthritis (CIA) via oxidative stress on RA-FLSs. Moreover, to identify the mechanisms of action, the authors evaluated the effect of hydrogen on RA-FLSs development and the …

Protective effects of hydrogen against low-dose long-term radiation

In Animal studies, Other studies by CHESS

Molecular hydrogen (H2) has been previously reported playing an important role in ameliorating damage caused by acute radiation. In this study, the authors investigated the effects of H2 on the alterations induced by low-dose long-term radiation (LDLTR). All the mice in hydrogen-treated or radiation-only groups received 0.1 Gy, 0.5 Gy, 1.0 Gy, and 2.0 Gy whole-body gamma radiation, respectively. After the last time of …

Clinical application of molecular hydrogen in hemodialysis

In Review papers by CHESS

Increased oxidative stress and pro-inflammatory conditions, commonly present in chronic dialysis patients, are thought to be enhanced during hemodialysis (HD) and to be associated with the excess morbidity and mortality seen in these patients. The hydrogen molecule (H2) has a unique biological capacity to act as an antioxidative and anti-inflammatory substance. In light of accumulating evidence from animal studies showing …

Hydrogen-rich medium ameliorates lipopolysaccharide-induced barrier dysfunction

In In vitro studies by CHESS

Gastrointestinal barrier dysfunction is associated with the severity and prognosis of sepsis. Hydrogen gas (H2) can ameliorate multiple organ damage in septic animals. Ras homolog gene family member A (RhoA) and mammalian diaphanous-related formin 1 (mDia1) are important to regulate tight junction (TJ) and adherens junction (AJ), both of which determine the integrity of the intestinal barrier. This study was …

Hydrogen as a therapeutic strategy against photoreceptor degeneration

In Review papers by CHESS

Retinitis pigmentosa (RP) is a heterogeneous group of inherited retinal dystrophies characterized by progressive photoreceptor apoptosis. Reactive oxygen species (ROS) have been recognized as critical initiators of the photoreceptor apoptosis in RP. Photoreceptor survival in RP mutants will not only require the inhibition of effectors of apoptotic machinery, but also the elimination of the initiating upstream signals, such as ROS. …

Neuroprotective effect of hydrogen gas on brain injury

In Animal studies, Nervous system by CHESS

Hydrogen gas is widely considered to be a novel antioxidant. It has been demonstrated that inhalation of hydrogen gas reduced ischemic cerebral injury in several investigations. However, it remains unclear whether the neuroprotective effect of hydrogen gas is reproducible in a rat transient forebrain ischemia model. The current study was conducted to evaluate the effect of hydrogen gas on histological …

Lung inflation with hydrogen reduced lung injury

In Animal studies, Lung by CHESS

Lung ischemia-reperfusion injury (IRI) may be attenuated through carbon monoxide (CO)’s anti-inflammatory effect or hydrogen (H2)’s anti-oxidant effect. In this study, the effects of lung inflation with CO, H2, or both during the cold ischemia phase on graft function were observed. Rat donor lungs, inflated with 40% oxygen (control group), 500ppm CO (CO group), 3% H2 (H2 group) or 500ppm …
