Molecular hydrogen application in stroke

In Review papers by CHESS

Stroke is a major cause of mortality and morbidity worldwide. Effective treatments are limited. Molecular hydrogen is emerging as a novel medical gas with therapeutic potential for various neurological diseases, including stroke. We reviewed the experimental and clinical findings of the effects of molecular hydrogen therapy in stroke patients and models. The underlying neuroprotective mechanisms against stroke pathology were also …

Hydrogen gas as an exotic performance-enhancing agent

In Review papers by CHESS

Hydrogen gas (H2 ) has entered the world of experimental therapeutics approximately four and a half decades ago. Over the years, this simple molecule appears to drive more and more scientific attention perhaps due to a dualism of H2 affirmative features demonstrated in numerous in vitro, animal and human studies on one side, and stillpuzzling mechanism(s) of its biological activity …

Hydrogen in mitigating oxidative-stress-induced radiation injury

In Review papers by CHESS

Uncontrolled production of oxygen and nitrogen radicals results in oxidative and nitrosative stresses that impair cellular functions and have been regarded as causative common denominators of many pathological processes. In this review, we report on the beneficial effects of molecular hydrogen in scavenging radicals in an artificial system of •OH formation. As a proof of principle, we also demonstrate that …

Hydrogen-rich saline for eye diseases

In Review papers by CHESS

As an antioxidant, hydrogen-rich water has been widely studied in recent years. It is mild enough neither to disturb metabolic redox reactions nor to affect signaling reactive oxygen species. Therefore, there should be no or few adverse effects of H(2). Numerous studies in biology and medicine show that hydrogen-rich water has achieved good results in nervous system, digestive system, respiratory …

Hydrogen-rich saline for neonatal hypoxic-ischemic encephalopathy

In Review papers by CHESS

Neonatal hypoxic ischemic encephalopathy (HIE) is an important cause of neonatal death and disability. At present, there is no unified standard and specialized treatment method for neonatal HIE. In clinical practice, the authors have found that a gap remains between preclinical medical research and clinical application in the treatment of neonatal HIE. To promote an organic combination of preclinical research …

Molecular hydrogen for neuroprotection

In Review papers by CHESS

Oxidative stress and neuroinflammation cause many neurological disorders. Recently, it has been reported that molecular hydrogen (H2) functions as an antioxidant and anti-inflammatory agent. The routes of H2 administration in animal model and human clinical studies are roughly classified into three types, inhalation of H2 gas, drinking H2-dissolved water, and injection of H2-dissolved saline. This review discusses some of the …

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 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. …

Hydrogen as a therapeutic strategy against ocular diseases

In Review papers by CHESS

Hydrogen, one of the most well-known natural molecules, has been used in numerous medical applications owing to its ability to selectively neutralize cytotoxic reactive oxygen species and ameliorate hazardous inflammations. Hydrogen can exert protective effects on various reactive oxygen species-related diseases, including the transplantation-induced intestinal graft injury, chronic inflammation, ischemia-reperfusion injuries, and so on. Especially in the eye, hydrogen has …

Melanin as a possible source of bioactive molecular hydrogen

In Review papers by CHESS

Molecular hydrogen (dihydrogen; H2) has traditionally been described as a biologically inactive gas, with low capacity to react with most biomolecules. However, in the past two decades hydrogen emerged as a potent therapeutic agent, with antioxidant, anti-inflammatory and anti-apoptotic effects demonstrated in a plethora of animal disease models and human studies. Prominent effects of supplemental H2 in clinical environment are …
