Oxidative stress is a key factor in the development of chronic heart failure (CHF). Molecular hydrogen (H2) exhibits antioxidant properties, yet the mechanisms by which it alleviates hemodynamic disturbances and ischemic myocardial injury in CHF are not fully under- stood. This study examined the effects of a single (40-min) and multiple (40-min daily for 5 days) inhalations of H2 in a rat model o

Background and Purpose: Sepsis-induced cardiomyopathy (SIC) is the primary cause of mortality among people with sepsis. Hydrogen (H2) has a cardioprotective effect in SIC; however, its specific mechanism remains unclear. We thus explored whether 2% H2 treatment mitigates SIC through inhibiting Golgi stress and investigated the specific molecular pathways underlying this protective effect.

Heart failure (HF) is increasing in prevalence in many countries around the world. HF is a complex clinical syndrome characterized by the heart’s inability to pump blood effectively, resulting in significant morbidity and mortality. After an initial cardiac event (e.g., myocardial infarction, valve dysfunction, hypertension, etc.), adaptive mechanisms are activated to preserve cardiac function. Su

Oxidative stress is responsible for the pathogenesis of many diseases, and antioxidants are commonly included in their treatment protocols. Over the past two decades, numerous biomedical reports have revealed the therapeutic benefits of molecular hydrogen (H2) in relieving oxidation-related diseases. H2 has been found to have selective antioxidant properties against the most dangerous oxidants (hy

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

Background: Approximately 40 to 60% of patients with sepsis develop sepsis-induced cardiomyopathy (SIC), which is associated with a substantial increase in mortality. We have found that molecular hydrogen (H2) inhalation improved the survival rate and cardiac injury in septic mice. However, the mechanism remains unclear.

Disproportion between reactive oxygen species (ROS) production and the body's antioxidant system can cause oxidative stress, which is considered a common denominator in various pathological conditions, including cardiovascular diseases, aging, and cognitive disorders. The generation of free radicals, which occurs through partial reduction of oxygen, can quickly overwhelm the endogenous antioxidant

Hydrogen has been shown to exhibit selective antioxidant properties against hydroxyl radicals, and exerts antioxidant and anti-inflammatory effects. The monocrotaline-induced model of pulmonary hypertension is suitable for studying substances with antioxidant activity because oxidative stress is induced by monocrotaline.
