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

The aim of the review was to examine the main characteristics of hydrogen ion metabolism and its hemostatic function in the human body. For diagnostic purposes, molecular hydrogen (H2) is considered a biological marker. The results of the analysis of therapeutic programs for the clinical use of hydrogen are presented. The use of H2 as a drug in the treatment of more than 170 diseases is also discu

In regenerative medicine, mesenchymal stem cells (MSCs) have shown their importance and potential in tissue reconstruction and immune system modification. However, such cells’ potential is often diminished by factors such as oxidative stress, immune rejection, and inadequate engraftment.

A 62-year-old woman was diagnosed with postoperative breast cancer recurrence. While inhaling hydrogen gas through a nasal cannula at home, she used a heat-therapy machine that emitted electromagnetic waves to the breast cancer site. She suddenly experienced explosive sounds in her chest and smelled burning. Subsequently, she experienced several overlapping hemoptysis episodes and was referred to

Background: Inhalation of hydrogen gas (H2) as an antioxidant supplement may alleviate exercise-induced oxidative damage and protect post-exercise hydrogen peroxide signaling, which may help mediate beneficial exercise adaptation. The aims of this study were to determine the effects of H2 inhalation on plasma nitric oxide (NO) level and its synthesis precursor in professional athletes.
