Background: Hydrogen-rich water (HRW) has been shown to have a stimulating effect on the human body. Objective: The aim of study was assess influence acute HRW intake autonomic cardiac regulation during 50 min rest sitting. Methods: Fourteen healthy females (age 21.7 ± 1.2 years, body mass 67.8 8.7 kg, height 167 5.5 cm) took part in this double-blind, randomized, placebo-controlled trial with ...

Determining how to apply hydrogen as a therapeutic/preventive antioxidant for oxidative-stress-related diseases practically in daily life has not been studied. The effects of bathtubs and buckets filled with water (41 °C, >10 min bathing) were investigated on six subjects, without medical prescription, suffering from skin roughness the foot, hand, finger, or elbow. They also treated an elect...

The discovery of hydrogen-rich waters preserved below the Earth's surface in Precambrian rocks worldwide expands our understanding of the habitability of the terrestrial subsurface. Many deep microbial ecosystems in these waters survive by coupling hydrogen oxidation to sulfate reduction. Hydrogen originates from water-rock reactions including serpentinization and radiolytic decomposition of wa...

Hydrogen exerts beneficial effects in disease animal models of ischemia-reperfusion injury as well as inflammatory and neurological disease. Additionally, molecular hydrogen is useful for various novel medical and therapeutic applications in the clinical setting. In the present study, the hydrogen concentration in rat blood and tissue was estimated. Wistar rats were orally administered hydrogen...

a fragment of histidine rich protein ii (hrp ii 215-236) was investigated by 14n and 17o electric field gradient, efg, tensor calculations using dft. this study is intended to explore the differences between 310-helix and α-helix of hrpii both in the gas phase and in solution. to achieve the aims, the 17o and 14n nqr parameters of a fragment of hrpii (215-236) for both structures are calculated...

The 3-methylindole (3MI) oxygenation sensitized by psoralen (PSO) has been investigated in 100%, 20% and 5% O 2 -saturated water/ dioxane (H 2 O/Dx) mixtures. The lowering of the O 2 * chemical rate when water (k chem 3MI = 1.4 109 M s) is replaced by deuterated water (k chem 3MI = 1.9 108 M s) suggests that hydrogen abstraction is involved in the rate determining step. A high dependence of the...

The plethora of ice structures observed both in bulk and under nanoscale confinement reflects the extraordinary ability of water molecules to form diverse forms of hydrogen bonding networks. An ideal hydrogen bonding network of water should satisfy three requirements: (1) four hydrogen bonds connected with every water molecule, (2) nearly linear hydrogen bonds, and (3) tetrahedral configuration...
