Molecular hydrogen has an anti-inflammatory and cardioprotective effect, which is associated with its antioxidant properties. Erythrocytes are subjected to oxidative stress in pathologies of the cardiovascular system, which is the cause of a violation of the gas transport function of blood and microcirculation. Therefore, our aim was to investigate the effects of H inhalation on the functional states of red blood cells (RBCs) in chronic heart failure (CHF) in rats. The markers of lipid peroxidation, antioxidant capacity, electrophoretic mobility of erythrocytes (EPM), aggregation, levels of adenosine triphosphate (ATP) and 2,3-diphosphoglyceric acid (2,3-DPG), hematological parameters were estimated in RBCs. An increase in EPM and a decrease in the level of aggregation were observed in groups with multiple and single H application. The orientation of lipoperoxidation processes in erythrocytes was combined with the dynamics of changes in oxidative processes in blood plasma, it was observed with both single and multiple exposures, although the severity of the changes was greater with multiple H inhalations. Probably, the antioxidant effects of molecular hydrogen mediate its metabolic action. Based on these data, we conclude the use of H improves microcirculation and oxygen transport function of blood and can be effective in the treatment of CHF.

A total of 38 new benzohydrazide derivatives bearing the 4-aminoquinazoline moiety were designed and synthesized based on the active subunit combination approach and tested in detail for their inhibition activities against eight agricultural phytopathogenic fungi. The bioassay results indicated that many of the synthesized compounds exhibited extraordinary fungicidal activities in vitro against the tested fungi. For example, compounds , , , and had EC (half-maximal effective concentration) values of 0.

Metallic Zn is a promising anode for high-safety, low-cost, and large-scale energy storage systems. However, it is strongly hindered by unstable electrode/electrolyte interface issues, including zinc dendrite, corrosion, passivation, and hydrogen evolution reactions. In this work, an in situ interface protection strategy is established by turning the corrosion/passivation byproducts (zinc hydroxide sulfates, ZHSs) into a stable hybrid protection layer.

In recent years, formic acid (FA) has garnered attention as a compelling molecule for various chemical and everyday applications Additionally, with recent studies demonstrating direct FA generation through CO2 electrolysis, it can serve as a stable liquid hydrogen carrier. Nevertheless, FA-permeability via semi-permeable ion‑exchange membranes (FA-crossover) still constitutes a major issue in scalable polymer-electrolyte separated zero-gap electrolyzers, limiting the breakthrough of the technology to the larger-scale. Herein we present a holistic route towards understanding the mechanism of FA-crossover in zero-gap cells.

Herein, the interfacial effects on calcium carbonate clustering within two-dimensional (2D) graphene nanochannels were systematically investigated using molecular dynamics simulations. The distribution characteristics of the ions at the interface can be attributed to the ordered water layers within the 2D nanochannels. The orientation of CO is approximately perpendicular to the interface, which can be attributed to hydrogen bonding and its association with Ca at the interface region.

Objective: To assess the changes of thalamic metabolites before and after surgery in patients with Cervical Spondylotic Myelopathy (CSM) using Hydrogen Proton Magnetic Resonance Spectroscopy (H-MRS) and to investigate its association with improvement in neurological function.
Methods: Forty-eight CSM patients who underwent cervical decompression surgery from December 2022 to June 2023 were included, and 33 healthy volunteers were recruited. All subjects underwent bilateral thalamic H-MRS scans before the surgical procedure, and subsequently again 6 months later.
