The Effect of Deuterium Depleted/Enriched Water on the Growth of A549 and HepG2 Cell Lines
Background: Although advances in cancer therapy continue to develop, the overall survival rate is poor for some cancer cases. The search for a new adjuvant strategy is the focus of cancer treatment. There is some evidence suggesting a change in the mechanism of cell function by a change in the content of deuterium in the medium. So, the aim of this study was to investigate the ...
متن کاملDynamic Deuterium Enrichment in Cometary Water via Eley–rideal Reactions
The deuterium-to-hydrogen ratio (D/H) in water found in the coma of Jupiter family comet (JFC) 67P/ Churyumov–Gerasimenko was reported to be (5.3±0.7)×10, the highest among comets and three times the value for other JFCs with an ocean-like ratio. This discrepancy suggests the diverse origins of JFCs and clouds the issue of the origin of Earth’s oceanic water. Here we demonstrate that Eley–R...
متن کاملEffects of Low-Level Deuterium Enrichment on Bacterial Growth
Using very precise (±0.05%) measurements of the growth parameters for bacteria E. coli grown on minimal media, we aimed to determine the lowest deuterium concentration at which the adverse effects that are prominent at higher enrichments start to become noticeable. Such a threshold was found at 0.5% D, a surprisingly high value, while the ultralow deuterium concentrations (≤0.25% D) showed sign...
متن کاملDeuterium enrichment of polycyclic aromatic hydrocarbons by photochemically induced exchange with deuterium-rich cosmic ices.
The polycyclic aromatic hydrocarbon (PAH) coronene (C24H12) frozen in D2O ice in a ratio of less than 1 part in 500 rapidly exchanges its hydrogen atoms with the deuterium in the ice at interstellar temperatures and pressures when exposed to ultraviolet radiation. Exchange occurs via three different chemical processes: D atom addition, D atom exchange at oxidized edge sites, and D atom exchange...
