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 کاملDEUTERIUM STUDIES IN THE DISPROPORTIONATION OF THIOXANTHYLIUM SALTS
Deuterium labelling is used to show that the disproportionation of thioxanthylium salts involve transfer of a hydride, (deuteride) ion from the9-positionof one molecule of the compound, as its hydro], to the 9 - position of another molecule in the cation form
متن کاملRevealing deuterium Balmer lines in H II regions with VLT - UVES ?
The search for deuterium Balmer lines with VLTUVES is reported in H ii regions of the Galaxy and the Magellanic Clouds. The D i lines appear as faint, narrow emission features in the blue wings of the H i Balmer lines and can be distinguished from high-velocity H i emission. The previous identification to deuterium is re-inforced beyond doubt. The detection of Dα and Dβ in Orion (Hébrard et al....
متن کاملPre-Clinical and Clinical Data Confirm the Anticancer Effect of Deuterium Depletion
The two stable isotopes of hydrogen, protium (1H) and deuterium (2H) differ in their physicochemical nature. Deuterium-depleted water (DDW) significantly inhibited the growth rate of different tumor cell lines in culture media and xenotransplanted MDA-MB-231, MCF-7 human breast adenocarcinomas and PC-3 human prostate tumors in vivo. The apoptosis-triggering effect of DDW was demonstrat...
متن کاملDetection of deuterium Balmer lines in the Orion Nebula ⋆
The detection and first identification of the deuterium Balmer emission lines, Dα and Dβ, in the core of the Orion Nebula is reported. These lines are very narrow, have identical 11 km s velocity shifts with respect to Hα and Hβ, are probably excited by UV continuum fluorescence from the Lyman (D i) lines and arise from the interface between the H ii region and the molecular cloud.
