1 cze 2024 · Alterations in microRNA expression by radon in human bronchial epithelial cells are mainly up-regulation of miR-15, miR-16, miR-19, miR-23, miR-125 and down-regulation of let-7, miR-124, miR-146, miR-194, miR-369, miR-373, miR-652 (Bersimbaev et al., 2020). These alterations lead to altered DNA methylation, cell cycle, oxidative stress ...
5 lip 2013 · Suggested effects produced as a result of alpha particle exposure from radon include mutations, chromosome aberrations, generation of reactive oxygen species, modification of the cell cycle, up or down regulation of cytokines and the increased production of proteins associated with cell-cycle regulation and carcinogenesis.
The exposure of cells to densely ionizing radiation, such as radon alpha particles, can initiate a series of molecular and cellular events that culminates in the development of lung and other cancers (Hall 1994).
1 sty 1984 · The valence electrons are not bound as strongly as are those of the lighter Group VIII elements, and at high radon concentrations, the energy liberated by α decay facilitates compound formation. Radon reacts with fluorine gas at 400°C to form a stable, nonvolatile fluorine compound.
14 gru 2020 · Research indicates the effect of radon on Langerhans cells, an increase in enkephalin levels and a reduction in the amount of free oxygen radicals in phagocytes [61]. Treatments using radon media increase the synthesis of adrenal cortex hormones, as well as female and male sex hormones.
1 sty 1990 · The radon atom possesses a stable closed shell electronic configuration which gives it the chemical properties of a noblegas element. It behaves as expected by comparison with the other inert gases in the periodic table including helium, neon, argon, krypton, and xenon.
