Original Source: Morin (2',3,4',5,7-Pentahydroxyflavone) Protected Cells against gamma-Radiation-Induced Oxidative Stress.
Ionizing radiation can induce cell damage by generating reactive oxygen species (ROS). The present study was carried out to investigate the radio-protective effects of a flavonoid compound, morin (2',3,4',5,7-pentahydroxyflavone) and the underlying mechanisms. Morin was found to reduce the intracellular ROS generated by gamma-irradiation. Moreover, morin protected cellular components against radiation-induced membrane lipid peroxidation and cellular DNA damage, which are the main targets of radiation-induce...

Scientists have known for almost a decade that thunderstorms are capable of generating brief but powerful bursts of gamma-rays called terrestrial gamma-ray flashes, or TGFs. Because they can originate...
[News] Natural gamma radiation and childhood leukaemia
An increased risk for childhood leukaemia has been shown to be associated with gamma radiation from natural sources. A recent study examined background radiation exposure in 27 447 patients with ch...
Natural exposure to gamma rays in background radiation linked to childhood leukemia
New findings demonstrate that there are small effects of radiation even at very low doses.
Gamma rays in background radiation linked to childhood leukaemia
(Medical Xpress) -- A small but statistically significant link between risk of childhood leukaemia and the gamma rays we are all exposed to from our natural environment has been detected in a very lar...
gamma-Secretase lost and sound
Japanese and U.S. researchers have shown that inhibiting gamma-secretase in the middle ear can promote hair cell regeneration and recovery from deafness in rodents. Keeping potentially toxic gamma-sec...
Creation of gamma optics refutes physics assumption
In experiments with gamma rays in France, researchers have recently proven that these extremely high-energy electromagnetic waves can be focused by lenses like conventional light. This finding that...
Astronomers find pulsar with a tremendous hiccup
Using data analysis methods, an international collaboration of researchers dug an unusual gamma-ray pulsar out of imagery from the Fermi Gamma-ray Space Telescope. The pulsar they found is radio-qu...

Radioprotection by alpha-Lipoic Acid Palladium Complex Formulation (POLY-MVA) in Mice.
Abstract The dietary supplement, POLY-MVA, containing palladium alpha-lipoic acid complex was examined for its efficacy as a radioprotector in mice exposed to whole-body gamma-radiation. Oral administ...
The radioprotective effect of geraniin, a tannin compound isolated from Nymphaea tetragona Georgi var. (Nymphaeaceae), against gamma-radiation-induced damage was investigated in Chinese hamster lung f...
Abstract Recent studies have suggested that visualization of gamma-H2AX nuclear foci can be used to estimate exposure to very low doses of ionizing radiation. Although this approach is widely used for...
