Journal ArticleDOI
Low-Dose Radiation Exposure and Atherosclerosis in ApoE−/− Mice
R. E. J. Mitchel,M. Hasu,Michelle Bugden,Heather Wyatt,Mark P. Little,A. Gola,Guido Hildebrandt,Nick Priest,Stewart C. Whitman +8 more
TL;DR: Low doses given at low dose rate during either early- or late-stage disease were protective, slowing the progression of the disease by one or more of these measures, suggesting that low doses may influence this disease by more than one mechanism and that dose rate is an important parameter.
Journal ArticleDOI
Low-Dose Radiation Exposure and Protection Against Atherosclerosis in ApoE–/– Mice: The Influence of P53 Heterozygosity
R. E. J. Mitchel,M. Hasu,Michelle Bugden,Heather Wyatt,Guido Hildebrandt,Yong-Xiang Chen,Nick Priest,Stewart C. Whitman +7 more
TL;DR: The results indicate that variations in p53 functionality can dramatically alter the outcome of a low-dose exposure, and that the assumption of a linear response with dose for human populations is probably unwarranted.
Journal ArticleDOI
Metabolism of 210Po in rats: volatile 210Po in excreta.
Chunsheng Li,Baki Sadi,Heather Wyatt,Michelle Bugden,Nicholas Derham Priest,Diana Wilkinson,Gary H. Kramer +6 more
TL;DR: Results showed that the daily excretion of volatile (210)Po by the rats is in a very small percentage (0.002-0.009 %) of the administered amounts, however, if the administered amount is large, the excreta can be significant.
Journal ArticleDOI
Biokinetics of 210Po in rats: excretion via urine and faeces and retention in tissues and organs
Chunsheng Li,Baki Sadi,Heather Wyatt,Michelle Bugden,Nick Priest,Diana Wilkinson,Gary H. Kramer +6 more
TL;DR: Daily excretions of ²¹⁰Po from rats via urine and faeces following i.v. administration of polonium citrate, from Day 2 to Day 5, were reported, together with retentions in tissues and organs on Day 5.
Journal ArticleDOI
Metabolism of 210Po in rats: volatile 210Po from faeces.
TL;DR: The metabolic formation of volatile (210)Po species in a rat that was intravenously administered with ( 210)Po-citrate was investigated and indicates that the metabolic formation is likely to occur in the gut due to bacterial activity.
