“When these findings were stratified by race and gender, they found that white men were at the highest risk-they were 86 percent more likely to have CAC. There was no higher odds of CAC for black participants who exercised at this level, and while there was a similar trend for white women it was not statistically significant.”
“High levels of exercise over time may cause stress on the arteries leading to higher CAC,” said Rana, “however this plaque buildup may well be of the more stable kind, and thus less likely to rupture and causes heart attack, which was not evaluated in this study.”
Since neural excitability in the hippocampus is a key feature of seizures and epilepsy, they hypothesized that acutely increasing protein O-GlcNAcylation might dampen the pathological hyperexcitability associated with these brain disorders.
“Bayesian theory does not support using an expert’s opinion, even when expressed numerically, as a universal weight of evidence. Among different ways of presenting information, it has not been shown that LR is most appropriate.”
