long-term treatment outcomes of 232 patients who had used NSAIDs regularly before treatment with the outcomes of the 974 men with no history of regular NSAID use. Other characteristics, such as smoking, were balanced between the two groups. The fol...
Good news: As you age, leg blood vessels adapt so you can still exercise without fainting

Low dose radiation evades cancer cells' protective 'radar'
... colon cancer cells survived low-dose radiation as compared
to 60 percent receiving high-dose. In prostate cancer cell lines, half of the cells survived low-dose radiation, while 65 percent remained in higher doses. In the low-dose group, ATM activation was reduced by 40 to 50 percent. The researchers proved ...

Why do African-American women have more pregnancy problems?

Rutgers-led research offers new clues in the genetic mysteries of maize

to closely related species today, the researchers found that as much as 22 percent of the maize genes could be identified as being different. This was surprising, considering that other close relatives such as chimpanzees and humans differ in less ...
