[单项选择]Stem Cell Therapy May Help Repair the Heart
According to scientists in the USA，stem cell therapy may one day be able to repair the hearts of people with heart failure．Researchers at Pittsburgh University School of Medicine examined 20 patients who had severe heart failure and were going to have surgery．
They injected stem cells into the parts of their hearts that were damaged，They then compared their hearts with those of people who had undergone surgery without having the stem cells injected into them(they had also suffered from severe heart failure)．The patients who had had the stem cells injected had hearts that were able to pump(用泵抽运)more blood than the others．
According to Professor Robert Kormos，one of t11e researchers，these results could revolutionize heart treatment．Although previous studies had indicated that there might be a benefit，this is the first study that has actually proved that stem cell therapy can help the failing heart work better．

[简答题]Cell phones may help busy executives keep in constant touch with important business associates, but they may also increase their risk of high blood pressure, preliminary research suggests. A study of 10 German mobile phone users found that when they switched on their phone, their blood pressure shot up by 5 to 10 millimeters of mercury, researchers reported in this week’s issue of the international medical journal, The Lancet. Exactly how cell-phone use can lead to increases in blood pressure is unclear, but researchers speculate that the electromagnetic fields emitted by phones may somehow boost pressure. While the blood pressure increases found in the new study are small, they may be detrimental to people who already suffer from hypertension, researchers led by S. Braune of the Neurologische Universitateklinik in Freiburg, Germany, explained.

[单项选择]Motherhood may make women smarter and may help prevent dementia in old age by bathing the brain in protective hormones, US reseachers reported on Thursday.
Tests on rats show that those who raise two or more litters of pups do considerably better in tests of memory and skills than rats who have no babies, and their brains show changes that suggest they may be protected against diseases such as Alzheimer’s. University of Richmond psychology professor Craig Kinsley believes his findings will translate into humans.
"Our research shows that the hormones of pregnancy are protecting the brain, including estrogen, which we know has many neuroprotective effects, " Kinsley said.
"It’s rat data but humans are mammals just like these animals are mammals, " he added in a telephone interview. "They go through pregnancy and hormonal changes. "
Kinsley said he hoped public health officials and researchers will look to see if having had children protects a woman from Alzheimer’s an
