共用题干Napping to a Healthier Heart?1 Researchers say they have developed a simple test that can tell if a person with heart disease is likely to suffer a heart attack.The test measures levels of a protein in the blood.The researchers say people with high levels of this protein are at high risk of heart attack,heart failure or stroke.2 Kirsten Bibbins-Domingo of the University of California in San Francisco led the team.For about four years,they studied almost one thousand patients with heart disease.The researchers tested the heart disease patients for a protein called NT-proBNP. Patients with the highest levels were nearly eight times more likely than those with the lowest levels to have a heart attack,heart failure or stroke.3 The researchers say the presence of high levels of the protein in the blood shows that the heart muscle is under pressure in some way.The study involved mostly men,so the researchers could not say for sure that the results are also true for women.They say the patients with the highest levels of NT-proBNP were older and had other problems like diabetes or high blood pressure.4 Other researchers say more studies are needed to confirm if knowing the protein levels of a heartdisease patient should affect that person’s treatment.They also would like to know if more aggressive treatment could reduce the patient's chance of a heart attack or stroke.The study appeared in theJournal of the American Medical Association.5 Could a little sleep during the middle of the day reduce the risk of a heart attack?An unrelatedstudy earlier this month in the Archives of Internal Medicine suggests that the answer may be yes.In countries like the United States,afternoon naps are mostly for children. But they are common for adults in Mediterranean countries.And these countries generally have lower rates of heart disease.So scientists in theUnited States and Greece wondered if naps could play a part.Twenty-three thousand healthy adults took part in the study by Harvard University and the University of Athens.Those who took thirty-minute naps three times a week had a thirty-seven percent lower risk of death from heart problems than people who did not takenaps.6 The researchers say napping may improve heart health by reducing stress.They say the researchsuggests that naps are especially good for working men.But they say not enough female subjects died during the study to judge the benefits for women.If a person has a high level of NT-proBNP_________.A: where fewer pepole die from heart problemB:whether they have the risk of heart attack,heart failure or stroke C:would probably have lower rates of heart diseaseD:how to test a person's NT-proBNP level in the blood by himselfE:his heart muscle would be under pressure in some wayF:that napping is of great benefit to women too

共用题干第一篇Human Heart can Make New CellsSolving a longstanding（为时甚久的）mystery, scientists have found that the human heart continues togenerate new cardiac（心脏的）cells throughout the life span, although the rate of new cell production slows with age.The finding,published in the April 3rd issue of Science,could open a new path for the treatment of heart diseases such as heart failure and heart attack,experts say."We find that the beating cells in the heart, cardiomyocytes（心肌细胞）,are renewed," said lead researcher Dr. Jonas Frisen,a professor of stem cell research at the Karolinska Institute in Stockholm,Sweden."It has previously not been known whether we were limited to the cardiomyocytes we were born with or whether they could be renewed,"he said."The process of renewing these cells changes over time,"Frisen added. In a 20-year-old,about 1percent of cardiomyocytes are exchanged each year , but the turnover（更替）rate decreases with age to only 0.45 percent by age 75."If we can understand how the generation of new cardiomyocytes is regulated,it may be potentially possible to develop pharmaceuticals（药物）that promote this process to stimulate regeneration after , for example,a heart attack,"Frisen said.That could lead to treatment that helps restore damaged hearts."A lot of people suffer from chronic heart failure,."noted co-author Dr. Ratan Bhardwaj,also from the Karolinska Institute."Chronic heart failure arises from heart cells dying," he said."With this finding,scientists are opening the door to potential therapies（疗法）,to having ourselves heal ourselves,"Bhardwaj said."Maybe one could devise a pharmaceutical agent that would make heart cells make new and more cells to overcome the problem they are facing."But barriers remain.According to Bhardwaj,scientists do not yet know how to increase heart cell production to a rate that would replace cells faster than they are dying off,especially in older patients with heart failure.In addition,the number of new cells the heart produces was estimated using healthy hearts一 whether the rate of cell turnover in diseased hearts is the same remains unknown.The human heart stops producing cardiac cells ______.A:when a person becomes oldB:as soon as a person gets sickC:immediately after a person is bornD:once a person dies
