A new stud

35、y suggests that calorie restriction can help slow the normal process of cell death that happens with age. Researchers say the body naturally goes through a process known as apoptosis, or cell death, to destroy old cells so new ones can be made, and many factors can alter this process. Age-related di

36、seases, such as Alzheimers and Parkinsons, cause a higher-than-normal loss of cells in the brain, which can lead to loss of function. Previous studies have suggested that calorie restriction can boost life span and mental capacity. That prompted researchers to look at whether cutting calories might

37、also play a role in protecting aging brain cells. They compared levels of proteins indicating brain cell death in two groups of rats. One group was given unrestricted access to food and water throughout their lives. The other was given 40% fewer calories (but still adequate nourishment) than the unr

38、estricted group. They found that the levels of these proteins increased with normal aging in the rats fed unrestricted diets. The rats given a restricted diet did not have an increase in the levels of these proteins. Another protein thought to protect from cell death dropped by 60% in the well-fed r

39、ats, but it actually increased over time in the calorie-restricted rats. Finally, DNA fragmentation, a third indicator of cell death, more than doubled in the unrestricted rats with age, but this increase was 36% less in the calorie-restricted rats. Although the results are promising, researchers sa

40、y more study is needed to completely understand the processes that lead to cell death and the role nutrition plays in that process. Meanwhile, they say, their study provides yet another reason to watch what you eat. “Were not going to do it right away to improve our memories; were going to do it pro

41、bably in general for the first reasons, which would be to prevent cardiovascular disease and cancer,“ says Christian Leeuwenburgh at the University of Florida. 81 The main purpose of these researchers is _ （ A） to help to destroy old cells and boost new ones （ B） to alter the natural process known a

42、s apoptosis （ C） to find out ways to protect aging brain cells （ D） to compare different levels of proteins 82 The rats fed unrestricted diets do NOT _ （ A） have one preventing-aging protein increased （ B） have their cell death increased or doubled （ C） have their DNA fragmentation doubled （ D） have

43、 the levels of proteins increased 83 The result of the researches so far may help, as asserted by one of the researchers, _ （ A） to prevent cardiovascular disease and cancer （ B） to understand the processes that lead to cell death （ C） to improve our memories （ D） to do what we think is right 84 Whi

44、ch of the following statements is true, according to the passage? （ A） Scientists make no progress in the researches. （ B） Researchers have made a great breakthrough. （ C） More researches are to be made in the field. （ D） The more proteins the less calories the better. 85 What kind of benefits has b

According to the study, Amazon. com is the premier e-commerce company, having translated its Brand Performance into value on the Clicks Interaction.
