Answer the questions below each text by choosing A, B, C
11、 or D._A study by scientists in Finland has found that mobile phone radiation can cause changes in human cells that might affect the brain, the leader of the research team said. But Darius Leszczynski, who headed the 2-year study and will present findings next week at a conference in Quebec, said mo
12、re research was needed to determine the seriousness of the changes and their impact on the brain or the body. The study at Finland“s Radiation and Nuclear Safety Authority found that exposure to radiation from mobile phones can cause increased activity in hundreds of proteins in human cells grown in
13、 a laboratory, he said. “We know that there is some biological response. We can detect it, with our very sensitive approaches, but we do not know whether it can have any physiological effects on the human brain or human body“, Leszczynski said. Nonetheless the study, the initial findings of which we
14、re published last month in the scientific journal Differentiation, raises new questions about whether mobile phone radiation can weaker/the brain“s protective shield against harmful substances. The study focused on changes in cells that line blood vessels and on whether such changes could weaken the
15、 functioning of the blood-brain barrier, which prevents potentially harmful substances from entering the brain from the bloodstream, Leszczynski said. The study found that a protein called hsp27 linked to the functioning of the bloodbrain barrier showed increased activity due to irradiation and poin
16、ted to a possibility that such activity could make the shield more permeable, he said. “Increased protein activity might cause cells to shrinknot the blood vessels but the cells themselvesand then tiny gaps could appear between those cells through which some molecules could pass“, he said. Leszczyns
17、ki declined to speculate on what kind of health risks that could pose, but said a French study indicated that headache, fatigue and sleep disorders could result. “These are not life-threatening problems but can cause a lot of discomfort“, he said, adding that a Swedish group had also suggested a pos
18、sible link with Alzheimer“s disease. “Where the truth is I do not know“, he said. Leszczynski said that he, his wife and children use mobile phones, and he said that he did not think his study suggested any need for new restrictions on mobile phone use.(分数:10.00)(1).According to Leszczynski, how doe
