问题     延缓衰老进程的药物
    这听起来有点像科幻影片,但可延缓衰老进程的药物有望变为现实。
    俄罗斯的科学家正在试验一种新配方,他们宣称该配方可以延缓衰老进程。他们希望这种正在老鼠、小鼠、鱼以及狗身上试验的药片能够将人类的寿命至少延长到120岁。莫斯科国立大学项目的研究员马克西姆-斯古拉乔夫(Maxim Skulachev)博士称:“大量的衰老病症进展更为缓慢。”科学家正在使用一种“新型抗氧化剂”,他们希望会影响线粒体,线粒体是细胞中的能量产生部分,被认为会引发人体老化。
    斯古拉乔夫说:“线粒体会引发心脏发作,也与阿尔兹海默症和帕金森氏综合症等疾病有关。”他指出东非的鼹鼠以长寿和明显对癌症免疫而闻名。他表示,现实的目标是将人类的寿命延长到120岁,抗衰老药物“在技术上是可行的”。“我不相信我们能活到800岁的高龄。”“但很可能的是出现一些新疾病。比如说,120岁老人的典型病——癌症。以前人们的寿命较短时,很少有人患有这种病。”
    他说,他们的试验在延长寿命上还未取得突破性进展,但已经推迟了衰老的开始。“如果证明疾病发展的更为缓慢,我们通过线粒体抗击衰老的想法就是正确的。”斯古拉乔夫补充道。他已经在完善抗衰老试验上研究了数十年。

选项

答案 A Pill That Slows Down the Aging Process It sounds like something from a science fiction film, but a pill to counter the aging process could become a reality (a pill that slows down the aging process is expected to become a fact). Scientists in Russia are testing a new formula (are experimenting with a new drug), which they claim can delay/ postpone the start/ onset of the aging process. They hope the tablet/ pill, which is being tested on rats, mice, fish and dogs, will allow people to live to at least 120. Researcher Dr. Maxim Skulachev, from the Moscow State University project, said: " A lot of aging diseases developed much slower/ at a much slower rate. " The scientists are using a " new type of antioxidant" , which they hope will impact on the mitochondria, the energy-producing part of cells, which is seen as triggering aging (is believed to set off senility). "The mitochondria," he added, "can cause heart attacks, and diseases like Alzheimer’s, and Parkinson’s". He pointed to the mole-rat of east Africa renowned for longevity and evidently immune to cancer. He also said that a realistic goal was to aim for a life span for humans of 120, and anti-aging medication (an anti-senility drug) was ’technically possible’. "I don’t believe we will be able to live to 800," he said. "Most probably, some new disease will emerge, let’s say, a typical disease for a 120-year-old. That was the case with cancer, which was a rare disease when ancient people died much younger. " The Russian tests have not led to a significant life span increase, but delayed the onset of aging, he said. " If it turns out that diseases develop more slowly, our idea to fight aging through mitochondria is the right one", added Dr. Skulachev, who has been working to perfect his treatment for decades.
