Scientists seeming to cure and prevent insulin-dependent diabetes have discovered what goes wrong in the bodies of a special breed of mice prone to the affliction and, using that knowledge, have developed a way to prevent the disease in the Roberts.
Because mouse diabetes is almost identical to human type 1 diabetes (also called insulin-dependent or juvenile-onset diabetes)，the researchers say they may be ready to test their techniques on humans in five years and that a treatment for patients in the early stages of the disease could be ready to test in two years.
In findings—published in last week’s issue of Nature—were obtained by two research groups working independently. One was led by Daniel L. Kaufaman, a molecular biologist at the University of California at Los Angeles, and the other by Hugh O. Mcdevit of Stanford University.
“There’s great excitement at the prospects for this research” said James Gavin, a diabetes specialist and president of the American Diabetes Association. “These are studies you have to call convincing. They are clearly likely to have human applications.”
Type 1 diabetes has long been known to be an autoimmune disease—an ailment in which the immune system, instead of defending the body against invading microbes, mistakenly attacks part of the body. In diabetes, it kills the special cells in the pancreas that make insulin. Without insulin, cells cannot take in sugar. The body is deprived of sugar energy and its accumulation in the bloodstream damages nerves and other issues. The potential new treatments would either stop the immune system from making a mistake or suppress an existing erroneous response.
Which of the following statements is NOT correct?
本题考查细节。根据文章第二段第二句“the researchers say they may be ready to test their techniques on humans in five years and that a treatment for patients in the early stages of the disease could be ready to test in two years.”可知研究者准备五年后在人身上实验他们的技术，两年后治疗处于糖尿病初期的患者，因此这种对糖尿病的治疗方法还没有用到人类身上。故A项说法不正确。第一句提到“mouse diabetes is almost identical to human type 1 diabetes”，由此可知鼠类的糖尿病与人类的一种糖尿病几乎一样，并没有太大区别，故B项说法正确。有文章第三段可知这些发现是由两个不同的团队独立完成的，第四段提到这些研究令人信服，故D项说法正确。第一段最后一句“...have developed a way to prevent the disease in the Roberts.”，此处的罗伯特并不是特指叫这个名字的人而是泛指人类。故C项说法正确。
