主题：【讨论】奥运来了 悬赏翻译 New Test Makes Cheating With Drugs In Sports Easier To Detect

A new mass spectrometry test can help sports anti-drug doping officials to detect whether an athlete has used drugs that boost naturally occurring steroid levels. The test is more sensitive compared to previous alternatives, more capable of revealing specific suspicious chemical in the body, faster to perform, and could be run on standard drug-screening laboratory equipment.

One of the roles of the masculinising hormone testosterone is to increase muscle size and strength. Taking extra testosterone, or taking a chemical that the body can use to create extra testosterone, could therefore enhance an athlete's performance. For this reason taking it is banned by the World Anti-Doping Agency (WADA).
The exact level of testosterone varies considerably between different people, so simply measuring total testosterone in an athlete's urine can not show whether he or she has deliberately taken extra. There is, however, a second chemical in the body, epitestosterone, which is normally present in approximately equal proportions to testosterone. Comparing the ratio of testosterone to epitestosterone can then indicate whether testosterone or a precursor has been taken.
The problem is that it is not always easy to measure these two substances, particularly as they are only present in urine at very low concentrations.
A team of scientists the Sports Medicine Research and Testing Laboratory at the University of Utah have developed a test that makes use of liquid chromatography-tandem mass spectrometry. This method has incredibly high sensitivity (down to 1 ng/ml) and increases the power with which officials can search for both testosterone and epitestosterone within a sample.
"Our system means that we can determine the testosterone/epitestosterone ratio in a sample with greater confidence, and therefore be in a better position to spot doping violations without falsely accusing innocent athletes," says lead investigator Dr Jonathan Danaceau.
"Not only is the test more sensitive, it is also faster to perform," says colleague Scott Morrison.

我来翻译一句
"Not only is the test more sensitive, it is also faster to perform," says colleague Scott Morrison.
同僚莫里森斯科特说：“检测不仅灵敏，而且完成快”。

一个新的质谱分析测试可能帮助体育反对服用麻醉品的掺杂的官员查出运动员是否使用了促进自然发生的类固醇水平的药物。 测试是更加敏感的与早先选择比较，能够显露在身体的具体可疑化学制品，更加快速执行，并且可能跑在标准药物掩护实验室设备。

男子化的激素睾甾酮的角色的</dnt>One是增加肌肉大小和力量。 因此采取额外睾甾酮或者采取身体可能使用创造额外睾甾酮的化学制品，可能提高运动员的表现。 为此采取它由世界反对添加剂代办处(WADA)取缔。
睾甾酮的</dnt>The确切的水平相当地变化区别人民之间，在运动员的尿的那么测量的总睾甾酮不可能显示他或她是否额外故意地采取了。 有，然而，在身体， epitestosterone的第二种化学制品，通常是存在对睾甾酮的大约相等比例。 比较睾甾酮比率与epitestosterone可能然后表明睾甾酮或前体是否被采取了。

The问题是测量这两种物质总是不容易的，特别因为他们只是存在尿以非常低集中。
科学家</dnt>A队犹他大学的运动医学研究和测试实验室开发了利用液体色谱法纵排质谱分析的一个测试。 这个方法有难以置信地高敏感性(下来对1 ng/ml)和增量官员能搜寻在样品之内的睾甾酮和epitestosterone的力量。

"我们的系统意味着我们可以确定在一个样品的睾甾酮或epitestosterone比率有更加伟大的信心，并且在察觉掺杂的一个更好的位置侵害，无需错误指责无辜的运动员， “Danaceau说调查主任乔纳森博士。

"不仅是更加敏感的测试，它也是更加快速的执行， “Morrison说同事斯科特。

一种新的质谱检测可以帮助反兴奋剂的官员查出一个运动员是否用了（某些）药物来提高其自身的类固醇激素的制造水平。这种检测（方法）比以往的检测更灵敏，能够更容易的检测出体内的一些特定的可疑的化学物质，检测速度更快，并且能够在标准药物筛选实验室的设备上运行。

雄性激素－睾酮的作用之一就是增加肌肉的尺寸和力量。服用外来的睾酮，或者某种能促进机体合成额外睾酮的药物，可以提高运动员的表现成绩。因此世界反兴奋剂中心是禁止服用这类药物的。

睾酮在人体内的正常水平的个体差异是非常大的，所以仅仅靠检测运动员尿液中的睾酮的量是不能反映出他是否服用了额外的睾酮的。但是，人体内的另外一种化学物质－表睾酮，它与睾酮之间的比例差不多是一个定值。因此测定睾酮与表睾酮的比例，能够反映出（运动员）是否服用了睾酮或者它的前体药物。

The problem is that it is not always easy to measure these two substances, particularly as they are only present in urine at very low concentrations.

但是有一个问题是这两种物质通常不是很容易检测，（特别是）因为它们在尿液里面的浓度极低。一个来自犹他大学运动医学研究和检测实验室的科学家团队建立了一种用液质联用仪来检测这两种物质的方法。这种方法有非常高的灵敏度（低至1 ng/ml），并且增强了（反兴奋剂的）工作人员仅靠一个样品来检测睾酮和表睾酮的能力。

出乎意料啊
看来要提前结束了

“我们（建立）的这套方法使我们在测定睾酮/表睾酮比率时非常有信心，因此能更好地找出那些服用兴奋剂的不良行为，不会侮蔑一个无罪的运动员。”（兴奋剂）调查主任Jonathan Danaceau博士这样说道。
“不仅检测更加灵敏，而且也更快。”（他的）同僚Scott Morrison说道。
