帮忙翻译一下。英译汉

A meager diet may give you health and long life,but it's not much fun——and it might not even be necessary.Wemay be able to hang on to most of that youthful vigor even if we don'tstart to diet until old age. Stephen Spindler and his colleagues from the Universitu of California at Riverside have found that some of an elderly mouse's live genes can be made to behave as they did when the mouse was young simply by limiting its food for four weeks.The genetic rejuvenation won't reverse other damage caused by time for the mouse,but could hlp its liver metabolize drugs or get rid of toxins. Spindler's team fed three mice a normal diet for their whole lives,and fed another three on half-rations.Three more mice were switched from the normal diet to half-feed for a month when they were 34 months old——equivalent to about 70 human years. The researchers checked the activity of 11,000 genes from the mouse livers,and found that 46 changed with age in the normally fed mice.The changes were assocaiated with things like inflammation and free radical production——probably bad news for mouse health.In the mice that had dieted all their lives,27 of those 46 genes continued to behave like young genes.But the most surprising finding was that the mice that only started dieting in old age also benefited from 70 per cent of rhese gene changes. "this is the first indication that these effects kick in pretty quickly,"says Huber Warner from the Narional Institute on Aging near Washington,D.C. No one yet knows if calorie restriction works in people as it does in mice,but Spindler is hopeful."there's attracting and tempting evidence out there that it will work,"he says. If it does work in people,there might be good reasons for rejuvenating the liver.As we get older,our bodies are less efficient at metabolizing drugs,for example.A brief period of tome of dieting,says Spindler,could be enough to make sure a drug is effective. But Spindler isn't sure the trade-off is wor th it."The mice get less disease,they live longer,but they're hungry,"he says."Even seeing what a diet does,it's still hard to go to a restaurant and say:'I can only eat half of that'" Spindler hopes we soon won't need to diet at all.His company,Life Span Genetics in California,is longking for drugs that have the effects of calorie restriction.

一个贫乏的饮食会使你健康长寿，但没有太多的乐趣——它可能甚至没有必要的。我们能挂在大多数的青春活力即使我们不会饮食到老。史蒂芬和他的同事从加利福尼亚universitu河畔发现，一些老年小鼠的基因可表现为他们当鼠标是年轻的限制其食物为四周。遗传复兴不会逆转造成其他损害的时间的鼠标，但它可以帮助肝脏代谢药物或除去毒素。他是球队三小鼠正常饮食，为他们的整个生活，和另一个三half-rations.three更美联储小鼠切换从正常饮食个月喂入时的34个月——相当于人类70岁左右。研究人员检查了活动的11000个基因的小鼠的肝脏，并发现46的变化与年龄在正常饲养的老鼠。这些变化assocaiated与炎症和自由基的生产——可能是坏消息，对老鼠的健康。在老鼠已经节食的所有他们的生命，27人的46个基因继续表现像年轻的基因。但是最令人吃惊的发现是，小鼠，才开始节食在旧时代也受益于70%的这些基因的变化。”这是第一次表明，这些影响踢的非常快，”胡贝尔说华纳从国家衰老研究所附近的华盛顿哥伦比亚特区还没有人知道如果热量限制在人作为它在老鼠，但他是乐观的。”有吸引和证据表明它能工作，”他说。如果它不工作的人，可能会有很好的理由使肝脏。随着我们年龄的增长，我们的身体是效率较低的代谢的药物，例如。一个短暂的时期我节食，说他，就足以确保有效药物。但他不确定权衡都比它。”小鼠得到较少的疾病，他们的寿命较长，但他们饿了，”他说。“即使看到什么饮食，仍然很难去餐厅说：“我只能吃一半，”他希望我们很快，不需要食物在所有。他的公司，寿命遗传学在加利福尼亚，是龙晶药物有影响的热量限制。
