good,学校永久停止了那三项临床试验,scientists from elsewhere had claimed that Dr Potti had stolen their data for inclusion in his paper in the New England Journal,另有科学家称Potti士在其在新英格兰杂志发表的文章中窃取了他们的数据,and officials at Duke had started the process of retracting three prominent papers, including the one in Nature Medicine.杜克大学方面也开始撤回他那三篇出名的文章,《自然-医学》的那篇也包括在内。At this point, the NCI and officials at Duke asked the Institute of Medicine, a board of experts that advises the American government, to investigate.到了这时候,国家癌症研究所和杜克大学都请求负责向美国政府提出建议的美国医学协会对此事进行调查。Since then, a committee of the institute, appointed for the task, has been trying to find out what was happening at Duke that allowed the problems to continue undetected for so long,之后,协会的一个专为此事成立的委员会就一直在努力查清是什么使得杜克大学长时间对问题不管不问,and to recommend minimum standards that must be met before this sort of work can be used to guide clinical trials in the future.并建议在今后碰到此类可供指导临床试验的研究时,需要其达到一个最低标准。At the committees first meeting, in December 2010, Dr McShane stunned observers by revealing her previously unpublished investigation of the Duke work.在2010年12月举行的该委员会的第一次会议上,McShane士披露了此前未发表的她关于杜克大学事件的调查,Subsequently, the committees members interviewed Dr Baggerly about the problems he had encountered trying to sort the data.这些材料震撼了在场的学者。结果,委员会的成员询问了Baggerly士关于他在尝试整理那些数据时遇到的问题。He noted that in addition to a lack of unfettered access to the computer code and consistent raw data on which the work was based,他指出,那些急于出版Potti士的论文的杂志不仅没有获得研究结果所涉及的计算机程序代码和可信的原始数据,journals that had ily published Dr Pottis papers were reluctant to publish his letters critical of the work.甚至还不情愿刊登他对于该成果质疑的文章。Nature Medicine published one letter, with a rebuttal from the team at Duke, but rejected further comments when problems continued.《自然-医学》杂志刊登了一篇文章,并附上了来自杜克大学研究组的辩驳,可是当问题继续存在时就拒绝了进一步的。Other journals that had carried subsequent high-profile papers from Dr Potti behaved in similar ways.其他刊载了来自Potti士的高曝光文章的杂志也采取了相似的态度。Eventually, the two researchers resorted to publishing their criticisms in a statistical journal, which would be unlikely to reach the same audience as a medical journal.最后,两位研究员只好把他们的文章发到了一个统计杂志,这就很难被医学杂志的读者群看到了。Two s ubsequent sessions of the committee have included Dukes point of view.委员会接下来的两次会议都包含了杜克方面的观点。At one of these, in March 2011, Dr Nevins admitted that some of the data in the papers had been “corrupted”.在2011年3月的一次会议中,Nevins士承认文章中的一些数据被“玷污”了。He continued, though, to claim ignorance of the problems identified by Dr Baggerly and Dr Coombes until the Rhodes scandal broke,但他声称直到Rhodes丑闻被揭发才得知Baggerly士和Coombes士指出的问题,and to support the overall methods used in the papers—though he could not explain why he had not detected the problems even when alerted to anomalies.而且虽然他没法解释为什么他没能在被指出异常时发现问题,但是他仍然在总体上持文章中采用的方法。At its fourth, and most recent meeting, on August 22nd, the committee questioned eight scientists and administrators from Duke.在第四次,也就是在8月22号举行的最近一次会议上,委员会质问了8位科学家和杜克大学的管理人员。Rob Califf, a vice-chancellor in charge of clinical research, asserted that what had happened was a case of the “Swiss-cheese effect” in which 15 different things had to go awry to let the problems slip through unheeded.Rob Califf, 一位负责临床研究的的副校长,称该事件是一个“瑞士奶酪效应”的例子,它需要15件不同的事都出了错才有可能让问题不被察觉。Asked by The Economist to comment on what was happening,当被《经济学人》的记者问到他关于这件事的评价时,he said, “As we evaluated the issues, we had the chance to review our systems and we believe we have identified, and are implementing, an improved approach.”他说“对这些问题的评估,使得我们有机会重新审视我们的体系,而且我们相信我们已经确认并且在采取改进后的方式了。”The universitys lapses and errors included being slow to deal with potential financial conflicts of interest declared by Dr Potti,校方的过失和错误包括在处理潜在利益冲突时反应迟缓。Dr Nevins and other investigators, including involvement in Expression Analysis Inc and CancerGuide DX, two firms to which the university also had ties.这些冲突方包括Potti士和Nevins士,其他的调查者,还有两家与大学有关系的公司Expression Analysis和CancerGuide DX。Moreover, Dr Califf and other senior administrators acknowledged that once questions arose about the work, they gave too much weight to Dr Nevins and his judgment.除此之外,Califf士和其他高级管理者承认,当出现有关于研究成果的质疑时,他们过分地看重了Nevins士和他的判断。That led them, for example, to withhold Dr Baggerlys criticisms from the external-review committee in .这导致了年他们把Baggerly士的挡在外部评审委员会之外。They also noted that the internal committees responsible for protecting patients and overseeing clinical trials lacked the expertise to review the complex, statistics-heavy methods and data produced by experiments involving gene expression.他们还提到了,负责保护病人和监督临床试验的内部委员会缺乏专业知识来评审由涉及基因表达的实验产生的复杂、侧重统计的方法和数据。That is a theme the investigating committee has heard repeatedly.这是一个调查委员会反复听到的说法。The process of peer review relies on the goodwill of workers in the field, who have jobs of their own and frequently cannot spend the time needed to check other peoples papers in a suitably thorough manner.同行审查制度依靠着内行人的善意,大家都有自己的工作,所以常常不能花足够的时间来对其他人的论文进行恰当细致的检查。Moreover, the methods sections of papers are supposed to provide enough information for others to replicate an experiment, but often do not.而且,文章的介绍实验方法的部分本应该为其他人提供重现实验结果所需的信息,但事实经常不是这样。Dodgy work will out eventually, as it is found not to fit in with other, more reliable discoveries.掺假的研究结果最终会被淘汰,因为它们不能与其他更加可靠的发现相兼容。But that all takes time and money.但是,这些都需要时间和金钱。The Institute of Medicine expects to complete its report, and its recommendations, in the middle of next year.美国医学协会计划在明年年中完成这个报告和相关的建议。In the meantime, more retractions are coming, according to Dr Califf.在此期间,据Califf士说将会有更多论文撤回。The results of a misconduct investigation are expected in the next few months and legal suits from patients who believe they were recruited into clinical trials under false pretences will probably follow.关于此次学术不端的的调查结果预计将在未来几个月内获得,而认为自己被欺诈进入临床试验的病人则可能会在之后提起诉讼。The whole thing, then, is a mess.整件事就是一团糟。Who will carry the can remains to be seen.谁将会承担责任目前还不清楚。But the episode does serve as a timely reminder of one thing that is sometimes forgotten.但是这一连串事件的确及时地提醒了我们一件常常被忽略的事实:Scientists are human, too.科学家也是人。 /201305/242083本溪市人民医院治疗宫颈糜烂多少钱

本溪妇幼保健院网上预约电话A camel can travel hundreds of miles, over several days, without stopping to drink.骆驼可以行走数百英里,并在几天之内也不用喝水。On todays Moment of Science, well learn how camels survive the dry desert.在今天的科学一刻中,我们将会学习骆驼是怎样在干燥的沙漠中生存的。Lets start with the hump.我们先从驼峰说起,Contrary to what you might have heard, camels do not store extrawater here.和你所听说的不一样的是,骆驼并没有储存多余的水在这里。The hump stores fat, providing energy for their long, desert trek.驼峰积聚着脂肪,为它们长距离的沙漠旅行提供能量。This fat, however,can help keep a camel from getting thirsty.然而就是这些脂肪,可以帮助骆驼止渴。As the fat is burned, water is produced as one of thebyproducts.水就是这些脂肪燃烧所产生的副产物之一。This extra water enters the camels bloodstream to add to its water supply.这些额外的水进入骆驼的血液,增加其水分的供应。Camels conserve water by not sweating as much as we do.骆驼不像我们那样出汗,这样也可以储存水分。A camels metabolism lowers at night,making its body temperature much lower than a humans.骆驼的新陈代谢到晚上就会降低,让它的体温低于人类。Because we sweat to cool ourselves off,starting with a lower body temperature means less need to sweat.出汗可以冷却我们自己,因此如果体温较低的话,对汗水的需求也会比较少。Camels are also covered withheavy fur which keeps the daytime heat out.骆驼同样覆盖着厚重的皮毛,这些皮毛可以防止白天的热量进入体内。Because its so good at keeping its cool, a camel cantravel a long way without sweating very much.正因为骆驼如此擅长保持其身体的冷却,所以它可以走很长时间,却不会流很多汗。Camels are also good at maintaining their blood volume.骆驼同样也很擅长保持它们的血容量。Once we humans lose about twelvepercent of our bodys water, our blood becomes too thick to work properly.我们人类一旦流失了身体百分之十二的水分,血液就会变得太浓稠以至于不能正常工作。A camels blood,however, stays more or less consistent, allowing the camel to lose up to twenty-five percent of itsweight by dehydration.可是骆驼的血液,总是可以坚持到让其脱水到其重量的百分之二十五。Another thing that helps a camel conserve water is its nasal passages.另一个有助于骆驼储存水的东西就是鼻腔。When we exhale, we loosea lot of water vapor, as any fogged up car window will prove.当我们呼气的时候,我们会流失许多水蒸汽,被雾气模糊的车窗可以明这一点。Camels have extra dry nasalpassages which actually recondense the water out of each breath, allowing much less to escape.骆驼有额外的干燥鼻腔,可以凝聚每次呼吸的水分,让水分的蒸发的变少。As you can see, there is no single explanation for a camels desert survival abilities.就如你所见,没有关于骆驼沙漠生存能力的单一解释。Instead, a cameldraws on a whole range of adaptations.相反地,骆驼有一系列的适应能力。 /201408/323661辽宁省本溪市人民医院是不是有主任 Books and Arts; Book Review; New fiction from Japan;文艺;书评;来自日本的新小说;Hey babe, take a walk on the wild side;嗨,去野外散个步吧;A black cat, two moons and a host of nocturnal little people populate Haruki Murakamis new novel. But has he become more conventional?在村上春树的新书里,他将一只黑猫、两轮月亮以及一群夜晚小小人拟人化。但他是否变得更保守点了呢?Haruki Murakami filches from George Orwells “Nineteen Eighty-Four” for the title of his new novel, “1Q84”, making a play on kyu, the Japanese word for nine, by transposing the letter “Q” for the number “9”. Significantly, the action also takes place over the last nine months of 1984. But it would be a mistake to conclude from this that Japans magical postmodernist has spent nearly 1,000 pages writing about a dystopian world where couples make love in an ash glade, hardly daring to speak because of the all-listening microphones in the trees. Mr Murakamis main influence here is not so much Orwell as Philip Pullman; his “1Q84” less a stairway to another world than a heave-ho into a whole new universe.村上春树的新书《1Q84》书名的灵感来自于对乔治·奥威尔( George Orwell)《1984》一书的借鉴(他把“9”改成了“Q;,而在日语里,“9”的发音与Q谐音)。此外,值得注意的是,书里故事发生的时间也是1984年最后的9个月。因此,如果错误地认为这位日本后现代魔幻大师花了近1000页的笔墨,只为描写一个情侣在野外做爱,并由于树上装有所有人都能听到的窃听器而不敢发出丝毫声音的反乌托邦世界,这就错了。但是村上春树在这里的主要影响并不像奥威尔或是菲利普·普尔曼(Philip Pullman)一样,他的《1Q84》一书与其说是通往另一个世界的阶梯,还不如说是完全逃向一个全新的世界。Sitting in a taxi on the gridlocked elevated Metropolitan Expressway in Tokyo, Aomame, the skinny heroine with asymmetric breasts (her name means “green peas”), is catapulted into action when she hears Janaceks “Sinfonietta” on the radio. Her cabbie tells her she can beat the traffic by hopping out of the car and down an emergency staircase at the next exit. He warns her that things will not be the same. But it is only when Aomame notices that the policemen have swapped their holstered revolvers for bulky semi-automatic weapons that she realises she has entered a parallel universe.当身材纤瘦、两个乳房不对称的女主角青豆(Aomame,其意为“绿色的豆子”)坐在一辆出租车里,在堵得水泄不通的东京高速公路上蹒跚前行时,车里广播放着亚纳切克(Aomame)的小交响曲,此时此刻,故事开始了。出租车司机告诉青豆说她可以通过走一条附近出口的紧急通道来绕开堵车,不过,他警告说如果她这么做了,事情将会不一样了。但当青豆注意到警察们的左轮手变成了笨重半自动手时,才意识到自己进入了一个平行宇宙。This gripping beginning ensures the er falls for Aomame, forcing Mr Murakami to work extra hard on her counterpart, Tengo, who appears in alternate chapters in the book. Tengo is an unpublished novelist who keeps to himself, working as a private maths tutor in a prep school. His father was a debt-collector who rounded up licence fees for the NHK television network, dragging his son along with him on Sundays as he called on households door-to-door. Tengos beloved mother died when he was very young, and the boys earliest memory is of hearing his mother having her breasts sucked by a man who was not his father. Tengos flat-pack character fills out as the book evolves, in particular in a long passage when he visits his aged father in his nursing home and tries to talk to him about the past.这一引人入胜的开头保了读者会为青豆而倾倒,这迫使村上春树得花更大的力气去塑造他的另一个人物——天吾(Tengo),在书里,天吾的故事与青豆的故事平行进行。天吾在一所补习学校里担任数学老师,他是个孤僻的业余写手,但他的小说从没发表过。天吾的父亲是NHK公司负责上门收费的收款员,周日的时候会拉着儿子跟他一起到各家各户去收电视有线费。天吾挚爱的母亲在他很小的时候就去世了,而他最早的回忆则是听着一个不是他父亲的男人在吮吸他母亲的乳房。随着小说情节的进展,天吾原本单薄的形象逐渐丰满起来,其中有一大段他的形象特别突出,这一段描写了他去养老院探望年老的父亲,并试图与父亲谈论过去。Tengos life changes when a friend, a grumpy editor named Komatsu, persuades him to clean up a raw manuscript by a teenage girl, Eriko Fukada, called Fuka-Eri throughout. Komatsu believes that the girls autobiographical story, about being raised on a rural commune that changes into a sinister cult involved in mind games and child abuse, has all the makings of a bestseller if its style can be improved enough so that it wins a literary prize. Aomame, as might be expected from a woman who shimmies down from an overhead expressway without much concern for her stockings or her chestnut- coloured Charles Jourdan heels, turns out to be a minx on the make, a charming, ball-breaking, feminist do-gooder who likes nothing better than rounding off a days killing with an all-night bout of bisexual sex. Aomame is really a hired gun, who specialises in quietly offing wife-beaters and child rapists, a manga version of Stieg Larssons Lisbeth Salander.当天吾的朋友——性子暴躁的编辑小松(Komatsu)劝他去修改少女深田绘里子(Eriko Fukada)(文中一直叫做深绘里)小说的初稿时,天吾的生活发生了变化。深绘里这部自传体的小说描写了自己生长的村庄公社被转变成了一个邪恶的新兴宗教团,充满勾心斗角和虐待儿童。小松认为如果小说风格能得到很好修改的话,使其拿下一座文学奖,那就足以让它成为畅销书了。青豆,人们原来也许以为她是一个不顾自己还穿着丝袜和褐色佐丹高跟鞋摇摇晃晃地翻过高空中的公路的女子,事实上却是一个野心勃勃的狐狸精,一个迷人而强势的女权主义者,一个妄图替天行道者,最喜欢每天出去干净利落地杀人,然后晚上来场疯狂的通宵性爱,男女不限。青豆实际上是个职业杀手,精于无声无息地除掉那些虐待妻子或侵犯儿童的男人,简直就是史迪克·拉尔森(Stieg Larsson)笔下丽丝贝·莎兰德(Lisbeth Salander)的日本漫画版。Aomames and Tengos parallel stories begin to rub against one another long before the characters do. They both see a black cat and two moons (one shiny and normal, the other misshapen and moss-coloured); and both know about the little people who emerge periodically from the mouth of a sleeping child and disappear under the childs bed. The two heroes were once at school together and even, briefly, held hands at the age of ten. An unresolved longing to recapture that moment permeates both their lives, and the will-they-wont-they question overshadows the whole book.早在两位主角在这个反乌托邦世界里相遇之前,青豆和天吾这两条平行的故事线就开始交织在一起了。他们都看见了一只黑猫和两轮月亮(一轮形状正常,散发着光芒,另一轮却形状诡异,而且是苔藓一般的颜色);他们也都知道小小人:那些小小人会不时从睡着的小孩口中爬出来,消失在床底下。 两位主角是校友,而且,他们在十岁的时候还有过一次牵手。想要重新拾回那个瞬间的渴望无法满足,渗入了他们两人的生活,而全书充斥着他们最终能在一起吗这个问题。Herein lies the conundrum of “1Q84”. Mr Murakamis reputation as Japans greatest literary surrealist is based on a series of short stories and novels, such as “Hard-boiled Wonderland and the End of the World”, which came out in 1985, and “Norwegian Wood” two years later. His early works were intensely personal fantasies involving unhappy, virtually disembodied men and suffused with references to Western music and literature. “1Q84” is much longer, but also far more conventional.这里有个关于“1Q84”的谜题。村上春树因一系列超现实主义的短文和小小说而被誉为日本最伟大的文学大师,这些文章包括1985年出版的《世界尽头与冷酷仙境》以及1987年出版的《挪威的森林》等。他早期的作品集中于描写郁闷的游魂般的男人的个人幻想,充斥各种西方音乐和文学的参考资料。相比之下,《1Q84》篇幅要长得多,但也保守得多。Like two American writers, Jonathan Franzen and Jeffrey Eugenides, both known for their fizzy inventiveness but whose recent work is more plot-driven, Mr Murakami seems to have made a conscious move towards romantic narrative. Mr Franzens latest book asks whether the married protagonists will stay together; Mr Eugenidess which of the two main heroes will his heroine end up with (if any). It is Mr Murakamis turn, now, to cut in on the boy-girl gavotte. This has certainly proved a popular move. When the first two volumes of “1Q84” were published in Japanese in , more than 1m copies were sold in just a few weeks; the third volume followed to similar acclaim a few months later. Keeping up originality can be hard work. But Mr Murakamis new direction, like that of Mr Franzen and Mr Eugenides, is bringing him thousands of fresh ers. And that is a good thing.和两位均因创造性而闻名(但他们现在的作品更加注重阴谋)的两位美国作家乔纳森·弗兰岑(Jonathan Franzen)和杰弗里·尤金尼德斯(Jeffrey Eugenides)一样,村上春树似乎也有意描写男女之间的爱情故事。弗兰兹的新书怀疑已婚的主角们是否还会在一起;尤金尼德斯则抛出了女主角会跟两位主要男主角中的哪位在一起(如果她要跟一个人在一起的话)的问题。现在,轮到村上春树来决定男女主角之间的关系了,这显然是最近的流行趋势。年当《1Q84》的前两卷在日本出版时,几周之内就卖出了100多万本;几个月之后,第三卷也卖出了同样数目。追求原创性绝非易事,但是就如弗兰兹和尤金尼德斯一样,村上春树的新方向为他带来了成千上万的新读者。 这是件好事。 /201304/236016明山区北地河东新明街道医院网上预约
