嘉定区人民妇幼中心医院有无痛人流术吗浏河镇子宫肌瘤多少钱Its five minutes before your big job interview. As you wait in the outer office, your palms start sweating, your feet shuffle back and forth, and the butterflies in your stomach are fluttering double time. Butterflies in your stomach?离你那场关键的面试只有5分钟了。你在办公室外面等待着,你的手心开始冒汗,双腿来来回回拖着,胃里的蝴蝶颤抖得更厉害了。什么,你的胃里有蝴蝶?In the late 1940s, a pair of medical researchers came across an unusual patient a soldier with a permanent opening between his inner stomach and his skin. The researchers used this opening as a window on the patients stomach physiology. If the patient was put in a stressful situation, the researchers discovered a sudden decrease in the amount of acid that the stomach produced. They also discovered a decrease in the blood flow to the stomach. The butterfly sensation is part of what happens when your body goes into “fight or flight” mode.19世纪40年代晚期,两位医学研究者遇到一位不寻常的病人,他是一名军人,在他的胃部和肚皮之间有个创口。研究人员将这个创口当作观察病人胃部生理结构的窗口。他们发现如果病人处于压力条件下,胃部产生的酸会突然减少。他们还发现流向胃部的血液也会减少。这种蝴蝶感应正是你的身体进入战斗-逃跑模式时的反应。If youre confronted with a highly threatening situation, an important job interview, perhaps adrenaline floods into your bloodstream. This adrenaline raises your overall metabolism while it increases your heart rate and blood pressure. It also increases the sensitivity and strength of the smooth muscles in your stomach. This added sensitivity is what causes the fluttering sensation. Butterflies are just one way that your stomach can react to extra adrenaline.如果你面临着高度危急的情况,一场重要的求职面试,或许肾上腺素会像洪水般涌进你的血液中。肾上腺素会加快你全身的新陈代谢,让你心跳加快血压升高,同时还会使你胃部平滑肌的敏感度和力度增强。敏感度的提升又会导致蝴蝶感应。蝴蝶感应只是多余的肾上腺素作用于胃部的方式之一。If the adrenaline level continues to rise, the electrical activity in your stomach muscles increases and your stomach will begin contracting more frequently than usual. You will stop feeling butterflies, and your stomach will start feeling “tied in knots” instead. The best way to deal with these problems is to convince your body that its not in actual physical danger. Take a deep breath and relax. Job interviews arent that dangerous, are they?如果肾上腺素持续上升,胃部肌肉的生物电活动会增多,胃也会收缩得更频繁。这时你感受到的不是胃在颤抖,而是胃在打结。对付这个问题最好的办法就是说自己——身体没有陷入任何危险。深呼吸放轻松。不就是个求职面试么?原文译文属!201303/228802太仓较好的妇科医院 And for the record, thats faster than the speed of light. But wait. Doesnt that break one of the Laws of Physics?Even school children know that you e: you cant go faster than the speed of light.But actually there is a loophole there. You see nothing can go faster than light, nothing being empty space.记录显示那比光速更快。但是且慢。那会打破其中一条物理学定律吗?就连学校的学生都知道的那条定律:世界上最快的是光速。但实际上,这句话有漏洞。没有什么快于光速,而你所说的没什么是指空无一物的空间。 Dont worry. This idea gives even the best minds in science a headache. But its critical to understanding the early universe. Scientists think it took less than a millionth of a millionth of a millionth of a millionth of a second for the universe to expand from the size of an atom to a baseball.That may not sound like much, but its like a golf ball expanding to the size of the earth in the same amount of time.别担心,就算是最聪明的科学家也会对此感到头疼。然而了解早期的宇宙确实至关重要。科学家们认为如原子般大的宇宙膨胀到棒球大小需要的时间不超过万万万万亿分之一。也许听起来不是很形象,但这相当于花同样的时间由高尔夫球膨胀到地球样大小。That means it was expanding faster than the speed of light. Thats fast. So many things were happening so fast in the early universe. Because everything was so close together that we needed a new unit of time to describe things.这就意味着宇宙膨胀速度快于光速。那非常快。在早期的宇宙,许多事件发生得太快。因为每事件紧挨着发生,所以需要一个新的时间单位来描述物质的运动。Its called Planck Time. To understand just how short of Planck Time is, consider this, therere more units of Planck Time in one second than all the seconds since the Big Bang. The math is mind-blowing. Therere more than 31 million seconds in a year and its been 14 billion years since the Big Bang. So multiply 31,556,926 by 14 billion and what you get. Its a really big number.新的时间单位就是“普朗克时间”。要明白普朗克时间有多短,先要知道普朗克时间每秒包括的单位比大爆炸以来所有秒包括的单位都要多。计算起来很费脑筋。每年有3千多万秒,自大爆炸已经有140亿年了。140亿乘以31,556,926等于多少。一个巨大的数字。Its a time scale thats so small that all human intuition goes out (of) the window. If we look at our watches and measure one second, we can ask how many Planck Times is that. Well, it is a billion billion billion billion billion Planck Times.普朗克时间的时间段太小,超出了人类洞察力范畴。如果看表估量一秒钟,我们可以问这一秒钟的普朗克时间是多少。这么说吧,这一秒等于10的36次方普朗克时间。So, now the Big Bang is only a few Planck Times old in exploding mass of pure energy expanding faster than the speed of light. In the next few Planck Times, the universe as we know it will be born.因此,大爆炸开始的一瞬大量纯能量以快于光速的速率爆发膨胀,这个过程所用的普朗时间很短。接下来,在又一段很短的普朗克时间内宇宙就诞生了。201205/182472Science and Technology Prevention of cancer Wonder drug科技 预防癌症 特效药Aspirin continues to amaze阿司匹林让人吃惊的另一面FOR thousands of years aspirin has been humanitys wonder drug.几千年来,阿司匹林就一直是人类的特效药。Extracts from the willow tree have been used for pain relief in folk medicine since the time of the ancient Greeks.从古希腊开始,在民间医药中,人们就用柳树的萃取物缓解疼痛。By 1897 a synthetic derivative (acetyl salicylic acid) of the plants active ingredient (salicin) was created. This allowed aspirin to become the most widely used medicine in the world.1897年,这种植物中的有效成分的人工合成衍生物诞生了,于是阿司匹林变成了世界上应用最广泛的药品。In recent years its benefits as a blood-thinning drug have led to it being prescribed in low doses of around 50mg to reduce deaths from stroke and heart attack.最近几年,由于阿司匹林的防血凝功能,在用其治疗中风和心脏病的时候,剂量很小,维持在50mg的水平左右。There were also hints that aspirin may help prevent some cancers.也有迹象表明阿司匹林可以帮助预防一些癌症。But these were mostly based on observational studies, which can be misleading.不过这些结论大多都是在观察研究的基础上的,因而有可能产生误导。The gold standard of scientific evidence is the randomised controlled trial, preferably one with a lot of people and held over a long time.国际上科学据的标准是由随机对照实验得出的结果,尤其是那些有很多人参与又经过很长时间的实验。The results of just such a trial, published in the Lancet, suggest that aspirin is indeed an astonishing drug.而就是这样一份发表在《柳叶刀》上的论文表示阿司匹林的确是一种让人吃惊的药物。Peter Rothwell at the John Radcliffe Hospital in Oxford and his colleagues looked at deaths due to cancers during and after randomised trials of daily aspirin.来自牛津的约翰·拉德克里夫医院的彼得·罗思韦尔(Peter Rothwell)和他的同事们研究了在每日用阿司匹林的随机对照实验期间或者之后因癌症而死亡的病例。The trials had actually been started to look at how useful aspirin was for preventing heart attacks and strokes. Nevertheless, the data from the 25,570 patients enrolled in eight trials was also revealing about cancer.这一实验本是为了研究阿司匹林在防止心脏病和中风方面的疗效的,然而八项试验25570名患者的数据也揭示了阿司匹林对于癌症的疗效。In trials lasting between four and eight years, the patients who had been given aspirin were 21% less likely to die from cancer than those who had been given a placebo.在那些历时4到8年之间的实验中,用阿司匹林的患者因癌症而死亡的概率比那些用安慰剂的患者小了21%。These results were based on 674 cancer deaths, so are unlikely to represent the kind of statistical oddity that can beset studies on cancer risks that sometimes create headlines.这些结果是在674例癌症死亡病例的基础上得出的,所以不大可能是所谓的统计学上的例外。对癌症风险的研究会因这种例外而受挫,有时甚至会闹成大新闻。The benefits of aspirin were also apparent many years after the trials had ended.试验结束后的很多年后,阿司匹林的效果也仍旧明显。After five years, death rates for all cancers fell by 35% and for gastrointestinal cancers by 54%.五年后,所有癌症的死亡率下降了35%,而胃肠道癌症的死亡率则下降了54%。A long-term follow-up of patients showed that the 20-year risk of cancer death remained 20% lower in those who had taken aspirin.一项长期的病情跟踪报告显示,那些用阿司匹林的患者的20年内的癌症死亡风险比那些不用的低了20%。The study revealed that the effect takes time to accrue, so aspirin must be taken over a long period.这项研究揭示了阿司匹林的效果是随着时间而递增的,所以必须长期用才行。The latent period for improving oesophageal, pancreatic, brain and lung cancer was about five years of aspirin taking on a daily basis.For stomach and colorectal cancer the effects took ten years and for prostate cancer about 15 years.每日用阿司匹林对改善食管癌,胰腺癌,脑癌和肺癌的潜伏期为5年,对胃癌和结直肠癌则要花10年才能起作用,而前列腺癌则要15年。The means by which aspirin prevents cancer is not well understood.这意味着目前还不清楚阿司匹林到底是怎么预防癌症的。It is believed that it inhibits an enzyme that promotes cell proliferation in tumours.研究人员认为阿司匹林阻碍了一种在肿瘤内部促进细胞增殖的酶的活动。The researchers also found that small daily doses of aspirin were enough, and that taking more than 75mg conferred no additional benefits.研究者还发现,每天用小剂量的阿司匹林就已足够,剂量超过75mg后不会再增加效果。Those starting on aspirin in their late 40s or 50s benefit most.那些从四五十岁末就开始用阿司匹林的人得到的效果最好。Current guidelines on using aspirin for reducing the chances of a stroke or heart attack rightly warn of the small risk of ulcers and of dangerous bleeding in the stomach.目前在用阿司匹林治疗中风或者心脏病时,用药说明上会明确提醒有可能出现溃疡和危险性胃出血。These guidelines will probably have to be revised given the new findings.而鉴于这些新发现,这些说明很可能将要被修改了。However, it remains unlikely that popping aspirin will be recommended for everyone like a vitamin supplement.不过阿司匹林泡腾片不大可能像维生素补充剂一样被推广至每一个人。Aspirin is a highly cost-effective treatment: taking it for five to ten years easily beats initiatives to screen for breast and prostate cancers.用阿司匹林是一种非常划算的治疗:只要吃五到十年,就能打败那些让你做乳腺癌或者前列腺癌扫描的建议。To put it another way, ask yourself what a pharmaceuticals firm might charge for a drug that would reduce the chance of death by cancer by 20%—and then note that 100 days supply of low-dose aspirin can cost less than a dollar.换种说法,问问你自己,什么样的医药公司在看到100天的小剂量阿司匹林供应量还值不到一美元时,会对这种能够减少20%癌症死亡几率的药品开价呢?By anyones measure, that is a bargain.不管按照哪一方的标准,这都是一笔非常划算的交易。 /201301/220406太仓港口开发区人民妇幼中心医院治疗宫颈糜烂好吗

嘉定区妇幼保健人民医院官网IF CALIFORNIA were not aly so famous for Silicon Valley and Hollywood, it might be renowned for the cluster of water-technology firms in its San Diego County. The reverse-osmosis (RO) spiral module, the trick that underpins turning sea- and waste-water into potable stuff, was patented in San Diego in 1964. Today dozens of firms in the area supply many of the world’s roughly 13,000 RO plants in places from the Persian Gulf and Israel to Australia, China, Singapore and Spain.如果加利福利亚的出名不是因为硅谷和好莱坞,那么圣地亚哥大量的水处理公司也许会让它声名在外。反渗透膜元件1964在圣地亚哥被申请专利,该设备是将海水和废水转化为可饮用水的基础。当今全球约有13000家反渗透厂,它们分布在从波斯湾、以色列到澳大利亚、中国、新加坡和西班牙的地方。而其中的大多数厂商从圣地亚哥的水处理公司引进技术和设备。Southern California itself, however, has not so far been a big user of its own technology. This is surprising, given that the whole American south-west confronts a water problem. But there is at least now a growing consensus that the existing infrastructure, consisting of vast aqueducts that carry water from the Sacramento Delta in the north and the Colorado River in the east, will not suffice as the climate gets warmer and the population increases. In places such as San Diego, which has measly and brackish groundwater and currently imports 90% of its water, the answer must be greater conservation, as much reuse as possible, with most of the rest coming from the sea.然而到目前为止,南加州自身对水处理技术的运用并不广泛。这让人感觉到很惊讶,因为整个美国西南地区面临水资源匮乏问题。至少大家都逐渐认识到:随着气候变暖和人口增加,现存的基础设施(包括大量从北部的沙加緬度三角洲、东部的科罗拉多河铺设到西南地区的输水管道)将难以满足用水需求。圣地亚哥拥有的地下水储量既少,盐份又高,如今其90%的用水需从外地引入。在像圣地亚哥这样的地方,其对策是尽可能的节约用水、循环利用,而剩余不足的部份则大多从海洋中获取。 The first part, conservation, is hardly controversial any more. San Diego today uses less water with a larger population than it did in 1989, the year water consumption peaked. The second part, water recycling, has been a harder sell, because of what the industry calls the yuck factor. It doesn’t help that Americans still use the term “toilet-to-tap” for recycling, even though properly treated sewage is nowadays completely clean. Singapore made its programme acceptable in part by rebranding it as NEWater. But even the Singaporeans cannot recycle all their waste-water.首先,节约用水已被广泛认同。圣地亚哥如今人口增加了,耗水量却比1989年(耗水量最高的一年)少。其次,水循环利用很难被广泛接受,其原因在于业内所称的“恶心之物”。美国人民称水循环为“马桶-水龙头”,即使被恰当处理的污水十分干净,其也难去除人们的恶心之感。新加坡使其在理论上被接受,部分原因在于它把处理过的污水称为新生水。但是,即使是新加坡人也不能循环利用所有的废水。This is where desalination comes in. A firm appropriately called Poseidon Resources is now close to building the biggest desalination plant in America behind a power station by the beach in Carlsbad. The power plant sucks in 304m gallons of seawater a day for cooling in any case, so Poseidon plans to divert 104m gallons a day through its osmotic membranes.海水淡化技术就因此出现了。恰如其名,Poseidon Resources公司将在美国修建最大的海水淡化厂,其厂址位于卡尔斯巴德的海滩附近的发电站后面。发电站每日总会吸取30400万加仑海水用于冷却,因此Poseidon计划每日用渗透膜淡化10400万加仑海水。Fondling a pipe of membranes (they are rolled like toilet paper but the size of a cannon), Poseidon’s Peter MacLaggan explains the scale: if water molecules were blown up to the size of tennis balls, salt molecules would be softballs (roughly 50% bigger in diameter), viruses would be trucks, and bacteria would be the size of power plants. From the 104m daily gallons, 50m gallons of pure H2O will come out at one end and brine at the other, to be fed back into the power station’s discharge, and then into the ocean.渗透膜如同卫生纸一样卷起来的,但却有大炮那么大。Poseidon的Peter MacLaggan一边摸着渗透膜一边解释道:如果水分子胀大到乒乓球大小,盐分子有垒球大(在直径上大约长50%),病毒有卡车那么大,细菌有发电厂那么大。在每天处理的10400万加仑海水中,有5000万加仑的纯水从渗透膜一端流出,然后在其另一端变成浓盐水,最终由发电厂的排放系统流回海里。Lots of people like the idea. Once fully running in 2015 the plant could produce 10% of the region’s water. And there are plans for more desalination plants. Inland Californians, Arizonans, Nevadans and others would need to take much less water from the endangered Colorado River.很多人赞同这种想法。到2015年,一旦Poseidon全部投入运行,其可以提供该地区用水的10%。而且有许多厂准备加入海水淡化处理队伍。加利福利亚内陆、亚利桑那州、内华达州和其它地方从日渐干涸的科罗拉多河中抽取的水将越来越少。But a few people hate it a lot. Environmentalists are suing Poseidon every step of the way. Joe Geever of the Surfrider Foundation says desalination uses too much energy and that Poseidon’s plant would kill too much marine life, including fish such as the goby and the garibaldi, which unfortunately happens to be California’s state marine fish. He understands that there is a role for desalination, he says, but would rather not have it right there, right now, and on this scale.但是也有一些人极不赞同。环境保护者正在起诉Poseidon海水淡化方式的每一步骤。冲浪协会的Joe Geever说:“海水淡化耗费太多的能源,而且Poseidon会伤害许多海洋动物诸如虾虎鱼、海金鱼之类的鱼类,而后者恰好是加州的海洋鱼。”他说,他知道海水淡化的重要性,但是相对于其来带的利弊,他宁愿加州此刻没有这么大规模的海水淡化厂。201204/177102 上海嘉定妇幼保健人民医院检查白带多少钱嘉定区妇幼保健人民医院可以做引产吗
