贵阳乳腺医院贵阳医学院第三附属医院人流收费标准A string of Twitter accounts have been closed after they were revealed to contain disturbing images of child abuse.在他们被发现含有令人不安的虐童照之后一连串的推特帐户已经被关闭。The graphic pictures were apparently made public late last night after hacking groups claimed to have broken into private accounts to expose their indecent content, the NSPCC said.照片显然是在昨晚晚些时候公开的,在黑客组织声称已经潜入私人账户来爆出他们的不雅内容,全国防止虐待儿童协会说。The charity said it received a ;flurry; of reports overnight relating to at least half a dozen Twitter accounts which were later disabled.该慈善机构表示一夜之间它收到了一系列涉及至少半打后来被禁用的Twitter账户的报告。They will now be investigated in the US, where the micro-blogging site is based.他们现在将在美国被调查,那里是微网站的建立地。An NSPCC spokesman said: ;Apparently these were pretty disturbing images of child abuse.英国防止虐待儿童协会的发言人说:“很显然这是非常令人不安的虐待儿童照。;We understand the authorities in the US are now looking at the accounts.;“我们理解美国当局现在正在调查这些账户。”The Child Exploitation and Online Protection Centre (Ceop) said it had also received around 30 reports, relating to at least four accounts.为儿童提供互联网在线保护的开发中心(Ceop)表示它也收到约30份报告,涉及至少四个账户。A spokesman added: ;Twitter are obliged by law to send details of any accounts containing indecent images of children to the National Centre for Missing and Exploited Children [NCMEC] in the US.一位发言人补充道:“Twitter有法律义务把包含儿童不雅照的任何帐户细节发给在美国的国家失踪与受虐儿童援助中心[NCMEC]。;NCMEC will then forward information for investigation to law enforcement agencies in the relevant country where the user is believed to be based, or children believed to be at risk.;“NCMEC将把用于调查的信息发送到那些相关国家的执法机构,他们认为用户是基础或孩子们存在风险。”Authorities were first alerted to the apparent abuse by a number of Twitter users at around 11.30pm.在下午11:30左右当局第一次惊醒到这个由很多Twitter用户进行的明显滥用。 This came after hackers apparently opened up a number of private accounts which were previously kept hidden from public view, the NSPCC said.在黑客显而易见地开放了许多以前淡出公众视线的私人账户之后事情发生了,全国防止虐待儿童协会说。It remains unclear whether any of the images were uploaded by a British user or a user based abroad.目前尚不清楚图片是否由英国用户或海外用户上传。The nationalities of any children involved are also unknown.涉及的任何一个孩子的国籍也是未知的。Twitter has yet to comment on the images but has apparently issued a response to anyone contacting the company over the images of alleged abuse.Twitter尚未对这些图片发表,但显然已经就所谓的虐待照与该公司有关的任何人作出了回应。 This s: ;We do not tolerate child pornography on Twitter. When we are made aware of such images they will be removed from the site without further notice.;上面写着:“我们不能容忍Twitter上有儿童色情内容。当我们被告知这些图片时他们将从网站移除,不另行通知。” /201212/216603安顺市医院体检收费标准 Facebook and Microsoft Corp representatives said Friday night that after negotiations with national security officials, their companies have been given permission to make new but still very limited revelations about government orders to turn over user data.Facebook和微软公司代表说周五晚上在与国家安全局官员谈判后,他们公司已经得到允许可以披露新的但仍然非常有限的关于政府命令提交的用户数据。The announcements come at the end of a week when Facebook, Microsoft and Google, normally rivals, had jointly pressured the Obama administration to loosen their legal gag on national security orders.当Facebook、微软和谷歌,通常的对手,联合迫使奥巴马政府放松了对国家安全命令的法律禁言,公告在一周结束时出来。Those actions came after Edward Snowden, a contract employee at the National Security Agency, revealed to The Guardian newspaper the existence of secret surveillance programs that gathered Americans#39; phone records and other data. The companies did not link their actions to Snowden#39;s leaks.这些行动是在爱德华#8226;斯诺登,国家安全局的一名雇员向《卫报》透露存在收集美国人电话记录和其他数据的秘密监视程序后出来的。这些公司没有将他们的行为与斯诺登的泄漏相联系。Ted Ullyot, Facebook#39;s general counsel, said that Facebook is only allowed to talk about total numbers and must give no specifics. But he said the permission it has received is still unprecedented, and the company was lobbying to reveal more.Facebook的首席法律顾问Ted Ullyot说Facebook只允许谈论总数,不能给细节。但他说得到的允许仍然是前所未有的,公司正游说透露更多。Using the new guidelines, Ullyot said Facebook received between 9,000 and 10,000 government requests from all government entities from local to federal in the last six months of 2012, on topics including missing children investigations, fugitive tracking and terrorist threats. The requests involved the accounts of between 18,000 and 19,000 Facebook users.使用新的指导方针,Ullyot说Facebook在2012年下半年接到9千到1万条政府请求,从美国联邦到州及各级地方政府,主题包括失踪儿童调查、逃亡跟踪和恐怖主义威胁。这些资料信息涉及1.8万至1.9万名脸谱用户。 /201306/244103贵 阳 安 全 无 痛 人 流 医 院

贵州电力职工医院看妇科好不好Behind the hellish Ebola epidemic ravaging West Africa lies an agent that fittingly embodies the mad contradictions of a nightmare. It is alive yet dead, simple yet complex, mindless yet prophetic, seemingly able to anticipate our every move.在埃拉疫情侵袭西非的背后有一个恰好能体现一场噩梦矛盾之处的载体。它活着但已经死了,简单而又复杂,盲目而又具先知性,似乎能够预见我们的每一个举动。For scientists who study the evolution and behavior of viruses, the Ebola pathogen is performing true to its vast, ancient and staggeringly diverse kind. By all evidence, researchers say, viruses have been parasitizing living cells since the first cells arose on earth nearly four billion years ago.对于研究病毒演变及行为的科学家来说,埃拉病原体的本质与数量庞大、历史悠久、形态各异的各种病毒并无不同。研究人员称,所有的据都显示,自大约40亿年前地球上出现第一批细胞开始,病毒就一直寄生在活细胞当中。Some researchers go so far as to suggest that viruses predate their hosts. That they essentially invented cells as a reliable and renewable resource they could then exploit for the sake of making new viral particles.一些研究人员甚至表示,病毒先于宿主出现。它们基本上创造了细胞,并将其当做可靠的、可延续的资源,日后可以用来产生新病毒。It was the primordial viral ;collective,; said Luis P. Villarreal, director of the Center for Virus Research at the University of California, Irvine, ;that originated the capacity for life to be self-sustaining.;加州大学欧文分校(University of California, Irvine)病毒研究中心(Center for Virus Research)主任路易斯·维拉里尔(Luis P. Villarreal)说,“生命的自我维持能力源于”原始的病毒“团体”。;Viruses are not just these threatening or annoying parasitic agents,; he added. ;They#39;re the creative front of biology, where things get figured out, and they always have been.;“病毒不仅仅是危险的、令人讨厌的寄生体,”他还说。“它们还处于生物学的创新前沿,为问题的解决做着贡献,它们也一直都是这样的。”Researchers are deeply impressed by the depth and bth of the viral universe, or virome. Viruses have managed to infiltrate the cells of every life form known to science. They infect animals, plants, bacteria, slime mold, even larger viruses. They replicate in their host cells so prodigiously and stream out into their surroundings so continuously that if you collected all the viral flotsam afloat in the world#39;s oceans, the combined tonnage would outweigh that of all the blue whales.病毒世界的深度与广度给研究人员留下了深刻的印象。病毒已成功侵入科学界已知的每一种生命形式的细胞中。它们会感染动物、植物、细菌、粘液菌,甚至是较大的病毒。它们在宿主细胞中大量复制,不断涌入周围环境。如果将全球海洋里漂浮的所有病毒性物质收集起来,总重会超过所有蓝鲸的重量。Not that viruses want to float freely. As so-called obligate parasites entirely dependent on host cells to replicate their tiny genomes and fabricate their protein packages newborn viruses, or virions, must find their way to fresh hosts or they will quickly fall apart, especially when exposed to sun, air or salt.病毒并非想要四处漂泊。由于所谓的专性寄生物完全依赖宿主细胞复制它们极小的基因组及合成蛋白,因此新产生的病毒或病毒粒子必须找到新宿主,否则它们就会迅速崩溃,特别是暴露在太阳、空气或盐中的时候。;Drying out is a death knell for viral particles,; said Lynn W. Enquist, a virologist at Princeton.普林斯顿大学(Princeton University)病毒学家林恩·W·恩奎斯特(Lynn W. Enquist)说,“对于病毒粒子来说,干燥的环境意味着死亡。”How long shed virions can persist if kept moist and unbuffeted — for example, in soil or in body excretions like blood or vomit — is not always clear but may be up to a week or two. That is why the sheets and clothing of Ebola patients must be treated as hazardous waste and surfaces hosed down with bleach.目前并不是十分清楚,如果保持潮湿且不受打击,例如在土壤或血液、呕吐物等人体排出的物质中,分离的病毒粒子能够维持多长时间,但可能最多是一两周。因此,埃拉患者的床单和衣必须被当作危险废物处理,表面都得用漂白剂冲洗。Viruses are masters at making their way from host to host and cell to cell, using every possible channel. Whenever biologists discover a new way that body cells communicate with one another, sure enough, there#39;s a virus aly tapping into exactly that circuit in its search for new meat.病毒善于通过一切可能的途径,从一个宿主进入另一个宿主,从一个细胞进入另一个细胞。每当生物学家发现身体细胞交换信息的新方式后,果然就已经有病毒在利用这个通道,寻找新目标。Reporting recently in Proceedings of the National Academy of Sciences, Karla Kirkegaard, a professor of microbiology and genetics at Stanford University School of Medicine, and her colleagues described a kind of ;unconventional secretion; pathway based on so-called autophagy, or self-eating, in which cells digest small parts of themselves and release the pieces into their surroundings as signaling molecules targeted at other cells — telling them, for example, that it#39;s time for a new round of tissue growth.最近,斯坦福大学医学院(Stanford University School of Medicine)微生物学及基因学教授卡拉·柯克加德(Karla Kirkegaard)和同事在《国家科学院院刊》(Proceedings of the National Academy of Sciences)发表文章描述了一种基于所谓的自噬的“非传统分泌”途径,即细胞消化一部分自身细胞质,然后将它们释放到周围的环境中,充当针对其他细胞的信号分子,比如,告诉它们,现在是进行新一轮组织生长的时候了。The researchers determined that the poliovirus can exploit the autophagy conduit to cunning effect. Whereas it was long believed that new polio particles could exit their natal cell only by bursting it open and then seeking new cells to infect, the researchers found that the virions could piggyback to freedom along the autophagy pathway.研究人员断定,小儿麻痹症病毒能够非常巧妙地利用这条自噬途径来达成目的。从前,人们一直以为,新的小儿麻痹症病毒粒子脱离产生这些病毒的细胞的唯一方式就是冲破细胞,寻找并感染新细胞,而研究人员发现病毒粒子能够在自噬的过程中搭便车,从而获得自由。In that way, the virus could expand its infectious empire without destroying perfectly good viral factories en route. The researchers suspect that other so-called naked or nonenveloped viruses (like the cold virus and the enteroviruses that have lately plagued children in this country and Asia) could likewise sp through unconventional secretion pathways.如此一来,病毒可以在不破坏完美的病毒工厂的情况下扩大传染范围。研究人员推测,其他所谓的裸病毒或无包膜病毒(比如最近困扰美国及亚洲儿童的感冒病毒和肠道病毒)同样能够通过非传统分泌途径传播。For their part, viruses like Ebola have figured out how to slip in and out of cells without kicking up a fuss by cloaking themselves in a layer of greasy lipids stolen from the host cell membrane, rather as you might foist a pill down a pet#39;s throat by smearing it in butter.埃拉等病毒已经知道如何在从宿主细胞的细胞膜中盗取的一层脂质的掩护下悄悄进入、脱离细胞,就像你用抹上黄油的药片去喂食宠物一样。According to Eric O. Freed, the head of the virus-cell interaction section at the National Cancer Institute, several recent technological breakthroughs have revolutionized the study of viruses.美国国家癌症研究所(National Cancer Institute)病毒与细胞互动部门的主管埃里克·O·弗里德(Eric O. Freed)表示,最近几项技术突破使病毒研究发生了巨大变革。Advances in electron microscopy and super-resolved fluorescence microscopy — the subject of this year#39;s Nobel Prize in Chemistry — allow scientists to track the movement of viral particles in and between cells, and to explore the fine atomic structure of a virus embraced by an antibody, or a virus clasped onto the protein lock of a cell.电子显微镜和超高分辨率荧光显微镜的发展使得科学家能够追踪病毒粒子在细胞内及细胞间的活动,了解被抗体包围的病毒或细胞蛋白结合位上的病毒的精细原子结构。今年的诺贝尔化学奖就颁发给了对超高分辨率荧光显微镜发展做出贡献的科学家。Through ultrafast gene sequencing and targeted gene silencing techniques, researchers have identified genes critical to viral infection and drug resistance. ;We#39;ve discovered viruses we didn#39;t even know existed,; Dr. Freed said. And that could prove important to detecting the emergence of a new lethal strain.研究人员已经通过快速基因测序及靶基因沉默技术,确定了对病毒感染及抗药性至关重要的基因。弗里德士说,“我们发现了之前不知道的病毒。”事实可能会明,这对新的致命病毒的探测非常重要。Viruses are also notable for what they lack. They have no ribosomes, the cellular components that fabricate the proteins that do all the work of keeping cells alive.病毒还有一个显著特点,它们缺少一些东西。它们没有核糖体——合成蛋白的细胞器,而蛋白是维持细胞存活的物质。Instead, viruses carry instructions for co-opting the ribosomes of their host, and repurposing them to the job of churning out capsid and other viral proteins. Other host components are enlisted to help copy the instructions for building new viruses, in the form of DNA or RNA, and to install those concise nucleic texts in the newly constructed capsids.但病毒会携带利用其宿主核糖体的指令,改变它们的用途,使它们合成大量衣壳及其他病毒蛋白。宿主细胞的其他部分则被用于帮助复制发展新病毒的指令——其形式表现为DNA或RNA,并将这些简单的核素安置在新合成的衣壳中。;Viruses are almost miraculously devious,; Dr. Freed said. ;They#39;re just bundles of protein and nucleic acid, and they#39;re able to get into cells and run the show.;“病毒极其狡诈,”弗里德士说。“虽然它们只不过是一堆蛋白和核酸,它们却能侵入细胞,控制细胞。”;On the one hand, they#39;re quite simple,; Dr. Enquist said. ;On the other hand, they may be the most highly evolved form of genetic information on the planet.;“一方面,它们非常简单,;恩奎斯特士说。“另一方面,它们可能是地球上进化程度最高的遗传信息形式。;Viruses also work tirelessly to evade the immune system that seeks to destroy them. One of the deadliest features of the Ebola virus is its capacity to cripple the body#39;s first line of defense against a new pathogen, by blocking the release of interferon.病毒还坚持不懈地躲避着试图摧毁它们的免疫系统。埃拉病毒能够阻碍干扰素的释放,突破人体防御新病菌的第一道防线,这也是该病毒最致命的特征之一。;That gives the virus a big advantage to grow and sp,; said Christopher F. Basler, a professor of microbiology at Mount Sinai School of Medicine.西奈山医学院(Mount Sinai School of Medicine)微生物学教授克里斯托弗·F·巴斯勒(Christopher F. Basler)说,“这给了这种病毒巨大的优势,有助于它的增长和传播。”At the same time, said Aftab Ansari of Emory University School of Medicine, the virus disables the body#39;s coagulation system, leading to uncontrolled bleeding. By the time the body can rally its second line of defense, the adaptive immune system, it is often too late.埃默里大学医学院的(Emory University School of Medicine)的阿夫塔卜·安萨里(Aftab Ansari)表示,与此同时,病毒破坏了人体凝血系统,导致人体不可控制地出血。等到人体筑起第二道防线——适应性免疫系统时,通常为时已晚。Yet the real lethality of Ebola, Dr. Ansari said, stems from a case of mistaken location, a zoonotic jump from wild animal to human being. The normal host for Ebola virus is the fruit bat, in which the virus replicates at a moderate pace without killing or noticeably sickening the bat.但安萨里士表示,埃拉病毒真正的杀伤力源于错放了位置,从野生动物跨物种感染了人类。埃拉病毒的宿主通常是果蝠,病毒在不使果蝠死亡或明显患病的情况下稳步复制。;A perfect parasite is able to replicate and not kill its host,; Dr. Ansari said. ;The Ebola virus is the perfect parasite for a bat.;“完美的寄生生物能够复制,且不杀死宿主,”安萨里说。“埃拉病毒是蝙蝠身上的完美寄生物。” /201410/338773息烽县治疗内分泌多少钱 贵阳盆腔炎

贵阳市南明区人民医院做彩超多少钱 One of the big mysteries in corporate America is whether telecom regulators will allow theComcast/Time Warner Cable merger, announced in February, to close. President Obama’s comments on net neutrality on Monday provide a clue: the government is going to make the business of delivering internet less attractive. This could undercut some of the objections to the deal.美国商界的一大疑团是:电信监管机构会不会让今年2月宣布的康卡斯特(Comcast)/时代华纳有线(Time Warner Cable)合并交易顺利完成。美国总统奥巴马周一有关网络中立的言论提供了一条线索:政府将降低提供互联网接入务的吸引力。这会化解一部分针对上述交易的阻力。The White House statement said Mr Obama favoured reclassifying internet service providers such as Comcast and TWC as “common carriers”. Such a move by the Federal Communications Commission (which is independent of the president) would regulate ISPs like utilities. The president favours prohibiting “paid prioritisation” in which content providers buy access to faster distribution.白宫声明称,奥巴马主张将互联网务提供商(ISP)(例如康卡斯特和时代华纳有线)重新归类为“公共通信企业”。独立于美国总统的联邦通信委员会(FCC)若采取这一举措,会像监管公用事业公司那样监管互联网务提供商。奥巴马还主张禁止;有偿优先;,即内容提供商通过付费获得更高速度的分发。Netflix struck such deals with several ISPs (including Comcast) this year but has since complained about them.今年Netflix公司就跟几家互联网务提供商(包括康卡斯特)达成这样的交易,但之后对此抱怨诸多。The net neutrality debate has taken on a David vs Goliath flavour. Scrappy Netflix heroically provides television and movies for just per month while distributors gouge profits from their control of the pipes.关于网络中立的辩论如今带有圣经故事中大卫对决歌利亚的意味。斗志昂扬的Netflix公司英勇地以每月8美元的价格提供影视内容,而互联网务提供商则利用自己对管道的控制,抢占了大部分利润。The Netflix monthly fee roughly reflects the cost of acquiring content. The question then is whether that fee should jump to reflect the operating and capital costs Comcast incurs to deliver that content. Comcast and Time Warner are profitable businesses, unlike Netflix. But they are extremely capital intensive.Netflix的月租费大致反映了获取内容的成本。问题在于,应不应该大幅提高收费,以反映康卡斯特为投送这些内容而产生的运营和资金成本?康卡斯特和时代华纳是盈利企业,不像Netflix。但他们也是极度资本密集的。Comcast shares shed four per cent on Monday perhaps to the delight of its oft-irritated customers. But schadenfreude aside, US internet service remains slow and expensive compared with the rest of the world.康卡斯特的股价周一下挫4%,也许会令那些平时不满的顾客感到窃喜。但幸灾乐祸之余,美国的互联网务相对于世界其他国家仍是缓慢和昂贵的。It is fun to fantasise about reallocating Comcast profits to Netflix. But consumers and their advocates should think about what competitive framework would lead to the necessary investment in broadband infrastructure.幻想一下将康卡斯特的利润重新分配给Netflix是好玩的。但消费者和持他们的人应该想一想,什么样的竞争框架才会给网络宽带基础设施带来必要的投资。The costs of delivering content can be shared, but not avoided.投送内容的成本可以被分担,但无法避免。 /201411/342244贵 阳 做 无 痛 人 流 什 么 医 院 最 好贵阳医院在线咨询
