长宁区人民医院玻尿酸隆鼻多少钱上海曙光医院西院做去疤手术价格Doctors from the Children#39;s Hospital of Philadelphia have invented an artificial womb to support critically premature babies, according to a study published in Nature Communications.根据一项发表在《自然通讯》上的研究显示,费城儿童医院的医生们发明了一种可以维持重度早产儿发育的人造子宫。In their experiment, six premature lambs were placed in artificial wombs immediately after caesarean deliveries at the equivalent of 23 weeks human gestation.在实验中,6只相当于人类期23周的早产小羊在剖腹产之后被立刻放入人造子宫。In the biobag, the lambs were immersed in a substitute amniotic fluid containing nutrients and chemicals designed to stimulate growth.在这种生物袋里,这些小羊被浸入到含有养分和化学物质的替代羊水中以促进发育。While floating inside the transparent plastic vessel - in some cases for four weeks - the lambs appeared to develop normally, transforming from bald, pink fetuses into fleecy, white newborns.在这种透明塑料容器中漂浮的过程中,这些小羊似乎正常发育了(有些情况下只需4周),从光秃秃、粉嫩嫩的胎儿变成了毛茸茸的白色新生羊羔。Doctors said that the pioneering approach could radically improve outcomes for human babies born so early that they cannot breathe, feed or fight infection without medical help.医生们称,这种开创性的方法可以彻底改善人类早产儿不经医疗辅助就无法呼吸、进食、抵抗感染的状况。;If we can support growth and organ maturation for only a few weeks, we can dramatically improve outcomes for extremely premature babies,; Alan Flake, a foetal surgeon at the Children#39;s Hospital of Philadelphia (CHOP) and lead author said.费城儿童医院的胎儿外科医生、该研究的首席作者艾伦·弗莱克表示:“如果我们能在胎儿发育和器官成熟方面提供几个星期的帮助,那么我们就能极大的改善早产儿的情况。” /201705/508873上海附属医院去胎记多少钱 Buddy is a sleeping beauty: Reddish brown, he's usually asleepon his back, snoring loudly with his large tongue lolling out.He was wide-awake Monday, though, when he was crowned winner of a "Beautiful Bulldog" contest."He doesn't have a good stamina to him ... he's been laying around all winter," said George DuBois from Ankeny, Iowa, who owns Buddy with his wife, Cindy. "Just in the last 10, 15 days we've done some walking. We've been getting in shape for this."Buddy was among 50 bulldogs from mostly Midwestern states who came to compete. The contest was among events leading up to the Drake Relays, one of the nation's oldest and most prestigious track and field competitions."I'm so excited. I didn't think he had what it took to get it," said Cindy DuBois.Buddy competed unadorned, unlike many of his rivals. They dressed up as fairy princesses, rock stars, cheerleaders, bumblebees and even Snow White and Mr. T.Bella Star of Elmwood, Ill., had her nails painted red and wore a Hawaiian lei, pink bikini top and a grass skirt. The skirt slipped off as she strutted down the "dogwalk" before the judges.Buddy panted heavily as he sat on his throne, getting used to his new crown and cape as photographers snapped his picture. On Saturday, he'll ride in a golf cart at Drake Stadium before about 18,000 spectators."I don't think he really wants attention all that much," said George DuBois. "He's just a rascal." 一身红棕毛的巴迪可是个名副其实的“睡美人”:他总是仰面朝天,拖着大舌头,呼呼大睡。但周一那天他很清醒,因为他夺得了“最靓斗牛犬选美大赛”的冠军。巴迪是来自艾奥瓦州安科尼市的乔治#8226;杜波伊斯和妻子辛蒂的爱犬。乔治说:“巴迪体力不好,整个冬天他几乎都在躺着。直到比赛前10天到15天,我们才带他出去遛了遛,主要是为比赛做准备。”今年的选美比赛共有50只斗牛犬参加,其中大多数来自美国中西部地区。该比赛拉开了德雷克大学接力赛的序幕,德雷克大学接力赛是美国最古老、最具名望的田径赛事之一。辛蒂说:“我太激动了。没想到他能拿冠军。”参赛的斗牛犬们有的打扮得像公主、有的像摇滚明星、有的像拉拉队队长、大黄蜂,有的甚至打扮成了白雪公主和Mr.T。而与其它参赛选手不同的是,巴迪几乎“未施粉黛”。来自伊利诺伊州艾尔姆伍德市的参赛选手贝拉#8226;斯塔尔涂着红指甲、头戴夏威夷花环,身穿粉色比基尼内衣和草裙。不过她在裁判面前秀“步”时,草裙不慎滑落。巴迪气喘吁吁地坐在冠军宝座上,头戴王冠、身穿披风,从容不迫地面对摄影师的镜头。他将于本周六乘坐一辆高尔夫球车进入德雷克体育馆,与约18000名观众见面。乔治说:“他肯定不愿受到这么多关注。他只不过是个淘气鬼。” /200804/36816上海整形丰胸医院
