New Test for H5N1,and New Findings Why Virus Is So Deadly (1/2)
检测H5N1病毒的新方法,新的研究结果揭示该病毒为何如此致命!
【今日听写、翻译】
Scientists continue to look for ways to deal with the deadly form of bird flu virus.Researchers in Singapore,for example,have developed a new test for the H5N1 virus.They call it a "lab on a trip chip."
科学家们继续寻找应对禽流感病毒致死性结构的方法,例如,新加坡的研究者已完成了一项新的检测H5N1病毒的方法,他们称这为“芯片上的实验室”.
If successfully marketed,the hand-held device could be used to look for cases in infected affected areas and help contain outbreaks.Project leader Juergen Pipper says medical or aide aid workers would know in less than half an hour if a person is infected.
如果能在市场上成功推广,此项手工操作的技术可用来在受感染地区搜索病例以及帮助控制疫情暴发.项目领导者Juergen Pipper声称如果使用此法,医疗工作人员或辅助人员可在不到半个小时之内分辨某人是否已被感染.
The device tests material collected from a quick swap swab of a person’s throat.The test uses magnetic force to control individual droplets containing added magnetic particles.The scientists say the droplet itself becomes a little laboratory that can do things like pump,separate and mix.They know note that an increasing number of similar tests are available to process cells,genetic material and proteins.
此项技术检测来自快速擦拭人体咽喉后所获得的拭样.它利用磁力来控制含有附加磁性粒子的个体唾沫液滴.科学家声称此唾沫液滴本身就成为了一小型试验室,可进行泵吸、分离和混合等加工程序.他们也指出越来越多的同类检测方法已应用到对细胞、基因材料和蛋白质的研究.
Juergen Pipper says the device can process complex tests tasks in a way similar to a traditional biological laboratory.The researchers say it works about ten times faster than current tests for the virus and could cause cost much less.The developers think the same idea could also be used to find other viruses,including those that cause AIDS,SARS and hepatitis B.Their research was published in Nature Medicine.
Juergen Pipper指出此项技术,如同传统生物实验室一样,能完成复杂任务.研究者声称它比以往检测该病毒的检测方法快了约10倍,而且成本更少.此项技术开发者认为可利用相同的理念来检测其它病毒,包括那些导致艾滋病、非典型性肺炎和乙型肝炎的病毒.相关的研究结果已发布在《自然医学》期刊上.

Scientists continue to look for ways to deal with the deadly form of bird flu virus.

Researchers in Singapore, for example, have developed a new test for the h-five-n-one virus. They call it a "lab on a chip."
If successfully marketed, the hand-held device could be used to look for cases in affected areas and help contain outbreaks. Project leader Juergen Pipper says medical or aid workers would know in less than half an hour if a person is infected.
The device tests material collected from a quick swab of a person’s throat. The test uses magnetic force to control individual droplets containing added magnetic particles. The scientists say the droplet itself becomes a little laboratory that can do things like pump, separate and mix.
They note that an increasing number of similar tests are available to process cells, genetic material and proteins.
Juergen Pipper says the device can process complex tasks in a way similar to a traditional biological laboratory. The researchers say it works about ten times faster than current tests for the virus and could cost much less.
The developers think the same idea could also be used to find other viruses, including those that cause AIDS, SARS and hepatitis B.
Their research was published in Nature Medicine.
As of Tuesday, the World Health Organization had counted three hundred twenty-nine cases of the bird flu virus since two thousand three.
Sixty percent of the patients died. Many experts worry that the virus could kill large numbers worldwide if it starts to spread easily from person to person.
Indonesia has had the most cases, more than one hundred, and the most deaths. Last Friday a twenty-one-year-old man from west Jakarta became the eighty-sixth victim. Health officials say they do not know how he became infected.
An international team reported last week that the virus is so destructive, it can even infect unborn children. Researchers studied the bodies of two people killed by h-five-n-one. The study appeared in the Lancet.
They found that the virus caused a surprising amount of damage to the lungs. It also spread to the brain and to the digestive and reproductive systems. Ian Lipkin at Columbia University in New York says one victim was pregnant and the virus had spread to her fetus.
Yet the findings may help point to ways to limit damage by targeting not only the virus itself, but also how the body reacts.
And that’s the VOA Special English Health Report, written by Caty Weaver. I’m Mario Ritter.
