VOA慢速英语:'Scent Device' Called OdoReader Can Identify Bladder Cancer

Bladder cancer is the ninth most common cancer in the world, an estimated 12 million new cases are found every year. Now, researchers say they have developed a "scent device" that can identify the disease.
膀胱癌是全球最常见的九种癌症之一，估计每年有1200万新发病例。现在，研究人员称，他们已经开发出一种“气味装置”可以识别该疾病。

The device is called the OdoReader, it has a sensor that finds chemicals in the gases released by urine.
这种装置被称为“OdoReader”，它有一个传感器能够发现尿液释放出气体中的化学物质。

The device takes about 30 minutes to analyze the odors in a urine sample, to find if a person has bladder cancer.
该设置需要花费约30分钟来分析尿液样本中的气味，以确定一个人是否有膀胱癌。

The Institute of Biosensor Technology at the University of the West of England in Bristol developed the device.
布里斯托尔市西英格兰大学的生物传感技术研究所发明了这一装置。

Chris Probert at the University of Liverpool was part of a team that tested it. Mr Probert says the results are highly accurate.
利物浦大学的Chris Probert是测试该装置的团队中的一员。Probert先生称，结果是非常准确的。

"This data set is very strong: 96-100 percent accuracy. We think we are right for the next study to show that it is reproducible and then, hopefully, we can talk to industry about making a box that people can buy for use in surgeries and hospitals."
“这组数据是非常强大的：准确率达到96%至100%。我们认为我们应该进行下一步研究以表明它具有可重复性。那么，希望我们可以和有关行业商谈制造这样一个盒子，人们可以购买它用于诊室和医院。”

Researchers tested the OdoReader on 98 urine samples. 24 of them were from patients known to have bladder cancer, 74 were from people who had bladder infections, but not bladder cancer. The device identified everyone of the patients who had bladder cancer.
研究人员用OdoReader测试了98份尿液样本。其中24份样本来已知有自膀胱癌患者，另外74份样本来自膀胱感染而不是膀胱癌的患者。该装置识别出了所有膀胱癌患者。

Mr Probert says researchers in other labs are developing sniffing devices to diagnose stomach cancer, another common disease worldwide.
Probert先生称，其他实验室的研究人员正在开发嗅探设备用于诊断胃癌，这是世界范围内另一种常见的疾病。

Researchers say the OdoReader is like a dog's nose. An earlier study showed that dogs could be trained to detect bladder cancer based on the odor of urine. However, the dog's noses was not nearly as reliable as the new device.
研究人员称，OdoReader就像是狗的鼻子。先前的研究表明，狗经过训练可以通过尿液气味检测出膀胱癌。然而，狗的鼻子没有该新设备可靠。

Mr Probert says the scent device could someday be used to monitor the health of workers in industries like rubber and insulation manufacturing.
Probert先生称，这种气味设备有一天可以用于监测橡胶和绝缘制造业等行业工人的健康。

"There's quite a burden of cancer in those employees. And so, occupational health in those places of work could help their employees by taking a urine sample, much as they are doing now but with much more accuracy with our machine."
“这些员工中许多人有癌症的负担。因此，这些地方的职业保健工作可以通过采集尿样来帮助他们的员工，就像他们现在正在做的一样，但我们的机器更准确。”

Bladder cancer is now found by looking for the blood in the urine.
膀胱癌目前是通过检测尿液中的血液来发现。

Mr Probert says researchers have not yet identified which gases in urine make the scent unique to bladder cancer. But he says they are working on that. They are also working on other odor reading devices to diagnose other cancers, including those of the uterus and colon.
Probert先生说，研究人员尚未确定尿液中的哪种气体使得膀胱癌具有独特的气味。但他说，他们正致力于此。他们也正致力于其它气味读取设备来诊断包括子宫癌和结肠癌在内的其它癌症。

The journal PLoS ONE, from the Public Library of Science published an article by Chris Probert and his colleagues on the OdoReader.
公共科学图书馆期刊《PLoS ONE》发表了Chris Probert和他的同事关于OdoReader的一篇文章。
