SAN FRANCISCO Jared Goff Rams Jersey , Aug. 30 (Xinhua) -- University of Washington (UW) researchers are developing a software application, or app, to allow people to screen for pancreatic cancer and other diseases by snapping a smartphone selfie.

With a five-year survival rate of 9 percent, pancreatic cancer has one of the worst prognoses in part because there are no telltale symptoms or non-invasive screening tools to catch a tumor before it spreads.

The app, BiliScreen, uses a smartphone camera Samson Ebukam Rams Jersey , computer vision algorithms and machine learning tools to detect increased bilirubin levels in a person's sclera, or the white part of the eye.

One of the earliest symptoms of pancreatic cancer, as well as other diseases, is jaundice, a yellow discoloration of the skin and eyes caused by a buildup of bilirubin in the blood. The blood test currently in use to measure bilirubin levels is typically not administered to adults unless there is reason for concern.

""The problem with pancreatic cancer is that by the time you're symptomatic, it's frequently too late Josh Reynolds Rams Jersey ,"" Alex Mariakakis, a doctoral student at UW's Paul G. Allen School of Computer Science & Engineering, was quoted as saying in a news release. The ability to detect signs of jaundice when bilirubin levels are minimally elevated could enable an entirely new screening program for at-risk individuals.

""The hope is that if people can do this simple test once a month - in the privacy of their own homes - some might catch the disease early enough to undergo treatment that could save their lives,"" explained Mariakakis, who as lead author of a paper will present the app at Ubicomp 2017, the Association for Computing Machinery's International Joint Conference on Pervasive and Ubiquitous Computing John Johnson Rams Jersey , in Maui, Hawaii, on September 13.

In adults, the whites of the eyes are more sensitive than skin to changes in bilirubin levels, which can be an early warning sign for pancreatic cancer, hepatitis or the generally harmless Gilbert's syndrome. Unlike skin color Cooper Kupp Rams Jersey , changes in the sclera are more consistent across all races and ethnicities. Yet by the time people notice the yellowish discoloration in the sclera, bilirubin levels are already well past cause for concern.

Wondering if computer vision and machine learning tools could detect those color changes in the eye before humans can see them, the UW team built BiliScreen on earlier work from the university's Ubiquitous Computing Lab, which previously developed BiliCam, a smartphone app that screens for newborn jaundice by taking a picture of a baby's skin. A recent study in the journal Pediatrics showed BiliCam provided accurate estimates of bilirubin levels in 530 infants.

The new app uses a smartphone's built-in camera and flash to collect pictures of a person's eye as they snap a selfie, then calculates the color information from the sclera and correlates it with bilirubin levels using machine learning algorithms.

To account for different lighting conditions Gerald Everett Rams Jersey , the team tested BiliScreen with two different accessories: paper glasses printed with colored squares to help calibrate color and a 3-D printed box that blocks out ambient lighting. Using the app with the box accessory led to slightly better results.

In an initial clinical study of 70 people, BiliScreen correctly identified cases of concern 89.7 percent of the time.

LUXEMBOURG, Aug. 29 (Xinhua) -- Hailing China's Belt and Road Initiative ""win-win"" Todd Gurley II Rams Jersey , Luxembourg Prime Minister Xavier Bettel has voiced his country's support for the initiative.

""Transport goes in both directions. It is these initiatives that make it possible to make win-win situations,"" Bettel told Xinhua in a recent interview.

Proposed by China in 2013, the Belt and Road Initiative aims to build trade and infrastructure networks connecting Asia with Europe and Africa along the ancient Silk Road trade routes.

Bettel made an official visit to China in June this year, one he said was fruitful.

""Four agreements were signed during the visit. The visit also allowed me to discover China. And it is also a visit that allowed me to see in the 45th anniversary of diplomatic relations between Luxembourg and China, a relationship of trust that exists,"" he said.

""What impressed me Rush Jamon Brown Jersey , for example, is China's leadership role, also in respect of COP21. When I was in China, it was just some time after (U.S.) President (Donald) Trump said he did not want to follow (the Paris Climate Accord),"" said the prime minister.

""We could have had a domino effect. And I met strong Chinese leaders, who want to defend the COP21 Rush Rob Havenstein Jersey , who want to continue to have a political responsibility that is not always 'popular' but necessary to preserve as future generations,"" he said.

Amid a rising protectionist tendency against Chinese investment in Europe, Bettel told Xinhua that the two sides ""have to agree to do something that will satisfy both parties, something that will benefit the one and the other, without it being at the cost of the other.""

""I think that the Sino-European cooperation must be a cooperation that works. We tend to stigmatize what is wrong and yet there are so many things that work. When you see the partnership between Europe and China, whether it's Luxembourg and China Rush Tyler Higbee Jersey , or Europe and China, we need each other,"" said the prime minister.<
