The Chinese Ministry of Agriculture has halted operations at a national testing center for genetically modified organisms (GMOs) after investigators found the center in violation of management rules during its preparations for a qualification review by the ministry last year.
The ministry said in a post on its website Thursday that it probed into the alleged fabrication of documents at the center reported by Hao Jingliang Wholesale Minnesota Wild Jersey , a former doctoral student, on Zhihu, and discovered violations by the center in their preparation of materials, archive management and employment of personnel.
The ministry made a decision to suspend the center's operation and allow a six-month grace period to make corrections and improvements Wholesale Los Angeles Kings Jersey , and to revoke its qualification certificate if it fails to meet standards by the end of the grace period.
Meanwhile, the Chinese Academy of Agricultural Sciences was told to seriously punish those responsible for the violations.
The Beijing-based center for safety supervision, inspection and testing of transgenetic animals and feed, better known as the national test center for GMOs Wholesale Florida Panthers Jersey , was built based on resources at the Institute of Animal Sciences (Chinese Academy of Agricultural Sciences).
The center was accredited as a ministerial-level transgenetic inspection and testing agency for GM animals and feed, to ensure that they were environmentally safe.
From July 20 to 22, 2015, the ministry sent an expert panel to review the center's qualifications. To be fully prepared Wholesale Edmonton Oilers Jersey , from May to July, a few months ahead of the inspection, the center made up for missing archives that ranged from personnel training to usage of materials and devices, as well as meeting minutes Wholesale Detroit Red Wings Jersey , investigators found.
Also, during the 2015 review, four graduate students were hired to serve as the center's inspectors and archivists. Some of the testing tasks during an on-the-spot review session were carried out by graduate students in the name of the center's inspectors, which violated rules of personnel management Wholesale Dallas Stars Jersey , the ministry said.
However, the ministry did not find any fabrications in the testing processes or data.
The ministry said it only entrusted the center to conduct two experimental testing tasks in December 2011, and that the center carried out both indoor and outdoor tests according to a plan passed by experts. It issued reports in October 2015, which were backed by records of testing processes and data Wholesale Columbus Blue Jackets Jersey , therefore there were no fabrication problems, the ministry explained. However, the center did not give the original records to archivists for further management, it was added.
So far Wholesale Colorado Avalanche Jersey , the center has never issued any testing reports on GM products that have been granted safety certificates, the ministry said.
SAN FRANCISCO， May 19 (Xinhua) -- Researchers at Stanford University have designed a home urine test that uses a black box and a smartphone camera to help analyze a standard medical dipstick.
The dipstick test， or color-changing paper test， was invented to test blood sugar in 1956. It now involves a paper strip with 10 square pads. Dipped in a sample， each pad changes color to screen for the presence of a different disease-indicating chemical.
After waiting the appropriate amount of time， a medical professional or， increasingly an automated system， compares the pad shades to a color reference chart for results.
The test seems simple， but do-it-yourself systems on the market can be error prone， said Audrey Bowden， assistant professor of electrical engineering at Stanford. "You think it's easy -- you just dip the stick in urine and look for the color change， but there are things that can go wrong. Doctors don't end up trusting those results as accurate."
Considering the dipstick as a given， Bowden and Gennifer Smith， a PhD student in electrical engineering， designed a system to overcome three main potential errors in a home test: lighting， volume control and timing.
As a color-based test， the dipstick needs consistent lighting conditions. The same color can look different depending on its background， so Smith and Bowden created a black box that covers the dipstick. Its flat， interlocking parts make it easy to mail， store and assemble.
They tackled volume control. "If you have too little or too much urine on the dipstick， you'll get erroneous results，" Smith said. To fix this， they designed a multi-layered system to load urine onto the dipstick. A dropper squeezes urine into a hole in the first layer， filling up a channel in the second layer and ten square holes in the third layer. When the third layer is inserted into the black box， a uniform volume of urine is deposited on each of the ten pads at just the right time.
Then， a smartphone is placed on top of the black box with the video camera focused on the dipstick inside the box. Custom software reads video from the smartphone and controls the timing and color analysis.
To perform the test， a user would load the urine and then push the third layer into the box. When the third layer hits the back of the box， it signals the phone to begin the video recording at the precise moment when the urine is deposited on the pads.
Timing is critical to the analysis. Pads have readout times ranging from 30 seconds to 2 minutes. Once the two minutes are up， the user can transfer the recording to a software program on their computer. For each pad， it pulls out the frames from the correct time and reads out the results.
Writing in Lab on a Chip， a journal of the Royal Society of Chemistry， the researchers said they would like to design an app that would do the analysis on the phone and then send results directly to the doctor.
