Aug. 16 (UPI) -- A study out Wednesday by a team of U.S. and German researchers has found that genetic variants affect how much gene expression changes in response to disease.The study, published in Nature Communications, involved researchers analyzing blood from 134 volunteers, and treated monocytes, or white blood cells, in the laboratory with three components to simulate infection with bacteria or virus."Our defense mechanisms against microbial pathogens rely on white blood cells that are specialized to detect infection. Upon encounter of microbes, these cells trigger cellular defense programs via activating and repressing the expression of hundreds of genes," said Dr. Veit Hornung of the Ludwig-Maxmilians-Universität in Munich, formerly from the University of Bonn.Researchers analyzed
Aug. 12 (UPI) -- The Ministry of Defense said Saturday the advanced U.S. missile defense system deployed in a southern town won't cause any adverse effects to the local environment.Earlier in the day, the defense and environment ministries conducted their joint environmental survey of electromagnetic radiation and noise from the Terminal High Altitude Area Defense system in Seongju, southeast of Seoul.Two rocket launchers and a powerful X-band radar are operational at the new U.S. Forces Korea base, formerly a private golf course.The defense ministry said the radiation level at a spot 100 meters from the radar was measured at 0.01659 watt per square meter on average during a six-minute test. From 500 meters away, it was 0.004136 W/㎡. At 700 meters from the radar, the radiation level was 0.
