Mouse model paves way for lung cancer studies

Lung tumors from mutant mice show an abundance of abnormal, undifferentiated cells.Often mice are used to investigate cancer because their accelerated life spans allow discoveries to be made in a few months. But most strains of mice stay relatively free of lung tumors, even when exposed to heavy tobacco smoke, so there has been a shortage of models suitable for studying tobacco smoke-induced lung cancer. Now, cancer researchers at Washington University School of Medicine in St. Louis have developed a strain of mice that readily develops lung tumors that have the same genetic mutations found in human lung tumors.

Device traps, disables harmful bacteria

A team of engineers from Washington University in St. Louis and the University of Colorado at Boulder has removed bioaerosols – airborne biological particulate matter — from the air of a hospital therapy pool using a new generation of hybrid filters. The bioaerosols identified in the unnamed Midwestern hospital pool had sickened nine lifeguards who had become ill with hypersensitivity pneumonitis, a lung condition that mimics pneumonia symptoms. This forced the pool to shut down. It is now reopened.

Veterans of first Gulf War have more chronic fatigue, fibromyalgia

U.S. Army photoThe battles don’t end with the war for some soldiers.More than a decade after the first Gulf War in 1991, a detailed comparison of the health of veterans who were deployed to the Persian Gulf region and veterans who served elsewhere has found that the health of the two groups is very similar. However, the study also found that Gulf War veterans are more likely to have chronic fatigue syndrome and fibromyalgia syndrome.

New asthma drug holds hope for some

A new medication can reduce emergency room visits and improve the overall quality of life for moderate to severe asthma sufferers, according to a study by researchers from the School of Medicine and St. Louis University. Learn more about the new drug in the following St. Louis Post-Dispatch story.
