Wildfire Smoke Blankets Oregon, Triggering Air Quality Alerts and Excessive Heat Warnings

Originally Published 2 years ago — by KTVZ

The Oregon Department of Environmental Quality and Lane Regional Air Protection Agency have issued an air quality advisory for Deschutes, Lane, and Klamath counties due to thick smoke from wildfires, with much of the region experiencing "hazardous" levels. Intermittent smoke from other fires may also affect parts of Jackson, Josephine, eastern Douglas, and southeastern Linn counties. Smoke levels can change rapidly, and people are advised to stay indoors, keep windows and doors closed, and avoid strenuous outdoor activity. High-efficiency air filters or purifiers are recommended, while cloth and surgical masks are ineffective. N95 or P100 respirators may offer protection but should be properly selected and worn.

Breakthrough drug reduces bacteria's antibiotic resistance development.

Originally Published 2 years ago — by Medical Xpress

Researchers at Baylor College of Medicine have developed a drug called dequalinium chloride (DEQ) that significantly reduces the ability of bacteria to develop antibiotic resistance. The drug slows down the speed at which new mutations are formed in bacteria, which might prolong antibiotic effectiveness. The researchers screened 1,120 drugs approved for human use for their ability to dial down the master bacterial stress response, which they showed counters the emergence of resistance mutations. DEQ fulfilled both requirements and reduced the development of mutations that confer antibiotic resistance, both in laboratory cultures and in animal models of infection, and bacteria did not develop resistance to DEQ.
