Genetic factors in smoking also increase risk of chronic bronchitis

Smoking is a known risk factor for respiratory diseases like chronic bronchitis, but genes also play a significant role in its development, according to researchers in Sweden, who studied more than 40,000 Swedish twins to determine the extent to which behavior, environment and genes each play a role ion the development of chronic bronchitis.

New vaccine technology decreases E. coli in beef cattle

Despite millions of dollars spent on food safety research over the last 10 years, ground beef recalls due to E. coli O157:H7 were higher in 2007 than in 2006, according to researchers from Kansas State University and West Texas A&M University. E. coli O157:H7 has been linked to foodborne illnesses in humans after consuming contaminated beef and produce.

Genetic mutation linked to peripheral artery disease

The finding, appearing online in the journal Circulation, is the first to document a genetic mutation linked to PAD. Although the work was done in mice, researchers say it is likely to give them new insight into how PAD develops and progresses in humans.
