... of the arteries," Dr. Schmidt says. "The arteries stiffen
and get blocked." When a blockage occurs, the cells lining the arteries produce nitric oxide to signal to the arterial muscles that they need to dilate the artery and allow more blood through. But free radicals destroy a key enzyme that allows the ...
Researchers show that veins stiffen as we age
...em in Newark has now confirmed that even our veins stiffen
as we age. "When you are young, your veins are nice and elastic--like rubber bands," William Farquhar, a cardiovascular physiologist in UD's College of Health Sciences, said. "But as you grow older, we've found that your veins become more like lead...
Swell gel could bring relief to back pain sufferers
...s have developed tiny gel particles that swell and stiffen
when injected into a damaged area. Investigations have revealed that degenerated animal intervertebral discs containing the injected 'microgels' regain their mechanical properties. This development opens up the possibility of human patients be...
Nanotechnology meets biology and DNA finds its groove

it by removing salts from its chemical makeup. But confining the molecule and presenting it for analysis is laborious, engaging armies of lab techs worldwide to prepare DNA samples for their moment in the lab. "To get DNA molecules to do this on s...
