Gimli gobblers Mercury scientists to conduct unique human experiment next week
...ommunity-based research they're conducting. "Being guinea
pigs like this takes us back to our roots," says Dr. Lucotte. "It's important for us to remember that we're not just working on a hypothetical story, we're working with real people and real passions. And that we ourselves can be exposed to mercury in...
Acetaminophen shows positive in vivo cardioprotective effects in heart attack, arrhythmia
...urrent study was a follow up to earlier studies on guinea
pig hearts where one of the most pronounced effects was mechanical; acetaminophen aided the left ventricle during reperfusion. But in dogs, acetaminophen only affected the necrotic part of the heart. In other words, acetaminophen had no net beneficia...

...marily used literature knowledge from the foremost guinea
pig of genetics: the fruit fly. More is known about the details of the genetic network here than in humans. "In the fruit fly one can find almost 200 rules that are canalyzing, and this property is most likely general and applicable to genetic networ...
Purdue research offers hope for canine, human spinal injuries
