'Warrior Gene' Linked To Gang Membership, Weapon Use: FSU Study
Boys who carry a particular variation of the gene Monoamine oxidase A (MAOA), sometimes called the "warrior gene," are more likely not only to join gangs but also to be among the most violent members and to use weapons, according to a new study from The Florida State University that is the first to confirm an MAOA link specifically to gangs and guns.

Lantheus Medical Imaging, Inc. Completes Enrollment Of CaRES Registry To Further Evaluate Definity(R) In Patients With Suboptimal Echocardiograms
Lantheus Medical Imaging, Inc., a worldwide leader in diagnostic imaging, announces that it has completed patient enrollment of CaRES (Contrast Echocardiography REgistry for Safety Surveillance), the first, multicenter Phase IV observational registry that evaluates the use of ultrasound imaging agents in routine clinical practice. The 1,060 patients who were enrolled at 15 sites in the U.S. were 18 years old or older and required DEFINITY® Vial for (Perflutren Lipid Microsphere) injectable suspension-enhanced echocardiography because of a previous suboptimal, unenhanced echocardiogram.

Is Cancer The Price We Pay For Being Smarter Than Chimps?

Are the cognitively superior brains of humans, in part, responsible for our higher rates of cancer? That"s a question that has nagged at John McDonald, chair of Georgia Tech"s School of Biology and chief research scientist at the Ovarian Cancer Institute, for a while. Now, after an initial study, it seems that McDonald is on to something. The new study is available online in the journal Medical Hypothesis and will appear in the forthcoming issue of the journal. "I was always intrigued by the fact that chimpanzees appear to have lower rates of cancer than humans," said McDonald. "So we went back and reanalyzed some previously reported gene expression studies including data that were not used in the original analyses." McDonald and his graduate students, Gaurav Arora and Nalini Polivarapu, compared chimp-human gene expression patterns in five tissues: brain, testes, liver, kidneys and heart. They found distinct differences in the way apoptosis - or programmed cell death - operates, suggesting that humans do not "self-destroy" cells as effectively as chimpanzees do. Apoptosis is one of the primary mechanisms by which our bodies destroy cancer cells. "The results from our analysis suggest that humans aren"t as efficient as chimpanzees in carrying out programmed cell death. We believe this difference may have evolved as a way to increase brain size and associated cognitive ability in humans, but the cost could be an increased propensity for cancer," said McDonald. Like all evolutionary hypotheses, this can"t be proven absolutely, according to McDonald. However, his lab has recently obtained additional direct experimental evidence consistent with the hypothesis that apoptotic function is more efficient in chimps than in humans.
