If some patients with heart disease don’t take their doctor’s advice to quit smoking, they are probably going to get “shocking” reminders. A study conducted at Washington University School of Medicine in St. Louis found that heart patients who had implanted defibrillators and also smoked were seven times more likely to have the devices jolt their hearts back into normal rhythm than nonsmokers with the devices.

Bob Boston/WUSTL PhotoTwo surgeons at the same hospital perform the same operations on patients with similar medical histories. Their costs to the hospital are similar, right? Not necessarily. There could be a difference as high as 45 percent. New research from Washington University in St. Louis finds that even when controlling for complexity of the operation and patient risk, surgeons incurred a wide range of hospital costs. More…

Olga Pontes & Craig PikaardThe protein HDA6 shows up as a red stain in this Arabidopsis leaf cell nucleus.A team of researchers, including biologists at Washington University in St. Louis, has discovered the key role one protein plays in a major turn-off — in this case, the turning off of thousands of nearly identical genes in a hybrid plant. Studying the phenomenon of nucleolar dominance, in which one parental set of ribosomal genes in a hybrid is silenced, Craig Pikaard, Ph.D., Washington University professor of biology in Arts & Sciences and colleagues have identified the protein HDA6 as an important player in the silencing.

Elvin-Lewis has written a chapter in a new book that is critical of the unregulated U.S. herbal trade.Ginsengs, echinaceas, and ephedras, oh my! These herbs sound innocuous enough, however, according to Memory Elvin-Lewis, Ph.D., professor of microbiology and ethnobotany in biomedicine in Arts & Sciences at Washington University in St. Louis, Americans are unaware of the dangers inherent in these herbal supplements.

Static electricity buildup from sliding down a plastic slide — instant summertime fun for those with normal hearing — can temporarily silence the world to cochlear implantees. Two electrical engineers at Washington University in St. Louis tested static electricity buildup — which can zap a cochlear implant — on sliding children to quantify the sparks. Thanks to some publicity and increased awareness, their research has inspired the St. Louis County Parks and Recreation Department to consider the problem, and an anti-static coating company to try to solve it.

Researchers at the School of Medicine have found that obese elderly people can improve their physical function and lessen frailty by losing weight and exercising.

Researchers seeking insights into kidney failure in human infants have located the source of a 30-year-old mystery mutation that causes similar problems in a mouse line.

“When colleagues have professed great satisfaction about being a part of this community, it validates what we are doing,” Chancellor Wrighton said.

Researchers discovered that fibulin-4 causes a novel form of recessive cutis laxa, a disorder that results in severe connective tissues abnormalities.
