Mammograms could more frequently bear good news if researchers develop an effective breast cancer vaccine.Progress toward development of a breast cancer vaccine has been reported by researchers at Washington University School of Medicine and the Siteman Cancer Center in St. Louis. Physicians believe a vaccine-induced immune response could be used to supplement other cancer therapies or to immunize high-risk people against cancer.

WUSM researchers have developed new risk estimates for premature babies.If a woman goes into labor before her baby is full term, her obstetrician must make a crucial recommendation: delay labor or allow it to continue. Delivering the baby prematurely may increase the risk of neonatal respiratory distress syndrome (RDS), a potentially fatal condition. Now medical researchers at Washington University in St. Louis have generated new risk estimates for RDS that allow physicians to make delivery decisions with far greater confidence.

Michael R. Brent and Tamara L. Doering examine data from the *C. neoformans* microarray.A team of collaborators, including two researchers from Washington University in St. Louis, has sequenced the genomes of two strains of the fungus Cryptococcus neoformans (C. neoformans), one which is virulent, the other harmless. This work provides researchers with clues on how the fungus does its dirty work and a host of genes to study for a better understanding of fungal pathogens in general. Estimates are that about 15 percent of people with HIV will suffer at least one life-threatening infection of C. neoformans. In Africa, that could be as much as 40 percent of HIV sufferers.

Rates of celiac disease are significantly higher in patients with osteoporosis, according to researchers at the School of Medicine. They recommend using blood tests to screen osteoporosis patients for celiac disease because their study has shown that treating celiac disease with diet can restore bone health in these patients.

*Arabidopsis thaliana*A team headed by Craig Pikaard, Ph.D., Washington University professor of biology in Arts & Sciences, has discovered a fourth kind of RNA polymerase found only in plants and speculated to have been a plant feature for more than 200 million years.

Researchers at WUSTL, Stanford University and Loyola University Medical Center, among others, used a first-of-its-kind statistical method.

About 19 percent of people have a genetic variation that may increase susceptibility to osteoporosis, a School of Medicine study says.

The research shows that the stroke-prevention drug Exanta is less cost-effective for most patients than the blood thinner warfarin.
