University of Illinois at Chicago researchers have found that a new treatment alternative for people suffering from severe asthma attacks is more effective and much less costly than traditional hospital inpatient care. Researchers estimate that the alternative treatment, known as an emergency department observation unit, costs $1,202 per patient compared with $2,247 per patient for inpatient care -- a drop of 47 percent.
The tiny worm that has become a darling of developmental biologists has revealed a biological function for a mysterious protein that may play a role in the growth of tumors. In the cover article of the April 1 Genes and Development, Yang Shi, HMS associate professor of pathology, reports that the worm's version of the human protein p300 helps cells in the early embryo decide what kind of tissue to become. Shi found that p300 also is critical for determining the number of cells formed in the embryo. His finding validates earlier cell culture experiments on how viral cancer-causing proteins subvert a cell's growth.
DALLAS, April 3 -- Women and certain other groups of patients who undergo carotid endarterectomy -- a common procedure used to clear blockages in the blood vessels to the brain -- may have a higher risk for death or stroke following the surgery, according to a study in this month's Stroke: Journal of the American Heart Association.

Ultrasound waves may be as effective as magnetic resonance imaging at detecting small blood vessel blockage after a heart attack, according to researchers at Johns Hopkins.
Patients with mutant p53 become resistant to treatment. In fact, the proliferating cells can develop other mutations and become more and more resistant. Sayed Daoud's approach is to focus on the p53 gene itself by using a combination of drugs, one to attack the tumor itself and one to inhibit the effect of the mutated p53. When the effect of the mutated p53 is inhibited, the cell usually will, as Daoud puts it, "crash and die."
Laboratory mice which have been genetically altered to produce human growth hormone grow to be 25-30 percent larger than normal mice---with much of that size difference coming from bigger bones, according to researchers.
