A minority-owned small business in New York and the Department of Energy's Oak Ridge National Laboratory are uniting to harness the power of knowledge through the innovative Community of the Future Initiative.
Albany Medical College researchers have for the first time provided data that shows that the major predictor of resistance to AIDS drugs is whether the amount of virus in a patient's body has been reduced to nondetectable limits. The analysis showed that among the patients who received just Indinavir, those who were able to reduce the amount of virus in them to less than detectable levels had "significantly lower risks of emergence of resistance" to the drug. When combination therapy was used, such as a combined treatment of Indinavir, AZT, and 3TC, patients had significantly longer times to resistance compared to monotherapy patients even after adjusting statistically for the increased antiviral effect of the additional drugs.
A research team at Boston University School of Medicine has discovered that a synthetic compound significantly limits brain damage when administered after a stroke. Their finding, published September 16 in the Proceedings of the National Academy of Sciences, could lead to the development of drugs to treat stroke and traumatic brain or spinal cord injury. These new drugs could also slow the progression of ParkinsonÃs disease and ALS, more commonly known as ìLou GehrigÃs disease.î

Two diseases -- atherosclerosis and osteoporosis -- may be linked by a common problem in how the body uses calcium, according to two reports in American Heart Associations journals. One report is published in Stroke, the other is in today's Circulation.
Researchers have found a mutation in a fat-dissolving gene that raises the risk of heart attack by five-fold compared to individuals with a normal gene. Reporting in today's American Heart Association journal Circulation, they say the gene mutation may place 1 in 1,500 individuals at increased risk for heart attack.
Dr. David Furnas, Chief of the Department of Plastic Surgery at the University of California-Irvine Medical Center, will report tomorrow how the Digital Holographyô System from Voxelô (NASDAQ:VOXL) is helping plastic surgeons reshape congenitally malformed skulls. The holograms produced by the system have helped clinicians diagnose craniofacial problems, create pre-surgical plans, and intraoperatively measure and reconstruct these misshapened skulls.
Results from a Temple University Hospital study indicate that hyperbaric oxygen (HBO) therapy does not speed healing time for soft-tissue sports injuries. Although HBO therapy is becoming increasingly popular with professional sports teams, this study marks the first time it has been put to the scientific test.

A Johns Hopkins University professor has built a "virtual laboratory" on the World Wide Web to give engineering students a taste of the challenges they may someday face on the job.
Nearly 12 million children and adolescents are diagnosed with emotional disorders, including anxiety and depression, in the United States each year. Yet because the medications used to treat these disorders are tested mainly on adults, little is known about their safety and efficacy in children and adolescents. Now, a new National Institutes of Health research center at Columbia University's College of Physicians & Surgeons aims to correct that deficit.

A new form of matter, clusters of atoms, has been found to have a previously unsuspected property: it can melt at different temperatures from "solid" matter. An experiment described in Science this week paints an exotic portrait of certain substances seemingly confounding nature by existing as a liquid, instead of a solid, at room temperature.
Glaciers have been regarded as catalysts for the multiplication of species around the globe. Now, new research at the University of Minnesota casts doubt on this general theory and points to a more complicated evolutionary history for birds and other animals.

To find out, Johns Hopkins researchers are preparing a cargo of special cells to board the shuttle Atlantis for a 10-day trip including a stop at space station Mir. The shuttle is scheduled to launch from Cape Canaveral, Fla., on Sept. 25.
The tuberculosis vaccine known as BCG has been given to more people worldwide than any other vaccine, yet its effectiveness remains controversial. A new analysis by researchers at Stanford School of Medicine suggests that the bacterial strains used in current BCG vaccines have evolved in the laboratory and are now considerably weaker -- and less likely to provide protection from tuberculosis -- than the original vaccine developed about 75 years ago in France.

Whether you perm, straighten, style or just brush your hair, you're eroding its protective cuticle layer and, eventually, breaking hair strands. Now scientists have, for the first time, figured out the step-by-step chemical effect of hair relaxers on curly hair, leading to new uses for polymers to protect your hair.

People are always amazed at what they find in their attics, but the latest discovery is that dust in the attics of some older homes in Nevada and Utah contain trace amounts of radioactivity left over from above-ground nuclear testing northwest of Las Vegas in the 1940s and 1950s. The researchers stressed that the radioactivity is low enough that the dust poses no direct danger to area residents. Embargoed for 9-10-97, 1:00 PM EDT

If there is life on Mars, it won't include those insensitive men popularized in best-selling books and on talk shows, a Purdue University communication expert says. "The popular notion that men and women are from different planets so to speak ó and thus they have trouble communicating with each other ó is a fallacy," says Brant Burleson, professor of communication.
