Multiple characteristics of HAART affect adherence

Pill count has the greatest impact on adherence, survey reports

The total number of pills that need to be taken every day in HAART therapy has the greatest impact on adherence of 10 characteristics studied, according to a survey of HIV positive individuals, nearly two-thirds of whom had experienced at least three treatment regimens. The findings of the Perspectives on Adherence and Simplicity for HIV+ Patients on Antiretroviral Therapy (PASPORT) survey were presented here today at the

New type of antiobiotic tackles hard-to-treat pediatric infections

Pediatricians have another weapon in their arsenal to fight infections that have shown resistance to common antibiotics, according to data presented today by a team of investigators led by Baylor College of Medicine.

Study results showed that linezolid, a new type of antibiotic, is well-tolerated and as effective as the most common antibiotic, vancomycin, in treating infants and children with known or suspected gram-positive infections, reported Dr. Sheldon Kaplan, Baylor professor of

Glucocorticoid use increases risk of spinal fractures

Among postmenopausal women, glucocorticoid users six times more likely to fracture

Daily dosing with oral glucocorticoids (corticosteroids) for chronic diseases was found to be a strong predictor of spinal fracture at one year, according to new data presented at the annual scientific meeting of the American College of Rheumatology (ACR). The risk of fracture was found to increase incrementally with every 1 mg increase above 7.5 mg in the daily dose of the glucocorticoid.

Bacterial protein kills tumors

New weapon in the fight against cancer?

The use of live bacteria to treat cancer goes back a hundred years. But while the therapy can sometimes shrink tumors, the treatment usually leads to toxicity, limiting its value in medicine.

Now, researchers at the University of Illinois at Chicago have isolated a protein secreted by bacteria that kills cancer cells but appears to have no harmful side effects. Tested in mice injected with human melanomas, the protein shrank the maligna

Scientists studying two big craters on earth find two causes

Two of the three largest impact craters on Earth have nearly the same size and structure, researchers say, but one was caused by a comet while the other was caused by an asteroid. These surprising results could have implications for where scientists might look for evidence of primitive life on Mars.

Susan Kieffer of the University of Illinois at Urbana-Champaign, Kevin Pope of Geo Eco Arc Research and Doreen Ames of Natural Resources Canada analyzed the structure and stratigraphy of the 65 m

Tiny plant poised to yield big payoffs in environment and energy

With the genomes of humans and several insects, animals and crop plants mapped or sequenced, biologists are turning their attention to single-celled algae no thicker than a human hair. Among the possible payoffs: crops requiring less fertilizer, a source of renewable energy and a new source for novel proteins.

The algae, Chlamydomonas reinhardtii , already are an important biological model for genetics research. Now, the complete genome of the plant’s chloroplast has been sequenced
