College eating habits can pack on extra pounds.College students talk about the “Freshman 15.” That’s the typical number of credit hours a full-time student takes during a semester. Some also claim it’s the number of pounds students gain eating dorm food and studying all night. New work from researchers at Washington University in St. Louis confirms that most students do, indeed, gain weight in college. Reporting in the Journal of American College Health, the research team found that about 70 percent of students gained a significant amount of weight between the start of college and the end of sophomore year.

Researchers are trying to reduce the number of pills needed by AIDS patients.The public perception of AIDS treatment — a cocktail of many different pills taken several times a day and sometimes even in the middle of the night — has largely been erased in the United States thanks to advances in drug design and delivery. Although textbook treatment guidelines still call for patients to take a few AIDS medications twice a day, many patients in industrialized countries are now able to keep sufficiently high medication levels in their bodies with once-daily doses. Now researchers in an international collaborative that includes the Aids Clinical Trials Unit (ACTU) at Washington University School of Medicine in St. Louis have begun an ambitious new study to see if this treatment paradigm can be implemented in Third World countries.

Outgrowth of nerve branchesA protein that helps the ends of growing nerve cells push forward is also involved in guidance of the nerve branches, according to a study by researchers at Washington University School of Medicine in St. Louis. They had believed that the protein, myosin II, was only a motor, but the new study shows it appears to help steer the nerve cells, too. By better understanding how nerve branches grow and move, the researchers hope one day to be able to regenerate injured nerves. They reported their findings in a recent issue of Nature Neuroscience.

Smoking can increase the risk of death from cervical cancer.Cervical cancer patients infected with either of two strains of human papillomavirus (HPV) were twice as likely to die of their disease as patients with other common strains of HPV, according to a study at Washington University School of Medicine in St. Louis. In addition, smokers with these strains increased their risk of death even further. Nearly all cervical cancers are associated with HPV infection of the cervix.

Anthony H. Guarino, M.D., instructor of anesthesiology, is joining scientists from around the country to test the drug called CC-5013.

Research has shown that the compound 17AAG has the unusual ability to simultaneously affect multiple proteins implicated in human cancers.

Researchers have found that the areas of the brain that young people use when daydreaming are the same areas that fail in people with Alzheimer’s.

Clint’s DNA was used to sequence the chimp genome.Comparing the human genome to the chimpanzee genome has allowed scientists to identify changes in the human genetic code that were so advantageous that they rapidly became the norm throughout humanity. The areas of human DNA where these changes occurred are currently the subject of follow-up investigations to identify the potentially vital contributions they now make to human health and development.

Deborah C. Rubin, M.D., has been named director of the Master of Arts and Doctor of Medicine Program (M.A./M.D.) at the School of Medicine.
