UD alumnus one of Popular Science magazine’s ‘Brilliant 10’ Young Scientists
University of Delaware alumnus Deva Ramanan has been named one of Popular Science magazine’s “Brilliant 10” Young Scientists.
The designation places Ramanan on the magazine’s annual “honor roll” of the 10 most promising scientist for 2012.
Ramanan, who earned his bachelor’s degree in computer engineering at UD in 2000, is an associate professor of computer science at the University of California Irvine (UCI). There he is working to improve a computer’s image recognition capability, or in simpler terms, a computer’s ability to “see people.” (more…)
Doctors can improve treatment programs using this knowledge
COLUMBIA, Mo. – The human immunodeficiency virus (HIV) can contain dozens of different mutations, called polymorphisms. In a recent study an international team of researchers, including University of Missouri scientists, found that one of those mutations, called 172K, made certain forms of the virus more susceptible to treatment. Soon, doctors will be able to use this knowledge to improve the drug regimen they prescribe to HIV-infected individuals.
“The 172K polymorphism makes certain forms of HIV less resistant to drugs,” said Stefan Sarafianos, corresponding author of the study and a researcher at MU’s Bond Life Sciences Center. “172K doesn’t affect the virus’ normal activities. In some varieties of HIV that have developed resistance to drugs, when the 172K mutation is present, resistance to two classes of anti-HIV drugs is suppressed. We estimate up to 3 percent of HIV strains carry the 172K polymorphism.” (more…)
Researchers from UCLA’s Jonsson Comprehensive Cancer Center have found that by administering a PET scan to individuals with soft-tissue sarcomas after just a single cycle of neoadjuvant chemotherapy, they can predict increased survival in these patients.
Prior research by this multidisciplinary team of physician-scientists had shown that a combined PET/CT scan using a glucose uptake probe called FDG allowed them to determine the pathologic response of patients’ tumors after the first dose of chemotherapy drugs. They then wondered if the patients who showed a significant PET response after the first round of chemotherapy also were surviving longer. (more…)
AUSTIN, Texas — University of Texas at Austin researchers have demonstrated a new and more effective method for regrowing blood vessels in the heart and limbs — a research advancement that could have major implications for how we treat heart disease, the leading cause of death in the Western world.
The treatment method developed by Cockrell School of Engineering Assistant Professor Aaron Baker could allow doctors to bypass surgery and instead repair damaged blood vessels simply by injecting a lipid-incased substance into a patient. Once inside the body, the substance stimulates cell growth and spurs the growth of new blood vessels from pre-existing ones. (more…)
*According to a new analysis of hundreds of recorded office visits, doctors and nurse practitioners typically issued orders and asked closed or leading questions when talking to their HIV-positive patients about adherence to antiretroviral therapy. Attempts at problem-solving with patients who had lapsed occurred in less than a quarter of visits.*
PROVIDENCE, R.I. [Brown University] — Take your medicine, Doctor’s orders. It’s a simple idea that may seem especially obvious when the pills are the antiretroviral (ARV) drugs that add decades to the lives of HIV-positive patients. But despite the reality that keeping up with drug regimens is not easy for many patients, a new analysis of hundreds of recorded doctor’s office visits finds that physicians and nurse practitioners often still rely on lecturing, ordering, and scolding rather than listening and problem solving with their patients.

GAINESVILLE, Fla. — Taking an unauthorized photo of a patient and posting it on Facebook is a giant no-no for health-care providers, who follow strict federal guidelines protecting patient privacy.
But what if the patient is a little girl in Ecuador receiving a vaccine from an American medical student, who’s in the country on a medical outreach trip? Although taking photos of patients in developing countries and posting them on the Web may not be illegal, it’s not ethical, say researchers from the University of Florida.
It’s long been a common practice for health care providers to snap photos while volunteering their time in developing countries, generally to bring back evidence of the conditions patients face there. But reporting in the Journal of Medical Internet Research, UF College of Medicine researchers say providers should treat patients’ privacy with the same reverence no matter where the care takes place.
