Like cleaning the lenses of a foggy pair of glasses, scientists are now able to use a technique developed by UCLA researchers and their European colleagues to produce three-dimensional images of breast tissue that are two to three times sharper than those made using current CT scanners at hospitals. The technique also uses a lower dose of X-ray radiation than a mammogram.

These higher-quality images could allow breast tumors to be detected earlier and with much greater accuracy. One in eight women in the United States will be diagnosed with breast cancer during her lifetime.

The research is published the week of Oct. 22 in the early edition of the journal Proceedings of the National Academy of Sciences. (more…)

Medication Beliefs Strongly Affect Individuals’ Management of Chronic Diseases, MU Expert Says

Health practitioners should use behavior-change tactics so patients take medications as prescribed

COLUMBIA, Mo. – Nearly half of patients taking medications for chronic conditions do not strictly follow their prescribed medication regimens. Failure to use medications as directed increases patients’ risk for side effects, hospitalizations, reduced quality of life and shortened lifespans. Now, a University of Missouri gerontological nursing expert says patients’ poor adherence to prescribed medication regimens is connected to their beliefs about the necessity of prescriptions and concerns about long-term effects and dependency.

MU Assistant Professor Todd Ruppar found that patients’ beliefs about the causes of high blood pressure and the effectiveness of treatment alternatives significantly affected their likelihood of faithfully following prescribed medication regimens. In his pilot study, Ruppar focused on older patients’ adherence to medication treatments that control high blood pressure, a condition that affects nearly 70 million adults in the U.S. and can lead to heart disease and stroke.

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…)

Mutation Breaks HIV’s Resistance to Drugs, Says MU Researcher

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…)

Scientists Use PET to Predict Increased Survival in Cancer Patients After First Chemo Cycle

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…)

Nurses Key in Helping New Cancer Patients Overcome Fears

EAST LANSING, Mich. — Often faced with overwhelming anxiety, patients newly diagnosed with lung cancer can find themselves in distress, and new research recommends nurses play a key role in alleviating concerns, leading to a better quality of life for patients.

A diagnosis of lung cancer – the leading cause of cancer death in the United States – brings with it high levels of stress and raises existential issues and death-related thoughts and concerns in patients, said Rebecca H. Lehto, assistant professor in the College of Nursing at Michigan State University. (more…)

New Ability To Regrow Blood Vessels Holds Promise For Treatment of Heart Disease

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…)

Treatment For TB Can Be Guided By Patients’ Genetics

A gene that influences the inflammatory response to infection may also predict the effectiveness of drug treatment for a deadly form of tuberculosis.

An international collaboration between researchers at the University of Washington in Seattle, Duke University, Harvard University, the Oxford University Clinical Research Unit in Vietnam and Kings College London reported these findings Feb. 3 in the journal Cell. (more…)
