BPA Stimulates Growth of Breast Cancer Cells, Diminishes Effect of Treatment

Bisphenol A (BPA), a chemical commonly used in plastics, appears to increase the proliferation of breast cancer cells, according to Duke Medicine researchers presenting at an annual meeting of endocrine scientists.

Air Pollution Controls Linked to Lower Death Rates in North Carolina

National and state air pollution controls that went into effect in the early 1990s coincide with decreasing death rates from emphysema, asthma and pneumonia among people in North Carolina, according to a study led by Duke University researchers.

Architecture of Signaling Proteins Enhances Knowledge of Key Receptors

A team of scientists from Duke Medicine, the University of Michigan and Stanford University has determined the underlying architecture of a cellular signaling complex involved in the body’s response to stimuli such as light and pain.

$15 Million Award to Go Toward Exploring New Treatments for Autism, Other Brain Disorders

Duke Medicine has been awarded $15 million to support an innovative research program that explores the use of umbilical cord blood cells to treat autism, stroke, cerebral palsy and related brain disorders.

Combining Treatments Boosts Some Smokers’ Ability to Quit

Combining two smoking cessation therapies is more effective than using just one for male and highly nicotine-dependent smokers who weren't initially helped by the nicotine patch, according to researchers at Duke Medicine.

Heparin Derivative Suppresses Neuroblastoma Tumor Growth

Researchers at Duke Medicine have identified a new strategy for treating neuroblastoma using a modified version of heparin, a century-old injectable drug that thins the blood to prevent clots from forming.

Lifetime Cancer Risk from Heart Imaging Low for Most Children, but Rises with More Complex Tests

Children with heart disease are exposed to low levels of radiation during X-rays, which do not significantly raise their lifetime cancer risk. However, children who undergo repeated complex imaging tests that deliver higher doses of radiation may have a slightly increased lifetime risk of cancer, according to researchers at Duke Medicine.

New Diagnostic Imaging Techniques Deemed Safe in Simulations

Gamma and neutron imaging offer possible improvements over existing techniques such as X-ray or CT, but their safety is not yet fully understood. Using computer simulations, imaging the liver and breast with gamma or neutron radiation was found to be safe, delivering levels of radiation on par with conventional medical imaging, according to researchers at Duke Medicine.

Registry for Fatal Lung Disease Aims to Speed Improvements in Care

Duke Clinical Research Institute (DCRI) has launched a patient registry to help researchers and clinicians identify, manage and study people who have a progressive lung disease called idiopathic pulmonary fibrosis.

One and Done: New Antibiotic Could Provide Single-Dose Option

In the battle against stubborn skin infections, including methicillin-resistant Staphylococcus aureus (MRSA), a new single-dose antibiotic is as effective as a twice-daily infusion given for up to 10 days, according to a large study led by Duke Medicine researchers.
