Physicians from 60 sites treated 161 heart attack patients with their own bone marrow cells, selected for their healing potential and then reinjected into the heart, in an effort to improve the heart's recovery. Their conclusion? Patients who receive more cells get significant benefits.

Researchers have developed a hybrid metal-polymer nanoparticle that lights up in the acidic environment surrounding tumor cells. Nonspecific probes that can identify any kind of tumor are extremely useful for monitoring the location and spread of cancer and the effects of treatment, as well as aiding initial diagnosis.

Chemists have developed new nanoparticles that can simultaneously perform magnetic resonance imaging and fluorescent imaging in animals. Such particles could help scientists to track specific molecules produced in the body, monitor a tumor's environment, or determine whether drugs have successfully reached their targets.

Radiologists have issued a special report on radiology preparedness for handling cases of Ebola virus. Healthcare administrators are placing a major emphasis on Ebola preparedness training at medical facilities throughout the U.S. Failure to have proper procedures in place to diagnose and treat patients with Ebola virus was cited as a major reason for infection of medical personnel in Dallas.

The layer of fat that surrounds the heart may be a better predictor of atrial fibrillation than body mass index, the most common measure of obesity, a study has found. Obesity is commonly measured as a person’s body mass index (BMI). But a new study has found that the layer of fat around the outside of the heart is more closely associated with atrial fibrillation than BMI.

Fragile X syndrome (FXS) is the most common cause of inherited intellectual disability (ID), as well as the most frequent monogenic cause of autism spectrum disorders (ASD). FXS is caused by the absence or incorrect production of the protein FMRP. Scientists have now pinpointed a novel role that FMRP plays during the embryonic development of the brain cortex.

Routine heart imaging screenings for people with diabetes at high risk to experience a cardiac event, but who have no symptoms of heart disease, does not help them avoid heart attacks, hospitalization for unstable angina or cardiac death, according to a major new study.

A fluorescence imaging technique has been developed that can more accurately identify receptors for targeted cancer therapies without a tissue biopsy. "Accurately determining the population of protein receptors in a tumor available for targeting by molecular therapies or diagnostic imaging agents can greatly impact oncology patient outcomes," said one investigator. "Our in vivo receptor concentration imaging technique is a novel approach for fluorescence imaging that can potentially impact clinical assessment of tumor status and malignant tissue classification."
