In a study of nearly 2,000 adults, researchers found that a buildup of plaque in the body's major arteries was associated with mild cognitive impairment. Atherosclerosis is a condition in which fat, cholesterol and other substances collect in the arteries, forming a substance called plaque that can build up, limiting blood flow. It can occur in any artery of the body, including the carotid, which supplies blood to the brain, coronary arteries and the aorta, which carries oxygenated blood from the heart through the abdomen to the rest of body.

Nanoparticle designs target and treat early stage cancer cells by killing those cells with heat, delivered from inside the cell itself. Normal cells are thus left unaffected by the treatment regimen.

There wasn't a diagnostic capability to identify mild brain injury early after the trauma until recently. In the NFL, other professional sports and especially school sports, concern has grown about the long-term neuropsychiatric consequences of repeated mild Traumatic Brain Injury (mTBI) and specifically sports-related concussive and sub-concussive head impacts.'

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.
