The age at which an adolescent begins using marijuana may affect typical brain development, according to researchers at the Center for BrainHealth at The University of Texas at Dallas. In a paper recently published in Developmental Cognitive Neuroscience, scientists describe how marijuana use, and the age at which use is initiated, may adversely alter brain structures that underlie higher order thinking.
Researchers at The University of Texas at Austin have discovered that a type of cancer found primarily in children can grow only when signaled to do so by other nearby cells that are noncancerous.
Scientists at the Florida campus of The Scripps Research Institute have developed a device that can do the functional equivalent of high-throughput compound screening on an ultra-miniaturized scale.
For the first time, researchers have shown that computerized cognitive rehabilitation (a program to help brain-injured or otherwise cognitively impaired individuals to restore normal functioning) can improve attention and executive functioning in brain injury survivors including traumatic brain injury (TBI) and stroke.
St. Jude Children's Research Hospital investigators report that pediatric acute lymphoblastic leukemia patients from the contemporary treatment era remain at risk for attention and learning problems later.
Washington University School of Medicine researchers report an estimated 12.5 percent of adults living in the United States use marijuana, but their research also shows that the rate of pot use did not double from 2002 to 2013 -- as had been reported in the fall -- but instead increased by about 20 percent. Meanwhile, the rate of problems related to the drug has remained steady.
Patients who go to UPMC Presbyterian for heart catheterization and who receive a stent to treat clogged arteries are now being screened with a simple blood test to determine if they have a gene variant that makes them less likely to respond to a blood-thinning medication commonly prescribed after the procedure.
For most women, expecting a baby brings intense joy -- and a fair amount of worry. But what about women who have lived through something awful enough to cause post-traumatic stress disorder? Contrary to what researchers expected, a new study shows that pregnancy may actually reduce their PTSD symptoms. Or at the least, it won't cause a flare-up.
Alcohol itself can directly damage liver cells. Now researchers at University of California, San Diego School of Medicine report evidence that alcohol is also harmful to the liver for a second reason -- it allows gut bacteria to migrate to the liver, promoting alcohol-induced liver disease. The study, conducted in mice and in laboratory samples, is published Feb. 10 in Cell Host & Microbe.
By seeking the advice of patients, families and other stakeholders in designing a clinical trial investigating pediatric appendicitis, researchers found a way to significantly increase the number of people recruited and retained in the trial.
