Elevated antibodies to gluten proteins of wheat found in children with autism in comparison to those without autism. Results from a new study also indicated an association between the elevated antibodies and the presence of gastrointestinal symptoms in the affected children. They did not find any connection, however, between the elevated antibodies and celiac disease, an autoimmune disorder known to be triggered by gluten.

Scientists from the Florida campus of The Scripps Research Institute have found a compound that could counter Parkinson’s disease in two ways at once. In a new study published recently online ahead of print by the journal ACS Chemical Biology, the scientists describe a “dual inhibitor” that attacks a pair of proteins closely associated with development of Parkinson’s disease.

A combination of the myxoma virus and the immune suppressant rapamycin can kill glioblastoma multiforme, the most common and deadliest malignant brain tumor, according to Moffitt Cancer Center research. Peter A. Forsyth, M.D., of Moffitt’s Neuro-Oncology Program, says the combination has been shown to infect and kill both brain cancer stem cells and differentiated compartments of glioblastoma multiforme.

One in four people who survive a stroke or transient ischemic attack (TIA) suffer from symptoms of PTSD within the 1st year post-event, and one in nine experience chronic PTSD more than a year later. The data, e-published by PLOS ONE, suggest that each year nearly 300,000 stroke/TIA survivors will develop PTSD symptoms as a result of their health scare.

The role of dietary fructose in the development of obesity and fatty liver diseases remains controversial, with previous studies indicating that the problems resulted from fructose and a diet too high in calories. However, a new study conducted in an animal model at Wake Forest Baptist Medical Center showed that fructose rapidly caused liver damage even without weight gain. The researchers found that over the six-week study period liver damage more than doubled in the animals fed a high-fructose diet as compared to those in the control group.

Researchers at Moffitt Cancer Center and colleagues at Louisiana State University have developed a method for identifying aggressive prostate cancers that require immediate therapy. It relies on understanding the genetic interaction between single nucleotide polymorphisms (SNPs). The goal is to better predict a prostate cancer’s aggressiveness to avoid unnecessary radical treatment.
