Brain Scans May Help Diagnose

1 Autistic Brains Shaped Differently

Identifying kids with autism may be easier in the future after research shows that autistic brains have a unique shape compared to typically developing brains. CNN reports that researchers found significant differences in brain areas known as Default Mode Network, structures associated with self-awareness and social communication. The research, published in Biological Psychiatry, reveals that more severe cases of autism are tied with greater differences in brain structure. Researchers used new algorithms to analyze the data from MRI scans. They found that the algorithms are about 90 percent accurate for correctly identifying autism, but they can't identify autism in a real-world setting.

Recipient Could Also Be Donor

2 Cultured RBCs from Stem Cells Live in Patient

Paris researchers have proven that hematopoietic stem cells (HSCs) incubated with growth factors to make them differentiate into RBCs mature and survive in the body. They showed that cultured red blood cells (cRBCs) matured in the body by injecting them into four mice. Then the HSCs from a donor were incubated and the cRBCs put back into the donor. Five days later, 94 to 100 percent of the circulating cRBCs were still alive and by 26 days it was 41 to 63 percent. These numbers are comparable to the normal lifespan and survival of RBCs that have matured in the bone marrow before entering the bloodstream. Researchers believe once the technique is improved upon, this alternative will be a solution to the worldwide RBC shortage and the side effects of current blood transfusions reduced.
