After three weeks ?more than two months before the final MRI scan ?researchers found significant differences between the patients' scans. Some areas reflected an increase in water diffus...

Protein Packages Found To Activate Genes; May Be What Regulates Development And Disease

...vered with tags. This was not seen before by using standard techniques, or by studying one gene at a time. "Finding them was a complete surprise," Bernstein admits. HOX genes, as noted, play vital roles in embryo development. Understanding how they are regulated should help researchers determine the molecule...

Gene Therapy For Parkinson's Disease Moves Forward In Animals

...Parkinson's disease. Levodopa, considered the gold standard of current treatment, enables the brain to replenish its dwindling supply of dopamine, sidetracking the destructive course of Parkinson's disease.
