Study finds possible treatment strategy for Feingold syndrome type 1

A decrease in protein synthesis in cells of the developing gut contributes to a rare genetic disorder, and an inexpensive nutritional supplement may help reverse that decrease, according to a new study publishing November 1st in the open access journal PLOS Biology by Yun-Fei Li of Zhejiang University School of Medicine in Hangzhou, China, and colleagues. The finding is an advance in understanding the pathogenesis of the disease, and may lead to new treatments.

Study helps understand how dietary therapies work for epilepsy

Calorie restriction has long been associated with reduced seizures in epilepsy. New research from Boston Children's Hospital helps explain how fasting affects neurons in the brain and could lead the way to new approaches that would avoid the need for fasting or restrictive diets. The findings were published August 30 in the journal Cell Reports.
