COLLEGE PARK, Md. — A team of neuroscientists has discovered important new information in the search for an effective treatment for Alzheimer’s disease, the debilitating neurological disorder that afflicts more than 5.3 million Americans and is the sixth-leading cause of death in the United States. Hey-Kyoung Lee , associate professor in the University of Maryland Department of Biology, and her research team have shown that they may be able to eliminate debilitating side effects caused by a promising Alzheimer’s drug by stimulating the brain’s nicotine receptors.

COLLEGE PARK, Md. — A research team including University of Maryland chemistry and biochemistry Professor Lyle Isaacs and University of Massachusetts Amherst chemist Vincent Rotello has demonstrated that they can deliver a dormant toxin into a specific site such as a tumor for anti-cancer therapy, then chemically trigger the toxin to de-cloak and attack from within. It holds promise as a complex and sophisticated synthetic, therapeutic drug delivery system for living cells. (more…)

*MU scientist compares classical singing to traditional Indian singing to find speech disorder treatment*

COLUMBIA, Mo. – Hindustani singing, a North Indian traditional style of singing, and classical singing, such as the music of Puccini, Mozart and Wagner, vary greatly in technique and sound. Now, speech-language pathology researchers at the University of Missouri are comparing the two styles in hopes of finding a treatment for laryngeal tremors, a vocal disorder associated with many neurological disorders that can result in severe communication difficulties.
