School of Medicine scientists have identified a master gene involved in orchestrating the regrowth of peripheral nerves — the nerves that extend from the spinal column to the hands and feet and have the ability to regenerate and help people regain some movement and sensation. Understanding how these nerves regenerate may aid efforts to regrow spinal cord neurons.

New research suggests that patients whose mobility has been limited by stroke may one day use their imagination and a computer link to move their hands.

Neurons that have been infected with West Nile Virus.The cold winter is over, and spring rains and warmer weather mean that mosquito season is coming. Since 1999, summer mosquitoes have meant a risk for West Nile Virus. No one knows what 2004 will bring, but the season seems to have started early. The Centers for Disease Control and Prevention (CDC) already is reporting the presence of the virus in mosquitoes, birds and other animals in nine states. There even is confirmation of a human case in Ohio. Infectious diseases specialists at Washington University School of Medicine in St. Louis remind that the people at greatest risk are those 50 and older and those with weakened immune systems. Younger people also can acquire the infection, but their risk is significantly lower.
