Snapin: A protein with therapy potential for autism

Rutgers' Bonnie Firestein likens nerve cells to trees -- some are short and bushy with many branches while others are tall with a few branches coming out of one or two main trunks. Different branching patterns correlate with specific disorders and Firestein's quest is to discover how these dissimilar patterns come about and why. more

Transmission of Hepatitis C among family members

The prevalence of antibodies to Hepatitis C Virus (HCV) in Egypt is among the highest in the world. From the 1950s until 1982 hundreds of thousands were infected during mass campaigns to control schistosomiasis (a parasitic disease) using mass therapy with intravenous antimony compounds, but little is known about current risk factors and rates of transmission. Studies of high risk populations, such as intravenous drug users, shed little light on HCV transmission in Egypt where this high risk behavior is rare. more

Thinking the pain away? Study shows the brain's painkillers may cause 'placebo effect'  

Just thinking that a medicine will relieve pain is enough to prompt the brain to release its own natural painkillers, and soothe painful sensations, a new University of Michigan study finds. The study provides the first direct evidence that the brain's own pain-fighting chemicals, called endorphins, play a role in the phenomenon known as the placebo effect -- and that this response corresponds with a reduction in feelings of pain. more

Diagnostic strategy may help determine stage of lung cancer more accurately 

A preoperative testing strategy combining two procedures may help improve the accuracy of determining the stage of lung cancer, according to an article in the August 24/31 issue of JAMA. more

Long-term aspirin use reduces risk for colorectal cancer

A new report from the Nurse's Health Study finds that regular, long-term aspirin use can significantly reduce the risk of colorectal cancer, as suggested by several earlier studies. However, the benefit appears to require more than a decade and is strongest at dose levels associated with a greater risk of side effects such as bleeding. Similar results were found for non-steroidal anti-inflammatory drugs (NSAIDS) such as ibuprofen and naproxen. more
