Viruses may be linked to lung cancer

LOUISVILLE, Ky. (UPI) -- U.S. and Israeli researchers suggest viruses may have a role in the development of lung cancer.
The researchers all agree smoking is by far the most important risk factor for lung cancer, but Dr. Arash Resazadeh and colleagues from the University of Louisville, Ky., found five out of 22 non-small-cell lung cancer samples tested positive for human papilloma virus.

"We think HPV has a role as a co-carcinogen which increases the risk of cancer in a smoking population," Resasadeh said in a statement.

In another study, Samuel Ariad from Soroka Medical Center in Beer Sheva, Israel, and colleagues found more than half of the 65 patients with non-small-cell lung cancer had evidence of measles virus in tissue samples taken from their cancer.

In his study, Ariad found the "measles virus is a ubiquitous human virus that may be involved in the pathogenesis of lung cancer. Most likely, it acts in modifying the effect of other carcinogens and not as a causative f…

Brain disease studied at the atomic level

COLUMBUS, Ohio (UPI) -- U.S. scientists say they have, for the first time, inspected the atomic level of the protein that causes hereditary cerebral amyloid angiopathy.

The disease, thought to cause stroke and dementia, is initiated by certain kinds of proteins called prions that produce degenerative brain diseases such as CAA, mad cow disease and Creutzfeldt-Jakob disease in humans. All are incurable and fatal.

The researchers, led by Ohio State University Assistant Professor Christopher Jaroniec, used solid-state nuclear magnetic resonance spectroscopy to inspect a tiny portion of the protein molecule that is key to the formation of plaques in blood vessels in the brain.

"This is a very basic study of the structure of the protein and hopefully it will give other researchers the information they need to perform further studies and improve our understanding of CAA," he said.

The research that included doctoral students Jonathan Helmus and Philippe Naudaud, as well as scientists …

Migraines' Frequency Influences Heart Attack, Stoke Risk

THURSDAY, April 17 (HealthDay News) -- Women who have weekly migraines are at an increased risk for stroke compared to those with few or no migraines, a new study finds.

On the other hand, those with less frequent migraines may have an increased risk of heart attack, the same team of researchers report. The findings, to be presented Thursday at the American Academy of Neurology annual meeting in Chicago, point to different mechanisms linking migrain…
