Bacteria that cause tooth decay able to survive without important biochemical pathway

...eneral to be a "silent epidemic," tooth decay is a chronic childhood disease that affects five times more children than asthma and is estimated to result in 51 million lost school hours. In an effort to understand how best to combat the tooth-decaying properties of S. mutans, Brady and her team set out to l...

Scientists show how thinking can harm brain cells

...chanism by which brain cells can be damaged during chronic neurodegenerative diseases. When inflammation occurs in the brain, nerve impulses that are passed between cells during routine activities like learning and memory can become toxic. Instead of triggering the formation of memories, these impulses can i...

Texas scientists discover how a hepatitis C protein promotes liver cancer

...oximately 200 million people worldwide suffer from chronic hepatitis C, which can persist in the body for decades after an initial infection, often causing so much liver damage that a transplant may be a patient's only chance for survival. The most effective treatment available, interferon therapy, works onl...
