The findings may explain how abstinence from these foods contributes to relapse eating among dieters as well as related eating disorders.

Yet, research suggests that fewer than half of pediatricians report screening patients for such at-risk behaviors. A new diagnostic test allows clinicians to quickly and accurately screen teens for high risk drug and alcohol use. Now, researchers have established that the same test can also identify teens who more likely to be engaging in high risk sexual behaviors.

As the changes occurred, the rats developed compulsive overeating habits -- and became obese. The overeating continued even when it meant the rats had to endure an unpleasant consequence (a mild foot shock) in order to consume the food.

This metabolic switch also has implications for the deadly liver disease cirrhosis in humans. A counterpart human gene contributes to a shift from metabolizing alcohol to the formation of fat in heavy drinkers. This shift can lead to fatty liver syndrome -- a precursor to cirrhosis.

Researchers have shown that the flow of calcium ions into brain cells via voltage-gated calcium channels plays an important role in the generation of alcohol withdrawal seizures, because blocking this flow suppresses these seizures. But do the changes in calcium currents contribute to alcohol withdrawal seizures or are they a consequence of the seizures?
