High dopamine transporter levels not linked to attention-deficit hyperactivity disorder

Results from a brain-imaging study conducted at the U.S. Department of Energy's Brookhaven National Laboratory in collaboration with Mount Sinai School of Medicine in New York indicate that levels of a brain protein proposed as a diagnostic marker for attention-deficit hyperactivity disorder (ADHD) are not positively correlated with the disease.

Test strips for the rapid detection of cocaine

Saving the life of a poisoning victim is often a matter of minutes. It is best when the emergency doctor can perform a reliable diagnosis on the spot to determine which poison or what type of drug overdose a patient is suffering from. Complicated laboratory analyses and a complex apparatus are out of place in the emergency room.
