These deposits indicate the onset of atherosclerosis, or so-called hardening of the arteries, and can be detected years before a person experiences chest pain or has a heart a...ADHD appears to be associated with depressed dopamine activity in the brain
...Brain scans were performed using positron emission tomography (PET) and a drug known as raclopride labeled with carbon 11 ([11C]raclopride), which binds with dopamine receptors. Scans were performed twice, after injections of placebo and of methylphenidate; the participants did not know which drug they had rece...Study shows radiofrequency ablation highly effective in treating kidney tumors
