University Of Kentucky One Of First To Use New Technique To Treat Atrial Flutter
... doctors could "turn off" any misfiring electrical circuits
and stop the atrial flutter. But in some patients -- particularly larger people with large hearts -- the heat failed to reach some deeply buried circuits, which allowed the atrial flutter to come back. In the experimental method used yesterday, t...

...ilicon age," said Lal, who believesthat integrated circuits
are only scraping the surface of the material'spotential. "It's the most perfect material you can find for the cost. Onesilicon wafer might cost $15 bucks, and it is practically flawlessstructurally." Silicon micro-machines -- also called micro-elect...
Coffee: a cause of neonatal seizures?
... as oxygenstarvation, adenosine protects the nerve circuits
from uncontrolled excitation,which can be detrimental. Caffeine takes the place of adenosine and prevents itfrom playing its normal role. This experiment illustrates the detrimental effects of caffeine present in thebrain of a hypoxic fetus. Caffei...

Animal model shows pain and tissue injury in newborns alters nerve circuitry and reaction to pain later in life
...ge in input had passed by day 14, so that neuronal circuits
