Inventing new techniques along the way, the team is changing emergency room guidelines, building the foundation for earlier diagnosis of post-trauma organ failure and making possible the ...

Brain protein improves stroke symptoms in rats, even when injected after 3 days

...n effective stroke drug. A study in rats published today in the open access journal BMC Biology shows that an injection of Granulocyte-Colony Stimulating Factor (G-CSF), whose function in the brain is to control the formation of neurons and counteract neurone death, reduces the size of the area affected by...

Brains can recover from alcoholic damage but patients should stop drinking as soon as possible

The findings, published today (18 December 2006) in the online edition of the journal Brain [1], used sophisticated scanning technology and computer software to measure how brain volume, form and function changed over six to seven weeks of abstinence from alcohol in 15 alcohol de...
