Metoprolol reduces cerebral tissue oxygen tension after acute hemodilution in rats.

30 Oct 2009 BACKGROUND: Perioperative beta-blockade and anemia are independent predictors of increased stroke and mortality by undefined mechanisms. This study investigated the effect of beta-blockade on cerebral tissue oxygen delivery in an experimental model ... Read more...

Retrograde viral vector-mediated inhibition of pontospinal noradrenergic neurons causes hyperalgesia in rats.

12 Oct 2009 Pontospinal noradrenergic neurons form a component of an endogenous analgesic system and represent a potential therapeutic target. We tested the principle that genetic manipulation of their excitability can alter nociception using an adenoviral ... Read more...

Global disturbances in autonomic function yield cardiovascular instability and hypertension in the chromogranin a null mouse.

7 Oct 2009 We reported previously that chromogranin A (Chga) knockout (KO) mice are hypertensive and hyperadrenergic. Here we sought to determine the basis of such alterations by probing physiological, biochemical, and pharmacological responses to ... Read more...
