Does nitric oxide buffer arterial blood pressure variability in humans?

Animal studies suggest that nitric oxide (NO) plays an important role in buffering short-term arterial pressure variability, but data from humans addressing this hypothesis are scarce. We evaluated the effects of NO synthase (NOS) inhibition on arterial blood pressure (BP) variability in eight healthy subjects in the supine position and during 60 degrees head-up tilt (HUT). Systemic NOS was blo...

Speed does matter in reading

A s a director of a university diagnostic reading clinic, I see children of all ages who, for one reason or another, are making poor progress in learning to read. Our job in the reading clinic is to determine the nature and source of the child’s reading problem and suggest (and implement) instructional interventions for helping the child improve. Often the children we see in our clinic demonstr...

Debate: does it matter how you lower blood pressure?

The evidence base for drug treatment of hypertension is strong. Early trials using thiazide diuretics suggested a shortfall in prevention of coronary heart disease. The superiority of newer drugs has been widely advocated but trial evidence does not support an advantage of beta-blockers, angiotensin converting enzyme inhibitors, calcium channel blockers or alpha-blockers for this outcome. Even ...
