Water: the unexpected blood pressure drug

... 60 minutes caused the blood pressure effect to be sustained for another hour. In older normal subjects, the average increase in blood pressure was 11 millimeters of mercury. There is something about the water itself that causes the increase in blood pressure; intravenous infusion of 16 ounces of sugar solutio...

UF researcher develops high blood pressure drug using gene therapy technique

...ike all medication, when we begin to think about a sustained effect we have to wonder what happens if you block the receptors (with the antisense) for too long -- are there downsides to it? For example, what happens if you need the receptors to kick in under certain conditions?" Dzau said. "That being said, we...

...t of research at Cell Pathways. "We believe that a sustained rise in cGMP levels, in response to outside signals telling the cell that it is time to die, is blunted by high cGMP-PDE activity in neoplastic cells. If cGMP does not rise, PKG is not activated and the pathway culminating in apoptosis is blocked." ...
