FDA causes unnecessary scare about common painkillers

...r results ?that Voltaren was estimated to increase vascular risk by about 70 percent over Aleve. "Naproxen does not increase the risk of heart attacks and ought to be a painkiller of choice," said Furberg. "On the other hand, Voltaren carries the same risk as the harmful COX-2 inhibitors Bextra® and Vioxx®...

Blame the brain for high blood pressure

... blood pressure ?hypertension ? is an inflammatory vascular disease of the brain. One in three people in the UK are likely to develop hypertension, and with 600 million people affected world wide, it is of pandemic proportions.

Researchers identify ovarian cancer biomarkers

...there, they were able to determine which genes the vascular cells expressed. The results identified more than 70 markers that were present in large amounts in the blood vessels of cancer tissue but not in the vessels of normal tissues. The researchers went on to study in detail 12 markers that had not pr...

Mice with a migraine show signs of brain damage

...ras with their migraines are at increased risk for vascular problems like heart attack and stroke. The Women’s Health Initiative, for instance, found that such women had a 50 to 70 percent higher risk of stroke compared to other women. And a study led by Michel Ferrari of Leiden University in the Netherlands ...
