HIV Patients May Be at Risk of Heart Problems When Taking Protease Inhibitor Drugs

...ed 24 cases of heart rhythm disturbances -- all of which were associated with protease inhibitors. They investigated the hypothesis that the widely-used protease inhibitors may, in fact, be linked to the development of heart rhythm problems through the mechanism of blocking a channel. Ultimately researche...

Combination therapy boosts effectiveness of telomere-directed cancer cell death

... cancer cells produce an enzyme,called telomerase, which prevents telomeres from getting too short socells can keep dividing. Telomerase is not used by healthy cells, andhas been identified as a logical target for anticancer therapeutics.However, recent studies indicate that for this therapy to be effectiv...
