...y balloon in the artery to help clear the blockage responsible for the problem. But even when the blockage is cleared, it returns in 40% of cases.// Scientists believe the new technique of putting therapeutic genes into large numbers of cells in the artery wall could prevent such relapses. However, they warn t...

Mystery of nacrolepsy uncovered

Research on HIV takes new direction

...pecifically, they target the "Rev" protein that is responsible for producing and spreading HIV-infected cells. Without this protein, viral cells would be unable to reproduce and the disease would be disarmed, Tor said. By working with the virus's genetics, the researchers have found a place less prone to mutatio...

Brain Cell Repair Loss disclosed

...th, this meant internal programming was not wholly responsible an outside signal somehow had to activate a switch inside the neurons to make them stop growing. The researchers found the signal originates from neural circuits elsewhere in the retina known as amacrime cells. "They've showed there is a development...

Brain defect may play role in stammering
