Stroke victims have new hope with activated protein C

...roke by preventing apoptosis, a form of programmed cell death. The study has shown// that APC reduced apoptosis by 65 per cent and neurological deficits by 91 per cent when given to mice following a stroke. Currently, only tissue plasminogen activator is useful for the 80 per cent of strokes that involve ...

Lead researcher David Adelson, said that for the study patients are cooled within six hours of injury. The researchers said that children are be...

Scientists locate key hormone involved in appetite control

... neurons. They then used tiny electrodes to record cell activity in response to ghrelin. The researchers have also located a new source for ghrelin production in the body. The site is located in a section of the hypothalamus that had no previously known function and that is near the brain region affected ...

New hope for spinal cord injury victims

Researchers from// the Loyola University in Chicago are now focusing the studies upon cells called olfactory ensheathing cells (OECs). OECs are the cells that form a sheath around t...

Scientists have discovered that some people with inherited DCM show a subtle mutation in their phospholamban gene. Patients with DCM may suffer with tiredness, and shortness of breath whilst exercising or even whilst res...

New genital gel could empower women against the AIDS epidemic

In the new study, researchers used a human antibody called b12 that binds an HIV coat protein and stops it latching onto cells. They found that when this product was used in monkeys two hours before sex, it preven...
