Survival of heart patients on beta-blockers varies greatly with genetic variation

...rbances. "Long-term therapy with beta-blockers is standard care for heart patients," Lanfear says. "Data from patients with acute myocardial infarction have shown that beta-blockers are generally effective. They are known to decrease the size of the infarct and seem to prolong survival, on average." Recent ...

New Lab Research May Help Those Deafened By Immune System Attack

They urged women and men of all ages to take responsibility for their bone health, to recognize that while beauty is partly physical it is also made up of inner beauty that includes respecting one's he...

Neurologix announces positive results of gene therapy clinical trial in Parkinson's disease

.... Also, activities of daily living (ADL), another standard measure of Parkinson's severity which is recorded by the patients themselves, showed a strong trend toward statistical improvement(p= .06). In addition, fluorodeoxyglucose (FDG)-PET scans at one year revealed that the treated side of the brain exhib...

Opiates Better Than Sedatives For Treating Newborns In Withdrawal

For years, sedatives have been the gold standard for treating newborns suffering from opiate withdrawal. However, new research suggests that opiates themselves are superior to sedatives for treating infants born to women who used heroin or methadone while pregnant. Opiates appear to better "amelio...
