Saving a penny: Stem cell therapy shows promise in repairing stress urinary incontinence Posted: 20 Aug 2012 05:50 PM PDT Stress urinary incontinence (SUI) can occur due to sneezing, coughing, exercising or even laughing and happens because the pelvic floor muscles are too weak causing leakage when the bladder is put under pressure. New research shows that a new technique, using stem cells isolated from amniotic fluid, can regenerate damaged urethral sphincter muscles and prevent pressure incontinence in mice. Although SUI is more common during and after pregnancy, and after the age of 40, one in three women will experience it at some point in their lives. Men can also be affected, especially after prostate surgery.

Evidence that new biomimetic controlled-release capsules may help in gum disease Posted: 20 Aug 2012 06:37 AM PDT Scientists are trying to open a new front in the battle against gum disease, the leading cause of tooth loss in adults and sometimes termed the most serious oral health problem of the 21st century. They have developed a new treatment approach.

Brain enzyme is double whammy for Alzheimer's disease Posted: 20 Aug 2012 06:37 AM PDT The underlying causes of Alzheimer's disease are not fully understood, but a good deal of evidence points to the accumulation of β-amyloid, a protein that's toxic to nerve cells. β-amyloid -- a toxic protein known to accumulate in the brains of most Alzheimer's disease patients -- is formed by several enzymes, including BACE1. Researchers have now found that BACE1 does more than just help produce β-amyloid -- it also regulates another cellular process that contributes to memory loss. This is important information for drug makers looking to target BACE1 to prevent or treat Alzheimer's disease.

Binge drinking college students are happier than their non-binge drinking peers, study suggests Posted: 20 Aug 2012 06:08 AM PDT Why do some colleges have persistently high levels of binge drinking? It may be because, at these schools, binge drinking is associated with high status and binge drinkers are happier with their college social experience than their non-binge drinking peers, suggests new research.

Secondhand smoke impairs vital cough reflex in kids Posted: 20 Aug 2012 06:08 AM PDT New research reveals that exposure to secondhand smoke decreases sensitivity to cough-eliciting respiratory irritants in healthy children and adolescents. The findings may help to explain why children of smokers are more likely to develop respiratory diseases and also are more likely to experiment with smoking during adolescence.

Weight-loss surgery results in positive changes in social life, medical conditions Posted: 19 Aug 2012 12:39 PM PDT New research shows that people who have bariatric surgery to treat obesity report an overall improvement in quality of life issues after surgery, from their relationships to their medical conditions.
