Shutting off blood supply to extremity to protect heart

Posted: 24 Oct 2014 07:12 AM PDT

Shutting off the blood supply to an arm or leg before cardiac surgery protects the heart during the operation, a study shows. "The heart muscle of the patients who had restricted blood flow to their arm before surgery were able to maintain the same level of energy production during the whole operation, while heart muscle from the other patients' hearts was not. This may be important because heart tissue is dependent on energy to survive, as well as to repair injuries the cells may have endured during surgery," an investigator says.

High-dose vitamin D not effective for helping women with repeat reproductive tract infections

Posted: 24 Oct 2014 07:12 AM PDT

Vitamin D appears not to be effective for treating repeat occurrences of bacterial vaginosis (BV), the most common reproductive infection among women worldwide. While earlier studies have shown a correlation between low vitamin D levels and BV, new research shows the difficult-to-treat and frequently symptom-free reproductive infection isn't altered by high dose vitamin D supplements.

Pleasure of learning new words

Posted: 24 Oct 2014 05:25 AM PDT

From our very first years, we are intrinsically motivated to learn new words and their meanings.
