Ferroelectric Switching Seen in Biological Tissues

June 24, 2014 12:57 pm | News | Comments

Researchers have shown that a favorable electrical property is present in a type of protein found in organs that repeatedly stretch and retract, such as the lungs, heart and arteries. These findings are the first that clearly track this phenomenon, called ferroelectricity, occurring at the molecular level in biological tissues.

Broken Gene Found to Protect Against Heart Disease

June 19, 2014 2:41 pm | News | Comments

By scouring the DNA of thousands of patients, researchers have discovered four rare gene mutations that not only lower the levels of triglycerides, a type of fat in the blood, but also significantly reduce a person’s risk of coronary heart disease—dropping it by 40 percent. The mutations all cripple the same gene, called APOC3, suggesting a powerful strategy in developing new drugs against heart disease.

Blood Test Identifies Heart-transplant Rejection Earlier than Biopsy Can

June 19, 2014 9:56 am | News | Comments

Stanford University researchers have devised a noninvasive way to detect heart-transplant rejection weeks or months earlier than previously possible. The test, which relies on the detection of increasing amounts of the donor’s DNA in the blood of the recipient, does not require the removal of any heart tissue.

Heart Rate Variability May Predict Risk of Disease in Premature Infants

June 13, 2014 1:34 pm | News | Comments

Measuring variability of heart rate may identify premature infants at risk of developing necrotizing enterocolitis, a serious inflammatory condition that can lead to death, according to Penn State College of Medicine researchers. Necrotizing enterocolitis, or NEC, may lead to destruction of the intestinal wall and vital organ failure. It affects 6 to 10 percent of premature infants within the first two weeks of life.
