Little is known about mitral valve surgical outcomes within the largest US federal health system -- the Veterans Administration Health System. New data presented from 40 VA cardiac surgery centers reveal that although MV repair rates increased from 48 percent in 2001 to 63 percent in 2013, a wide…

Research has demonstrated a positive correlation between fitness and blood flow to areas of the brain where the hallmark tangles and plaques of Alzheimer's disease (AD) pathology are usually first detected, indicating a possibility that regular exercise could stave off AD symptoms.

Statins could protect the hearts of babies in the womb from the adverse effects of their mother's stress, research suggests. The therapy could lower the chances of babies being born underweight and reduce their risk of health problems in later life, including heart disease, researchers say.

Horseradish contains cancer-fighting compounds known as glucosinolates. Glucosinolate type and quantity vary depending on size and quality of the horseradish root. For the first time, the activation of cancer-fighting enzymes by glucosinolate products in horseradish has been documented.

Researchers have developed a technique for imaging brain activity in a freely walking fruit fly. Working with one of the most common model organisms in science, the team shows for the first time what goes on in the brain of the fly during courtship -- when it's unrestrained.

A new study randomly assigned 448 preterm infants born between 26 weeks 0 days' and 31 weeks 6 days' gestation to receive either high-dose recombinant human erythropoietin (rhEPO) or placebo (saline) intravenously within 3 hours, at 12 to 18 hours, and at 36 to 42 hours after birth.

Researchers have identified an enzyme that is significantly elevated in mouse models of systemic lupus erythematosus and in blood samples of patients with lupus. The new findings demonstrate that inhibition of the SHP-2 enzyme can significantly diminish lupus symptoms – including skin lesions,…

Chronic fatigue syndrome patients report they are more anxious and distressed than people who don't have the condition, and they are also more likely to suppress those emotions. In addition, when under stress, they show greater activation of the biological "fight or flight" mechanism, which may add…

An international team of researchers has unraveled a new regulatory mechanism how food components and environmental factors influence the immune system. Various substances present in the intestines can bind to an important controller, the Ah receptor. This system is in turn regulated by the Ah…

A new study shows that compared to non-shift workers, shift workers needed more time to complete a test that is frequently used by physicians to screen for cognitive impairment. However, those who had quit shift work more than five years ago completed the test just as quick as the non-shift workers.

Surgeons in Japan have developed a technique to relieve airway obstruction in children. The technique, known as external stenting (ES), expands and stabilizes the airway by suspending its wall to a rigid prosthesis placed around the bronchus or trachea. ES avoids the problem of granulation…
