Tufts University researchers have identified proteins on the surface of cancer cells that contribute to the cells' ability to metastasize.

Social stress boosts immune system's flu-fighting abilities
A new study in mice suggests that, in certain cases, stress may enhance the body's ability to fight the flu.

In asthma, it's not the drugs but the inflammation that increases cardiovascular risk, damage
East Carolina University researchers discovered that the inflammation associated with asthma directly affects the heart's recovery from a heart attack, confirming growing evidence that asthma may directly, and negatively, impact the cardiovascular system.

'Mandela's Paradox' may show that osteoporosis propensity starts in pre-teen years
Halfway through a large 20-year study of South African youth, researchers discovered a counterintuitive finding that may lead to rethinking the development of osteoporosis, the roots of which may well lie in the childhood years.

Growth factor in baby formula could reduce NEC, most devastating GI disease in preemies
NEC incidence among breast-fed babies is a little as 10% of formula-fed.

Positive air pressure chamber started with patients quickly after surgery
Unique pressure chamber allows patients who have lower-extremity orthopaedic surgery to begin upright, normal gait rehabilitation very early post-surgically, something not usually possible in standard rehabilitation protocols using swimming pools, parallel bars, or walking devices.

Estrogen, SERMS reduce asthma impact by halting constriction
Medical College of Georgia scientists showed that elevated estrogen levels reduce the severity of asthma and perhaps of other diseases involving airway constriction.

Cranberry juice modulates atherosclerotic vascular dysfunction
Taking cranberry juice powder regularly over six months saw a pronounced improvement in vascular function - ability of blood vessels to relax - in subjects with high blood cholesterol and atherosclerosis, a University of Wisconsin-Madison School of Veterinary Medicine study found.

Pediatric burn victims' recovery, diabetes, metabolism aided by fenofibrate (Tricor)
Increasing cell fat metabolism with fenofibrate (Tricor) in seriously burned children also improved glucose metabolism to nearly normal levels, according to clinical work at University of Texas Medical Branch and Shriners Hospital for Children.

Alcohol 'binges' in rats during early brain development cause circadian rhythm problems
In a study believed to have implications for children and adults suffering from Fetal Alcohol Syndrome, rat pups given alcohol during a period of rapid brain development demonstrated significant changes in circadian or 24-hour rhythms as adults.

New study documents the detrimental impact of teen beverage choices
To combat the escalating rates of childhood obesity, parents should go beyond what's on their children's plate and look at what's filling their glass, suggests a new study that was presented today at the Experimental Biology scientific conference.
