American physicians may be too liberal in their use of blood transfusions

In an analysis of some 24,000 patient records, the researchers found that Americans rushed to the hospital with heart attack symptoms have significantly higher rates of bleeding and transfusions after treatment than similar patients throughout the world.

Drug pravastatin may provide a previously unknown cardiovascular benefit

The drug pravastatin, which is used widely to decrease high cholesterol, may provide a previously unknown cardiovascular benefit in addition to lowering lipids.

Six gene variants predict heart muscle damage after cardiac surgery

Duke University Medical Center researchers have found that patients with six specific variants of genes involved in the body's immune response are significantly more likely to suffer damage of heart tissue after cardiac surgery.

Biologically engineered blood vessels now an option in cardiac bypass

The first-ever human use of completely biologically engineered blood vessels grown from a person's own cells could be an option for people who have vessels too damaged for heart bypass, researchers reported at the American Heart Association's Scientific Sessions 2005.

Link between eating and pain relief - brain stem blocks pain to protect key behaviors

Certain behaviors, such as eating, drinking and urinating, are so crucial to survival that the brains of all vertebrates contain clusters of nerve cells that can suppress pain long enough to allow the animal to eat, drink - or pee - in peace.

Good fitness levels may extend the lives of women with metabolic syndrome

A high level of fitness may extend the lives of women with metabolic syndrome, according to new findings presented today by a cardiologist at Northwestern Memorial Hospital at the annual American Heart Association Scientific Sessions.

Early changes in the oxygenation of the skin may help predict foot disease in diabetes patients

Foot ulcerations are one of the most serious complications of diabetes, resulting in more than 80,000 lower-leg amputations each year in the U.S. alone.

Protein discovery may have implications for treating E. coli 0157:H7 infection

A discovery by Queen's researchers of a previously unknown protein may open the door to more effective treatment of a deadly strain of the E. coli bacteria.

University of Alberta researchers pioneer gene therapy to restore alveoli and lung capillaries in damaged rat lungs

The good news is that medical advances in perinatal care have allowed us to save many more premature babies. The bad news is they're often at risk of developing bronchopulmonary dysplasia--a chronic lung disease caused by having to place the tiny infants on ventilators and oxygen-rich therapy for acute respiratory failure.

New understanding of the disease process involved in atherosclerosis

The progression of the artery-clogging disease atherosclerosis is linked to the inability of specialized bone marrow cells to continuously repair damage to the arterial lining, Duke University Medical Center researchers have demonstrated.

Lifelong exercise decreases cellular aging in the brain

In the first study to show that lifelong exercise decreases cellular aging in the brain, scientists from the McKnight Brain Institute of the University of Florida say that moderately active rats have healthier DNA and more robust brain cells than their less active counterparts. The research was presented at the Society for Neuroscience's 35th annual meeting in Washington, D.C.

Cellular signal may determine life or death for damaged brain cells

Scientists at the Universities of Heidelberg and Ulm and a unit of the European Molecular Biology Laboratory (EMBL) in Monterotondo, Italy, have discovered that a specific signal within brain cells may determine whether they live or die after a stroke.

Human umbilical cord blood cells may widen treatment window for stroke

An experimental treatment that spares disability from acute stroke may be delivered much later than the current three-hour treatment standard – a potential advance needed to benefit more stroke victims.

First clinical study of FX06 treatment against damage caused by heart attacks

Central to the study is FXO6, a peptide developed and patented by Austro-American company Fibrex Medical. Fibrex will now test the tolerability and pharmacokinetics of FX06 in humans. The peptide reduces inflammatory responses of the heart muscle that can arise after treatment for a myocardial infarction. Tests will begin immediately on the first - healthy - subjects at the Vienna General Hospital.

Anti-aging hormone called Klotho actions explained

Scientists recently discovered an anti-aging hormone called Klotho. Now, a new study shows that this protein acts by increasing the cell's ability to detoxify harmful reactive oxygen species.

Bumetanide may help treat seizures in newborns

A diuretic drug called bumetanide may serendipitously help treat seizures in newborns, which are difficult to control with existing anticonvulsants, according to a study in the November Nature Medicine.

Cardiac regeneration using stem cells may heal hearts even years after heart attacks

Left ventricular function and exercise capacity increased, while the area of heart muscle damage shrank, in 18 patients given infusions of their own bone marrow stem cells up to eight years after a heart attack, according to a new study in the Nov. 1, 2005, issue of the Journal of the American College of Cardiology.
