Scientists delete enzyme in mice so they can eat any type of fat and not get heart disease

A new study in mice raises a tantalizing possibility, that humans may one day be able to eat any kind of fat they want without raising their risk of heart disease.

Nitric oxide may be the key to why specific drugs for heart failure or asthma lose their effectiveness over time

A naturally occurring molecule in the body appears to control whether certain medications, such as beta adrenergic receptor agonists used in acute heart failure or in inhalers for asthma, lose their effectiveness over time.

Cause of gender differences in high blood pressure and related kidney disease

While men and women both get high blood pressure and related kidney disease, the path to get there is shorter, steeper and just different for men, researchers say.

Serious illness among children with sickle cell disease reduced with pneumococcal conjugate vaccine

A vaccine introduced in 2000 has reduced by more than 90 percent the rate of a serious bacterial illness among young children with sickle cell disease (SCD), who are particularly susceptible to it, according to a new study that appears in the June 1 issue of Clinical Infectious Diseases and currently is available online.

Variants of two genes involved in the inflammatory system linked to cognitive decline after heart surgery

Duke University Medical Center researchers believe their findings could help physicians identify patients at risk of suffering mental decline after heart surgery and raises the possibility that these patients could be treated with drugs that are known to dampen the inflammatory response.

Diesel exhaust fumes affect bone marrow blood flow

A new study finds that exposure to a chemical component of diesel exhaust particles can compromise the ability of resistance arteries to regulate blood flow to bone marrow.

Higher calcium and vitamin D intake linked to brain lesions in seniors

Elderly men and women who consumed higher levels of calcium and vitamin D are significantly more likely to have greater volumes of brain lesions, regions of damage that can increase risk of cognitive impairment, dementia, depression and stroke.

New class of nontoxic cancer treatments

A new class of compounds developed by two University of Kentucky researchers shows promise as a nontoxic treatment of some cancers previously treated with toxic chemotherapy, the researchers report today.

Silicone wires in newer defibrillators less reliable than older polyurethane-insulated leads

German researchers say the newer wire leads now used in implantable cardioverter defibrillators (ICDs) are not as reliable as first thought.

Simvastatin may help sufferers with Alzheimer's

Treatment with Simvastatin, one of the statin drugs widely used for lowering cholesterol in humans, significantly improved spatial memory - how to navigate a water maze - in mice genetically bred to have an Alzheimer's like disease.

Caution against over-aggressive use of erythropoiesis-stimulating agents for cancer-related anemia

Echoing recent FDA warnings, a research group from Northern Ireland cautions against over-aggressive use of a group of drugs called "erythropoiesis-stimulating agents" (ESAs) to treat anemia in some cancer patients, according to a commentary in the April issue of The Oncologist, published by AlphaMed Press.

Nanoparticles found near plaque-filled arteries

Scientific evidence increasingly links arterial calcification to the presence of nanosized particles so small that some scientists question whether a nanoparticle can live and, if so, play a viable role in causing disease.

Two-photon absorption imaging of hemoglobin

In an advance that can potentially assist cancer diagnosis, a new optical technique provides high-resolution, three-dimensional images of blood vessels by taking advantage of the natural multiple-photon-absorbing properties of hemoglobin, the red-blood-cell molecule that carries oxygen throughout the bloodstream.

Researchers identify antioxidant mechanisms involved in protection against heart disease

Zvonimir Katusic, M.D., Ph.D., and Mayo colleagues have identified antioxidant mechanisms essential for regenerative function of endothelial progenitor cells (EPCs).

Drug for toenail fungus also blocks angiogenesis

Researchers at Johns Hopkins have discovered to their surprise that a drug commonly used to treat toenail fungus can also block angiogenesis, the growth of new blood vessels commonly seen in cancers.

Headaches may act like tiny transient strokes

Migraines may be doing more than causing people skull-splitting pain. Scientists have found evidence that the headaches may also be acting like tiny transient strokes, leaving parts of the brain starved for oxygen and altering the brain in significant ways.
