Discovery of gene mutation that appears to help prevent heart disease

Researchers at the University of Maryland School of Medicine in Baltimore have discovered a novel gene mutation among the Old Order Amish population that significantly reduces the level of triglycerides in the blood and appears to help prevent cardiovascular disease.

Humble toothbrush helps stop ventilator-associated pneumonia

Hospital-borne infections are a serious risk of a long-term hospital stay, and ventilator-associated pneumonia (VAP), a lung infection that develops in about 15% of all people who are ventilated, is among the most dangerous.

Numbing drugs can have profound and long-term negative effects

A large proteomics study on the brains of newborn mice provides more evidence that numbing drugs often used in obstetric or pediatric medicine can have profound and long-term negative effects, even after minimal exposure.

Study shows major pain research funding decline at NIH

Federal funding for pain research is declining sharply, more than 9 percent a year since 2003, according to a new study published in The Journal of Pain.

Stressed-out mice reveal role of epigenetics in behavior

Research conducted by a team in Switzerland suggests that a family of genes involved in regulating the expression of other genes in the brain is responsible for helping us deal with external inputs such as stress.

Researchers find tamoxifen's power comes from endoxifen

Mayo Clinic researchers have discovered that a chemical known as endoxifen appears to be the primary metabolite responsible for the effectiveness of tamoxifen in treating breast cancer, and that it works against cancer in an entirely unexpected way.

Food you eat can immediately impact cognitive behavior

A new study from the psychology department at Tufts University shows that when dieters eliminate carbohydrates from their meals, they performed more poorly on memory-based tasks than when they reduce calories, but maintain carbohydrates.

Heart regenerates after infarction

Up until today scientists assumed that the adult heart is unable to regenerate. Now, researchers and cardiologists from the Max Delbrück Center for Molecular Medicine (MDC) Berlin-Buch and the Charité - Universitätsmedizin Berlin (Germany) have been able to show that this dogma no longer holds true.

Exercise suppresses appetite by affecting appetite hormones

A vigorous 60-minute workout on a treadmill affects the release of two key appetite hormones, ghrelin and peptide YY, while 90 minutes of weight lifting affects the level of only ghrelin, according to a new study.

Enzyme that mutates antibodies also targets cancer-causing gene

The human immune system is in a perpetual state of self-experimentation. It expertly mutates and shuffles the DNA of its own cells to evolve new defenses against the vast array of microbes that try to invade our bodies.

Enzyme that mutates antibodies also targets a cancer-causing oncogene

Rockefeller University scientists have discovered that the same enzyme that enables the immune system's defensive creativity is also responsible for a particular genetic malfunction - a translocation of one piece of DNA to the wrong chromosome - that causes Burkitt's lymphoma.
