Researchers find evidence of mature heart cell potential in embryonic stem cells

In a new study, UC Davis researchers report the first functional evidence that heart cells derived from human embryonic stem cells exhibit one of the most critical properties of mature adult heart cells, an important biological process called excitation-contraction coupling.

Study may aid pancreatic cancer patients' response to chemo drugs

Pancreatic cancer patients face the worst survival rates compared to all other forms of human cancer as the disease is nearly impossible to diagnose at an early stage when successful treatments might be possible.

Study explains why physical activity is beneficial in preventing heart attack and stroke

It is well known that physical activity can improve cardiovascular health. But it's the impact exercise has on specific known risk factors that accounts for about 60 percent of that improvement, researchers reported in Circulation: Journal of the American Heart Association.

Researchers create modular, multi-functional drug delivery system

There are two aspects to creating an effective drug: finding a chemical compound that has the desired biological effect and minimal side-effects and then delivering it to the right place in the body for it to do its job.

AKAP18 protein helps heart beat faster

A protein, known as AKAP18, could help the heart to beat faster in response to adrenaline or noradrenaline, according to a study published online this week in EMBO reports.

Enzyme's second messenger contributes to cell overgrowth

Scientists at the University of California, San Diego (UCSD) School of Medicine have uncovered a novel pathway by which hormones elevated in inflammation, cancer and cell injury act on cells to stimulate their growth.

Process of necrosis redefined in landmark study

A new study led by investigators from the University of Pittsburgh School of Medicine demonstrates that the process of necrosis, long thought to be a chaotic, irreversible pathway to cell death, may actually be triggered as part of a regulated response to stress by a powerful protein, SRP-6, that can potentially halt necrosis in its path.

A chink in bacteria's armor

Biomedical researchers at Boston University's College of Engineering may have discovered the path toward developing better drugs capable of defeating so-called “superbugs,” bacteria that have developed resistance to common antibiotics. The researchers have discovered a previously unknown chain of events occurring in bacteria that opens to door to new avenues of research.

A drug-sensitive 'traffic cop' tells potassium channels to get lost

Our brains are buzzing with electrical activity created by sodium and potassium ions moving in and out of neurons through specialized pores. To prevent the constant chatter from descending into chaos the activity of these ion channels has to be tightly regulated.

Skin-healing pseudoceramides

Researchers report in the September 2007 issue of the Journal of Lipid Research that they have made synthetic lipids called pseudoceramides that are involved in skin cell growth and could be used in treating skin diseases in which skin cells grow abnormally.
