EGFR gums up cell's miRNA-processing machinery under oxygen starvation conditions

Even while being dragged to its destruction inside a cell, a cancer-promoting growth factor receptor fires away, sending signals that thwart the development of tumor-suppressing microRNAs before it's dissolved, researchers reported in an early online publication at Nature.

Discarded neutrophils release stem cells from bone marrow into bloodstream

CNIC researchers have discovered that the daily clearance of neutrophils from the body stimulates the release of hematopoietic stem cells from the bone marrow into the bloodstream, according to a report published today in the journal Cell.

Ongoing clinical study to evaluate benefits of high-dose simvastatin for patients with SAH

Can treatment with high doses of a cholesterol-lowering statin drug improve outcomes for patients with stroke caused by rupture and bleeding of brain aneurysms? An ongoing clinical trial will soon find out, according to an article in the May issue of Neurosurgery, official journal of the Congress of Neurological Surgeons.

Early-life exposure to traffic-related air pollution associated with higher hyperactivity

Early-life exposure to traffic-related air pollution was significantly associated with higher hyperactivity scores at age 7, according to new research from the University of Cincinnati (UC) and Cincinnati Children's Hospital Medical Center.

Kidneys discarded for transplant can be used for manufacturing replacement organs, say researchers

Nearly 20 percent of kidneys that are recovered from deceased donors in the U.S. are refused for transplant due to factors ranging from scarring in small blood vessels of the kidney's filtering units to the organ going too long without blood or oxygen. But, what if instead of being discarded, these organs could be "recycled" to help solve the critical shortage of donor organs?

Researchers examine new zinc-based bioabsorbable stents

In 2012, more than 3 million people had stents inserted in their coronary arteries. These tiny mesh tubes prop open blood vessels healing from procedures like a balloon angioplasty, which widens arteries blocked by clots or plaque deposits. After about six months, most damaged arteries are healed and stay open on their own. The stent, however, is there for a lifetime.

New research reveals how endothelium maintains highly efficient barrier function

The endothelium, the cellular layer lining the body's blood vessels, is extremely resilient. Measuring just a few hundred nanometers in thickness, this super-tenuous structure routinely withstands blood flow, hydrostatic pressure, stretch and tissue compression to create a unique and highly dynamic barrier that maintains the organization necessary to partition tissues from the body's circulatory system.

Nutritional supplement may improve survival rates of babies born with heart defects

A common nutritional supplement may be part of the magic in improving the survival rates of babies born with heart defects, researchers report. Carnitine, a compound that helps transport fat inside the cell powerhouse where it can be used for energy production, is currently used for purposes ranging from weight loss to chest pain.
