| Blood sugar control does not help infants and children undergoing heart surgery, study finds Posted: 08 Sep 2012 05:16 AM PDT Tight blood sugar control in infants and children undergoing heart surgery does not lower the risk of infection or improve recovery, according to a new study. |
| Surprising new roles for a key regulatory enzyme of blood pressure Posted: 08 Sep 2012 05:16 AM PDT Many patients with hypertension are treated with ACE inhibitors. These drugs block the angiotensin converting enzyme (ACE) that regulates the salt and water balance of the body and raises blood pressure. Recent studies, however, significantly broadened the enzyme's known task spectrum. |
| Skin and immune system influence salt storage and regulate blood pressure Posted: 08 Sep 2012 05:16 AM PDT High blood pressure is responsible for many cardiovascular diseases. High salt intake has long been considered a risk factor, but not every type of high blood pressure is associated with high salt intake. New findings now show that the skin and the immune system play an important role in the regulation of the sodium balance and hypertension, as he reported at a symposium in Berlin. |
| Posted: 08 Sep 2012 04:36 AM PDT As many as a quarter of U.S. Medicare recipients spend more than the total value of their assets on out-of-pocket health care expenses during the last five years of their lives, according to researchers. They found that 43 percent of Medicare recipients spend more than their total assets minus the value of their primary residences. |
| Tension on gut muscles induces cell invasion in zebrafish intestine, mimicking cancer metastasis Posted: 07 Sep 2012 01:06 PM PDT Towards a better understanding of how tissue stiffness drives cancer, researchers show that epithelial cells lining the intestine of zebrafish with a mutation of the smooth muscle myosin gene form protrusions called invadopodia that allow the cells to invade surrounding tissue. The protrusions form in response to contractions in surrounding smooth muscle cells. |
| Obstructive sleep apnea (OSA) increases cardiovascular mortality in the elderly Posted: 07 Sep 2012 04:18 AM PDT Untreated severe obstructive sleep apnea (OSA) is associated with an increased risk of cardiovascular mortality in the elderly, and adequate treatment with continuous positive airway pressure (CPAP) may significantly reduce this risk, according to a new study from researchers in Spain. |
