New research shows that while these muscle cells are responsible for constricting or dilating the blood vessels, they are not responsible for sensing the amount of oxygen that gets to the lungs. That message comes from the endothelial cells – special cells that line the blood vessels – along a "signalling pathway." http://medicalxpress.com/news/2012-10-life-lung-disease.html Medical research Wed, 24 Oct 2012 14:50:02 EST news270306129 New research indicates an increase in the number of US deaths and hospitalizations related to pulmonary hypertension.

However, the blood vessels in the lungs react differently: blood pressure in the lungs rises, often with deleterious effects on the lungs' tissue and the heart. Larissa A. Shimoda, PhD, Associate Professor of Medicine at the Johns Hopkins University School of Medicine in Baltimore, Md., has dedicated her research to learning why this happens and whether it's possible to treat the condition using drugs that are already on the market. http://medicalxpress.com/news/2011-04-dr-larissa-shimoda-discuss-mechanisms.html Other Mon, 11 Apr 2011 03:50:59 EST news221712633
