NASA technology benefits cardio-pulmonary patients

http://www.azosensors.com/news.aspx?newsID=5350 PUMA measures six components to evaluate metabolic function: oxygen and carbon dioxide partial pressure, volume flow rate, heart rate, and gas pressure and temperature. From those measurements, PUMA can compute the oxygen uptake, carbon dioxide output and minute ventilation (average expired gas flow rate). A small, embedded computer takes readings of each sensor and relays […]

Genetically modified virus produces heart’s own pacemaker in animals

http://technorati.com/technology/article/viruses-helped-to-make-the-natural/ Researchers at the Cedars-Sinai Heart Institute had another idea. They knew a gene called Tbx18 is normally activated during the sinoatrial node’s development, when an embryo is forming. So they set out to add Tbx18 into a functioning, fully grown heart. To do it, they inserted the code for this gene into a virus, […]
