Skin Cells Can Be Engineered Into Pulmonary Valves for Pediatric Patients

Researchers have found a way to take a pediatric patient’s skin cells, reprogram the skin cells to function as heart valvular cells, and then use the cells as part of a tissue-engineered pulmonary valve

Protein in ‘Good Cholesterol’ May Be a Key to Treating Pulmonary Hypertension

Lungandheartwith4F2.JPG

Oxidized lipids are known to play a key role in inflaming blood vessels and hardening arteries, which causes diseases like atherosclerosis. A new study at UCLA demonstrates that they may also contribute to pulmonary hypertension, a serious lung disease that narrows the small blood vessels in the lungs. Using a rodent model, the researchers showed that a peptide mimicking part of the main protein in high-density lipoprotein (HDL), the so-called “good” cholesterol, may help reduce the production of oxidized lipids in pulmonary hypertension. They also found that reducing the amount of oxidized lipids improved the rodents’ heart and lung function.

Over-Reliance of Pulse Oximetry for Children With Respiratory Infection

Among infants presenting to a pediatric emergency department with mild to moderate bronchiolitis, those with an artificially elevated oxygen saturation reading were less likely to be hospitalized or receive hospital care for more than 6 hours than those with unaltered readings, suggesting that these readings should not be the only factor in the decision to admit or discharge, according to a study in the August 20 issue of JAMA.

Researchers at RTI International, in collaboration with the University of North Carolina at Chapel Hill, have developed a new lung-on-chip microdevice for laboratory studies of respiratory challenges and therapeutics. The microdevice includes multiple vertically stacked cellular layers that mimic the structure of the airway tissue.
