The lungs of infants with respiratory distress syndrome are developmentally deficient in a material called surfactant, which helps prevent the collapse of the terminal air spaces (the future site of alveolar development) throughout the normal cycle of inhalation and exhalation. This deficiency of surfactant is related to inhibition from the ...
The major surfactant deficiency in premature infants relates to the lack of phosphatidylglycerol, even though it comprises less than 5% of pulmonary surfactant phospholipids. It is synthesized by head group exchange of a phosphatidylcholine enriched phospholipid using the enzyme phospholipase D .
This difference in inflation and deflation volumes at a given pressure is called hysteresis and is due to the air-water surface tension that occurs at the beginning of inflation. However, surfactant decreases the alveolar surface tension, as seen in cases of premature infants with infant respiratory distress syndrome. The normal surface tension ...
Multiple lung diseases, like ISD or RDS, in newborns and late-onsets cases have been linked to dysfunction of surfactant metabolism. Surfactant is a mixture of 90% phospholipids and 10% other proteins, produced by epithelial type II cells in the alveolar. This mixture is made and packaged into lysosomally- derived structures called lamellar bodies.
Meconium aspiration syndrome (MAS), also known as neonatal aspiration of meconium, is a medical condition affecting newborn infants. It describes the spectrum of disorders and pathophysiology of newborns born in meconium-stained amniotic fluid (MSAF) and have meconium within their lungs. Therefore, MAS has a wide range of severity depending on ...
A group of parents have accused the state of New Jersey of “secretly retaining” their newborn babies’ blood in a “creepy database” without their consent.. In a news release, the non ...
Surfactant therapy is the medical administration of pulmonary surfactant that is derived from outside of the body. Pulmonary surfactant is a soap-like chemical synthesized by type II alveolar pneumocytes and is of various lipids (80% phospholipids, 5-10% cholesterol, and ~10% surfactant-associated proteins). This biological fluid reduces ...
Those blankets are officially called "Kuddle-Ups." According to Jeremy Fogel, textiles division general manager at Medline, the company that manufactures the blankets, 1.5 million Kuddle-Ups are ...
