First author Dan Huh, a Wyss technology development fellow at the Institute, said: "We were inspired by how breathing works in the human lung through the creation of a vacuum that is created when our chest expands, which sucks air into the lung and causes the air sac
walls to stretch.
Microscopically, the air sacs
were thick, fibrotic, and edematous and had large areas of surface necrosis covered by extensive inflammatory detritus with the previously described fungal hyphae.
The lung transplant activates TNF production, causing cells that line the organ's vasculature and air sacs
to produce more reactive oxygen species and block sodium channels.
Case report 805: synovial sarcoma, epithelial hyperplasia in the humeral air sacs
, and formation of medullary bone.
Pneumonia Here, some of the tiny air sacs
, alveoli, in the lungs become inflamed and filled with pus (dead white blood cells) and fluid.
Nurses have a key role in treating lung disease, which is a progressive disease causing long-term suffering due to the blockage or narrowing of the small airways and damage to air sacs
in the lung.
According to researchers, the dinosaur has characteristics, like air sacs
, that link it to older dinosaur species found in South America.
Ponganis, his Scripps colleague Torrence Knower Stockard, and an international team found that when diving, penguins nearly deplete the oxygen in the special avian air sacs
attached to their lungs.
Inhaled meconium can inactivate the infants' own natural surfactant (the substance that keeps lung air sacs
open) and make breathing difficult.
Postmortem examination demonstrated multiple granulomas in the lungs and air sacs
Emphysema is an incurable condition where air sacs
in the lung are slowly destroyed, making it harder and harder to breathe.
Washington, Feb 18 (ANI): A new study has determined that balloon-like air sacs
in prehistoric dinosaurs helped reduced the density of their bodies, thus helping them take first flight.
Nurses have a key role in caring for patients suffering from COPD, which is a progressive disease causing long-term suffering due to blocking or narrowing of the small airways and damage to air sacs
in the lung.
Healthy lungs provide a flexible honey-comb of air sacs
where blood is recharged with oxygen.
Adult trematodes that infect the respiratory system release eggs into the air sacs
of the definitive avian host.
