In recent years, patients with emphysema have been increasing mainly among middle-aged and elderly males due to aging and excessive smoking. Emphysema makes brittle lungs, and in severe cases, holes develop in the lung tissue, causing air leakage. Researchers have developed a new sealant to close holes developed in lungs and blood vessels using Alaska pollock gelatin, and have reported that the sealant is about 12X stronger than conventional sealants and is able to resist pressure as high as ~2.8X the normal blood pressure.
The advantage is that it remains liquid at room temperature as it contains gelatin extracted from ...
