New research suggests that FPS-ZM1, an antagonist chemical compound that fights RAGE (the receptor for advanced glycation end-products), may treat COPD. In mice it was found this compound reverses the inflammatory response and has a protective role in COPD. “RAGE disturbances in pulmonary disorders are precise and effective strategies with beneficial clinical effects,” said Se-Ran Yang, D.V.M., Ph.D. Kangwon National University, Korea.

In their study, Yang and colleagues investigated the efficacy of RAGE-specific antagonist FPS-ZM1 administration in both in vivo and in vitro COPD models to determine the molecular mechanism by which RAGE influences ...

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 ...
