Biodegradability of inhaled p-aramid respirable fibre-shaped particulates: representative of other synthetic organic fibre-types?
Our data indicate that components of lung fluids coat and catalyze the p-aramid, thereby predisposing the RFP to enzymatic cleavage. This could play a significant mechanistic role in facilitating the transverse cleavage or shortening of inhaled p-aramid RFP in the lungs of exposed rats and hamsters.
Overall, these data indicate that early infections in LT patients are characterized by significant mortality. In particular, an early infection caused by CRKP has an adverse impact on survival in these patients suggesting an urgent need for adopting preventive measures to avoiding this complication.
