Does phospholipid Composition in Synthetic Surfactants be Important for Tidal Volumes and Alveolar Stability in Surfactant-Treated Preterm Newborn Rabbits?
Phospholipid composition is important for VT while the SP-B and SP-C analogues increase alveolar stability at end-expiration. Synthetic surfactant consisting of unsaturated and saturated phosphatidylcholines, POPG and the analogues of SP-B and SP-C has similar activity as Curosurf regarding VT and LGV in an animal model using preterm newborn rabbits ventilated without positive end-expiratory pressure.
This study provides evidence that SLC2A9 splice variants act as high-capacity urate transporters and is one of the first functional characterisations of findings from genome-wide association scans. We did not find an association of the SLC2A9 gene with blood pressure in this study. Our findings suggest potential pathogenic mechanisms that could offer a new drug target for gout.
