This study evaluated the co-remediation performance of an active–passive process comprised passive permeable reactive barrier acid mine drainage (AMD) pre-treatment and active anaerobic digestion treatment AMD with effluent as a carbon source. The bioreactor was operated for 24 consecutive days peak chemical oxygen demand (COD) sulphate loading rates 6.6 kg COD/m3/day 0.89 SO42−/m3/day, respect...
The objective of the present study was to determine the impact of simulated apnea with intermittent hypoxia (IH) on endothelial barrier function and assess the underlying mechanism(s). Experiments were performed on human lung microvascular endothelial cells exposed to IH-consisting alternating cycles of 1.5% O2 for 30s followed by 20% O2 for 5 min. IH decreased transendothelial electrical resis...
The endothelial lining of the vessel wall is a permeable barrier, which is located at the interface between the vascular and the perivascular compartments. Although the endothelium acts as an efficient barrier that strictly separates the two compartments, it may also act as a permeable filter which allows selective exchange of solutes and water between the luminal and abluminal sides of the bar...
Ca(2+)-induced endocytotic vesicles undergo protein-mediated interactions to restore a selectively permeable barrier and propagated action potentials in severed invertebrate giant axons. Similar barrier-restoration phenomena observed in cultured mammalian cells with transected neurites suggest that cellular/molecular mechanisms that repair plasmalemmal damage are phylogenetically conserved.
