TL;DR: The results suggest that cellular redox status is a determinant of pulmonary arterial endothelial cell TPMET activity, with T PMET activity more highly correlated with the poise of the NADH/NAD(+) redox pair.
Abstract: Pulmonary arterial endothelial cells possess transplasma membrane electron transport (TPMET) systems that transfer intracellular reducing equivalents to extracellular electron acceptors. As one asp...

Abstract: Absorption spectra of lanthanideions in perfluorinated (PF) plastic solution were measured, and the radiative properties were determined by the absorption measurements and the Judd- Ofelt theory. Fluorescence spectrum of Nd3+ in PF plastic solution from 900 nm to 1350 nm, pumped at 580 nm, were measured for the first time. Lasing properties of a rhodamine 6G-doped graded-index plastic optical fiber laser (GI-POFL) and a rod laser were investigated. All measurements demonstrated the superior performance of the GI-POFL. This paper also discusses the lasing properties on the basis of near-field pattern measurements.© (2002) COPYRIGHT SPIE--The International Society for Optical Engineering.
