Calculation of absolute ionisation cross sections of He, He*, He+, Ne, Ne*, Ne+, Ar, Ar*, Hg and Hg*
Neuroendocrine (NE) cells represent a minor cell population in the epithelial compartment of normal prostate glands and may play a role in regulating the growth and differentiation of normal prostate epithelia. In prostate tumor lesions, the population of NE-like cells, i.e., cells exhibiting NE phenotypes and expressing NE markers, is increased that correlates with tumor progression, poor prog...
BACKGROUND During the pathological destruction of lung tissue, neutrophil elastase (NE) degrades elastin, one of the major constituents of lung parenchyma. However there are no non-invasive methods to quantify NE degradation of elastin. We selected specific elastin fragments generated by NE for antibody generation and developed an ELISA assay (EL-NE) for the quantification of NE-degraded elasti...
The relevance of local removal and release of norepinephrine (NE) for antecubital venous plasma NE concentration was studied in 22 healthy subjects. Arterial and venous plasma NE and forearm blood flow were measured during intra-arterial infusion of two doses of NE, intra-arterial NE infusion with two doses of sodium nitroprusside, intravenous infusion of NE with intra-arterial infusion of four...
Spillover of norepinephrine (NE) into plasma is used frequently as an index of NE release and therefore of sympathetic nerve activity. An important limitation of NE spillover is that it reflects not only release but also uptake processes that intervene before the transmitter reaches the circulation. To overcome this limitation, we developed a method for estimating NE release based on measuremen...
OBJECTIVE Endothelin-1 (ET-1) potentiates norepinephrine (NE)-induced contractile responses. An impairment of cardiac NE re-uptake by the neuronal NE transporter (NET) contributes to an increased NE net release in failing hearts. We hypothesized that both phenomena are caused by ET-1-mediated inhibition of NET. METHODS [3H]-NE-uptake, electrical field stimulation-evoked NE overflow and left v...
