Human neutrophil elastase (NE) functions as a powerful serine protease capable of attacking a broad range of proteins. To examine the cellular site(s) of NE gene expression, a 0.65-kilobase cDNA (pPB15) complementary to the coding region of the NE gene was cloned from the cell line U937 using an oligonucleotide based on the known NE protein sequence. The sequence of pPB15 demonstrated that it c...

While the use of next-generation androgen receptor pathway inhibition (ARPI) therapy has significantly increased the survival of patients with metastatic prostate adenocarcinoma (AdPC), several groups have reported a treatment-resistant mechanism, whereby cancer cells can become androgen receptor (AR) indifferent and gain a neuroendocrine (NE)-like phenotype. This subtype of castration-resistan...

To study chronic catecholamine desensitization, mini-osmotic pumps were implanted subcutaneously to deliver NE, (0.5 micrograms/kg/min) or saline over 3-4 wk in dogs instrumented with left ventricular (LV) pressure gauges and arterial and left atrial pressure catheters. An acute challenge to NE (0.4 micrograms/kg/min) in intact, conscious dogs increased LV dP/dt by 1,531 +/- 208 mmHg/s before N...

Regional spillover of norepinephrine (NE), based on isotope dilution and single-compartment steady-state kinetics, is considered one of the best parameters for estimating organ sympathetic activity. However, the effects of local changes in clearance of NE on the spillover have not yet been investigated. We studied local NE kinetics and clearance in the forearm of 10 healthy subjects using intra...

We report all-electron and pseudopotential calculations of the ground-state energies of the neutral Ne atom and the Ne(+) ion using the variational and diffusion quantum Monte Carlo (DMC) methods. We investigate different levels of Slater-Jastrow trial wave function: (i) using Hartree-Fock orbitals, (ii) using orbitals optimized within a Monte Carlo procedure in the presence of a Jastrow factor...

Internal-mirror 543-nm He-20Ne and He-22Ne lasers are frequency-stabilized to the Lamb-dip of their tuning curves. Frequency stability of 2×10−11 and frequency resettability of 4×10−9 (or 2 MHz) are achieved. The absolute frequencies of the two lasers are determined by frequencycomparing with an iodine-stabilized 543-nm laser. The isotope shift between 20Ne and 22Ne is measured to one order of ...

Pharmacological studies in mammals suggest that norepinephrine (NE) plays an important role in promoting arousal. However, the role of endogenous NE is unclear, with contradicting reports concerning the sleep phenotypes of mice lacking NE due to mutation of dopamine β-hydroxylase (dbh). To investigate NE function in an alternative vertebrate model, we generated dbh mutant zebrafish. In contrast...

Neuroendoscopic (NE) surgery as a minimal invasive treatment for basal ganglia hemorrhage is a promising approach. The present study aims to evaluate the efficacy and safety of NE approach using an adjustable cannula to treat basal ganglia hemorrhage. In this study, we analysed the clinical and radiographic outcomes between NE group (21 cases) and craniotomy group (30 cases). The results indica...

Noscapine is a natural alkaloid with anti-angiogenesis activities. The aim of the present study was to examine the effect of noscapine on eutopic endometrium of endometriosis patients (EEE) and normal endometrium (NE)in a three-dimensional (3D) culture model. In this experimental in-vitro study, EEE (n = 8) and NE (n = 8) biopsies were taken from 16 reproductive aged women. The biopsie...

The nuclear envelope (NE) is a distinct subdomain of the ER, but few membrane components have been described that are specific to it. We performed a visual screen in tissue culture cells to identify proteins targeted to the NE. This approach does not require assumptions about the nature of the association with the NE or the physical separation of NE and ER. We confirmed that screening a library...
