Nitazoxanide is active against Clostridium difficile strains with reduced susceptibility to metronidazole
(2011)Treatment strategies for Clostridium difficile infection (CDI) have changed little over the past two decades. Metronidazole and vancomycin continue to be the first-line antimicrobial treatments for CDI.1 While the drugs ... -
Nitrate Non-utilizing Mutants and Vegetative Compatibility Groups of Fusarium proliferatum and F. sacchari Isolated from Rice in the Peninsular Malaysia and Kalimantan, Indonesia.
(2009)A total of 26 isolates of Fusarium proliferatum and F. sacchari were isolated from rice in the Peninsular Malaysia and Kalimantan, Indonesia. Spontaneous chlorate-resistant sectors (CRSs) were recovered from all wild type ... -
Nitrates for the Management of Acute Heart Failure Syndromes, A Systematic Review
(2017-01-01)Intravenous nitrates are widely used in the management of acute heart failure syndrome (AHFS) yet with lack of robust evidence to support their use. We therefore sought to analyze all randomized studies that evaluated the ... -
Nitric oxide-dependent vasodilation is compromised in isolated pulmonary arteries from COX knockout mice
(2013-04)Cyclooxygenase (COX) has two isoforms and is essential for prostanoid synthesis. COX-1 is constitutive whilst COX-2 is induced in inflammation. Two COX products, prostacyclin (PGI2) and thromboxane (TxA2), regulate vessel ... -
Nitrogen and oxygen abundances in the Local Universe
(2016-06-01)We present chemical evolution models aimed at reproducing the observed (N/O) versus (O/H) abundance pattern of star-forming galaxies in the Local Universe. We derive gas-phase abundances from Sloan Digital Sky Survey (SDSS) ... -
Nitrogen-14 Nuclear Quadrupole Resonance Spectroscopy: : a powerful new analytical methodology for medicines authentication and counterfeit antimalarial analysis
(2013-02-05)We report the detection and analysis of a suspected counterfeit sample of the antimalarial medicine Metakelfin through developing Nitrogen-14 Nuclear Quadrupole Resonance (14N NQR) spectroscopy at a quantitative level. The ... -
NK1 antagonists based on seven membered lactam scaffolds
(2006-06-01)A new class of high affinity hNK(1)R antagonists based on seven-membered ring cores has been identified. This series, with relatively simple, compact structures, includes compounds with high affinity, good selectivity, and ... -
NLTE spectral analysis of helium-rich sdO stars from the southern HK survey.
(Astronomical Society of the Pacific, 1996)We have determined effective temperatures, surface gravities, and helium-to-hydrogen abundance ratios by fitting NLTE model atmospheres to high signal-to-noise- spectra of eight helium-rich sdO stars detected in the southern ... -
NLTE Spectral Analysis of Iron Group Elements in the Hot Subluminous O-star BD+28 4211
(Astronomical Society of the Pacific, 2003)An analysis of UV spectra of BD+28circ4211 obtained with the STIS spectrograph onboard the HST is presented. The spectral analysis is based on NLTE model calculation, which deal with the lineblanketing of iron group elements ... -
No category specificity in Alzheimer's disease: A normal aging effect
(2008)Examines category effects on tasks of picture naming, naming to definition, and word-picture matching in 38 patients with Alzheimer's disease (AD) and 30 elderly controls. Each task was matched across category on all ... -
