Published 1992Staff ViewISSN: 1089-7623Source: AIP Digital ArchiveTopics: PhysicsElectrical Engineering, Measurement and Control TechnologyNotes: A high-resolution fluorescence spectrometer using a Johann geometry in a backscattering arrangement was developed. The spectrometer, with a resolution of 0.3 eV at 6.5 keV, combined with an incident beam, with a resolution of 0.7 eV, form the basis of a high-resolution instrument for measuring x-ray absorption spectra. The advantages of the instrument are illustrated with the near-edge absorption spectrum of dysprosium nitrate.Type of Medium: Electronic ResourceURL: -

Published 1994Staff ViewISSN: 1077-3118Source: AIP Digital ArchiveTopics: PhysicsNotes: In this letter it is shown that high resolution Fe Kβ excitation spectra can be used to separately probe empty spin-up and spin-down final states. Spin-selective x-ray absorption spectra were obtained by selectively monitoring different regions of the Kβ emission. The fluorescence was excited with monochromatized synchrotron radiation and analyzed using a spherically bent Ge(620) crystal. Spin–polarization was demonstrated by showing that the 1s→3d transition at the Fe K edge is seen with Kβ1,3 detection, but missing in the excitation spectrum using Kβ' detection. The spin–polarization is also confirmed by ligand field atomic multiplet calculations that reproduce the Kβ spectra. Calculations are presented showing the applicability of spin–polarized Kβ detection to nearly all first transition metal ions. © 1994 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 2003Staff ViewISSN: 1365-3083Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: CD83 is a marker molecule for mature dendritic cells (DCs) but is also substantially expressed on activated T cells in humans and mice. Its function is unknown, but CD83 knockout mice show an impaired thymic maturation of CD4-positive cells and soluble CD83 inhibits partially antigen-specific responses in vitro pointing to a role of CD83 in the immune system. Here we show that CD83-positive T cells produce strongly increased amounts of interferon-γ and interleukin-2. In contrast, constitutive expression of CD83 on DCs alters neither the activation of DCs following addition of lipopolysaccharide nor the ability to present antigenic peptides. Thus, the expression of CD83 on T cells has direct functional consequences for tuning the activation threshold.Type of Medium: Electronic ResourceURL: -

ISSN: 1612-1112Keywords: Column liquid chromatography ; Ion-exchange chromatography ; Protein purification ; Pentosan polysulfate displacers ; Dextran sulfate displacersSource: Springer Online Journal Archives 1860-2000Topics: Chemistry and PharmacologyNotes: Summary Experimental studies were carried out to investigate the utility of pentosan polysulfate as a low molecular weight polyelectrolyte displacer for the purification of proteins in anion-exchange displacement systems. In addition, the influence of mobile phase salt concentration on displacer efficacy, protein-protein resolution, and displacement development were studied for several anionic displacers. It was found that while large polyelectrolytes (50 kd dextran sulfate) were efficient displacers for a wide range of salt concentrations, relatively small polyelectrolytes (3 kd pentosan polysulfate) were seen to act as an efficient displacer only under conditions of high salt micro-environments. In addition, for proteins exhibiting similar affinities, zone mixing at the protein-protein boundary was found to be quite sensitive to the salt concentration. Finally, displacement chromatography was successfully implemented for the separation of proteins from milk whey.Type of Medium: Electronic ResourceURL: -

A LALLS photometer and a UV detector, in series, were used to determine the molecular weight (MW) of the proteins, on-line. The results indicate that both, β-LACT A and B, were present as dimers in the buffer used for the mobile phase. The MWs of the proteins were about 6–8% higher than the theoretical MW of a dimer (∼37,000). Additional control studies have shown the presence of a high molecular weight species in both the proteins, which could possibly be an aggregate. This species was observed in the LALLS signal but was nearly absent in the UV signal. Our work has demonstrated the feasibility of interfacing LALLS with displacement chromatography for detecting impurities or aggregates which may be difficult to detect by conventional detectors used for chromatography.Type of Medium: Electronic ResourceURL: -

The formulation is based on the two-dimensional heat-conduction equation that includes the effects of moisture evaporation and pyrolysis of wood. The kinetic constants and adjustment factors needed in the model were estimated from the temperature profile test data of dimension lumber and other published sources. This technique offers a simple practical means to estimate the internal temperatures of structural lumber exposed to high temperatures, and has been effectively implemented in the analyses of protected wood assemblies exposed to fire situations.Additional Material: 10 Ill.Type of Medium: Electronic ResourceURL:
