in recent years, using sol-gel procedure for the purpose of laboratory and industrial synthesis of nano-structures, and especially silica nano-particles, has been significantly increased. in this research, silica particles were synthesized by sol-gel procedure and their physical and chemical properties were studied by means of scanning electron microscopy (sem), transmission electron microscopy...
The use of cysteinyl leukotriene receptor antagonists (LTRAs) for asthma therapy has been associated with a significant degree of interpatient variability in response to treatment. Some of that variability may be attributable to noncysteinyl leukotriene type 1 receptor (CysLT(1))-mediated inhibitory mechanisms that have been demonstrated for this group of drugs. We used a model of CysLT(1) sign...
Arylsulfatase B, purified to homogeneity from human eosinophils, is a tetrameric enzyme whose activity varied in accordance with the state of association of its monomeric subunits. The rate of dissociation of oligomeric forms was slow relative to the rate of the enzymatic reaction so that the kinetic properties of the enzyme depended on the concentration of the enzyme before assay. For concentr...
The seven-transmembrane G protein-coupled receptors activated by leukotrienes are divided into two subclasses based on their ligand specificity for either leukotriene B(4) or the cysteinyl leukotrienes (LTC(4), LTD(4), and LTE(4)). These receptors have been designated BLT and CysLT receptors, respectively, and a subdivision into BLT(1) and BLT(2) receptors and CysLT(1) and CysLT(2) receptors ha...
Leukotrienes are proinflammatory products of arachidonic acid oxidation by 5-lipoxygenase that have been shown to be involved in respiratory and cardiovascular diseases. The integral membrane protein FLAP is essential for leukotriene biosynthesis. We describe the x-ray crystal structures of human FLAP in complex with two leukotriene biosynthesis inhibitors at 4.0 and 4.2 angstrom resolution, re...
Given a role-explicit topic, we firstly determine its kernel-object, then we construct the corresponding modifier graph (Step-1). We perform graph clustering on the induced modifier graph using the algorithm by Noack [4]. Each modifier cluster is viewed as a representation of a particular subtopic. Corresponding to each modifier cluster, we generate the clusters of subtopic strings based on the...
