Contextual fear conditioning under training conditions involving high stressor intensities has been proposed as an animal model for traumatic memories. The strength of memory for this task has been related to the intensity of the conditioning stressor and ...
G protein-coupled receptors (GPCRs) constitute a large class of seven transmembrane proteins, which bind selectively agonists or antagonists with important consequences for cellular signaling and function. Comprehension of the mol. details of ligand bindin ...
The Drosophila immune system discriminates between different classes of infectious microbes and responds with pathogen-specific defense reactions through selective activation of the Toll and the immune deficiency (Imd) signaling pathways. The Toll pathway ...
A method is presented to form gold-electrode-tethered lipid bilayers with exceptionally high elec. resistances. Elec. impedance spectroscopy is used to monitor the bilayer incorporation of a ligand-gated ion channel protein and the modulation of its channe ...
The reductive cleavage of Me vinyl-b-ionyl ether or the deprotonation of 3,2',6',6'-tetramethyl-5-(1-cyclohexenyl)-1,3-pentadiene gives rise to an organometallic C15 species that combines selectively with a variety of electrophiles at the terminal chain po ...
Disaccharide and oligosaccharide mimics are potentially more selective glycosidases inhibitors than simple monosaccharide mimics. They represent also more selective ligands for lectins and oligosaccharide receptors and can become immunostimulating agents. ...
Lipophilic polymer membranes incorporating binding sites are widely used in various potentiometric, amperometric, and optical sensors. Here, we report on the biofunctional modification of the surface of a Ca2+-selective membrane. A photoactivatable biotin ...
Existing evidence indicates that 21-days exposure of rats to restraint stress induces dendritic atrophy in pyramidal cells of the hippocampus. This phenomenon has been related to altered performance in hippocampal-dependent learning tasks. Prior studies ha ...
A review. Cell-based assays are the predominant means of assessing activation of ionotropic receptors and G protein-coupled receptors (GPCRs), but are limited by their inherent complexity. Here we present an approach to immobilize receptors stably and with ...
Gas phase methylation of catechol by methanol over modified gamma-alumina catalysts is studied experimentally. The catalyst composition and the reaction conditions are optimized to attain the highest selectivity towards 3-methylcatechol (C-methylation) or ...
