    μ-Opioid Receptors Mediate the Inhibitory Effect of Opioids on Dopamine-Sensitive Adenylate Cyclase in Primary Cultures of Rat Neostriatal Neurons (1990)

    Notizen: Abstract: The receptors mediating the inhibition of D1 dopamine receptor-stimulated adenylate cyclase by opioids were examined in primary cultures of rat neostriatal neurons. Adenylate cyclase activity was dose-dependently increased by the selective D1 dopamine receptor agonist SKF 38393 (EC50= 0.05 μM). This stimulation was fully antagonized by the selective D1 dopamine receptor antagonist SCH 23390 (1 μM). SKF 38393 (1 μM)-stimulated adenylate cyclase activity was strongly reduced (by almost 60%) by the highly selective μ-agonist [D-Ala2,MePhe4,Gly-ol5]-enkephalin (DAGO; EC50= 0.006μM) and high concentrations of the selective δ-agonist [d-Ser2(O-tert-butyl), Leu5]-enkephaIyl-Thr6 (DSTBU-LET; EC50= 0.13 μM) but not by the selective δ-agonist [d-penicillamine2, d-penicillamine5]enkephalin (DPDPE). D1 dopamine receptor-stimulated adenylate cyclase activity was also slightly reduced (by ∼20%) by high concentrations of the k-agonist U50,488 (EC50= 0.63 μM). The inhibitory effects of submaximally effective concentrations of DAGO, DSTBULET, and U50,488 were equally well antagonized by the μ-opioid receptor-selective antagonist naloxone (EC50 of ∼0.1 μM). Neither the irreversible δ-ligand fentanyl isothiocyanate (1 μM) nor the reversible δ-antagonist ICI 174864 (1 μM) reversed the inhibitory effects of DSTBULET. The inhibitory effects of DAGO and U50,488 were equally well reversed by high concentrations (〉0.1 μM) of the k-opioid receptor-selective antagonist norbinaltorphimine. The effect of DAGO (1 μM) was already detectable after 1 day in culture, whereas DPDPE (1 μM) had no effect even after 28 days in culture. These data indicate that an homogeneous population of μ-opioid receptors coupled as inhibitors to D1 dopamine receptor-stimulated adenylate cyclase is expressed in rat neostriatal neurons in primary culture.

    Single molecule lines and spectral hole burning of terrylene in different matrices (1994)

    Notizen: We observe fluorescence excitation lines of single terrylene molecules in three new polymer matrices (polyvinylbutyral, polymethylmethacrylate, and polystyrene) and in two crystals, n-hexadecane (polycrystalline Shpol'skii matrix) and anthracene single crystal. We also burn persistent spectral holes in bulk samples of these solutions for comparison to single molecule lines. In all matrices where hole burning is efficient enough, we find good agreement between the average width determined from the distribution of single molecules' linewidths and the homogeneous width deduced from spectral holes, which demonstrates the consistency and complementarity of the two techniques. © 1994 American Institute of Physics.

    Kinetics of optically detected magnetic resonance of single molecules (1994)

    Notizen: Various time-resolved experiments on optically detected magnetic resonance (ODMR) of single pentacene molecules in p-terphenyl at 1.8 K are described and discussed with the help of a model based on the optical-microwave Bloch equations. Intersystem crossing rates for this system are deduced from the ODMR spectra, from the fluorescence correlation function, which varies nonmonotonically with the microwave power, and from the analysis of the fluorescence recovery transients. We also discuss the enhancement of the ODMR effect on using fluorescence photons from single molecules as a time base to trigger the microwaves in fluorescence recovery experiments.

    TOWARD VERIFYING THE ASSUMPTIONS OF LABORATORY-INDUCED SLIPS OF THE TONGUE: THE OUTPUT-ERROR AND EDITING ISSUES (1981)

    Notizen: During the second half of the past decade, psycholinguistic models of speech production have been modified to include a “prearticulatory editing” component, the supposed function of which is to verify the linguistic integrity of impending phoneme strings destined for articulation. Empirical support for psycholinguistic editing comes primarily from studies by the present authors on laboratory-induced verbal slips. All of these studies have depended upon two crucial claims: that laboratory slips are errors of output, and that error-rate differentials are evidence of editing. Recently, however, it has been recognized that neither of these assumptions has been convincingly demonstrated, and consequently the editing models instigated by the earlier studies are being reassessed. The present study tested these two assumptions directly. The output-error assumption was supported by finding larger Galvanic Skin Resistance (GSR) responses for verbal slips than for correct vocalizations. The editing assumption was supported by finding that presumably edited vocal responses (identified by GSR) require more processing time (i.e., vocal response latency) than unedited responses. The reasoning from the empirical observations to conclusions about these assumptions is discussed in detail. Secondarily, a hypothesized social acceptability editing criterion was supported by the observation that neutral verbal slips outnumber taboo counterparts.

    COGNITIVE ENCODING PROCESSES: EVIDENCE FOR A GRAPHEMICALLY BASED SHORT-TERM MEMORY (1982)

    Notizen: Three competing models of word recognition processes currently receive psycholinguistic research support: direct encoding (i.e., word recognition proceeds from graphemes); indirect encoding (i.e., word recognition proceeds from a phonemic translation of graphemes); and dual access (i.e., word recognition can proceed from either graphemes or phonemes). Resolution of the conflict between these models has been hampered by methodological problems common to research techniques in this area. The two experiments reported in this study analyzes the competing models via the SLIP technique, which avoids those methodological problems. Support is yielded for the direct encoding model. Implications are discussed.

    Thermophysical properties of the lanthanide sesquisulfides. IV. Schottky contributions, magnetic, and electronic properties of ε-phase Yb2S3 and Lu2S3 (1993)

    Notizen: The heat capacities of ε-phase Yb2S3 and Lu2S3 have been determined from 6 to 350 K and their thermodynamic properties evaluated. The resolution of the Schottky and magnetic properties by evaluation of the lattice heat capacity is shown to be in accord with spectroscopically determined energy levels. The lattice heat capacity of Yb2S3 was determined by means of the Komada–Westrum phonon distribution model. Excess heat-capacity contributions were thus evaluated and analyzed as Schottky and magnetic heat capacities. A phase transition associated with magnetic ordering was detected in the heat capacity of Yb2S3 near 7 K with an entropy content of 0.68R. The entropies at 298.15 K are 22.77R and 19.74R for Yb2S3 and for Lu2S3.

    Photon bunching in the fluorescence from single molecules: A probe for intersystem crossing (1993)

    The Journal of Chemical Physics 98 (1993), S. 850-859

    Thema: Physik , Chemie und Pharmazie
    Notizen: Fluorescence photons emitted by a single molecule trapped in a solid at low temperature are correlated in time. A simple theory of the correlation pattern is presented, including in the same formalism photon antibunching from coherent Rabi oscillations and photon bunching due to incoherent quantum transitions between electronic levels. The correlation method is applied to single pentacene molecules in a para-terphenyl crystal. A clear photon bunching allows us to determine the ISC rates for each molecule. We attribute the scatter of our results for the transition rate between excited singlet and triplet states, and the difference with the average value taken from the literature, to molecular distortions induced by crystal defects in our small sample. We conclude that the correlation method associated to single molecule spectroscopy has a great potential to study dynamical processes on intermediate time scales in condensed matter.

    The evolution of strongly modulated, low-frequency, moderate-amplitude wave packets in a dispersive plasma (1993)
    New York, NY : American Institute of Physics (AIP)
    Physics of Fluids 5 (1993), S. 42-54

    Thema: Physik
    Notizen: The evolution of strongly modulated wave packets in a dispersive plasma that propagate parallel to the magnetic field is studied. Modulation effects are shown to reduce significantly (≈30%) the rate of spreading from that due to dispersion alone. For fluidlike behavior, nonlinearity has its greatest impact on evolution when the linear sound speed and initial wave packet speeds are well matched, resulting in a strong coupling between the wave magnetic and sonic components. Ion kinetic processes reduce the impact of nonlinearity and cause the rate of spreading to approach that expected from dispersion alone as the ratio of ion and electron temperatures, Ti/Te→4. For β(approximately-greater-than)1 and Ti/Te∼1, the coupled waveforms correspond qualitatively to kinetic treatments of the derivative nonlinear Schrödinger (DNLS) equation.
