The present experiment was designed to evaluate the emotional effects of positive and negative odorant stimuli. We examined the effects of continuous hydrogen sulphide (H2S) and vanillin stimulation on the magnitude of the acoustic startle reflex (measured at the M. orbicularis oculi) and on ratings of subjective valence in 16 healthy subjects. In accordance with the view that odors have emotional qualities, we found that H2S, a presumed negative foreground stimulus, significantly enhanced the startle-reflex amplitude relative to neutral air stimulation, whereas vanillin, a positive foreground stimulus, tended to reduce the reflex amplitude compared with neutral air stimulation. Both odorant stimuli were rated as equally intense by the subjects, and heart rate and electrodermal activity were not affected differentially by the two odorants.Type of Medium: Electronic ResourceURL: -

ISSN: 1089-7666Source: AIP Digital ArchiveTopics: PhysicsNotes: A stationary collisional-radiative model including both inelastic electron–atom and atom–atom collisions is used to examine nonequilibrium weakly ionized argon plasmas with atomic densities 1016–1020 cm−3, temperatures below 6000 K, and with different degrees of radiation trapping. It is shown that three-body atomic recombination (e+A++A→A+A) becomes important at high particle densities. Comparison is made between the present approach and Thomson's theory for atomic recombination.Type of Medium: Electronic ResourceURL: -

ISSN: 1089-7666Source: AIP Digital ArchiveTopics: PhysicsNotes: The general analytical solution of a collisional-radiative model, including atom–atom inelastic collisions, for nonequilibrium, partially ionized, steady-state plasmas is presented. This is applied to argon plasmas and the results are compared with previous numerical calculations. The model includes three atomic energy levels; the ground level, one excited level, and continuum, and assumes a Maxwellian electron and atom distribution functions. All rates for collisional and radiative processes are expressed as analytical functions. The model is solved algebraically to obtain analytical expressions for the electron and excited atom densities as a function of the plasma parameters. In the limit of an optically thick plasma the solution agrees with results for complete thermodynamic equilibrium. Solutions are presented for a wide range of conditions (3000≤Te≤24 000 K, 105≤Ne≤NA cm−3, 1014≤NA≤1018 cm−3).Type of Medium: Electronic ResourceURL: -

ISSN: 1089-7666Source: AIP Digital ArchiveTopics: PhysicsNotes: A three-level atomic model is used for determining the steady-state collisional-radiative coefficients in nonequilibrium partially ionized argon plasmas. Rate equations for populations of the atomic levels are coupled to an electron Boltzmann equation that includes inelastic processes. The solution of these coupled equations yields an analytical form for the non-Maxwellian electron distribution function. The reabsorption of radiation in the plasma is included through the use of Holstein radiation escape factors [Phys. Rev. 83, 1159 (1951)]. The cross sections in this model are included in the form of simple analytical expressions obtained from a numerical fitting of available experimental data. The results and limitations of the approach are discussed in a broad range of plasma conditions (electron temperature below 25 000 °K and atomic density of 1014–1018 cm−3).Type of Medium: Electronic ResourceURL: -

Published 1995Staff ViewISSN: 1460-9568Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Peripheral myelin protein PMP-22 is expressed by Schwann cells and is a constituent of peripheral nervous system (PNS) myelin. Two PMP-22 transcripts, SR73 and CD25, differing in their 5’non-coding sequences have been described. SR73 is present both in the PNS and in non-neural tissue, whereas CD25 mRNA is almost exclusively expressed in Schwann cells. PMP-22 mRNA is also present in the central nervous system (CNS), but at much lower levels than in the PNS. We have investigated the regional distribution of PMP-22 mRNA in the rat and mouse CNS by the reverse transcriptase-polymerase chain reaction method, using oligonucleotide primers specific for the SR73 or CD25 transcripts. SR73 mRNA was detected in all the CNS regions analysed, whereas the CD25 message was present only in the brainstem and the spinal cord. Localization of the PMP-22 transcripts, determined by in situ hybridization in 21 day-old animals, showed selective expression in the motor nuclei. The PMP-22 signal was very weak in the nuclei of the oculomotor and trochlear nerves and absent in the nucleus of the abducens nerve. A strong PMP-22 signal was observed in the motor nuclei of the trigeminal, facial, ambigus, vagus, hypoglossal and accessory spinal nerves and in the ventral horn of the spinal cord. The PMP-22-positive cells were identified as motoneurons on the basis of topographic and morphological criteria, as well as immunolabelling with neuron-specific antibodies. Immunostaining with specific anti-PMP-22 antibodies demonstrated that neurons expressing the PMP-22 message also expressed the corresponding protein in their cell bodies and axons. In contrast, neurons in the sensory nuclei of cranial nerves and dorsal root ganglion neurons were PMP-22-negative. In the trembler mouse, a PNS dysmyelinating mutant with a missense mutation in PMP-22, the motoneuronal expression of PMP-22 mRNA was either normal or increased.Type of Medium: Electronic ResourceURL: -
