The histaminergic system has been speculated to be involved in the inhibitory control of drug reward, H-1 and H-2 antagonists having been found to potentiate conditioned place preference induced by morphine or cocaine. In contrast, the role of H-3 receptors in cocaine-induced place preference is still unknown. The present study tested the effects of thioperamide (0, 10 and 20 mg/kg, i.p.), an H-3 autoreceptor antagonist, on the development of a conditioned place preference induced by cocaine (0, 2 and 8 mg/kg, i.p.) in C57BL/6J mice. Thioperamide was injected 10 min before each cocaine-pairing session. The activity scores recorded on the first cocaine-pairing session were also used to test the effects of thioperamide on cocaine-induced locomotor activity. Thioperamide alone had no reinforcing effects and did not affect the conditioned place preference induced by 8 mg/kg cocaine. However, thioperamide dose-dependently revealed a conditioned place preference induced by 2 mg/kg cocaine, a dose that was inactive per se. Finally, thioperamide dose-dependently potentiated the stimulant effects of cocaine, in spite of its slight hypolocomotor effect when given alone. Our results strongly suggest that H3 antagonists potentiate the stimulant and reinforcing effects of cocaine in mice. © 2004 Elsevier B.V. All rights reserved. [less ▲]

Thin conductive magnetic shells are accounted for by means of two different time-domain magnetodynamic finite-element formulations, namely the magnetic field formulation and the magnetic vector potential formulation. Both approaches are an extension of the classical linear frequency-domain thin-shell approximation. The interface conditions for the magnetic field formulation and the vector potential formulation are expressed in terms of the average current density and the average flux density, respectively, together with a number of higher-order components of these quantities. The proposed time-domain thin-shell approaches are validated by means of a 3D magnetodynamic problem. The results are shown to agree well with those obtained with a fine model, whereas the computation time is significantly reduced. [less ▲]

Purpose - The aim of the present paper is to compare the performances of a finite-element perturbation technique applied either to the h- conform magnetodynamic formulation or to its b-conform counterpart in the frame of nondestructive eddy-current testing problems. Design/methodology/approach - In both complementary perturbation techniques, the computation is split into a computation without defect (unperturbed problem) and a computation of the field distorsion due to its presence (perturbation problem). The unperturbed problem is conventionally solved in the complete domain. The source of the perturbation problem is then determined by the projection of the unperturbed solution in a relatively small region surrounding the defect. The discretisation of this reduced domain is chosen independently of the dimensions of the excitation probe and the specimen under study and is thus well adapted to the size of the defect. Findings - The accuracy of the perturbation model is evidenced by comparing the results of the two counterpart formulations to those achieved in the conventional way for different dimensions of the reduced domain. The size of the reduced domain increases with the size of the defect at hand. This proposed sub-domain approach eases considerably the meshing process and speeds-up the computation for different probe positions. Originality/value - At a discrete level, the impedance change due to the defect is efficiently and accurately computed by integrating only over the defect itself and a layer of elements in the reduced domain that touches its boundary. Therefore, no integration of any flux variation in the coils is required. [less ▲]

We present the first ground-based detection of thermal emission from an exoplanet in the H-band. Using HAWK-I on the VLT, we observed an occultation of WASP-19b by its G8V-type host star. WASP-19b is a Jupiter-mass planet with an orbital period of only 19 h, and thus, being highly irradiated, is expected to be hot. We measure an H-band occultation depth of 0.259[SUP]+0.046[/SUP][SUB]-0.044[/SUB]%, which corresponds to an H-band brightness temperature of T[SUB]H[/SUB] = 2580 ± 125 K. A cloud-free model of the planet's atmosphere, with no redistribution of energy from day-side to night-side, under predicts the planet/star flux density ratio by a factor of two. As the stellar parameters, and thus the level of planetary irradiation, are well-constrained by measurement, it is likely that our model of the planet's atmosphere is too simple.

First published in the "Kant-Studien" (1909), Rickert's "two ways of the theory of knowledge" is a master-piece of the debate between neo-Kantianism and Husserl's phenomenology. In this text, Rickert - with Windelband and Lask one of the main representatives of the Heidelberg neo-Kantian school - presents in a clear and synthetic way the principles of his critical philosophy. The French translation of the German Text is here accompanied by a substantive commentary (100 p.) on the Rickert-Husserl relationship. Discussed topics include: antipsychologism and normative logic, theory of obviousness, nature of judgement and truth, heterological relation between subject and object, etc. Those topics are examined from the methodological distinction between "noetical analysis" (or act-analysis) and "noematical analysis" (content-analysis), which can be regarded at some extend as common to Husserl and Rickert.

BACKGROUND: Safety data are lacking on influenza vaccination in general and on A (H1N1)v vaccination in particular in patients with inflammatory bowel disease (IBD) receiving immmunomodulators and/or biological therapy. AIMS AND METHODS: The authors conducted a multicentre observational cohort study to evaluate symptoms associated with influenza H1N1 adjuvanted (Pandemrix, Focetria, FluvalP) and non-adjuvanted (Celvapan) vaccines and to assess the risk of flare of IBD after vaccination. Patients with stable IBD treated with immunomodulators and/or biological therapy were recruited from November 2009 until March 2010 in 12 European countries. Harvey-Bradshaw Index and Partial Mayo Score were used to assess disease activity before and 4 weeks after vaccination in Crohn's disease (CD) and ulcerative colitis (UC). Vaccination-related events up to 7 days after vaccination were recorded. RESULTS: Of 575 patients enrolled (407 CD, 159 UC and nine indeterminate colitis; 53.9% female; mean age 40.3 years, SD 13.9), local and systemic symptoms were reported by 34.6% and 15.5% of patients, respectively. The most common local and systemic reactions were pain in 32.8% and fatigue in 6.1% of subjects. Local symptoms were more common with adjuvanted (39.3%) than non-adjuvanted (3.9%) vaccines (p < 0.0001), whereas rates of systemic symptoms were similar with both types (15.0% vs 18.4%, p = 0.44). Among the adjuvanted group, Pandemrix more often induced local reactions than FluvalP and Focetria (51.2% vs 27.6% and 15.4%, p < 0.0001). Solicited adverse events were not associated with any patient characteristics, specific immunomodulatory treatment, or biological therapy. Four weeks after vaccination, absence of flare was observed in 377 patients with CD (96.7%) and 151 with UC (95.6%). CONCLUSION: Influenza A (H1N1)v vaccines are well tolerated in patients with IBD. Non-adjuvanted vaccines are associated with fewer local reactions. The risk of IBD flare is probably not increased after H1N1 vaccination. [less ▲]

Since 1949, solar absorption spectra have been acquired at the Jungfraujoch observatory (Swiss Alps, 46.5°N, 8.0°E, 3580 m a.s.l.), first with grating spectrometers, then with Fourier transform infrared (FTIR) spectrometers. Most observations collected with these instruments encompass water vapor absorptions, even the narrow spectral domains regularly recorded with the grating instruments to monitor the evolution of important atmospheric constituents. The aim of this work is to analyze all available spectra containing usable H2O absorption lines, to derive a long-term record of its total column in the atmosphere above the Jungfraujoch. In addition, more recent FTIR broadband spectra, with better signal-to-noise ratio and resolution, will be analyzed with state of the art algorithm, in order to derive information on the vertical distribution of H2O.

We have studied the effects of the H3-receptor agonist (R) alpha-methylhistamine [(R) alpha-MeHA] and the H3-receptor antagonist thioperamide (Thiop) on basal- and carbachol-stimulated vascular gastrin release (GR) and somatostatin release (SR) by the isolated rat stomach. Carbachol dose-dependently stimulated and inhibited GR and SR, respectively. Maximal stimulation of GR (500 +/- 112 percent of basal; p < .01), and maximal inhibition of SR (-62 +/- 9 percent under basal; p < .01) were obtained with 1 micron carbachol. Neither (R)alpha-MeHA nor Thiop, up to 10 microns, affected GR. However, SR was dose-dependently enhanced by Thiop (25 +/- 8 percent for 10 microns). Carbachol stimulation of GR was strongly inhibited by Thiop (30 +/- 7 percent for 100 nM and 73 +/- 14 percent for 1 microgram), whereas it was potentiated by (R)alpha-MeHA. Carbachol inhibition of SR was reversed by Thiop and (R)alpha-MeHA. However, the reversal effect of (R)alpha-MeHA was prevented by the CCKB/gastrin receptor antagonist PD134308. These results support H3-receptor regulation of basal and cholinergically-stimulated GR and SR. [less ▲]

High-resolution spectra of the Jovian aurora have been obtained with unprecedented spectral resolution in the 900-1190 Ì· window with the the Far Ultraviolet Spectroscopic Explorer (FUSE), using the 30"x30" LWRS aperture. All observed features belong to the H[SUB]2[/SUB] transitions from the B, C, B', D, B" and D' electronic states to the ground-state. These emissions are excited by inelastic collisions of the primary and secondary auroral electrons with H[SUB]2[/SUB] molecules. The relative intensity distribution of the observed lines depends on the rotational temperature of the emitting layer and self-absorption. Below 1100 Ì· , the transitions leading to the v" = 0, 1 and 2 levels of ground-state are partially or totally absorbed by H[SUB]2[/SUB], giving indications about the vibrational H[SUB]2[/SUB] distribution and overlying column. After a validation with an unabsorbed and a self-absorbed laboratory spectrum obtained in controlled conditions (100K, 300 eV), this study compares the observations and synthetic spectra, generated by a code including the B, C and B', D, B" and D' Rydberg states. The rotational and vibrational H[SUB]2[/SUB] temperatures are determined as well as the overlying H[SUB]2[/SUB] column. The combination of these parameters is used to determine the depth of the auroral energy deposition. This work is based on data obtained for the Guaranteed Time Team by the NASA-CNES-CSA FUSE mission operated by the Johns Hopkins University. French participants are supported by CNES. Financial support to U.S. participants has been provided by NASA contract NAS5-32985. [less ▲]

This work is caractherized by the following phases: alcoholistic symptom control, individual and family story narration and renegociation and reshaping of couple spaces/times. Symptom gradual dissolution has permitted the relaunching of individual, couple and familial planning as a fundamental dimension for improving general quality life of elderly couple. [less ▲]

Objectives: This study aimed to create a new French version of the Hay and Jacoby habit-training procedure (1996; 1999) and apply it to novel populations to determine the degree to which habit and recollection were affected. Method: 36 young, 32 middle-aged, and 37 older adults participated in Experiment 1. 17 controls, 17 patients with amnestic Mild Cognitive Impairment (a-MCI), and 17 patients with Alzheimer's disease (AD) were involved in Experiment 2. Participants were assessed across a variety of demographic, neuropsychological and psychopathological variables (e.g., depressive affects, subjective experience of cognitive failures, interference sensitivity). The habit-training process-dissociation was used to explore the cognitive mechanisms underlying memory slips to separate the contribution of habit and recollection to memory performance. Results: The data show a very clear pattern of decreased recollection with age, F(2, 102) = 25.12, p < .001, η p2 = .197, and age-related neurological impairment, F(2, 48) = 39.22, p < .001, η p2 = .62, with intact use of habit-based memory. Additional evidence for the validity of the process estimates is provided by theoretically meaningful correlations between the process estimates and measures of attentional control (Stroop test: r = −0.40) and subjective memory complaint ( r = −0.45). Conclusions: Although likely not the same as familiarity, the data add to a growing literature suggesting that controlled forms of memory decline with age and in age-related neurological conditions (MCI and AD) whereas more automatic forms of memory (habit) remain intact. This research should improve understanding of memory complaints, preclinical and clinical dementia, and help target processes for rehabilitation.
