OBJECTIVES: To establish the level of observer variation for the current ATS/ERS/JRS/ALAT criteria for a diagnosis of usual interstitial pneumonia (UIP) on CT among a large group of thoracic radiologists of varying levels of experience. MATERIALS AND METHODS: 112 observers (96 of whom were thoracic radiologists) categorised CTs of 150 consecutive patients with fibrotic lung disease using the ATS/ERS/JRS/ALAT CT criteria for a UIP pattern (3 categories--UIP, possibly UIP and inconsistent with UIP). The presence of honeycombing, traction bronchiectasis and emphysema was also scored using a 3-point scale (definitely present, possibly present, absent). Observer agreement for the UIP categorisation and for the 3 CT patterns in the entAUe observer group and in subgroups stratified by observer experience, were evaluated. RESULTS: Interobserver agreement across the diagnosis category scores among the 112 observers was moderate, ranging from 0.48 (IQR 0.18) for general radiologists to 0.52 (IQR 0.20) for thoracic radiologists of 10-20 years' experience. A binary score for UIP versus possible or inconsistent with UIP was examined. Observer agreement for this binary score was only moderate. No significant differences in agreement levels were identified when the CTs were stratified according to multidisciplinary team (MDT) diagnosis or patient age or when observers were categorised according to experience. Observer agreement for each of honeycombing, traction bronchiectasis and emphysema were 0.59+/-0.12, 0.42+/-0.15 and 0.43+/-0.18, respectively. CONCLUSIONS: Interobserver agreement for the current ATS/ERS/JRS/ALAT CT criteria for UIP is only moderate among thoracic radiologists, AUrespective of theAU experience, and did not vary with patient age or the MDT diagnosis.

In 1982, we developed a new coma scale, the Glasgow-Liege scale, which combines the quantified analysis of five brain stem reflexes with the Glasgow methodology. The present study was undertaken to determine to what extent agreement exists among different raters assessing brain stem reflexes (Parameter R) and to compare the results with those observed from motor responses (Parameter M). We show the good agreement achieved by different examiners in the evaluation of brain stem reflexes. Brain stem reflexes offer a slightly higher agreement (kappa = 0.69) than that of the study of motor response (kappa = 0.65). Within Parameters M and R, we observed less agreement in the evaluation of flexion responses and in the interpretation of oculocephalic reactions. The reliability of the evaluation of M and R parameters justifies the use of the Glasgow-Liege scale as a means for evaluating disturbances of consciousness. [less ▲]

Cet article propose d’explorer la manière dont Judith Butler remobilise la thèse althussérienne de l’interpellation dans La Vie psychique du pouvoir . Nous essaierons de saisir les éléments qui nous paraissent enrichir la problématique althussérienne, suggérant que la compréhension de la dimension psychique du pouvoir qui ressort de sa lecture permet de complexifier la relation du sujet au pouvoir. Afin de tisser des liens précis entre l’interpellation chez Althusser et la subjectivation chez Butler, nous examinerons d’abord le rôle que Nietzsche et Foucault recouvrent dans la formulation de la théorie de la subjectivation chez Butler. Ensuite, il s’agit de comprendre en quoi la matérialité et l’ambiguïté des mécanismes de subjectivation, qui déjà caractérisent l’interpellation althussérienne, deviennent chez Butler les sources d’une relation critique aux conditions d’émergence du sujet. Enfin nous préciserons comment elle mobilise de telles sources pour élaborer cette figure de la psychanalyse qu’est la mélancolie et pour décrire sa transformation en deuil. [less ▲]

Two new magnetic cluster-based 3D coordination polymers consisting of μ3-oxo-centered cationic homometallic [FeIII 3O(O2CCMe3)6]+ or neutral heterometallic [FeIII 2CoIIO(O 2CCMe3)6] coordination clusters bridged by different N,N′-donor ligands into three-dimensional networks of {[Fe 3O(O2CCMe3)6(4,4′-bpy) 1.5](OH)·0.75(CH2Cl2)·x(H 2O)}n (1, x ≤ 8) and {[Fe2CoO(O 2CCMe3)6(bpe)0.5(pyz)]}n (2) (where 4,4′-bpy = 4,4′-bipyridine; bpe = 1,2′-bis(4- pyridyl)ethylene; pyz = pyrazine) have been prepared under solvothermal conditions. Single-crystal X-ray diffraction studies reveal the existence of a 6-fold interpenetrated network with rare (8,3)-c (etc) topology for 1 and a 3-fold interpenetrated network with (10,3)-b (ths) topology for 2. The interpenetration effectively results in very low BET surface areas, and the compounds have to be regarded as nonporous. Magnetic studies of 1 and 2 point to both ferro- and antiferromagnetic intra- and intercluster exchange interactions between the isotropic FeIII and the strongly anisotropic Co II spin centers. 57Fe Mössbauer spectroscopy confirms the uniform ferric (+III) valence state in both 1 and 2, and low-temperature data for 1 point toward distinct hyperfine fields for the Fe sites. © 2014 American Chemical Society.

Data from the Far Ultraviolet Imager (FUV) on the Imager for Magnetopause-to-Aurora Global Exploration (IMAGE) satellite show that subauroral proton arcs appear in the afternoon sector during geomagnetically disturbed periods when the interplanetary magnetic field rotates either from south to north or from west to east and when the magnetosphere is moderately compressed. Time series of proton aurora images show that the proton emissions are generally aligned along the equatorward part of the auroral oval. However, when interplanetary magnetic field (IMF) B[SUB]z[/SUB] changes from negative to positive the auroral oval contracts toward higher latitudes while the ring current proton precipitation remains stationary, resulting in a separation of several degrees between the latitude of the new oval position and a subauroral proton arc in the afternoon sector. A similar effect occurs when IMF B[SUB]y[/SUB] rotates from negative to positive, in which case the oval in the afternoon sector retreats toward higher latitudes, again leaving a separation between the oval and the subauroral proton arc of several degrees. Comparisons with low-altitude and geosynchronous satellite data show that the subauroral proton arc is caused by the precipitation of protons with energies from several keV to 30 keV and is likely associated with the existence of a plasmaspheric ``drainage plume.'' In contrast, the proton emissions along the main oval are caused by protons with energies generally less than 10 keV. [less ▲]

Dopaminergic and adrenergic receptors are G-protein-coupled receptors considered to be different based on their pharmacology and signaling pathways. Some receptor subtypes that are members of one family are actually closer in phylogenetic terms to some subtypes belonging to the other family, suggesting that the pharmacological specificity among these receptors from different families is not perfect. Indeed, evidence is accumulating that one amine can cross-talk with receptors belonging to the other system. However, most of these observations were collected in vitro using artificial cell models transfected with cloned receptors, so that the occurrence of this phenomenon in vivo as well as its distribution in the central nervous system is not known. In this study the pharmacological basis of possible in vivo interactions between dopamine and alpha(2)-adrenergic receptors was investigated in quail, zebra finches, and rats. Binding competitions showed that dopamine displaces the binding of the selective alpha(2)-adrenergic ligand, [(3)H]RX821002, in the brain of the three species with an affinity approximately 10-28-fold lower than that of norepinephrine. Dopamine also displaces with an affinity 3-fold lower than norepinephrine the binding of [(3)H]RX821002 to human alpha(h2A)-adrenergic receptors expressed in Sf9 cells. The anatomical distribution of this interaction was assessed in brain slices of quail and rat based on autoradiographic methods. Both norepinephrine and dopamine significantly displace [(3)H]RX821002 binding in all brain nuclei considered. Together, these data provide evidence for an interaction between the dopaminergic and noradrenergic systems in the vertebrate brain, albeit with species variations. [less ▲]

The use of random metallic nanowire networks as transparent conductive materials (TCMs) is increasing rapidly. These materials can be used in flexible/stretchable electronics, flexible displays, touch screens, photovoltaics or as transparent heaters. Metallic nanowire networks can be deposited by using low-cost and scalable deposition techniques and exhibit very interesting electrical, optical, thermal and mechanical properties. In addition to usual material defects (such as grain-boundaries) any deviation from a “perfect” infinite network (i.e. nanowire length distributions, finite device size or nanowire curvature for instance) play a prominent role in the physical properties of the resulting percolating network. Using Monte Carlo simulations, and based on experimental available wires the effects of these defects are explored. Experimental work is focused on the influence of nanowire density as well as defects within the nanostructured network such as the inhomogeneity of the network, the grain-boundary along a nanowire, the morphological nanowire instabilities… The influence of these defects on the physical properties of this promising nanostructured network will be presented [less ▲]

E-cadherin expression is repressed by ZEB2/SIP1 while it is induced by KLF4. Independent data from the literature indicate that these two transcription factors could bind close to each other in the proximal region of the E-cadherin gene promoter. We have here explored a potential competition between ZEB2 and KLF4 for the binding to the E-cadherin promoter. We show an inverse correlation between ZEB2 expression levels and KLF4 recruitment on the E-cadherin promoter in three breast cancer cell lines and in A431/HA.ZEB2 cells in which ZEB2 expression is induced by doxycycline (DOX). We identified a region of the E-cadherin promoter bound by KLF4 which is necessary for the activation of the E-cadherin promoter activity after KLF4 overexpression. This region is localized between positions -28 and -10 and thus overlaps with one of the ZEB2 binding sites. Deleting the bipartite ZEB2 binding site results in increased KLF4 induced E-cadherin promoter activity. Taken together, our results suggest that E-cadherin expression in cancer cells is controlled by a balance between ZEB2 and KLF4 expression levels. [less ▲]

In photosynthetic eukaryotes, the redox state of the plastoquinone (PQ) pool is an important sensor for mechanisms that regulate the photosynthetic electron transport. In higher plants, a multimeric nicotinamide adenine dinucleotide (phosphate) (NAD(P))H dehydroge- nase (NDH) complex and a plastid terminal oxidase (PTOX) are involved in PQ redox homeostasis in the dark. We recently demonstrated that in the microalgae Chla- mydomonas reinhardtii, which lacks the multimeric NDH complex of higher plants, non-photochemical PQ reduction is mediated by a monomeric type-II NDH (Nda2). In this study, we further explore the nature and the importance of non-photochemical PQ reduction and oxidation in relation to redox homeostasis in this alga by recording the ‘dark’ chlorophyll fluorescence transients of pre-illuminated algal samples. From the observation that this fluorescence tran- sient is modified by addition of propyl gallate, a known inhibitor of PTOX, and in a Nda2-deficient strain we conclude that it reflects post-illumination changes in the redox state of PQ resulting from simultaneous PTOX and Nda2 activity. We show that the post-illumination fluo- rescence transient can be used to monitor changes in the relative rates of the non-photochemical PQ reduction and reoxidation in response to different physiological situa- tions. We study this fluorescence transient in algae acclimated to high light and in a mutant deficient in mitochondrial respiration. Some of our observations indi- cate that the chlororespiratory pathway participates in redox homeostasis in C. reinhardtii. [less ▲]

We discuss the current induced magnetization dynamics of spin valves F-0 vertical bar N vertical bar SyF where the free layer is a synthetic ferrimagnet SyF made of two ferromagnetic layers F-1 and F-2 coupled by RKKY exchange coupling. When the magnetic moment of the outer layer F-2 dominates the magnetization of the SyF, the sign of the effective spin torque exerted on the layer F-1 is controlled by the coupling's strength: for weak coupling the spin torque tends to antialign F-1's magnetization with respect to the pinned layer F-0. At large coupling the situation is reversed and tends to align F-1 with respect to F-0. At intermediate coupling, numerical simulations reveal that the competition between these two incompatible limits leads generically to spin torque oscillator (STO) behavior. The STO is found at zero magnetic field, with very significant amplitude of oscillations and frequencies up to 50 GHz or higher. [less ▲]

Background. This study investigated the relationship between phonological and syntactic disorders of French-speaking children with SLI in production. Aims. This article compares three theories (pure phonological theory, surface theory and mapping theory) of language developmental disorders, all of which view phonological difficulties as the main reason for the children’s problems. Methods and procedures. The linguistic parameters (salience, phonological complexity, syntactic complexity, lexical/functional, semantic/syntactic) (that are fundamental) to these theories were identified. The validity of these parameters was then tested against the phonological and syntactic results obtained by children with SLI and control children. Nine syntactic categories were tested. Outcomes and results. Phonological complexity was the only parameter whose importance was confirmed, and this was only for phonological results. Syntactic complexity did not correlate significantly with children’s difficulties, and the importance of phonological salience was not confirmed for French-speaking children. Mixed results were obtained for the other parameters, including negative correlations, which may call for different explanations. Conclusions. No theory fully explained the observed outcomes. Pure phonological theory was the most parsimonious, but could not explain all the results. [less ▲]

Humans are less responsive to the surrounding environment during sleep. However, the extent to which the human brain responds to external stimuli during sleep is uncertain. We used simultaneous EEG and functional MRI to characterize brain responses to tones during wakefulness and non-rapid eye movement (NREM) sleep. Sounds during wakefulness elicited responses in the thalamus and primary auditory cortex. These responses persisted in NREM sleep, except throughout spindles, during which they became less consistent. When sounds induced a K complex, activity in the auditory cortex was enhanced and responses in distant frontal areas were elicited, similar to the stereotypical pattern associated with slow oscillations. These data show that sound processing during NREM sleep is constrained by fundamental brain oscillatory modes (slow oscillations and spindles), which result in a complex interplay between spontaneous and induced brain activity. The distortion of sensory information at the thalamic level, especially during spindles, functionally isolates the cortex from the environment and might provide unique conditions favorable for off-line memory processing.
