Emotional processing in a ten-session general psychiatric treatment for borderline personality disorder: a case study.

This study examines the effects of a borderline-specific treatment, called general psychiatric management, on emotional change, outcome and therapeutic alliance of an outpatient presenting with borderline personality disorder. Based on the sequential model of emotional processing, emotional states were assessed in a 10-session setting. The case showed an increase in expressions of distress and no change in therapeutic alliance and tended towards general deterioration. Results suggest emotional processing may play a lesser role in general psychiatric management in early phase treatment than previously hypothezised. Copyright © 2015 John Wiley & Sons, Ltd.

Content validation of the nursing diagnosis Nausea

This study aimed to evaluate the content validity of the nursing diagnosis of nausea in the immediate post-operative period, considering Fehring’s model. Descriptive study with 52 nurses experts who responded an instrument containing identification and validation of nausea diagnosis data. Most experts considered the domain 12 (Comfort), Class 1 (Physical Comfort) and the statement (Nausea) adequate to the diagnosis. Modifications were suggested in the current definition of this nursing diagnosis. Four defining characteristics were considered primary (reported nausea, increased salivation, aversion to food and vomiting sensation) and eight secondary (increased swallowing, sour taste in the mouth, pallor, tachycardia, diaphoresis, sensation of hot and cold, changes in blood pressure and pupil dilation). The total score for the diagnosis of nausea was 0.79. Reports of nausea, vomiting sensation, increased salivation and aversion to food are strong predictors of nursing diagnosis of nausea.

Auditory motion affects visual biological motion processing.

The processing of biological motion is a critical, everyday task performed with remarkable efficiency by human sensory systems. Interest in this ability has focused to a large extent on biological motion processing in the visual modality (see, for example, Cutting, J. E., Moore, C., & Morrison, R. (1988). Masking the motions of human gait. Perception and Psychophysics, 44(4), 339-347). In naturalistic settings, however, it is often the case that biological motion is defined by input to more than one sensory modality. For this reason, here in a series of experiments we investigate behavioural correlates of multisensory, in particular audiovisual, integration in the processing of biological motion cues. More specifically, using a new psychophysical paradigm we investigate the effect of suprathreshold auditory motion on perceptions of visually defined biological motion. Unlike data from previous studies investigating audiovisual integration in linear motion processing [Meyer, G. F. & Wuerger, S. M. (2001). Cross-modal integration of auditory and visual motion signals. Neuroreport, 12(11), 2557-2560; Wuerger, S. M., Hofbauer, M., & Meyer, G. F. (2003). The integration of auditory and motion signals at threshold. Perception and Psychophysics, 65(8), 1188-1196; Alais, D. & Burr, D. (2004). No direction-specific bimodal facilitation for audiovisual motion detection. Cognitive Brain Research, 19, 185-194], we report the existence of direction-selective effects: relative to control (stationary) auditory conditions, auditory motion in the same direction as the visually defined biological motion target increased its detectability, whereas auditory motion in the opposite direction had the inverse effect. Our data suggest these effects do not arise through general shifts in visuo-spatial attention, but instead are a consequence of motion-sensitive, direction-tuned integration mechanisms that are, if not unique to biological visual motion, at least not common to all types of visual motion. Based on these data and evidence from neurophysiological and neuroimaging studies we discuss the neural mechanisms likely to underlie this effect.

Activity assays and immunoassays for plasma Renin and prorenin: information provided and precautions necessary for accurate measurement.

BACKGROUND: Measurement of plasma renin is important for the clinical assessment of hypertensive patients. The most common methods for measuring plasma renin are the plasma renin activity (PRA) assay and the renin immunoassay. The clinical application of renin inhibitor therapy has thrown into focus the differences in information provided by activity assays and immunoassays for renin and prorenin measurement and has drawn attention to the need for precautions to ensure their accurate measurement. CONTENT: Renin activity assays and immunoassays provide related but different information. Whereas activity assays measure only active renin, immunoassays measure both active and inhibited renin. Particular care must be taken in the collection and processing of blood samples and in the performance of these assays to avoid errors in renin measurement. Both activity assays and immunoassays are susceptible to renin overestimation due to prorenin activation. In addition, activity assays performed with peptidase inhibitors may overestimate the degree of inhibition of PRA by renin inhibitor therapy. Moreover, immunoassays may overestimate the reactive increase in plasma renin concentration in response to renin inhibitor therapy, owing to the inhibitor promoting conversion of prorenin to an open conformation that is recognized by renin immunoassays. CONCLUSIONS: The successful application of renin assays to patient care requires that the clinician and the clinical chemist understand the information provided by these assays and of the precautions necessary to ensure their accuracy.

Instrument for assessing the quality of mobile emergency pre-hospital care: content validation

OBJECTIVES To validate an instrument to assess quality of mobile emergency pre-hospital care. METHOD A methodological study where 20 professionals gave their opinions on the items of the proposed instrument. The analysis was performed using Kappa test (K) and Content Validity Index (CVI), considering K> 0.80 and CVI ≥ 0.80. RESULTS Three items were excluded from the instrument: Professional Compensation; Job Satisfaction and Services Performed. Items that obtained adequate K and CVI indexes and remained in the instrument were: ambulance conservation status; physical structure; comfort in the ambulance; availability of material resources; user/staff safety; continuous learning; safety demonstrated by the team; access; welcoming; humanization; response time; costumer privacy; guidelines on care; relationship between professionals and costumers; opportunity for costumers to make complaints and multiprofessional conjunction/actuation. CONCLUSION The instrument to assess quality of care has been validated and may contribute to the evaluation of pre-hospital care in mobile emergency services.

Reduction of connexin36 content by ICER-1 contributes to insulin-secreting cells apoptosis induced by oxidized LDL particles.

Connexin36 (Cx36), a trans-membrane protein that forms gap junctions between insulin-secreting beta-cells in the Langerhans islets, contributes to the proper control of insulin secretion and beta-cell survival. Hypercholesterolemia and pro-atherogenic low density lipoproteins (LDL) contribute to beta-cell dysfunction and apoptosis in the context of Type 2 diabetes. We investigated the impact of LDL-cholesterol on Cx36 levels in beta-cells. As compared to WT mice, the Cx36 content was reduced in islets from hypercholesterolemic ApoE-/- mice. Prolonged exposure to human native (nLDL) or oxidized LDL (oxLDL) particles decreased the expression of Cx36 in insulin secreting cell-lines and isolated rodent islets. Cx36 down-regulation was associated with overexpression of the inducible cAMP early repressor (ICER-1) and the selective disruption of ICER-1 prevented the effects of oxLDL on Cx36 expression. Oil red O staining and Plin1 expression levels suggested that oxLDL were less stored as neutral lipid droplets than nLDL in INS-1E cells. The lipid beta-oxidation inhibitor etomoxir enhanced oxLDL-induced apoptosis whereas the ceramide synthesis inhibitor myriocin partially protected INS-1E cells, suggesting that oxLDL toxicity was due to impaired metabolism of the lipids. ICER-1 and Cx36 expressions were closely correlated with oxLDL toxicity. Cx36 knock-down in INS-1E cells or knock-out in primary islets sensitized beta-cells to oxLDL-induced apoptosis. In contrast, overexpression of Cx36 partially protected INS-1E cells against apoptosis. These data demonstrate that the reduction of Cx36 content in beta-cells by oxLDL particles is mediated by ICER-1 and contributes to oxLDL-induced beta-cell apoptosis.

Engineering polyhydroxyalkanoate content and monomer composition in the oleaginous yeast Yarrowia lipolytica by modifying the ß-oxidation multifunctional protein.

Recombinant strains of the oleaginous yeast Yarrowia lipolytica expressing the PHA synthase gene (PhaC) from Pseudomonas aeruginosa in the peroxisome were found able to produce polyhydroxyalkanoates (PHA). PHA production yield, but not the monomer composition, was dependent on POX genotype (POX genes encoding acyl-CoA oxidases) (Haddouche et al. FEMS Yeast Res 10:917-927, 2010). In this study of variants of the Y. lipolytica β-oxidation multifunctional enzyme, with deletions or inactivations of the R-3-hydroxyacyl-CoA dehydrogenase domain, we were able to produce hetero-polymers (functional MFE enzyme) or homo-polymers (with no 3-hydroxyacyl-CoA dehydrogenase activity) of PHA consisting principally of 3-hydroxyacid monomers (>80%) of the same length as the external fatty acid used for growth. The redirection of fatty acid flux towards β-oxidation, by deletion of the neutral lipid synthesis pathway (mutant strain Q4 devoid of the acyltransferases encoded by the LRO1, DGA1, DGA2 and ARE1 genes), in combination with variant expressing only the enoyl-CoA hydratase 2 domain, led to a significant increase in PHA levels, to 7.3% of cell dry weight. Finally, the presence of shorter monomers (up to 20% of the monomers) in a mutant strain lacking the peroxisomal 3-hydroxyacyl-CoA dehydrogenase domain provided evidence for the occurrence of partial mitochondrial β-oxidation in Y. lipolytica.

Characterization of NALP2 and NALP3 IL-1β processing inflammasomes

Résumé II y a cinq ans, la découverte d'un nouveau domaine, le PYD domaine, lié aux domaines de la mort, a permis la description de la nouvelle famille des NALP protéines. L'analyse structurelle de cette famille de protéines révéla la présence de deux autres domaines, impliqués dans l'oligomerisation, NACHT, et la détection des ligands, Leucine rich repeats ou LRR. Cette architecture protéique est homologue à celle qui est décrite pour les NODs, les Tol1 récepteurs et tes protéines de résistance chez les plantes. Cette homologie suggère une possible implication des NALPs dans la régulation de l'immunité innée. Premièrement, nous avons décrit les composants minimaux qui permettent à l'inflammasomeNALP3 d'activer la caspase pro-inflammatoire, caspase-1. En comparaison à NALP1, NALP3 ne contient pas de FIIND domaine, ni de CARD domaine en C-terminus et n'interagit pas avec caspase-5. Nous avons découvert une protéine très homologue au C-terminus de NALP1, Cardinal, qui se lie au NACHT domaine de NALP2 et NALP3 par l'intermédiaire de son FIIND domaine. Cardinal possède la capacité d'interagir avec caspase-l, mais seul ASC semble être nécessaire à la maturation de la prointerleukine-1β suite à la stimulation de NALP3. Deuxièmement, notre étude s'est concentrée sur la nature du stimulus capable d'induire la formation et l'activation de l'inflammasome-NALP3. Nous avons démontré que l'ajout de muramyl dipeptide (MDP), produit à partir de la digestion enzymatique de peptidoglycaris bactériens, induit à la fois l'expression de la proIL-1β par la voie NOD2 et sa maturation en IL-1β active par la voie NALP3. Bien que le MDP active l'inflammasome-NALP3, il est incapable d'induire la sécrétion de l'IL-1β mature dans la lignée cellulaire THP1, comparé aux monocytes primaires humains. Cette différence pourrait être liée à l'absence, dans les THP1, de la protéine Filamin, qui est proposée d'interagir avec Cardinal. L'implication de NALP3 dans la maturation de l'IL-lb est confirmée suite à la découverte de mutations sur le gène CIAS1/NALP3/cryopyrin associées à trois maladies auto-inflammatoires : le syndrome de Muckle-Wells (MWS), l'urticaire familial au froid (FCU) et le syndrome CINCA/NOMID. Une élévation constitutive de la maturation et de la sécrétion de la proIL-1β en absence de stimulation MDP est détectée dans les macrophages des patients Muckle-Wells. En conclusion, nos études ont démontré que l'inflammasome-NALP3 doit être finement régulé pour éviter une activité incontrôlée qui représente la base moléculaire des symptômes associés aux syndromes auto-inflammatoires liés à NALP3. Summary Five years ago, the description of the NALP family originated from the discovery of a new death-domain fold family, the PYD domain. NALP contains aprotein-protein interaction domain (PYD), an oligomerization domain (NACHT) and a ligand-sensing domain, leucine rich repeats or LRR. This protein architecture shares similarity with receptors involved in immunity, such as NODS, Toll receptors (TLRs) and related plant resistance proteins, and points to an important role of NALPs in defense mechanisms. We first described the minimal complex involved in the pro-inflammatory Interleukin-1beta (IL-1β) cytokine maturation, called the inflammasome, which contains NALP3. In contrast to NALP1, NALP3, like other members of the NALP family, is devoid of C-terminal FIIND and CARD domains and does not interact with the pro-inflammatory caspase-5. Interestingly, a homolog of the C-terminal portion of NALP1 was found in the human genome and was named Cardinal. We found that NALP2 and NALP3 interact with the CARD-containing proteins Cardinal. Cardinal is able to bind to caspase-1 but is not required for IL-1β maturation through NALP3 activation, as demonstrated for the adaptor ASC. Secondly, our study focused on the stimuli involved in the activation of the NALP3 inflammasome. MDP was shown to induce the expression of proIL1β through NOD2 and then the maturation into active IL-1β by activation of the NALP3 inflammasome. However, in the monocytic THP1 cell line, secretion of IL-1β upon MDP stimulation seems to be independent of the inflammasome activation compared to human primary monocytes. This difference might be linked to a Cardinal-interacting protein, filamin. Until now, the role of Cardinal and filamin is still unknown and remains to be elucidated. Finally, mutations in the NALP3/cryopyrin/CIAS1 gene are associated with three autoinflammatory diseases: Muckle-Wells syndrome, familial cold autoinflammatory syndrome, and CINCA. Constitutive, elevated IL-1β maturation and secretion, even in the absence of MDP stimulation, was observed in macrophages from Muckle-Wells patients and confirmed a key role for the NALP3 inflammasome in innate immunity In conclusion, our studies describes the formation of the NALP3 inflammasome and suggests that this complex has to be tightly regulated to avoid an increased deregulated inflammasome activity that is the molecular basis for the symptoms associated with NALP3-dependent autoinflammatory disorders.

The role of awareness, information gathering and processing in school choice

This paper studies the determinants of school choice, focusing on the role of information. Weconsider how parents' search efforts and their capacity to process information (i.e., tocorrectly assess schools) affect the quality of the schools they choose for their children. Usinga novel dataset, we are able to identify parents' awareness of schools in their neighborhoodand measure their capacity to rank the quality of the school with respect to the officialrankings. We find that parents education and wealth are important factors in determiningtheir level of school awareness and information gathering. Moreover, these search effortshave important consequences in terms of the quality of school choice.

Dexamethasone induces posttranslational degradation of GLUT2 and inhibition of insulin secretion in isolated pancreatic beta cells. Comparison with the effects of fatty acids.

GLUT2 expression is strongly decreased in glucose-unresponsive pancreatic beta cells of diabetic rodents. This decreased expression is due to circulating factors distinct from insulin or glucose. Here we evaluated the effect of palmitic acid and the synthetic glucocorticoid dexamethasone on GLUT2 expression by in vitro cultured rat pancreatic islets. Palmitic acid induced a 40% decrease in GLUT2 mRNA levels with, however, no consistent effect on protein expression. Dexamethasone, in contrast, had no effect on GLUT2 mRNA, but decreased GLUT2 protein by about 65%. The effect of dexamethasone was more pronounced at high glucose concentrations and was inhibited by the glucocorticoid antagonist RU-486. Biosynthetic labeling experiments revealed that GLUT2 translation rate was only minimally affected by dexamethasone, but that its half-life was decreased by 50%, indicating that glucocorticoids activated a posttranslational degradation mechanism. This degradation mechanism was not affecting all membrane proteins, since the alpha subunit of the Na+/K+-ATPase was unaffected. Glucose-induced insulin secretion was strongly decreased by treatment with palmitic acid and/or dexamethasone. The insulin content was decreased ( approximately 55 percent) in the presence of palmitic acid, but increased ( approximately 180%) in the presence of dexamethasone. We conclude that a combination of elevated fatty acids and glucocorticoids can induce two common features observed in diabetic beta cells, decreased GLUT2 expression, and loss of glucose-induced insulin secretion.

Bilateral dorsal and ventral fiber pathways for the processing of affective prosody identified by probabilistic fiber tracking.

Dorsal and ventral pathways for syntacto-semantic speech processing in the left hemisphere are represented in the dual-stream model of auditory processing. Here we report new findings for the right dorsal and ventral temporo-frontal pathway during processing of affectively intonated speech (i.e. affective prosody) in humans, together with several left hemispheric structural connections, partly resembling those for syntacto-semantic speech processing. We investigated white matter fiber connectivity between regions responding to affective prosody in several subregions of the bilateral superior temporal cortex (secondary and higher-level auditory cortex) and of the inferior frontal cortex (anterior and posterior inferior frontal gyrus). The fiber connectivity was investigated by using probabilistic diffusion tensor based tractography. The results underscore several so far underestimated auditory pathway connections, especially for the processing of affective prosody, such as a right ventral auditory pathway. The results also suggest the existence of a dual-stream processing in the right hemisphere, and a general predominance of the dorsal pathways in both hemispheres underlying the neural processing of affective prosody in an extended temporo-frontal network.
