    OBJECTIVES: To determine the role of skin and subcutaneous space closure in caesarean section on the cosmetic appearance of the scar and the patients' satisfaction. STUDY DESIGN: 153 patients undergoing caesarean section without prior abdominal delivery were included and randomly assigned in a non-blinded study to four different combinations of skin and subcutaneous tissue closure. The scar was assessed after a period of at least 4 months by a self-developed protocol and the patient was asked to complete a survey regarding her satisfaction with the scar. RESULTS: One hundred patients were eligible for long-term evaluation of the scar. Skin closure by either staples or intracutaneous suture in combination with closure or non-closure of the subcutaneous space has a comparable outcome in view of cosmetic outcome and patient satisfaction. CONCLUSIONS: All four methods of skin closure seem to be a reasonable choice in caesarean section because they have comparable cosmetic outcome, do not differ with respect to the patients' satisfaction and bear comparable costs

    Inactivation de la thrombine par l'urine humaine normale.

    Les urines humaines normales inactivent immédiatement la thrombine ajoutée quand leur pH est acide ou au moindre degré quand leur pH est a1calin. Quand le pH d'urine est neutral ou légerement alcalin l'inactivation de thrombine est faible ou s'annule. Après une incubation de 10 et 20 minutes de l'urine avec la thrombine l'inactivation ne subit pas de changements essentiaux. Les résultats obtenus in vitro démontrent que l'alcalinisation d'urine a l'aide d'une diète appropri&#233;s ou des remèdes pharmacologiques peuvent favorablement influencer les hémorragies imminentes ou d&#233;ja existantes du systeme urinaire.</p

    Decoherence-Free Quantum Information Processing with Four-Photon Entangled States

    Full text link
    Decoherence-free states protect quantum information from collective noise, the predominant cause of decoherence in current implementations of quantum communication and computation. Here we demonstrate that spontaneous parametric down-conversion can be used to generate four-photon states which enable the encoding of one qubit in a decoherence-free subspace. The immunity against noise is verified by quantum state tomography of the encoded qubit. We show that particular states of the encoded qubit can be distinguished by local measurements on the four photons only.Comment: 4 pages, 4 eps figures, revtex

    A espécie Heteropterys aphrodisíaca O. Mach (Nó -de-cachorro) é tida como planta medicinal de grande importância devido as suas atribuições curativas de enfermidades. Contudo, a parte fitotécnica ainda é pouco estudada. O objetivo do trabalho foi analisar os teores de sódio (Na), potássio (K), fósforo (P), magnésio (Mg), cálcio (Ca), manganês (Mn), ferro (Fe), nitrogênio total (NT) e proteína bruta (PB) nas folhas de mudas de Heteropterys aphrodisíaca O.

    Ghosts of the past and dreams of the future: the impact of temporal focus on responses to contextual ingroup devaluation.

    addresses: University of Exeter, Exeter, UK. [email protected]: Journal Article; Research Support, Non-U.S. Gov'tCopyright © 2012 SAGE Publications. Author's draft version; post-print. Final version published by Sage available on Sage Journals Online http://online.sagepub.com/The authors investigated the impact of temporal focus on group members' responses to contextual ingroup devaluation. Four experimental studies demonstrated that following an induction of negative ingroup evaluation, participants primed with a past temporal focus reported behavioral intentions more consistent with this negative appraisal than participants primed with a future temporal focus. This effect was apparent only when a negative (but not a positive) evaluation was induced, and only among highly identified group members. Importantly, the interplay between temporal focus and group identification on relevant intentions was mediated by individual self-esteem, suggesting that focus on the future may be conducive to separating negative ingroup appraisals from individual self-evaluations. Taken together, the findings suggest that high identifiers' responses to ingroup evaluations may be predicated on their temporal focus: A focus on the past may lock such individuals within their group's history, whereas a vision of the future may open up opportunities for change

    Investigating Metal-Mediated DNA Damage Prevention by Antioxidants and Examining the Role of Metals in Fluconazole-Mediated DNA Damage

    Get PDF
    Reactive oxygen species (ROS) play an important role in the development of many diseases. Common assays to test the ability of hydrophobic compounds to prevent oxidative stress are radical scavenging assays and cell studies. However, these radical assays often do not accurately reflect biological outcomes, and the use of different cell lines limits the ability to directly compare compound efficacy (Chapter 1). Results from DNA damage prevention assays can directly compare antioxidant efficacy, but these assays have been limited to water-soluble compounds. Chapter 2 discusses the first assay that quantifiably evaluates the ability of hydrophobic compounds to prevent metal-mediated DNA damage inhibition via gel electrophoresis. This assay allows biologically relevant evaluation of compounds for their effectiveness under consistent conditions. The glutathione peroxidase mimic ebselen and its derivatives prevent copper-mediated DNA damage (IC50 values 280-450 µM), but do not significantly inhibit iron-mediated DNA damage. In combination with radical scavenging assays, these biologically relevant assays enable identification of structure-function relationships for hydrophobic antioxidant compounds and drugs. Studies presented in Chapter 3 investigate the effect of metal binding on drug properties. Fluconazole (FLC) binds both iron and copper, and stabilizes Cu+ and Fe2+ over Cu2+ and Fe3+, respectively, as measured by cyclic voltammetry. Using gel electrophoresis assays, the effects of FLC on copper- and iron-mediated DNA damage were determined. FLC does not cause DNA damage by itself, but addition of FLC lowers the concentration of Fe2+ or Cu+ needed to cause 50% DNA damage (EC50) by 50 and 40 %, respectively, increasing reactive oxygen species production. The studies described in Chapter 4 investigate the antioxidant capabilities of a series of plant-derived, procyanidin-rich condensed tannins (CTs) with different structural features for their ability to inhibit copper (IC50 162.5 ± 0.3 µM to 27% DNA damage inhibition at the highest concentration) and iron-mediated (IC50 0.75 ± 0.01 to 4.96 ± 0.01 µM) DNA damage. The activity of CTs are compared to six commercially available polyphenolic compounds. This is the first study to investigate structure-activity relationships for CTs and their abilities to prevent metal-mediated DNA damage

    Using self-definition to predict the influence of procedural justice on organizational, interpersonal, and job/task-oriented citizenship behaviors

    Get PDF
    An integrative self-definition model is proposed to improve our understanding of how procedural justice affects different outcome modalities in organizational behavior. Specifically, it is examined whether the strength of different levels of self-definition (collective, relational, and individual) each uniquely interact with procedural justice to predict organizational, interpersonal, and job/task-oriented citizenship behaviors, respectively. Results from experimental and (both single and multisource) field data consistently revealed stronger procedural justice effects (1) on organizational-oriented citizenship behavior among those who define themselves strongly in terms of organizational characteristics, (2) on interpersonal-oriented citizenship behavior among those who define themselves strongly in terms of their interpersonal relationships, and (3) on job/task-oriented citizenship behavior among those who define themselves weakly in terms of their distinctiveness or uniqueness. We discuss the relevance of these results with respect to how employees can be motivated most effectively in organizational settings
