No full textMaria Pia Donato, Cultura dell'antico e cultura dei Lumi a Roma nel Settecento : la politicizzazione dello scambio culturale durante il pontificato di Pio VI, p. 503-548.
Il pontificato di Pio VI Braschi (1775-1798) fu un'età fervida di promesse riformatrici e di fermenti culturali caratterizzati dal culto dell'Antichità.
Con il deteriorarsi della situazione economica e politica questa ammirazione degli Antichi si trasformò progressivamente in un atteggiamento critico, fino agli esiti rivoluzionari del 1798-99, quando una parte delle élites, educate nella classicità, dimostrò con l'adesione alla Repubblica giacobina Romana il distacco dalla monarchia cattolica. Analizzando la pubblicistica, la sociabilità culturale, la biografia collettiva di molti intellettua-

Variazioni semiotiche. Analisi Interpretazioni Metodi a confronto
No full textIn questo volume, curato da M:P. Pozzato si confrontano diversi approcci semiotici di analisi. Esempi trattati: un racconto di Calvino, cinque barzettelle a tema ebraico, un film di N. Shaymalan. Il volume è scritto in gran parte da Maria Pia Pozzato (circa 120 pagine su 170) la quale, oltre a condurre le proprie analisi, cura il raccordo fra i diversi approcci
Engel structures on complex surfaces
No full textWe classify complex surfaces (M,J) admitting Engel structures D which are complex line bundles. Namely, we prove that this happens if and only if (M,J) has trivial Chern classes. We construct examples of such Engel structures by adapting a construction due to Geiges [7]. We also study associated Engel defining forms and define a unique splitting of TM associated with D J-Engel
Estudio de la presión intraabdominal en pacientes crÃticos sin afección abdominal
No full textEl aumento de la presión intraabdominal predice la ocurrencia de complicaciones en el paciente quirúrgico grave, por lo que constituye un elemento insustituible para su diagnóstico y tratamiento. En nuestro estudio nos propusimos identificar el comportamiento de esta variable medida por el método transvesical en pacientes sin afección abdominal ni sobrecarga previa de líquido. Para ello, se realizó su medición a un grupo de 100 pacientes críticos atendidos en cuatro unidades de Cuidados Intensivos de la Ciudad de la Habana y a un grupo control de 50 pacientes ambulatorios sin antecedentes de patología abdominal reciente con cistometrías normales atendidos en la consulta de Urodinamia del CIMEQ. La presión intraabdominal en los pacientes críticos fue de 5.13+/-3.73 y en el grupo control de 1.56+/-1.27 mm de Hg. La presión intraabdominal fue mayor en los pacientes del sexo masculino, ventilados, y con mayor índice de masa corporal, estos datos fueron estadísticamente significativos. La demostración de que existen valores basales de PIA para los pacientes críticos más elevados que los generalmente aceptados permite aumentar la sensibilidad diagnóstica del método y sugiere la necesidad de monitorizar estrechamente la PIA en todos los pacientes críticos
Multiple activities of a multifaceted receptor: roles of cleaved and soluble uPAR.
No full textThe urokinase-type plasminogen activator receptor (uPAR) is a GPI-anchored cell-surface receptor involved in many physiological and pathological events that include cell migration and tissue invasion. uPAR traditional role was considered the focusing of uPA proteolytic activity on the cell surface; however, different uPAR activities have been demonstrated in the last years. In fact, cell surface uPAR functionally interacts with integrins, fMLP-receptors (fMLP-Rs) and growth factor receptors, thus regulating cell adhesion, migration and proliferation. uPAR also exists in a soluble form (suPAR) that has been detected in human body fluids. Both cell surface and suPAR can be proteolytically cleaved, thus generating truncated forms lacking the N-terminal domain and exposing the specific sequence able to interact with the fMLP-Rs. The cleaved form of suPAR binds and activates the fMLP-Rs and regulates the activity of MCP-1, RANTES and SDF1 receptors. Here, we review the role that shedding and cleavage could play in regulating uPAR structural/functional interaction with other cell-surface receptors and in uPAR-mediated biological and pathological processes
Confocal microscopy of biofilms stained with PIA/PNAG-specific antibodies.
No full textNon-mucoid strain (A) and mucoid (B) S. aureus strains (strains 8.1 and 8.2) were grown overnight in TSB. After washing, adherent bacteria were stained using SYTO 9 (green). PIA/PNAG was detected using ALEXA-568 labeled wheat germ agglutinin (red), which is a lectin binding to the N-acetylglucosaminyl backbone of PIA/PNAG. Zoom-in shows PIA/PNAG-embedded bacteria in the mucoid strain (B), while hardly any PIA/PNAG is detected with the non-mucoid isolate. White bar = 10 μm.</p
<sup>15</sup>N-HSQC spectra of (A) AVR-Pia and (B) AVR1-CO39.
No full text<p>In the 15N-HSQC spectra of (A) AVR-Pia and (B) AVR1-CO39, each peak comes from N-H chemical connectivity and has <sup>15</sup>N and <sup>1</sup>H chemical shift coordinates. There is one backbone N-H group per residue, leading to one HSQC peak per residue. A side-chain NH<sub>2</sub> group gives two HSQC peaks with one common N coordinate. Other side-chains NH groups may also be observed, as Trp Nε1-H and Arg Nε-H. (*) indicates residues in the N-terminal tail. The mature proteins start at residue Ala20 and Trp23 for AVR-Pia and AVR1-CO39, respectively [<a href="http://www.plospathogens.org/article/info:doi/10.1371/journal.ppat.1005228#ppat.1005228.ref026" target="_blank">26</a>,<a href="http://www.plospathogens.org/article/info:doi/10.1371/journal.ppat.1005228#ppat.1005228.ref032" target="_blank">32</a>]. The NH<sub>2</sub> side chains resonances were assigned. The resonances of the tryptophan indole groups are specifically labelled Hε1.</p
A Multi-Language Comparison of Influences on Author Verification using Character N-Grams
No full textWe create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Stegomyia mosquitoes in Mayotte, taxonomic study and description of Stegomyia pia n. sp.
No full textFour mosquito species, including a new species of the genus Stegomyia, are reported from Mayotte in the western Indian Ocean. The most abundant species were Stegomyia aegypti and St. albopicta. Only one species of the St. simpsoni group was observed, St. bromeliae. The fourth species is Stegomyia pia Le Goff & Robert n. sp. of which the larva, pupa, male and female are here described. The larval stages of St. pia n. sp. are morphologically similar to St. aegypti but differ in the number of branches of the seta 1-X; the adult is morphologically distinct for a number of characters, for instance the scutal ornamentation. Stegomyia pia n. sp. is uncommon but not rare, and largely distributed across Mayotte. Its larval habitats are natural and diverse including rock pools, tree holes, and cut and severed bamboos. The biology of adults remains unknown, especially female biting behaviour. Both morphological characters and nucleotide sequences of the ITS2 and COI genes indicate that this species is best placed in the genus Stegomyia. Dichotomous keys to the four species of Mayotte Stegomyia are presented for adults and fourth-instar larvae. The potential vector role of these mosquitoes is hypothesised. This paper underlines advances in knowledge of the biodiversity in the French overseas departments and territories
