La variable 'sexe' en les llengües del món
2013
El sexe és una de les variables més freqüents en els diferents recursos lingüístics per a identificar els interlocutors en les llengües del món. El fet que s'hagi confós el gènere gramatical (procediment de classificació dels substantius) amb el sexe, i la consegüent inclusió dels elements identificadors en la categoria «gènere», ha provocat una certa confusió sobre la naturalesa d'aquests fenòmens. En l'article es proposa una classificació en quatre tipus dels mecanismes per a la identificació dels interlocutors en la llengua, per bé que tots poden ser entesos com a part d'un continu que va des dels elements gramaticals obligatoris fins als lectes específics per a homes i dones. Entremig, …
El gest i la dixi d'espai en textos instructius
2009
La dixi és normalment concebuda, des del punt de vista lingüístic, com un fenomen que mostra la relació entre els trets estructurals del llenguatge i el context específic de comunicació. Hi ha mecanismes no verbals que també actuen com a recursos díctics en moltes situacions de la llengua oral. És per aquesta raó que calen estudis que analitzin diferents aspectes de la combinació d’aquests diferents mecanismes. L’objectiu d’aquesta proposta és analitzar la relació entre la verbalització dels díctics d’espai trobats en els textos instructius del projecte PRAGMAESTIL i els elements no verbals que els acompanyen. Concretament, s’observarà en primer lloc si els díctics van acompanyats de gestos…
Autobiographical texts written by learners of Catalan as an Additional Language: From formative needs to reflection in the teaching of narrative genr…
2022
In this article we analyse autobiographical narrative texts written by university students studying Catalan as an Additional Language at a CEFR (2020) B1 level. The goal is to analyse the formative needs related to the writing of this genre in order to foster metadiscursive reflection in the classroom that will allow students to improve their written output. To this end, we analyzed a corpus of 39 autobiographies at both the macrotextual level (i.e., rhetorical moves) and the microtextual level (i.e., deictic elements which channel the narrative’s organization). Our results show that the problems that these texts present for students are related to awareness of the elements that define the …
Precise Somatotopic Thalamocortical Axon Guidance Depends on LPA-Mediated PRG-2/Radixin Signaling
2016
Summary Precise connection of thalamic barreloids with their corresponding cortical barrels is critical for processing of vibrissal sensory information. Here, we show that PRG-2, a phospholipid-interacting molecule, is important for thalamocortical axon guidance. Developing thalamocortical fibers both in PRG-2 full knockout (KO) and in thalamus-specific KO mice prematurely entered the cortical plate, eventually innervating non-corresponding barrels. This misrouting relied on lost axonal sensitivity toward lysophosphatidic acid (LPA), which failed to repel PRG-2-deficient thalamocortical fibers. PRG-2 electroporation in the PRG-2−/− thalamus restored the aberrant cortical innervation. We ide…
Resistance to third-generation cephalosporins in Escherichia coli in the French community: The times they are a-changin'?
2020
Since the early 2000s, Escherichia coli resistance to third-generation cephalosporins (3GCs) has been increasing in all European countries, mainly due to the spread of extended spectrum β-lactamases (ESBLs). Here we present a retrospective study that combines resistance of E. coli to 3GCs and quinolones with data on antibiotic use in the community in a region of Northeastern France.Since 2012, an observational surveillance of antimicrobial resistance and antibiotic use in the community was conducted: data on antimicrobial resistance in E. coli isolates were collected from 11 private laboratories, and consumption data were collected from the three main healthcare insurances.A significant dec…
Emotivity in Valencian demonstratives
2022
Més que una proximitat metafòrica cap al referent, la dixi emotiva, afectiva o empàtica produeix proximitat cap a l’oient arran de l’atenció conjunta i/o l’avaluació del referent. Aquest treball estudia els usos del demostratiu (com ara, la funció nominal o adverbial, el grau, el mode referencial, el caràcter humà, etc.) i de les seues construccions (anteposades al nom, posposades al nom o sense nucli nominal) per a comprovar quin tipus de demostratius tendeixen a tindre referents que són valorats de manera positiva o negativa. Per a realitzar aquesta exploració, hem recollit 383 formes demostratives d’un corpus propi (CoValC) format per converses col·loquials entre valencianoparlants de di…
ComparativeIn Vitroevaluation of cumulative release of the urinary antiseptics Nalidixic acid, Pipemidic acid, Cinoxacin, and norfloxacin from white …
1994
AbstractThe in vitro diffusion of nalidixic acid (1), pipemidic acid (2), cinoxacin (3), and norfloxacin (4) was studied. The transfer rate constants (kd) from simulated gastro-intestinal juices to simulated plasma, throughout artificial wall lipid membranes, were defined. The kd values suggested that the four drugs are absorbed both in gastric and intestinal environments in similar amounts. To obtain lack of gastric unwanted effects white beeswax microspheres containing 1, 2, 3, and 4 were investigated as a vehicle for the drug intestinal release; they were prepared by the meltable dispersion process using wetting agents. Discrete, reproducible free flowing microspheres were obtained. The …
Pathogenic microorganisms carried by migratorybirds passing through the territory of the island ofUstica, Sicily (Italy)
2011
Several studies have shown that migratory birds play an important role in the ecology, circulation and dissemination of pathogenic organisms. In October 2006, a health status evaluation was performed on a large population of migratory birds passing through the territory of Ustica (Italy), an island located on the migration route of many species of birds to Africa, and various laboratory tests were conducted. In total, 218 faecal swabs and the internal organs of 21 subjects found dead in nets were collected for bacteriological and virological examination, including avian influenza and Newcastle disease. In addition, 19 pooled fresh faecal samples were collected for mycological examination. T…
Identification and relevance of the CD95-binding domain in the N-terminal region of ezrin.
2003
The CD95 (Fas/APO-1) linkage to the actin cytoskeleton through ezrin is an essential requirement for susceptibility to the CD95-mediated apoptosis in CD4+ T cells. We have previously shown that moesin was not involved in the binding to CD95. Here we further support the specificity of the ezrin/CD95 binding, showing that radixin did not bind CD95. The ezrin region specifically and directly involved in the binding to CD95 was located in the middle lobe of the ezrin FERM domain, between amino acids 149 and 168. In this region, ezrin, radixin, and moesin show 60-65% identity, as compared with the 86% identity in the whole FERM domain. Transfection of two different human cell lines with a green …
Plasmid-mediated QnrS2 determinant from a clinical Aeromonas veronii isolate.
2008
The main objective of this study was to determine the prevalence of the Qnr determinants in clinical and environmental Aeromonas spp. A total of 52 Aeromonas sp. isolates identified by biochemical methods (5), 25 isolated from natural waters (1) and 27 isolated from clinical samples from hospitals in Valencia, Spain, were tested for quinolone resistance by the disk diffusion method (4) (nalidixic acid, 30 μg; oxolinic acid, 2 μg; flumequine, 30 μg; ciprofloxacin, 5 μg; and levofloxacin, 5 μg). Among the studied isolates, 27 showed resistance to nalidixic acid and susceptibility to ciprofloxacin, 24 isolates were susceptible to both nalidixic acid and ciprofloxacin, and only 1, the A. veroni…
