Pronoms àtons i tònics en funció d’objecte a les estructures de doblament de clític del català antic

En aquest treball descriurem algunes de les estructures que integren pronoms tònics en funció d’objecte directe o d’objecte indirecte i examinarem les dades relatives a les configuracions de doblament de clític i de pronom tònic aïllat en català antic. L’apartat 2 presenta la identificació i descripció de les dades que estudiarem, les quals han estat extretes del Corpus del Català Antic constituït sota el projecte Vers una Sintaxi Històrica del Català. A l’apartat 3 s’examina la freqüència de les estructures esmentades i les dues seccions següents se centren en l’estudi de la forma ell en contrast amb a ell. A 6 s’ofereix una explicació general de la posició que ocupen els pronoms tònics dins la frase i a 7 es fa una comparació de les dades del català antic amb les del portuguès antic. Finalment, a 8 se citen els resultats d’aquest estudi preliminar

L'expressió de la conseqüència en català antic: les consecutives d’intensitat - manera

Tradicionalment els gramàtics hem agrupat sota el rètol d’oracions consecutives estructures molt diverses que tenen en comú el fet que la segona de les dues proposicions relacionades expressa la conseqüència del que es diu a la primera. Dins d’aquestes estructures s’han distingit dos grans grups. D’una banda, les anomenades consecutives paratàctiques o il·latives, on la relació lògica establerta entre les dues proposicions té caràcter asindètic o bé es codifica mitjançant un marcador discursiu i, de l’altra, les consecutives subordinades, on la proposició que expressa la conseqüència s’introdueix a través de nexos subordinants. En aquest article volem tractar l’evolució d’un tipus d’oracions consecutives subordinades, les anomenades consecutives d’intensitat-manera que il·lustrem amb els exemples de català medieval

Los nexos causales y finales en el Curial e Güelfa: descripción de una sincronía histórica

En este estudio se examinan las estructuras que expresan causa yfinalidad en el Curial e Güelfa. El estudio cuantitativo de los nexossimples y compuestos evidencia que el autor sigue un modelo retóricoacotado por la tradición de la scripta medieval catalana. A diferenciade los primeros textos, la lengua del Curial es una prosa trabada,alejada de la oralidad, en la que los nexos no suelen ser ambiguos y,por tanto, no se precisan inferencias pragmáticas para interpretar lasrelaciones lógicas existentes entre las proposiciones

Foco oracional y polaridad: en torno a una asimetría entre el español y el catalán

En aquest estudi s’examina la perifèria esquerra del català antic en comparació amb la del castellà antic, i es descriuen les diferències més rellevants

El prefijo a- en la formación de derivados verbales

Esta investigación se centra en el análisis de los verbos medievales que manifiestan alternancia en lo referente al prefijo a-. Aunque este tema se ha tratado en distintos estudios de carácter diacrónico —Malkiel (1941), García Medall (1988), Sánchez González de Herrero (1992), Sánchez-Prieto (1992)— los resultados alcanzados ponen de relieve la necesidad de profundizar en la descripción de las características de este tipo de formaciones cuyas implicaciones van más allá de la propia morfología

Procedural Meaning Explicatures in the Development of New Subordination Strategies in Romance

The sociocultural changes that led to the genesis of Romance languages widened the gap between oral and written patterns, which display different discoursive and linguistic devices. In early documents, discoursive implicatures connecting propositions were not generally codified, so that the reader should furnish the correctinterpretation according to his own perception of real facts; which can still be attested in current oral utterances. Once Romance languages had undergone several levelling processes which concluded in the first standardizations, implicatures became explicatures and were syntactically codified by means of univocal new complexconjunctions. As a consequence of the emergence of these new subordination strategies, a freer distribution of the information conveyed by the utterances is allowed. The success of complex structural patterns ran alongside of the genesis of new narrative genres and the generalization of a learned rhetoric. Both facts are a spontaneous effect of new approaches to the act of reading. Ancient texts were written to be read to a wide audience, whereas those printed by the end of the XV th century were conceived to be read quietly, in a low voice, by a private reader. The goal of this paper is twofold, since we will show that: a) The development of new complex conjunctions through the history of Romance languages accommodates to four structural patterns that range from parataxis tohypotaxis. b) This development is a reflex of the well known grammaticalization path from discourse to syntax that implies the codification of discoursive strategies (Givón 2 1979, Sperber and Wilson 1986, Carston 1988, Grice 1989, Bach 1994, Blackemore 2002, among others]

Ordre de mots i estructura informativa a la llengua de Francesc Eiximenis

En aquest estudi s’examina la llengua d’alguns textos de Francesc Eiximenis (concretament, el ‘Dotzè del Crestià’ i les cartes autògrafes publicades per Martí 2002) per tal d’aprofundir en la distribució de l’estructura informativa i el consegüent ordre de mots que utilitza l’autor. L’objectiu d’aquesta comunicació és aprofundir en els casos d’ avantposició del català antic que correspon a una estructura de focalització feble (no contrastiva)

Evolución de los derivados verbales con prefijo a- y en-: del latín al español clásico

Esta investigación en curso se centra en el análisis de los verbos con prefijo a- y en- en la historia del español. En la primera parte de esta investigación se ha elaborado un estado de la cuestión sobre la prefijación verbal con ad-, ab- e in- en latín. En la segunda parte se estudian las tendencias evolutivas de los derivados verbales en a- y en- en español medieval y clásico, a partir del análisis de los verbos de mayor frecuencia de uso que siguen estos esquemas en el corpus textual de Davies

Patrones en la evolución de los derivados verbales con prefijo a- y en-: el español clásico

Nos hemos propuesto hacer un estudio exhaustivo de la formación de los parasintéticos en: a—ar, a—ecer, en—ecer y en—ar desde una perspectiva histórica porque una primera aproximación a las formas parasintéticas puso de manifiesto que hay una estrecha relación entre estos modelos no sólo en la actualidad sino también desde la visión dinámica de la diacronía

Variación y periferia izquierda: la Anteposición de Foco Débil en español y en catalán

El objetivo de éste estudio es el análisis diacrónico y comparativo {español-catalán} de la Anteposición de Foco Débil (AFD) en las lenguas románicas medievales

Mesoclitic Romance futures and conditionals vs participle preposing

(INFINITIVE + CLITIC + AUX) is an evidential configuration in Old Spanish and Old Catalan, whereas (PARTICIPLE + CLITIC + AUX) is an instance of weak or unmarked focus fronting. The evidentiality of mesoclitic structures can be put forward on the bases of three main arguments: a) mesoclisis is not compulsory (i.e., whenever you have a clitic, you can either have mesoclisis or proclisis/enclisis); b) mesoclitic futures and conditionals areattested in interrogative sentences (with wh- elements); and c) they are not found in derived adverbial clauses (which is what you expect if they have an evidential value, since they bring about intervention effects corresponding to the derivational account of conditional and temporal sentences, for example - see Haegeman 2007 and ff.), and are related to high modal expressions (thus interfering with MoodPIrrealis)

A comparative study of the preventative effects exerted by two probiotics, Lactobacillus reuteri and Lactobacillus fermentum, in the trinitrobenzenesulfonic acid model of rat colitis

The intestinal anti-inflammatory effects of two probiotics isolated from breast milk, Lactobacillus reuteri and L. fermentum, were evaluated and compared in the trinitrobenzenesulfonic acid (TNBS) model of rat colitis. Colitis was induced in rats by intracolonic administration of 10 mg TNBS dissolved in 50% ethanol (0.25 ml). Either L. reuteri or L. fermentum was daily administered orally (5 x 10(8) colony-forming units suspended in 0.5 ml skimmed milk) to each group of rats (n 10) for 3 weeks, starting 2 weeks before colitis induction. Colonic damage was evaluated histologically and biochemically, and the colonic luminal contents were used for bacterial studies and for SCFA production. Both probiotics showed intestinal anti-inflammatory effects in this model of experimental colitis, as evidenced histologically and by a significant reduction of colonic myeloperoxidase activity (P<0.05). L. fermentum significantly counteracted the colonic glutathione depletion induced by the inflammatory process. In addition, both probiotics lowered colonic TNFalpha levels (P<0.01) and inducible NO synthase expression when compared with non-treated rats; however, the decrease in colonic cyclo-oxygenase-2 expression was only achieved with L.fermentum administration. Finally, the two probiotics induced the growth of Lactobacilli species in comparison with control colitic rats, but the production of SCFA in colonic contents was only increased when L. fermentum was given. In conclusion, L. fermentum can exert beneficial immunomodulatory properties in inflammatory bowel disease, being more effective than L. reuteri, a probiotic with reputed efficacy in promoting beneficial effects on human health.

Comparative evaluation of phenol and thimerosal as preservatives for a candidate vaccine against American cutaneous leishmaniasis

For decades thimerosal has been used as a preservative in the candidate vaccine for cutaneous leishmaniasis, which was developed by Mayrink et al. The use of thimerosal in humans has been banned due to its mercury content. This study addresses the standardization of phenol as a new candidate vaccine preservative. We have found that the proteolytic activity was abolished when the test was conducted using the candidate vaccine added to merthiolate (MtVac) as well as to phenol (PhVac). The Montenegro's skin test conversion rates induced by MtVac and by PhVac was 68.06% and 85.9%, respectively, and these values were statistically significant (p < 0.05). The proliferative response of peripheral mononuclear blood cells shows that the stimulation index of mice immunized with both candidate vaccines was higher than the one in control animals (p < 0.05). The ability of the candidate vaccines to induce protection in C57BL/10 mice against a challenge with infective Leishmania amazonensis promastigotes was tested and the mice immunized with PhVac developed smaller lesions than the mice immunized with MtVac. Electrophoresis of phenol-preserved antigen revealed a number of proteins, which were better preserved in PhVac. These results do in fact encourage the use of phenol for preserving the immunogenic and biochemical properties of the candidate vaccine for cutaneous leishmaniasis.

Imaging techniques and histology in the evaluation of liver fibrosis in hepatosplenic schistosomiasis mansoni in Brazil: a comparative study

Few publications have compared ultrasound (US) to histology in diagnosing schistosomiasis-induced liver fibrosis (LF); none has used magnetic resonance (MR). The aim of this study was to evaluate schistosomal LF using these three methods. Fourteen patients with hepatosplenic schistosomiasis admitted to hospital for surgical treatment of variceal bleeding were investigated. They were submitted to upper digestive endoscopy, US, MR and wedge liver biopsy. The World Health Organization protocol for US in schistosomiasis was used. Hepatic fibrosis was classified as absent, slight, moderate or intense. Histology and MR confirmed Symmers' fibrosis in all cases. US failed to detect it in one patient. Moderate agreement was found comparing US to MR; poor agreement was found when US or MR were compared to histology. Re-classifying LF as only slight or intense created moderate agreement between imaging techniques and histology. Histomorphometry did not separate slight from intense LF. Two patients with advanced hepatosplenic schistosomiasis presented slight LF. Our data suggest that the presence of the characteristic periportal fibrosis, diagnosed by US, MR or histology, associated with a sign of portal hypertension, defines the severity of the disease. We conclude that imaging techniques are reliable to define the presence of LF but fail in grading its intensity.
