La interacción oral como proceso significativo en el aprendizaje/ adquisición de la Lengua Extranjera
2007
L’articolo prende in esame il ruolo dell’interazione orale in seno ai complessi meccanismi che interessano il processo di apprendimento/acquisizione di una lingua straniera e, in concreto, dello spagnolo. L’importanza dell’elemento interattivo è visto qui in una prospettiva funzionale non solo all’acquisizione di abilità e competenze linguistiche tout court, bensì in senso più ampio in relazione alla capacità del discente di appropriarsi di meccanismi e hábitos che gli permettano di interagire nelle diverse situazioni comunicative in modo non conflittuale nella lingua meta. Tale conflittualità con i propri interlocutori è da rintracciarsi nella mancata cooperazione negli aspetti conversazio…
Progetti di lessicografia onomastica dell’Atlante Linguistico della Sicilia
2022
L’Atlante Linguistico della Sicilia ha adottato, già una decina di anni fa, lo strumento del dizionario-atlante. Quando si è cominciato ad indagare il ricco universo onomastico, se ne è valutata la spendibilità anche su tre diversi corpora orali: uno relativo alle forme popolari del patrimonio toponomastico (DAToS, Dizionario-atlante toponomastico della Sicilia), uno riguardante l’inventario plurale dei soprannomi etnici (DASES, Dizionario-atlante dei soprannomi etnici in Sicilia), l’ultimo afferente al patrimonio antroponomastico popolare, individuale e familiare (DASS, Dizionario-atlante dei soprannomi di/in Sicilia). Il contributo fornisce lo stato dell’arte dei tre progetti e ne descriv…
Granular cell tumor: report of 8 intraoral cases.
2006
El Tumor de células granulares es una neoplasia de origen controvertido que puede aparecer en múltiples localizaciones corporales, incluyendo la región orofacial. El comportamiento de este infrecuente tumor es benigno en la mayor parte de los casos, aunque en ocasiones puede presentar agresividad local e incluso malignidad con afectación a distancia. Su etiología es actualmente solo parcialmente conocida y ha generado controversia desde sus primeras descripciones teorizando sobre un origen muscular, conectivo, etc o neural. En este trabajo se presentan 8 casos clínicos con localización intraoral, correspondientes a 5 mujeres y 3 hombres, con una edad media de 36,1 años y en los que la local…
Improving Dissolution Behavior and Oral Absorption of Drugs with pH-Dependent Solubility Using pH Modifiers: A Physiologically Realistic Mass Transpo…
2021
Orally dosed drugs must dissolve in the gastrointestinal (GI) tract before being absorbed through the epithelial cell membrane. In vivo drug dissolution depends on the GI tract's physiological conditions such as pH, residence time, luminal buffers, intestinal motility, and transit and drug properties under fed and fasting conditions (Paixao, P. et al. Mol. Pharm. 2018 and Bermejo, et al. M. Mol. Pharm. 2018). The dissolution of an ionizable drug may benefit from manipulating in vivo variables such as the environmental pH using pH-modifying agents incorporated into the dosage form. A successful example is the use of such agents for dissolution enhancement of BCS class IIb (high-permeability,…
Viscosity-mediated negative food effect on oral absorption of poorly-permeable drugs with an absorption window in the proximal intestine: In vitro ex…
2014
Concomitant food intake can diminish oral absorption of drugs with limited permeability and an absorption window in the proximal intestine, due to viscosity-mediated decrease in dosage form disintegration time and drug dissolution rate. Three poorly-permeable drugs (atenolol, metformin hydrochloride, and furosemide) exhibiting negative food effect, and one highly-soluble and highly-permeable (metoprolol tartrate), serving as a negative control, were selected for the study. In vitro and in silico tools were used to evaluate the influence of media viscosity on drug bioperformance under fasted and fed conditions. The obtained results demonstrated that increased medium viscosity in the presence…
Micellar liquid chromatography for prediction of drug transport.
2000
Abstract The vast majority of well absorbed drugs are transported passively across the cell membranes. Physicochemical descriptors of drug molecules that are believed to influence transcellular transport are routinely used to predict drug absorption by means of complex mathematical models. In this paper, a new in vitro method, based on the retention data in micellar liquid chromatography (MLC), is validated for the prediction of passive drug absorption. The retention of a heterogeneous drugs set in MLC using Brij 35 as surfactant in the mobile phase is compared with the retention data reported in literature obtained in red cell membrane lipid liposomes, human red cell membranes vesicles (ve…
Effects of temperature on gastric evacuation rate and absorption and transport of dietary lipids in sea bass (Dicentrarchus labrax, L.)
1993
Abstract 1. 1. Gastric evacuation rate and lipid absorption and transport were studied in sea bass reared at 25°, 20° and 15°C. 2. 2. An increase in gastric evacuation and a reduction in lipid absorption were observed at the higher temperature. 3. 3. Lowering temperature (15°C), led to a decrease in the rate of gastric emptying, with a prolonged lipid absorption. 4. 4. Relationships between lipid absorption and gastric evacuation are discussed.
O2.1. FIRST EPISODE PSYCHOSIS PATIENTS ACROSS EUROPE DIFFER IN INTELLECTUAL QUOTIENT (IQ) AND EXPOSURE TO ENVIRONMENTAL HAZARDS
2018
Abstract Background Children who later develop Schizophrenia on average are more likely to present with lower IQ; this has been considered evidence for the neurodevelopmental theory of schizophrenia. Though, recent studies have shown that first episode psychosis patients with a history of cannabis use have significantly higher premorbid and current IQ compared to those who never used it. This suggests that abnormal early neurodevelopment does not explain the aetiology of all cases of Schizophrenia, leaving space to environmental hazards. The present study aims to: investigate differences in IQ, as a marker of neurodevelopment, and in exposure to environmental risk factors in a large sample …

Relation between health literacy, self-care and adherence to treatment with oral anticoagulants in adults: a narrative systematic review
2018
Background Oral anticoagulants (OAC) are widely used in patients with cardiovascular diseases. However, for optimal OAC self-care patients must have skills, among which health literacy (HL) is highlighted. We aimed to describe the relation between HL and self-care in cardiovascular patients on OAC treatment. Methods Electronic searches were carried out in the PubMed, Scopus, Embase, CINAHL, Web of Science, Cochrane Library, SciELO, IME-Biomedicina, CUIDEN Plus and LILACS databases, limited to Spanish and English language and between January 2000–December 2016. Papers reported on adults older than 18 years, taking OAC by themselves for at least three months. PRISMA guidelines were used for p…
