Taxonomic complexity in the halophyte Limonium vulgare and related taxa (Plumbaginaceae): insights from analysis of morphological, reproductive and k…
2014
Part of a special issue on halophytes and saline adaptations Background and Aims Limonium is awell-known example of a group of plants that is taxonomically complex due to certain biological characteristics that hamper species’ delineation. The closely related polyploid species Limonium vulgare Mill., L. humile Mill. and L. narbonense Mill. are defined species and can be used for studying patterns of morphological and reproductive variation. The first two taxa are usually found in Atlantic Europe and the third in the Mediterranean region, but a numberof intermediate morphological formsmay be present alongside typical examples of these species. This study attempts to elucidate morphological, …
Influence of the early bacterial biofilms developed on vats made with seven wood types on PDO Vastedda della valle del Belìce cheese characteristics
2019
Early vat bacterial biofilms developed spontaneously through contact with whey have been characterized on seven wood types (Castanea sativa Miller, Cedrus libani, A. Rich., Prunus avium L., Fraxinus ornus L., Juglans regia L., Pinus nigra J.F. Arnold and Populus nigra L.). The present study aimed to evaluate the influence of these biofilms on the microbiological, chemical, physical and sensory characteristics of PDO Vastedda della valle del Belìce (VdB) cheese, processed traditionally from raw ewe's milk using wooden tools. To this purpose, the experimental cheeses after 15 d of refrigerated storage were examined. Lactic acid bacteria (LAB) populations dominated the microbial community of a…
Barack Obama's South Carolina speech
2010
Abstract In this paper, I shall analyze US Presidential Barack Obama's South Carolina victory speech from the perspective of pragmemes. In particular, I shall explore the idea that this speech is constituted by many voices (in other words, it displays polyphony, to use an idea due to Bakhtin, 1981 , Bakhtin, 1986 ) and that the audience is part of this speech event, adding and contributing to its text in a collaborative way (in particular, in constructing meaning). As many are aware (including the journalists who report day by day on Barack Obama's achievements), Obama uses the technique of ‘personification’ 1 ( The Economist , December 13th, 2007). When he voices an idea, he does not just …
Fixing meaning
2012
This contribution looks into a speech by Russian President Vladimir Putin after the terrorist attack against a high school in the Northern Caucasian town Beslan in September 2004, widely seen as marking the end of the liberal hegemony in the Russia of the post-soviet period. However, a closer look reveals the many possible readings that are made of the speech. According to the reactions found in a corpus of press articles, the speech activates both “internationalist” and “sovereignist” readings in media discourse. By pointing out the polyphonic organization of discourse, I make the case for a productive exchange between the French tradition of discourse analysis, interactionism and critical…
Louise Doutreligne’s Signé Pombo: a French dramatic transposition of the Manuel Vázquez Montalbán’s "Autobiografía del general Franco"
2014
Signé Pombo, también titulada Dans la peau de Franco es una creación dramática francesa de Louise Doutreligne libremente inspirada, como consta en la cubierta de la edición de Moi, Franco, título con el que se ha traducido en francés la Autobiografía imaginaria del General Franco de Manuel Vázquez Montalbán. En este artículo se estudian las transformaciones creativas a que ha sido sometida el relato de Vázquez Montalbán, atendiendo principalmente a las modificaciones cuantitativas, la reordenación de la materia y el paso de la polifonía narrativa a una polifonía escénica, planteándose si la autora ha procedido a cambios pensando en una recepción lectora o teatral francesa. Signé Pombo¸ inti…
Extracts deriving from olive mill waste water and their effects on the liver of the goldfish Carassius auratus fed with hypercholesterolemic diet
2014
The present research aims to evaluate the beneficial effects of polyphenols derived from waste water from a olive mill, obtained by non-plastic molecular imprinting device, in a hypercholesterolemic diet on Carassius auratus, commonly known as goldfish that was selected as experimental model. The study was conducted with morphological and histochemical analyses and also the data were supported by immunohistochemical analysis. Results show the beneficial activity of polyphenols with a reduction of the damage in the steatotic group, confirming that they may be suggested in the treatment of diseases by lipid accumulation, and used as any addition in feed for farmed fish, in order to improve th…
Hypoxia-inducible factor 1 alpha expression increases during colorectal carcinogenesis and tumor progression
2008
Abstract Background Hypoxia-inducible factor 1 alpha (HIF-1α) is involved in processes promoting carcinogenesis of many tumors. However, its role in the development of colorectal cancer is unknown. To investigate the significance of HIF-1α during colorectal carcinogenesis and progression we examined its expression in precursor lesions constituting the conventional and serrated pathways, as well as in non-metastatic and metastatic adenocarcinomas. Methods Immunohistochemistry and Western blot is used to analyse HIF-1α expression in normal colonic mucosa, hyperplastic polyps (HPP), sessile serrated adenomas (SSA), low-grade (TA-LGD) and high-grade (TA-HGD) traditional adenomas as well as in n…
Study of Potential Anti-Inflammatory Effects of Red Wine Extract and Resveratrol through a Modulation of Interleukin-1-Beta in Macrophages
2018
Inflammation has been described as an initiator event of major diseases with significant impacts in terms of public health including in cardiovascular disease, autoimmune disorders, eye diseases, age-related diseases, and the occurrence of cancers. A preventive action to reduce the key processes leading to inflammation could be an advantageous approach to reducing these associated pathologies. Many studies have reported the value of polyphenols such as resveratrol in counteracting pro-inflammatory cytokines. We have previously shown the potential of red wine extract (RWE) and the value of its qualitative and quantitative polyphenolic composition to prevent the carcinogenesis process. In thi…
Protective effect of grape extract phospholipid vesicles against oxidative stress skin damages
2016
Abstract Grape extract rich in polyphenols (∼129 ± 32 mg of gallic acid equivalents per g of dry extract) was obtained from the pomaces of Cannonau grapes by homogenization in an ethanol/water mixture. The efficacy of ultrasounds in speeding up the extraction kinetics of polyphenols was demonstrated. The extract was incorporated in liposomes and PEVs (penetration enhancer containing vesicles) with Labrasol ® or Labrasol ® /ethanol. All the vesicles were spherical and predominantly unilamellar: liposomes were large (∼927 nm) and polydispersed (PI ∼0.56), while PEVs were small (∼140 nm) and fairly homogeneous (PI ∼0.3). Moreover, PEVs were able to incorporate a high amount of the extract (∼98…
Dictionaries and translation of contemporary novels
2014
Par leur caractère polyphonique, de nombreux romans contemporains posent des problèmes lexicaux au traducteur en mélangeant lexique standard, argot et termes techniques. La question qui se pose est alors de savoir si les dictionnaires peuvent être utiles au praticien. Nous verrons que pour des raisons théoriques et pratiques, l’aide qu’ils apportent est limitée, un dictionnaire réellement utile devrait changer ses présupposés conceptuels, donc devenir un dictionnaire culturel et adopter une forme électronique. Lexical problems do arise in many contemporary novels because of their polyphonic nature, mixing standard words, slang and technical terms. We must then ask ourselves if dictionaries …
