L'EXPRESSION DE LA CONCESSION À TRAVERS DES LOCUTIONS "QUELQUE...QUE" ET "QUEL QUE" ET LEURS ÉQUIVALENTS EN ESPAGNOL
[EN] We intend to pay special attention to a particular diffi culty for French Language students in level
B2/C1, whether their native language is Spanish, French or any other else. That is distinguishing “quelque” in
form and function: fi rstly, between indefi nite determiner and adverb; secondly, between concessive constructions
“quelque…que” and “quel que”. These expressions manifest a phonetic similarity that must be solved
when writing by means of a grammatical analysis and by a contrastive analysis with the Spanish equivalent
construction through translation or “thème grammatical”. Doing so will help us to adapt our teaching and
face the special needs of our students within the European Higher Education Area framework.[FR] Parmi ces subtilités de la langue française nous choisissons de nous arrêter sur un point qui pose des problèmes aux étudiants hispanophones, francophones ou d'autres origines linguistiques, qui possèdent un niveau B2/C1 en français. Il s'agit de distinguer sous une même forme, quelque, différentes fonctions : d'abord entre le déterminant indéfi ni et l'adverbe puis l'utilisation de cet élément dans les tours concessifs quelque... que et quel que. Ces formules présentent la plupart du temps un syncrétisme phonique qui doit être élucidé à l'écrit aussi bien au niveau de l'analyse grammaticale qu'à travers une analyse constrastive avec la construction espagnole grâce à la traduction ou thème grammatical. Cela nous permet d'adapter notre enseignement et de faire face aux besoins éducatifs spéciaux de nos apprenants dans le cadre du EEES.Molina Romero, MC. (2010).

Interference of non-specific detergents in microbial inhibitor test results for screening antibiotics in goat s milk
[EN] Cleaning and disinfection of dairy equipment is essential to ensure the hygienic quality of milk.
Occasionally, some farmers use washing-up liquids and disinfectants for home use, especially when
cleaning procedures are carried out manually. Residues of detergents and disinfectants in milk may
interfere with the response of microbial inhibitor tests used for screening antibiotics in milk. Therefore,
the aim of this study was to evaluate the interference of non-specific detergents in screening tests
(BRT MRL; Delvotest SP-NT MCS; Eclipse 100) for goat s milk. Twelve replicates of eight concentrations
of five washing-up liquids (0 1%) and one disinfectant (0 1%) were analysed. The results showed that
the presence of washing-up liquids at concentrations of ≥1 ml/l leads to positive results in microbial
tests. In particular, the product containing sodium laureth sulphate and ethanol produced the largest
number of positive outcomes. The presence of disinfectant based on sodium hypochlorite did not
affect the test response. The detection capabilities of microbial inhibitor tests for penicillins were also
studied in milk with and without cleaning products, calculating the dose response curve with eight
concentrations of amoxicillin, ampicillin, benzylpenicillin and cloxacillin, respectively. The detection
limits of the screening tests for penicillins were not modified substantially by the cleaning product
based on sodium laureth sulphate and ethanol. Residues of cleaning agents in milk can be avoided
when specific detergents and disinfectants for milking equipment are used and good cleaning
practices are applied.This work forms part of the Project AGL 2009-11524 financed by the Ministry of Science and Innovation (Madrid, Spain).Romero Rueda, T.; Beltrán Martínez, MC.; Althaus, RL.; Molina Pons, MP.

Drug residues in goat s milk after to the prophylactic use of antibiotics in intravaginal sponges for estrus synchronization
[EN] The aim of this study was to determine whether the prophylactic use of antibiotics in intravaginal sponges used for estrus synchronization in goats may result in the presence of inhibitors in milk and, therefore, of positive results by microbial screening tests. Ninetyeight Murciano-Granadina goats were used, divided into 7 groups of 14 animals. Intravaginal sponges were placed in 6 groups using 2 concentrations of 3 different antibiotics: doxycycline, oxytetracycline, and sulfathiazole-
framycetin. The sponges of the control group were placed without antibiotics. Milk samples were collected daily until 7 d posttreatment and analyzed using 3 microbial tests. Positive samples were retested by specific receptor-binding assays to confirm the positive results. Vaginal status was evaluated by visual assessment of the external aspect of the sponges after removal. The microbial test response was not affected by either day posttreatment or dose of antibiotic used, except for
oxytetracycline at the higher concentration. Moreover, no positive results were obtained using receptor-binding assays, suggesting that residues, if present in milk, did not exceed the regulatory (safety) levels established for these drugs. The occurrence of soiled sponges was higher in the control group. With respect to the dose of antibiotics used, no significant differences were found
for the lower dose administered. However, a significant increase in the percentage of clean sponges was observed for the higher dose of doxycycline. We conclude that the prophylactic use of low doses of doxycycline, oxytetracycline, or sulfathiazole in intravaginal sponges used for synchronization of estrus helps to reduce clinical vaginitis in dairy goats and does not seem to be the cause of positive results in microbial inhibitor tests used to detect antibiotics in goat milk.This work is part of the AGL-2009-11524 Project funded by the Spanish Ministry of Science and Innovation (Madrid, Spain).

The importance of Mycobacterium tuberculosis strains with disputed rpoB mutations remains to be defined. This study aimed to assess the frequency and types of rpoB mutations in M. tuberculosis isolates from Cubal, Angola, a country with a high incidence of tuberculosis.
Methods
All isolates included (n = 308) were analyzed using phenotypic drug susceptibility testing and GenoType MTBDRplus assay. DNA sequencing of the rpoB gene and determination of rifampicin MIC by macrodilution method were additionally performed on isolates yielding discordant results (n = 12) and those in which the mutation detected was not characterized (n = 8).
Results
In total, 85.1% (74/87) of rifampicin-resistant strains had undisputed rpoB mutations -S450L (49), D435V (15), H445D (3), H445Y (2), Q432ins (1), L449M plus S450F (1), S450F (1), S450W (1) and S450Y (1)-; 10.3% (9/87) had disputed rpoB mutations—L430P plus S493L (1), N437del (1), H445L (3), D435Y (2), L452P (2)-, 2.3% (2.3%) showed no rpoB mutations and 2.3% (2/87) showed heteroresistance—D435Y plus L452P and L430P plus S493L-.
Conclusion
Disputed rpoB mutations were common, occurring in 10.3% of rifampicin resistant isolates. Current phenotyping techniques may be unable to detect this resistance pattern. To increase their sensitivity, a lower concentration of RIF could be used in these tests or alternatively, rpoB mutations could be screened and characterized in all M. tuberculosis strains.This work was supported by Probitas Foundation.

re-habitar El Carmen : Un proyecto sobre patrimonio contemporáneo
El proyecto _re-HABITAR suponía para el propio proceder de la institución un avance más allá del reconocimiento, registro, inventario o protección patrimonial de la arquitectura del siglo XX y del Movimiento Moderno para posicionarse en la acción preventiva y conservativa de ese legado contemporáneo. Para ello, la praxis patrimonial se aferraba a un modelo: el de la vivienda social en España en la segunda mitad del siglo XX; a un caso concreto: el de la barriada de Nuestra Señora del Carmen (Recasens Méndez-Queipo de Llano, 1958); y a un requisito fundamental: analizar un objeto vivo y en uso, aún con la presencia de quienes lo vivieron y usaron desde su origen

Dietary α‐Linolenic Acid, Marine ω‐3 Fatty Acids, and Mortality in a Population With High Fish Consumption: Findings From the PREvención con DIeta MEDiterránea (PREDIMED) Study
Background: Epidemiological evidence suggests a cardioprotective role of α‐linolenic acid (ALA), a plant‐derived ω‐3 fatty acid. It is unclear whether ALA is beneficial in a background of high marine ω‐3 fatty acids (long‐chain n‐3 polyunsaturated fatty acids) intake. In persons at high cardiovascular risk from Spain, a country in which fish consumption is customarily high, we investigated whether meeting the International Society for the Study of Fatty Acids and Lipids recommendation for dietary ALA (0.7% of total energy) at baseline was related to all‐cause and cardiovascular disease mortality. We also examined the effect of meeting the society's recommendation for long‐chain n‐3 polyunsaturated fatty acids (≥500 mg/day). Methods and Results: We longitudinally evaluated 7202 participants in the PREvención con DIeta MEDiterránea (PREDIMED) trial. Multivariable‐adjusted Cox regression models were fitted to estimate hazard ratios. ALA intake correlated to walnut consumption (r=0.94). During a 5.9‐y follow‐up, 431 deaths occurred (104 cardiovascular disease, 55 coronary heart disease, 32 sudden cardiac death, 25 stroke). The hazard ratios for meeting ALA recommendation (n=1615, 22.4%) were 0.72 (95% CI 0.56–0.92) for all‐cause mortality and 0.95 (95% CI 0.58–1.57) for fatal cardiovascular disease. The hazard ratios for meeting the recommendation for long‐chain n‐3 polyunsaturated fatty acids (n=5452, 75.7%) were 0.84 (95% CI 0.67–1.05) for all‐cause mortality, 0.61 (95% CI 0.39–0.96) for fatal cardiovascular disease, 0.54 (95% CI 0.29–0.99) for fatal coronary heart disease, and 0.49 (95% CI 0.22–1.01) for sudden cardiac death. The highest reduction in all‐cause mortality occurred in participants meeting both recommendations (hazard ratio 0.63 [95% CI 0.45–0.87]). Conclusions: In participants without prior cardiovascular disease and high fish consumption, dietary ALA, supplied mainly by walnuts and olive oil, relates inversely to all‐cause mortality, whereas protection from cardiac mortality is limited to fish‐derived long‐chain n‐3 polyunsaturated fatty acids.

Effect in vitro of antiparasitic drugs on microbial inhibitor test responses for screening antibiotic residues in goat's milk
Microbial inhibitor tests are widely used to screen antibiotic residues in milk; however, these tests are nonspecific and may be affected by various substances capable of inhibiting the growth of the test microorganism. The objective of this study was to determine the effect of antiparasitic drugs in goat s milk on the microbial inhibitor test response. Raw antibiotic-free milk from Murciano-Granadina goats was supplemented with eight concentrations of seven antiparasitic substances (albendazole, 10 to 170
mg/kg; closantel, 1 to 140 mg/kg; diclazuril, 8 to 45 mg/kg; febendazole, 10 to 140 mg/kg; levamisole, 40 to 440 mg/kg; diazinon, 8 to 45 mg/kg; and ivermectin, 40 to 200 mg/kg). Twelve replicates for each concentration were analyzed with three microbial inhibitor tests: BRT MRL, Delvotest SP-NT MSC, and Eclipse 100. The results were interpreted visually (negative or positive). Using a logistic regression model, the concentrations of the antiparasitic drugs producing 5% (IC5), 10% (IC10), and 50% (IC50) positive results were determined. In general, the Eclipse 100 test was less sensitive to the effect of antiparasitic substances; the inhibitory concentrations of almost all the drugs assayed were higher than those for other tests. Conversely, the BRT MRL test was most affected, with high levels of interference at lower antiparasitic drug concentrations. Closantel and diazinon interfered with all microbial tests at lower concentrations than did other drugs (IC5 ~ 1 to 26 and 12 to 20 mg/kg,
respectively), and higher concentrations of levamisole and diclazuril (IC5 ~ 30 to 240 and 50 to 117 mg/kg, respectively) were required to produce 5% positive results. These findings indicate that microbial inhibitor tests can be affected by elevated concentrations of antiparasitic drugs in goat s milk.This work is part of project AGL-2009-11524 funded by the Ministry of Science and Innovation (Madrid, Spain) and the Generalitat Valenciana (ACOMOP/2012/164, Valencia, Spain).
