Cleaner fish escape salmon farms and hybridize with local wrasse populations
2018
The genetic impact of farmed fish escaping aquaculture is a highly debated issue. However, non-target species, such as cleaner fish used to remove sea lice from farmed fish, are rarely considered. Here, we report that wild corkwing wrasse (Symphodus melops), which are transported long distances to be used as cleaner fish in salmon farms, escape and hybridize with local populations. Recently, increasing numbers of corkwing wrasse have been reported in Flatanger in Norway, north of its described distribution range, an area heavily relying on the import of cleaner fish from Skagerrak. Using genetic markers identified with 2bRAD sequencing, we show that, although the Flatanger population largel…
The Fate of Bacteriophages in Recirculating Aquaculture Systems (RAS)—Towards Developing Phage Therapy for RAS
2019
Aquaculture production has increased tremendously during the last decades, and new techniques have been developed, e.g., recirculating aquaculture systems (RAS). In RAS, the majority of water volume is circulated via mechanical and biological filters and reused in the tanks. However, the prevention and treatment of diseases in these systems are challenging, as the pathogens spread throughout the system, and the addition of chemicals and antibiotics disrupts the microbiome of the biofilters. The increasing antibiotic resistance has made phage therapy a relevant alternative for antibiotics in food production. Indeed, as host-specific and self-replicating agent they might be optimal for target…
Las otras fallas: Imaginación metafórica como realidad de lo posible.
2009
Partiendo del análisis de dos obras concretas de construcciones falleras, confeccionadas en el propio taller del doctorando, y de la mano del estudio de determinadas concreciones estéticas de la imaginación metafórica, hemos pretendido esbozar el universo teórico-experimental que nos ha llevado a ser capaces de elaborar dichas obras en el espacio público de la calle, dentro del marco decidido de las otras fallas. La lucha contra las metáforas emanadas desde el Poder también puede hacerse creando otras realidades que desmonten esas virtualidad en que mayormente vivimos: o inventando pequeñas historias a medida de las personas, para contradecir la Historia que mienten l@s vencedor@s o mediant…
EPIdemiology of Surgery-Associated Acute Kidney Injury (EPIS-AKI): study protocol for a multicentre, observational trial

Effects of clopidogrel, prasugrel and ticagrelor on endothelial function, inflammatory and oxidative stress parameters and platelet function in patie…
2014
Introduction Particularly in the setting of acute coronary syndromes, the interplay between vascular and platelet function has been postulated to have direct clinical implications. The present trial is designed to test the effect of clopidogrel, prasugrel and ticagrelor on multiple parameters of vascular function, platelet aggregation, oxidative and inflammatory stress before and up to 4 weeks after coronary artery stenting. Methods and analysis The study is designed as a three-arm, parallel design, randomised, investigator-blinded study. Patients with unstable angina or non-ST elevation myocardial infarction undergoing coronary intervention with a drug-eluting stent will be randomised to r…
Enriched rearing environment and wild genetic background can enhance survival and disease resistance of salmonid fishes during parasite epidemics
2015
Summary 1. The importance and volume of aquaculture is increasing world-wide. Rearing practices play a key role in determining growth rate, survival and disease resistance in aquaculture fishes. Recent evidence suggests that in comparison with a standard stimulus-poor rearing environment, an enriched or variable rearing environment has significant positive effects on several traits underlying growth and well-being of fish. However, the effect of enriched rearing on one of the most important threats for aquaculture development, occurrence of parasitic infections, remains unknown. 2. We used surveillance data of experimental salmonid populations of wild and hatchery origin under semi-natural …
Effect of ferritin overexpression in tobacco on the structure of bacterial and pseudomonad communities associated with the roots
2006
The genetic structures of total bacterial and pseudomonad communities were characterized in rhizosphere soil and rhizoplane+root tissues of tobacco wild type and a ferritin overexpressor transgenic line (P6) by a cultivation-independent method using directly extracted DNA at the end of three consecutive plant cultures. The structure of total bacterial communities was characterized by automated ribosomal intergenic spacer analysis (A-RISA), and that of pseudomonad communities was characterized by PCR-restriction fragment length polymorphism (PCR-RFLP) from DNA amplified with specific primers. The structure of total bacterial communities was significantly modified in the rhizosphere soil by t…
Volatile components of dry-cured ham
1991
The volatile components of dry-cured ham were isolated by vacuum distillation and analyzed by gas chromatography-mass spectrometry. The structures of 76 molecules were identified by mass spectrometry, cochromatography, or measured Kovats indices. The compounds identified may come from the catabolism of the main constituent parts of the meat (glucids, lipids and protids) during the curing of the hams, from the pig feed, or from technological processes. The volatile compounds extracted from 50 g of ham according to the technique described correspond to a chromatographical surface equivalent to 0.12 mg of the dodecane internal standard, or approximately 2.4 ppm of the weight of the sample. Fla…
Problématiques de la nutrition en ophtalmologie – application à la dégénérescence maculaire liée à l’âge
2014
Nutrition in ophthalmology – clinical application to age-related macular degeneration «Let food be your medicine.» This contribution from Hippocrates is still timely addressed, especially in the field of ophthalmology. Observational epidemiology reports close associations between food habits and the risk or prevention of several ocular pathologies such as cataract or Age-related Macular Degeneration (AMD). Anti-oxidant vitamins, minerals and lipids are the nutrients that have been the most widely studied. Interventional epidemiology and experimental works partially corroborated these findings. Unexpectedly, the benefit of long chain omega 3 polyunsaturated fatty acids in the prevention of l…
COVID-19 Infection Process in Italy and Spain: Are the Data Talking?
2020
Background: COVID-19 has spread successfully worldwide in a matter of weeks. After the example of China, all the affected countries are taking hard-confinement measures to control the infection and to gain some time to diminish the big amount of cases that arrive to hospital. Although the measures in China reduced the percentages of new cases, this is not seen in other countries that have taken similar measures, such as Italy and Spain. Now we are in the middle of a battle trying to prevent the healthcare system from collapsing while it effectively responds to the needs of patients who are infected and require hospitalization. Methods: Using China as a mirror of what could happen in our cou…
