Determinación del periodo de retiro de enrofloxacina en cuyes (Cavia porcellus)

The aim of this study was to determine the period of withdrawal of enrofloxacin in guinea pigs (Cavia porcellus). In total, 51 guinea pigs (25 females and 26 males) of the Peru breed from a farm located in the district of Maranganí (Cusco, Peru) were used. For this, 10% enrofloxacin was administered orally at a rate of 10 mg/kg (0.1 ml/kg BW) every 24 hours for a period of 10 days. Immediately after the last administration of the antibiotic (hour 0), three guinea pigs were randomly selected and slaughtered every 2 hours until 32 hours after drug withdrawal, taking samples of the diaphragm muscle. The analysis and quantification of antibiotic residues in the muscle was performed using the commercial Max Signal® Enrofloxacin ELISA Kit. The maximum concentration of enrofloxacin (1425 ± 53.4 µg/kg) was determined 12 h after withdrawal, falling to 80.8 ± 6 µg/kg at 28 h, value below 100 µg/kg considered as the reference maximum residue limit. Under the conditions of this study, a withdrawal period of two days is suggested for guinea pigs treated with enrofloxacin.El objetivo del estudio fue determinar el periodo de retiro de enrofloxacina en cuyes (Cavia porcellus). Se utilizaron 51 cuyes (25 hembras y 26 machos) de la raza Perú de una granja ubicada en el distrito de Maranganí (Cusco, Perú). Para ello, se administró enrofloxacina al 10%, vía oral, a razón de 10 mg/kg (0.1 ml/kg PV) cada 24 horas por un periodo de 10 días. Inmediatamente después de la última administración del antibiótico (hora 0), tres cuyes fueron seleccionados en forma aleatoria y sacrificados cada dos horas hasta las 32 horas del retiro del fármaco, tomándose muestras del músculo diafragma. El análisis y cuantificación de los residuos del antibiótico en el diafragma se realizó empleando el kit comercial Max Signal® Enrofloxacin ELISA Kit. La concentración máxima de enrofloxacina (1425 ± 53.4 µg/kg) se determinó a las 12 horas del retiro, descendiendo hasta 80.8 ± 6 µg/kg a las 28 h, valor por debajo de 100 µg/kg considerado como límite máximo de referencia. Bajo las condiciones de este estudio, se sugiere un periodo de retiro de dos días para cuyes tratados con enrofloxacina

The T-REX project: Micromegas for rare event searches

The T-REX project aims at developing novel readout techniques for Time Projection Chambers for experiments searching for Rare Events. The Micromegas detectors are a good option, because of their good performance regarding low background levels, energy and time resolution, gain and stability of operation. In the present we will shortly refer to two particular cases, on one hand their performance in the CAST experiment and on the other the studies carried out within NEXT, a neutrinoless double-beta decay experiment

Production of seafood flavour formulations from enzymatic hydrolysates of fish by-products

© 2015 Published by Elsevier Ltd. Amino acid-rich extracts derived from fish by-products were utilised to generate flavour model systems with added glucose and/or fish oil. Combination of endo and exo peptidases resulted in the most marked increased in free amino acids, particularly for leucine, lysine and glutamic acid (48.3 ± 3.4 to 1423.4 ± 59.6, 43.3 ± 1.2 to 1485.4 ± 25.6 and 143.6 ± 21.7 to 980.9 ± 63.6 μg/g respectively).Main volatile products formed after heating the systems were 4-heptenal, 2,4-heptadienal, and some pyrazines. Increased concentrations of 1-octen-3-ol or 1-hepten-4-ol were also observed in the heated systems compared to the controls. All of these volatile compounds have been identified among the volatile profile of cooked seafood. Conversion of low value fish derived materials such as fish powder, into more valuable products such as flavour precursors and subsequently flavour compounds might be a commercially viable proposition for the fish industry

Inclusion of alternative marine by-products in aquafeeds with different levels of plant-based sources for on-growing gilthead sea bream (Sparus aurata, L.): effects on digestibility, amino acid retention, ammonia excretion and enzyme activity

[EN] The search for new sustainable aquafeeds for the species with greater economic importance, such as the gilthead sea bream in Europe, is one of the main challenges in the aquaculture sector. The present work tested fishmeal replacement by a mixture of plant meals at different levels, as well as the use of marine by-products with attractant properties and high-quality protein in high plant protein diets. In order to do that, effects on growth and biometric parameters, digestibility, amino acid retention, excreted ammonia and proteases and amylase activity were assessed, using six different diets: FM100 (100% of protein provided by fishmeal), FM50 (50% of replacement), FM25 (75% of replacement) and FM0 (100% of replacement), but also FM25+ (75% of replacement and 15% of squid and krill meal inclusion), and FM0+ (100% of replacement and 15% of squid and krill meal inclusion). In group FM0, a clear impact of dietary changes was observed on growth, survival and ammonia excretion. Amino acid retention in group FM0+ was also significantly affected, which can be explained by the limited content of certain amino acids in this diet. On the other hand, no significant differences were observed in most biometric parameters or in enzyme activity. In conclusion, complete fishmeal replacement can be achieved by using a mixture of plant-based sources, but supplementation with complementary marine ingredients can prevent detrimental effects on growth, survival, nutritional parameters and protein metabolism.This work was supported by the Vicerrectorat d'Investigacio, Innovacio i Transferencia of the Universitat Politecnica de Valencia, within the project Aquaculture feed without fishmeal (SP20120603).

Computational approaches to explainable artificial intelligence: Advances in theory, applications and trends

Deep Learning (DL), a groundbreaking branch of Machine Learning (ML), has emerged as a driving force in both theoretical and applied Artificial Intelligence (AI). DL algorithms, rooted in complex and non-linear artificial neural systems, excel at extracting high-level features from data. DL has demonstrated human-level performance in real-world tasks, including clinical diagnostics, and has unlocked solutions to previously intractable problems in virtual agent design, robotics, genomics, neuroimaging, computer vision, and industrial automation. In this paper, the most relevant advances from the last few years in Artificial Intelligence (AI) and several applications to neuroscience, neuroimaging, computer vision, and robotics are presented, reviewed and discussed. In this way, we summarize the state-of-the-art in AI methods, models and applications within a collection of works presented at the 9th International Conference on the Interplay between Natural and Artificial Computation (IWINAC). The works presented in this paper are excellent examples of new scientific discoveries made in laboratories that have successfully transitioned to real-life applications.MCIU - Nvidia(UMA18-FEDERJA-084

Long -term feeding with high plant protein based diets in gilthead seabream (Sparus aurata, L.) leads to changes in the inflammatory and immune related gene expression at intestinal level

[EN] Background: In order to ensure sustainability of aquaculture production of carnivourous fish species such as the gilthead seabream (Sparus aurata, L.), the impact of the inclusion of alternative protein sources to fishmeal, including plants, has been assessed. With the aim of evaluating long-term effects of vegetable diets on growth and intestinal status of the on-growing gilthead seabream (initial weight = 129 g), three experimental diets were tested: a strict plant protein-based diet (VM), a fishmeal based diet (FM) and a plant protein-based diet with 15% of marine ingredients (squid and krill meal) alternative to fishmeal (VM+). Intestines were sampled after 154 days. Besides studying growth parameters and survival, the gene expression related to inflammatory response, immune system, epithelia integrity and digestive process was analysed in the foregut and hindgut sections, as well as different histological parameters in the foregut. Results: There were no differences in growth performance (p = 0.2703) and feed utilization (p = 0.1536), although a greater fish mortality was recorded in the VM group (p = 0.0141). In addition, this group reported a lower expression in genes related to pro-inflammatory response, as Interleukine-1 beta (il1 beta, p = 0.0415), Interleukine-6 (il6, p = 0.0347) and cyclooxigenase-2 (cox2, p = 0.0014), immune-related genes as immunoglobulin M (igm, p = 0.0002) or bacterial defence genes as alkaline phosphatase (alp, p = 0.0069). In contrast, the VM+ group yielded similar survival rate to FM (p = 0.0141) and the gene expression patterns indicated a greater induction of the inflammatory and immune markers (il1 beta, cox2 and igm). However, major histological changes in gut were not detected. Conclusions: Using plants as the unique source of protein on a long term basis, replacing fishmeal in aqua feeds for gilthead seabream, may have been the reason of a decrease in the level of different pro-inflammatory mediators (il1 beta, il6 and cox2) and immune-related molecules (igm and alp), which reflects a possible lack of local immune response at the intestinal mucosa, explaining the higher mortality observed. Krill and squid meal inclusion in vegetable diets, even at low concentrations, provided an improvement in nutrition and survival parameters compared to strictly plant protein based diets as VM, maybe explained by the maintenance of an effective immune response throughout the assay.The research has been partially funded by Vicerrectorat d'Investigacio, Innovacio i Transferencia of the Universitat Politecnica de Valencia, which belongs to the project Aquaculture feed without fishmeal (SP20120603).

In this way, we summarize the state-of-the-art in AI methods, models and applications within a collection of works presented at the 9 International Conference on the Interplay between Natural and Artificial Computation (IWINAC). The works presented in this paper are excellent examples of new scientific discoveries made in laboratories that have successfully transitioned to real-life applications
