[ES] Esta base de datos utiliza La Encuesta de actitudes hacia la estadística creada por Auzmendi (2009). Los datos se corresponden con los resultados de la encuesta pasados a alumnos de un único instituto de enseñanza secundaria en 3 niveles (4º de la ESO, 1BACH y 2BACH) a alumnos que han estado en contacto con conceptos estadísticos en la asignatura de matemáticas. La encuesta mide 5 dimensiones de las actitudes hacia la estadística. Motivación, confianza, ansiedad, utilidad y satisfacción

[EN] Social media platforms have had a significant impact on the public image of sports in recent years. Through the relational dynamics of the communication on these networks, many users have emerged whose opinions can exert a great deal of influence on public conversation online. This research aims to identify the influential Twitter users during the 2016 UCI Track Cycling World Championships using different variables which, in turn, represent different dimensions of influence (popularity, activity and authority). Mathematical variables of the social network analysis and variables provided by Twitter and Google are compared. As a result, no single variable assessed is sufficient to identify the different kinds of influential Twitter users. Having a certain type of account is not enough to make a user an influencer if they do not engage (actively or passively) in the conversation. Choosing some influencers or others will depend on the objectives pursued.

[EN] Microplastics and nanoplastics have arisen as contaminants of emerging concern due to the wide use of plastics, and the application of boron-doped diamond (BDD) electrodes for their removal is promising. In this study, we report the influence of BDD doping levels (500, 2500, and 10000 ppm B doping) on the electrooxidation of polystyrene nanoplastics (100 nm, 20 mg⋅L-1). Different current densities (50, 25, 12.5, and 5 mA⋅cm-2) have been applied to determine the best electrolysis conditions for each electrode type. In addition, hydroxyl radical (•OH), persulphate (S2O82-), and hydrogen peroxide (H2O2) reactive species have been determined to understand the influence of the species generated on the degradation of NPs. BDD500 electrode presents the fastest degradation of PS NPs at low current densities (12.5 and 5 mA⋅cm-2), BDD2500 at 25 mA⋅cm-2, and BDD10000 at 50 mA⋅cm-2. Among oxidative species determined, S2O82- is the one generated with the highest concentration and seems to command the degradation of PS NPs, since at 25, 12.5, and 5 mA⋅cm-2, the electrodes that produce more S2O82- degrade faster PS NPs. At 50 mA⋅cm-2, the differences between the different electrodes were minimal. The highest mineralization (as measured by non-purgeable organic carbon measurements) was obtained for BDD500 at 50, 25, and 12.5 mA⋅cm-2, and BDD2500 at 5 mA⋅cm-2., This research is part of the Spanish R +D +i contract TED2021-130905B-I00 funded by MCIN/AEI /10.13039/501100011033 and by the European Union NextGenerationEU/PRTR as well as the Red E3Tech Plus: Proyecto Redes de Investigación de la AEI Network E3Tech PLUS (RED2022-134552-T) project.

As aquaculture expands, replacing fishmeal with alternative proteins in low-trophic species such as Chelon labrosus is critical for sustainability. We evaluated growth performance over 153 days and nutrient digestibility of three isoproteic diets: a fully plant-based diet (V), a plant–animal blend without fishmeal (VA), and a control with 20% fishmeal (FM). Fish fed the V diet achieved the highest growth and feed efficiency, followed by FM, whereas VA resulted in poor performance and the lowest digestibility, likely linked to hemoglobin meal reducing feed acceptability. All diets significantly shifted intestinal microbial diversity from initial conditions, while dominant taxa remained largely stable. FM-fed fish showed a general decrease in bacterial abundance, including a marked reduction of Brevinema. The VA diet increased Vibrio and decreased Lactobacillus, suggesting compromised gut health. In contrast, V-fed fish displayed elevated Mycoplasma, a taxon previously associated with nutrient exchange and fiber digestion. Functional predictions indicated fewer metabolic alterations under plant-based diets, while FM induced the largest number of altered pathways. Overall, complete fishmeal replacement is feasible in C. labrosus, and diet–microbiome interactions are pivotal to optimizing sustainable mullet aquaculture., Ministerio de ciencia e investigación.

Multiple myeloma is a hematologic neoplasm caused by an uncontrolled clonal proliferation of neoplastic plasma cells (nPCs) in the bone marrow. The development and survival of this disease is tightly related to the bone marrow environment. Proliferation and viability of nPCs depend on their interaction with the stromal cells and the extracellular matrix components, which also influences the appearance of drug resistance. Recapitulating these interactions in an in vitro culture requires 3D environments that incorporate the biomolecules of interest. In this work, we studied the proliferation and viability of three multiple myeloma cell lines in a microgel consisting of biostable microspheres with fibronectin (FN) on their surfaces. We also showed that the interaction of the RPMI8226 cell line with FN induced cell arrest in the G0/G1 cell cycle phase. RPMI8226 cells developed a significant resistance to dexamethasone, which was reduced when they were treated with dexamethasone and bortezomib in combination., CIBER-BBN is an initiative funded by the VI National R&D&I Plan 2008–2011, Iniciativa Ingenio 2010, and Consolider Program.

Ethical slaughter practices for crustaceans remain poorly standardized, and their effects on product quality and consumer perception are insufficiently understood. This study evaluated four ice-slurry-based slaughter methods in Penaeus vannamei reared under intensive biofloc technology (BFT) and their impact on refrigerated shelf life. While BFT enhances farming sustainability, it may an increase in microbial load, potentially shaping post-mortem spoilage. Shrimp were subjected to cold thermal shock in seawater ice slurry (C-TS); a 5 min immersion in chilled seawater with 50 ppm sodium hypochlorite, followed by TS (5BTS); 3–4 h of intestinal clarification, followed by 1 min immersion in chilled seawater with 50 ppm sodium hypochlorite and subsequent TS (C1BTS); and TS, followed by UV-C exposure (TS-UV). Over 12 days at <4 ◦C refrigeration, culture-based microbiology (mesophilic bacteria, enterobacteria, psychrotrophs, pseudomonas, and specific spoilage organisms), total volatile nitrogen compounds (TVB-N), melanosis, and qualitative descriptive analysis were performed. Storage time showed typical spoilage patterns driven by psychrotrophic bacteria, TVB-N, and melanosis. Slaughter method influenced quality: C1BTS limited psychrotroph proliferation but accelerated melanosis, and TS-UV yielded the poorest performance. Notably, 5BTS delayed melanosis (~3 days), maintained sensory quality, and avoided excessive microbial growth, making it the most effective method. These findings provide practical guidance for additive-free shrimp processing and identify psychrotrophs as key spoilage indicators in BFT systems., This work was supported by I+D+i Research Project: “Pursuing the zero waste in Biofloc Technology to produce a sustainable and biosafe aquaculture product (ZeroFloc)” (PID2023-149570OB-I00).
