Análisis de las propiedades psicométricas de la versión española del cuestionario de clima en el deporte

The psychometric properties of the Spanish version of the Sport Climate Questionnaire (S-SCQ) (SDT, Sport Climate Questionnaire, n.d.) were determined from a sample of 301 Spanish high-level competitive athletes (171 men and 130 women) from the Community of Valencia. The S-SCQ assesses athletes' perceptions of coach-provided autonomy support. The assumed uni-dimensional structure of both the long and short versions of the instrument was supported. Both versions also exhibited high reliability (internal consistency). Support for the convergent validity of the scale(s) was also obtained as the measure of coach autonomy support significantly related to the different types of motivation regulations (as assessed via the Sport Motivation Scale; Pelletier et al., 1995), in accordance with theoretical predictions

The perspective of customers and repair companies

Publisher Copyright: © 2023 The Author(s)Using repair services instead of new purchases creates local added value and contributes to a circular economy. The main aim of this research was to characterize repair service convenience for customers and to investigate ways to increase convenience to make repairs more attractive for customers, as the construct service convenience has neither been used nor adapted to a repair context until now. For this purpose, focus group interviews with potential customers of repair companies and interactive workshops with repair companies were conducted in the region of Styria (Austria). Findings state that a variety of factors like lack of information regarding repair services and product repairability, inconvenient store hours, or long waits reduce repair service convenience. However, due to skilled labor shortage, long delivery times of spare parts, or lacking financial resources for advertisements, repair companies can only partially improve convenience. Considering that, interventions from different actors, for example, the local government are needed as they can increase convenience by organizing awareness/information events, repair networks, or central repair-points. Hence, this study highlights once more the necessity to collaborate with different stakeholders (including customers, repair companies, local initiatives, and governments) to successfully transform the linear economy to a circular economy.publishersversionpublishe

Examination of the psychometric properties of the spanish version of the Approach to Coping in Sport questionaire

This study examined the psychometric properties of a Spanish version of the Approach to Coping in Sport Questionnaire and potential cultural differences in coping strategies between Spanish, Korean and US athletes. A total of 190 Spanish athletes (Male, N =152, Female, N = 38, M age = 21.2 + 4.4 years) from various sports participated in the study. After specifying the frequency of the experience of psychological difficulties during competition, the athletes indicated how often they used each of the coping strategies targeted in the ACSQ-Spanish and they also completed the Athletic Coping Skills Inventory-28. The results of CFA provided support for the factorial validity of the ACSQ-Spanish and preliminary evidence regarding concurrent and convergent validity was garnered. Differences in the use of different coping strategies between the Spanish, Korean, and US athlete groups emerged.En este estudio se analizan las propiedades psicométricas de la versión Española del ACSP (Approach to Coping in Sport Questionnaire) y las potenciales diferencias culturales existentes entre los deportistas españoles, coreanos y americanos en las estrategias de afrontamiento. 190 deportistas españoles (Hombres, N = 152; Mujeres, N = 38; M edad = 21.2 + 4.4 años) de varios deportes participaron en este estudio. Después de especificar la frecuencia de dificultades psicológicas que tenían durante la competición, los deportistas indicaban con que frecuencia utilizaban cada una de las estrategias de afrontamiento que figuraban en ACSP-Español y también rellenaron el Athletic Coping Skills Inventory 28.

Coinoculation of soybean plants with Bradyrhizobium japonicum and Trichoderma harzianum: Coexistence of both microbes and relief of nitrate inhibition of nodulation

Coinoculation of plants with mixtures of beneficial microbes sometimes produces synergistic effects. In this study, the effect of soybean coinoculation with the N2-fixing Bradyrhizobium japonicum E109 and the biocontrol fungus Trichoderma harzianum Th5cc was analyzed. Nodulation by E109 was not hampered by Th5cc, which antagonized five out of seven soybean pathogens tested. Furthermore, Th5cc relieved nitrate-inhibition of nodulation, enabling the formation of nodules containing infected cells with bacteroids in the presence of the otherwise inhibitory 10 mM KNO3. Th5cc released micromolar amounts of auxin, and addition of 11 mM indoleacetic acid to soybean plants inoculated with E109 in the absence of Th5cc also induced nodulation in the presence of 10 mM KNO3. Thus, Th5cc may release auxins into the soybean rhizosphere, which hormones might participate in overcoming the nitrate-inhibition of nodulation. Our results suggest that soybean plants coinoculated with these microorganisms might benefit from biocontrol while contributing to soil-nitrogen preservation.Fil: Iturralde, Esteban Tomás.

Genomic Analysis of Molecular Bacterial Mechanisms of Resistance to Phage Infection

[Abstract] To optimize phage therapy, we need to understand how bacteria evolve against phage attacks. One of the main problems of phage therapy is the appearance of bacterial resistance variants. The use of genomics to track antimicrobial resistance is increasingly developed and used in clinical laboratories. For that reason, it is important to consider, in an emerging future with phage therapy, to detect and avoid phage-resistant strains that can be overcome by the analysis of metadata provided by whole-genome sequencing. Here, we identified genes associated with phage resistance in 18 Acinetobacter baumannii clinical strains belonging to the ST-2 clonal complex during a decade (Ab2000 vs. 2010): 9 from 2000 to 9 from 2010. The presence of genes putatively associated with phage resistance was detected. Genes detected were associated with an abortive infection system, restriction–modification system, genes predicted to be associated with defense systems but with unknown function, and CRISPR-Cas system. Between 118 and 171 genes were found in the 18 clinical strains. On average, 26% of these genes were detected inside genomic islands in the 2000 strains and 32% in the 2010 strains. Furthermore, 38 potential CRISPR arrays in 17 of 18 of the strains were found, as well as 705 proteins associated with CRISPR-Cas systems. A moderately higher presence of these genes in the strains of 2010 in comparison with those of 2000 was found, especially those related to the restriction–modification system and CRISPR-Cas system. The presence of these genes in genomic islands at a higher rate in the strains of 2010 compared with those of 2000 was also detected. Whole-genome sequencing and bioinformatics could be powerful tools to avoid drawbacks when a personalized therapy is applied. In this study, it allows us to take care of the phage resistance in A. baumannii clinical strains to prevent a failure in possible phage therapy.This study was funded by grants PI16/01163 and PI19/00878 awarded to MT within the State Plan for R + D + I 2013–2016 (National Plan for Scientific Research, Technological Development and Innovation 2008–2011) and co-financed by the ISCIII-Deputy General Directorate of evaluation and Promotion of Research-European Regional Development Fund “A way of Making Europe” and Instituto de Salud Carlos III FEDER.

CRISPR-Cas, a Revolution in the Treatment and Study of ESKAPE Infections: Pre-Clinical Studies

This article belongs to the Special Issue Non-antimicrobial Agents as Adjuvants against Bacterial Infections[Abstract] One of the biggest threats we face globally is the emergence of antimicrobial-resistant (AMR) bacteria, which runs in parallel with the lack in the development of new antimicrobials. Among these AMR bacteria pathogens belonging to the ESKAPE group can be highlighted (Enterococcus spp., Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa and Enterobacter spp.) due to their profile of drug resistance and virulence. Therefore, innovative lines of treatment must be developed for these bacteria. In this review, we summarize the different strategies for the treatment and study of molecular mechanisms of AMR in the ESKAPE pathogens based on the clustered regularly interspaced short palindromic repeats (CRISPR) and CRISPR-associated (Cas) proteins’ technologies: loss of plasmid or cellular viability, random mutation or gene deletion as well directed mutations that lead to a gene’s loss of function.This study was funded by grants PI16/01163 and PI19/00878 awarded to M.

Phenotypic and Genomic Comparison of Klebsiella pneumoniae Lytic Phages: vB_KpnM-VAC66 and vB_KpnM-VAC13

[Abstract] Klebsiella pneumoniae is a human pathogen that worsens the prognosis of many immunocompromised patients. Here, we annotated and compared the genomes of two lytic phages that infect clinical strains of K. pneumoniae (vB_KpnM-VAC13 and vB_KpnM-VAC66) and phenotypically characterized vB_KpnM-VAC66 (time of adsorption of 12 min, burst size of 31.49 ± 0.61 PFU/infected cell, and a host range of 20.8% of the tested strains). Transmission electronic microscopy showed that vB_KpnM-VAC66 belongs to the Myoviridae family. The genomic analysis of the phage vB_KpnM-VAC66 revealed that its genome encoded 289 proteins. When compared to the genome of vB_KpnM-VAC13, they showed a nucleotide similarity of 97.56%, with a 93% of query cover, and the phylogenetic study performed with other Tevenvirinae phages showed a close common ancestor. However, there were 21 coding sequences which differed. Interestingly, the main differences were that vB_KpnM-VAC66 encoded 10 more homing endonucleases than vB_KpnM-VAC13, and that the nucleotidic and amino-acid sequences of the L-shaped tail fiber protein were highly dissimilar, leading to different three-dimensional protein predictions. Both phages differed significantly in their host range. These viruses may be useful in the development of alternative therapies to antibiotics or as a co-therapy increasing its antimicrobial potential, especially when addressing multidrug resistant (MDR) pathogens.This study was funded by grants PI19/00878 awarded to M.
