Spanish validation of the locus of control questionnaire in sport for children

El locus de control ha sido estudiado en el deporte, sin embargo no existía un instrumento válido para evaluarlo en deporte infantil. Este estudio lleva a cabo la validación española del Children´s Sport Locus of Control Scale (CSLCS) que desarrollaron Tsai y Hsieh (2015). La adaptación presenta dos fases: una primera exploratoria con 248 niños entre 7 y 16 años para observar el comportamiento cualitativo de los ítems; y una segunda con 221 deportistas entre 8 y 22 años en la que se modificó el cuestionario para ajustarlo a los resultados obtenidos. Se obtiene una escala final de 10 ítems, con 5 ítems por dimensión (interna y externa), que presenta un ajuste adecuado. Los resultados demuestran que la versión española de la escala posee cualidades psicométricas adecuadas para ser utilizada en la investigación y la práctica aplicada en la evaluación deportiva infantilLocus of control has been studied in the sport context, however there was no valid instrument to evaluate it in children's sport. This study adapts into Spanish and validates the Children's Locus of Control Scale for Sport (CSLCS) in the Spanish language. This CSLCS was developed by Tsai y Hsieh (2015). The adaptation has two phases: an initial screening of 248 children between the ages of 7 and 16 to observe the qualitative behavior of the items; and a second one with 221 athletes with children between the ages of 8 and 22 in which the questionnaire was modified to fit the results. A final 10-item scale was obtained, with 5 items per dimension (internal and external), which presents an adequate fit. Results show that the Spanish version of the scale possesses adequate psychometric qualities for its use in research and applied fields in child´s sport evaluatio

Measurement invariance of the Satisfaction with Life Scale by sexual orientation

The Satisfaction with Life Scale (SWLS) has shown strong evidence of reliability, validity, and gender invariance, and there is some evidence of invariance across age, culture, and educational levels. So far, invariance across sexual orientation has not been studied, despite the number of works that relate well-being to sexual orientation. The SWLS should be invariant across sexual orientation to be able to compare group means. This study aimed to explore the invariance of the SWLS across sexual orientation. A non-probabilistic sample with 553 Spanish adults (208 males, 345 females; 212 heterosexuals, 182 gays, and 138 bisexuals among other sexual orientations) participated in a survey. We tested a one-factor model using confirmatory factor analysis. We tested the configural, metric, and scalar invariance of the factorial structure of the SWLS across sexual orientation with heterosexual, lesbian/gay, and bisexual groups. According to our results, the Spanish version of the SWLS shows scalar invariance across sexual orientations, allowing a valid comparison between sexual minority and heterosexual people. Moreover, in our sample, lesbian/gay and bisexual participants obtained lower scores in life satisfaction than heterosexual participants. Bisexual people obtained the lowest score in well-being compared with the other groups. Implications related to the importance of checking instrument invariance before comparing mean differences between groups are discussed.info:eu-repo/semantics/publishedVersio

Characterization of basal pseudopod-like processes in ileal and colonic PYY cells.

The peptide tyrosine tyrosine (PYY) is produced and secreted from L cells of the gastrointestinal mucosa. To study the anatomy and function of PYY-secreting L cells, we developed a transgenic PYY-green fluorescent protein mouse model. PYY-containing cells exhibited green fluorescence under UV light and were immunoreactive to antibodies against PYY and GLP-1 (glucagon-like peptide-1, an incretin hormone also secreted by L cells). PYY-GFP cells from 15 μm thick sections were imaged using confocal laser scanning microscopy and three-dimensionally (3D) reconstructed. Results revealed unique details of the anatomical differences between ileal and colonic PYY-GFP cells. In ileal villi, the apical portion of PYY cells makes minimal contact with the lumen of the gut. Long pseudopod-like basal processes extend from these cells and form an interface between the mucosal epithelium and the lamina propria. Some basal processes are up to 50 μm in length. Multiple processes can be seen protruding from one cell and these often have a terminus resembling a synapse that appears to interact with neighboring cells. In colonic crypts, PYY-GFP cells adopt a spindle-like shape and weave in between epithelial cells, while maintaining contact with the lumen and lamina propria. In both tissues, cytoplasmic granules containing the hormones PYY and GLP-1 are confined to the base of the cell, often filling the basal process. The anatomical arrangement of these structures suggests a dual function as a dock for receptors to survey absorbed nutrients and as a launching platform for hormone secretion in a paracrine fashion

Social campaigns to encourage responsible fashion consumption: qualitative study with university students

A fruitful line of research on responsible consumption has recently emerged due to a concern for and interest in environmental issues and the growing resource depletion, providing an opportunity for communications to influence human behavior toward environmental protection. This paper shows the design, implementation, and impact assessment of two social campaigns aimed to inform the public of the effects of an overconsumption of clothing and encourage responsible consumption. We designed a non-experimental, descriptive, qualitative study based on 30 semi-structured interviews with university students in Bogotá, Colombia, from variables such as campaigns’ message, behavioral intentions, and relationship with the social and environmental context. The results show the students’ unawareness of overconsumption but suggest a positive impact on their intentions to increase responsible apparel consumption. This study contributes to empirical knowledge of better alternatives for effective messages that favor responsible consumption.En los últimos años se ha desarrollado una fructífera línea de investigación en consumo responsable debido a la preocupación y el interés por el problema ambiental y el creciente deterioro de los recursos naturales, lo que representa un campo de trabajo para la comunicación en su posibilidad de influir en el comportamiento humano a favor del cuidado y protección del ambiente. Este trabajo presenta el diseño, desarrollo y evaluación de impacto de dos campañas sociales orientadas a informar sobre los efectos del consumo desmedido de prendas de vestir y fortalecer el consumo responsable de este tipo de productos. Se diseñó un estudio no experimental, descriptivo y de carácter cualitativo, basado en 30 entrevistas semiestructuradas a estudiantes universitarios en Bogotá (Colombia), a partir de variables como el mensaje de las campañas, las intenciones conductuales y la relación con el contexto social y ambiental. Los hallazgos evidencian desconocimiento acerca del problema derivado del consumo excesivo de prendas de vestir, aunque sugieren un impacto positivo respecto a las posibles intenciones comportamentales a favor del consumo responsable de ropa. Esta investigación aporta al conocimiento empírico sobre alternativas en la construcción de mensajes efectivos para coadyuvar al consumo responsable

Classical swine fever virus: the past, present and future

Classical swine fever (CSF) is among the most relevant viral epizootic diseases of swine. Due to its severe economic impact, CSF is notifiable to the world organisation for animal health. Strict control policies, including systematic stamping out of infected herds with and without vaccination, have permitted regional virus eradication. Nevertheless, CSF virus (CSFV) persists in certain areas of the world and has re-emerged regularly. This review summarizes the basic established knowledge in the field and provides a comprehensive and updated overview of the recent advances in fundamental CSFV research, diagnostics and vaccine development. It covers the latest discoveries on the genetic diversity of pestiviruses, with implications for taxonomy, the progress in understanding disease pathogenesis, immunity against acute and persistent infections, and the recent findings in virus-host interactions and virulence determinants. We also review the progress and pitfalls in the improvement of diagnostic tools and the challenges in the development of modern and efficacious marker vaccines compatible with serological tests for disease surveillance. Finally, we highlight the gaps that require research efforts in the future.info:eu-repo/semantics/publishedVersio

LACTATO SANGUINEO Y FRECUENCIA CARDIACA DE REPOSO DE MUJERES ADOLESCENTES MARCHISTAS

El objetivo de la investigación describir la dinámica del ácido láctico pre - post entrenamiento en controles y competencias en deportistas jóvenes, metodológicamente es una investigación de tipo longitudinal cuantitativa midiendo la frecuencia cardiaca y el ácido láctico. Los Materiales para la medición del ácido láctico se usó medidor Acuesport y la frecuencia cardiaca de reposo tomada con pulsómetros Polar antes del entrenamiento; durante el período preparatorio (enero 26 a abril 25 de 1999) del entrenamiento, aplicado a tres marchistas del género femenino de 14 a 15 años; de la EIDE de la ciudad de la Habana – Cuba. Los antecedentes en la revisión muestran la información en cuanto a este tema insuficiente, ya que, si se quiere llegar a precisar el entrenamiento con adolescentes y especialmente en la marcha deportiva, no se puede seguir basándose en las programaciones, planes e indicadores funcionales y bioquímicos de los adultos, para adaptarlos y aplicarlos en adolescentes. Sabiendo que el ácido láctico que se encuentra en sangre es aproximadamente del 50% del producido, encontrándose este porcentaje influido por la capacidad aerobia, efectos residuales de la fatiga, la temperatura y otras variables como la edad biológica, los resultados en el estudio muestra los valores de ácido láctico de reposo, oscilan entre 2,3 y 2,8 m.mol/l (media) y la media de los valores post carga, oscilan entre 7.9 y 13.3 m.mol/l. En conclusión, se pueden ver valores que muestran actividad del metabolismo aerobio y hasta valores que muestra gran participación de la producción de energía anaerobia

Quinine localizes to a non-acidic compartment within the food vacuole of the malaria parasite Plasmodium falciparum

Abstract Background The naturally fluorescent compound quinine has long been used to treat malaria infections. Although some evidence suggests that quinine acts in the parasite food vacuole, the mechanism of action of quinine has not yet been resolved. The Plasmodium falciparum multidrug resistance (pfmdr1) gene encodes a food vacuolar membrane transporter and has been linked with parasite resistance to quinine. The effect of multiple pfmdr1 copies on the subcellular localization of quinine was explored. Methods Fluorescence microscopy was used to evaluate the subcellular localization of quinine in parasites containing different pfmdr1 copy numbers to determine if copy number of the gene affects drug localization. The acidotropic dye LysoTracker Red was used to label the parasite food vacuole. Time-lapse images were taken to determine quinine localization over time following quinine exposure. Results Regardless of pfmdr1 copy number, quinine overlapped with haemozoin but did not colocalize with LysoTracker Red, which labeled the acidic parasite food vacuole. Conclusions Quinine localizes to a non-acidic compartment within the food vacuole possibly haemozoin. Pfmdr1 copy number does not affect quinine subcellular localization
