Las propiedades psicométricas de la versión inicial del cuestionario de orientación a la tarea y al ego (teosq) adaptado a la educación física en su traducción al castellano

El propósito de este trabajo es analizar las propiedades psicométricas de la versión inicial del cuestionario TEOSQ, en su traducción al castellano, aplicado al contexto de la educación física escolar y adaptado a tal efecto. Con ello se pretende determinar si constituye un instrumento válido y fiable para utilizar en futuras investigaciones del ámbito de la educación física escolar en el contexto español. El cuestionario se administró a 774 estudiantes valencianos de E.S.O. de edades comprendidas entre los 12 y los 16 años. El análisis factorial confirmatorio (CFA) apoyó el modelo teórico hipotetizado de dos factores ('orientación a la tarea' y 'orientación al ego') para la escala del TEOSQ. La baja correlación entre los factores demostró la independencia de los mismos y los coeficientes alfa mostraron una consistencia interna aceptable de las dos subescalas. Las pruebas t indican que existen diferencias significativas por género de tal manera que los alumnos, en comparación con las alumnas, presentan una mayor orientación al ego.The purpose of this paper is to analyse the psychometric properties of the Physical Education-Adapted Task and Ego Orientation in Sport Questionnaire (TEOSQ) in its initial Spanish language version applied within the context of and adapted to physical education in schools. The paper aims to determine whether the Questionnaire can be considered a valid and reliable instrument in future research on physical education in Spanish schools. The questionnaire was administered to 774 Valencian secondary school students between the ages of 12 and 16 years old. The Confirmatory Factor Analysis (CFA) supported the hypothesized theoretical model of two factors ('task orientation' and 'ego orientation') in the TEOSQ scale. The low correlation between factors showed their independence and alfa coefficients indicated the acceptable internal consistency of both subscales. T-tests indicated that males were more ego-oriented than females

El objetivo de la asignatura es que el alumnado disfrute de la literatura, conozca nuestros referentes culturales, fomente el placer de la lectura y adquiera una sólida educación literaria en valenciano. Por esta razón, pensamos que el recurso de la revista literaria propiciará las herramientas necesarias para un óptimo aprendizaje de la lengua y de la literatura.The didactic use of ICT in literature classes nowadays represents one of the most commonly used resources in the implementation of new methodology in language teaching-learning within the Common European Framework. For this reason, starting with knowledge acquisition that is eminently meaningful, we propose this didactic experience in learning Valencian in the subject “Formació Literària per a Mestres”, assigned to the achievement of the training certificate for teaching in Valencia. The goal of the course is for students to enjoy literature, to learn about our cultural references, to foster pleasure in reading and to acquire a solid literary education in Valencian. Therefore, we believe that the resource of the literary Magazine will provide the necessary tools to study the language and the literature in an optimum way.Educació

Three-dimensional geometric morphometrics of thorax-pelvis covariation and its potential for predicting the thorax morphology: A case study on Kebara 2 Neandertal

The skeletal torso is a complex structure of outstanding importance in understanding human body shape evolution, but reconstruction usually entails an element of subjectivity as researchers apply their own anatomical expertise to the process. Among different fossil reconstruction methods, 3D geometric morphometric techniques have been increasingly used in the last decades. Two-block partial least squares analysis has shown great potential for predicting missing elements by exploiting the covariation between two structures (blocks) in a reference sample: one block can be predicted from the other one based on the strength of covariation between blocks. The first aim of this study is to test whether this predictive approach can be used for predicting thorax morphologies from pelvis morphologies within adult Homo sapiens reference samples with known covariation between the thorax and the pelvis. The second aim is to apply this method to Kebara 2 Neandertal (Israel, ∼60 ka) to predict its thorax morphology using two different pelvis reconstructions as predictors. We measured 134 true landmarks, 720 curve semilandmarks, and 160 surface semilandmarks on 60 3D virtual torso models segmented from CT scans. We conducted three two-block partial least squares analyses between the thorax (block 1) and the pelvis (block 2) based on the H. sapiens reference samples after performing generalized Procrustes superimposition on each block separately. Comparisons of these predictions in full shape space by means of Procrustes distances show that the male-only predictive model yields the most reliable predictions within modern humans. In addition, Kebara 2 thorax predictions based on this model concur with the thorax morphology proposed for Neandertals. The method presented here does not aim to replace other techniques, but to rather complement them through quantitative prediction of a virtual 'scaffold' to articulate the thoracic fossil elements, thus extending the potential of missing data estimation beyond the methods proposed in previous works

Anatomic variations of the popliteal artery branches in present Spaniard population

The popliteal region presents a wide range of vascular anomalies. The correct diagnosis of these anatomical variations plays a key role in success of diverse surgical procedures. In this context, the aim of our study was to investigate the prevalence of the anatomic patterns of the popliteal artery branches in a sample of present Spaniard population. This is a retrospective single-center study. 1633 (97.72%) computed tomography angiography images of the popliteal artery branches were studied from a total sample of 840 Spaniard subjects that underwent a computed tomography angiography study, 695 males (82.73%) and 145 women (17.26%), aged between 18 and 97 years. The applied statistics were multivariate models for repeated measures, Student’s t-test, and Pearson’s chi-square test. Our results show that the Kim’s et al. (1989) IA (“normal” pattern) was observed in 1507 limbs (92.28%), while the IB and IC were observed in 24 (1.46%) and 6 (0.36%) limbs respectively. The IIA-1 and IIA-2 patterns were observed in 19 (1.16%) and 27 (1.65%) subjects, while the IIB and IIC in 15 (0.91%) and 1 (0.06%) subjects. Finally, the IIIA, IIIB, IIIC patterns were observed in 24 (1.46%), 5 (0.30%) and 5 (0.30%) subjects respectively. There were no significant differences between men and women, nor between the right and left limbs. In conclusion, approximately 8% of Spaniard subjects present branching anatomic patterns of the popliteal artery different of the normal IA pattern, thus it should be taken into account in clinical practice

Assessing thoraco‐pelvic covariation in Homo sapiens and Pan troglodytes: A 3D geometric morphometric approach

Objectives Understanding thoraco‐pelvic integration in Homo sapiens and their closest living relatives (genus Pan) is of great importance within the context of human body shape evolution. However, studies assessing thoraco‐pelvic covariation across Hominoidea species are scarce, although recent research would suggest shared covariation patterns in humans and chimpanzees but also species‐specific features, with sexual dimorphism and allometry influencing thoraco‐pelvic covariation in these taxa differently. Material and Methods N = 30 adult H. sapiens and N = 10 adult Pan troglodytes torso 3D models were analyzed using 3D geometric morphometrics and linear measurements. Effects of sexual dimorphism and allometry on thoraco‐pelvic covariation were assessed via regression analyses, and patterns of thoraco‐pelvic covariation in humans and chimpanzees were computed via Two‐Block Partial Least Squares analyses. Results Results confirm the existence of common aspects of thoraco‐pelvic covariation in humans and chimpanzees, and also species‐specific covariation in H. sapiens that is strongly influenced by sexual dimorphism and allometry. Species‐specific covariation patterns in chimpanzees could not be confirmed because of the small sample size, but metrics point to a correspondence between the most caudal ribs and iliac crest morphology that would be irrespective of sex. Conclusions This study suggests that humans and chimpanzees share common aspects of thoraco‐pelvic covariation but might differ in others. In humans, torso integration is strongly influenced by sexual dimorphism and allometry, whilst in chimpanzees it may not be. This study also highlights the importance not only of torso widths but also of torso depths when describing patterns of thoraco‐pelvic covariation in primates. Larger samples are necessary to support these interpretations

Association between ribs shape and pulmonary function in patients with Osteogenesis Imperfecta

The aim of the present study was to test the hypothesis that ribs shape changes in patients with OI are more relevant for respiratory function than thoracic spine shape. We used 3D geometric morphometrics to quantify rib cage morphology in OI patients and controls, and to investigate its relationship with forced vital capacity (FVC) and forced expiratory volume in 1 s (FEV1), expressed as absolute value and as percentage of predicted value (% pred). Regression analyses on the full sample showed a significant relation between rib shape and FEV1, FVC and FVC % pred whereas thoracic spine shape was not related to any parameter. Subsequent regression analyses on OI patients confirmed significant relations between dynamic lung volumes and rib shape changes. Lower FVC and FEV1 values are identified in OI patients that present more horizontally aligned ribs, a greater antero-posterior depth due to extreme transverse curve at rib angles and a strong spine invagination, greater asymmetry, and a vertically short, thoracolumbar spine, which is relatively straight in at levels 1–8 and shows a marked kyphosis in the thoraco-lumbar transition. Our research seems to support that ribs shape is more relevant for ventilator mechanics in OI patients than the spine shapeThis project was funded by grants of the Fundacion Eresa (grant number: BF14_005), the Ministry of Economy, Industry and Competitiveness (grant number: CGL2015-63648-P), the Care4Brittlebones Foundation (grant number: OTR2016-15543INVES), and the University of Valencia (grant number: UV-INV_AE18-773873)

Persistence of Innate Immune Pathways in Late Stage Human Bacterial and Fungal Keratitis: Results from a Comparative Transcriptome Analysis

Microbial keratitis (MK) is a major cause of blindness worldwide. Despite adequate antimicrobial treatment, tissue damage can ensue. We compared the human corneal transcriptional profile in late stage MK to normal corneal tissue to identify pathways involved in pathogenesis. Total RNA from MK tissue and normal cadaver corneas was used to determine transcriptome profiles with Illumina HumanHT-12 v4 beadchips. We performed differential expression and network analysis of genes in bacterial keratitis (BK) and fungal keratitis (FK) compared with control (C) samples. Results were validated by RTqPCR for 45 genes in an independent series of 183 MK patients. For the microarray transcriptome analysis, 27 samples were used: 12 controls, 7 BK culture positive for Streptococcus pneumoniae (n = 6), Pseudomonas aeruginosa (n = 1), and 8 FK, culture positive for Fusarium sp. (n = 5), Aspergillus sp. (n = 2), or Lasiodiplodia sp. (n = 1). There were 185 unique differentially expressed genes in BK, 50 in FK, and 339 common to both [i.e., genes with fold-change (FC) < −4 or ≥4 and false discovery rate (FDR) adjusted P < 0.05]. MMP9 had the highest FC in BK (91 FC, adj p = 3.64 E-12) and FK (FC 64, adj. p = 6.10 E-11), along with other MMPs (MMP1, MMP7, MMP10, MMP12), pro-inflammatory cytokines (IL1B, TNF), and PRRs (TLR2, TLR4). HIF1A and its induced genes were upregulated uniquely in BK. Immune/defense response and extracellular matrix terms were the most enriched Gene Ontology terms in both BK and FK. In the network analysis, chemokines were prominent for FK, and actin filament reorganization for BK. Microarray and RTqPCR results were highly correlated for the same samples tested with both assays, and with the larger RTqPCR series. In conclusion, we found a great deal of overlap in the gene expression profile of late stage BK and FK, however genes unique to fungal infection highlighted a corneal epithelial wound healing response and for bacterial infection the prominence of HIF1A-induced genes. These sets of genes may provide new targets for future research into therapeutic agents
