Configuración Dermatoglífica, ACTN3 y ECA: Un estudio transcultural en deportistas de diferentes Disciplinas (Dermatoglyphic Configuration, ACTN3 and ECA: A transcultural study in athletes of different Disciplines)

El rendimiento físico se ha asociado con diferentes variantes genéticas. El objetivo de este estudio fue determinar la asociación entre características dermatoglíficas y los genotipos ACTN3 y ECA. La muestra la constituyen 82 seleccionados nacionales de diferentes modalidades deportivas de Brasil, Japón y Chile. Los marcadores ACTN3 y ECA se obtuvieron a través de una muestra de saliva y se analizaron mediante el empleo de cadena de la polimerasa en tiempo real a partir del iQ5ThermalCycler, BioRad, mientras que para la configuración dermatoglifica se utilizó un lector de huella digital Verifier® 320 LC 2.0. Estos deportistas fueron clasificados en grupos de acuerdo a la configuración de sus patrones dermatoglíficos (A, L, W, D10 y SQTL) en los siguientes grupos: aeróbicos (n= 27); anaeróbicos (n= 55). En cuanto a la frecuencia de aparición de polimorfismos, para ambos grupos predomina el genotipo RX 48,0% y 49,1% de ACTN3, y DI 68,0% y 41,3% para ECA, en los grupos aeróbico y anaeróbico respectivamente. En el grupo aeróbico se observa una asociación muy alta entre ACTN3 con presilla, verticilo y D10 (r=0,90), en el grupo anaeróbico solo observa asociación alta en presilla (r=0,77), para el gen ECA se observan asociaciones moderadas entre presilla, verticilo y D10 (r=0,45), en el grupo aeróbico. Conclusión: Las características dermatoglíficas pueden estar asociados con la variante alélica del gen ACTN3 (RR) y ECA (DI), para perfiles deportivos de carácter anaeróbico. Abstract. Physical performance has been associated with different genetic variants. The objective of this study was to determine the association between dermatoglyphic characteristics and the ACTN3 and ECA genotypes. The sample is established by 82 national teams from different sports modalities in Brazil, Japan and Chile. The ACTN3 and ECA markers were obtained through a saliva sample and was analyzed using the polymerase chain in real time from the iQ5ThermalCycler, BioRad, while a Verifier® 320 LC fingerprint reader was used for the dermatoglyphic configuration. These athletes were classified into groups according to the configuration of their dermatoglyphic patterns (A, L, W, D10 and SQTL) in the following groups: aerobics (n = 27); anaerobic (n = 55). Regarding the frequency in the appearance of polymorphisms, the RX genotype 48.0% and 49.1% of ACTN3 predominated for both groups and DI 68.0% and 41.3% for ACE, in the aerobic and anaerobic groups respectively. In the aerobic group a very high association is observed between ACTN3 with a clip, verticil and D10 (r = 0.90), in the anaerobic group only a high association was observed in the clip (r = 0.77), for the ACE gene they are observed moderate associations between clip, verticil and D10 (r = 0.45), in the aerobic group. Conclusion: Dermatoglyphic characteristics may be associated with the allelic variant of the ACTN3 (RR) and RCT (DI) gene, for sports profiles of an anaerobic nature.

Prevalence and psychosocial predictors of cyberaggression and cybervictimization in adolescents: A Spain-Ecuador transcultural study on cyberbullying

The present study aims to collect data about the prevalence of cyberbullying and the role of self-esteem, empathy, and social skills in predicting cybervictimization and cyberaggression in two different countries: Spain and Ecuador. Additionally, it compares the similarities found in both countries. A wide sample of adolescents from Secondary Education (N = 24943; mean age = 13.92; SD = 1.30, girls = 49.9%) from both countries (Spain = 14,206 and Ecuador = 10,737) took part by filling in a set of self-reports. Weighted analyses and structural equation models were used. The results revealed that 8.8% were cybervictims, 3.1% were cyberaggressors and 4.9% cybervictims-cyberaggressors in Spain; whereas 8.7% were cybervictims, 5.1% were cyberaggressors and 14.3% were cybervictims-cyberaggressors in Ecuador. Cybervictimization could be predicted in both countries by means of self-deprecation and social skills, although the meaning of some skills was different depending on the country. Cyberaggression could be predicted in both countries by means of empathy, assertiveness, and conflict-resolution skills, as well as by communicative and relational skills. Self-deprecation was a predictor of cyberaggression only in Spain. These results are discussed, and educational inferences are drawn for prevention.
