The genetic history of Europeans.
2012
The evolutionary history of modern humans is characterized by numerous migrations driven by environmental change, population pressures, and cultural innovations. In Europe, the events most widely considered to have had a major impact on patterns of genetic diversity are the initial colonization of the continent by anatomically modern humans (AMH), the last glacial maximum, and the Neolithic transition. For some decades it was assumed that the geographical structuring of genetic diversity within Europe was mainly the result of gene flow during and soon after the Neolithic transition, but recent advances in next-generation sequencing (NGS) technologies, computer simulation modeling, and ancie…

Self-efficacy in volleyball: What has been evaluated? A systematic review
2019
Self-efficacy in sport has been the object of study in different modalities, including volleyball. The aim of the present study was to verify, by means of a systematic review, what has been evaluated in volleyball self-efficacy studies. The APA, PsycInfo, Bireme, Eric, Science Direct, Pubmed and Scopus databases were used to carry out the search. After the search, the articles were selected using the inclusion and exclusion criteria, resulting in 7 articles. The results point to a lack of clarity in the instruments for assessing self-efficacy in volleyball, with regard to the technical, tactical, physical or psychological attributes they are designed to measure. Few articles have described …

Deterioro cognitivo leve: método y procedimiento de clasificación
2012
El deterioro cognitivo leve (DCL) se presenta como una de las entidades clínicas que mayor interés despierta en el ámbito de la neurociencia cognitiva, por la dimensión de sus cifras y la posible evolución de algunos de los subtipos a demencia. Este trabajo tiene como objetivo poner a prueba un método y procedimiento de clasificación del DCL en función de las puntuaciones en las pruebas neuropsicológicas y de su convergencia con un criterio clínico establecido, así como analizar las diferencias entre los grupos resultantes. Tras la aplicación de los criterios de inclusiónexclusión, se evaluó mediante una batería de pruebas neuropsicológicas a 39 personas con edades entre 60 y 89 años. Se es…

Leaps and bounds: geographical and ecological distance constrained the colonisation of the Afrotemperate by Erica.
2018
Abstract Background The coincidence of long distance dispersal (LDD) and biome shift is assumed to be the result of a multifaceted interplay between geographical distance and ecological suitability of source and sink areas. Here, we test the influence of these factors on the dispersal history of the flowering plant genus Erica (Ericaceae) across the Afrotemperate. We quantify similarity of Erica climate niches per biogeographic area using direct observations of species, and test various colonisation scenarios while estimating ancestral areas for the Erica clade using parametric biogeographic model testing. Results We infer that the overall dispersal history of Erica across the Afrotemperate…
Topology testing of phylogenies using least squares methods
2006
[Background] The least squares (LS) method for constructing confidence sets of trees is closely related to LS tree building methods, in which the goodness of fit of the distances measured on the tree (patristic distances) to the observed distances between taxa is the criterion used for selecting the best topology. The generalized LS (GLS) method for topology testing is often frustrated by the computational difficulties in calculating the covariance matrix and its inverse, which in practice requires approximations. The weighted LS (WLS) allows for a more efficient albeit approximate calculation of the test statistic by ignoring the covariances between the distances.
Positive selection at codon 38 of the human KCNE1 (= minK) gene and sporadic absence of 38Ser-coding mRNAs in Gly38Ser heterozygotes
2009
Abstract Background KCNE1 represents the regulatory beta-subunit of the slowly activating delayed rectifier potassium channel (IKs). Variants of KCNE1 have repeatedly been linked to the long-QT syndrome (LQTS), a disorder which predisposes to deafness, ventricular tachyarrhythmia, syncope, and sudden cardiac death. Results We here analyze the evolution of the common Gly38Ser variant (rs1805127), using genomic DNAs, complementary DNAs, and HEK293-expressed variants of altogether 19 mammalian species. The between species comparison reveals that the human-specific Gly38Ser polymorphism evolved under strong positive Darwinian selection, probably in adaptation to specific challenges in the fine-…
