Influencia de la flexibilidad isquiosural en la potencia de salto en niños de 8 a 10 años

This study investigated the relationship between hamstring flexibility and jumping power in children aged 8 to 10 years, with the aim of improving understanding of the factors affecting physical performance at this stage of development. Seventy children were randomly selected and divided into two groups: an experimental group and a control group. Flexibility and jumping power tests were carried out before and after a three-month treatment in the experimental group, which consisted of a hamstring stretching program. The results were analyzed using Analysis of Variance (ANOVA), demonstrating that children with greater hamstring flexibility also had better performance in vertical jump. This study supports the implementation of hamstring flexibility intervention programs in children's physical education, to enhance physical performance and prevent possible injuries. However, more research is needed to consider other potentially influential factors, such as muscle strength and exercise technique.Este estudio investigó la relación entre la flexibilidad isquiosural y la potencia de salto en niños de 8 a 10 años, con el fin de mejorar la comprensión de los factores que afectan el rendimiento físico en esta etapa de desarrollo. Setenta niños fueron seleccionados al azar y divididos en dos grupos: un grupo experimental y un grupo de control. Las pruebas de flexibilidad y potencia de salto se realizaron antes y después de un tratamiento de tres meses en el grupo experimental, que consistió en un programa de estiramientos de los isquiotibiales. Los resultados fueron analizados mediante el Análisis de Varianza (ANOVA), demostrando que los niños con mayor flexibilidad isquiosural también presentaban un mejor rendimiento en el salto vertical. Este estudio respalda la implementación de programas de intervención de flexibilidad isquiosural en la educación física de los niños, para potenciar el rendimiento físico y prevenir posibles lesiones. Sin embargo, se necesita más investigación para considerar otros factores potencialmente influyentes, como la fuerza muscular y la técnica de los ejercicios. &nbsp

Clonal chromosomal mosaicism and loss of chromosome Y in elderly men increase vulnerability for SARS-CoV-2

The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, COVID-19) had an estimated overall case fatality ratio of 1.38% (pre-vaccination), being 53% higher in males and increasing exponentially with age. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, we found 133 cases (1.42%) with detectable clonal mosaicism for chromosome alterations (mCA) and 226 males (5.08%) with acquired loss of chromosome Y (LOY). Individuals with clonal mosaic events (mCA and/or LOY) showed a 54% increase in the risk of COVID-19 lethality. LOY is associated with transcriptomic biomarkers of immune dysfunction, pro-coagulation activity and cardiovascular risk. Interferon-induced genes involved in the initial immune response to SARS-CoV-2 are also down-regulated in LOY. Thus, mCA and LOY underlie at least part of the sex-biased severity and mortality of COVID-19 in aging patients. Given its potential therapeutic and prognostic relevance, evaluation of clonal mosaicism should be implemented as biomarker of COVID-19 severity in elderly people. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, individuals with clonal mosaic events (clonal mosaicism for chromosome alterations and/or loss of chromosome Y) showed an increased risk of COVID-19 lethality

NEOTROPICAL CARNIVORES: a data set on carnivore distribution in the Neotropics

Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential ecological integrity in landscapes where they occur. Carnivores also hold high conservation value and their habitat requirements can guide management and conservation plans. The order Carnivora has 84 species from 8 families in the Neotropical region: Canidae; Felidae; Mephitidae; Mustelidae; Otariidae; Phocidae; Procyonidae; and Ursidae. Herein, we include published and unpublished data on native terrestrial Neotropical carnivores (Canidae; Felidae; Mephitidae; Mustelidae; Procyonidae; and Ursidae). NEOTROPICAL CARNIVORES is a publicly available data set that includes 99,605 data entries from 35,511 unique georeferenced coordinates. Detection/non-detection and quantitative data were obtained from 1818 to 2018 by researchers, governmental agencies, non-governmental organizations, and private consultants. Data were collected using several methods including camera trapping, museum collections, roadkill, line transect, and opportunistic records. Literature (peer-reviewed and grey literature) from Portuguese, Spanish and English were incorporated in this compilation. Most of the data set consists of detection data entries (n = 79,343; 79.7%) but also includes non-detection data (n = 20,262; 20.3%). Of those, 43.3% also include count data (n = 43,151). The information available in NEOTROPICAL CARNIVORES will contribute to macroecological, ecological, and conservation questions in multiple spatio-temporal perspectives. As carnivores play key roles in trophic interactions, a better understanding of their distribution and habitat requirements are essential to establish conservation management plans and safeguard the future ecological health of Neotropical ecosystems. Our data paper, combined with other large-scale data sets, has great potential to clarify species distribution and related ecological processes within the Neotropics.
