Efecto agudo de la actividad fisicodeportiva y la expresión corporal sobre el estado de ánimo

Este trabajo analiza los efectos de una sesión de actividad fisicodeportiva y otra de expresión corporal sobre el estado de ánimo en un grupo de 92 adolescentes de la ciudad de Málaga (España), con edades entre los 14 y 16 años (M=14,87; DT= 0,79). En él se sigue una metodología cuasiexperimental con un diseño de tipo pre-post con grupos no equivalentes, en el que existen dos grupos experimentales que han sido sometidos a una sesión de deportes de raqueta y a otra de aeróbic. Se ha utilizado el cuestionario Profile of Mood States (POMS - McNair, Lorr, & Droppleman, 1971) para analizar los siguientes factores: tensión-ansiedad, depresión-melancolía, angustia hostilidad-cólera, vigor-actividad, fatiga-inercia y confusión-orientación. Los resultados indican que, tras la intervención, el estado de ánimo mejora en ambos grupos experimentales, observándose un efecto significativo en aquellos grupos que practican actividad física

Evaluating mating compatibility within fruit fly cryptic species complexes and the potential role of sex pheromones in pre-mating isolation

The study of sexual behavior and the identification of the signals involved in mate recognition between con-specifics are key components that can shed some light, as part of an integrative taxonomic approach, in delimitating species within species complexes. In the Tephritidae family several species complexes have received particular attention as they include important agricultural pests such as the Ceratitis fasciventris(Bezzi), Ceratitis anonae (Graham) and Ceratitis rosa Karsch (FAR) complex, the Bactrocera dorsalis(Hendel) complex and the Anastrepha fraterculus (Wiedemann) complex. Here the value and usefulness of a methodology that uses walk-in field cages with host trees to assess, under semi-natural conditions, mating compatibility within these complexes is reviewed, and the same methodology to study the role of chemical communication in pre-mating isolation among Anastrepha fraterculus populations is used. Results showed that under the same experimental conditions it was possible to distinguish an entire range of different outcomes: from full mating compatibility among some populations to complete assortative mating among others. The effectiveness of the methodology in contributing to defining species limits was shown in two species complexes: Anastrepha fraterculus and Bactrocera dorsalis, and in the case of the latter the synonymization of several established species was published. We conclude that walk-in field cages constitute a powerful tool to measure mating compatibility, which is also useful to determine the role of chemical signals in species recognition. Overall, this experimental approach provides a good source of information about reproductive boundaries to delimit species. However, it needs to be applied as part of an integrative taxonomic approach that simultaneously assesses cytogenetic, molecular, physiological and morphological traits in order to reach more robust species delimitations.Fil: Juárez, María Laura.

O tipo de esporte praticado determina o nível de atenção seletiva em adultos jovens

The main purpose of this study was to determine the differences in selective attention between people who regularly practiced different forms of physical-sports activity. The sample consisted of a total of 1,038 participants, 68.30% (n=709) being women and 31.70% (n=329) being men, aged between 20 and 29 years (M ± SD = 22.54 ± 2.35). The evaluate selective attention, a computerized numerical cross-out test (a 5x5 matrix) was used, which is part of the Attentional Processes software and is hosted on the MenPas 1.0 Psychosocial Assessment Platform. (www.menpas.com). The results highlighted the existence of statistically significant differences between the types of sport in the execution time of the test performed. Specifically, individual sports practitioners spent more time performing the task than those who performed team sports (Z= −2.46; p= .014, Cohen'sd= .23, 95% CI (.07, .38)) or adversary (Z= −2.11; p= .035, Cohen'sd= .19, 95% CI (.01, .38)). Specifically, those who played paddle tennis and soccer were the ones who obtained the best execution times. The results obtained highlighted that the type of sport practiced could have a differential impact on cognitive development, specifically on selective attention.

A novel targeted RNA-Seq panel identifies a subset of adult patients with acute lymphoblastic leukemia with BCR-ABL1-like characteristics

BCR-ABL1-like B-cell precursor acute lymphoblastic leukemia (BCP-ALL) remains poorly characterized in adults. We sought to establish the frequency and outcome of adolescent and adult BCR-ABL1-like ALL using a novel RNA-Seq signature in a series of patients with BCP-ALL. To this end, we developed and tested an RNA-Seq custom panel of 42 genes related to a BCR-ABL1-like signature in a cohort of 100 patients with BCP-ALL and treated with risk-adapted ALL trials. Mutations related to BCR-ABL1-like ALL were studied in a panel of 33 genes by next-generation sequencing (NGS). Also, CRLF2 overexpression and IKZF1/CDKN2A/B deletions were analyzed. Twenty out of 79 patients (12-84 years) were classified as BCR-ABL1-like (25%) based on heatmap clustering, with significant overexpression of ENAM, IGJ, and CRLF2 (P ≤ 0.001). The BCR-ABL1-like subgroup accounted for 29% of 15-60-year-old patients, with the following molecular characteristics: CRLF2 overexpression (75% of cases), IKZF1 deletions (64%), CDKN2A/B deletions (57%), and JAK2 mutations (57%). Among patients with postinduction negative minimal residual disease, those with the BCR-ABL1-like ALL signature had a higher rate of relapse and lower complete response duration than non-BCR-ABL1-like patients (P = 0.007). Thus, we have identified a new molecular signature of BCR-ABL1-like ALL that correlates with adverse prognosis in adult patients with ALL

Dust Lifting Through Surface Albedo Changes at Jezero Crater, Mars

We identify temporal variations in surface albedo at Jezero crater using first-of-their-kind high-cadence in-situ measurements of reflected shortwave radiation during the first 350 sols of the Mars 2020 mission. Simultaneous Mars Environmental Dynamics Analyzer (MEDA) measurements of pressure, radiative fluxes, winds, and sky brightness indicate that these albedo changes are caused by dust devils under typical conditions and by a dust storm at Ls ∼ 155°. The 17% decrease in albedo caused by the dust storm is one order of magnitude larger than the most apparent changes caused during quiescent periods by dust devils. Spectral reflectance measurements from Mastcam-Z images before and after the storm indicate that the decrease in albedo is mainly caused by dust removal. The occurrence of albedo changes is affected by the intensity and proximity of the convective vortex, and the availability and mobility of small particles at the surface. The probability of observing an albedo change increases with the magnitude of the pressure drop (ΔP): changes were detected in 3.5%, 43%, and 100% of the dust devils with ΔP 2.5 Pa and ΔP > 4.5 Pa, respectively. Albedo changes were associated with peak wind speeds above 15 m·s−1. We discuss dust removal estimates, the observed surface temperature changes coincident with albedo changes, and implications for solar-powered missions. These results show synergies between multiple instruments (MEDA, Mastcam-Z, Navcam, and the Supercam microphone) that improve our understanding of aeolian processes on Mars.This research has been funded by the Comunidad de Madrid Project S2018/NMT-4291 (TEC2SPACE-CM), by the Spanish State Research Agency (AEI) Project MDM-2017-0737 Unidad de Excelencia “María de Maeztu”- Centro de Astrobiología (CSIC/INTA), by the Spanish Ministry of Science and Innovation (MCIN)/State Agency of Research (10.13039/501100011033) project RTI2018-098728-B-C31, and by the project PID2021-126719OB-C41, funded by MCIN/AEI/10.13039/501100011033/FEDER, UE.
