Alcohol Use Disorder (AUD) is among the most prevalent mental illnesses, and due to the low efficacy of the current medication, it is essential to find new biological targets that could modulate alcohol consumption. Since Galanin (1− 15) [GAL(1− 15)] produces a loss of motivational behaviour by an artificial reinforcer and decreases the preference an alcohol consumption in a voluntary alcohol intake, we have studied the role of GAL(1− 15) in alcohol-seekingbehaviourandtheinvolvementofthecorticomesolimbicsystemaswellastheroleofGAL(1− 15) in context-induced alcohol relapse. In rats, we have studied GAL(1− 15)-effects on alcohol-seeking in self- administration, in fixed-ratio (FR1) and progressive-ratio (PR), and the involvement of GAL receptors using siRNA GALR1 or GALR2 knockdown animals. We have analysed the transcriptional changes of C-Fos, dopamine receptors, GAL receptors and 5HT1A receptors in the corticomesolimbic system. Also, we have examined the effect of GAL(1− 15) in context-induced alcohol relapse. GAL(1− 15) substantially reduced alcohol-seeking behaviour in the operant self-administration model in an FR1 protocol and at the breaking point in a PR schedule. GALR1and GALR2 were involved in these effects, as indicated by the analysis by GALR2 antagonist and GALR1 and GALR2 knockdown animals. Notably, the mechanism of GAL(1− 15)-mediated actions involved changes in C-Fos, Dopamine receptors and 5HT1A expression in the ventral tegmental area, accumbens nucleus and prefrontal cortex. Significantly, GAL(1− 15) reduced the context-induced alcohol relapse. These results open up the possibility to use GAL(1− 15) as a novel strategy in AUD., This work was supported by grants awarded by Spanish Ministry of Economy PID2020-114392RB-100, PDC2021-121566-100 and by Junta de Andalucía P20-00026-R and PI-0083-2019

Previous research reports that cybervictims are more likely to experience suicidal ideations. Gratitude and life satisfaction have shown to predict suicide risk, but they have rarely been explored in the cyberbullying context. Hence, this study examined the roles of gratitude and life satisfaction in suicide risk in cyberbullying situations. An initial sample of 858 adolescents participated in a prospective study, completing questionnaires assessing gratitude, life satisfaction, cyberbullying experiences and suicidal ideation. Results showed that low levels of gratitude and life satisfaction influence suicidal ideation in cybervictimized adolescents. Limitations and implications of this study are discussed., Parte del proyecto I+D+i PID2020-117006RB-I00, financiado por MCIN/AEI/10.13039/501100011033, Parte del proyecto UMA 18-FEDERJA-147 financiado por Junta de Andalucía/Fondos FEDER, Grupo de investigación Applied Positive Lab CTS-1048G-FEDER (Junta de Andalucía)

El presente estudio tiene como objetivo la exploración de las creencias de los maestros de educación primaria en relación con 1) perder en la escuela, 2) los comportamientos de los estudiantes para hacer frente al hecho de perder y 3) estrategias para enseñar cómo hacer frente a la pérdida de forma adaptativa en la escuela. Utilizando la metodología de estudio de casos, se realizan entrevistas en profundidad y encuestas entre una muestra de profesores seleccionados a propósito con perfiles variados. Por medio del análisis de contenido, los resultados evidenciarán cómo los participantes entienden el hecho de perder en la escuela.

El presente estudio fue realizado por la profesora María Jesús García Granja, tomando como muestra a alumnos matriculados en asignaturas de primer y cuarto curso del Grado en Fundamentos de la Arquitectura de la Universidad de Málaga. Para la investigación por encuesta se utilizaron como instrumento básico cuestionarios de elaboración propia, según tablas de operacionalización prediseñadas por la autora, que permitieron recoger de forma organizada los indicadores de las variables implicadas en el objetivo de la encuesta. Dichos cuestionarios fueron distribuidos en clase de las asignaturas Introducción a Historia del Arte y de la Arquitectura (1º) y Composición Arquitectónica I (4º), para su cumplimentación voluntaria por los estudiantes que desearan colaborar en el estudio. Los formularios cumplimentados y sus respectivas autorizaciones están disponibles para su consulta previa solicitud motivada dirigida a: mjggranja@uma.es Los indicadores obtenidos tenían como finalidad la discusión de resultados y obtención de conclusiones sobre la hipótesis de su investigación, relacionada con el objetivo del proyecto de innovación educativa tipo A: PIE 19-229 “Incorporación de las nuevas tecnologías en la docencia de Arquitectura para la mejora de la experiencia formativa”, a cuyo equipo de investigadores perteneció la autora entre 2019 y 2022 (https://www.uma.es/eamtechlab/info/120816/pie-19-229/): “El objetivo de este PIE es hacer una reflexión sobre las posibilidades de su utilización en las asignaturas de las áreas de conocimiento implicadas en el título, y desarrollar su aplicación en asignaturas experimentales, que permitan servir de modelo al resto. Para ello se crea un grupo de trabajo de profesores implicados en la formación de nuevas tecnologías que permita debatir y establecer protocolos de implementación a nivel de título, todo ello con el objetivo final de mejorar la experiencia formativa del alumno.”, Universidad de Málaga

Alcohol use disorder (AUD) is highly prevalent, and over 50% of AUD patients also suffer major depressive disorders. Selective 5-HT reuptake inhibitors (SSRIs) can reduce rodent ethanol drinking but exert modest clinical efficacy in alcoholic individuals. Finding new pharmacological strategies that could modulate alcohol consumption and depression is necessary. We have analyzed the effect of Galanin (1–15) [GAL(1–15)] on escitalopram (ESC)-mediated effect in alcohol consumption using the alcohol self-administration test, the nuclei involved in the effect, and whether GAL(1–15) + ESC modulated the response in despair or anxiety tests in animals under chronic alcohol intake. GAL(1–15) + ESC combination substantially reduced alcohol intake in the alcohol self-administration test and, moreover, enhanced the reduction of reward capacity of ESC on different reinforcers such as sucrose or saccharine. GAL(1–15) + ESC coadministration significantly decreases the number of C-Fos-IR TH cell bodies in the VTA, and PCA analysis suggests that one functional network, including VTA, RMTg and DR, is involved in these effects. Significantly in rats with chronic alcohol consumption, GAL(1–15) reversed adverse ESC-mediated effects in the depression-related behavioural test and forced swimming test. The results open up the possibility of using GAL(1–15) in combination with the SSRI Escitalopram as a novel strategy in AUD comorbidity with depression., This work was supported by grants awarded by Spanish Ministry of Economy PID2020- 114392RB-100, PDC2021-121566-100 and by Junta de Andalucía P20-00026-R and PI-0083-2019.

- [The full description of the dataset can be found at: https://www.uma.es/robotics-and-mechatronics/info/124594/sar-datasets/ ] - Collection of multimodal raw data captured from a manned all-terrain vehicle in the course of two realistic outdoor search and rescue (SAR) exercises for actual emergency responders conducted in Málaga (Spain) in 2018 and 2019: the UMA-SAR dataset. The sensor suite, applicable to unmanned ground vehicles (UGVs), consisted of overlapping visible light (RGB) and thermal infrared (TIR) forward-looking monocular cameras, a Velodyne HDL-32 three-dimensional (3D) lidar, as well as an inertial measurement unit (IMU) and two global positioning system (GPS) receivers as ground truth. Our mission was to collect a wide range of data from the SAR domain, including persons, vehicles, debris, and SAR activity on unstructured terrain. In particular, four data sequences were collected following closed-loop routes during the exercises, with a total path length of 5.2 km and a total time of 77 min. In addition, we provide three more sequences of the empty site for comparison purposes (an extra 4.9 km and 46 min). Furthermore, the data is offered both in human-readable format and as rosbag files, and two specific software tools are provided for extracting and adapting this dataset to the users’ preference. The review of previously published disaster robotics repositories indicates that this dataset can contribute to fill a gap regarding visual and thermal datasets and can serve as a research tool for cross-cutting areas such as multispectral image fusion, machine learning for scene understanding, person and object detection, and localization and mapping in unstructured environments., This work has been performed in the frame of the project “TRUST-ROB: Towards Resilient UGV and UAV Manipulator Teams for Robotic Search and Rescue Tasks,” funded by the Spanish Government (grant number RTI2018-093421-B-I00) and project UMA18-FEDERJA-090 funded by the Andalusian Regional Government (Junta de Andalucía)
