Análisis de patrones de movilidad del transporte turístico motorizado privado en el Centro Histórico de Cuenca -Ecuador

El presente trabajo, tuvo un enfoque geográfico exploratorio longitudinal, aborda los patrones de movilidad del transporte turístico motorizado privado en el Centro Histórico de Cuenca. Mediante mapas y entrevistas semiestructuradas aplicadas a los diferentes actores, además se identificaron los atractores de las rutas turísticas en servicio, y se evaluó la incidencia del transporte turístico dentro de la zona. El transporte turístico en taxis y busetas no está regulado. Las rutas Norte y Sur son las únicas autorizadas por la Dirección de Gestión de Movilidad para operar con buses panorámicos. Las empresas VANSERVICE y COTRATUDOSSA operan con tres y dos buses, respectivamente, que circulan a 10 km/h. El horario inicia a las 09h30, termina a las 19h00 y alcanza el 70% de ocupación entre semana y el 100% en fines de semana. El tiempo de viaje es adecuado para los turistas nacionales, y puede extenderse para los extranjeros. Adicionalmente los turistas no perciben las condiciones de tráfico como un problema. Según los gerentes, conductores y guías de turismo, las entidades de planificación y control deben asegurar el adecuado desarrollo de la actividad, definir variantes de la ruta ante incidentes durante la operación, evitar la interacción con otros modos, mantener los corredores y ampliar la oferta. Finalmente, el transporte turístico contribuye a la congestión vehicular dentro del centro histórico, afecta la fluidez del tráfico, disminuye la capacidad vial durante el embarque/desembarque de pasajeros, interviene en conflictos con otros modos por el irrespeto a los servicios asignados para los buses turísticos.

The Role of Bmp- and Fgf Signaling Modulating Mouse Proepicardium Cell Fate

Bmp and Fgf signaling are widely involved in multiple aspects of embryonic development. More recently non coding RNAs, such as microRNAs have also been reported to play essential roles during embryonic development. We have previously demonstrated that microRNAs, i.e., miR-130, play an essential role modulating Bmp and Fgf signaling during early stages of cardiomyogenesis. More recently, we have also demonstrated that microRNAs are capable of modulating cell fate decision during proepicardial/septum transversum (PE/ST) development, since over-expression of miR-23 blocked while miR- 125, miR-146, miR-223 and miR-195 enhanced PE/ST-derived cardiomyogenesis, respectively. Importantly, regulation of these microRNAs is distinct modulated by Bmp2 and Fgf2 administration in chicken. In this study, we aim to dissect the functional role of Bmp and Fgf signaling during mouse PE/ST development, their implication regulating post-transcriptional modulators such as microRNAs and their impact on lineage determination. Mouse PE/ST explants and epicardial/endocardial cell cultures were distinctly administrated Bmp and Fgf family members. qPCR analyses of distinct microRNAs, cardiomyogenic, fibrogenic differentiation markers as well as key elements directly epithelial to mesenchymal transition were evaluated. Our data demonstrate that neither Bmp2/Bmp4 nor Fgf2/Fgf8 signaling is capable of inducing cardiomyogenesis, fibrogenesis or inducing EMT in mouse PE/ST explants, yet deregulation of several microRNAs is observed, in contrast to previous findings in chicken PE/ST. RNAseq analyses in mouse PE/ST and embryonic epicardium identified novel Bmp and Fgf family members that might be involved in such cell fate differences, however, their implication on EMT induction and cardiomyogenic and/or fibrogenic differentiation is limited. Thus our data support the notion of species-specific differences regulating PE/ST cardiomyogenic lineage commitment

Short-Interval, Severe Wildfires Alter Saproxylic Beetle Diversity in Andean Araucaria Forests in Northwest Chilean Patagonia

The occurrence of short-interval, severe wildfires are increasing drastically at a global scale, and appear as a novel phenomenon in areas where fire historically returns in large time lapses. In forest ecosystems, these events induce drastic changes in population dynamics, which could dramatically impact species diversity. Here, we studied the effect on diversity of recent short-interval, severe wildfires (SISF), which occurred in rapid succession in the summers of 2002 and 2015 in Chilean Northern Patagonian Araucaria–Nothofagus forests. We analyzed the diversity of deadwood-dependent (i.e., saproxylic) and fire-sensitive beetles as biological indicators across four conditions: 2002-burned areas, 2015-burned areas, SISF areas (i.e., burned in 2002 and again in 2015), and unburned areas. Saproxylic beetles were collected using window traps in 2017 to 2019 summer seasons. To investigate the mechanisms underpinning the fire-related disturbance of the assemblage, we evaluated the effects of post-fire habitat quality (e.g., dead wood decomposition) and quantity (e.g., burned dead wood volume and tree density) on the abundances and species richness of the entire assemblage and also multiple trophic groups. Compared with the unburned condition, SISF drastically reduced species richness, evenness, and Shannon’s diversity and altered the composition of the saproxylic beetle assemblages. The between-condition variation in composition was accounted for by a species replacement (turnover) between SISF and 2015-burned areas, but both species replacement and extinction (nestedness) between SISF and unburned areas. Dead wood decomposition and tree density were the variables with the strongest effects on the abundance and species richness of the entire saproxylic beetle assemblage and most trophic groups. These results suggest that SISF, through degraded habitat quality (dead wood decomposition) and quantity (arboreal density), have detrimental impacts on diversity and population dynamics of saproxylic beetle assemblages. Therefore, habitat loss is a central mechanism underpinning fire-related biodiversity loss in these forest ecosystems.F.T.

Transplantation or Transference of Cultured Cells as a Treatment for Spinal Cord Injury

Spinal cord injury (SCI) involves damage to the spinal cord causing both structural and functional changes, which can lead to temporary or permanent alterations. Even though there have been many advances in its treatment, the results of clinical trials suggest that the current therapies are not sufficiently effective. Recently, there has been a lot of interest in regulating this harmful environment by transplanting cultured cells and boosting their antiinflammatory cytokines and growth factors production. Several types of cells have been studied for SCI therapy including, Schwann cells (SC’s), olfactory ensheathing cells (OECs), choroid plexus epithelial cells (CPECs), and immune cells (ICs) (lymphocytes, dendritic cells and alternative macrophage and microglia phenotypes). These treatments have shown to be promising and in this chapter, we will review the general aspects of transplanting these cells for SCI therapy as well as the neuroprotective and regenerative responses that different types of cells have reached in different SCI models. The mesenchymal stem cells (MSC) are one of the most well studied cell types; however, they were not included in this section because they will be reviewed in another chapter of this book

Transcriptome Analysis Identifies Novel Mechanisms Associated with the Antitumor Effect of Chitosan‐Stabilized Selenium Nanoparticles.

Selenium nanoparticles (SeNPs) have been receiving special attention in recent years due to their antioxidant capacity and antitumor properties. However, the mechanisms associated with these properties remain to be elucidated. For this reason, a global transcriptome analysis has been designed in this work and it was carried out using human hepatocarcinoma cells and chitosan‐ stabilized SeNPs (Ch‐SeNPs) to identify new targets and pathways related to the antitumor mechanisms associated with Ch‐SeNPs. The results obtained confirm the alteration of the cell cycle and the effect of Ch‐SeNPs on different tumor suppressors and other molecules involved in key mechanisms related to cancer progression. Furthermore, we demonstrated the antioxidant properties of these nanoparticles and their capacity to induce senescence, which was further confirmed through the measurement of β‐galactosidase activity

Motives for exercising among young adults with a moderately positive body image

Background: People engage in exercise and sports due to several reasons, depending on factors such as age, sex and health or fitness status. These motives include enhancing health and fitness status, improving appearance and body image or enjoying in leisure time. Aims & Methods: Grounded in Self-Determination Theory (SDT), this study explored motives for exercising in healthy men and women 18 to 40 years old who were regular exercisers and held a moderately positive body image. They voluntarily completed an online survey on their exercise practice, body image and motives for exercising. Results: Contrary to previous SDT-based empirical findings, appearance improvement emerged as an important motive for exercising, and it was more frequently mentioned than health&fun-related motives by the whole sample and by subsamples of men and women and younger young and older young adults. Conclusions: Given that appearance management-related motives may have both positive and undesired outcomes on exercise behaviour and personal well-being, they should be carefully reviewed with women and men in their young adulthood who are exercise intenders, beginners or regular exercisers

La actuación profesional de la Psicología en las residencias de personas mayores.

The COPCyL Aging Psychology Working Group believes is important to have a psychology professional within the interdisciplinary teams of the residential centers of elderly people in order to offer comprehensive care and quality. In order to make known what the role of this professional in the residences is presented a plan of action. It discusses their interventions by focusing, according to who they are directed, in the resident (cognitive, emotional and behavioral), in the family and in the institution. We think that in this way their performance and the need for their incorporation to work teams is justified. As a future line of work we introduce an instrument to train relational frames in older (MAREMA).El grupo de trabajo de Psicología del Envejecimiento del COPCyL considera importante contar con un profesional de la Psicología dentro de los equipos interdisciplinares de los centros residenciales de personas mayores para poder ofrecer una atención integral y de calidad. Con el objetivo de dar a conocer cuál es el papel de este profesional en las residencias se presenta un plan de actuación de las intervenciones centrándose, según a quiénes están dirigidas, en el/la residente (a nivel cognitivo, emocional y conductual), en la familia y en la institución. Pensamos que de esta manera queda justificada su actuación y la necesidad de su incorporación a los equipos de trabajo. Como línea de trabajo futura introducimos un instrumento para entrenar Marcos Relacionales en Mayores (MAREMA)
