Dos nuevas especies de los grupos Drosophila flavopilosa y Drosophila morelia (Diptera: Drosophilidae) en los Andes Orientales del Ecuador

One species in the Drosophila flavopilosa species group and another in the Drosophila morelia species group (Diptera: Drosophilidae) are described and illustrated. The larvae of the flies in these groups develop exclusively in flowers and, usually, are rarely collected from rotten plant parts. However, in this case, these new species were not collected from flowers but were captured with fermented banana and yeast. It indicates that this species may be attracted to the odors of yeast fermentation and not only solanaceous flowers. The specimens were collected at 3362 m above sea level. There are four species of the Drosophila flavopilosa species group and one species of the Drosophila morelia species group previously described from Ecuador. The new species are: Drosophila pseudokorefae sp. nov. in the Drosophila flavopilosa species group and Drosophila pseudomorelia sp. nov. in the Drosophila morelia species group.Se describen e ilustran una especie del grupo Drosophila flavopilosa y otra del grupo Drosophila Morelia (Diptera: Drosophilidae). Las larvas de las moscas de estos grupos se desarrollan exclusivamente en flores y raramente se recolectan de partes de plantas en putrefacción. Sin embargo, en este caso, estas nuevas especies no se recolectaron de flores, sino que se capturaron con trozos de plátano fermentado y levadura. Lo cual, indica que esta especie puede ser atraída por los olores de la fermentación de levadura y no solo por las flores de solanáceas. Los especímenes fueron recolectados a 3362 m sobre el nivel del mar. Existen cuatro especies del grupo Drosophila flavopilosa y una especie del grupo Drosophila morelia previamente descrita en Ecuador. Las nuevas especies son: Drosophila pseudokorefae sp. nov. en el grupo Drosophila flavopilosa y Drosophila pseudomorelia sp. nov. en el grupo Drosophila morelia

Diversidad del género Drosophila (Diptera, Drosophilidae) en la quebrada de Cruz Loma, Pichincha, Ecuador

The Cruz Loma gorge on the eastern slope of the Pichincha volcano in the province of Pichincha , was sampled during 2008 and early 2009, in order to determine the composition of the genus Drosophila. Thirteen collection points were determined. Traps with banana and yeast were used. Samples were taken from 3 100 to 4 000 m altitude. Ecosystems sampled were the páramo (3 500-4 100 m) covered by the genera Calamagrostis and Festuca and subpáramo (3 000-3 500 m) composed mainly of shrub forest. A total of 713 individuals of different species of Drosophila were captured. No specimens were collected over 3 850 m. Most individuals and species were recorded at 3 100 m (12 species). The months with the larger amounts of captured flies were July (239 specimens) and October (236 specimens). October was the month where the greatest number of species (14) were captured. Most abundant species were Drosophila rucux, (193 individuals captured throughout the year, from 3 100 up to 3 775 m), and Drosophila ecuatoriana (129 individuals captured from 3 100 up to 3 550 m altitude). Also, Drosophila hyalipennis Duda (1927) was also found for the first time in Ecuador at 3 325-3 400 m.La quebrada de Cruz Loma, situada en el lado oriental del volcán Pichincha, provincia de Pichincha, fue muestreada durante el año 2008 y comienzos del 2009 con la finalidad de poder determinar la composición de las especies del género Drosophila. Se fijaron 13 puntos de colecta, y se utilizaron trampas de banana-levadura. Los muestreos se realizaron desde los 3 100 hasta 4 000 m de altitud. Los ecosistemas muestreados fueron el páramo propiamente dicho (3 500–4 100 m) cubierto por los géneros Calamagrostis y Festuca y el subpáramo (3 000–3 500 m) compuesto en su mayor parte por vegetación arbustiva. Un total de 713 individuos de diferentes especies del género Drosophila fueron capturados. No se recolectaron especímenes sobre los 3 850 m.

The video guides and social tagging with the methodology of video annotation

Producto del PIE Video guías docentesTeaching guides are mandatory for quality agencies to evaluate teaching programmes, just as institutions require teachers to comply with them. This teaching resource has been seen as a very effective tool for the information and orientation of students in university programmes. However, the reality may turn out to be different, as the current practices with these guides are often not the desirable ones, as they are not used, read and studied by students with the level of depth that teachers wish, and in some cases they may be a mere formality for students, thus losing all their potential and meaning. The communication we present aims to present the results of a teaching innovation project to break this problem by producing video guides as digital resources that are more motivating for students. In addition, to design and experiment with a new methodology for its application and analysis of these resources in teaching programmes of any kind (face-to-face, blended and online programmes) by means of multimedia annotations. In this work we present the objectives, methodologies and resources proposed in this project, as the main conclusions we have reached as it has been to check a greater participation in the understanding of the programmes by the students, as a more active and motivating methodology to work with these resources in the classroom for an online modalityPIE.

Biocompatibility and corrosion protection behaviour of hydroxyapatite sol-gel-derived coatings on Ti6Al4V alloy

-2,5-diphenyl tetrazolium bromide (MTT) and Alamar blue cell viability assays were used to study the biocompatibility. Finally, the corrosion behaviour of HAp-coatings/Ti6Al4V system was researched by means of Electrochemical Impedance Spectroscopy (EIS). The obtained results showed that the prepared powders were nanocrystalline HAp with little deviations from that present in the human bone. All the prepared HAp coatings deposited on Ti6Al4V showed well-behaved biocompatibility, good bioactivity and corrosion protection properties.The authors would like to acknowledge financial support from the Ministry of Economy and Competitiveness of Spain (MAT2012-30854 and MAT2015-65445-C2-1-R Projects)

The effect of ionizing radiation on robotic trajectory movement and electronic components

peer reviewedRobotics applications are greatly needed in hazardous locations, e.g., fusion and fission reactors, where robots must perform delicate and complex tasks under ionizing radiation conditions. The drawback is that some robotic parts, such as active electronics, are susceptible to radiation. It can lead to unexpected failures and early termination of the robotic operation. This paper analyses the ionizing radiation effect from 0.09 to 1.5 Gy/s in robotic components (microcontrollers, servo motors and temperature sensors). The first experiment compares the performance of various microcontroller types and their actuators and sensors, where different mitigation strategies are applied, such as using Radiation-Hardened (Rad-Hard) microcontrollers or shielding. The second and third experiments analyze the performance of a 3-Degrees of Freedom (DoF) robotic arm, evaluating its componentsʼ responses and trajectory. This study enhances our understanding and expands our knowledge regarding radiationʼs impact on robotic arms and components, which is useful for defining the best strategies for extending the robotsʼ operational lifespan, especially when performing maintenance or inspection tasks in radiation environments

A Randomized Trial to Evaluate the Impact of Exercise-Based Cardiac Rehabilitation for the Prevention of Chemotherapy-Induced Cardiotoxicity in Patients With Breast Cancer: ONCORE Study Protocol

[Abstract] Background. Anthracyclines and monoclonal antibodies against human epidermal growth factor receptor-2 (HER2) are frequently used to treat breast cancer but they are associated with risk of developing cardiotoxicity. Implementation of cardioprotective strategies as part of breast cancer treatment are needed. To date, a limited number of studies have examined the effectiveness of cardiac rehabilitation programs or exercise programs in the prevention of cardiotoxicity through an integral assessment of cardiac function. The ONCORE study proposes an exercise-based cardiac rehabilitation program as a non-pharmacological tool for the management of chemotherapy-induced cardiotoxicity. Methods. The study protocol describes a prospective, randomized controlled trial aimed to determine whether an intervention through an exercise-based CR program can effectively prevent cardiotoxicity induced by anthracyclines and/or anti-HER2 antibodies in women with breast cancer. Three hundred and forty women with breast cancer at early stages scheduled to receive cardiotoxic chemotherapy will be randomly assigned (1:1) to participation in an exercise-based CR program (intervention group) or to usual care and physical activity recommendation (control group). Primary outcomes include changes in left ventricular ejection fraction and global longitudinal strain as markers of cardiac dysfunction assessed by transthoracic echocardiography. Secondary outcomes comprise levels of cardiovascular biomarkers and cardiopulmonary function through peak oxygen uptake determination, physical performance and psychosocial status. Supervised exercise program-related outcomes including safety, adherence/compliance, expectations and physical exercise in- and out-of-hospital are studied as exploratory outcomes. Transthoracic echocardiography, clinical test and questionnaires will be performed at the beginning and two weeks after completion of chemotherapy. Discussion. The growing incidence of breast cancer and the risk of cardiotoxicity derived from cancer treatments demand adjuvant cardioprotective strategies. The proposed study may determine if an exercise-based CR program is effective in minimizing chemotherapy-induced cardiotoxicity in this population of women with early-stage breast cancer. The proposed research question is concrete, with relevant clinical implications, transferable to clinical practice and achievable with low risk.Instituto de Salud Carlos III; PI17/0168

Thirty-Second Sit-To-Stand Test as an Alternative for Estimating Peak Oxygen Uptake and 6-Min Walking Distance in Women With Breast Cancer: A Cross-Sectional Study

[Abstract] Purpose: To determine whether the 30-s sit-to-stand (30STS) test can be a valid tool for estimating and stratifying peak oxygen uptake (VO2peak) and 6-min walking distance (6MWD) in women with breast cancer. Methods: This cross-sectional study uses data from the ONCORE randomized controlled trial, including 120 women aged 18-70 years with early-stage breast cancer under treatment with anthracycline and/or anti-HER2 antibodies. Participant characteristics were collected at baseline and pooled data from functional assessment (30STS test, relative and absolute VO2peak, and 6MWD) were collected at baseline and post-intervention (comprehensive cardio-oncology rehabilitation program vs. usual care). Bivariate correlations and multivariate linear regression analyses were performed to study the relationship between functional test variables. Results: The number of repetitions in the 30STS test showed (i) a moderate correlation with relative VO2peak (ml/kg/min) (r = 0.419; p < 0.001; n = 126), (ii) a weak correlation with absolute VO2peak (ml/min) (r = 0.241; p = 0.008; n = 120), and (iii) a moderate correlation with the 6MWD (r = 0.440; p < 0.001; n = 85). The ONCORE equations obtained from the multivariate regression models allowed the estimation of VO2peak and 6MWD (r2 = 0.390; r2 = 0.261, respectively) based on the 30STS test, and its stratification into tertiles (low, moderate, and high). Conclusion: The 30STS test was found to be a useful tool to estimate VO2peak and/or 6MWD in women with early-stage breast cancer. Its use may facilitate the assessment and stratification of functional capacity in this population for the implementation of therapeutic exercise programs if cardiopulmonary exercise testing (CPET) or 6MWT are not available.Open Access funding provided thanks to the CRUE-CSIC agreement with Springer Nature.
