    Bullying affects thousands of teenagers worldwide and has devastating consequences. Various studies suggest that the personality of teenagers is a risk profile for bullying. The aim of this study was to analyse the relationship between the personality of teenagers aged 14 to 16 years from three education centres located in the province of Seville (Spain) and bullying in any of its victim or aggressor roles. A multi-centre cross-sectional observational descriptive study was conducted in three education centres in the province of Seville (Spain). The sample consisted of 93 students. In order to measure the two main variables, the Bull-S test was used for bullying, and the EPQ-J questionnaire was used for personality traits. A descriptive and correlation analysis was performed between variables. The results showed that 14% (n = 13) of the sample were detected as victims and another 14% (n = 13) were detected as aggressors. Statistically significant differences were found between neuroticism (p = 0.044; Phi = 0.615), sincerity (p = 0.016; V de Cramer = 0.474), and anti-social behaviour (p = 0.007; Phi = 0.620) with the variables victim/aggressor. Bullies are typically males who score high on neuroticism and anti-social behaviour, with a tendency towards social dissimulation

    Effects of intracoronary antithrombotics on ventricular function: A comparison of tenecteplase versus abciximab during primary percutaneous intervention in myocardial infarction

    Adjunctive medical therapy during primary percutaneous coronary intervention (PPCI) is based on anticoagulation and antiplatelet drugs. Additionally, the glycoprotein IIb/IIIa inhibitor (GPI) abciximab has been shown to reduce infarct size in some clinical trials [1]. However, the role of intracoronary fibrinolysis has not been well established during PPCI. We sought to explore the hypothesis that a locally administered fibrinolytic could be more effective in dissolving coronary thrombus at the macro and microvasculature than adding a third antiplatelet drug in patients already receiving double antiplatelet therapy, and therefore improve myocardial perfusion and left ventricular function

    Background: Simulation is a part of the day-to-day of the learning method in health sciences. The objective is to determine if the clinical simulation is useful for learning in the emergency setting, from the point of view of the nursing students. (2) Methods: A pre- and post-test exploratory study with an analytical and quasi-experimental design was used. The population is made up of nursing students from the Seville Red Cross Nursing Centre, who conducted a simulation exercise in the form of a drill for the care of multiple victims. A specific questionnaire was employed as a tool to analyse the dimensions of satisfaction, confidence and motivation, clinical experience, and decision making and technical abilities. (3) Results: There were favourable significant differences in the set of global responses, with p < 0.0001 for the “satisfaction” dimension and d = 1.25 for the “large” size of the effect, and p < 0.0069 for the “confidence and motivation” dimension and d = 0.58 for the “moderate–large” size of the effect. (4) Conclusions: The results are similar to those obtained in other studies in the scope of the 4 dimensions studied, thus coming to the conclusion that the perception of the nursing students on learning through clinical simulation is positive and favourable

    La seguridad alimentaria constituye, en principio, un impulso casi instintivo de los grupos humanos por asegurar su sobrevivencia frente a la escasez y se ha convertido en un asunto de seguridad nacional debido a la política económica del orden global que ha provocado desequilibrios internos. La  cuantificación de la inseguridad alimentaria en el ámbito nacional contribuiría de manera sustancial en la definición de los objetivos a corto, mediano y largo plazo  de los programas  orientados a combatir el hambre  y a la evaluación de su impacto. Así mismo, la identificación de los grupos en mayor  riesgo permitirá orientar los esfuerzos de dichos programas hacia los grupos más vulnerables. Por otro lado es evidente que los hogares necesitan generar ingresos suficientes y estables que les permitan satisfacer las necesidades básicas de manera sostenida, así como el fomento y rescate de la agricultura,  tanto para el autoconsumo como para la  generación de alimentos para  el resto de la población. Abstract Food security is, in principle, an almost instinctive impulse of human groups to ensure their survival against shortages and has become a matter of national security because of the economic policy of global order that has caused internal imbalances. Quantification of food insecurity at the national make a substantial contribution in defining the objectives in the short, medium and long term programs to combat hunger and assessing their impact. Furthermore, the identification of those most at risk will guide the efforts of such programs to the most vulnerable groups. On the other hand it is clear that households need to generate sufficient and stable income to enable them to meet basic needs steadily and rescue building and agriculture, both for consumption and for the generation of food for the rest of the population. Palabras clave: Seguridad Alimentaria, Inseguridad alimentaria, Pobreza, Hogar, Calidad de la dieta, disponibilidad de alimentos.

    Este estudio estimó la diversidad de avispas del género Blacus Nees (Braconidae, Blacinae) en dos ecosistemas forestales del noreste de Michoacán, en el Eje Neovolcánico Transversal: Parque Nacional Cerro de Garnica (PN C-Garnica) y Zona Protectora Forestal Los Azufres (ZPF Los Azufres). Se elaboró un mapa de cobertura vegetal con imágenes satelitales de estos ecosistemas forestales. La captura de especímenes se realizó mensualmente desde marzo 2008 hasta febrero 2010 con la ayuda de platos-trampa de color amarillo. Se capturó un total de 172 especímenes de 17 especies del género Blacus, de los cuales 84.3% provinieron del PN C-Garnica (13 especies) y 15.7% de la ZPF Los Azufres (10 especies). El porcentaje de similitud indicó una composición de especies diferente entre las dos áreas estudiadas (índice de Jaccard = 0.35). En el PN C-Garnica se capturaron significativamente más especímenes por mes que en la ZPF Los Azufres (12.1 ± 4.0 vs 2.3 ± 1.20). De acuerdo con el índice de Shannon-Wiener, la diversidad fue similar en ambas áreas estudiadas (2.1 vs 1.9). Los estimadores de riqueza Chao 2 y Jackknife 2 indicaron que en ambas áreas se capturó ~60% de las especies esperadas. Se concluye que el PN C-Garnica y la ZPF Los Azufres mantienen una alta diversidad de especies de Blacus. Las mayores abundancias, así como la mayor riqueza de especies se encontraron en el PN C-Garnica, la cual es una zona con mayor grado de perturbación.In this study, the diversity of wasps of the Blacus Nees (Braconidae, Blacinae) genus were estimated in two forest ecosystems in the northeastern part of Michoacán, in the Trans-Mexican Volcanic Belt: Cerro de Garnica National Park (C-Garnica NP) and Los Azufres Protected Forest Area (Los Azufres PFA). A vegetation cover map based on satellite images of these forest ecosystems was prepared. The specimens collecting was performed monthly from March 2008 until February 2010 with the help of yellow pan traps. A total of 172 specimens of 17 species of the genus Blacus were collected, of which 84.3% were from C-Garnica NP (13 species) and 15.7% from Los Azufres PFA (10 species). Percentage of similarity (Jaccard´s index = 0.35) was relatively low, indicating a different composition between both forest ecosystems. Significantly more specimens were monthly captured in C-Garnica NP than in Los Azufres PFA (12.1 ± 4.0 vs 2.3 ± 1.20). According to the Shannon-Wiener index, the diversity was similar in both studied areas (2.1 vs 1.9). Chao 2 and Jackknife 2 estimators indicated that ~60% of the expected species were captured in both areas. One concludes that C-Garnica NP and Los Azufres PFA maintain a high species diversity of Blacus. The greatest abundance, as well as the greatest species richness were found in the C-Garnica NP, which is an area with a higher degree of disturbance

    Effect of Different Cytokinins on Shoot Outgrowth and Bioactive Compounds Profile of Lemograss Essential Oil

    Lemongrass (Cymbopogon citratus) essential oil (EO) is a major source of bioactive compounds (BC) with anticancer activity such as α-citral, limonene, geraniol, geranyl acetate, and β-caryophyllene. Comparative studies about cytokinin effects on BC profiles in lemongrass are missing. Here, we evaluated four cytokinins (2iP, tZ, BAP, and KIN) in two different osmotic media, MS-N (3% sucrose, 3 g L−1 Gelrite™) and MS-S (5% sucrose, 5 g L−1 Gelrite™). It results in a higher multiplication rate in BAP containing medium compared to tZ, KIN, and 2iP (p ≤ 0.05). While shoots grown on MS-N/BAP, tZ, and KIN exhibited a highly branching morphology, MS-N/2iP produced a less branching architecture. BC profile analysis of established plants in pots revealed that their maxima production depends on the in vitro shoot growth conditions: i.e., highest content (80%) of α-citral in plants that were cultured in MS-S/BAP (p ≤ 0.05), limonene (41%) in MS-N/2iP, or geranyl acetate (25.79%) in MS-S/2iP. These results indicate that it is possible to increase or address the production of BC in lemongrass by manipulating the cytokinin type and osmotic pressure in culture media. The culture protocol described here is currently successfully applied for somatic embryogenesis induction and genetic transformation in lemongrass

    Purpose This study presents a treatment planning system for intraoperative low-energy photon radiotherapy based on photogrammetry from real images of the surgical site taken in the operating room. Material and methods The study population comprised 15 patients with soft-tissue sarcoma. The system obtains the images of the area to be irradiated with a smartphone or tablet, so that the absorbed doses in the tissue can be calculated from the reconstruction without the need for computed tomography. The system was commissioned using 3D printing of the reconstructions of the tumor beds. The absorbed doses at various points were verified using radiochromic films that were suitably calibrated for the corresponding energy and beam quality. Results The average reconstruction time of the 3D model from the video sequence in the 15 patients was 229,6±7,0 s. The entire procedure, including video capture, reconstruction, planning, and dose calculation was 520,6±39,9 s. Absorbed doses were measured on the 3D printed model with radiochromic film, the differences between these measurements and those calculated by the treatment planning system were 1.4% at the applicator surface, 2.6% at 1 cm, 3.9% at 2 cm and 6.2% at 3 cm. Conclusions The study shows a photogrammetry-based low-energy photon IORT planning system, capable of obtaining real-time images inside the operating room, immediately after removal of the tumor and immediately before irradiation. The system was commissioned with radiochromic films measurements in 3D-printed model
