Fish mitigate trophic depletion in marine cave ecosystems.

Dark marine habitats are often characterized by a food-limited condition. Peculiar dark habitats include marine caves, characterized by the absence of light and limited water flow, which lead to reduced fluxes of organic matter for cave-dwelling organisms. We investigated whether the most abundant and common cave-dwelling fish Apogon imberbis has the potential to play the role of trophic vector in Mediterranean marine caves. We first analysed stomach contents to check whether repletion changes according to a nycthemeral cycle. We then identified the prey items, to see whether they belong to species associated with cave habitats or not. Finally, we assessed whether A. imberbis moves outside marine caves at night to feed, by collecting visual census data on A. imberbis density both inside and outside caves, by day and by night. The stomach repletion of individuals sampled early in the morning was significantly higher than later in the day. Most prey were typical of habitats other than caves. A. imberbis was on average more abundant within caves during the day and outside during the night. Our study supports the hypothesis regarding the crucial trophic role of A. imberbis in connecting Mediterranean marine caves with external habitat

Desarrollo de un entorno integrado para un computador didáctico elemental, para la asignatura de Fundamentos de Informática del nuevo grado en Ingeniería de Tecnologías de Telecomunicación

El objetivo principal de este trabajo es la potenciación y mejora de la metodología docente en la asignatura de Fundamentos de Informática, asignatura obligatoria correspondiente al nuevo Grado en Ingeniería de Tecnologías de Telecomunicación de la Universidad de Granada. Para ello, se ha desarrollado un entorno integrado didáctico que engloba, en una sola aplicación, tanto el simulador como el ensamblador de un Computador Didáctico Elemental desarrollado en nuestro departamento, CODE-2, y que, además, incorpora un programa editor y un ensamblador en línea con el que el alumno puede visualizar directamente el código máquina generado por el código ensamblador que está escribiendo en tiempo real. De esta forma, conseguimos facilitar que los alumnos puedan adquirir los conocimientos necesarios para comprender el funcionamiento interno de un computador.Subvencionado parcialmente por el proyecto de Innovación Docente 10-22 de la Universidad de Granad

Prevalence of metabolic syndrome in Murcia Region, a southern European Mediterranean area with low cardiovascular risk and high obesity

<p>Abstract</p> <p>Background</p> <p>Metabolic syndrome (MS) is associated with subsequent appearance of diabetes and cardiovascular disease. As compared to other Spanish regions, Murcia (southern Spain) registers increased obesity as well as cardiovascular morbidity and mortality. The aim of this study was to assess the prevalence of MS and its components, awareness of obesity as a health risk and associated lifestyles.</p> <p>Methods</p> <p>A population-based, cross-sectional study was conducted in 2003, covering a sample of 1555 individuals 20 years and over. MS was defined according to the Revised National Cholesterol Education Program Adult Treatment Panel III (R-ATPIII), International Diabetes Federation (IDF) and Joint Interim Statement (JIS) criteria. Both low (94/80) and high (102/88) waist circumference (WC) thresholds were considered.</p> <p>Results</p> <p>Prevalence of MS was 27.2% (95%CI: 25.2-29.2), 32.2% (95%CI: 30.1-34.3) and 33.2% (95%CI: 31.2-35.3) according to the R-ATPIII, IDF and JIS94/80 respectively. It increased with age until reaching 52.6% (R-ATPIII) or 60.3% (JIS94/80) among persons aged 70 years and over, and was higher in persons with little or no formal education (51.7% R-ATPIII, 57.3% JIS94/80). The most common risk factors were hypertension (46.6%) and central obesity (40.7% and 66.1% according to high and low WC cut-off points respectively). Although most persons were aware that obesity increased health risks, regular exercise was very unusual (13.0% centrally obese, 27.2% non-centrally obese). Adherence to dietary recommendations was similar among centrally obese and non-centrally obese subjects.</p> <p>Conclusions</p> <p>Prevalence of MS is high in our population, is comparable to that found in northern Europe and varies with the definition used. Adherence to preventive recommendations and to adequate weight promotion is very low. In the absence of a specific treatment for MS, integrated intervention based on a sustained increase in physical activity and changes in diet should be reinforced.</p

Lichenological exploration of Algeria: historical overview and annotated bibliography, 1799-2013

yesDespite more than two centuries of almost uninterrupted surveys and studies of Algerian lichenology, the history and lichen diversity of Algeria are still poorly understood. During the preparation of a forthcoming checklist of Algerian lichens it was considered necessary to provide the present historical overview of lichenological exploration of the country from 1799 to 2013, supported by a reasonably comprehensive annotated bibliography of 171 titles

Epidemiological trends of HIV/HCV coinfection in Spain, 2015-2019

Altres ajuts: Spanish AIDS Research Network; European Funding for Regional Development (FEDER).Objectives: We assessed the prevalence of anti-hepatitis C virus (HCV) antibodies and active HCV infection (HCV-RNA-positive) in people living with HIV (PLWH) in Spain in 2019 and compared the results with those of four similar studies performed during 2015-2018. Methods: The study was performed in 41 centres. Sample size was estimated for an accuracy of 1%. Patients were selected by random sampling with proportional allocation. Results: The reference population comprised 41 973 PLWH, and the sample size was 1325. HCV serostatus was known in 1316 PLWH (99.3%), of whom 376 (28.6%) were HCV antibody (Ab)-positive (78.7% were prior injection drug users); 29 were HCV-RNA-positive (2.2%). Of the 29 HCV-RNA-positive PLWH, infection was chronic in 24, it was acute/recent in one, and it was of unknown duration in four. Cirrhosis was present in 71 (5.4%) PLWH overall, three (10.3%) HCV-RNA-positive patients and 68 (23.4%) of those who cleared HCV after anti-HCV therapy (p = 0.04). The prevalence of anti-HCV antibodies decreased steadily from 37.7% in 2015 to 28.6% in 2019 (p < 0.001); the prevalence of active HCV infection decreased from 22.1% in 2015 to 2.2% in 2019 (p < 0.001). Uptake of anti-HCV treatment increased from 53.9% in 2015 to 95.0% in 2019 (p < 0.001). Conclusions: In Spain, the prevalence of active HCV infection among PLWH at the end of 2019 was 2.2%, i.e. 90.0% lower than in 2015. Increased exposure to DAAs was probably the main reason for this sharp reduction. Despite the high coverage of treatment with direct-acting antiviral agents, HCV-related cirrhosis remains significant in this population

Estudio socioeducativo de las conductas disruptivas en la región de Murcia

Hacer un estudio descriptivo socioeducativo de las conductas disruptivas en EGB de la región de Murcia. Relacionar las conductas disruptivas de los alumnos de EGB con la instrucción paterna, profesión paterna, metodología didáctica, ciclos de la EGB y horas de clases. Conocer las conductas disruptivas más representativas en la EGB de la región de Murcia. 21 colegios. El número de profesores que contestaron al cuestionario fue de 253 y el número de alumnos observados 8915. Recogida de la información mediante observaciones de clase y un cuestionario elaborado 'ad hoc'. Observación en las clases. Cuestionario. Técnica análisis frecuencial. Análisis comparativo y relacional. Las conductas disruptivas de los alumnos de la EGB están relacionadas con la clase social. El ciclo de más conductas disruptivas es el Superior, seguido del Medio y finalmente el Inicial. No hay relación entre conducta disruptiva y hora de clase. Ordinariamente los alumnos presentan más de una conducta disruptiva. Las conductas que más distorsionan el clima de la clase son: charlatán, inquieto, distraido, no participativo. El promedio de alumnos con conductas disruptivas por clase es de 4'23 por ciento, que representan un 13 por ciento de niños con problemas de conductas. Las conductas disruptivas se dan menos en el ciclo Inicial y donde más en el Superior. Hay relación entre conducta disruptiva y clase social. En cuanto a la metodología didáctica no hemos podido sacar conclusiones concretas siendo objeto de otra investigación.MurciaES
