Transformation of Construction Cement to a Self-Healing Hybrid Binder
2019
A new biomimetic strategy to im prove the self-healing properties of Portland cement is presented that is based on the application of the biogenic inorganic polymer polyphosphate (polyP), which is used as a cement admixture. The data show that synthetic linear polyp, with an average chain length of 40, as well as natural long-chain polyP isolated from soil bacteria, has the ability to support self-healing of this construction material. Furthermore, polyP, used as a water-soluble Na-salt, is subject to Na+/Ca2+ exchange by the Ca2+ from the cement, resulting in the formation of a water-rich coacervate when added to the cement surface, especially to the surface of bacteria-containing cement/c…
A systematic review of human behaviour in and around floodwater
2020
Abstract Flooding can have a major impact on people's safety and livelihood. Understanding people's flood-related behaviours may assist in the development of more effective strategies aimed at lessening the impact of floods including mortality and morbidity. This systematic review examined peer-reviewed literature published from January-1989 to April-2019 on human behaviour in and around floodwater to identify behaviour patterns as well as protective and risk factors. We extracted three main themes from a thematic analysis of included studies (N = 54): activities and risk-taking behaviours (n = 24); loss reduction, knowledge, and warnings (n = 37); and diet and hygiene (n = 4). This review …
Automated Dental Identification with Lowest Cost Path-Based Teeth and Jaw Separation
2016
Abstract Teeth are some of the most resilient tissues of the human body. Because of their placement, teeth often yield intact indicators even when other metrics, such as finger prints and DNA, are missing. Forensics on dental identification is now mostly manual work which is time and resource intensive. Systems for automated human identification from dental X-ray images have the potential to greatly reduce the necessary efforts spent on dental identification, but it requires a system with high stability and accuracy so that the results can be trusted. This paper proposes a new system for automated dental X-ray identification. The scheme extracts tooth and dental work contours from the X-ray…
Análisis de los factores ligados al diagnóstico del trastorno por déficit de atención e hiperactividad en la infancia
2017
Resumen: Introducción: El trastorno por déficit de atención e hiperactividad (TDAH) es un trastorno neuropsiquiátrico de origen multifactorial. El objetivo de este estudio es determinar el porcentaje de pacientes que presentan TDAH del global de los enviados a la consulta por este motivo, y explorar los factores epidemiológicos y clínicos asociados al diagnóstico. Pacientes y métodos: Estudio retrospectivo analítico de una muestra de pacientes derivados a la consulta de neuropediatría por sospecha de TDAH, a la que se le aplican los criterios diagnósticos del DSM-IV. Se realiza un análisis de regresión logística para explorar los factores asociados al diagnóstico. Resultados: De los 280 pac…
Impacto de las recomendaciones sobre la vacunación del tétanos-difteria en el ámbito laboral
2017
Resumen Objetivo El objetivo de nuestro estudio es evaluar el impacto de las recomendaciones del Ministerio de Sanidad y Consumo en cuanto a la vacunacion en una mutua colaboradora con la Seguridad Social (FREMAP). Metodo Se trata de un estudio observacional retrospectivo de la vacunacion de tetanos-difteria (Td) en adultos, en FREMAP, entre enero de 2012 y diciembre de 2013. Resultados Se han registrado 126.101 accidentes susceptibles de vacunacion de Td, de los cuales han sido vacunados 11.468 (9%). No ha habido diferencias significativas en cuanto a si fueron accidentes incapacitantes o no, ni en cuanto a sexo. Se han encontrado diferencias significativas en el grupo de edad 46-55 anos, …
Consenso para el diagnóstico, tratamiento y seguimiento del paciente con distrofia muscular de Duchenne
2019
Resumen: Introducción: La distrofia muscular de Duchenne (DMD) es la miopatía más frecuente en niños, con una prevalencia mundial de aproximadamente 0,5 por cada 10.000 varones. Se caracteriza por una debilidad muscular progresiva al inicio de la infancia con aparición posterior de complicaciones musculoesqueléticas, respiratorias y cardíacas que ocasionan discapacidad, dependencia y muerte prematura. Actualmente su tratamiento se fundamenta en medidas sintomáticas multidisciplinares que han modificado favorablemente el curso de la enfermedad, por lo que resulta crucial establecer unas directrices claras y actualizadas que permitan tanto una detección temprana de la enfermedad como un adecu…
Documento de consenso de un grupo de expertos de la Sociedad Española de Arteriosclerosis (SEA) sobre el uso clínico de la resonancia magnética nucle…

Resumen La evaluacion y prevencion del riesgo cardiovascular (RCV) que persiste en los pacientes con dislipidemia a pesar del tratamiento y de haber alcanzado los objetivos especificos de la concentracion plasmatica de colesterol unido a lipoproteinas de baja densidad (c-LDL) es un reto clinico en la actualidad, y sugiere que los biomarcadores lipidicos convencionales resultan insuficientes para una evaluacion precisa del RCV. Mas alla de su contenido lipidico, existen otras caracteristicas propias de las particulas lipoproteicas que determinan su potencial aterogenico y su influencia en el RCV. Sin embargo, dichas caracteristicas adicionales no pueden ser analizadas por las tecnicas utiliz…
The montrachet study
2016
National audience; Summary The Montrachet Study (Maculopathy Optic Nerve nuTRition neurovAsCular and HEarT diseases) is a population‐based derived from the 3C Study performed in Dijon. In 2009–2011, 1153 participants from the 3 Cities Study, aged 75 years or more, had an initial eye examination. Apart from the old age of this population, the main interest is that information on cardiovascular and neurologic diseases and a large comprehensive database (blood samples, genetic testing, cognitive tests, MRI) were available. Our first results showed us that despite the high prevalence of self‐reported eye diseases in this elderly population, visual impairment was low and increased with age. Thes…
10-Year Journey Through Brain Gliomas: Case Report
2020
Abstract We present the case of a 28-year-old doctor who was diagnosed in 2009 with grade II oligodendroglioma. In the next 10 years he underwent 4 surgeries, passing in turn through 3 different types of cerebral gliomas: grade II oligodendroglioma, grade III oligoastrocytoma and IDH Wild-Type glioblastoma. In the spirit of the surgical resection limited by the preservation of the function, he was able to practice his medical profession until the last months of his life. Life expectancy at the time of diagnosis complied with all the statistical data. Although the etiology, pathophysiology and treatment of cerebral gliomas is still full of unknowns, knowing our limits we can provide a good q…
Biological and physical modification of carbonate system parameters along the salinity gradient in shallow hypersaline solar salterns in Trapani, Ita…
2017
Abstract We investigated changes in the chemical characteristics of evaporating seawater under the influence of microbial activity by conducting geochemical analyses of the brines and evaporite sediments collected from solar salterns in Trapani, Italy. The microbial activity had a substantial effect on the carbonate system parameters. Dissolved inorganic carbon (DIC) was substantially removed from the brine during the course of evaporation from the seawater to the point where calcium carbonate precipitates, with an accompanying decrease in its carbon isotopic composition (δ 13 C DIC ) to as low as −10.6‰. Although the removal of DIC was due to calcium carbonate precipitation, photosynthesis…
