Aussagefähigkeit der Abdomenübersichtsaufnahme in der Differenzierung der Rotavirus-negativen und Rotavirus-positiven nekrotisierenden Enterokolitis
1991
Clinical data and radiographic findings of 32 newborn suffering from necrotising enterocolitis were analysed [12 patients with rotavirus-positive necrotising enterocolitis (RV + NEC), 20 patients with rotavirus-negative necrotising enterocolitis (RV-NEC)]. The presence and degree of pneumatosis intestinalis, portal venous gas and pneumoperitoneum on abdominal radiographs were graded after Kosloske et al. according to "mild, moderate, and severe". Pneumatosis intestinalis occurred twice as often in the ascending colon in RV-NEC compared to RV + NEC, whereas the transverse colon was involved nearly as frequently as the descending colon in both groups. Portal venous gas was present in 10% of t…
Functional Adhesion of Pectin Biopolymers to the Lung Visceral Pleura
2021
Pleural injuries and the associated “air leak” are the most common complications after pulmonary surgery. Air leaks are the primary reason for prolonged chest tube use and increased hospital length of stay. Pectin, a plant-derived heteropolysaccharide, has been shown to be an air-tight sealant of pulmonary air leaks. Here, we investigate the morphologic and mechanical properties of pectin adhesion to the visceral pleural surface of the lung. After the application of high-methoxyl citrus pectin films to the murine lung, we used scanning electron microscopy to demonstrate intimate binding to the lung surface. To quantitatively assess pectin adhesion to the pleural surface, we used a custom ad…
Estudio experimental in vitro de la adhesión entre la cerámica de óxido de circonio y distintos cementos de resina compuesta.
2010
La creciente demanda de tratamientos dentales estéticos y el continuo avance de la investigación ha permitido que en la actualidad podamos recurrir a distintos materiales cerámicos según las necesidades de tratamiento requeridas. Dentro de estos materiales cerámicos encontramos la cerámica de óxido de circonio, la cual presenta numerosas ventajas en cuanto a opacidad, resistencia y biocompatibilidad, pero se desconoce su comportamiento a la hora de unirse a las resinas compuestas, utilizadas estas como material de cementado. OBJETIVOS: Evaluar la fuerza de adhesión entre el óxido de circonio y distintos cementos de resina compuesta mediante un ensayo de cizalla. Estudiar a microscopia elect…
Desarrollo de un método digital para la medición y predicción de tamaños dentarios: aplicaciones para determinar alteraciones en el índice de Bolton.
2004
El objetivo de la Tesis Doctoral era introducir y comparar un nuevo Método Digital que basándose en la digitalización de los modelos de estudio de escayola y un software de apoyo permitía calcular la medición de los tamaños mesiodistales de los dientes, longitudes de arcada, discrepancias osedodentarias e índices de Bolton, además de predecir los tamaños de los dientes no erupcionados en dentición mixta.Se seleccionaron 100 pares de modelos de estudio en dentición permanente, 30 correspondían a mujeres y 70 a hombres, con una edad decimal media de 14,8 años (rango 11,2-22,7 años).Procedimos a la medición de los tamaños mesiodistales de todos los dientes de cada uno de los pacientes, por los…
Estudio comparativo de las características de las arcadas dentarias entre tres grupos de edad: adolescentes, adultos jóvenes y adultos.
2009
Son varios los cambios tanto dimensionales como morfológicos que sufre la arcada dentaria con la edad, ocurriendo las mayores alteraciones en los periodos de crecimiento. Sin embargo, es conocido que estas alteraciones no cesan en el inicio de la edad adulta sino que continúan, aunque a un ritmo más lento. Es importante tener esto en consideración a la hora de elaborar el plan de tratamiento ortodóncico, pues nos podrá dar información acerca de la estabilidad y de la recidiva del tratamiento. El objetivo del presente trabajo fue describir y comparar las dimensiones dentarias y de arcada, bien como la discrepancia oseodentaria entre cada sexo y grupo de edad; analizar la variabilidad para ca…
Recognition and alignment of variables from UV–vis chromatograms and application to industrial enzyme digests classification
2017
Abstract In the last years, industrial applications of chemometrics have largely increased due to their capacity to extract important information from complex records as chromatograms or spectra data. The use of chemometric methods also can avoid the use of detectors of elevated cost. In this work, a procedure to recognize the relevant chemical information contained in complex UV–vis chromatograms, after a trypsin digestion, to identify the three enzyme main classes (proteases, amylases and cellulases) commonly employed in the cleaning industry, has been developed. In order to recognize the chromatogram peaks, six indices of peak identity or identifiers were defined. A program written in MA…
Effects of Vermicompost, Compost and Digestate as Commercial Alternative Peat-Based Substrates on Qualitative Parameters of Salvia officinalis
2021
Peat is a common substrate used for the cultivation of potted plants. However, the use of peat in horticulture has recently been questioned from an environmental standpoint, since it is a non-renewable resource and plays a major role in atmospheric CO2 sequestration. The aim of this work was to assess the potentialities of substrates obtained from vermicompost, compost and anaerobic digestion processes to partially substitute peat for sage (Salvia officinalis L.) cultivation. Therefore, we planned an experiment to assess the effect of these substrates on essential oil (EO) yield and composition, as well as on leaf nutrients concentration of sage plants. The three substrates were mixed with …
Water-Dependent Blending of Pectin Films: The Mechanics of Conjoined Biopolymers
2020
Biodegradable pectin polymers have been recommended for a variety of biomedical applications, ranging from the delivery of oral drugs to the repair of injured visceral organs. A promising approach to regulate pectin biostability is the blending of pectin films. To investigate the development of conjoined films, we examined the physical properties of high-methoxyl pectin polymer-polymer (homopolymer) interactions at the adhesive interface. Pectin polymers were tested in glass phase (10&ndash
Hepatitis C virus prevalence and level of intervention required to achieve the WHO targets for elimination in the European Union by 2030: a modelling…
2017
Background Hepatitis C virus (HCV) is a leading cause of liver-related morbidity and mortality worldwide. In the European Union (EU), treatment and cure of HCV with direct-acting antiviral therapies began in 2014. WHO targets are to achieve a 65% reduction in liver-related deaths, a 90% reduction of new viral hepatitis infections, and 90% of patients with viral hepatitis infections being diagnosed by 2030. This study assessed the prevalence of HCV in the EU and the level of intervention required to achieve WHO targets for HCV elimination. Methods We populated country Markov models for the 28 EU countries through a literature search of PubMed and Embase between Jan 1, 2000, and March 31, 201…
Register and clinical follow-up of patients with Peutz-Jeghers syndrome in Valencia
2020
Introduction and aims: Peutz-Jeghers syndrome is a rare autosomal dominant inherited disease caused by a germline mutation of the STK11/LKB1 gene, located on chromosome 19p13.3. It is characterized by mucocutaneous hyperpigmentation, hamartomatous polyposis, and predisposition to cancer. The aim of the present study was to identify and register patients with Peutz-Jeghers syndrome, describe the disease, and estimate its prevalence in Valencia (Spain). Materials and methods: A print-out of the clinical histories from 10 hospitals was obtained utilizing the ICD-9 code 759.6 from the Minimum Basic Data Set of Hospital Admissions of the Spanish Ministry of Health and Consumer Affairs. Results: …
