Sensitisation to Act 2d in patientsallergic to Alternaria alternanta: an epiphenomenom without clinical significance?

In the last few years, the introduction of microarrays in the diagnosis of type I allergy is allowing the clinicians to have a much more accurate picture of their allergenic profile. However, the simultaneous measurement of specific IgE to multiple molecules can show unexpected sensitisations, without knowing their clinical relevance. For instance, we have been observing a high prevalence (74%) of sensitisation to Act d 2 (the thaumatin of kiwifruit) in patients sensitised to Alt a 1 (major allergen of Alternaria alternata) with a confirmed allergy to this mould. The aim of the present study was to clarify if there was any clinical relevance in this finding.

Cálculo de la atracción gravimétrica inducida por el Pabellón de Gravimetría del Centro de Desarrollos Tecnológicos de Yebes (Instituto Geográfico Nacional).

En el presente Trabajo Fin de Grado se modeliza la estructura del Pabellón de Gravimetría del Centro Astronómico de Yebes para así poder determinar su influencia sobre los valores de gravedad observados en el interior del Pabellón. El Pabellón de Gravimetría dispone en su interior de una sala dónde se realizan medidas de gravedad sobre siete pilares de hormigón situados a nivel del suelo. Para poder modelizar la sala de medida se ha realizado un levantamiento topográfico con las especificaciones técnicas de una escala 1:100. Tras la realización del levantamiento se han determinado las coordenadas geográficas del centro de los pilares de medida mediante el cálculo de una radiación, pues es necesario conocer éste dato al realizar medidas relativas de gravedad. Para el cálculo de la influencia que genera la estructura del Pabellón sobre las medidas de gravedad observadas en su interior se han creado una serie de programas en lenguaje Java empleando la fórmula de la atracción gravitatoria que genera un prisma (Nagy, 1969). Una vez se han llevado a cabo las observaciones y los cálculos necesarios se concluye que la influencia de la estructura sobre las medidas de la gravedad observadas en el interior del Pabellón no es de gran magnitud. No obstante esnecesario conocerla y así poder corregir los valores observados. Asimismo, se determina cierta desorientación de los pilares de medida con respecto al norte geográfico. El presente Trabajo Fin de Grado permitirá, entre otros, que el Centro de Desarrollos Tecnológicos de Yebes participe en proyectos de carácter internacional. Abstract: In the current Bachelor Thesis, the structure of the Pavellón de Gravimetría del Centro Astronómico de Yebes is moulded in order to determine its influence on the observed values of gravity inside the Pavilion. The Pabellón de Gravimetría holds in its interior a room where gravity measures are made on seven concrete pillars located on the ground level. In order to be able to mould the room, a topographical survey measurement was made on a 1:100 scale. After concluding the topographical survey measurement the geographical coordinates of the centre of the measurement pillars were determined, due to the necessity to know this data when making relative gravity measures. To calculate the influence that the pavilion structure has on the observed gravity measures in its interior generates, a series of programs in Java language have been created using the formula of the gravitational attraction that generates a prism (Nagy, 1969). Once the observations and the necessary calculations have been carried out, it is concluded that the influences of the structure of the Pavilion on the observed gravity measures inside it are not of a considerable magnitude. Despite that, it is necessary to know this to be able to correct the observed values. Also, certain disorientations of the pillars of measurement with respect to the geographical north is determined. The current Bachelor Thesis will allow, among others, the Centre of Technological Developments of Yebes to get involved in projects of international nature.

Occurrence of moulds associated with ovine raw milk and cheeses of the Spanish region of Castilla La Mancha

The distribution of mould species was examined at several points of the processing chain in a Manchego cheese plant and associated dairy farms. Geotrichum and Fusarium were the most frequent genera isolated in milk samples as well as in 1-month ripened cheeses, evidencing a direct transfer from raw milk. Conversely, the mycobiota of long-ripened cheeses consisted mainly of Penicillium species, which gained entry to the cheese through the air of ripening rooms. This study contributes to the understanding of the dynamics of fungal populations in semihard and hard cheeses, highlighting that airborne transfer from the stables could have a direct impact on their quality.
