Irrigation performance and gross water productivity in furrow-irrigated ornamental tree production

In the ornamental plant production region of Girona (Spain), which is one of the largest of its kind in southern Europe, most of the surface is irrigated using wide blocked-end furrows. The objectives of this paper were: (1) to evaluate the irrigation scheduling methods used by ornamental plant producers; (2) to analyse different scenarios in order to assess how they affect irrigation performance; (3) to evaluate the risk of deep percolation; and (4) to calculate gross water productivity. A two-year study in a representative commercial field, planted with Prunus cerasifera ‘Nigra’, was carried out. The irrigation dose applied by the farmers was slightly smaller than the required water dose estimated by the use of two different methods: the first based on soil water content, and the second based on evapotranspiration. Distribution uniformity and application efficiency were high, with mean values above 87%. Soil water content measurements revealed that even at the end of the furrow, where the infiltrated water depth was greatest, more than 90% of the infiltrated water was retained in the shallowest 40 cm of the soil; accordingly, the risk of water loss due to deep percolation was minimal. Gross water productivity for ornamental tree production was € 11.70 m–3, approximately 20 times higher than that obtained with maize in the same region

Role of alpha 2,3-sialyltransferases ST3Gal III and ST3Gal IV in pancreatic ductal adenocarcinoma

Este trabajo demuestra que los genes que codifican para los enzimas beta-galactosido alfa-2,3-sialiltransferasa 3 (ST3Gal III), y en menor medida beta-galactosido alfa-2,3-sialiltransferasa 4 (ST3Gal IV), están directamente implicados en etapas clave de la progresión tumoral como la adhesión, la migración y la formación de metástasis en las líneas de adenocarcinoma pancreático humano Capan-1 y MDAPanc-28. También, que las Especies Reactivas del Oxígeno (ROS) generadas durante los procesos de proliferación y diferenciación celular o debido a estímulos oxidantes externos, desempeñan un importante papel en el control de la síntesis de ST3Gal III y SLex, y por lo tanto en la regulación del fenotipo metastático. Además, junto al papel pro-adhesivo de la E-Selectina, este trabajo ha descrito efectos prometastáticos adicionales para esta molécula como inductora de la migración y de la secreción de VEGF a través de un mecanismo E-Selectina-SLex dependiente.

Synthesis of unusual alpha-amino acids and study of the effect of their incorporation into antimicrobial peptides. Total synthesis of biactive marine natural products and analogues thereof

The principle theme of this thesis was the synthesis of bioactive compounds. To this end, this work was focus on two main projects. The first one, which was carried out in the Department of Chemistry of the University of Girona under the supervision of Dr Montserrat Heras, concerned the synthesis of new unnatural amino acids bearing a pyrimidine ring within their side chain for incorporation into the antimicrobial peptide BP100 following a rational design in order to improve its biological profile. On the other hand, the second chapter of this thesis was developed in collaboration with the Laboratoire de Chimie Organique (ESPCI-ParisTech, Paris, France) under the guidance of Pr Janine Cossy and Dr Arseniyadis. This chapter was centered on the total synthesis of three marine natural products with complex structures and interesting biological activities: acremolide B, (–) bitungolide F and lyngbouilloside.

Role of alpha synuclein in noise induced hearing loss

The recent discovery of the contribution of alpha synuclein in the auditory system prompted further investigation of its functional role. Auditory brainstem response (ABR) and gap detection testing were completed on wild-type and transgenic M83 mice to assess the role of alpha synuclein in noise-induced hearing loss and central auditory function.

Histological and functional aspects of Alpha-synuclein in neurodegeneration

Alpha-synuclein has been implicated in the cellular mechanisms that control auditory sensitivity. In other systems it can also confer protection against cellular injury. Auditory brainstem response thresholds and immunohistochemistry were used to assess the ability of alpha-synuclein to protect against oxidative damage to the cochlea.

Interactions of alpha and beta synuclein proteins in auditory functioning

Alpha-synuclein is found in synaptic terminals at the base of both inner and outer hair cells, while the beta isoform is prominently localized to spiral ganglion neuron cell bodies. The present study assessed the role of beta-synuclein in auditory function, and potential interactions between isoforms.
