3D Reconstruction and Modelling of the Sierras Exteriores Aragonesas (Southern Pyrenees, Spain). Structural Evolution of the Pico del Águila anticline

Author(s): Vidal Royo, Oskar
Description: [eng] This Thesis reports on the integration of different modelling techniques to construct a unified and better constrained conceptual model of structural evolution of the Pico del Águila anticline (External Sierras, Southern Pyrenees, Spain). The structure is a well-known example of detachment fol...

Ecology of the benthic macroinvertebrates in the lower Ebro River: community characterization, population dynamics and bioaccumulation of pollutants in response to environmental factors / Ecologia dels macroinvertebrats bentònics al tram baix del riu Ebre: caracterització de la comunitat, dinàmica de poblacions i bioacumulació de contaminants en resposta a factors ambientals

Author(s): Cid Puey, Núria
Description: [eng] The effects of the main anthropogenic impacts in the fluvial ecosystem of the lower Ebro River are evaluated along the five chapters of the present thesis, using the benthic macroinvertebrate community as a bioindicator. Different approaches are integrated in function of the type of stressor, ...

Paleogene chronostratigraphy of the SE margin of the Ebro Basin: biochronological and tectonosedimentary evolution Implications = Cronostratigrafia del paleogen del marge SE de la conca de l’Ebre: Implicacions biocronològiques i evolució tectonosedimentaria

Description: [eng] This PhD-Thesis presents a new chronostratigraphy of the Paleogene sedimentary record of the SE margin of the Eastern Ebro Basin. It is based on a number of magnetostratigraphic sections and its integration with marine and continental biochronological data. A robust correlation with the geomag...

Respostes de l’ús del territori al paisatge en mamífers de mida gran i mitjana Responses Of Territory Use To Landscape In Large And Medium-Sized Mammals

Description: [cat] L’objectiu d’aquesta tesi és avançar en el coneixement de l’ús que els meso-mamífers fan del paisatge mediterrani amb diferents nivells d’urbanització i de quina manera les variacions en aquest s’associen a variacions en el seu comportament, ecologia i, per tant, en la conservació. Tenint en c...

Factors que afecten l’èxit d’expansió de poblacions d’aus en medis transformats per l’home: l’arpella "Circus aeruginosus" a la Vall de l’Ebre Factors affecting expansion success of bird populations in human-transformed environments: the marsh harrier Circus aeruginosus in the Ebro Valley

Description: [eng] Change in species geographic ranges is a natural phenomenon, but the rate and magnitude of such change has significantly increased due to anthropogenic causes. The rate at which a population spreads/contracts through space is a function of the rates of population growth and dispersal, coupled ...

Detection of marine toxins using cell-based assays and Characterization of toxin profiles in ciguatera-related natural samples: microalgae and fish. / (Detección de toxinas marinas mediante ensayos celulares y Caracterización del perfil toxinico en muestras naturales asociadas a la ciguatera: microalgas y pescado

Author(s): Caillaud, Amandine
Description: [eng] The suitability of neuroblastoma cell-based assays (Neuro-2a CBAs) was examined in order to characterize toxin profiles in ciguatera-related natural samples: microlagae (Gambierdiscus spp. and Prorocentrum rhathymum) and ciguatera-suspected fish samples from the Canary Islands. The elimination...

The Role of the Cell Cycle in Human Embryonic Stem Cell Self-Renewal and Pluripotency (La función del ciclo celular en la auto-renovación y la pluripotencia de las células madre embrionarias humanas)

Description: [eng] Embryonic stem cells (ESC) are derived from the inner cell mass (ICM) of the blastocyst and have the capacity for unlimited proliferation while retaining their potential to differentiate into a wide variety of cell types when cultured in vitro. These properties have made of human embryonic ste...

Role of Methylation in Modulating MAPK Signaling. Implications in Melanoma. Papel de la metilación como modulador de la señalización en MAPK. Implicaciones en melanoma.

Description: 1. General Overview MTAP is a key enzyme in the methionine salvage pathway and controls the levels of methylthioadenosine (MTA). Lost of MTAP, which is frequent in melanoma, results in higher intra and extracellular MTA levels. As MTA is an inhibitor of methylation reactions within the cell, we deci...

The first 3D structural model of an eukaryotic heteromeric aminoacid transporter Primer model estructural en 3D d’ un transportador heteromèric d’aminoàcids eucariota

Description: [eng] Introduction Heteromeric amino acid transporters (HATs) are composed of a heavy subunit (rBAT or 4F2hc) and a light subunit (b0 + AT, ASC1, LAT1, LAT2, y + LAT1, y + LAT2 and xCT), joined by a disulfide bridge (Chillaron et al. 2001). rBAT and 4F2hc are type II membrane glycoproteins (N-termi...
