Seville, Spain

Pablo de Olavide University in Spanish) is a public university in Seville, Spain. UPO offers both undergraduate and graduate programs in the traditional majors, as well as in biotechnology, environmental science, humanities, labor relations, second language acquisition, social work, sports science, and translationPablo de Olavide University was founded in 1997, making it one of the newest public universities in Spain. The UPO has over 10,000 students and is growing constantly since its inception. The university is named after the Spanish-Peruvian politician Pablo de Olavide , who contributed notably to planning the city of Seville. Being a relatively young university, the UPO was planned as a North American-style campus with dedicated academic and residential space.Its 345-acres spread out southeast of Seville over the municipalities of Dos Hermanas, Alcalá de Guadaíra and Seville. Its facilities are modern, including campus-wide Wifi and Internet access, computer, television, video and audio centers, an open access library, sports facilities, and science laboratories.It has numerous sports facilities, lawns, gym and a huge library where you can find books from every subject.This University also boasts a student union building and offers easy transportation to the city center by bus or metro.

Nanostructured films of metal-oxide semiconductors are the focus of intensive research nowadays due to their applications in the current quest for new sources of clean energy. Metal-oxides like TiO 2 and ZnO can be used to make efficient photoanodes for photoelectrochemical solar cells and nanostructured substrates for photocatalytic production of non-polluting fuels. In these applications electron transport through the nanostructure is crucial to achieve a good photon-to-electron quantum efficiency. In this paper the current knowledge of the electron transport mechanisms that take place in these systems is reviewed, highlighting the influence of energy and morphological disorder on the efficacy of the transport process. A special connection is made between the specificity of the electron transport in these systems and their applications in solar cells and photocatalytic devices. © 2012 Elsevier Ltd. Source

Micronutrient deficiencies, especially those related to iodine and iron, are linked to different cognitive impairments, as well as to potential long-term behavioral changes. Among the cognitive impairments caused by iron deficiency, those referring to attention span, intelligence, and sensory perception functions are mainly cited, as well as those associated with emotions and behavior, often directly related to the presence of iron deficiency anemia. In addition, iron deficiency without anemia may cause cognitive disturbances. At present, the prevalence of iron deficiency and iron deficiency anemia is 2%–6% among European children. Given the importance of iron deficiency relative to proper cognitive development and the alterations that can persist through adulthood as a result of this deficiency, the objective of this study was to review the current state of knowledge about this health problem. The relevance of iron deficiency and iron deficiency anemia, the distinction between the cognitive consequences of iron deficiency and those affecting specifically cognitive development, and the debate about the utility of iron supplements are the most relevant and controversial topics. Despite there being methodological differences among studies, there is some evidence that iron supplementation improves cognitive functions. Nevertheless, this must be confirmed by means of adequate follow-up studies among different groups. © 2014 Jáuregui-Lobera. Source

At the present, emotion is considered as a critical point of human behaviour, and thus it should be embedded within the reasoning module when an intelligent system or a autonomous robot aims to emulate or anticipate human reactions. Therefore, current research in Artificial Intelligence shows an increasing interest in artificial emotion research for developing human-like systems. Based on Thayer's emotion model and Fuzzy Cognitive Maps, this paper presents a proposal for forecasting artificial emotions. It provides an innovative method for forecasting artificial emotions and designing an affective decision system. This work includes an experiment with three simulated artificial scenarios for testing the proposal. Each scenario generate different emotions according to the artificial experimental model. © 2012 Elsevier B.V. All rights reserved. Source

PLoS pathogens

The O-mannosyltransferase Pmt4 has emerged as crucial for fungal virulence in the animal pathogens Candida albicans or Cryptococcus neoformans as well as in the phytopathogenic fungus Ustilago maydis. Pmt4 O-mannosylates specific target proteins at the Endoplasmic Reticulum. Therefore a deficient O-mannosylation of these target proteins must be responsible for the loss of pathogenicity in pmt4 mutants. Taking advantage of the characteristics described for Pmt4 substrates in Saccharomyces cerevisiae, we performed a proteome-wide bioinformatic approach to identify putative Pmt4 targets in the corn smut fungus U. maydis and validated Pmt4-mediated glycosylation of candidate proteins by electrophoretic mobility shift assays. We found that the signalling mucin Msb2, which regulates appressorium differentiation upstream of the pathogenicity-related MAP kinase cascade, is O-mannosylated by Pmt4. The epistatic relationship of pmt4 and msb2 showed that both are likely to act in the same pathway. Furthermore, constitutive activation of the MAP kinase cascade restored appressorium development in pmt4 mutants, suggesting that during the initial phase of infection the failure to O-mannosylate Msb2 is responsible for the virulence defect of pmt4 mutants. On the other hand we demonstrate that during later stages of pathogenic development Pmt4 affects virulence independently of Msb2, probably by modifying secreted effector proteins. Pit1, a protein required for fungal spreading inside the infected leaf, was also identified as a Pmt4 target. Thus, O-mannosylation of different target proteins affects various stages of pathogenic development in U. maydis. Source

Aim The genus Abies exemplifies plant diversification related to long-term climatic, geological and evolutionary changes. Today, the Mediterranean firs comprise nine species, one natural hybrid and several varieties. Here I summarize current knowledge concerning the origin and evolution of the genus Abies in the Mediterranean Basin and propose a comprehensive hypothesis to explain the isolation and speciation pattern of Mediterranean firs. Location The Mediterranean Basin. Methods The literature on Abies was reviewed, focusing on the morphology, fossil records, molecular ecology, phytosociology and biogeography of the genus in the Mediterranean Basin. Results Abies fossils from the western Mediterranean indicate a wide Tertiary circum-Mediterranean distribution of the Abies ancestor. Palaeogeographical data also suggest a single eastern Mediterranean Tertiary ancestor. Following the Miocene to Pliocene climate crisis and marine transgressions, the ancestor of the northern Mediterranean firs is hypothesized to have separated into two eastern groups, one on the Balkan Peninsula and the other in Asia Minor. However, land bridges may have permitted gene flow at times. A southward migration of A. alba to refugia, where older fir species may have remained isolated since the Miocene, could explain recent findings indicating that morphologically distant species are more closely related than expected based on such morphological classification. Main conclusions The Abies genus appears to have undergone significant morphological differentiation that does not necessarily imply reproductive isolation. That is, long-term Mediterranean Basin dryness along a south-eastern to north-western gradient may have caused an initial Miocene-Pliocene speciation sequence. Pleistocene glacial cycles probably forced migrations to occur, leading to repeated contact between fir species in glacial refugia. © 2011 Blackwell Publishing Ltd. Source
