Neurogenesis in the diencephalon of the adult zebrafish: an immunohistochemical study using the proliferating cell nuclear antigen (PCNA) as marker

[Resumen] La proliferación celular a lo largo de la vida de los vertebrados recae en células progenitoras que se agrupan en regiones conocidas como zonas de proliferación. Si bien en el encéfalo adulto de mamíferos la proliferación está bastante restringida, en peces teleósteos las zonas proliferativas están ampliamente distribuidas a lo largo del eje antero-posterior del encéfalo. En este trabajo se estudiará la proliferación celular en el diencéfalo del pez cebra adulto mediante técnicas inmunhistoquímicas empleando como marcador el antígeno nuclear de proliferación celular (PCNA). Los resultados obtenidos evidencian células en proliferación en zonas del área preóptica, tálamo, sinencéfalo, epitálamo e hipotálamo del diencéfalo del pez cebra. Asimismo se evaluará el papel de la PCNA como marcador y se discutirán los resultados obtenidos con otras especies de teleósteos y vertebrados.[Abstract] Lifelong proliferation in vertebrates relies on progenitor cells that are clustered in regions known as proliferative zones. Although in the adult brain of mammals this proliferation is greatly restricted, in teleost these proliferative zones are widespread through the anteroposterior axis of the encephalon. In this work is studied the cellular proliferation in the diencephalon of the adult zebrafish by means immunohistochemical techniques using the proliferating cell nuclear antigen (PCNA) as marker. The results show proliferation cells in regions of the preoptic area, thalamus, synencephalon, epithalamus and hypothalamus of the zebrafish diencephalon. Furthermore the role of the PCNA as marker and the results are assessed.Traballo fin de grao (UDC.CIE). Bioloxía. Curso 2014/201

Ornithodoros quilinensis sp. nov. (Acari, Argasidae), a new tick species from the Chacoan region in Argentina

Ornithodoros quilinensis sp. nov. (Acari: Argasidae) is described from larvae collected on the small rodents Graomys centralis (Cricetidae: Sigmodontinae) in Argentina. The diagnostic characters for this new species are a combination of small size (520-540 μm), a dorsal plate oval in shape with a length of approximately 200 μm, 14 pairs of dorsal setae, hypostome short and narrower at the base (length from Ph1 to apex 133 μm (120-141)) with dental formula 2/2 and apex blunt, and the capsule of the Haller's organ irregular in shape and without reticulations. The analysis of the 16S rDNA sequences available for the genus Ornithodoros indicate that, phylogenetically, O. quilinensis represents an independent lineage only related to a Bolivian tick species of the genus Ornithodoros yet not formally described.Fil: Venzal, José M..

Liquid–liquid equilibria of mixtures containing methyl acetate + methanol + hexane or heptane

This paper reports the results of a new experimental study of liquid–liquid equilibria for the mixtures methyl acetate + methanol + hexane or heptane at atmospheric pressure and at (268.15, 278.15, 288.15, and 298.15)K. The equilibrium compositions were measured by gas chromatography from samples split isothermally into a glass-stirred device, and phase diagrams are reported at each temperature. The experimentally determined liquid-liquid equilibria were satisfactorily correlated by the NRTL and UNIQUAC equations. A comparative analysis was performed by application of UNIFAC group contribution method and its modifications to predict experimental liquid–liquid equilibria (LLE) behavior of these ternary mixtures. A poor prediction was observed from these contribution methods

Miniature transposable sequences are frequently mobilized in the bacterial plant pathogen Pseudomonas syringae pv. phaseolicola

Mobile genetic elements are widespread in Pseudomonas syringae, and often associate with virulence genes. Genome reannotation of the model bean pathogen P. syringae pv. phaseolicola 1448A identified seventeen types of insertion sequences and two miniature inverted-repeat transposable elements (MITEs) with a biased distribution, representing 2.8% of the chromosome, 25.8% of the 132-kb virulence plasmid and 2.7% of the 52-kb plasmid. Employing an entrapment vector containing sacB, we estimated that transposition frequency oscillated between 2.661025 and 1.161026, depending on the clone, although it was stable for each clone after consecutive transfers in culture media. Transposition frequency was similar for bacteria grown in rich or minimal media, and from cells recovered from compatible and incompatible plant hosts, indicating that growth conditions do not influence transposition in strain 1448A. Most of the entrapped insertions contained a full-length IS801 element, with the remaining insertions corresponding to sequences smaller than any transposable element identified in strain 1448A, and collectively identified as miniature sequences. From these, fragments of 229, 360 and 679-nt of the right end of IS801 ended in a consensus tetranucleotide and likely resulted from one-ended transposition of IS801. An average 0.7% of the insertions analyzed consisted of IS801 carrying a fragment of variable size from gene PSPPH_0008/PSPPH_0017, showing that IS801 can mobilize DNA in vivo. Retrospective analysis of complete plasmids and genomes of P. syringae suggests, however, that most fragments of IS801 are likely the result of reorganizations rather than one-ended transpositions, and that this element might preferentially contribute to genome flexibility by generating homologous regions of recombination. A further miniature sequence previously found to affect host range specificity and virulence, designated MITEPsy1 (100-nt), represented an average 2.4% of the total number of insertions entrapped in sacB, demonstrating for the first time the mobilization of a MITE in bacteria

CBM Challenges and Opportunities for O&M of the Johan Sverdrup Oil and Gas Field

Financiado para publicación en acceso aberto: Universidade da Coruña/CISUG[Abstract] Paper describes the challenges and forward developments to face up on Operation and Maintenance (O&M) issues at the Johan Sverdrup field (Blocks: PL 501, PL 265 and PL 502), on the phases (Concept and Design, Construction and Hook-up, Commissioning, Operations and Maintenance, and Recycling), and a research study of the Oil&Gas profitability. Estimated reserves are between 1.8 billion to 2.8 billion bbl, so assessing the total risk of the field development is crucial. Although, development is estimated to cost up to $31 billion, but the full life-cycle price tag, including operating costs through 2068, is around$58.33 billion. The purpose of this paper is to demonstrate a conceptual methodology analysis framework, for understanding how analysis of cost and benefits, are carry out for assessment and implementation of the Condition Base Monitoring (CBM) and measure the total OPEX (Operate Expenditure/Operating Cost). As well as a specific maintenance philosophy and conceptual approach on the business cases studies of the project lead, to a cost-effective solution. Paper begins by providing a background for analyzing the life-cycle impacts during the life of the field (50 years), and describing measures to implement during the O&M strategies. Follows by targeting the expectations, which one rest on profitability and optimization of the field, with oil prices above $60 per barrel (proved on Case 3). The harvest will, therefore, be profitable even after the price crash. Life Cycle Cost (LCC) analysis (Alternatives A and B) focuses and identifies “Cost Items” (Cost Drivers) that the project carries. Achieved a reliable “concept development” is the greatest ambition, but uncertainties on Maintenance strategies and programs, have showed high cost at early phases. The aim was to measure the actual costs against predicted LCC and to calculate the cumulative costs throughout a product's Life Cycle (LC) of the assets. Discussed and summarized the extent to which these costs and benefits may already take into account and how the CBM strategy mechanism should be works based on a model built. Finally, is demonstrated through calculating an ″downtime scenario″ that could happens, which one creates Deferred Production Costs. Also, has been estimate the cost-benefit analysis (CBA) might be applicable on the researched project development ratio (cost vs. benefit), with overall maintenance effectiveness strategy under study on the LCC Alternative 2. Therefore, describing the maintenance support functionality, based on input obtained from CBM systems and a predictive, periodic maintenance plan is indispensable, in order to cut off potential costs, target future benefits and guaranty a safety robust production installation. At the end, the paper addresses the future performance outlook development in the Oil&Gas Industry as whole, stating essential optimization valuable principles
