Identification and study of a Candida albicans protein homologous to Saccharomyces cerevisiae Ssr1p, an internal cell-wall protein
2003
After screening of aCandida albicansgenome database, the product of an ORF (IPF 3054) that has 62 % homology withSaccharomyces cerevisiaeSsr1p, an internal cell-wall protein, was identified and named CaSsr1p. The deduced amino acid sequence shows that CaSsr1p contains an N-terminal hydrophobic signal peptide, is rich in Ser and Thr amino acids and has a potential glycosylphosphatidylinositol-attachment signal. CaSsr1p is released following degradation of isolated cell walls by zymolyase (mainly a 1,3-β-glucanase) and therefore seems to be covalently linked to theβ-glucan of the cell walls. Both disruption and overexpression of theCaSSR1gene caused an increased sensitivity to calcofluor whit…
La utilización de marfil de cachalote en el Calcolítico de Portugal
2013
Scientific analysis were undertaken within a research project concerning ivory objects from the Chalcolithic to Early Bronze Age of the Iberian Peninsula. In several of the analyses of objects from Portuguese Estremadura, especially V-perforated buttons, we could detect for the first time the presence of sperm whale ivory. This highlights the advantage and necessity of scientific analysis of ivory. It also clearly demonstrates that not all ivory used was ivory from African or Asian elephants, but we also did find ivory from the extinct Elephas antiquus, the hippopotamus and in this case sperm-whale. Thus, already in the Chalcolithic the raw material provenience was highly diverse, which in …
El Yacimiento de Colata (Valencia, España) y los ‘poblados de silos’ en la fachada mediterránea de la Península Ibérica
2004
Recientemente se han abierto nuevas líneas de investigación revisando algunas categorías empleadas en la interpretación funcional de las estructuras, modificando aspectos metodológicos en el análisis de los rellenos y matizando algunas afirmaciones de índole socioeconómico fundamentadas en los cálculos de producción- En este contexto se presentan los resultados del yacimiento de Colata (Valencia, España), con la intención de contribuir a ese panorama de renovación en la interpretación de los yacimientos neolíticos con silos. Recently, new lines of research have been opened by reviewing some categories used in the functional interpretation of structures, modifying methodological aspects in t…
Loss of virulence in Ustilago maydis by Umchs6 gene disruption
2003
A gene encoding a sixth chitin synthase (Umchs6, sequence GenBank accession No. AF030554) from the plant pathogenic hemibasidiomycete Ustilago maydis (DC.) Cda. was isolated and characterized. The predicted protein is 1103 amino acids in length with a calculated molecular mass of 123.5 kDa. a2b2 null mutants were obtained by substitution of a central fragment of the Umchs6 gene with the hygromycin resistance cassette, and a1b1 null mutants were obtained by genetic recombination in plants of an a2b2Δch6 and a wild-type a1b1 strain. The mutation had no effect on the dimorphic transition in vitro or on mating, and growth rate of the mutants was only slightly reduced. On the other hand, they di…
Influence de différentes pratiques agricoles sur la qualité et la santé des sols : étude de cas sur des vergers slovènes irrigués ou en agriculture b…
2011
Underestimation of soil properties and poor understanding of soil conditions can have many negative consequences, which results in quality or quantity of yield, soil degradation or even environmental pollution. According to importance of agricultural practices, our study focused on their impact on soil quality and health. The research took place from November 2003 to October 2007 in apple orchards in north-eastern Slovenia where two frequent agricultural practices were investigated: (i) drip irrigation on Calcaric Cambisol and its effects on structural stability and microbial biomass at Gačnik experimental station and (ii) combination of organic fertiliser (Campo guano) and liming in organi…
Raw material procurement and selection in Southeast Iberia’s early metallurgy
2020
The role of metallurgy in the Copper Age communities of the Iberian Southeast is a recurrent question of archaeological research in western Europe. Based on lead isotope and trace element analyses of archaeometallurgical remains, this paper addresses the territorial organisation of metallurgical production during the Copper Age (3100-2200 cal BC) in the Vera Basin (Almería, Spain), the region with the earliest metallurgical evidence in western Europe. This paper comprises the study of materials from the three main settlements with metallurgical activity in the area (Las Pilas, Santa Bárbara and Almizaraque), as well as some metal objects from these and other sites (La Encantada I, Loma…
An Archimedean research theme: the calculation of the volume of cylindrical groins
2010
Starting from Archimedes’ method for calculating the volume of cylindrical wedges, I want to get to describe a method of 18th century for cilindrical groins thought by Girolamo Settimo and Nicolo di Martino. Several mathematicians studied the measurement of wedges, by applying notions of infinitesimal and integral calculus; in particular I examinated Settimo’s Treatise on cylindrical groins, where the author solved several problems by means of integrals.
Modulació de l'artritis gotosa per dues molècules inhibidores de la caspasa-1
2020
L’artritis gotosa es una de les malalties articulars més freqüents d’artritis inflamatòria. Es produeix per la deposició d’urat monosòdic (MSU) en les articulacions, donant lloc a episodis aguts d’inflamació, que poden ser persistents i arribar a cronificar-se. La fagocitosi dels cristalls d’MSU pels neutròfils i macròfags genera la producció de ROS i l’activació de l’NFkappaB, alliberant citocines i activant l’NLRP3. Aquest inflamasoma indueix l’activació de la caspasa1 i la consegüent producció de les formes actives IL1beta i IL18. Les calcones són un grup de la família dels flavonoides, que han demostrat propietats antiinflamatòries i antiartrítiques, actuant sobre diverses dianes terapè…
