Energía del siglo XXI: Perspectivas europeas y tendencias globales

Fins ara, el desenvolupament del mercat interior ha patit les limitacions derivades de la manca d'una política energètica comú i, en el pla internacional, la UE, fortament dependent dels aprovisionaments externs, no ha estat capaç de parlar amb una sola veu a l'hora de negociar acords de subministrament amb els seus principals proveïdors de petroli i gas, i amb els països de trànsit. Sens dubte, la visió intergubernamentalista de la integració europea és la més indicada per explicar les mancances assenyalades en la mesura que la política energètica, especialment, en les vessants de la seguretat dels aprovisionaments i la independència energètica, forma part del nucli dur de la sobirania estatal. Només cal comprovar que, fins ara, tot i els continus avenços del mercat interior, els tractats han mantingut el vot per unanimitat del Consell pel que fa a les decisions relacionades amb l'energia, excloent, és clar, al Parlament Europeu (PE).. El Tractat de Lisboa introdueix un canvi de tendència en vincular la política energètica, alhora, al medi ambient i al "esperit de solidaritat entre els Estats membres "amb l'objectiu de garantir el funcionament del mercat de l'energia i la seguretat de l'abastament energètic en la Unió, i fomentar l'eficiència energètica i l'estalvi energètic i el desenvolupament d'energies noves i renovables i la interconnexió de les xarxes energètiques. Per primera vegada, el Parlament Europeu i el Consell establiran conjuntament (codecisió), les mesures necessàries per assolir els esmentats objectius. aquesta formulació reflecteix els canvis que està experimentant la política energètica a la Unió i que constitueixen l'objecte central d'aquest llibre: la seguretat de energètica i seva connexió amb el canvi climàtic.

Mutational and acquired carbapenem resistance mechanisms in multidrug resistant Pseudomonas aeruginosa clinical isolates from Recife, Brazil

An investigation was carried out into the genetic mechanisms responsible for multidrug resistance in nine carbapenem-resistant Pseudomonas aeruginosaisolates from different hospitals in Recife, Brazil. Susceptibility to antimicrobial agents was determined by broth microdilution. Polymerase chain reaction (PCR) was employed to detect the presence of genes encoding β-lactamases, aminoglycoside-modifying enzymes (AMEs), 16S rRNA methylases, integron-related genes and OprD. Expression of genes coding for efflux pumps and AmpC cephalosporinase were assessed by quantitative PCR. The outer membrane proteins were separated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The blaSPM-1, blaKPC-2 and blaGES-1 genes were detected in P. aeruginosaisolates in addition to different AME genes. The loss of OprD in nine isolates was mainly due to frameshift mutations, premature stop codons and point mutations. An association of loss of OprD with the overexpression of MexAB-OprM and MexXY-OprM was observed in most isolates. Hyper-production of AmpC was also observed in three isolates. Clonal relationship of the isolates was determined by repetitive element palindromic-PCR and multilocus sequence typing. Our results show that the loss of OprD along with overexpression of efflux pumps and β-lactamase production were responsible for the multidrug resistance in the isolates analysed.

Mg/Ca and Sr/Ca ratios of ostracod valves from living species of Lake Geneva

The Mg/Ca and Sr/Ca ratios of living ostracods belonging to 15 different species and sampled monthly over a one year-cycle at five sites (2, 5, 13, 33, and 70 m water depths) in western Lake Geneva (Switzerland) are compared to the oxygen and carbon isotope compositions measured on the same samples as well as to the temperature and chemical composition of the water (δ18OH2O, δ13CDIC, Mg/CaH2O, and Sr/CaH2O) at the time of ostracod calcification. The results indicate that trace element incorporation varied at the species level, mainly because of the ecological and biological differences between the different species (life-cycle, (micro-)habitat preference, biomineralisation processes) and the control thereof on trace element incorporation of the ostracods. In littoral zones, the Mg/Ca and Sr/Ca of ostracod valves increase as temperature and Mg/Ca and Sr/Ca of water increase during spring and summer, hence reflecting mainly seasonal variations. However, given that for Lake Geneva the Mg/Ca and Sr/Ca of water also vary with temperature, it is not possible to distinguish the effects of temperature from those of changes in chemical composition of water on the trace element content in ostracod valves. Results support that both water temperature and water Mg/Ca and Sr/Ca ratios control the final trace element content of Cyprididae valves. In contrast, the trace element content of species living in deeper zones of the basin is influenced by variations in the chemical composition of the pore water for the infaunal species. Trace element content measured for these specimens cannot, therefore, be used to reconstruct the compositions of the water lake bottom. In addition, incorporation of Mg and Sr into the shell differs from one family, sub-family, or even species to the other. This suggests that the distinctive Mg and Sr partition coefcients for the analysed taxa result from different valve calcification strategies that may be phylogenetic.

Localization of the cannabinoid CB1 receptor and the 2-AG synthesizing (DAGLα) and degrading (MAGL, FAAH) enzymes in cells expressing the Ca(2+)-binding proteins calbindin, calretinin, and parvalbumin in the adult rat hippocampus.

The retrograde suppression of the synaptic transmission by the endocannabinoid sn-2-arachidonoylglycerol (2-AG) is mediated by the cannabinoid CB1 receptors and requires the elevation of intracellular Ca(2+) and the activation of specific 2-AG synthesizing (i.e., DAGLα) enzymes. However, the anatomical organization of the neuronal substrates that express 2-AG/CB1 signaling system-related molecules associated with selective Ca(2+)-binding proteins (CaBPs) is still unknown. For this purpose, we used double-label immunofluorescence and confocal laser scanning microscopy for the characterization of the expression of the 2-AG/CB1 signaling system (CB1 receptor, DAGLα, MAGL, and FAAH) and the CaBPs calbindin D28k, calretinin, and parvalbumin in the rat hippocampus. CB1, DAGLα, and MAGL labeling was mainly localized in fibers and neuropil, which were differentially organized depending on the hippocampal CaBPs-expressing cells. CB(+) 1 fiber terminals localized in all hippocampal principal cell layers were tightly attached to calbindin(+) cells (granular and pyramidal neurons), and calretinin(+) and parvalbumin(+) interneurons. DAGLα neuropil labeling was selectively found surrounding calbindin(+) principal cells in the dentate gyrus and CA1, and in the calretinin(+) and parvalbumin(+) interneurons in the pyramidal cell layers of the CA1/3 fields. MAGL(+) terminals were only observed around CA1 calbindin(+) pyramidal cells, CA1/3 calretinin(+) interneurons and CA3 parvalbumin(+) interneurons localized in the pyramidal cell layers. Interestingly, calbindin(+) pyramidal cells expressed FAAH specifically in the CA1 field. The identification of anatomically related-neuronal substrates that expressed 2-AG/CB1 signaling system and selective CaBPs should be considered when analyzing the cannabinoid signaling associated with hippocampal functions.

Analysis of genes encoding penicillin-binding proteins in clinical isolates of Acinetobacter baumannii.

There is limited information on the role of penicillin-binding proteins (PBPs) in the resistance of Acinetobacter baumannii to β-lactams. This study presents an analysis of the allelic variations of PBP genes in A. baumannii isolates. Twenty-six A. baumannii clinical isolates (susceptible or resistant to carbapenems) from three teaching hospitals in Spain were included. The antimicrobial susceptibility profile, clonal pattern, and genomic species identification were also evaluated. Based on the six complete genomes of A. baumannii, the PBP genes were identified, and primers were designed for each gene. The nucleotide sequences of the genes identified that encode PBPs and the corresponding amino acid sequences were compared with those of ATCC 17978. Seven PBP genes and one monofunctional transglycosylase (MGT) gene were identified in the six genomes, encoding (i) four high-molecular-mass proteins (two of class A, PBP1a [ponA] and PBP1b [mrcB], and two of class B, PBP2 [pbpA or mrdA] and PBP3 [ftsI]), (ii) three low-molecular-mass proteins (two of type 5, PBP5/6 [dacC] and PBP6b [dacD], and one of type 7 (PBP7/8 [pbpG]), and (iii) a monofunctional enzyme (MtgA [mtgA]). Hot spot mutation regions were observed, although most of the allelic changes found translated into silent mutations. The amino acid consensus sequences corresponding to the PBP genes in the genomes and the clinical isolates were highly conserved. The changes found in amino acid sequences were associated with concrete clonal patterns but were not directly related to susceptibility or resistance to β-lactams. An insertion sequence disrupting the gene encoding PBP6b was identified in an endemic carbapenem-resistant clone in one of the participant hospitals.

Avaliação de empresas e probabilidade de negociação com informação privilegiada no mercado brasileiro de capitais

O objetivo no estudo apresentado neste artigo foi investigar a influência da assimetria de informação na avaliação de empresas no mercado brasileiro de capitais. Para tanto, foi realizado um estudo com base na mensuração da assimetria de informação na negociação de ações e no modelo de avaliação de empresas proposto por Ohlson (1995). Analisou-se a relação da assimetria informacional e os preços de 198 ações listadas na Bolsa de Valores, Mercadorias e Futuros de São Paulo (BM&FBovespa), durante os quatro trimestres do ano de 2011. Os resultados sugerem que a assimetria de informações tem conteúdo informacional adicional na avaliação de empresas, principalmente para aquelas companhias não listadas nos segmentos diferenciados de governança corporativa.

La inseguretat al nucli antic i barri Plnas/Ca L'Escori. El Vendrell: diagnòstic multifactorial per una proposta d'intervencions més establs, responsables i duradores

El treball té com a finalitat l’estudi dels conflictes de convivència que tenen lloc amb l’ocupació i usos dels espais públics al barri dels Planas/Ca L’Escori i nucli antic del Vendrell. L’ús i l’apropiació dels espais públics és un dels aspectes fonamentals a tenir en compte en l’estudi de la vida quotidiana dels ciutadans/nes dels llocs poblats. Aquesta experiència no és igual per a totes les persones ja que segons el gènere, l’edat, així com la classe social i les identitats ètniques, es viu i percep de forma diferent, amb la qual cosa, per aproximar-se a la comprensió de l’ús diferencial del espai cal fer-ho des d’una òptica multidisciplinària. Aquest indret mostra una heterogeneïtat social i ètnica dels veïns i les veïnes que fa especialment interessant l’anàlisi dels espais públics d’aquesta zona. La riquesa poblacional (persones residents de tota la vida, persones immigrades d’altres regions d’Espanya o d’altres països, etc.) comporta una gran diversitat d’experiències quotidianes i al mateix temps, una gran varietat d’opinions sobre la percepció i la concepció dels espais públics, alhora genera un aprofitament i ús intensiu o continuat a la via pública que es tradueix en el què anomenaré "convivència intensiva". Per la qual cosa crec oportú dedicar esforços per tal d'analitzar l’ús i l’abús dels espais públics i de la convivència en aquest barri del Vendrell. Aquesta polivalència en els usos dels espais, fa que situï com a focus del meu treball, una característica que acostuma a ser, amb més o menys fonament, un agreujament de molts problemes. En concret, faig referència a l’ús i l’abús de l’espai públic i, si els conflictes que es produeixen al seu voltant respon a una fonamentació real o respon a altres factors, com poden ser causes de malestar per la immigració o la percepció social que d'aquesta es té i, que moltes vegades té un paper destacat com a causa d'estigmatització de les pràctiques de sociabilitat en públic dels immigrants, o d'una part d'ells, la qual cosa provoca una tensió estructural amb dificultats de gestió.

The Candida albicans plasma membrane protein Rch1p, a member of the vertebrate SLC10 carrier family, is a novel regulator of cytosolic Ca(2+) homoeostasis.

Candida albicans RCH1 (regulator of Ca(2+) homoeostasis 1) encodes a protein of ten TM (transmembrane) domains, homologous with human SLC10A7 (solute carrier family 10 member 7), and Rch1p localizes in the plasma membrane. Deletion of RCH1 confers hypersensitivity to high concentrations of extracellular Ca(2+) and tolerance to azoles and Li(+), which phenocopies the deletion of CaPMC1 (C. albicans PMC1) encoding the vacuolar Ca(2+) pump. Additive to CaPMC1 mutation, lack of RCH1 alone shows an increase in Ca(2+) sensitivity, Ca(2+) uptake and cytosolic Ca(2+) level. The Ca(2+) hypersensitivity is abolished by cyclosporin A and magnesium. In addition, deletion of RCH1 elevates the expression of CaUTR2 (C. albicans UTR2), a downstream target of the Ca(2+)/calcineurin signalling. Mutational and functional analysis indicates that the Rch1p TM8 domain, but not the TM9 and TM10 domains, are required for its protein stability, cellular functions and subcellular localization. Therefore Rch1p is a novel regulator of cytosolic Ca(2+) homoeostasis, which expands the functional spectrum of the vertebrate SLC10 family.
