Presidents and parties in regional politics: Italy and Spain compared

This article examines the relationship between political parties and regional presidents in Italy and Spain, adopting a comparative case study approach based on extensive archival analysis and in-depth interviews with regional politicians. The findings confirm a strong pattern of growing presidentialism at regional level, regardless of whether there are formal mechanisms for direct election, and regardless of the partisan composition of regional government. Regional presidents tend to exert their growing power through a personalised control of regional party organisations, rather than governing past parties in a direct appeal to the electorate. Nevertheless, parties can still present a significant constraint on regional presidents, so successful regional presidents tend to maintain a mediating form of leadership and fully exploit the opportunities for party patronage to build up their support and smooth governing tensions. An autonomist drive helps presidents hold together disparate coalitions or loose parties at regional level, but their lack of internal coherence presents major problems when it comes to political succession.

Genotyping Mycobacterium bovis from cattle in the Central Pampas of Argentina: temporal and regional trends

Mycobacterium bovis is the causative agent of bovine tuberculosis (TB), a disease that affects approximately 5% of Argentinean cattle. Among the molecular methods for genotyping, the most convenient are spoligotyping and variable number of tandem repeats (VNTR). A total of 378 samples from bovines with visible lesions consistent with TB were collected at slaughterhouses in three provinces, yielding 265 M. bovis spoligotyped isolates, which were distributed into 35 spoligotypes. In addition, 197 isolates were also typed by the VNTR method and 54 combined VNTR types were detected. There were 24 clusters and 27 orphan types. When both typing methods were combined, 98 spoligotypes and VNTR types were observed with 27 clusters and 71 orphan types. By performing a meta-analysis with previous spoligotyping results, we identified regional and temporal trends in the population structure of M. bovis. For SB0140, the most predominant spoligotype in Argentina, the prevalence percentage remained high during different periods, varying from 25.5-57.8% (1994-2011). By contrast, the second and third most prevalent spoligotypes exhibited important fluctuations. This study shows that there has been an expansion in ancestral lineages as demonstrated by spoligotyping. However, exact tandem repeat typing suggests dynamic changes in the clonal population of this microorganism.

Molecular characterization of signalling complexes involved in G-protein coupled receptor-induced cardiac hypertrophy

In response to pathological stresses, the heart undergoes a remodelling process associated with cardiac hypertrophy. Since sustained hypertrophy can progress to heart failure, there is an intense investigation about the intracellular signalling pathways that control cardiomyocyte growth. Accumulating evidence has demonstrated that most stimuli known to initiate pathological changes associated with the development of cardiac hypertrophy activate G protein-coupled receptors (GPCRs) including the αl-adrenergic- (αl-AR), Angiotensin II- (AT-R) and endothelin-1- (ET-R) receptors. In this context, we have previously identified a cardiac scaffolding protein, called AKAP-Lbc (Α-kinase anchoring protein), with an intrinsic Rho specific guanine nucleotide exchange factor activity, that plays a key role in integrating and transducing hypertrophic signals initiated by these GPCRs (Appert-Collin, Cotecchia et al. 2007). Activated RhoA controls the transcriptional activation of genes involved in cardiomyocyte hypertrophy through signalling pathways that remain to be characterized. Here, we identified the nuclear factor-Kappa Β (NF-κΒ) activating kinase ΙΚΚβ as a novel AKAP-Lbc interacting protein. This raises the hypothesis that AKAP-Lbc might promote cardiomyocyte growth by maintaining a signalling complex that promotes the activation of the pro-hypertrophic transcription factor NF-κΒ. In fact, the activation of NF- κΒ-dependent transcription has been detected in numerous disease contexts, including hypertrophy, ischemia/reperfusion injury, myocardial infarction, allograft rejection, myocarditis, apoptosis, and more (Hall, Hasday et al. 2006). While it is known by more than a decade that NF-κΒ is a critical mediator of cardiac hypertrophy, it is currently poorly understood how pro-hypertrophic signals controlling NF-κΒ transcriptional activity are integrated and coordinated within cardiomyocytes. In this study, we show that AKAP-Lbc and ΙΚΚβ form a transduction complex in cardiomyocytes that couples activation of αl-ARs to NF-κB-mediated transcriptional reprogramming events associated with cardiomyocyte hypertrophy. In particular, we can show that activation of ΙΚΚβ within the AKAP-Lbc complex promotes NF-κB-dependent production of interleukine-6 (IL-6), which, in turn, enhances foetal gene expression. These findings indicate that the AKAP-Lbc/ΙΚΚβ complex is critical for selectively directing catecholamine signals to the induction of cardiomyocyte hypertrophy.

A dynamic view of hepatitis C virus replication complexes.

Hepatitis C virus (HCV) replicates its genome in a membrane-associated replication complex (RC). Specific membrane alterations, designated membranous webs, represent predominant sites of HCV RNA replication. The principles governing HCV RC and membranous web formation are poorly understood. Here, we used replicons harboring a green fluorescent protein (GFP) insertion in nonstructural protein 5A (NS5A) to study HCV RCs in live cells. Two distinct patterns of NS5A-GFP were observed. (i) Large structures, representing membranous webs, showed restricted motility, were stable over many hours, were partitioned among daughter cells during cell division, and displayed a static internal architecture without detectable exchange of NS5A-GFP. (ii) In contrast, small structures, presumably representing small RCs, showed fast, saltatory movements over long distances. Both populations were associated with endoplasmic reticulum (ER) tubules, but only small RCs showed ER-independent, microtubule (MT)-dependent transport. We suggest that this MT-dependent transport sustains two distinct RC populations, which are both required during the HCV life cycle.

Perceived competition explains regional differences in stereotype content of immigrant groups

This research investigates differences in the stereotype content of immigrant groups between linguistic regions. We expected that immigrant groups who speak the local language of a specific linguistic region would be perceived as more competitive within this region than in another linguistic region. Further, we expected these differences would underlie regional differences in stereotype content, albeit only for the warmth dimension. Predictions were tested in the two largest linguistic regions of Switzerland. As expected, in the German-speaking region, locals perceived German immigrants as more competitive and thus as less warm, whereas in the French-speaking region, locals perceived French immigrants as more competitive and, consequently, as less warm. So, paradoxically, immigrants with strong integration potential are particularly disliked because they are regarded as direct competitors.

Use of variability in national and regional data to estimate the prevalence of lymphangioleiomyomatosis.

Background: Understanding the true prevalence of lymphangioleiomyomatosis (LAM) is important in estimating disease burden and targeting specific interventions. As with all rare diseases, obtaining reliable epidemiological data is difficult and requires innovative approaches.Aim: To determine the prevalence and incidence of LAM using data from patient organizations in seven countries, and to use the extent to which the prevalence of LAM varies regionally and nationally to determine whether prevalence estimates are related to health-care provision.Methods: Numbers of women with LAM were obtained from patient groups and national databases from seven countries (n = 1001). Prevalence was calculated for regions within countries using female population figures from census data. Incidence estimates were calculated for the USA, UK and Switzerland. Regional variation in prevalence and changes in incidence over time were analysed using Poisson regression and linear regression.Results: Prevalence of LAM in the seven countries ranged from 3.4 to 7.8/million women with significant variation, both between countries and between states in the USA. This variation did not relate to the number of pulmonary specialists in the region nor the percentage of population with health insurance, but suggests a large number of patients remain undiagnosed. The incidence of LAM from 2004 to 2008 ranged from 0.23 to 0.31/million women/per year in the USA, UK and Switzerland.Conclusions: Using this method, we have found that the prevalence of LAM is higher than that previously recorded and that many patients with LAM are undiagnosed.

Regional Determinants of Firm Entry in a Developing Country

Regional policies aiming to attract new firms are largely based on evidence that originates from Europe, the USA and Japan. This may raise doubts about the usefulness of such policies when applied to developing economies. This paper addresses this issue by providing estimates of the determinants of firm entry in the Argentinean provinces. We find that most of the determinants used in previous studies analysing developed countries are still relevant. However, there is a need for additional explanatory variables that reflect the specificities of developing economies. Key words: firm entry, regional economics, Argentina. JEL: R12; R30; C33

A Typology of agents and subjects of regional cooperation: the experience of the Mediterranean Arch

El document és el resultat d'una investigació més àmplia sobre la construcció de l'Arc Mediterrani. El seu objectiu és posar en relleu el notable grau de desenvolupament de la cooperació regional en la matèria, a través d'una anàlisi detallada de les diferents figures institucionalitzades de cooperació territorial existents (o haver existit) a la zona. L'anàlisi s'ha dut a terme des d'un punt de vista temàtic, basat en els objectius prioritaris d'aquestes institucions. En concret, les xifres estudiades es limiten a les institucions formals o les associacions de col · laboració de caràcter específic, com ara euroregions o les agrupacions europees d'interès econòmic, entès com les figures de major institucionalització dels espais transnacionals a nivell europeu. En canvi, hem deixat de banda altres figures, com Interreg (finançat pel FEDER), ja que no són entitats correctament. Encara que de vegades els acords de cooperació establerts per als projectes d'Interreg han donat lloc a algunes de les entitats estudiades aquí.

The Öresund region: A dynamic region in Europe due to inter-regional collaboration?

El cluster Medicon Valley es troba a la regió d'Oresund binacional que s'estén per Dinamarca i Suècia, inclosa la Universitat de Lund, ciutat i tercera ciutat més gran de Suècia, Malmö (veure figura 1). El 2000, aquestes dues parts nacionals estaven connectades físicament per l'establiment dels 18 quilòmetres de longitud, enllaç fix del Øresund (ponts i túnels).

El proyecto de Tratado Constitucional: la participación regional en el control de subsidiariedad

La subsidiarietat és el principi filosòfic que es nodreix de diferents fonts teòriques. Una de les definicions més comunes és la que sosté que la presa de decisions s'ha de fer el més a prop possible dels ciutadans de manera que els nivells superiors de govern s'ocupin només del que els nivells inferiors no estiguin en condicions de dur a terme eficaçment per si sols. Partint d'aquesta premissa, aquest treball es divideix en tres apartats. El primer repassa l'evolució del principi de subsidiarietat a la UE des del Tractat de Maastricht. El segon analitza el debat que va tenir lloc a la Convenció Europea voltant d'aquest principi i la proposta final recollida en el projecte de Tractat Constitucional. El tercer i últim estudia les implicacions institucionals que podrien derivar d'aquesta per les regions amb competències legislatives i, en particular, per les Comunitats Autònomes

Antiplasmodial activity of iron(II) and ruthenium(II) organometallic complexes against Plasmodium falciparum blood parasites

This work reports the in vitro activity against Plasmodium falciparumblood forms (W2 clone, chloroquine-resistant) of tamoxifen-based compounds and their ferrocenyl (ferrocifens) and ruthenocenyl (ruthenocifens) derivatives, as well as their cytotoxicity against HepG2 human hepatoma cells. Surprisingly with these series, results indicate that the biological activity of ruthenocifens is better than that of ferrocifens and other tamoxifen-like compounds. The synthesis of a new metal-based compound is also described. It was shown, for the first time, that ruthenocifens are good antiplasmodial prototypes. Further studies will be conducted aiming at a better understanding of their mechanism of action and at obtaining new compounds with better therapeutic profile.
