Nas ltimas dcadas assistimos a transformaes econmicas, tecnolgicas, polticas e sociais, que influenciaram diretamente o modo de pensar e agir nas organizaes. O conceito de competncias, com uma valorizao crescente, surge como uma alternativa abordagem da gesto de recursos humanos por funes, respondendo aos desafios atuais do mercado: necessidade de flexibilidade, de adaptao a mudanas contnuas, exigncias crescentes do mercado e competitividade das organizaes nesse mercado. A rea da sade, e concretamente a profisso de Enfermagem tambm tem evoludo, surgindo em 2009, uma nova forma de operacionalizar a carreira destes profissionais. No que diz respeito aos enfermeiros com funes de gesto, o contedo funcional est descrito, contudo, no existe uma definio clara das competncias requeridas para estes profissionais. Este trabalho de investigao, de cariz exploratrio, utilizando uma metodologia qualitativa, pretendeu propor uma estratgia de definio de um modelo de competncias para os enfermeiros com funes de gesto em Portugal. Para isso, definimos categorias de competncias, atravs da anlise da literatura e da legislao. Seguiu-se a realizao de entrevistas a um painel de doze peritos, e uma anlise de contedo dos dados (categorizao do tipo misto). Procedemos a uma comparao da recolha emprica de competncias com as da recolha terica, e definimos uma lista de 10 competncias para as funes de gesto dos enfermeiros: Competncias Tcnicas de Gesto; Competncias Interpessoais; Comunicao; Gesto de Recursos Humanos; Pensamento Crtico; Conhecimento de Polticas de Sade; Competncias Tcnicas de Enfermagem; Organizao e Planeamento; Trabalho de Equipa; Preocupao pela Qualidade. De forma a complementar o estudo, pretendemos identificar a perceo das lacunas de competncias nos enfermeiros com funes de gesto, e identificar os processos de desenvolvimento de competncias considerados mais relevantes para estes profissionais. As lacunas identificadas nas competncias dos atuais enfermeiros com funes de gesto, face s mais valorizadas, so reduzidas e dispersas, pelo que consideramos pouco significativas. A forma de desenvolvimento de competncias mais valorizado pelo painel de peritos foi a formao (acadmica e em contexto profissional). Foi tambm realada a importncia do empenho individual neste processo, assim como a avaliao de competncias antes dos enfermeiros assumirem funes de gesto.Consideramos que esta investigao traz contributos quer para a literatura da Gesto por Competncias, quer para a literatura da definio de competncias das funes dos enfermeiros com funes de gesto, quer para a profisso de enfermagem, (nomeadamente, para as funes de gesto dos enfermeiros), quer para o prprio SNS, j que faz algumas propostas e sugestes para a evoluo das prticas de gesto de pessoas.

Objective: It has been shown that specific competence is necessary for preventing and managing conflicts in healthcare settings. The aim of this descriptive and correlation study was to investigate and compare the self-reported conflict management competence (CMC) of nursing students who were on the point of graduating (NSPGs), and the CMC of registered nurses (RNs) with professional experience. Methods: The data collection, which consisted of soliciting answers to items measuring CMC in the Nurse Professional Competence (NPC) Scale, was performed as a purposive selection of 11 higher education institutions (HEIs) in Sweden. Three CMC items from the NPC Scale were answered by a total of 569 nursing students who were on the point of graduating and 227 RN registered nurses with professional experience. Results: No significant differences between NSPGs and RNs were found, and both groups showed a similar score pattern, with the lowest score for the item: How do you perceive your ability to develop the group and strengthen competence in conflict management and problem-solving, based on knowledge of group dynamics?. RNs with long professional experience (>24 months) rated their overall CMC as significantly better than RNs with short (<24 months) professional experience did (p = .05). NSPGs who had experience of international studies during their nursing education reported higher CMC, compared with those who did not have this experience (p = .03). RNs who reported a high degree of utilisation of CMC during the previous month scored higher regarding self-reported overall CMC (p < .0001). Conclusions: Experience of international studies during nursing education, or long professional experience, resulted in higher self-reported CMC. Hence, the CMC items in the NPC Scale can be suitable for identifying self-reported conflict management competence among NSPGs and RNs

When using the laryngeal tube and the intubating laryngeal mask airway (ILMA), the medium-size (maximum volume 1100 ml) versus adult (maximum volume 1500 ml) self-inflating bags resulted in significantly lower lung tidal volumes. No gastric inflation occurred when using both devices with either ventilation bag. The newly developed medium-size self-inflating bag may be an option to further reduce the risk of gastric inflation while maintaining sufficient lung ventilation. Both the ILMA and laryngeal tube proved to be valid alternatives for emergency airway management in the experimental model used.

Fatty acid degradation in most organisms occurs primarily via the beta-oxidation cycle. In mammals, beta-oxidation occurs in both mitochondria and peroxisomes, whereas plants and most fungi harbor the beta-oxidation cycle only in the peroxisomes. Although several of the enzymes participating in this pathway in both organelles are similar, some distinct physiological roles have been uncovered. Recent advances in the structural elucidation of numerous mammalian and yeast enzymes involved in beta-oxidation have shed light on the basis of the substrate specificity for several of them. Of particular interest is the structural organization and function of the type 1 and 2 multifunctional enzyme (MFE-1 and MFE-2), two enzymes evolutionarily distant yet catalyzing the same overall enzymatic reactions but via opposite stereochemistry. New data on the physiological roles of the various enzymes participating in beta-oxidation have been gathered through the analysis of knockout mutants in plants, yeast and animals, as well as by the use of polyhydroxyalkanoate synthesis from beta-oxidation intermediates as a tool to study carbon flux through the pathway. In plants, both forward and reverse genetics performed on the model plant Arabidopsis thaliana have revealed novel roles for beta-oxidation in the germination process that is independent of the generation of carbohydrates for growth, as well as in embryo and flower development, and the generation of the phytohormone indole-3-acetic acid and the signal molecule jasmonic acid.

SUMMARYAstrocytes represent the largest cell population in the human brain. In addition to a well established role as metabolic support for neuronal activity, in the last years these cells have been found to accomplish other important and, sometimes, unexpected functions. The tight enwrapping of synapses by astrocytic processes and the predominant expression of glutamate uptake carriers in the astrocytic rather than neuronal plasma membranes brought to the definition of a critical involvement of astrocytes in the clearance of glutamate from synaptic junctions. Moreover, several publications showed that astrocytes are able to release chemical transmitters (gliotransmitters) suggesting their active implication in the control of synaptic functions. Among gliotransmitters, the best characterized is glutamate, which has been proposed to be released from astrocytes in a Ca2+ dependent manner via exocytosis of synaptic-like microvesicles.In my thesis I present results leading to substantial advancement of the understanding of the mechanisms by which astrocytes modulate synaptic activity in the hippocampus, notably at excitatory synapses on dentate granule cells. I show that tumor necrosis factor- alpha (TNFa), a molecule that is generally involved in immune system functions, critically controls astrocyte-to-synapse communication (gliotransmission) in the brain. With constitutive levels of TNFa present, activation of purinergic G protein-coupled receptors in astrocytes, called P2Y1 receptors, induces localized intracellular calcium ([Ca2+]j) elevation in astrocytic processes (measured by two-photon microscopy) followed by glutamate release and activation of pre-synaptic NMDA receptors resulting in synaptic potentiation. In preparations lacking TNFa, astrocytes respond with identical [Ca2+]i elevations but fail to induce neuromodulation. I find that TNFa specifically controls the glutamate release step of gliotransmission. Addition of very low (picomolar) TNFa concentrations to preparations lacking the cytokine, promptly reconstitutes both normal exocytosis in cultured astrocytes and gliotransmission in hippocampal slices. These data provide the first demonstration that gliotransmission and its synaptic effects are controlled not only by astrocyte [Ca2+]i elevations but also by permissive/homeostatic factors like TNFa.In addition, I find that higher and presumably pathological TNFa concentrations do not act just permissively but instead become direct and potent triggers of glutamate release from astrocytes, leading to a strong enhancement of excitatory synaptic activity. The TNFa action, like the one observed upon P2Y1R activation, is mediated by pre-synaptic NMDA receptors, but in this case the effect is long-lasting, and not reversible. Moreover, I report that a necessary molecular target for this action of TNFa is TNFR1, one of the two specific receptors for the cytokine, as I found that TNFa was unable to induce synaptic potentiation when applied in slices from TNFR1 knock-out (Tnfrlv") mice. I then created a double transgenic mouse model where TNFR1 is knocked out in all cells but can be re-expressed selectively in astrocytes and I report that activation of the receptors in these cells is sufficient to reestablish TNFa-dependent long-lasting potentiation of synaptic activity in the TNFR1 knock-out mice.I therefore discovered that TNFa is a primary molecule displaying both permissive and instructive roles on gliotransmission controlling synaptic functions. These reports might have profound implications for the understanding of both physiological and pathological processes associated to TNFa production, including inflammatory processes in the brain.RSUMLes astrocytes sont les cellules les plus abondantes du cerveau humain. Outre leur rle bien tabli dans le support mtabolique de l'activit neuronale, d'autres fonctions importantes, et parfois inattendues de ces cellules ont t mises en lumire au cours de ces dernires annes. Les astrocytes entourent troitement les synapses de leurs fins processus qui expriment fortement les transporteurs du glutamate et permettent ainsi aux astrocytes de jouer un rle critique dans l'limination du glutamate de la fente synaptique. Nanmoins, les astrocytes semblent tre capables de jouer un rle plus intgratif en modulant l'activit synaptique, notamment par la libration de transmetteurs (gliotransmetteurs). Le gliotransmetteur le plus tudi est le glutamate qui est libr par l'exocytose rgule de petites vsicules ressemblant aux vsicules synaptiques (SLMVs) via un mcanisme dpendant du calcium.Les rsultats prsents dans cette thse permettent une avance significative dans la comprhension du mode de communication de ces cellules et de leur implication dans la transmission de l'information synaptique dans l'hippocampe, notamment des synapses excitatrices des cellules granulaires du gyrus dentel. J'ai pu montrer que le facteur de ncrose tumorale alpha (TNFa), une cytokine communment associe au systme immunitaire, est aussi fondamentale pour la communication entre astrocyte et synapse. Lorsqu'un niveau constitutif trs bas de TNFa est prsent, l'activation des rcepteurs purinergiques P2Y1 (des rcepteurs coupls protine G) produit une augmentation locale de calcium (mesure en microscopie bi-photonique) dans l'astrocyte. Cette dernire dclenche ensuite une libration de glutamate par les astrocytes conduisant l'activation de rcepteurs NMDA prsynaptiques et une augmentation de l'activit synaptique. En revanche, dans la souris TNFa knock-out cette modulation de l'activit synaptique par les astrocytes n'est pas bien qu'ils prsentent toujours une excitabilit calcique normale. Nous avons dmontr que le TNFa contrle spcifiquement l'exocytose rgule des SLMVs astrocytaires en permettant la fusion synchrone de ces vsicules et la libration de glutamate destination des rcepteurs neuronaux. Ainsi, nous avons, pour la premire fois, prouv que la modulation de l'activit synaptique par l'astrocyte ncessite, pour fonctionner correctement, des facteurs permissifs comme le TNFa, agissant sur le mode de scrtion du glutamate astrocytaire.J'ai pu, en outre, dmontrer que le TNFa, des concentrations plus leves (celles que l'on peut observer lors de conditions pathologiques) provoque une trs forte augmentation de l'activit synaptique, agissant non plus comme simple facteur permissif mais bien comme dclencheur de la gliotransmission. Le TNFa provoque 1'activation des rcepteurs NMD A pr-synaptiques (comme dans le cas des P2Y1R) mais son effet est long terme et irrversible. J'ai dcouvert que le TNFa active le rcepteur TNFR1, un des deux rcepteurs spcifiques pour le TNFa. Ainsi, l'application de cette cytokine sur une tranche de cerveau de souris TNFR1 knock-out ne produit aucune modification de l'activit synaptique. Pour vrifier l'implication des astrocytes dans ce processus, j'ai ensuite mis au point un modle animal doublement transgnique qui exprime le TNFR1 uniquement dans les astrocytes. Ce dernier m'a permis de prouver que l'activation des rcepteurs TNFR1 astrocytaires est suffisante pour induire une augmentation de l'activit synaptique de manire durable.Nous avons donc dcouvert que le TNFa possde un double rle, la fois un rle permissif et actif, dans le contrle de la gliotransmission et, par consquent, dans la modulation de l'activit synaptique. Cette dcouverte peut potentiellement tre d'une extrme importance pour la comprhension des mcanismes physiologiques et pathologiques associs la production du TNFa, en particulier lors de conditions inflammatoires.RSUM GRAND PUBLICLes astrocytes reprsentent la population la plus nombreuse de cellules dans le cerveau humain. On sait, nanmoins, trs peu de choses sur leurs fonctions. Pendant trs longtemps, les astrocytes ont uniquement t considrs comme la colle du cerveau, un substrat inerte permettant seulement de lier les cellules neuronales entre elles. Il n'y a que depuis peu que l'on a dcouvert de nouvelles implications de ces cellules dans le fonctionnement crbral, comme, entre autres, une fonction de support mtabolique de l'activit neuronale et un rle dans la modulation de la neurotransmission. C'est ce dernier aspect qui fait l'objet de mon projet de thse.Nous avons dcouvert que l'activit des synapses (rgions qui permettent la communication d'un neurone un autre) qui peut tre potentialise par la libration du glutamate par les astrocytes, ne peut l'tre que dans des conditions astrocytaires trs particulires. Nous avons, en particulier, identifi une molcule, le facteur de ncrose tumorale alpha (TNFa) qui joue un rle critique dans cette libration de glutamate astrocytaire.Le TNFa est surtout connu pour son rle dans le systme immunitaire et le fait qu'il est massivement libr lors de processus inflammatoires. Nous avons dcouvert qu'en concentration minime, correspondant sa concentration basale, le TNFa peut nanmoins exercer un rle indispensable en permettant la communication entre l'astrocyte et le neurone. Ce mode de fonctionnement est assez probablement reprsentatif d'un processus physiologique qui permet d'intgrer la communication astrocyte/neurone au fonctionnement gnral du cerveau. Par ailleurs, nous avons galement dmontr qu'en quantit plus importante, le TNFa change son mode de fonctionnement et agit comme un stimulateur direct de la libration de glutamate par l'astrocyte et induit une activation persistante de l'activit synaptique. Ce mode de fonctionnement est assez probablement reprsentatif d'un processus pathologique.Nous sommes galement arrivs ces conclusions grce la mise en place d'une nouvelle souche de souris doublement transgniques dans lesquelles seuls les astrocytes (etnon les neurones ou les autres cellules crbrales) sont capables d'tre activs par le TNFa.

Receiver functions from small local earthquakes were used to determine sediment thicknesses in Porto dos Gauchos seismic zone (PGSZ), Parecis basin, Amazonian craton, Brazil. The high velocity contrast between basement and sediments (P-wave velocities of 6.1 and 3.0 km/s, respectively) favors the generation of clear P-to-S converted phases (Ps) seen in the radial component, and also S-to-P conversions (Sp) seen in the vertical component. A reference 10 velocity model determined with shallow refraction experiment in PGSZ helped to convert Ps P time differences to basement depths at 15 stations deployed for aftershocks studies. The results of receiver function integrated with the shallow refraction reveal that the basement depths in the PGSZ increases from the basin border in the north up to about 600 m depth in the south. The basement topography, however, does not vary smoothly and a basement high with a steep topography was detected near the epicentral area. A 400 m elevation difference within 1.7 km distance suggests a possible border fault of a buried graben. This feature seems to be oriented roughly WSW-ENE and could indicate basement structures related to the seismicity of the Porto dos Gauchos Seismic Zone. (C) 2011 Elsevier Ltd. All rights reserved.

In [H. Brezis, A. Friedman, Nonlinear parabolic equations involving measures as initial conditions, J. Math. Pure Appl. (9) (1983) 73-97.] Brezis and Friedman prove that certain nonlinear parabolic equations, with the delta-measure as initial data, have no solution. However in [J.F. Colombeau, M. Langlais, Generalized solutions of nonlinear parabolic equations with distributions as initial conditions, J. Math. Anal. Appl (1990) 186-196.] Colombeau and Langlais prove that these equations have a unique solution even if the delta-measure is substituted by any Colombeau generalized function of compact support. Here we generalize Colombeau and Langlais` result proving that we may take any generalized function as the initial data. Our approach relies on recent algebraic and topological developments of the theory of Colombeau generalized functions and results from [J. Aragona, Colombeau generalized functions on quasi-regular sets, Publ. Math. Debrecen (2006) 371-399.]. (C) 2009 Elsevier Ltd. All rights reserved.

Medulloblastoma (MB) is the most common malignant brain tumor in children. It is known that overexpression and/or amplification of the MYC oncogene is associated with poor clinical outcome, but the molecular mechanisms and the MYC downstream effectors in MB remain still elusive. Besides contributing to elucidate how progression of MB takes place, most importantly, the identification of novel MYC-target genes will suggest novel candidates for targeted therapy in MB. A group of 209 MYC-responsive genes was obtained from a complementary DNA microarray analysis of a MB-derived cell line, following MYC overexpression and silencing. Among the MYC-responsive genes, we identified the members of the bone morphogenetic protein (BMP) signaling pathway, which have a crucial role during the development of the cerebellum. In particular, the gene BMP7 was identified as a direct target of MYC. A positive correlation between MYC and BMP7 expression was documented by analyzing two distinct sets of primary MB samples. Functional studies in vitro using a small-molecule inhibitor of the BMP/SMAD signaling pathway reproduced the effect of the small interfering RNA-mediated silencing of BMP7. Both approaches led to a block of proliferation in a panel of MB cells and to inhibition of SMAD phosphorylation. Altogether, our findings indicate that high MYC levels drive BMP7 overexpression, promoting cell survival in MB cells. This observation suggests the potential relevance of targeting the BMP/SMAD pathway as a novel therapeutic approach for the treatment of childhood MB.

In e+e event shapes studies at LEP, two different measurements were sometimes performed: a calorimetric measurement using both charged and neutral particles and a track-based measurement using just charged particles. Whereas calorimetric measurements are infrared and collinear safe, and therefore calculable in perturbative QCD, track-based measurements necessarily depend on nonperturbative hadronization effects. On the other hand, track-based measurements typically have smaller experimental uncertainties. In this paper, we present the first calculation of the event shape track thrust and compare to measurements performed at ALEPH and DELPHI. This calculation is made possible through the recently developed formalism of track functions, which are nonperturbative objects describing how energetic partons fragment into charged hadrons. By incorporating track functions into soft-collinear effective theory, we calculate the distribution for track thrust with next-to-leading logarithmic resummation. Due to a partial cancellation between nonperturbative parameters, the distributions for calorimeter thrust and track thrust are remarkably similar, a feature also seen in LEP data.
