A comunicação do programa de valorização turística "Allgarve", da responsabilidade da Entidade Regional de Turismo do Algarve

A valorização e diferenciação de um destino turístico passa pela capacidade em se distinguir dos destinos concorrentes através da oferta diversificada de experiências relevantes que marquem quem o visita. Foi precisamente sob este mote: “experiências que marcam” que surgiu em 2007 o programa de eventos ALLGARVE, cujo principal objetivo foi a criação de um conjunto de eventos culturais, desportivos e de animação que atraíssem turistas e visitantes em busca de experiências mais enriquecedoras, abrangentes, dinâmicas e sofisticadas no seu período de férias. Este programa foi uma iniciativa do Ministério da Economia e Inovação (MEI), desenvolvido através do Turismo de Portugal (TP), em estreita articulação com a Entidade Regional de Turismo (ERTA), que assumiu um papel fundamental de parceira e interlocutora na prossecução do mesmo, tendo a Divisão de Marketing (posteriormente Equipa Multidisciplinar de Comunicação e Imagem – EMCI) desta entidade assumido um papel de enorme relevância durante esse período. Uma das principais áreas de intervenção do programa ALLGARVE foi ao nível da comunicação, uma vez que se pretendia, acima de tudo, criar uma marca, dar-lhe notoriedade e credibilidade e fazer com que turistas, visitantes e residentes se identificassem com a mesma. Para tal foi necessário o estabelecimento de um plano de comunicação vasto que abrangesse meios variados, de forma a atingir os públicos-alvo em larga escala. Nesta perspetiva, uma grande fatia do orçamento global do programa foi canalizada para vagas de comunicação através de publicidade em imprensa escrita, outdoors, rádio, televisão, internet e outros meios alternativos, ações de relações públicas (RP) junto dos mercados-alvo e do trade, e a produção de todas as peças de comunicação necessárias ao acompanhamento dos eventos (catálogos, faixas, brindes, entre outros). O presente relatório de atividade profissional pretende assim dar a conhecer o plano de comunicação do programa ALLGARVE, a sua caracterização e contributo para a valorização turística do destino Algarve, devidamente enquadrado na importância da comunicação e dos eventos no Marketing de Áreas Destino.

Development of a Piggybac based direct reprogramming system for derivation of integration free induced pluripotent stem cells

Induced pluripotent stem cells (iPSc) have great potential for applications in regenerative medicine, disease modeling and basic research. Several methods have been developed for their derivation. The original method of Takahashi and Yamanaka involved the use of retroviral vectors which result in insertional mutagenesis, presence in the genome of potential oncogenes and effects of residual transgene expression on differentiation bias of each particular iPSc line. Other methods have been developed, using different viral vectors (adenovirus and Sendai virus), transient plasmid transfection, mRNA transduction, protein transduction and use of small molecules. However, these methods suffer from low efficiencies; can be extremely labor intensive, or both. An additional method makes use of the piggybac transposon, which has the advantage of inserting its payload into the host genome and being perfectly excised upon re-expression of the transposon transposase. Briefly, a policistronic cassette expressing Oct4, Sox2, Klf4 and C-Myc flanked by piggybac terminal repeats is delivered to the cells along with a plasmid transiently expressing piggybac transposase. Once reprogramming occurs, the cells are re-transfected with transposase and subclones free of tranposon integrations screened for. The procedure is therefore very labor intensive, requiring multiple manipulations and successive rounds of cloning and screening. The original method for reprogramming with the the PiggyBac transposon was created by Woltjen et al in 2009 (schematized here) and describes a process with which it is possible to obtain insert-free iPSc. Insert-free iPSc enables the establishment of better cellular models of iPS and adds a new level of security to the use of these cells in regenerative medicine. Due to the fact that it was based on several low efficiency steps, the overall efficiency of the method is very low (<1%). Moreover, the stochastic transfection, integration, excision and the inexistence of an active way of selection leaves this method in need of extensive characterization and screening of the final clones. In this work we aime to develop a non-integrative iPSc derivation system in which integration and excision of the transgenes can be controlled by simple media manipulations, avoiding labor intensive and potentially mutagenic procedures. To reach our goal we developed a two vector system which is simultaneously delivered to original population of fibroblasts. The first vector, Remo I, carries the reprogramming cassette and GFP under the regulation of a constitutive promoter (CAG). The second vector, Eneas, carries the piggybac transposase associated with an estrogen receptor fragment (ERT2), regulated in a TET-OFF fashion, and its equivalent reverse trans-activator associated with a positive-negative selection cassette under a constitutive promoter. We tested its functionality in HEK 293T cells. The protocol is divided in two the following steps: 1) Obtaining acceptable transfection efficiency into human fibroblasts. 2) Testing the functionality of the construct 3) Determining the ideal concentration of DOX for repressing mPB-ERT2 expression 4) Determining the ideal concentration of TM for transposition into the genome 5) Determining the ideal Windows of no DOX/TM pulse for transposition into the genome 6) 3, 4 and 5) for transposition out of the genome 7) Determination of the ideal concentration of GCV for negative selection We successfully demonstrated that ENEAS behaved as expected in terms of DOX regulation of the expression of mPB-ERT2. We also demonstrated that by delivering the plasmid into 293T HEK cells and manipulating the levels of DOX and TM in the medium, we could obtain puromycin resistant lines. The number of puromycin resistant colonies obtained was significantly higher when DOX as absent, suggesting that the colonies resulted from transposition events. Presence of TM added an extra layer of regulation, albeit weaker. Our PCR analysis, while not a clean as would be desired, suggested that transposition was indeed occurring, although a background level of random integration could not be ruled out. Finally, our attempt to determine whether we could use GVC to select clones that had successfully mobilized PB out of the genome was unsuccessful. Unexpectedly, 293T HEK cells that had been transfected with ENEAS and selected for puromycin resistance were insensitive to GCV.

On the solvation in lipid bilayers measured by pyrene fluorescence: thermal and molecular composition influence on equivalent polarity in lipidic mixtures

Phosphatidylcholine (PC), sphingomyelin (SM) and cholesterol (CHOL) are major constituents of mammalian cell membranes. DPPC/CHOL and DPPC/DMPC are well-known binary mixtures. POPC/CHOL, DOPC/CHOL, egg-SM/CHOL, egg-SM/POPC and egg-SM/DOPC are less studied, but also important for the comprehension of the POPC/egg-SM/CHOL mixtures. These provide complex media for which polarity is hard to access. It is mainly determined by the water penetrating the bilayer (unevenly distributed creating a polarity gradient), though the influence of the dipoles from phospholipids (e.g. –PO, –CO, –OH) and the double bond in the steroid ring of CHOL cannot be neglected. CHOL derivatives are an interesting tool to verify the influence of the double bonds in the polarization of its surroundings. Pyrene fluorescence was used to access an equivalent polarity (associated to the dielectric constant) near the lipid/water interface of lipid bilayers. POPC/CHOL and DOPC/CHOL have similar thermal behavior and variation with CHOL content, though for lower CHOL content the equivalent polarity is higher for the DOPC/CHOL mixtures. The studies with DPPC and DMPC showed that pyrene does not seem to have a marked preference for either ordered or disordered phases. For DPPC/CHOL and egg-SM/CHOL the highlight goes to the behavior of the mixtures at higher CHOL amounts, where there is a substantial change in the thermal behavior and polarity values especially for the egg-SM/CHOL mixture. Egg-SM/POPC and egg-SM/DOPC show different behavior depending on which phospholipid has a higher molar proportion. The ternary mixtures analyzed do not exhibit significant differences, though there is the indication of the existence of a more ordered environment at lower temperatures and a less ordered environment for higher temperatures. The presence of 7DHC or DCHOL in egg-SM bilayers showed a tendency for the same behavior detected upon mixing higher amounts of CHOL.

Du roman au théâtre: adaptations théâtrales dans la dramaturgie franco-portugaise au XIXe siècle

L’adaptation de romans à la scène au XIXe siècle dans la dramaturgie franco-portugaise passe par l’étude des relations et des contaminations intergénériques et interculturelles qui s’établissent entre les genres romanesque et dramatique dans les deux cultures. Pour ce faire, nous nous sommes consacrés dans une première partie aux questions théoriques qu’un tel exercice soulève. Effectivement, nous ne pourrions pas prétendre étudier et cerner un tel phénomène littéraire et artistique sans un abordage pluridimensionnel qui nous mène vers son approche à la lumière des études de Traduction et de Réception, d’un côté et, de l’autre, des études sociologiques. Questionner les fondements théoriques de l’adaptation théâtrale, sa production et sa circulation dans les deux pays supposait, pour nous, dès le départ, délimiter non seulement l’horizon d’attente d’une telle pratique artistique mais aussi sa place et son impact dans le champ littéraire et le polysystème culturel de l’époque. En contrepoint, nous nous sommes ensuite intéressés à la question de l’adaptation théâtrale et des contact zones, cette fois en passant par la problématique de la transculturation qu’engendre le contact de deux littératures différentes, s’affrontant dans le champ culturel et littéraire d’arrivée. Dans une deuxième partie, nous nous sommes concentrés sur la contextualisation historico-générique de l’adaptation théâtrale. Le recours à la transposition scénique de romans révèle un désir de gloire au niveau financier et artistique. La pratique est courante, voire généralisée dans le champ littéraire français du XIXe siècle. Parmi les adeptes de l’exercice de transposition, Dumas père est certainement l’auteur le plus prolifique. En outre, la transmodalisation générique s’insère dans un mouvement de création collective, puisque la collaboration entre auteurs dramatiques est très répandue. Par la suite, nous nous sommes intéressés à la genèse des textes à travers la transmodalisation du roman au théâtre : du roman-feuilleton au roman naturaliste. Nous avons constaté que le genre romanesque comme le genre dramatique sont empreints de contaminations intergénériques qui passent par la théâtralisation du roman puis par la romanisation du théâtre. Ainsi, l’adaptation apparaît comme la concrétisation de la fusion des genres romanesque et dramatique qui donnent lieu à un genre hybride. L’adaptation est alors le résultat d’une série de procédés et de techniques : la transmodalisation du roman s’adapte aux nécessités génériques du théâtre. De la sorte, nous avons distingué cinq types d’adaptations : l’adaptation fidèle, l’adaptation partielle, l’adaptation libre, l’adaptation pastichée et l’adaptation de l’adaptation. Dans une troisième partie, nous avons abordé le phénomène de l’adaptation dans le contexte littéraire portugais au XIXe siècle. À travers la présence accrue du théâtre français sur les scènes lisboètes, nous avons observé les rouages de la transposition d’un modèle étranger qui peut passer par différents processus, comme la traduction ou l’appropriation par l’adaptation théâtrale. Cela nous a amené à présenter cinq modèles d’adaptations théâtrales issues d’hypotextes français : l’adaptation française, la traduction fidèle de l’adaptation française, la traduction libre de l’adaptation française, l’adaptation à la couleur locale de l’adaptation française et l’adaptation portugaise d’un roman français. Nous avons également présenté quelques exemples de cas concrets, notamment Le Comte de Monte-Cristo adapté au répertoire lisboète. L’étude de ce phénomène culturel nous a permis de mieux cerner son impact sur le champ théâtral lisboète du XIXe siècle, dans la mesure où il contribue à la transculturation de la dramaturgie portugaise de l’époque.

Projecto execução: parque urbano da Vila de Ourique

O projeto do parque da Vila de Ourique, na Freguesia de Ourique, Concelho de Ourique, foi desenvolvido com o objetivo de dar resposta a um conjunto de necessidades indicadas pela Câmara Municipal, desenvolvendo-se este ao nível de projeto execução. O trabalho foi desenvolvido em duas partes, inicialmente foi desenvolvida a análise que teve como objetivo perceber e identificar pontos positivos e aspetos a serem trabalhos e melhorados na área de intervenção. A segunda parte do trabalho incidiu sobre a parte prática ao nível dos processos formais e materiais, dando resposta às necessidades do programa pretendido pelo cliente. O projeto desenvolve-se numa área em que o próprio PDM de Ourique já prevê a criação de espaços verdes equipados. O facto da sua localização ser adjacente à Vila faz com que tenha uma grande proximidade com a população. A área do projeto encontra-se muito descaracterizada pelo facto de terem sido efetuados grandes movimentos de terras, que, alterando a morfologia original, culminaram na criação de dois patamares. A proposta dá resposta a um conjunto necessidades e equipamentos pretendidos pelo cliente e promove a criação de um espaço atrativo com várias funcionalidades e espaços que se adaptam a vários usos. O projeto integra vários equipamentos desportivos já existentes ou previstos tais como, campo de futebol, campos de ténis, pista de manutenção, piscinas e parque de estacionamento. Pretende-se, que o espaço assegure as necessidades de recreio e lazer da população, bem como funções ecológicas e estéticas de uma forma sustentável, melhorando a qualidade ambiental e a qualidade de vida da população.

Evolution, gene regulation and functional analysis of BMP2 in fish

Bone morphogenetic proteins (BMPs) are multifunctional growth factors belonging to the transforming growth factor β (TGFβ) superfamily with a central role in bone formation and mineralization. BMP2, a founding member of this family, has demonstrated remarkable osteogenic properties and is clinically used to promote bone repair and fracture healing. Lack of basic data on factors regulating BMP2 expression and activity have hampered a better understanding of its role in bone formation and bone-related diseases. The objective of this work was to collect new functional data and determine spatiotemporal expression patterns in a fish system aiming towards a better understanding of BMP2 function and regulation. Transcriptional and post-transcriptional regulation of gilthead seabream BMP2 gene was inferred from luciferase reporter systems. Several bone- and cartilage-related transcription factors (e.g. RUNX3, MEF2c, SOX9 and ETS1) were found to regulate BMP2 transcription, while microRNA 20a was shown to affect stability of the BMP2 transcript and thus the mineralogenic capacity of fish bone-derived host cells. The regulation of BMP2 activity through an interaction with the matrix Gla protein (MGP) was investigated in vitro using BMP responsive elements (BRE) coupled to luciferase reporter gene. Although we demonstrated the functionality of the experimental system in a fish cell line and the activation of BMP signaling pathway by seabream BMP2, no conclusive evidence could be collected on a possible interaction beween MGP and BMP2. The evolutionary relationship among the members of BMP2/4/16 subfamily was inferred from taxonomic and phylogenetic analyses. BMP16 diverged prior to BMP2 and BMP4 and should be the result of an ancient genome duplication that occurred early in vertebrate evolution. Structural and functional data suggested that all three proteins are effectors of the BMP signaling pathway, but expression data revealed different spatiotemporal patterns in teleost fish suggesting distinct mechanisms of regulation. In this work, through the collection of novel data, we provide additional insight into the regulation, the structure and the phylogenetic relationship of BMP2 and its closely related family members.

Identification of novel molecular determinants of tissue mineralization in fish

The identification of genes involved in signaling and regulatory pathways, and matrix formation is paramount to the better understanding of the complex mechanisms of bone formation and mineralization, and critical to the successful development of therapies for human skeletal disorders. To achieve this objective, in vitro cell systems derived from skeletal tissues and able to mineralize their extracellular matrix have been used to identify genes differentially expressed during mineralization and possibly new markers of bone and cartilage homeostasis. Using cell systems of fish origin and techniques such as suppression subtractive hybridization and microarray hybridization, three genes never associated with mechanisms of calcification were identified: the calcium binding protein S100-like, the short-chain dehydrogenase/reductase sdr-like and the betaine homocysteine S-methyltransferase bhmt3. Analysis of the spatial-temporal expression of these 3 genes by qPCR and in situ hybridization revealed: (1) the up-regulation of sdr-like transcript during in vitro mineralization of gilthead seabream cell lines and its specificity for calcified tissues and differentiating osteoblasts; (2) the up-regulation of S100-like and the down-regulation of bhmt3 during in vitro mineralization and the central role of both genes in cartilaginous tissues undergoing endo/perichondral mineralization in juvenile fish. While expression of S100-like and bhmt3 was restricted to calcified tissues, sdr-like transcript was also detected in soft tissues, in particular in tissues of the gastrointestinal tract. Functional analysis of gene promoters revealed the transcriptional regulation of the 3 genes by known regulators of osteoblast and chondrocyte differentiation/mineralization: RUNX2 and RAR (sdr-like), ETS1 (s100-like; bhmt3), SP1 and MEF2c (bhmt3). The evolutionary relationship of the different orthologs and paralogs identified within the scope of this work was also inferred from taxonomic and phylogenetic analyses and revealed novel protein subfamilies (S100-like and Sdr-like) and the explosive diversity of Bhmt family in particular fish groups (Neoteleostei). Altogether our results contribute with new data on SDR, S100 and BHMT proteins, evidencing for the first time the role for these three proteins in mechanisms of mineralization in fish and emphasized their potential as markers of mineralizing cartilage and bone in developing fish.
