Texto completoThe ability to process and identify facial emotions are essential factors for an individual\'s social interaction. Some psychiatric disorders can limit an individual\'s ability to recognize emotions in facial expressions. This problem could be confronted by using computational techniques in order to develop learning environments for diagnosis, evaluation, and training in identifying facial emotions. With this motivation, the objective of this work is to define, implement and evaluate a method to synthesize realistic facial expression that represents emotions in images of real people. The main idea of the studies found in the literature is that a facial expression of one persons image can be reenacted in an another persons image. The study differs from the approaches presented in the literature when proposing a technique that considers the similarity between facial images to choose the one that will be used as the origin for reenactment. As a result, we intend to increase the realism of the synthesized images. Our approach to solve the problem, besides searching for the most similar facial components in the image dataset, also deforms the facial elements and maps the differences of illumination in the target image. A visual analysis showed that the images synthesized on the basis of similar faces presented an adequate degree of realism, especially when compared with images synthesized from random faces. The study will contribute to the generation of the images applied to tools for the diagnosis and therapy of psychiatric disorders, and also contribute to the computational field, through the proposition of new techniques for facial expression synthesis

Resumo: Os mecanismos moleculares envolvidos na origem do adenocarcinoma de cólon esporádico (ACE) ainda não estão completamente elucidados. Recentemente, o método da análise seriada da expressão gênica (SAGE) foi descrito como eficaz para identificar a expressão total de genes de tipos celulares diversos, mas esta análise não foi realizada em células epiteliais purificadas do ACE moderadamente diferenciado. Nós caracterizamos pelo método SAGE a expressão gênica total de células epiteliais neoplásicas do cólon de um paciente com ACE moderadamente diferenciado (SAGE CC) e de células epiteliais normais do cólon de um paciente com megacólon chagásico (SAGE CN). Foram geradas, após o seqüenciamento automático, 44.004 e 43.570 tags totais das bibliotecas SAGE CC e SAGE CN, representando 16.484 e 13.479 tags únicas, respectivamente. Na comparação entre as bibliotecas, 171 transcritos diferencialmente expressos foram identificados (P< 0,001; expressão diferencial = 5), incluindo 10% de transcritos que podem representar genes não descritos. As expressões de 10 genes diferencialmente expressos foram quantificadas pela reação em cadeia da polimerase em tempo real (qPCR) na amostra de células epiteliais neoplásicas (SAGE CC), com o intuito de validar os resultados obtidos pelo SAGE, e, posteriormente, em amostras de células epiteliais de outros cinco pacientes com o mesmo tipo de doença. As expressões foram concordantes em 80% dos genes (CEACAM6, KLK6, LYZ, PFN1, S100A8, S100A9, VIL2 e ZFHX1B) e discordantes nos demais 20% (PLA1A e ZNF277). As expressões dos genes de interesse, quantificadas pelos dois métodos, foram similares na amostra SAGE CC e nas amostras dos demais pacientes com a doença. Foram observadas expressões anormais de genes envolvidos com a proliferação e diferenciação celular e com a resposta ao stress em células epiteliais neoplásicas. Foram também visualizadas expressões anormais de genes não relacionados com a doença e de genes ainda não identificados. Em conjunto, os nossos resultados podem contribuir para a identificação de genes relacionados com a origem ou a progressão do ACE moderadamente diferenciado e, ainda, para a descoberta de agentes terapêuticos específicos que controlem a proliferação anormal das células neoplásicas.
Abstract: The molecular mechanisms involved in sporadic colon adenocarcinoma (SCA) are still not completely elucidated. Recently, the serial analysis of gene expression (SAGE) method has allowed the global analysis of genes expressed in diverse cellular types but there are no studies in purified epithelial cells of SCA moderately differenciated. We have characterized through SAGE the global gene expression of neoplastic epithelial cells from a SCA moderately differenciated patient (SAGE CC) and normal epithelial cells from a megacolon patient (SAGE CN). After automatic sequencing, a total of 44.004 tags from SAGE CC and 43.570 tags from SAGE CN profiles were generated, representing 16.484 and 13.479 unique tags, respectively. Comparing both profiles, 171 differentially expressed transcripts were identified (P< 0.001; fold = 5), including 10.0% that may represent novel transcripts. The expression of 10 selected genes was further investigated by realtime polymerase chain reaction (qPCR) in the SCA moderately differenciated epithelial cells sample (SAGE CC), with the purpose of to validate the results obtained by the SAGE method, and also in five epithelial cells samples from the same type of SCA patients. Similar expressions were seen in 80% (CEACAM6, KLK6, LYZ, PFN1, S100A8, S100A9, VIL2 e ZFHX1B) and discordant expressions were seen in 20% (PLA1A e ZNF277) of analysed genes. On SAGE CC sample and samples of the SCA patients, all genes presented similar expressions measured by both methods. We observed abnormal expression of genes involved with cell proliferation and differentiation, and with response to stress in neoplastic epithelial cells. Also, were found abnormal expressions of genes not related with the disease and not identified genes. Together, our results may contribute for the identification of genes involved in the origin or progression of SCA moderately differenciated, as well as for the discovery of new therapeutical agents, with specific action on abnormal proliferation of the neoplastic cells.

Texto completoPrior research showing that children recognize emotional expressions has used a choice-from-array style task; for example, children are asked to find the fear face in an array of several expressions. However, these choice-from-array tasks allow for the use of a process of elimination strategy in which children could select an expression they are unfamiliar with when presented a label that does not apply to other expressions in the array. Across six studies (N = 144), 80% of 2- to 4-year-olds selected a novel expression when presented a target label and performed similarly when the label was novel (such as pax) or familiar (such as fear). In addition, 46% of children went on to freely label the expression with the target label in a subsequent task. These data are the first to show that children extend the process of elimination strategy to facial expressions and also call into question the findings of prior choice-from-array studies

Texto completoA variety of antitumoral agents is capable of inducing DNA damage and eliciting cell cycle arrest, DNA repair or apoptotic responses. The initial response is a cell cycle arrest in an attempt to repair the DNA damage, but under conditions of extensive DNA lesions and high drug cytotoxicity, a signaling cascade triggers alternative mechanisms that inhibit cell proliferation and activate cell death pathways. Astrocytomas are the most common neoplasm of the central nervous system, comprising more than 60% of primary brain tumors. The standard treatment for theses tumors are radiotherapy followed by chemotherapy, however, the prognostic for these patients is still very discouraging. Cisplatin is an efficient DNA-damaging antitumor agent employed for the treatment of various human cancers, including gliomas. This drug binds to DNA, producing diverse types of adducts, which can block replication, transcription, and lead to apoptosis induction. In the present work, we analyzed cellular responses to treatments with the anticancer agent cisplatin in MRC-5 (normal human fibroblasts SV40 transformed) and U343 MG-a (glioma cell line). The responses were evaluated in terms of cell survival, apoptosis induction and profiles of gene expression by the cDNA microarrays method (only for U343 cell line). Cisplatin treatment resulted in a pronounced reduction in MRC-5 cell survival (~ 1%) and U343 (< 1%) after five days of treatment (cell survival test) with several concentrations of cisplatin, ranging from 12.5 to 300 ?M. Following 24h of treatment under similar cisplatin concentrations the survival was reduced at about 20-80% (cytotoxicity test). Both cell lines underwent apoptosis after treatment with different concentrations of cisplatin (12.5; 25 and 50 ?M), but U343 cells presented a maximal frequency of 20.4% apoptosis (25 ?M cisplatin treatment for 72h), while MRC-5 cells presented 11.0% (50 ?M cisplatin treatment for 48h). Analysis of gene expression performed for U343 cells treated with 25 ?M cisplatin for 48h showed several genes that were found significantly (p ? 0,05) down-regulated, most of them related with cytoskeleton alterations (TBCD, RHOA, LIMK2 and MARK1), apoptosis or cell survival (BCL2-XL, ING1, RHOA, VDP, TIMP2, DYRK3 and NFKBIE), cell invasion or metastasis (LIMK2, TIMP2 and CALU), DNA repair (SMC1L1), and cell metabolism (DYRK3, MARK1, TBCD, LIMK2, VDP and P4HB), among others. As a whole, these data demonstrate a serious commitment of the cell machinery after cisplatin-induced cellular damage. About 20% of the cell death corresponds to apoptosis, as was showed by the present assays. However, most of the cells are eliminated by the action of the drug in various levels of the metabolism and maintenance of cell integrity, due to the elevated degree of cisplatin citotoxicity, as demonstrated in cell survival tests.

Texto completoThe diapause is broadly distributed among the arthropods and has had an important role for the evolutionary success of the Class Insecta, mainly because this process permits insects to explore adverse conditions, such as cold and dry seasons. It is known that there are many genes being silenced and others being uniquely expressed during diapause. And although there are evidences that the diapause process has remained conserved during the evolution of species, it is still not clear how conserved are the metabolic patterns involved in this behavior. Tetrapedia diversipes is a solitary bee and a good model to study diapause. Individuals from the first generation do not enter in diapause and develop faster than individuals from the second generation, which enter in diapause during the winter. Moreover, this species is easy to capture in natural conditions due to the high rate of nesting in trap nests. The aim of this work was to compare the gene expression profile among non-diapause larvae from first and second generation (about to enter diapause) and larvae already in diapause, trough transcriptome data. One hundred ninety-four genes were identified as differentially expressed and 87 of them were annotated. Many of these genes have already been described as related to diapause in others species, but the expression pattern was not conserved. These genes were divided in five groups: related to cellular detoxification, cuticle and cytoskeleton, lipids and steroids metabolism, cell cycle and other genes related to diapause

Texto completoIn addition to eubacterial-like multi-subunit RNA polymerases (RNAP) localized in plastids and the nucleus, Arabidopsis thaliana contains three phage-like single-unit, nuclear-encoded, organellar RNAPs. The enzymes RpoTp and RpoTm are imported into plastids and mitochondria, respectively, whereas RpoTmp shows dual targeting properties into both organelles. To investigate if expression of the RpoT genes is light-dependent, light-induced transcript accumulation of RpoTm, RpoTp and RpoTmp was analyzed using quantitative real-time-PCR in 7-day-old seedlings as well as in 3- and 9-week-old rosette leaves. To address the question whether RpoT transcript accumulation is regulated differentially during plant development transcript abundance was measured during leaf development. Additionally, effects of the plants circadian rhythm on RpoT transcript accumulation were analyzed. Transcripts of all three RpoT genes were found to be strongly light-induced even in senescent leaves and only marginally influenced by the circadian clock. Further analyses employing different photoreceptor mutants and light qualities revealed the involvement of multiple receptors in the light-induction process. The biogenesis of mitochondria and chloroplasts as well as processes like respiration and photosynthesis require the activity of genes residing in at least two distinct genomes. There have to be ways of intracellular communication between different genomes to control gene activities in response to developmental and metabolic needs of the plant. In this study, it was shown that gene copy numbers drastically increased in photosynthetically inactive Arabidopsis seedlings. Mitochondrial DNA contents in cotyledons and leaves ranging in age from 2-day-old cotyledons to 37-day-old senescent rosette leaves were examined. A common increase in senescing rosette leaves and drastic differences between individual genes were found, revealing the importance of an integrative chondriome in higher plant cells.

Texto completoRabies is a anthropozoonosis and causes the death of 55,000 people worldwide each year. In this work we used a genetic system derived from the Semliki forest virus (SFV) carrying RNA for gene expression of the rabies virus glycoprotein (RVGP) and green fluorescent protein (GFP), by way of experiment control. Plots of viral particles of SFV-RVGP and SFV-GFP were obtained in BHK-21 cells and quantified by qRT-PCR. Infection assays were performed both with activated and not activated in two virus strains of murine macrophages IC-21 and J774A-1. The expression of RVGP protein was assessed by indirect immunofluorescence test (IFI) and the expression of GFP protein analyzed by fluorescence microscopy and flow cytometry in both strains. The SFV entry of viruses into mammalian cells occurs after 2 hours of infection and according to the experiment in which we analyzed the viral titer of the cell supernatant showed that by 72 hours post-infection viral titer remained at the same initial value, suggesting no entry of virus into the cell by transduction or by phagocytosis.

Esta pesquisa trata de duas diferentes expressões da Arte, a poética e a plástica. Tem como referência principal a obra Arte em Exposição de Carlos Drummond de Andrade, a qual é constituída de poemas criados pelo autor a partir da observação de reproduções de trabalhos plásticos. Objetiva-se realizar um diálogo entre poemas desta obra com outros do autor, com a sua fortuna crítica e com trabalhos que refletem sobre Poesia e Artes Plásticas. São analisados seis pares de poesias/obras plásticas que fazem parte de Arte em Exposição, buscando situar os poemas em relação a outros da obra de Carlos Drummond de Andrade e comparando as imagens plásticas com os versos que elas motivaram. Cada análise é precedida do poema e da reprodução da obra plástica que o inspirou e encerra-se com algumas informações sobre estas obras e seus autores. Busca-se, através destes instrumentos, delinear uma visão que contemple, as duas expressões – a plástica e a poética, considerando as diferenças entre ambas, mas reconhecendo, nas duas manifestações, importantes contatos. A conjugação das duas expressões artísticas em Arte em Exposição propõe ao observador uma leitura diversa. A mobilidade do olhar (que passeia de uma forma de expressão para a outra) pode torná-lo mais abrangente e as duas imagens, uma vez confrontadas, parecem acrescidas de novos conteúdos. Acredita-se que o exercício de compará-las permite à nossa percepção leituras mais variadas.

As lacases, p-diphenol-O2-oxidoredutases, são enzimas que desempenham papel fundamental na oxidação de monolignóis durante a biossíntese de lignina, estando, portanto, associadas a processos de crescimento e tolerância a alguns tipos de estresses abióticos. As lacases podem ser encontradas em bactérias, fungos, plantas e insetos. Estudos apontam que as lacases vegetais apresentam comportamento similar às de origem fúngica, atuando de formar complementar à rota de lignificação, em resposta ao estresse oxidativo, promovendo a detoxificação celular. As lacases são geralmente codificadas por famílias multigênicas. Através de análises in silico no genoma de eucalipto, o presente estudo identificou 54 genes codificadores de lacases (denominados EgLAC) que, filogeneticamente, se distribuem em seis diferentes subgrupos. Com base em dados de RNA-Seq, padrões distintos de expressão das lacases identificadas foram observados, sendo algumas enriquecidas em um dado órgão/tecido e outras com expressão não detectável pelo método. Análises de RT–qPCR de alguns genes selecionados com base em um banco de sequências expressas confirmaram, por exemplo, a expressão raiz-específica do gene EgLAC52 bem como as expressões preferenciais em raiz e folha dos genes EgLAC4 e EgLAC32, respetivamente. Em paralelo, a expressão de alguns destes genes em reposta a estresses foi investigado, e alterações na expressão relativa em resposta aos estresses oxidativo e osmótico foram constatadas, sugerindo a participação destas lacases em respostas a estresses abióticos.
Laccases are p-diphenol-O2-oxidoreductases encoded by multigene families widely distributed throughout the plant kingdom. They exhibit important roles in the oxidation of monolignols during lignin biosynthesis and are reported to be functionally involved in plant development, tolerance and response to stress. Apart from plants, laccases can be also found in bacteria, fungi and insects. Here, a genome-wide survey of the eucalyptus genome revealed the presence of 88 putative laccases genes. However, after meticulous analyzes using different approaches, the redundant sequences were discarded and 54 laccases genes (referred as EgLAC) were retrieved. These genes were phylogenetically distributed in six different subgroups. Based on RNA-Seq data, distinct organ/tissue expression patterns of the identified EgLAC genes were ascertained. The vast majority showed organ/tissue-enriched expression, while certain genes exhibited no detectable expression. RT-qPCR analyzes confirmed the organ/tissue expression patterns of a representative set of genes such as, for example, the rootspecific expression of EgLAC52 and the root and leaf preferential expressions of genes EgLAC4 and EgLAC32. Further expression profiling of selected EgLAC genes in response to oxidative and osmotic stresses revealed differences in their relative expression, with some genes being stress-induced. These results suggest that certain laccases might be implicated in abiotic stress responses.

Texto completoFUNDAÇÃO PADRE LEONEL FRANCA
A face humana é interessante e desafiadora acima de tudo pela sua familiaridade. Essencialmente, é a parte do corpo utilizada para reconhecer indivíduos. Assim como a face, a fala é um importante instrumento na forma de comunicação do ser humano. Através da fala é possível externar pensamentos e, muitas vezes, ela indica o estado de ânimo em que uma pessoa se encontra. Juntos, fala e face são os principais elementos de interatividade entre os seres humanos. Contudo, reproduzir com naturalidade e fidelidade as peculiaridades destes dois elementos no universo computacional não é uma tarefa simples, constituindo-se em tópicos de pesquisa em diversas áreas, em particular na animação facial. Entre os diversos tipos de sistemas de animação facial, destacam-se como diretamente relacionados a este trabalho aqueles que envolvem a sincronização da fala de um personagem com a animação da sua face. Sistemas desse tipo são conhecidos como talking head ou talking face. Para o desenvolvimento de um sistema talking head, é necessário identificar as possíveis abordagens para a modelagem dos dois elementos básicos: fala e face. Os modelos utilizados irão influenciar não apenas a maneira como a animação é conduzida, mas a própria forma de interatividade do sistema. Uma contribuição importante deste trabalho é o estudo das possíveis abordagens e a proposta de uma taxonomia para a classificação de sistemas talking head. A partir da taxonomia proposta e fazendo uso de uma determinada abordagem para cada parâmetro analisado, foi desenvolvida uma aplicação que recebe como entrada um texto contendo a fala e anotações de expressividade e gera como saída, em tempo real, a animação de um personagem virtual enunciando o texto de entrada com o áudio e os movimentos faciais sincronizados. O sistema desenvolvido, denominado Expressive Talking Heads, explora a naturalidade da animação facial e ao mesmo tempo busca oferecer ao usuário uma interface com interatividade em tempo real. O Expressive Talking Heads pode ser executado tanto no modo isolado (stand alone) como acoplado a navegadores para a web, tendo sido projetado e desenvolvido com a preocupação de oferecer uma solução independente da plataforma e do sistema operacional utilizados.
The human face is interesting and challenging mainly because of its familiarity. Essentially, it is the part of the human body that is used to recognize individuals. As well as the face, the speech is an important instrument for human communication, allowing the exteriorization of thoughts and the definition of emotions. Together, speech and face are the main elements of interactivity among human beings. However, the natural and faithful reproductions of the pecularities of these elements in the computational universe is not a simple task, constituting topics of the research in the diverse areas, particularly in facial animation. Among the diverse types of facial animation systems developed, those that involve the facial animation of the virtual character combined with speech synchronization are distinguished as directly related to this work. These kinds of systems are known as talking head or talking face. Fot the development of a talking head system, it is necessary to identify the possible approaches for the speech and face modeling. The models used will influence not only the way that the animation is performed, but it will also affect the system´s interactivity. An important contribution of the present master thesis is the study of several possible approaches for the main elements and the proposal of taxonomy for the classification of the talking head systems. From the proposed taxonomy and making use of one approach for each analyzed paramenter, an application was developed that receives as input a text composed by the character´s speech and genus, language and emotion parameters, and it generates as output, in real time, the animation of a virtual character uttering the input text with speech synchronization and expressiveness. The system developed, called Expressive Talking Heads, explores the naturalness of facial animation and it seeks to offer the user a real- time interactivity interface. The Expressive Talking Heads system can run as a stand-alone applicattion or connected to web browsers. It was designed and developed to provide a platform and operating system independent solution.

Texto completoOur study was characterized to describe the expression profile of nine actin genes present in the genome of Aedes aegypti throughout the mosquito\'s life cycle. QRT-PCR experiments confirmed the stage-specific expression of two genes as already previously characterized genes with induction peaks of male pupae (AeAct-3) and female pupae (AeAct-4). Two other genes already characterized, also had their expression profiles confirmed. The AeAct-1 showed in low expression and AeAct-2 showed induction peaks in larvae of fourth instar. The remaining actin genes showed expressed in all the analyzed intervals. The induction peaks for all genes were found in pupae or larvae of fourth instar. This characteristic is due to the fact that actin is a structural protein, justifying the high transcription in late larvae and mainly in pupae, stage where the complete metamorphosis of the insect occurs.

Texto completoThis dissertation analyzes the results of several transcription simulations using the binary model of externally regulated gene expression. The number of mRNA molecules and the state of the gene were considered as stochastic variables. In this model the gene may be in the active state (ON) or repressed state (OFF) and the change of gene state occurs at determined rates in each simulation for activation and for repression. The number of mRNA molecules is changed by the transcription of new molecules and by the degradation of existing molecules at determined rates. These simulations used the Gillespie algorithm for exact stochastic simulation of coupled chemical reactions was used

Putative recombinant viruses were selected and examined for the expression of these two gene products. Although permanent recombinant viral stocks were not established, it was demonstrated that pp60$ sp{ rm c-src}$ can be produced in insect cells following transient transfection. Furthermore, this protein was shown to be biologically active as measured in the in vitro immune complex kinase assay. pp60$ sp{ rm c-src}$ produced in insect cells is capable to phosphorylating an exogenous substrate, enolase, in addition to undergoing autophosphorylation.

Texto completoAnsiktsuttryck spelar en viktig roll i områden som mänsklig kommunikation eller vid utvärdering av medicinska tillstånd. För att tillämpa maskininlärning i dessa områden skulle det vara fördelaktigt att ha en representation av ansiktsuttryck som bevarar människors uppfattning av likhet. I det här arbetet används ett data-drivet angreppssätt till representationsinlärning av ansiktsuttryck. Metodologin bygger på s. k. Variational Autoencoders och eliminerar utseende-relaterade drag från den latenta rymden genom att använda neutrala ansiktsuttryck som extra input-data. För att förbättra kvaliteten på den inlärda representationen så modifierar vi a priori-distributionen för den latenta variabeln för att ålägga den struktur på den latenta rymden som är överensstämmande med mänsklig perception av ansiktsuttryck. Vi utför experiment på två dataset och även insamlad likhets-data och visar att den människolika topologin i den latenta representationen hjälper till att förbättra prestandan på en typisk emotionsklassificeringsuppgift samt fördelarna med att använda en probabilistisk generativ modell när man undersöker latenta dimensioners roll i den generativa processen.

Despite the significant effort devoted to methods for expression recognition, suitable training and test databases designed explicitly for expression research have been largely neglected. Additionally, possible techniques for expression recognition within an Man-Machine-Interface (MMI) domain are numerous, but it remains unclear what methods are most effective for expression recognition. In response, this thesis describes the means by which an appropriate expression database has been generated and then enumerates the results of five different recognition methods as applied to that database. An analysis of the results of these experiments is given, and conclusions for future research based upon these results is put forth.

Texto completoThe Micro-expressions (MEs) are very important nonverbal communication clues. However, due to their local and short nature, spotting them is challenging. In this thesis, we address this problem by using a dedicated local and temporal pattern (LTP) of facial movement. This pattern has a specific shape (S-pattern) when ME are displayed. Thus, by using a classical classification algorithm (SVM), MEs are distinguished from other facial movements. We also propose a global final fusion analysis on the whole face to improve the distinction between ME (local) and head (global) movements. However, the learning of S-patterns is limited by the small number of ME databases and the low volume of ME samples. Hammerstein models (HMs) are known to be a good approximation of muscle movements. By approximating each S-pattern with a HM, we can both filter outliers and generate new similar S-patterns. By this way, we perform a data augmentation for S-pattern training dataset and improve the ability to differentiate MEs from other facial movements. In the first ME spotting challenge of MEGC2019, we took part in the building of the new result evaluation method. In addition, we applied our method to spotting ME in long videos and provided the baseline result for the challenge. The spotting results, performed on CASME I and CASME II, SAMM and CAS(ME)2, show that our proposed LTP outperforms the most popular spotting method in terms of F1-score. Adding the fusion process and data augmentation improve even more the spotting performance
