Santos, Maria Margarida de Sousa dos. « Cerâmica Arqueológica, estudo comparativo da eficácia inicial de dois consolidantes – polímero acrílico e silicato de etilo ». Master's thesis, Faculdade de Ciências e Tecnologia, 2011. http://hdl.handle.net/10362/7524.
Texte intégralÉ frequente, em peças de cerâmica arqueológica, o aparecimento de fenómenos de desagregação. Para a conservação deste material há a necessidade de aplicação de produtos que aumentem a sua coesão e resistência mecânica. Dado existirem poucos trabalhos científicos sobre o desempenho de consolidantes alternativos, a utilizar em cerâmica arqueológica, sentiu-se a necessidade de desenvolver um trabalho laboratorial sobre essa temática. Assim, efectuou-se o estudo comparativo de avaliação da eficácia inicial de dois produtos comerciais, o Tegovakon V® e o Paraloid B-72®, como consolidantes. Foram utilizados provetes (sãos) em cerâmica vermelha cozida a 980 °C. Os consolidantes foram aplicados por imersão total e por pincelagem. A cerâmica foi caracterizada por DRX e os consolidantes por FTIR. A micro-estrutura da cerâmica foi caracterizada, antes e após a consolidação, por MEV-EDE, PM e μ-CT. A eficácia inicial do processo de consolidação foi avaliada através de uma série de ensaios laboratoriais, nomeadamente: porosidade acessível à água, absorção de água por capilaridade, velocidade de propagação de ondas longitudinais, resistência à compressão pontual, ângulo de contacto, tempo de absorção da micro-gota e caracterização colorimétrica. A consolidação é um procedimento que interfere nas propriedades físicas e comportamentais da cerâmica intervencionada. Essas alterações nas propriedades da cerâmica são função do consolidante e do método de aplicação. Nos provetes consolidados, por imersão, com Tegovakon V® verificou-se a redução de 62% da porosidade e 98% da capilaridade, o aumento de 4,8% da resistência mecânica e a alteração de ΔΕ de aproximadamente 7,7. Nos provetes consolidados, por imersão, com Paraloid B-72® verificou-se a redução de 4,5% da porosidade e 87% da capilaridade e o aumento de 4,5% da resistência mecânica. A alteração de ΔΕ, aproximadamente 12, foi superior nos provetes consolidados por pincelagem. Com base nestes resultados podemos afirmar que o consolidante que apresenta melhor desempenho, no que diz respeito à eficácia inicial, é o Tegovakon V® aplicado por imersão.

Texte intégralWe recently characterized two new mammalian specific genes, Tex19.1 and its paralog Tex19.2. Both genes are expressed in pachytene spermatocytes in adult testes. In addition, Tex19.1 is expressed in pluripotent cells (ES, EG, iPS and PGC cells), the inner cell mass of the blastocysts and the placenta. In order to decipher Tex19 functions, we generate three types of knockout (KO): i) KO of Tex19.1 ii) KO of Tex19.2 iii) double KO (DKO) of both genes. All Tex19.1-/- KO animals are growth-retarded and half of them die just after birth. This phenotype is probably linked to placenta defects. Surviving adults Tex19.1-/- KO males display a variable spermatogenesis phenotype, associated with an up-regulation of one endogenous retrovirus, MMERVK10C. Tex19.2 KO mice exhibit a subtle phenotype. Few seminiferous epitheliums are degenerated while the rest appear normal. DKO show a fully penetrant phenotype similar to the most severe Tex19.1-/- phenotype. DKO males exhibit small testes. Despite the presence of spermatogonia and spermatocytes, spermatogenesis is blocked at the pachytene stage. By RNA deep-sequencing on 10 days old DKO and WT testes, prior to histological phenotype, 114 genes are significantly up-regulated and 320 genes significantly down-regulated in the DKO compared to the WT. Gene ontology analyses show that among of these genes, two essential pathways are altered: meiosis and the piRNA pathway. Consistent with that, GST-pulldown and immunoprecipitation experiments demonstrate that MIWI, MILI, MAEL and MVH are partners of TEX19. Considering PIWI proteins function in the silencing of transposable elements through the piRNA pathway, we checked if TEX19 paralogs bind piRNA. By immunoprecipitation using WT and KO testes, we show that both TEX19.1 and TEX19.2 bind small RNA of 30 nucleotides through their VPTEL domain. This study highlights the pivot role of Tex19 paralogs in three essential functions of mammalian life cycle, i.e. pluripotency, placenta-supported in utero growth and fertility. The functional similarities of both paralogs, through the expression control of one endogenous retrovirus and the binding of piRNAs, lead us to propose that Tex19 paralogs are new members of the piRNA pathway

In order to interpret the results obtained from a microarray experiment, researchers often shift focus from analysis of individual differentially expressed genes to analyses of sets of genes. These gene-set analysis (GSA) methods use previously accumulated biological knowledge from databases such as the Gene Ontology (GO) or KEGG to group genes into sets based on their annotations. They aim to rank these gene sets in a way that reflects their relative importance in the experimental situation in question. The objective is that this approach reveals sets of genes with subtle but coordinated behaviour implicating specific biological processes or pathways in the response under study. Several GSA methods have been proposed and debates have ensued on the statistical foundations of the different approaches and the various hypothesis tests used. In particular, criticism has been directed at methods that rely on a strict cut-off to determine significant genes and those that assume genes are expressed independently. We show that paralogs, which typically have high sequence identity and similar molecular functions also exhibit high correlation in their expression patterns. This, together with the fact that the calculation of gene-set significance by all GSA methods is influenced by the number of genes in the gene set, means that sets with high numbers of paralogs are ranked in a biased manner that reflects more the redundant and dependent nature of para logs than any biological phenomenon.

Texte intégralEl nostre grup de recerca es centra en la traducció de proteïnes i més específicament en el mecanisme d’aminoacilació dels àcids ribonucleics (ARNs) de transferència (ARNt) per una família d’enzims essencials i universals anomenats aminoacil-ARNt sintetases (aaRSs). Al laboratori s’han analitzat el paper de les aaRSs en la traducció proteica, les seves funcions no canòniques, la seva evolució, així com la seva implicació en malalties humanes. Les aaRSs són components universals i essencials del codi genètic. La seva llarga historia evolutiva explica el creixent número de funcions que s’estan descobrint, tant per a elles com per a proteïnes paràlogues, més enllà del seu paper canònic en traducció genètica. Al laboratori, durant el procés d’obtenció d’un model a Drosophila melanogaster per a l’estudi de malalties humanes degudes a deficiències en l’aminoacilació d’ARNt, es va identificar un nou gen, paràlog de la seril-ARNt sintetasa (SeRS) mitocondrial, anomenat SLIMP. La proteïna SLIMP representa un nou tipus de proteïna similar a aaRS que ha adquirit una funció essencial a insectes, tot i la relativament baixa divergència respecta a una estructura d’SeRS canònica. Tot i amb això, són necessaris estudis addicionals per a identificar el paper biològic de SLIMP. Per aconseguir aquesta fita, s’ha portat a terme el projecte descrit en aquest manuscrit, el qual consisteix en anàlisis addicionals del fenotip resultant de la depleció de SLIMP in vivo, seguits d’estudis detallats de les interaccions moleculars amb àcids nucleics i proteïnes, per acabar amb un estudi dels efectes de SLIMP en la fisiologia cel•lular. En conjunt, els nostres resultats demostren que SLIMP s’uneix específicament a ARNs mitocondrials in vivo i in vitro. SLIMP interacciona amb SerRS2 i les dues són interdependents a nivell d’estabilitat proteica. La depleció de SLIMP o de SerRS2 redueix els nivells basals d’alguns ARNm mitocondrials, però la transcripció d’ARNt és manté inalterada. Es proposa un rol en la regulació post-transcripcional o en l’estabilitat dels ARNm madurs. Hem observat també que la depleció de SLIMP indueix l’aturada del cicle cel•lular en la transició G2/M. Aquests resultats suggereixen que SLIMP, o una conseqüència de la seva funció, podria tenir un paper d’enllaç entre els mitocondris i els factors de transcripció nuclears que regulen la proliferació cel•lular.

Proteinas de adesao celular sao essenciais para a invasao celular do hospedeiro mamifero pelo parasita Trypanosoma cruzi. Neste trabalho, nos mostramos que membros de gDispersed Gene Family-1 h, originalmente descrita como uma familia de sequencias nucleares repetitivas presente em varios cromossomos e compondo a terceira maior familia genica especifica deste parasita, contem caracteristicas de adesinas, incluindo quatro segmentos com similaridade significante a sequencia da subunidade ƒÀ7 de integrina humana. Ensaios de biotinilacao da superficie de parasitas e citometria de fluxo com anticorpos anti-DGF-1 indicaram que os membros dessa familia genica sao expressos na superficie das formas tripomastigotas. A genealogia de DGF-1, inferida por algoritmos de rede a partir de dados do Projeto Genoma da linhagem CL Brener de T. cruzi, sugere que essa familia genica pode ser dividida em pelo menos tres grupos com diferentes padroes de distribuicao de seus dominios funcionais. Analisando o perfil de uso dos codons, observou-se que as copias expressas apresentavam um uso preferencial de codons, favorecendo as bases GC, ao passo que copias nao-expressas, incluindo alguns pseudogenes, apresentavam uma distribuicao homogenea no uso de codons. A entropia informacional de Shannon foi utilizada como uma medida da variabilidade de sequencia e revelou que quatro segmentos de alta entropia coincidem com modulos funcionais putativos das proteinas preditas. Contradizendo a ideia de que alta variabilidade esta associada a selecao positiva, os resultados de dois testes distintos de selecao mostraram que posicoes altamente variaveis nao estao necessariamente sob selecao positiva. Nossa hipotese e de que membros de DGF-1 estao associados com a habilidade do T. cruzi se ligar a proteinas da matriz extracelular, como fibronectina e laminina, e especulamos sobre os mecanismos que gerariam diversidade nessas moleculas na ausencia de selecao.
Surface adhesion proteins are essential for Trypanosoma cruzi invasion of mammalian cells. Here we show that Dispersed Gene Family-1 (DGF-1) members, previously identified as nuclear repeated sequences present in several chromosomes and comprising the third largest T. cruzi-specific gene family, have conserved adhesin motifs including four segments with significant similarity to human beta 7 integrin. Flow cytometry and biotinylation assays with anti-DGF-1 antibodies indicated that, as expected, DGF-1 members are expressed on the trypomastigote surface. The DGF-1 genealogy, inferred using T. cruzi Genome Project data and network phylogeny algorithms, suggests that this gene family is separated in at least three groups with differential distribution of functional domains. To identify which members of this gene family are expressed we used a combined approach of RT-PCR and codon usage profiles, showing that expressed members have a very biased codon usage favoring GC whereas non-expressed members have a homogeneous distribution. Shannon information entropy was used to measure sequence variability and revealed four major high entropy segments in the extracellular domain of DGF-1 overlapping with important putative functional modules of the predicted proteins. Testing for natural selection, however, indicated that these high entropy segments were not under positive selection, which contradicts the notion that positive selection is the cause of high variability in specific domains of a protein relative to other less variable regions in the same molecule. We hypothesize that members of the DGF-1 family are associated with the ability of T. cruzi to bind extracellular matrix proteins, such as fibronectin and laminin, and speculate on mechanisms that would be generating the localized diversity in these molecules in the absence of selection.

Doctoral thesis, Uppsala University, Department of Earth Sciences, 2005. http://urn.kb.se/resolve?urn=urn:nbn:se:uu:diva-6179.
Texte intégralDevelopment of a predictive model for the distribution of diagenetic alterations and related evolution of reservoir quality of sandstones was achieved by integrating the knowledge of diagenesis to sequence stratigraphy. This approach allows a better elucidation of the distribution of eogenetic alterations within sequence stratigraphy, because changes in the relative sea level induce changes to: (i) pore water chemistry, (ii) residence time of sediments under certain near-surface geochemical conditions, (iii) variations in the detrital composition, and (iv) amounts and type of organic matter.
This thesis revealed that eogenetic alterations, which are linked to sequence stratigraphy and have an impact on reservoir quality evolution, include formation of: (i) pseudomatrix and mechanically infiltrated clays in fluvial sandstones of the lowstand and highstand systems tracts (LST and HST, respectively), (ii) kaolinite in tide-dominated deltaic and foreshore-shoreface sandstones of HST, Gilbert-type deltaic sandstones of LST and fluvial deltaic sandstones of LST, (iii) kaolinite and mechanically infiltrated clays in sandstones lying below sequence boundary, (iv) K-feldspar overgrowths in fluvial deltaic LST, (v) glaucony towards the top of fluvial deltaic LST immediately below and at transgressive surface (TS) and in foreshore and shoreface transgressive systems tracts (TST) below parasequence boundaries (PB) and maximum flooding surface (MFS), (vi) framboidal pyrite and extensive cementation by calcite and dolomite in foreshore and shoreface and tide-dominated deltaic TST, and shoreface and tidal flat HST bioclastic-rich arenites particularly in the vicinity of PB, TS and MFS, (vii) pervasive cementation by iron oxide in shoreface-offshore and shoreface sandstones of TST immediately below the MFS, (viii) zeolites and palygroskite in shoreface sandstones of TST and HST, particularly above PB, and (ix) cementation by siderite in Gilbert-type deltaic sandstones of LST, tide-dominated deltaic and foreshore-shoreface sandstones of HST and in tide-dominated deltaic sandstones of TST, particularly at MFS. Moreover, this thesis revealed that the distribution of eogenetic alterations strongly control, and thus provide information for constraining the distribution patterns of mesogenetic alterations, such as illitization of mechanically infiltrated clays and dickitization of kaolinite, and hence of related reservoir quality evolution of sandstones during progressive burial.

Doctoral thesis, Uppsala University, Department of Earth Sciences, 2006. http://urn.kb.se/resolve?urn=urn:nbn:se:uu:diva-6928.
Texte intégralThis thesis constrains the distribution of diagenetic alterations and their impact on reservoir-quality and heterogeneity evolution pathways in relation to depositional environments and sequence stratigraphy (systems tracts and key sequence stratigraphic surfaces) of four selected paralic and shallow marine siliciclastic successions.
Typical eogenetic alterations encountered include the dissolution and kaolinitization of framework silicates, which are closely associated to shoreface facies of forced regressive systems tract (FRWST), lowstand systems tract (LST), upper part of the highstand systems tract (HST), and below the sequence boundary (SB). These alterations are attributed to incursion of meteoric water owing to rapid and considerable fall in the relative sea level. Extensive carbonate cementation is most evident below marine and maximum flooding surfaces (MFS), whereas dissolution of carbonate cement and detrital dolomite occur in LST, HST and below SB. Parameters controlling the patterns and texture (microcrystalline vs. poikilotopic) of calcite cement have been constrained within sequence stratigraphic framework of the sandstones. Coarse crystalline to poikilotopic calcite textures of meteoric water origin are thus closely linked to the FRWST, LST and upper part of the HST sandstones and occur mainly as stratabound concretions, whereas microcrystalline calcite, which was precipitated from marine porewaters, occurs as continuously cemented layers in the transgressive systems tract (TST) and lower part of the HST sandstones.
Eogenetic alterations impose, in turn, profound control on the distribution pattern of mesogenetic alterations, and hence on reservoir quality evolution (destruction vs. preservation) pathways of sandstones. Eogenetic infiltrated clays, which occur in the tidal estuarine TST and HST sandstones, have helped preserving porosity in deeply buried sandstone reservoirs (≈ 5 km) through inhibition of extensive cementation by quartz overgrowths. Other essential findings of this thesis include deciphering the control on the formation of authigenic illite and chlorite by ultra-thin (≤ 1 µm thick), grain-coating clay mineral substrate.
