Texte intégralThis project is focused on the study of synthetic materials used by Portuguese artists in the twentieth century. The aim of the study was the molecular characterization of vinyl and acrylic polymers used since the 1960s and the study of their photodegradation and evolution over time. In modern and contemporary art, water based synthetic emulsions have been widely used as painting binding media, especially acrylic and vinyl based emulsions. In some countries like Portugal where the first aqueous emulsions used as paint binders were the poly(vinyl acetate) – PVAc – ones, both as household and artist’s paints, the study of vinyl polymers is of particular importance. In Portugal these emulsions were used by outstanding artists like Joaquim Rodrigo and Ângelo de Sousa since the 1960s. In order to guarantee the preservation of the artworks for the future generations it is essential to understand how these paints will behave upon ageing. The molecular photodegradation of PVAc was studied and the presence of degradation products on reference and model samples, as well as on dated artworks was investigated. Paintings by Joaquim Rodrigo and Ângelo de Sousa, and also a hand painted catalogue for the Sabu vinyl artists’ paints, were selected as case studies. The characterization of micro-samples from the artworks provided useful information on the real evolution of the polymer binder over time. Accelerated photodegradtion studies were performed by the exposure of PVAc films on an ageing chamber equipped with a xenon-arc lamp. The behaviour of PVAc (homopolymer) was compared with a commercial emulsion(Vulcano V7) and paint reconstructions prepared in the laboratory. The results achieved by means of infrared microspectroscopy (FTIR) point out the considerably stable nature of these binding media as no molecular evidence was obtained concerning the formation of other carbonyl functions, the disappearance of the PVAc carbonyl or the formation of hydroperoxides. The polymer photodegradation process was further studied by means of size exclusion chromatography (SEC), following the molecular weight distribution and correspondent average molecular weights. It was concluded that no side-chain reactions are taking place and that main-chain scission is the foremost degradation mechanism, although not affecting the polymer performance significantly. The influence of pigments, such as titanium dioxide and iron oxide, on the polymer’s stability was also considered and it was concluded that they do not promote degradation, which might be explained due to pigment encapsulation in inert materials inhibiting its photocatalytic behaviour. The photodegradation quantum yield was determined as 7.4 x 10-8 at 313 nm for PVAc homopolymer; therefore, degradation is quantified and comparisons may be performed for different polymers. A parallel study, according to a similar experimental approach, was undertaken on the stability of poly(methyl methacrylate) – PMMA – used as acrylic sheet by the Portuguese artist Lourdes Castro.

Texte intégralEls polímers són omnipresents a la nostra vida diària, presents en múltiples aplicacions industrials i involucrats en processos biològics essencials. Per exemple, l’ADN, les proteïnes i els sucres poden ser considerats polímers, normalment denominats biopolímers. Aquells polímers amb un gran nombre de grups carregats són coneguts com a polielectròlits i freqüentment classificats en termes de la seva ionització com a forts (completament ionizats) o febles (parcialment ionizats). En aquesta tesi, investigo diferents aspectes teòrics de les propietats conformacionals, elàstiques, difusives i d'ionització de polielectròlits febles i biopolímers. Per un costat, em centro en la complexa interació entre els graus de llibertat d'ionització i conformacionals dels polielectròlits febles utilitzant el model Site Binding Rotational Isomeric State (SBRIS), desenvolupat recentment. S’introdueix una nova tècnica analítica, el mètode Local Effective Interaction Parameters (LEIP), per resoldre el model SBRIS incloent les interaccions electroestàtiques intramoleculars de llarg abast. El model es valida comparant els resultats amb la solució obtinguda per simulacions Monte Carlo a pH constant. El model SBRIS s’utilitza per estudiar la resposta elàstica d’un polielectròlit model. Es troba un nou règim de força en el que (i) les corbes força-extensió són significativament dependents del valor del pH i la força iònica (ii) la càrrega del polielectròlit es modificada per la acció de la força d’estirament. S’observa que les propietats conformacionals i elàstiques del polielectròlit es veuen significativament i moderadament afectades per la presència de fluctuacions en la càrrega, respectivament. Per l’altre costat, avaluo les propietats difusives i d'ionització de biopolímers en solució amb una elevada concentració de macromolecules. Aquestes condicions, conegudes com crowding macromolecular, son característiques dels medis biologics on fins el 40% del volum es ocupat per macromolecules. S’analitza la difusió de dues proteïnes globulars, α-chimiotripsina i estreptavidina, en diferents condicions de crowding macromolecular amb simulacions de Dinàmica Browniana. Es proposa un nou model de gra gruixut, anomenat Chain Entanglement Softened Potential (CESP), el qual es trobat que reprodueix quantitativament les dades experimentals. S’ha investigat l’efecte del \emph{crowding} macromolecular en les propietats conformacionals i de protonació de dues proteïnes intrínsecament desordenades (IDPs), histidina

Texte intégralAlonso, Fernández Irene. « The role of the medial temporal lobe in binding lyrics and melodies : a neuropsychological and neuroimaging approach ». Thesis, Lille 3, 2015. http://www.theses.fr/2015LIL30009/document.
Texte intégralSongs naturally couple music with language, constituting one of the most broadly used forms of music expression. Interestingly, songs require the simultaneous and integrated process of verbal (lyrics) and musical (melody) information to form a single memory trace. The medial temporal lobe has been identified as the key region for the integration of features of an event in episodic memory, also called the binding function. Nevertheless, the mechanisms by which the brain binds lyrics and melodies in song memory remain poorly understood. The purpose of this thesis is to elucidate the role of the MTL on the binding of lyrics and melodies for the creation of a unified song memory trace. First, the effects of unilateral hippocampus sclerosis on song processing were investigated in an fMR-adaptation study (Study 1). Patients with left hippocampal sclerosis showed adaptation deficits in response to lyrics as well as to the integrated representation of songs. To further explore the relation of these results with the emergence of memory for songs, the functional architecture of song memory was examined in a subsequent memory fMRI study (Study 2). The results support the implication of the hippocampus in song binding. Furthermore, the role of other structures, including the Inferior Frontal Gyrus (IFG), the Basal Ganglia (BG) and cerebellum was highlighted and discussed. Finally, Study 2 was adapted to test binding in patients following a unilateral temporal lobe excision for the relief of intractable temporal lobe epilepsy behaviorally in Study 3. Memory for lyrics as well for their melodic context was tested in an explicit recognition task. A strong deficit in lyrics recognition was found in patients with a left temporal lesion, and to a smaller degree in patients with a right temporal lesion. This deficit was correlated with deficits in verbal memory. Evidence from Study 3 further suggests that MTL structures may be crucial for encoding the detailed binding of lyrics with their melodic context, whereas implicit effects of an integrated representation of the song may be spared after MTL lesions. Altogether the studies presented in this thesis provide novel evidence for the role of the medial temporal lobe structures in binding lyrics and melodies for song memory. The present thesis proposes a comprehensive network of cortical and subcortical regions cooperating to successfully encode new songs. Finally, theoretical and clinical implications of these findings are considered

Texte intégralNo broadly protective vaccine is yet available for the prevention of group B meningococcal disease. One promising vaccine lead is the factor H binding protein (fHbp), a surface-exposed lipoprotein, which is present in all strains of Neisseria meningitidis. This protein binds human factor H (fH), contributing to the ability of these bacteria to avoid complement-mediated killing. The fHbp is a component of a serogroup B meningococcal vaccine currently in late-phase clinical development. Based on the sequence variability of the entire protein, fHbp has been divided into 3 variant groups or 2 sub-families and its architecture is modular, consisting of 5 variable segments, amino acid residues in position between 100 and 255 have been identified as important targets of variant-specific bactericidal antibodies. A panel of anti-fHbp mAbs has been produced from mice immunized with each of the 3 variants of fHbp and all their epitopes have been mapped, except that of the mAb designated JAR 36. This antibody was isolated from a mouse immunized with fHbp of the antigenic variant 3 group, but it cross-reacts with all fHbp sequences in the variant 2 group and elicits complement-mediated cooperative bactericidal activity with JAR 13 and JAR 11. We have screened phage displayed random peptide libraries to identify amino acid residues composing the JAR 36 epitope, putative mapping hypotheses have been then validated by constructing recombinant fHbps single-point variants through site-specific mutagenesis, and analyzing their reactivity with the mAb. Moreover, by using a computational tool, a total of seventeen residues have been identified as possibly constituting the epitope of JAR 36. Eight of these residues are located in a segment of fHbp previously recognized to play an important role in the binding of JAR 36 and four of them are common in variant groups 2 and 3. Both the amino acid identified by phage display and the “in silico”-predicted epitope are located in the proximity of the fH-binding site. This finding is according with previous experimental data, of JAR 36 partially inhibiting binding of fH to fHbp. The data reported will help in characterizing the molecular mechanism of immune protection against MenB, toward the development of safer and effective protein-based vaccines for the prevention of group B meningitis.

Escherichia coli enteropatogÃnica (EPEC) à um importante patÃgeno associado Ãs doenÃas diarreicas. InfecÃÃes intestinais ocasionam comprometimento da barreira intestinal e um dos primeiros mecanismos de resposta à recuperaÃÃo à a migraÃÃo das cÃlulas intestinais. As principais proteÃnas que regulam esse processo sÃo as pequenas GTPases Rho, Rac1, RhoA e Cdc42A. A alanil-glutamina (Ala-Gln) estimula este processo migratÃrio, entretanto os mecanismos envolvidos nesta resposta ainda sÃo desconhecidos. Desse modo, investigou-se o efeito de uma cepa selvagem e padrÃo (E2348/69) de EPEC, e de uma cepa comensal E. coli HS na migraÃÃo celular intestinal, bem como a regulaÃÃo da transcriÃÃo e expressÃo gÃnica das GTPases Rho e o papel da suplementaÃÃo com Ala-Gln no processo de migraÃÃo na presenÃa ou ausÃncia da infecÃÃo. A infecÃÃo pelas cepas de EPEC e pela cepa comensal reduziram significativamente a migraÃÃo celular intestinal. Entretanto, houve uma maior reduÃÃo desse efeito nas cÃlulas infectadas pelas cepas de EPEC quando comparado Ãquelas infectadas pela cepa comensal de E. coli HS. Observou-se um alto percentual de cÃlulas necrÃticas, cerca de 30%, induzido pela cepa padrÃo de EPEC apenas nos tempo de 12 e 24 horas apÃs infecÃÃo. A adiÃÃo da Ala-Gln em cÃlulas nÃo infectadas estimulou significativamente e de modo dose dependente a migraÃÃo apÃs 24 horas. PorÃm, quando esse nutriente foi adicionado durante 12 e 24 horas na presenÃa da infecÃÃo, nÃo houve uma reversÃo do dano. Em relaÃÃo à expressÃo gÃnica das GTPases Rho, observou-se um aumento da transcriÃÃo de rac1 nas cÃlulas que haviam sido infectadas pelas cepas de EPEC e E. coli HS, bem como um aumento da transcriÃÃo de rhoA nas cÃlulas infectadas pela cepa padrÃo de EPEC apÃs 2 horas da infecÃÃo. Todavia, na anÃlise das proteÃnas por imunofluorescÃncia, RhoA e Cdc42 mostraram-se aumentadas nas cÃlulas infectadas pela EPEC padrÃo quando comparado ao controle. Enquanto que as cÃlulas infectadas com a cepa selvagem de EPEC observou-se um aumento de Rac1 e reduÃÃo de RhoA. Esses dados mostraram que a migraÃÃo das cÃlulas intestinais à reduzida principalmente pelas cepas patogÃnicas de EPEC, ao regular a transcriÃÃo e expressÃo gÃnicas das proteÃnas GTPases Rho. A suplementaÃÃo com Ala-Gln em cÃlulas intestinais promoveu a migraÃÃo celular apenas na ausÃncia da infecÃÃo.
Enteropathogenic Escherichia coli (EPEC) is an important pathogen associated with diarrheal diseases. Intestinal infections cause impairment of the intestinal barrier and one of the earliest response mechanisms to recover is migration of the intestinal cells to cover the injured area. The key proteins that regulate cell migration are small Rho GTPases, Rac1, Cdc42 and RhoA. The alanyl-glutamine (Ala-Gln) increases this migration process, however the mechanisms involved in this response are still unknown. Thus, we investigated the effect of a wild type strain and standard (E2348/69) of EPEC strain and a commensal E. coli HS on intestinal cell migration, as well as transcriptional regulation and gene expression of Rho GTPases and the role of supplemental Ala-Gln in the migration process in the presence or absence of infection. Infection by EPEC strains and commensal E. coli HS significantly reduced intestinal cell migration. However, this effect was more pronounced in cells infected by the strains of EPEC compared to those infected by the commensal strain of E. coli HS. We observed a high percentage of necrotic cells, about 30%, induced only by EPEC strain pattern 12 and 24 hours after infection. The addition of Ala-Gln in uninfected cells significantly stimulated in a dose dependent migration after 24 hours. However, when this nutrient was added over 12 and 24 hours in the presence of infection, there was no reversion of the damage. Regarding the gene expression of Rho GTPases, we observed an increase in transcription of rac1 in cells that had been infected by the strains of EPEC and E. coli HS as well as an increase in rhoA transcription in cells infected with EPEC strain pattern at 2 hours after infection. However, the analysis of proteins by immunofluorescence, RhoA and Cdc42 shown to be elevated in cells infected with EPEC pattern when compared to the control. Whereas cells infected with wild EPEC strain was observed an increase of Rac1 and reduction of RhoA. These data showed that cell migration is reduced mainly by the intestinal pathogenic strains of EPEC, in regulating gene transcription and expression of the protein Rho GTPases. Supplementation with Ala-Gln in intestinal cells only promoted cell migration in the absence of infection.

Texte intégralParasites fatty acid binding proteins (FABPs) have an important role in infection process by these organisms. For this reason, these proteins are candidates as vaccine antigens against Schistosoma mansoni and Fasciola hepatica infection. In the present study, FABPs from F. hepatica were characterized and compared with Sm14 protein from S. mansoni, the best characterized parasite FABP, by sequence analysis and modeled structure. Type 1 and type 3 FABPs from F. hepatica were also cloned, expressed and purified. The results of this study indicated that type 3 FABP from F. hepatica is structural, immunological and functionally related with Sm14, a vaccine candidate widely studied. Due to the importance of Sm14 as a target for vaccine development for schistosomiasis, the characteristics presented by the FhFABP3 from F. hepatica suggest this protein as a candidate also important for the development of a vaccine against fasciolosis

Texte intégralINTRODUCTION: The history of spontaneous preterm birth in a previous pregnancy is considered the main and most important clinical risk factor for preterm birth, the leading cause of neonatal morbidity and mortality. About 25% of these patients will deliver prematurely again. Secondary prevention consists in the search for markers of increased risk, in order to institute appropriate therapeutic actions and to avoid unnecessary treatments. The hypothesis of this study is that there is a correlation between the results of the evaluation of the cervix and the test for phosphorylated insulin-like growth factor binding protein-1 (phIGFBP-1) and that the use of both in combination can predict the occurrence of preterm delivery with higher sensitivity. OBJECTIVES: To investigate the usefulness of the measurement of the cervical length and phIGFBP-1 rapid test in the prediction of preterm birth before 37 and 34 weeks, the existence of a relationship between the tests themselves, the best cutoff value of cervical length measurement at different gestational ages and the best time to carry out each of the exams. METHODS: Data of 101 women with previous preterm birth assisted at the Obstetrical Clinic of the Hospital das Clínicas, Faculty of Medicine, University of São Paulo between 2003 and 2008 were collected and subjected to secondary analysis. The measurement of cervical length and the phIGFBP-1 test were performed every three weeks, between 24 and 34 weeks gestation, and compared with the outcome of premature birth before 37 and 34 weeks, and the best cutoff value of the cervix was determined by receiver operator characteristic curves. RESULTS: Of the 101 pregnancies studied, 25 (24.8%) ended in preterm birth, of which 12 (11.9%) occurred at 34 weeks or less. The mean gestational age in each evaluation was 24, 27, 30 and 33 weeks, and the cutoff of the cervix were 22, 21, 20 and 16 millimeters, respectively. The measurement of cervical length showed the highest sensitivity (approximately 70%) and was able to predict preterm birth in all evaluations. The phIGFBP-1 test was not useful at 24 weeks, but was able to independently detect the risk of prematurity at 27, 30 and 33 weeks. Statistical association between the exams was observed, so that the mean cervical length was lower in pregnant women testing positive for phIGFBP-1. The combination of both tests significantly increased the sensitivity and negative predictive value. CONCLUSIONS: The measurement of cervical length by transvaginal ultrasound is a good marker of risk for preterm delivery at 24 weeks, and the test for phIGFBP-1 is useful after 27 weeks. The association of the two tests is valuable and shows high sensitivity and high negative predictive value in women at high risk for spontaneous preterm birth, when the first is preformed with 24 weeks, and the second with 27 weeks

Cellulose is an insoluble dietary fiber and is the most abundant polysaccharides in nature. It has been proved that cellulose can improve human health, such as promoting gastrointestinal peristalsis, reducing weight, preventing constipation and colon cancer. It has been reported that macrominerals binding capacity of fiber is related with particle size and water holding capacity. Volume mean diameter of cellulose was significantly reduced by media-milling, resulted in both the reducing particle size and molecular weight. For example, the molecular weight was reduced from 646.29 kDa to 117.1 kDa after 90 min media-milling. Via sediment method, the suspended cellulose yield a zeta potential of -16.6 mV, a negative charge. After media-milling, the absolute value of zeta potential was increased, indicates that nano/submicron cellulose dispersion is more stable, Isoelectric point(IEP) of cellulose raw material is pH 3.03, and dropped to 2.74 after 90 min media-milled, shows that after media-milling, cellulose particles are more negative-charged. Media-milling also improves WHC of cellulosic particles. By centrifugation method, WHC increased 7.9 fold after 30 min media-milling, but decreased after 30 min. Viscosity of cellulose dispersion increased first from 1.71 cp to 25.46 cp and then decrease after 30 min. WHC and viscosity were found correlated. Media-milling can also enhance Mg, Ca, Na, K binding capacity with a relationship with WHC.

Retouching material is the paint to fill the lacuna of color on art works during conservation process. The concept and technique of retouching from the western countries are more developed and comprehensive, the over viewing of the developing history and the material evolvment since hundreds centuries reveals the foundation of conservation wasn’t simply built in oe day. The binder of retouching material holds the key to determine the physical, chemical and photochemical properties, which also closely bonded with the handling ability and environmental condition. Owing to the fact of higher stability and easy to be modifying, the study of retouching binder leads toward the direction of synthetic resin. Based by the western conservation concept and technique, the conservation in Taiwan is striding forward to the international level. However, if the material that has been tested by museum condition can be directly transfer to the island climate of Taiwan is still a question of uncertain. Thus, this study choose three of the most recommended retouching material (1)watercolor coated with 5% acrylic resin Paraloid® B72, (2)acrylic resin Paraloid® B72 and (3)low molecule weight resin Laropal® A81 to proceed accelerate aging process with the simulation of Taiwan’s exterior condition, and measure the alter of color, gloss, adhesion and solubility to evaluate the stability and reversibility of the materials. The results shows that both the water color coated 5% Paraloid® B72 and Laropal® A81 have lower resistance against moisture, thus are not recommended for the use of exterior area. The stability and reversibility of Paraloid® B72 after aged is durable, and when the physical damages such as hollow and flaking occurred, the consolidation is achievable simply with pressure and heat. But the material is more suitable for hatching technigue rather than paint large area at once.
