Texte intégralDoctor of Philosophy
Soil liquefaction continues to be one of the leading causes of ground failure during earthquakes, resulting in significant damage to infrastructure around the world (e.g., the 2010-2011 Canterbury earthquake sequence in New Zealand, 2010 Maule earthquake in Chile, and the 2011 Tohoku earthquake in Japan). Soil liquefaction refers to a condition wherein saturated sandy soil loses strength as a result of earthquake shaking. Surface manifestations of liquefaction include features that are visible at the ground surface such as sand boils, ejecta, cracks, and settlement. The severity of manifestation is often used as a proxy for damage potential of liquefaction. The overarching objective of this dissertation is to develop improved models for predicting triggering (i.e., occurrence) and surface manifestation of liquefaction such that the impacts of liquefaction on the natural and built environment can be minimized. Towards this end, this dissertation makes the following main contributions: (1) development of an approach for selecting an appropriate factor of safety (FS) against liquefaction for decision making based on project-specific consequences, or costs of mispredicting liquefaction; (2) development of an approach that allows better interpretations of predictions of manifestation severity made by the existing models in profiles having high fines-content, high plasticity soil strata (e.g., clayey and silty soils), given that the models perform poorly in such conditions; (3) development of a new model for predicting the severity of manifestation that more fully accounts for factors controlling manifestation; and (4) development of a framework for predicting liquefaction triggering and surface manifestation such that the distinct factors influential to each phenomenon are handled more rationally and consistently.

Texte intégralThe realm of molecular physical chemistry ranges from the structure of matter and the fundamental atomic and molecular interactions to the macroscopic properties and processes arising from the average microscopic behaviour.
Herein, the conventional electrodic problem is recast into the simpler molecular problem of finding the electrochemical, real chemical, and chemical potentials of the species involved in redox half-reactions. This molecular approach is followed to define the three types of absolute chemical potentials of species in solution and to estimate their standard values. This is achieved by applying the scaling laws of statistical mechanics to the collective behaviour of atoms and molecules, whose motion, interactions, and properties are described by first principles quantum chemistry. For atomic and molecular species, calculation of these quantities is within the computational implementations of wave function, density functional, and self-consistent reaction field theories. Since electrons and nuclei are the elementary particles in the realm of chemistry, an internally consistent set of absolute standard values within chemical accuracy is supplied for all three chemical potentials of electrons and protons in aqueous solution. As a result, problems in referencing chemical data are circumvented, and a uniform thermochemical treatment of electron, proton, and proton-coupled electron transfer reactions in solution is enabled.
The formalism is applied to the primary and secondary radiation damage to DNA bases, e.g., absorption of UV light to yield electronically excited states, formation of radical ions, and transformation of nucleobases into mutagenic lesions as OH radical adducts and 8-oxoguanine. Based on serine phosphate as a model compound, some insight into the direct DNA strand break mechanism is given.
Psoralens, also called furocoumarins, are a family of sensitizers exhibiting cytostatic and photodynamic actions, and hence, they are used in photochemotherapy. Molecular design of more efficient photosensitizers can contribute to enhance the photophysical and photochemical properties of psoralens and to reduce the phototoxic reactions. The mechanisms of photosensitization of furocoumarins connected to their dark toxicity are examined quantum chemically.

Texte intégralThe aim of this study is to determine and compare the posible antitumoral properties of several polyphenolic fractions, obtained from the extraction and fractionation of wine by-products consisting of grape skins, seeds and stems. These polyphenolic fractions have high antiradical potential and are mainly composed by flavanol monomers with or without gallate groups, glycosylated flavonols and mostly procyanidin oligomers. The effect of these fractions is analysed on cancer cells at cellular and metabolic levels. Moreover, as solar radiation in the UV range is the major source of adverse reactions in the skin and is one of the most efficient environmental carcinogen known, the possible capacity of these fractions to protect against cellular damage induced by ultraviolet radiation is evaluated and compared.
The results obtained in this study let us to confirm the polyphenolic fractions studied are very specific antiproliferative agents with very low cytotoxicity to non-proliferative normal cells, such as peripherial blood lymphocites (PBLs). Moreover, treatment with these fractions results in intracellular metabolic changes, restricting the ability of tumoral cells to proliferate and inhibiting glycolysis, being higher for the fraction rich in ECG containing oligomeric flavanols.
Like for the study of antitumoral effect at cellular and metabolic levels, the results obtained in the analysis of the protective capacity of these polyphenolic fractions against UV-induced damage, confirm them as potential natural chemopreventive agents.
Briefly, the results obtained in this study let us to conclude the polyphenolic fractions rich in procyanidin oligomers and gallate esters are the most efficient as antitumoral agents, active at both cellular and metabolic levels with low cytotoxicity. Additionally, polymerization and percentge of galloylation are also important in the efficacy of the polyphenolic fractions as protectors against damage induced by ultraviolet radiation, suggesting they may be useful for the prevention and treatment of a variety of solar UV light-induced human skin disorders.

Texte intégralThe DNA integrity and stability are essential to organisms’ health, fitness and, ultimately, to survival. This matter has been neglected in what concerns to fish in aquaculture systems, disregarding the potential impacts of both endogenous and exogenous factors. The manipulation of rearing conditions to achieve a fast-growing performance, as well as the occurrence (intentional or accidental) of agents/conditions, such as disinfectants, anesthetics, antibiotics and waterborne contaminants, may create stressful conditions passible to affect DNA integrity. Furthermore, in the long-term, this situation may compromise growth performance, animal welfare and a reduction in revenues. Seaweeds are a potential source of natural and high value compounds, with a large spectrum of biological activities and health benefits. It has been suggested that algae-enriched diet improves the growth, lipid metabolism, physiological activity, and disease resistance of various fish species; however, its anti-genotoxic potential was scarcely evaluated. Hence, this study aimed to evaluate the anti-genotoxic properties of a macroalgae-enriched diet to provide protection in gilthead seabream (Sparus aurata) against a genotoxic challenge (i.p. injection of 40 mg.kg-1 cyclophosphamide - CP), as well as to clarify if the potentially favorable effects of algae persist beyond the end of supplementation. The enriched diet was supplemented with 5% of equal parts of three species: Ulva spp. (Chlorophyta), Fucus spp. (Phaeophyta) and Gracilaria spp. (Rhodophyta). Thus, two groups of fish were differently fed during the first 30 days, until the CP injection, where they were separated depending on the diet/stimulus. Subsequently, in order to clarify the protective effect of the supplemented diet, 3 days after injection, half of each group previously fed with this diet has changed to the standard feed, keeping all the other groups the same way, for another 7 days. Genetic damage was evaluated through the erythrocytic nuclear abnormalities (ENA) and comet assays and the involvement of the antioxidant system as indication of a pro-oxidant status was assessed by superoxide dismutase (SOD), catalase (CAT), glutathione-S-transferase (GST), glutathione peroxidase (GPx) and glutathione reductase (GR) activities, as well as by total glutathione (GSHt) content. The elucidation of the oxidative DNA damage-protecting activity was made by adopting as diagnostic tool the comet assay improved with DNA lesion-specific enzymes, FPG and Endo III, which convert oxidized purines and pyrimidines into extra DNA single strand breaks, respectively. The results pointed that algae-enriched feed exhibits anti-genotoxic properties in gilthead seabream blood cells, evident in relation to DNA strand breaks and to chromosomal lesions, though it appeared more pronounced in the latter type of genotoxicity expression. This effect was depicted by fish sampled at the last sampling moment, since a significant recovery of chromosomal damage was evident in fish previously injected with CP. A clear oxidative DNA damage–protecting activity was displayed, particularly in the presence of a strong genotoxic insult occurring three days after CP injection, when purine oxidation was prevented by algae supplementation. Nonetheless, blood antioxidants were not altered by the supplemented diet, with the exception of GST activity that was induced as response to CP treatment. Considering the persistence of favorable effects, 7 days without algae uptake was enough to partially reduce the protection efficacy, mainly in what concerns to the oxidative DNA damage-protecting capacity. Overall, these results seem to be promising towards the benefits of seaweed inclusion in fish diet, offering a potential strategy to strengthen fish fitness, and thus, to invigorate aquaculture activity, also providing new insights on the mechanisms of DNA protection in fish.
A integridade e estabilidade do ADN são essenciais para a saúde e condição fisiológica geral dos organismos e, em última instância, para a sua sobrevivência. Este tema tem sido negligenciado no que diz respeito a peixes em sistemas de aquacultura, descurando os potenciais impactos de fatores endógenos e exógenos. A manipulação das condições de cultivo para alcançar um crescimento rápido, assim como a ocorrência (intencional ou acidental) de agentes/condições tais como desinfetantes, anestésicos, antibióticos e contaminação aquática podem criar estados de stresse passíveis de afetar a integridade do ADN. Além disso, a longo prazo, esta situação pode comprometer o desempenho do crescimento, o bem-estar animal e reduzir as receitas. As macroalgas marinhas são uma fonte potencial de compostos naturais de elevado valor, com um amplo espectro de atividades biológicas e benefícios para a saúde. Tem sido sugerido que uma dieta enriquecida com algas melhora o crescimento, metabolismo dos lípidos, atividade fisiológica e a resistência a doenças de várias espécies de peixes. No entanto, o seu potencial anti-genotóxico permanece por explorar. Assim, este estudo teve como objetivo central avaliar as propriedades anti-genotóxicas de uma ração enriquecida com macroalgas, em dourada (Sparus aurata), após um desafio genotóxico (injeção intraperitoneal de 40 mg.kg-1 de ciclofosfamida - CP). A ração enriquecida foi suplementada com um total de 5% de algas, incorporando três espécies em partes iguais: Ulva spp. (Chlorophyta), Fucus spp. (Phaeophyta) e Gracilaria spp. (Rhodophyta). Deste modo, dois grupos de peixes foram alimentados de forma diferenciada nos primeiros 30 dias, até ao momento da injeção, onde foram separados consoante a dieta/estímulo. Posteriormente, de modo a esclarecer o efeito protetor da ração enriquecida, 3 dias após a injeção, metade de cada grupo previamente alimentado com esta dieta viu a sua alimentação alterada para a ração padrão, mantendo-se todos os outros grupos iguais, durante mais 7 dias. Foi avaliado o dano genético através dos ensaios do cometa e de anomalias nucleares eritrocíticas (ANE), em paralelo com o estudo do envolvimento do sistema antioxidante, como indicação de um estado pró-oxidante, determinando as atividades da superóxido dismutase (SOD), catalase (CAT), glutationa-S-transferase (GST), glutationa peroxidase (GPx) e glutationa redutase (GR), bem como o teor total de glutationa (GSHt). A elucidação do dano oxidativo de ADN foi feita através do ensaio do cometa melhorado pela incubação com enzimas específicas de reparação de ADN, FPG e Endo III, que convertem purinas e pirimidinas oxidadas em ruturas extra de cadeia única, respetivamente. Os resultados demonstraram que a alimentação enriquecida com algas apresenta propriedades anti-genotóxicas em células sanguíneas de dourada, evidentes em relação às quebras de cadeias de ADN e a lesões cromossómicas, embora pareça mais pronunciada no último tipo de expressão genotóxica. Esse efeito foi particularmente notório no último momento de amostragem, uma vez que foi conseguida uma completa recuperação do dano cromossómico em peixes previamente injetados com CP. Foi ainda evidenciada uma clara atividade de proteção contra o dano oxidativo do ADN, particularmente na presença de um forte insulto genotóxico ocorrido três dias após a injeção de CP, o que foi expresso no impedimento da oxidação de bases purínica pela suplementação de algas. No entanto, os antioxidantes não foram alterados pela dieta suplementada, com exceção da atividade da GST que foi induzida como resposta ao tratamento de CP. Considerando a persistência de efeitos favoráveis, 7 dias após a remoção de algas da dieta foram suficientes para reduzir parcialmente a eficácia da proteção, principalmente no que diz respeito à capacidade de contrariar o dano oxidativo de ADN. Globalmente, estes resultados são promissores quanto à identificação dos benefícios da inclusão de algas na dieta de peixe, oferecendo uma estratégia potencial para fortalecer a condição dos peixes e, assim, revigorar a atividade aquícola, fornecendo também novos conhecimentos sobre os mecanismos de proteção do ADN em peixes.
