Abstract:
La définition d'un modèle géologique 3D est un travail complexe, fait à partir de données peu précises et laisse une large place à l'interprétation du géologue. Pour valider la cohérence de son modèle, le géologue dispose de méthodes de restaurations qui consistent à déplier le modèle pour voir si avant déformation, le modèle apparaît probable. Néanmoins l'efficacité de ces méthodes en 3D est sujette à caution. Aussi, une autre approche présentée dans cette thèse et implémentée dans le géomodeleur GOCAD, consiste à construire de nouveaux horizons en se basant directement sur les données les pl

Les logiciels de modélisation en géologie structurale (géomodeleurs) s'appuient principalement sur l'utilisation de trois types de structure de données pour représenter les interfaces géologiques : des grilles, des surfaces paramétriques et des surfaces triangulées. Si les deux premiers types ont été largement utilisés dans le passé, le dernier prédomine aujourd'hui en modélisation structurale et se révèle être le mieux adapté pour une modélisation aisée de réservoirs pétroliers complexes.

L’équilibrage de structures géologiques 3D est une méthode de validation d'un modèle structural par analyse de sa déformation au cours du temps.

Abstract:
Sexual development begins with the process by which the bipotential gonads of the embryonic urogenital ridge develop into either testes or ovaries. In the mouse, sex determination occurs at around 11.5 dpc and depends on the presence or absence of the Y chromosome and the associated activity of the testis-determining gene, Sry, in supporting cell precursors. The mutually antagonistic male and female developmental pathways are regulated by many cellular and molecular processes, disruption of which can lead to disorders of sex development (DSDs).

Recently, it has been shown that the development of HSC in the AGM region results from the maturation of haematopoietic precursors called pre-HSCs.

Abstract:
The inclusion of soya as a dietary protein source in the formulated feed, Abfeed® S34 (Marifeed Pty (Ltd), Hermanus) for farmed abalone, Haliotis midae has resulted in larger gonads during reproductive seasons compared to the gonads of abalone fed kelp or diets that included fishmeal as the only main protein source. The aim of this study was to determine if the isoflavones present in the soya were responsible for this increase in gonad size and the subsequent effects on farmed abalone growth. Animals weighing between 40-50 g were fed one of seven isonitrogenous and isoenergetic diets containin

Abstract:
A partir da hipófise de Astyanax altiparanae foram clonados e caracterizados os cDNAs completos para fshb, lhb e gpha. Das gônadas, foram clonados os cDNAs para fshr e lhr. As análises filogenéticas destes genes demonstram uma proximidade com as sequências homólogas das ordens Siluriformes e Cypriniformes. Por meio de qPCR, detectamos que a expressão dos mRNAs para as gonadotropinas foi restrita à hipófise, ao passo que dos receptores foi restrita às gônadas. Foi detectado que os mRNAs/proteínas para subunidades beta são expressas por diferentes populações de células gonadotrópicas. Nas gônada

Abstract:
Haematopoietic stem cells (HSC) are invaluable, due to their potential to treat malignant and non-malignant diseases. Modern medicine requires a reliable source of human HSCs (hHSCs) for efficient transplantations, which in many cases cannot be obtained from a single donor. Therefore, the ability to amplify donor hHSCs ex vivo would be an ideal alternative. Past attempts to expand hHSCs in vitro, demonstrated that the protocols developed so far have limited success. My research studied the factors which can affect the optimal culture of transplantable HSCs using a 3D culture system that had pr

Abstract:
Social status influences reproductive physiology in many species, and sex change in marine teleost fishes provides an excellent model to understand how an organism can modulate its reproductive system in response to social stimuli. The series of experiments presented in this dissertation has focused on the proximate mechanisms underlying sex change and, in particular, the neuroendocrine factors that might translate social information into physiological changes. The bluebanded goby (Lythrypnus dalli) is a sexually plastic fish, and the dominant female typically changes sex when the male is remo

Abstract:
Abstract The embryonic urogenital system generates the metanephric kidneys, the gonads and the adrenal glands, and its development is based on sequential and reciprocal cell and tissue interactions. The mechanisms which regulate urogenital ontogeny are still poorly understood. In this thesis, the roles of Wnt-4 and ErbB4 functions in gonad and kidney development were analysed by using in vivo functional genomic technologies. Wnt-4 is crucial in female development since its absence leads to a partial female to male sex reversal. We found that Wnt-4 mediated the interactions between the somatic
