Abstract:

Crystallization from supercritical fluids was studied as a nontoxic, noncontaminating alternative to conventional techniques for purification and size manipulation of pharmaceutical solids. To proceed with crystallization solubilities of several pharmaceutical compounds in supercritical carbon dioxide were experimentally determined and modeled using solid-vapor phase equilibria. The compounds studied included benzoic acid, salicylic acid, aspirin, griseofulvin, and digoxin among others. A high pressure crystallizer was constructed and operated in batch and continuous modes. Supersaturation was

Abstract:

Morphine-6-glucuronide is a minor metabolite. representing 5% of an administered dose of morphine. The metabolite has analgesic activity exceeding that of morphine and may contribute to analgesia following morphine administration. The aims of the study were to attempt to identify the reasons behind the improved activity of morphine-6-glucuronide over the parent compound and to examine a series of 6-substituted compounds, based on 6-substituted benzoate esters, as potential mimics of morphine-6-glucuronide. Morphine-6-glucuronide was seen to have similar affinity to morphine at l1-opioid recept

Abstract:

Interactions are all around us, and as humans we may use words and gestures to communicate our intentions. At the micro level of fungi, communications are replaced by chemical signals and structure. These interactions fall into three distinctive categories: synergistic, where organisms help each other, as is the case with ectomycorrhizal fungi and tree roots, deadlock, or combat, where organisms fight for or defend a resource. When it comes to fungi-tree interactions, the fungi group of basidiomycetes fall into the latter category. At the onset of fungal infection, a living tree defends itself

Abstract:

The aim of this thesis was to test whether cross-linking ATP analogues could be used to provide direct evidence of the amino acid residues which contribute to the ATP binding domain of P2X receptors. The UV irradiation of 2-azido ATP caused the compound to cross-link to the P2X1 receptor and caused a significant reduction in the response to ATP. The reduction of cross-linking following the pre-treatment of cells in excess ATP suggested competition between ATP and 2-azido ATP for occupancy of the P2X receptor binding site. This was proven with the radio-labelling of the P2X1 receptor with 2-azi

Abstract:

Plant cuticles are the interface for plant-environment interactions, and the first barrier protecting plants from environmental stresses such as water loss and pathogens. Structurally, the cuticle consists of a hydrophobic polymer lattice, cutin, and cuticular waxes deposited inside and outside cutin. The major components of the cuticular waxes are aliphatics derived from very-long-chain (VLC) fatty acids, such as alkanes and aldehydes. Besides compounds with primary functionalities, some compounds with two or more functional groups have also been identified in cuticular waxes. However, only l

Abstract:

Organophosphorus compounds are widely used in agriculture as pesticides and in industry as petroleum additives and modifiers of plastics. Some of these compounds are capable of inducing an irreversible neuropathy developing weeks to months after exposure, yet there is no effective treatment. This may be due in part to the lack of knowledge of how this neuropathy develops. In this dissertation, it is proposed that as a consequence of a triggering event, peripheral nerves may be predisposed to an increase in calcium (Ca⁺⁺) mobilization and the neuronal accumulation of this cation. This increase

Lignin polymers provide natural rigidity to plant cell walls by forming complex molecular networks with polysaccharides such as cellulose and hemicellulose. This evolved strategy equips plants with recalcitrance to biological and chemical degradation. While naturally beneficial, recalcitrance complicates the use of inedible plant materials as feedstocks for biofuel production. Genetically modifying lignin biosynthesis is an effective way to generate varieties of bioenergy crops with reduced recalcitrance, but certain lignin-modified plants display undesirable phenotypes and/or unexplained effe

Abstract:

Abstract In this work a manometric respirometric measuring system was applied to practical environmental cases related to wastewater management and biodegradation studies of oil-contaminated soils and materials used in landfill structures. Pollution of groundwater, surface water and soils is a worldwide problem. Therefore, tests simulating the biodegradation behaviour of organic compounds in water media and soils have become increasingly important. Respirometric methods provide direct measurement of the oxygen consumed by micro-organisms in biodegradation processes from an air or oxygen-enrich

Abstract:

Ce travail a permis d'évaluer les effets de la contrainte mécanique sur l'exsudation racinaire du maïs (Zea mays l. , variété Dea) et d'examiner l'importance de ces effets en relation avec le stade de développement de la plante. La culture des plantes a été conduite en conditions stérile et hydroponique. La contrainte mécanique a été simulée à deux niveaux d'intensité, à l'aide de billes de verre de 1 et 4 mm de diamètre. Ces traitements ont été comparés à un témoin sans billes. Les résultats ont montré que la croissance de la plante est influencée par la contrainte mécanique. Cette dernière a

Abstract:

Chez de nombreuses Angiospermes, la pollinisation croisée est nécessaire pour le succès de la reproduction. La plupart de ces plantes ont évolué afin de favoriser la pollinisation entomophile, principalement assurée par les abeilles. C'est le cas des Cucurbitacées, dont le melon (Cucumis melo L.), importante culture du sud de la France et le concombre d'âne (Ecballium elaterium (L.) A. Rich.) plante spontanée endémique du bassin méditerranéen, les deux modèles de cette étude. Afin de mieux comprendre les relations plante-pollinisateur,nous avons choisi de caractériser le couple pollen de Cucur
