Full textActivated carbons were prepared by phosphoric acid activation from Arabica coffee grounds at different impregnation ratios (defined as the ratios of weight (g) of H3PO4 to the weight (g) of precursor) : 30, 60, 120 and 180 % by heating to 450 °C in air. The adsorption properties of the Prepared Activated Carbons (PACs) have been compared to a commercial activated carbon (CAC) (obtained by steam activation) and related to their preparation methods, porous structure and surface chemistry. The PACs and CAC were characterized for their surface chemistry by thermogravimetric analysis, Infra-Red spectroscopy, pH measurement of the point of zero charge (pHpzc), surface functional groups semi-quantitative titrations ("Boehm" method) and X-ray microanalysis; and for their porous structure and morphology by nitrogen adsorption at 77 K. Scanning Electron Microscopy (SEM) and methylene blue adsorption. The PACs and CAC were compared for their adsorption of "Nylosan Red N-2RBL" (Clariant) which is an anionic (azo) dye used in Nylon (polyamide 6 and polyamide 6. 6) dyeing

Full textThe chemical composition of wild oilseeds, such as Lophira lanceolata (Ll) and Carapa procera (Cp) of Benin is mostly unknown. Yet they undergo crafted transformations for food, cosmetic and therapeutic purposes. This study aims to characterize their seeds, hulls and woods. From these crops, different oils have been extracted. One of them has been produced in rural area according to aqueous ancestral method. On the whole, oils of Ll have presented an interesting nutritional profile. They are rich in polyunsaturated fatty acids (> 50% m/m: mass for mass), especially that extracted by artisanal process. Beyond its good chemical properties, it provides essential fatty acids, phytosterols such as lupeol and more tocols compounds. Roasting and the use of enzymes have also assessed the impact of these methods on the chemical composition of LI seeds. Differently, Cp oil’s has an abundant presence of MUFA, tocotrienols (85.56% w/w) and the richest composition in lanosterol (28.03%, m/m). The seeds cakes, hulls and wood of both species showed various distributions on chemical components (extractives, hemicellulose, cellulose and lignin). The characterization of hemicelluloses from different parts of plants has shown that they are essentially glucuronoxylans type. Extractives also offered a wide range of compounds mostly appreciated for industrial and pharmaceutical purposes. The chemical composition of the shells of Lophira was rich in organic compounds such as lignin (32.13%, dry weight) so their biosorbent capacity was evaluated. They showed methylene blue good adsorption capacity in aqueous solution, which highlighted their potential use in the purification of wastewater

Full textTo respond to the emerging resistance of Plasmodium falciparum to artemisin derivatives, many strategies are currently under discussion. Among them, adding another antimalarial drug to the existing bi-therapies has been proposed. Among the possible third drugs, Methylene Blue (MB) is a good candidate as it present many advantages: early access to a pure active ingredient responding to pharmacopeia grade, a low manufacturing cost, and a proven efficacy against asexual stages of multiresistant malaria strains associated with a strong anti-gametocidal activity responsible for transmission. Many clinical trials demonstrated MB efficacy in malaria treatment, however no galenic research was done to improve its bioavailability and antimalarial activity, reduce side effects and improve patient adherence to treatment. Our research concentrated on two complementary directions: In order to improve MB bioavailability in solution, we encapsulated it with nucleolipids (diC16dT and DOTAU), and tested its antimalarial efficacy in vitro. This nanoformulation partially protected MB against reduction and light degradation, without alteration of its antimalarial efficacy against two P. falciparum strains (chloroquinosensitive and multiresistant). To propose access to an optimized oral form, gastro-resistant tablets were developed. Use of a humid granulation process allowed to obtain a granule highly dosed in MB, easier to handle, with better physico-chemical characteristics. We obtained homogeneous tablets with variable options in drug dosage. A gastro-resistant coating was added, with the aim to eliminate the vomiting side effect and improve compliance. Complementary evaluation of the proposed formulations (nanonucleolipids and gastro-resistant tablets) will be conducted to confirm their interest and evaluate their industrial feasibility under Good Manufacturing Practices. A clinical evaluation of the tablets is currently considered by an international MB – malaria consortium newly created

Full textPolyglutamine (PolyQ) diseases are a class of nine hereditary neurodegenerative diseases, including Spinocerebellar ataxia type 3 (SCA3) and Huntington's disease (HD), which are primarily caused by expansion of CAG repeats in coding region of their corresponding genes. Despite vigorous research on PolyQ, no efficient therapy is currently available for affected patients. In this thesis, we designed new Drosophila models of SCA3 and HD to identify new mechanisms involved in these diseases and used them in drug screening assays. As heart failure is a prominent cause of death in HD, we designed new heart models by overexpressing expanded (mHtt) or non expanded forms of Nter Huntingtin (Htt) fragments. Characterization of these models revealed significant cardiac hypertrophy that mimics the human HL phenotype. Using inducible systems we could identify critical stages for mHtt induced heart impairments. In addition we showed that treatment of flues with Methylene blue improves mHtt induced heart hypertrophy and cardiac function. We also characterized, in HD and SCA3 Drosophila inducible models within CNS, impairments of several physiological and behavioral parameters including average life span, circadian activity and rhythmicity, and sleep cycles. Characterization of these models allowed us to screen a number of genetic modifiers and a medium sized library of compounds. A proteomics study on a glial specific RD model was also performed. We discuss the new putative therapeutic targets identified by these three complementary approaches

Full textThe aim of our work was to study new aspects of the pathophysiology and treatment of anaphylactic shock in the Brown Norway rat. The first part of this thesis focuses on the systemic and regional pathophysiology of anaphylactic shock which is accompanied by a rapid decrease in cardiac output, a sudden alteration of autoregulation of cerebral blood flow and a respiratory dysfunction involving swelling of the airways and bronchospasm. The second part of our work focuses on the therapeutic management of anaphylactic shock. Epinephrine was found to be superior to vasopressin, to inhibit bronchospasm and decrease microvascular permeability, allowing a better preservation of the cerebral oxygenation, in particular in the region of the hippocampus. Furthermore, it provided also an alleviation of bronchospasm and of bronchial hyperperméabilté in the early phase of anaphylactic shock. We also compared the effects of three types of fluid therapy administered in combination with adrenaline during anaphylactic shock, demonstrating the superiority of the administration of a macromolecular solution such as HES compared to hypertonic saline fluids. Finally we were able to highlight the usefulness of the administration of methylene blue (3mg/kg) demonstrating the existence of a synergistic effect with adrenaline during anaphylactic shock
