Full textThis manuscript addresses the physiology and ecophysiology of the microaerophilic hyperthermophilic bacterium Aquifex aeolicus, grown under different oxygen-supply conditions. Three experimental systems, jar, microcosm and fermentor were tested in those experiments: (1) a newly-engineered jar system containing 24-well microplates coupled to an automated controller. This system allows to study a broad spectrum of trophic factors or culture media formulations while maintaining a constant atmospheric composition; (2) microcosm systems were, here, proved ill-adapted to studying gas-phase trophic factors, and in some cases even to leading to false interpretations; 3) the fermentor system remains the best tool to studying the influence of dissolved O2 concentration (pO2) on A. aeolicus metabolism. Based on in-fermentor growth kinetic curves, we established that biomass density was maximum and constant at a pO2 in the range 0.006 to 6 mg/L and growth rate was maximum at a pO2 of about 2 mg/L. At a pO2 over 2 mg/L, oxygen level had a toxic effect on A. aeolicus growth. Under optimal oxygen supply (pO2 = 1.5 mg/L) and when H2 (100 mL/min) is the growth-limiting factor, energy catabolism is diverted towards thiosulfate consumption: at H2 flow-rates of 450 and 100 mL/min, 97% and 79% of O2 is reduced by hydrogen while 3% and 21% of O2 is reduced by thiosulfate, respectively. Under over-oxygenation conditions (pO2 = 10.5 and 12 mg/L), growth was correlated to high thiosulfate consumption whereas the expression of genes encoding hydrogenases was significantly downregulated and hydrogenase activity was null

Full textStable and isolable alkanethiolate-stabilized Pt nanoparticles (PtNP) were synthesized using the two-phase thiosulfate method with sodium S-alkylthiosulfate as ligand precursor. The mechanistic formation of octanethiolate-capped PtNP (Pt-SC8) from both sodium S-octylthiosulfate and 1-octanethiol ligands was investigated by using 1H NMR and UV-vis spectroscopy, which revealed the formation of different Pt complexes as the reaction intermediates. The partially poisoned PtNP with thiolate monolayer ligands was further investigated for the hydrogenation of various alkynes to understand the organic ligands-induced geometric and electronic surface properties of colloidal Pt nanoparticle catalysts. In addition, alkanethiolate-capped Pd nanoparticles (PdNP) were prepared using reversed thiosulfate addition method with S-octylthiosulfate as ligand precursor. Various synthetic conditions were applied to the modified two-phase method in order to control the average core size and surface ligand density. The obtained nanoparticles were characterized by 1H NMR, UV-vis spectroscopy, infrared spectroscopy (IR), thermogravimetric analysis (TGA), and transmission electron microscopy (TEM).

Full textThe Mercaptopyruvate Sulfurtransférase (MPST) and the Thiosulfate Sulfurtransférase (TST) are both key enzymes in cyanide detoxification. A deficiency of genetic origin in MPST or TST activity would lead to interindividual variability in susceptibility to cyanide and, consequently, could be involved in the pathogenesis of environmental diseases (ulcerative colitis and Crohn disease). The present work consisted first in the mutational screening of the MPST and TST genes in DNA samples from large groups of healthy individuals and patients, using a PCR-SSCP strategy and sequencing. This strategy allowed us to identify numerous polymorphisms in both genes. The functional consequences of some of the identified polymorphisms were then assessed by in vitro and in vivo assays. Our findings revealed for the first time the existence of a functional genetic polymorphism of MPST and TST. The clinical relevance of these genetic polymorphisms remains to be analysed

Full textThe purpose of this work is the selective extraction of Au, Ag, Cu and Zn from two types of galvanic sludge using a mixed process of sulfate roasting and sodium thiosulfate and ammonium thiosulfate leaching. In the experiments, the sludge was mixed with a sulfate promoter (sulfur, iron sulfate or pyrite) and treated by pyrometallurgical processes at temperatures up to 750◦C. At this stage, this agent is thermally oxidized, turning the furnace atmosphere and the metallic oxides into water-soluble sulfates. Afterward, the sulfates can be treated by leaching with water for recovery of Ag, Cu, Ni and Zn. The gold does not form sulfates in this reaction and was recovered through a second leaching stage using sodium and ammonium thiosulfate, an effective reagent and less harmful to the environment than cyanide. Different parameters as the sulfate promoter that achieves the highest recovery of metals, the proportion of galvanic sludge to sulfating agent, the temperature, the heating time in the oven and the leaching time were evaluated. Additionally, a comparison of gold recovery using cyanide versus sodium and ammonium thiosulfate was performed. The configuration that showed the best metal recovery included a 1:0.4 ratio of sludge to sulfur, an oven temperature of 550◦C, a roasting time of 90 minutes and a water leaching time of 15 minutes. Using these parameters, recovery rates of 75 % of the silver, 68% of the copper, 52% of Ni and 67% of the Zn were obtained. The sodium thiosulfate leaching resulted in a recovery of 78% of the Au, close to the values obtained using cyanide.

Full textSince the discovery of the ABCC6 gene in 2000, mutations are at the origin of PseudoxanthomeElastic (PXE), knowledge of genetics, pathophysiology, phenotypic characterizations have has mademajor advances, notably with the Discovery in 2013 of the fundamental role of Pyrophosphateinorganic (PPi) as a deficient anti‐calcifying factor in patients. The overall goal of this thesis was tostudy, from the cohort of patients at the center of PXE reference of the CHU d'Angers, differentaspects of cardiovascular phenotype (CV) of PXE. Thus, in a first work, we were able to show in thestudy GOCAPXE, that ectopic calcifications would be a active process that can be detected by imagingUsing a specific activity tracer Osteoblastic, 18‐sodium fluoride (18F‐NaF); that this process wasdetectable even before these calcifications are not visible by conventional imaging techniques; thatthis process was localized to areas usually injured in the PXE: flexion folds and neck for skin and thesuperficial femoral artery for the vessel. This technique should be validated in a study longitudinaland its role as a diagnostic biomarker In this way, monitoring and monitoring could be considered.The second work of this thesis was to study the morphological consequences and functional of achronic increase in blood pressure in PXE patients. This question was relevant because in theliterature, the question of a high blood pressure (hypertension) in PXE remains controversial. Wehave thus shown for the first time that in a model of HTA induced by the Deoxycorticosterone(DOCA)‐Salt in Abcc6‐/‐ this increase in blood pressure led to a CV remodeling with both fibrosis andcalcifications dystrophic. The results of this study suggest need for optimal control of blood pressurein patients. The third work of this thesis was to characterize a lesion of the internal carotid detectedwith high frequency in the Angevine cohort. We have could show that this abnormality washypoplasia of the Probably congenital internal carotid. In the patients of the angevine cohort, thislesion was associated with intracranial aneurysms but we have not found in association with theoccurrence of vascular accident brain. Thus, the results of this study invite practitioners supportingPXE patients to search for it systematically in the vascular balance of a PXE patient. If such a lesion isfound, vascular imaging Intracranial should be proposed to research Aneurysms and theirmanagement discussed in consultation multidisciplinary. Finally, the latest work has made it possibleto show that systemic treatment with Thiosulphate Sodium (STS), used in renal calciphylaxia, waseffective on the regression of arterial calcifications and skin in a young boy with a phenotype CVGravel resulting from the deleterious combination of several pathogenic genes of the PXE spectrumThis treatment would deserve be validated in a human therapeutic trial but also the demonstrationof its mechanisms of action in the Abcc6‐/‐murin model. We suggest using this treatment for severeand rapidly progressive PXE especially on the vascular plane.At the end of this thesis work, we showed that the ABCC6 gene was involved in vascular remodelingat both at the developmental level (Carotid Hypoplasia) but also acquired (Fibrosis, CardiacCalcification Dystrophic). We also showed that calcifications in PXE were tissues and locationsspecific, that these calcifications were active. Finally we have opened the door to a treatment ofsevere forms of PXE with Sodium Thiosulphate. An approach multimodal therapy targeting multiplemechanisms this would be useful to evaluate in future clinical trials
