Abstract:
In our previous papers [1, 2] we considered the behavior of linear and crosslinked polyampholytes based on fully charged anionic monomer — 2-acrylamido-2-methyl-1-propanesulfonic acid sodium salt (AMPS) and cationic monomer — (3-acrylamidopropyl)trimethylammonium chloride (APTAC) in aqueous-salt solutions, swelling and mechanical properties. In the present paper we report the applicability of salt tolerant amphoter-ic terpolymers composed of AMPS, APTAC and acrylamide (AAm) in enhanced oil recovery (EOR). The amphoteric terpolymers of different compositions, particularly [AAm]:[AMPS]:[APTAC] = 50:25:25; 60:20:20; 70:15:15; 80:10:10 and 90:5:5 mol.% were prepared by free-radical polymerization, identified and their viscosifying ability with respect to reservoir saline water (salinity is 163 g⋅L-1) at 60 °C was tested. It was found that due to polyampholytic nature, the AAm-AMPS-APTAC terpolymers exhibited improved viscosifying behavior at high salinity water. As a result, the appropriate salt tolerant sample [AAm]:[AMPS]:[APTAC] = 80:10:10 mol.% was selected for polymer flooding experiments. Polymer flood-ing experiments on high permeable sand pack model demonstrated that only 0.5 % oil was recovered by am-photeric terpolymer. While injection of polyampholyte solution into preliminarily water flooded core sample resulted in the increase of oil recovery up to 4.8–5 %. These results show that under certain conditions the amphoteric terpolymers have a decent oil displacement ability.

Abstract:
SummaryAmphoterin (HMG1) is a 30-kD heparin-binding protein which is functionally associated with the outgrowth of cytoplasmic processes in developing neurones. Amphoterin has been shown to mediate adhesive and proteolytic interactions at the leading edge of motile cells. Recently it was shown that inhibition of amphoterin interactions with its cell surface receptor (RAGE) suppresses tumour growth and metastasis. In this work we have identified amphoterin polypeptide and its mRNA in human platelets. Amphoterin had a cytoplasmic localisation in resting platelets according to subcellular fractionation studies and immunogold electronmicroscopy. After platelet activation, part of amphoterin was associated with the external surface of plasma membrane. Externalisation of amphoterin during platelet activation was also detected in immunofluorescence studies. Amphoterin was detectable in human serum (0.2 ng/ml) but not in plasma. Resting platelets treated with PGI2 and forskolin bound to immobilised recombinant amphoterin independently of divalent cations. The binding induced a spicular morphology in platelets, and was effectively inhibited by heparin. Amphoterinbinding protein components on the platelet surface were not identified, but amphoterin bound to phosphatidylserine and sulfatide in lipid binding assays. Our results suggest that amphoterin is an endogenous protein in human platelets, which is exported to the cell surface during platelet activation. Interaction of amphoterin with the platelet surface may be mediated by sulfoglycolipids and phospholipids.

Abstract:
Amphoterin, a major form of HMG (high mobility group) 1 proteins, is highly expressed in immature and malignant cells. A role in cell motility is suggested by the ability of amphoterin to promote neurite extension through RAGE (receptor of advanced glycation end products), an immunoglobulin superfamily member that communicates with the GTPases Cdc42 and Rac. We show here that cell contact with the laminin matrix induces accumulation of both amphoterin mRNA and protein close to the plasma membrane, which is accompanied by extracellular export of amphoterin. A role for amphoterin in extracellular matrix-dependent cell regulation is further suggested by the finding that specific decrease of amphoterin mRNA and protein, using antisense oligonucleotides transfected into cells, inhibits cell migration to laminin in a transfilter assay whereas the oligonucleotides in the culture medium have no effect. Moreover, affinity-purified anti-amphoterin antibodies inhibit cell migration to laminin, supporting an extracellular role for the endogenous amphoterin in cell motility. The finding that amphoterin expression is more pronounced in cells with a motile phenotype as compared to cells of dense cultures, is consistent with the results of the cell migration assays. Our results strongly suggest that amphoterin is a key player in the migration of immature and transformed cells.

Abstract:
The release of amphoterin by murine erythroleukaemia cells exposed to the chemical inducer hexamethylenebisacetamide represents an essential step for the process of their terminal differentiation. Once exported in the culture medium, amphoterin undergoes limited proteolysis, catalysed by a serine proteinase also secreted by stimulated cells. The isolated proteinase is responsible for degradation of amphoterin, with the production of a 10-amino-acid-residue fragment, specifically retaining the cell-differentiation-stimulating activity of the native protein molecule. This peptide does not express other properties of amphoterin, such as protein kinase C-stimulating activity or systemic toxicity. These findings define a selective mechanism accounting for extracellular amphoterin functional maturation.

Abstract:
Chicken (Gallus gallus) pluripotent embryonic stem cells (ESCs) and primordial germ cells (PGCs) can be broadly applied in the research of developmental and embryonic biology, but the difference between amphoteric ESCs and PGCs is still elusive. This study determined the sex of collected samples by identifying specific sex markers via polymerase chain reaction (PCR) and fluorescence activated cell sorter (FACS). RNA-seq was utilized to investigate the transcriptomic profile of amphoteric ESCs and PGCs in chicken. The results showed no significant differentially expressed genes (DEGs) in amphoteric ESCs and 227 DEGs exhibited in amphoteric PGCs. Moreover, those 227 DEGs were mainly enriched in 17 gene ontology (GO) terms and 27 pathways according to Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis. Furthermore, qRT-PCR was performed to verify RNA-seq results, and the results demonstrated that Notch1 was highly expressed in male PGCs. In summary, our results provided a knowledge base of chicken amphoteric ESCs and PGCs, which is helpful for future research in relevant biological processes.

Abstract:
L'etude porte sur la comprehension des phenomenes responsables de la retention par le dioxyde de titane, d'ions en solution. On cherche notamment a correler la structure du solide a ses proprietes amphoteres en solution aqueuse. Un etat des connaissances sur la formation de gels d'oxydes mineraux et sur leur structure est donne. Differents modes de synthese de gels de dioxyde de titane sont presentes. Le materiau selectionne est caracterise par diffraction de rayons x, microscopie electronique, mesure de porosite par bet. Un modele a deux phases prenant en compte la nature poreuse du solide et permettant d'appliquer la loi d'action de masse est adopte. L'etude des proprietes amphoteres de l'oxyde est realisee par la technique de titrage potentiometrique. Les bouches a hysteresis observees entre les titrages aller et retour sont attribuees a la lenteur des reactions de neutralisation acido-basique. Les principales caracteristiques du solide (point isoelectrique, capacite de retention d'anions et de cations) sont ainsi determinees. Les valeurs trouvees sont confirmees par analyse par activation neutronique et microanalyse x. Un examen de la cinetique des reactions de neutralisation montre que, selon l'intensite de l'agitation de la suspension, l'etape limitant la vitesse peut etre soit la diffusion dans le film soit la diffusion dans la particule. Dans ce dernier cas, les coefficients moyens de diffusion des ions dans le solide sont evalues

Abstract:
Il n'existe à l'heure actuelle pratiquement pas de copolymères greffés à fonctions cationiques et/ou amphotères présentant une dégradabilité intrinsèque. L'objectif de cette thèse est de générer des composés répondant à ces critères à partir d'une méthode de modification chimique par voie anionique de poly(e-caprolactone) (PCL). A cette fin, deux stratégies principales ont été suivies à partir d'un même intermédiaire réactionnel, un macropolycarbanion dérivé de PCL. La première est fondée sur l'emploi du macropolycabanion en tant qu'agent nucléophile qui réagit avec de petites molécules organiques électrophiles. Ces réactions de substitution ont permis l'obtention de copolymères à base PCL possédant entre 10 et 15% de motifs substitués par des groupes cationiques (ammonium, phosphonium), ou hydrosolubilisants (amine, acide carboxylique). Ces squelettes PCL fonctionnalisés peuvent être utilisés pour effectuer des post-modifications (réactions de couplages, dérivation de fonctions). La seconde stratégie utilise le macropolycarbanion en tant que macroamorceur de polymérisation anionique. Ce type de réaction a été appliqué à des dérivés vinyliques (4-VP, N-VP), des dérivés acryliques (DMAEM, MAPEG), des dérivés acrylamides (DMA, DMAPMA) et des dérivés cycliques (NCA d'acides a-aminés) ce qui a permis d'obtenir des copolymères greffés hydrosolubles à chaîne principale PCL. Ces composés ont des structures partiellement dégradables et forment en solution aqueuse des objets de dimensions nanométriques. Enfin, l'utilisation d'un dérivé polyiodé de PCL en tant que macro-polyagent de transfert est abordée ce qui constitue une nouvelle méthode de polymérisation radicalaire contrôlée par transfert dégénératif d'iode permettant l'obtention de structures greffées.

Abstract:
De par leurs proprietes particulieres de surface les agents tensioactifs perfluoroalkyles ont trouve plusieurs applications aussi bien dans les domaines pratiques que dans les domaines biologiques ou biomedicaux. Le travail realise concerne la synthese et l'evaluation de nouvelles series de molecules tensioactives perfluoroalkylees qui ont la particularite de deriver des sulfobetaines f-alkylees. Tous les composes prepares sont caracterises par la presence: d'une chaine hydrophobe perfluoroalkylee et d'au moins une chaine hydrocarbonee plus ou moins longue ; d'une fonction sulfite ou sulfate ; d'une tete hydrophile cationique de type ammonium ou sulfonium quaternaire. Pour atteindre ces composes nous avons mis au point la synthese de nouveaux intermediaires reactionnels perfluoroalkyles les sulfates d'ethylene f-alkyles et les sulfites d'ethylene f-alkyles. L'etude de la reactivite de ces derniers vis-a-vis de divers composes mono- ou polyfonctionnels (amines, amines n-oxydes et sulfures) nous a permis de montrer que les sulfites et les sulfates perfluores sont de nouveaux intermediaires tres reactifs et que les reactions mises en uvre sont tres selectives et conduisent a chaque fois au produit attendu. Nous avons montre qu'il etait possible de synthetiser, de maniere selective, en une seule etape et selon des procedes simples de nouveaux tensioactifs amphoteres. Les rendements de ces syntheses sont satisfaisants et varient en moyenne de 60 a 95%.

La recherche vise à proposer des membranes pour des dispositifs électrochimiques capables d'atteindre le bon compromis en terme de conduction ionique, de stabilité et de longue durée de vie pour une haute efficacité.Nous avons réalisé des membranes échangeuses des protons, d'anions ou amphotères à base de polymères aromatiques stables fonctionnalisés. Des groupes sulfonique on été introduit sur la squelette du PEEK, des groupes d'ammonium sur le PEEK et le PSU ou le deux au même temps pour échanger ensemble des protons et des anions.L'optimisation continue des paramètres de synthèse, le choix des différents polymères et/ou des groupes de fonctionnalisation et l'amélioration des procédures et des traitements des membranes coulée, a conduit à de bons résultats en termes de conductivité ionique, sélectivité et stabilité.L'étude des principaux paramètres des membranes démontre une stabilité thermique entre 140 et 200 ° C selon la membrane sélectionnée, un comportement mécanique caractérisé par une résistance à la traction et un module d'élasticité élevée et un relativement faible ductilité, influencé par le niveau d’ hydratation de la membrane ou l éventuelle présence de cross-link. En optimisant le degré de fonctionnalisation et les types de groupes de fonctionnalisation, nous avons obtenu une accordable absorption d'eau, une conductivité ionique élevé pour différent ions (jusqu'à ≃ 3 mS / cm pour le polymère conducteurs des anions) et une perméabilité aux ions vanadium très faible (applications dans RFB) jusqu'à ≃ 10-10 cm2/min, ce qui est bien au-dessous des données typiques de la littérature et un paramètre très important pour applications technologiques
The research aims to propose membranes for electrochemical devices alternative to the commercial ones able to reach the right compromise in term of good ionic conduction, stability and long life time for an high efficiency. We realized proton exchange, anion exchange and amphoteric membranes based on stable functionalized aromatic polymers (PEEK, PSU). We thus introduced sulfonic groups on a PEEK backbone to exchange protons or ammonium groups on PEEK and PSU to exchange anions. We also realized amphoteric membranes able to exchange at the same time both kinds of ions. The continuous optimization of synthesis parameters, the choice of different polymers and/or functionalization groups and the improvement of casting procedures and treatments of membranes, led to good results in terms of ionic conductivity, selectivity and stability.The study of the main parameters of the synthesized membranes demonstrates a thermal stability between 140 and 200°C depending on the selected membrane, a mechanical behavior characterized by a high elastic modulus and tensile strength and a relatively low ductility strongly influenced on the degree of hydration of the membrane as well as the eventual presence of cross-linking. Working on the degree of functionalization and the type of functionalizing groups, we obtained a tunable water uptake, an elevated ionic conductivity for different ions (up to ≃ 3 mS/cm for anionic conducting polymers) and a very low ion permeability (vanadium ions for RFB applications) down to ≃ 10-10 cm2/min, which is much below typical literature data for cation- and anion separation membranes and a challenge parameters for technological applications

Abstract:
O monocloroacetato de sódio (MCAS) e o dicloroacetato de sódio (DCAS) são compostos tóxicos e irritantes ao ser humano e nocivos ao meio ambiente, sendo impurezas indesejáveis na cocoamido propil betaína (CAPB), que é um surfactante anfótero utilizado em produtos de consumo dos segmentos cosmético e domiciliar. Diante dos requisitos de concentração em nível de mg/kg exigidos pelos órgãos reguladores de saúde do governo, tornou-se mandatório o emprego de metodologia com limite de quantificação, precisão e exatidão adequados aos rígidos controles de processo pelos fabricantes da CAPB, bem como, dispor de técnicas convencionais com poder de resolução e proficiência pelo controle de qualidade e neste contexto inseriu-se a cromatografia a gás. Neste estudo foram estabelecidos os procedimentos analíticos que definiram as melhores condições para identificar e quantificar as impurezas MCAS e DCAS na matriz CAPB por meio da cromatografia a gás. A preparação das amostras consistiu da derivação das impurezas MCAS e DCAS a ésteres etílicos e a extração líquido-líquido em hexano para separar dos demais constituintes da matriz. Os modos de detecção acoplados à cromatografia a gás foram a ionização pela chama (GC/FID), a captura de elétrons (GC/ECD) e a espectrometria de massas (GC/MS). A validação comprovou que as metodologias são lineares entre 4 e 50 mg/kg com recuperação de 70 a 120%, apresentam limites de quantificação inferiores a 10 mg/kg e produziram médias e incertezas similares na amostra examinada, constituindo-se alternativas para a determinação de cloroacetatos em betaínas.
The sodium monochloroacetate (MCAS) and the sodium dichloroacetate (DCAS) are toxic and irritating compounds to humans and harmful to the environment, being undesirable impurities in cocoamidepropyl betaine (CAPB), which is a amphoteric surfactant used in consumer products of cosmetic and household segments. Considering the content requirements at level mg/kg defined by governmental health agency, became mandatory the use of analytical methods with appropriate precision, accuracy and quantification limit to rigid process controls by CAPB manufacturers, as well as, to have available conventional techniques with good resolution and proficiency for quality control staff and in this context was inserted the gas chromatography. In this study, the analytical procedures were established to define the best conditions to identify and quantify the impurities MCAS and DCAS in CAPB matrix by gas chromatography. The sample preparation consisted of MCAS and DCAS derivation to ethyl esters and liquid-liquid extraction in hexane to separate them from the other constituents of matrix. The detection modes coupled to gas chromatography were the flame ionization (GC/FID), electron capture (GC/ECD) and mass spectrometry (GC/MS). The validation ensured that the methodologies are linear between 4 and 50 mg/kg with recovery 70 to 120%, presents quantification limits less than 10 mg/kg and produced similar averages and uncertainties in the examined sample, constituting an alternative for determination of chloroacetates in betaines.

Abstract:
Amphoterism is the phenomenon where some metallic oxides can exist and react in both acidic and basic forms. This work therefore looked at the possibility of using amphoteric oxides for constructing Floating Production Storage Offloading hulls with a view to combating corrosion. The focal point of the work was on the detailed use of experimental model and statistical analyses to obtain results necessary to support the fact enunciated. In the experimentation conducted, it was noticed that the aluminium used in ship building corroded 100 times slower than steel. During the first year of operation, steel alloy corroded at a rate of 120mm/year whereas aluminium deteriorates at a rate of 1mm/year. This implies that use of aluminium oxide for Floating Production Storage Offloading hull would entail less downtime for dry-docking. The fact that the procedure of formulating a statistical model for corrosion of Floating Production Storage Offloading hull has not been much documented in open literatures makes this effort worth-while at this point.
