Full textThe aim of this work was to understand the molecular mechanism of translation and the mechanism of translation termination, in particular. Cleavage of peptidyl-tRNA and peptide release terminates translation of mRNA on the ribosome. In prokaryotes, three release factors (RFs) are involved in this process. RF1 and RF2 recognise the three stop codons on mRNA and induce hydrolysis of the ester bond in peptidyl-tRNA. RF3 accelerates the rate of RF1 and RF2 recycling between ribosome in a GTP-dependent manner. We have clarified the mechanism of action of peptide release factor RF3. In the cell, free RF3 is in the GDP conformation. When RF3∙GDP binds to ribosome in complex with RF1 or RF2, these ribosome complexes act as guanine exchange factors for RF3 by inducing rapid dissociation of GDP. If, and only if, the peptide has been removed from tRNA, GDP is quickly replaced by GTP. Binding of GTP to RF3 induces a conformation of the factor with high affinity for the ribosome, which forces RF1 or RF2 to rapidly dissociate. Subsequent hydrolysis of GTP on RF3 induces a factor conformation with low affinity for the ribosome and rapid release of RF3∙GDP. It was further shown how the position of peptidyl-tRNA on the ribosome and the presence or absence of its peptide regulates the binding and GTPase activity of translation factors IF2, EF-G and EF-Tu. The result explains how idling GTPase hydrolysis and negative interference between different translation factors are minimized in living cells. The present biochemical observations, in conjunction with cryo-EM results, lead to new proposals for the role of hybrid sites in translocation of tRNAs, recycling of RF1 and RF2 by RF3 and recycling of post-termination ribosomes back to a new round of initiation.

Full textFor decades, Ivry-sur-Seine was seen as a model Communist stronghold within the Paris ‘Red Belt'. The particular brand of communism practiced by Ivry's municipal government had turned its working-class housing estates into laboratories directed towards the production of a singularly efficient political affiliation system. Until the watershed of the 1980s, electoral results for the various communist representatives in the Maurice Thorez and Yuri Gagarin housing estates seemed to corroborate this. The decline of the politicization model born of industrialization as well as the generation gap have radically undermined the conditions in which a socio-political affiliation system favourable to communist representatives can survive, however. The choice of a long-term ethnographic approach can give us insight into this phenomenon. Since the middle of the 1980s, the contrasting socio-political evolution of the Thorez and Gagarin allotments has testified to the intra-municipal disruption that affects this type of suburban Parisian territory. In the Yuri Gagarin area, the majority of older working-class families have been replaced with a new working-class population essentially stemming from immigration. Often unaware of the rich history of communism in their municipality, these new generations are sometimes actively involved in the challenging of the older local political authority. Downtown, on the contrary, the descendants of the families that were closest to the local party machine have maintained residency in the Maurice Thorez area. Community links have survived around a local political “endocracy” that works relatively independently from the older partisan frame. For many middle-class families living in Ivry, the maintenance of a certain communist authority makes it easier to accept the social, political, and electoral transformations of contemporary municipal communism

Full textThe Pitinga mine (Sn, Nb, Ta and cryolite) is a world-class deposit associated with albite-enriched facies of the Madeira granite (1.83 Ga). This study deals on RRE and Y minerals in order to contribute to the understanding of the albite-enriched system evolution and evaluate preliminarily the potential for exploitation of these elements as coproduct. The REE grades in the core albite-enriched granite ranges from 180 to 12168 ppm (average 1725 ppm) and the Y grades ranges from 35ppm to 7846 ppm (average 825 ppm). In the border albite-enriched granite, the grades are 30% lower than in the core facies. Xenotime is the principal REE and Y ore mineral. It occurs disseminated (<0.5% in the core albite-enriched granite and <1% in the transitional albite granite) and like agglomerates of centimeter crystals in the pegmatitic albite-enriched granite on central part of the core albite-enriched granite. This mineral has high contents of HREE (17% to 24% in all), especially in the core albiteenriched granite xenotime (22% to 24%). Y in xenotime ranges form 19% to 8%; U, Th and Ca contents are low and a strong positive correlation between Si and Th is related to the thorite type substitution: Y3+ + P5+ = Th4+ + Si4+. The F concentrations ranges from 0,11% to 5,10% in the core albite-enriched granite xenotime, from 0,64% to 1,40% in the pegmatitic albite-enriched granite xenotime and from 0 to 0,68% in the transitional albite-enriched granite xenotime. Its incorporation in the xenotime structure occurred through the substitutions: [PO4]5- + (Th)4+ = [ . (F)4]4- + (Y, ETR)3+ and [PO4]5- + (Ca)2+ = [ . (F)4]4- + (Na)1+. The shortening of the c parameter, the lowest value ever found in natural xenotime, is related to the high REE content and especially to the Yb and Er abundance. Reversed relations with the YPO4 synthetic pattern and modifications on the a and c parameters in different proportions are related to the replacement of O by F. The chemical data determined an age of 1,838 +/- 145Ma. Gagarinite occurs associated to the core albite-enriched granite, in the lower part of the cryolitic zone B, where it could be a mineral ore REE and Y in addition to xenotime. Its composition is Na0,24Ca0,58Y1,01(ETR)0,39F5,81. It has abundant inclusions (<1 mm) of fluocerite (Ce0,53-0,66 La0,09-0,26 Nd0,08-0,26 Sm0,01-0,04 Eu0,01 Y0-0,03 F3,3-4,14) with crystallographic parameters (a= 5.97 to 5.99 and c= 3.50 to 3.53) modified compared to synthetic standards by the significant amounts of La and Nd in solid solution. The origin of these inclusions was investigated in detail by various techniques (TEM, SEM, FI). It is most likely formed by exsolution of REE with radius greater than that of Sm, from an initial metastable gagarinite (Na0.23Ca0.53REE0.99Y0.48F7.69). Waimirite is a new mineral that occurs associated with a kaolinite polytype in later veins. It is characterized as a Y fluoride [(REE, Y)F3] in which the predominant REE are the HREE (especially Dy); Ca and Na occur in small quantities. The tetrad effect (more frequent in the third tetra) occurs in the core albiteenriched granite, border albite-enriched granite, hypersolvus granite and in the massive cryolite deposit, and is associated with HREE enrichment in the late facies. In the core albiteenriched granite the total tetrad effect (TET) is 2.48 and the third tetra (NT3) is 1.87. Portions of this rock less enriched in REE have effect in the first tetra (ES1) of 1.34. Samples extremely rich in REE rarely present tetrad effect, meaning that this phenomenon is not only related with the abundance of these elements. There is no statistically significant correlation between tetrad effect and Eu and Ce anomalies, LREE / HREE and F.

Minerals bearers of elements of the rare (ETRs) lands in Albita Granite of Nucleus of the plúton Wood (mine of Pitinga) they were studied using analytical techniques for DRX, MEV and petrografica, having been accomplished structural geological mapping of the digging of the mine with the intention of evaluating the space distribution and structural control on the occurrence of dikes pegmatites and veins with fluorita. The analyses petrográficas were accomplished seeking to understand the mineral association and the processes put upon as deformation and/or alteration hydrothermal. Analyze them of diffraction of rays X (DRX) accomplished in the affected granite by process hydrothermal, that modified the texture and composition of the rock, to identify mineral argilo and minerals related to the event hydrothermal and with occurrence of elements rare (ETR) lands, and transition (ítrio) elements. The focus of the research consists of determining the style of occurrence of the minerals bearers of ETR and transition elements and the related minerals associations the these to understand the processes formators and to postulate a model that explains the presence of these minerals in the granite. The results of the research showed that mine accessory common in granites as zircon, apatite are accompanied of exotic minerals as, cryolite, xenotime, torite, riebeckite, pyrochlore and polilitionite, mainly of origin magmatic and late derived magmatic of the crystallization of two pulses discreet granitic, registering structure in banding compositional of flow magmatic that controls the space distribution of these mines, that exhibit organization and they link with minerals albita, K-feldspar and quartz, deformed for mechanisms developed in high temperature. Fluid late magmatic formed dikes with texture pegmatite and composition granitic, whose minerals associate to zircon, criolita, xenotime, genthelvita, riebeckite, epidote, pyrochlore, gagarinite, polilitionite. It increases that happened later Pulse of fluids constituted by cassiterite, torite and oxides of iron. And pulses constituted by fluorite, allanite, fluocerite, chlorite and galena forming veins. Dikes and veins spatially present pattern of compatible orientation with model of shearing guided dextral 260° and close dive of 60° for associated N her conjugated synthetic with attitude dominant close 110° dive of 70° for S and the structure tensile with close attitude of 340° and I dip subvertical for W. This model controlled the placement of the pluton, and the development of structures with occurrence of the minerals bearers of ETRs. The fluids rich hydrothermal in ETR percolated the albite granite and they generated argilo mineral product of the alteration of the same. The structural pattern and the identified mineral association, they attest the coherence with that the minerals bearers of ETRs are distributed in the albite nucleus granite.
Minerais portadores de elementos das terras raras (ETRs) no Albita Granito de Núcleo do plúton Madeira (mina de Pitinga) foram estudados usando técnicas analíticas por DRX, MEV e petrografica, tendo sido realizado mapeamento geológico estrutural da cava da mina com o intuito de avaliar a distribuição espacial e controle estrutural sobre a ocorrência de diques pegmatíticos e veios com fluorita. As análises petrográficas foram realizadas visando entender a associação mineral e os processos sobrepostos como deformação e/ou alteração hidrotermal. As analises de difração de raios X (DRX) realizadas no granito afetado por processo hidrotermal, que modificou a textura e composição da rocha, para identificar argilo minerais e minerais relacionados ao evento hidrotermal e com ocorrência de elementos terras raras (ETR), e elementos de transição (ítrio). O foco da pesquisa consiste em determinar o estilo de ocorrência dos minerais portadores de ETR e elementos de transição e as associações minerais relacionadas a estes para entender os processos formadores e postular um modelo que explique a presença destes minerais no granito. Os resultados da pesquisa mostraram que minerais acessórios comuns em granitos como zircão, apatita estão acompanhados de minerais exóticos como, criolita, xenotima, torita, riebeckita, pirocloro e polilitionita, principalmente de origem magmática e tarde magmática derivada da cristalização de dois pulsos graníticos discretos, registrando estrutura em bandamento composicional de fluxo magmático que controla a distribuição espacial destes minerais, que exibem organização e se relacionam com minerais albita, K-feldspato e quartzo, deformados por mecanismos desenvolvidos em alta temperatura. Fluido tarde magmático formou diques com textura pegmatítica e composição granítica, cujos minerais associam-se a zircão, criolita, xenotima, genthelvita, riebeckita, epidoto, pirocloro, gagarinita, polilitionita. Cresce que ocorreu Pulso de fluidos mais tardio constituído por cassiterita, torita e óxidos de ferro. E pulsos constituídos por fluorita, allanita, fluocerita, clorita e galena formando veios. Diques e veios espacialmente apresentam padrão de orientação compatível com modelo de cisalhamento dextral orientado 260° e mergulho próximo de 60° para N associado a conjugado sintético com atitude dominante 110° mergulho próximo de 70° para o S e a estrutura tensiva com atitude próxima de 340° e mergulho subvertical para W. Este modelo controlou a colocação do plúton, e o desenvolvimento de estruturas com ocorrência dos minerais portadores de ETRs. Os fluidos hidrotermais ricos em ETR percolaram o albita granito e geraram argilo minerais produto da alteração do mesmo. O padrão estrutural e a associação mineral identificada, atestam a coerência com que os minerais portadores de ETRs se distribuem no albita granito de núcleo.
