Petrografia, suscetibilidade magnética e geoquímica do Granito Rio Branco, Província Carajás, sudeste do Pará, Brazil

The Paleoproterozoic Rio Branco stock intrudes the Archean Cruzadão biotite monzogranite. It occurs west of the Canaã dos Carajás city, close to the Sossego copper mine in the Carajás Province. It is constituted by undeformed and isotropic, hololeucocratic syenogranites, showing equigranular texture. The granite is formed essentially by perthitic alkali feldspar, quartz, and plagioclase, with additional variable amounts of chloritized biotite. Fluorite, allanite, and zircon are common accessory minerals, whereas pyrite and chalcopyrite are scarces. Albitization and subordinate greisenization are the main alteration processes that affected the granite. The secondary mineralogy is represented by albite, fluorite, topaz, chlorite, muscovite, siderophyllite, and iron oxides. Magnetic susceptibility values are systematically low and vary between 1.3 x 10-5 a 6.9 x 10-4 (SI). The Rio Branco Granite is metaluminous to peraluminous and shows high FeOt/(FeOt + MgO). It has geochemical affinities with ferroan, reduced A2-subtype granites. The rare earth element (REE) patterns are flat with little heavy REE fractionation and show accentuated negative Eu anomalies (Eu/Eu* = 0.08 - 0.13). These characteristics are typical of evolved granites, derived from volatile-enriched liquids responsible by the intense subsolidus hydrothermal alteration. The dating of the Rio Branco granite did not give conclusive results, but the obtained data, associated with geological evidence, suggest that it is of Paleoproterozoic age. The comparison between the Rio Branco granite and Paleoproterozoic A-type suites of the Carajás Province suggests that the Rio Branco granite has more affinity with the Velho Guilherme suite and, in lesser degree, with the Serra dos Carajás suite. On the other hand, is clearly different from oxidized A-type granites of the Jamon suite. Despite its similarities with tin-specialized granites, the Rio Branco Granite is not associated with tin mineralizations.Petrografia, suscetibilidade magnética e geoquímica do Granito Rio Branco, Província Carajás, sudeste do Pará, Brazil. O Granito Rio Branco é um stock paleoproterozoico intrusivo no biotita-monzogranito arqueano Cruzadão. Ocorre a oeste da cidade de Canaã dos Carajás, nas proximidades da mina de cobre do Sossego na Província Carajás. É constituído por sienogranitos não deformados e isotrópicos, hololeucocráticos, em geral de granulação média. A mineralogia é formada por feldspato alcalino pertítico, quartzo e plagioclásio. A biotita, intensamente cloritizada, é a principal fase máfica, acompanhada por flluorita, allanita, zircão, pirita e calcopirita como minerais acessórios. Albitização e, com menor intensidade greisenização, afetaram o granito, sendo a mineralogia secundária albita, fluorita, topázio, clorita, muscovita, siderofilita e óxidos e/ou hidróxidos de ferro. O Granito Rio Branco apresenta valores sistematicamente baixos de suscetibilidade magnética (SM) variando de 1,3 x 10-5 a 6,96 x 10-4 (SI). Geoquimicamente, é metaluminoso a peraluminoso, possui altas razões FeOt/(FeOt + MgO) e mostra afinidades com granitos ferrosos, tipo-A do subtipo A2. Os padrões dos ETR revelam um ligeiro enriquecimento de ETR leves em relação ao ETR pesados e anomalia negativa acentuada de Eu (Eu/Eu* = 0,08 - 0,13), resultando feição em "gaivota", característica de granitos evoluídos. O conjunto de dados obtidos demonstra o caráter evoluído do Granito Rio Branco e sua derivação a partir de líquidos reduzidos e enriquecidos em voláteis, causadores das transformações hidrotermais tardias. O estudo comparativo deste corpo com aqueles das suítes anorogênicas da Província Carajás sugere que o Granito Rio Branco possui maior afinidade com os granitos das suítes Velho Guilherme e, em menor grau, Serra dos Carajás. Por outro lado, é claramente distinto da Suíte Jamon. Embora apresente características similares às dos granitos especializados em estanho, não há mineralizações desta natureza associadas ao corpo

Especificidades de la reacción emocional en adolescentes y adultos jóvenes: un estudio psicofisiológico

El paso de una edad a otra depende de múltiples cambios en el desarrollo de procesos cognitivos y neurológicos; en el caso de habilidades afectivas y sociales, se ha demostrado que la adolescencia es una edad crítica para tomar decisiones, auto-monitorearse y realizar análisis social afectivo-emocional. El objetivo del estudio fue comparar la reacción emocional entre adolescentes y adultos jóvenes. El estudio se llevó a cabo en dos muestras, constituidas de un grupo control de adultos jóvenes y un grupo experimental de adolescentes, a los que se les solicitó responder el Manikí de Auto-Evaluación (SAM), en cinco opciones, medidas en escala Likert. Se les solicitó elegir entre tres pares de variables: agradable vs desagradable, activado vs anhedónico y controlado vs en-control. Se midió la reactividad autónoma en derivaciones: frecuencia cardiaca, conductancia de la piel, temperatura y la respuesta muscular abdominal. No se observaron diferencias estadísticamente significativas en la reacción autonómica entre grupos de edad. El análisis del Modelo Lineal General de Respuesta Conductual (GLM) mostró diferencias significativas en las respuestas entre los diferentes tipos de estímulos, observadas en la reactividad autónoma y las respuestas asignadas; sin embargo, no se encontraron diferencias significativas. Los datos indican un nivel similar en la reacción de reconocimiento y respuesta autónoma de valencia emocional entre adolescentes y adultos jóvenes. Estos hallazgos pueden indicar la misma reacción de autónoma para ambos grupos estudiados, lo cual conduce a la hipótesis sobre el desarrollo posterior en el procesamiento de afectividad en las estructuras principales nerviosas superiores, pero no en la reacción de dispositivo periféric

Evidence for the occurrence of starch degradation and cycling in illuminated Arabidopsis leaves

Trabajo presentado en la XXII Reunión de la Sociedad Española de Fisiología Vegetal / XV Spanish Portuguese Congress of Plant Physiology, celebrada en Barcelona (España), del 26 al 29 de junio de 2017Although there is a great wealth of data supporting the occurrence of simultaneous synthesis and breakdown of storage carbohydrate in many organisms, previous 13CO2 pulse-chase based studies indicated that starch degradation does not operate in illuminated Arabidopsis leaves. Here we show that leaves of gwd, sex4, bam4, bam1/bam3 and amy3/isa3/lda starch breakdown mutants accumulate higher levels of starch than wild type (WT) leaves when cultured under continuous light (CL) conditions. We also show that leaves of CL grown dpe1 plants impaired in the plastidic disproportionating enzyme accumulate higher levels of maltotriose than WT leaves, the overall data providing evidence for the occurrence of extensive starch degradation in illuminated leaves. Moreover, we show that leaves of CL grown mex1/pglct plants impaired in the chloroplastic maltose and glucose transporters display a severe dwarf phenotype and accumulate high levels of maltose, strongly indicating that the MEX1 and pGlcT transporters are involved in the export of starch breakdown products to the cytosol to support growth during illumination. To investigate whether starch breakdown products can be recycled back to starch during illumination through a mechanism involving ADP-glucose pyrophosphorylase (AGP) we conducted kinetic analyses of the stable isotope carbon composition (δ13C) in starch of leaves of 13CO2 pulsed-chased WT and AGP lacking aps1 plants. Notably, the rate of increase of δ13C in starch of aps1 leaves during the pulse was exceedingly higher than that of WT leaves. Furthermore, δ13C decline in starch of aps1 leaves during the chase was much faster than that of WT leaves, which provides strong evidence for the occurrence of AGPmediated cycling of starch breakdown products in illuminated Arabidopsis leaves.Peer reviewe

Isotope ratio mass spectrometric and genetic evidence for the occurrence of starch degradation and cycling in illuminated Arabidopsis leaves

Trabajo presentado en la XIII Reunión de Biología Molecular de Plantas, celebrada en Oviedo (España), del 22 al 24 de junio de 2016Substrate or “futile” cycles are metabolic cycles of synthesis and degradation of a compound resulting in ATP consumption and dissipation of energy. Although there is a great wealth of data supporting the occurrence of storage carbohydrate cycling in many organisms, previous 14CO2 pulse-chase studies indicated that starch degradation and cycling do not operate in illuminated Arabidopsis leaves. In this work we show that leaves of different starch breakdown mutants cultured under continuous light conditions accumulate higher levels of starch than WT leaves, which shows that starch degradation operates during illumination. To investigate whether starch breakdown products can be recycled back to starch during illumination through a mechanism involving ADP-glucose pyrophosphorylase (AGP) we conducted time-course analyses of the stable isotope carbon composition (δ13C) of starch in leaves of 13CO2 pulsed-chased wild type (WT) and AGP lacking aps1 plants. Maximum δ13C values of starch in aps1 leaves reached at the end of the pulse were exceedingly higher than those of WT leaves. Furthermore, δ13C reduction in starch of aps1 leaves during the chase was much more rapid than that of WT leaves. Notably, aps1/mex1 leaves impaired in the export of maltose derived from starch breakdown displayed a high-maltose phenotype. Results presented in this work provide strong evidence for the occurrence of simultaneous synthesis and breakdown of starch and the operation of starch cycling through a mechanism involving AGP in illuminated Arabidopsis leaves.Peer reviewe
