    At Garimpo Porquinho (Tapajós Province, Brazilian Amazon) gold-bearing quartz veins containing sulfides occur in a narrow zone affected by hydrothermal alteration. The artisanally mined veins are exposed in a saprolite zone extending down at least 9 m to the fresh rock and are covered by a 1 m thick residual soil. Lateral gold dispersion in the saprolite is not noticeable whereas in the soil gold dispersion has been observed as far as 2 m from the vein. Trace metals associated with gold include Ag, Bi, As and Sb. Copper and lead, present in sulfides, can also indicate the presence of gold. The study of gold particles in different levels of the profile shows that gold has been affected by weathering. In the upper levels of the profile, particles are smaller, more rounded and pitted by dissolution. Grains of primary gold containing up to 20% Ag are commonly exhibit silver-poor rims which may penetrate deep into the grain. The interface between the Ag-poor rims and the interior is very sharp. Such gold-rich rims likely formed by self-electrorefining of electrum grains during weathering.No Garimpo Porquinho (Província Tapajós, Amazônia brasileira) veios de quartzo e sulfetos portadores de ouro ocorrem em uma zona estreita afetada por alteração hidrotermal. Sobre a mineralização primária ocorre uma cobertura de saprolito de cerca de 9 m de espessura, capeada por solo de 1 m de espessura. No saprolito não há dispersão lateral do ouro. No solo, no entanto, ocorre dispersão lateral do ouro até pelo menos 2 m a partir do veio. Os principais elementos farejadores são Ag, Bi, As e Sb. Cobre e chumbo, presentes nos sulfetos, podem também indicar a presença de ouro. O estudo das partículas de ouro em diferentes níveis do perfil de alteração mostrou que o ouro foi afetado pelo intemperismo. Nos níveis superiores do perfil as partículas são menores, possuem formas arredondadas e suas superfícies apresentam minúsculos orifícios característicos de dissolução. Observa-se que grãos de ouro primário (20% Ag) exibem comumente bordas empobrecidas em prata que podem penetrar fundo no grão. A interface entre as bordas empobrecidas em prata e o interior é brusca. A formação desses grãos pode ser atribuída ao processo de auto-refinamento eletrolítico dos grãos de electrum durante o intemperismo

    Interaction of intestinal microorganisms with the human host in the framework of autoimmune diseases

    Autoimmune diseases, such as systemic lupus erythematosus (SLE), are caused by a complex interaction of environmental-, genetic-, and sex-related factors. Although SLE has traditionally been considered independent from the microbiota, recent work published during the last 5 years suggests a strong connection between SLE and the composition of our gut commensals as one of the main environmental factors linked to this disease. Preliminary data have evidenced that (i) interaction of certain microbial-derived molecules with specific cell receptors and (ii) the influence of certain commensal microorganisms over specific immune cell subsets plays an important role in the pathogenesis of SLE and SLE-like diseases. In addition, epigenetic changes driven by certain microbial groups have been recently proposed as an additional link between gut microbiota and SLE. As immune responses elicited against commensal bacteria are deeply dependent on the composition of the latter, and as microbial populations can be modified by dietary interventions, identifying the precise gut microorganisms responsible for worsening the SLE symptoms is of crucial importance for this and other SLE-related diseases, including antiphospholipid syndrome or lupus nephritis. In this minireview, the current knowledge on the relationships between microbes and SLE and SLE-related diseases is compiled and discussed.This research was funded by Grants AGL2013-44039-R and AGL2010-14952 from the Spanish “Plan Estatal de I + D + I”.

    This work evaluated the levels of 5-aminolevulinic acid (ALA) in the liver of rats exposed to different doses of HCB (25,50, and 100 mg/kg b.w. for 4 weeks) and correlated them with lipid peroxidation parameters. Levels of ALA were determined by high-pressure liquid chromatography after derivatization with acetylacetone and formaldehyde, followed by fluorescence detection. The methodology was carefully validated, nonetheless hepatic levels of ALA in all animals treated or not were below the detection limit of the method (2.27mg of ALA/g liver). On the other hand, lipid peroxidation, evaluated as thiobarbituric acid reactants production and chemiluminescence was found significantly increased in the livers of all treated rats, in comparison with control values (pEste trabalho avaliou os níveis de ácido delta-aminolevulínico (ALA) em fígado de ratos expostos a diferentes doses de hexaclorobenzeno (HCB) (25, 50 e 100 mg/kg de peso corpóreo) durante 4 semanas e correlacionou com os parâmetros de peroxidação lipídica. Os níveis de ALA foram determinados por cromatografia líquida de alta eficiência após derivatização com acetilacetona e formaldeído, seguida de detecção de fluorescência. A metodologia foi cuidadosamente validada, apesar disso, os níveis hepáticos de ALA em todos os animais tratados ou não foram abaixo do limite de detecção do método (2,27 mg de ALA/ g de fígado). Por outro lado, para a peroxidação lipídica, avaliada como produção de reagentes ao ácido tiobarbitúrico e quimiluminescência, os resultados foram significativamente elevados em todos os animais tratados em comparação com os do grupo controle (

    Routes for Specialization in Psychology throughout Europe

    Get PDF
    The specialization of psychology helps to delineate fields in the practice of psychology. When establishing professional qualification criteria, associations seek to promote, in their members, scientific skills and knowledge considered fundamental for the practice of psychology in a given area. The present study reports on a survey of the member associations of the European Federation of Psychologists Associations (EFPA). The survey inquired about: (a) the initial requisites for entering the profession and (b) additional requisites for specialization. Of the 37 associations contacted, 14 replied and we retrieved the information of 12 associations from their official websites. The results indicate that specialization is widespread throughout Europe and is independent of the regulation of the profession. In almost half of the countries considered, the specialization process is completed in universities—it is frequently associated with the postgraduate level of the EuroPsy—and relies on conventional learning methods. The number of existing specialties in psychology is very high, but the traditional areas (clinical and health, education, and social/organizational) are more prevalent. The results are discussed in light of the advantages, but also the challenges posed by the specialization in psychology. A continuous model of the specialization of psychology is proposed with two stages: broad and advanced psychology area
