This article presents an analysis of facies of sedimentary sequences that occur as discontinuous bodies in the Jundiai region, west of the main Tertiary continental basins of the southeastern Brazil continental rift. Nine identified sedimentary facies, grouped into four associations, suggest the existence of an ancient alluvial fan system whose source area was the Japi mountain range (Serra do Japi). The deposits are considered Tertiary in age and chronocorrelated with those identified in the Atibaia region and at other sites up to 100 km east and northeast of Jundiai. The depositional model adopted to explain the filling of the basin proposes that the alluvial fans, which directly derive from the source area, terminated in a braided channel longitudinal to the basin axis that flowed to northwest, in a similar configuration to that of the present day. This basin may have extended to the Atibaia region or formed a set of small basins laterally contiguous to the faults associated with the rift. Such occurrences show that the formation of rift basins was broader than the area presently occupied by the main deposits. (c) 2005 Elsevier Ltd. All rights reserved.

Candida albicans is an opportunistic yeast that can cause oral candidosis through the formation of a biofilm, an important virulence factor that compromises the action of antifungal agents. The objective of this study was to compare the effect of rose bengal (RB)- and eosin Y (EY)-mediated photodynamic inactivation (PDI) using a green light-emitting diode (LED; 532 ± 10 nm) on planktonic cells and biofilms of C. albicans (ATCC 18804). Planktonic cultures were treated with photosensitizers at concentrations ranging from 0.78 to 400 μM, and biofilms were treated with 200 μM of photosensitizers. The number of colony-forming unit per milliliter (CFU/mL) was compared by analysis of variance and Tukey's test (P ≤ 0.05). After treatment, one biofilm specimen of the control and PDI groups were examined by scanning electron microscopy. The photosensitizers (6.25, 25, 50, 200, and 400 μM of EY, and 6.25 μM of RB or higher) significantly reduced the number of CFU/mL in the PDI groups when compared to the control group. With respect to biofilm formation, RB- and EY-mediated PDI promoted reductions of 0.22 log10 and 0.45 log10, respectively. Scanning electron microscopy showed that the two photosensitizers reduced fungal structures. In conclusion, EY- and RB-mediated PDI using LED irradiation significantly reduced C. albicans planktonic cells and biofilms. © 2013 Springer-Verlag London.

O 3º Consenso Brasileiro para pesquisa de autoanticorpos em Células HEp-2 (FAN) teve como propósito avaliar as dificuldades de implantação do 2º Consenso ocorrido no ano de 2002, discutir estratégias para controlar a qualidade do ensaio e promover a atualização das associações clínicas dos diversos padrões. MÉTODOS: Participaram do encontro em Goiânia nos dias 13 e 14 de abril de 2008 pesquisadores e especialistas de diversos centros universitários e laboratórios clínicos de diferentes regiões do Brasil, com o propósito de discutir e aprovar as recomendações que visam à melhor padronização, interpretação e utilização do ensaio pelos clínicos. Representantes comerciais de diferentes empresas produtoras de insumos para realização do teste de FAN foram convidados como ouvintes. RESULTADOS E CONCLUSÕES: O 3º Consenso enfatizou a necessidade do controle de qualidade em imunofluorescência dada a heterogeneidade de microscópios e reagentes disponíveis no mercado, promoveu adequações na terminologia utilizada para classificar os diferentes padrões e, finalmente, atualizou as associações clínicas com finalidade de facilitar cada vez mais o melhor uso do ensaio pelos clínicos.

The aim of this study was to evaluate citric acid application with or without chitosan on the maintenance of the quality of litchi 'Bengal'. It was used litchi on mature maturation stage. After selection, fruits were immersed for one minute on the solution of citric acid and chitosan: [1]Control - without immersion; [2] citric acid 300g L-1, [3] citric acid 300 g L-1 + chitosan 0,3%, [4]citric acid 300 g L-1 + chitosan 0,6%, [5] citric acid 600 g L-1, [6] citric acid 600 g L-1 + chitosan 0,3%, [7] citric acid 600 g L-1 + chitosan 0,6%. Chitosan of low molecular weight and deacetylation degree of 75,58% (Sigma - Aldrich®) were used. After immersion, fruits were put to drain the excess of solution. Then, they were stored in cool chamber at 5ºC, previously sanitized, for 20 days. The experiment was conducted following a completely randomized design, with a factorial scheme composed by seven coating solutions and five sampling dates. Every five days were evaluated: loss of fresh mass of fruits; color; content of anthocyanins and the activity of peel enzymes polyphenoloxidase and peroxidase. It was verified that the solution of citric acid 600 g L-1, associated or not to chitosan, and the combination of chitosan 0,3% to 300 g L-1 of citric acid were the most efficient to maintain the quality of litchi 'Bengal' for 20 days at 5ºC.

Di pari passo con l'espansione dell'industria dei videogiochi, la traduzione videoludica è andata evolvendosi con l'avanzamento tecnologico e l'impatto sempre più crescente di questo fenomeno culturale nella società. Questa recente tipologia di traduzione, chiamata localizzazione, combina elementi della traduzione di software con quella audiovisiva. In questo studio verrà analizzato il fenomeno della fan-translation, ovvero la traduzione autonoma di videogiochi da parte degli utenti, e verrà preso in esame il caso di Superfighters Deluxe, videogioco in fase di sviluppo dello studio indipendente MythoLogic Interactive.
