ABSTRACT: The Espinhaço rift system encompasses taphrogenetic events from the Statherian to Tonian in the São Francisco-Congo (SFC) paleocontinent. The magmatism is represented mainly by metamorphosed anorogenic granites and rhyolites with subordinate amphibolites. Zircon U-Pb (LA-ICPMS and SHRIMP) ages from felsic (1748 ± 3 Ma and 1740 ± 8 Ma) and mafic (1725 ± 4 Ma) rock samples, coupled with previous studies suggest that the Espinhaço igneous province erupted from ca. 1.79 Ga to ca. 1.70 Ga. The felsic rocks show characteristics of A-type magmas. The negative εHf(t) data for meta-rhyolite zircons (-12.32 to -17.58), the moderate δ 18 O values (7.02 to 7.98) and the REE patterns suggest crustal melting related to an extensional environment. The mafic rock shows negative values of εHf(t) in zircons (-4.05 to -8.25) and moderate δ 18 O values (5.56 to 7.87). The results disclose a basaltic magmatism in continental intraplate setting whose parental magma could have been derived from the subcontinental lithospheric mantle with contamination of crustal material. These data coupled with coeval Espinhaço magmatism and mafic dyke swarms found to the south of the Espinhaço rift system reinforce the evidence of a long-lived Statherian silicic large igneous province (SLIP) on the SFC paleocontinental block.

RESUMO: O Complexo Jequitinhonha é uma unidade sedimentar extensa da porção nordeste do orógeno Araçuaí, metamorfizada na transição entre as fácies anfibolito-granulito há cerca de 580-540 Ma. A unidade é composta por paragnaisses kinzigíticos com intercalações de grafita-gnaisse, quartzito e rochas calcissilicáticas. Dados U-Pb de zircão detrítico de uma amostra de quartzito e novos dados geoquímicos (nove amostras) e isotópicos (Sm-Nd) (dez amostras) são aqui apresentados. De maneira concomitante a dados previamente publicados, esses dados mostram que: (1) a geoquímica dos paragnaisses sugere uma afiliação do tipo margem passiva para as rochas metassedimentares; (2) zircões detríticos apresentam populações de idade U-Pb entre 0,9 e 2,5 Ga; e (3) dados isotópicos de Nd apresentam idades modelo T DM entre 1,6 e 1,8 Ga e εNd (575 Ma) ao redor de -7,5. Esses dados revelam uma mistura de fontes, envolvendo magmatismo de rift Criogeniano a Mesoproterozoico e o embasamento Paleoproterozoico-Arqueano do paleocontinente São Francisco-Congo, e sugerem uma forte correlação entre o Complexo Jequitinhonha e o Grupo Macaúbas, compondo a mais importante bacia precursora do orógeno Araçuaí. Além da natureza exclusivamente sedimentar do complexo, fatias ofiolíticas não foram encontradas na área, reforçando a interpretação da terminação ensiálica de um golfo e que o paleocontinente São Francisco-Congo não foi separado ao norte da região, agindo como uma única peça durante o Neoproterozoico.

ABSTRACT: The Jequitinhonha Complex of the northeastern Araçuaí orogen is an extensive sedimentary unit metamorphosed in the amphibolite-granulite facies transition around 580-545 Ma. The unit consists of Al-rich (kinzigitic) paragneisses with decametric intercalations of graphite gneisses and quartzites, and centimetric to metric lenses of calcsilicate rocks. A new detrital zircon U-Pb age spectrum is reported for a sample of quartzite, and whole-rock geochemical (major and trace elements, 9 samples) and Sm-Nd isotope data (10 samples) for Jequitinhonha Complex paragneiss. Together with published data these show that: (1) the geochemistry of paragneiss samples of the Jequitinhonha Complex are similar to those of passive margin sedimentary protoliths; (2) detrital zircon data yield U-Pb age populations between ca. 0.9 and 2.5 Ga; and (3) Sm-Nd TDM model ages range from 1.6 to 1.8 Ga and εNd(575 Ma) around -7.5. The data reveal a mixture of Cryogenian to Mesoproterozoic rift-related igneous rocks with the Palaeoproterozoic-Archaean basement rocks of the São Francisco-Congo palaeocontinent as the main source areas, and also support the correlation between the Jequitinhonha Complex and the passive margin units of the upper Macaúbas Group, constituting the precursor basin of the orogen. Our results, with the absence of ophiolites in the Jequitinhonha Complex, reinforce the interpretation that the São Francisco-Congo palaeocontinent was not divided to the north of the focused region, suggesting an ensialic termination of a gulf during the Neoproterozoic.

RESUMO Mudanças no uso do solo têm motivado pesquisas sobre a dinâmica de trocas radiativas e energéticas na Amazônia Brasileira que, por sua vez, geram demanda destas informações de superfície em escalas espaciais e temporais. Enquanto a medição destas trocas em torres micrometeorológicas fornece resultados pontuais, o sensoriamento remoto apresenta resultados acurados e de baixo custo para estimá-las em escala regional. Este estudo objetivou avaliar a distribuição espacial e temporal de estimativas de saldo de radiação e parâmetros biofísicos por sensoriamento remoto de diferentes usos do solo no sudoeste da Amazônia Brasileira. Foram selecionadas 04 áreas de solo coberto por floresta amazônica natural, floresta amazônica manejada, sistema silvipastoril e pastagem. O saldo de radiação, NDVI, índice de área foliar, albedo e temperatura radiométrica foram estimados pelo algoritmo SEBAL, usando imagens do sensor TM do satélite Landsat 5 em julho de 2009, 2010 e 2011. O NDVI, IAF, albedo e saldo de radiação apresentaram maiores valores na floresta natural, seguida por floresta manejada, sistema silvipastoril e pastagem. A temperatura radiométrica da superfície apresentou maiores valores para o sistema silvipastoril seguido por pastagem, floresta natural e floresta manejada.

ABSTRACT Changes in land use have motivated research on the dynamics of radiative and energy exchange in the Brazilian Amazon, which in turn cause demand for such data on the surface in spatial and temporal scales. While measuring these changes in micrometeorological towers provides punctual results, remote sensing provides accurate and low cost results to estimate them on a regional scale. This study aimed to evaluate the spatial and temporal distribution of estimates of net radiation and biophysical parameters from remote sensing in different land uses in southwestern Brazilian Amazon. Four sites were selected with soil covers by natural Amazon forest, Amazon managed forest, pasture and silvopastoral system. The net radiation and biophysical parameters (NDVI, leaf area index, albedo and radiometric temperature) were estimated by the SEBAL algorithm, using images from the Landsat TM sensor 5 in July of 2009, 2010 and 2011. The NDVI, LAI, albedo and net radiation were higher in natural forest, followed by managed forest, grassland and silvopastoral system. Radiometric surface temperature were higher in the silvopastoral system followed by pasture, natural forest and managed forest.

Os aços resistentes à abrasão da classe de 450 HB de dureza combinam a adição de carbono e de elementos de liga, visando à obtenção de uma microestrutura completamente martensítica e com elevada dureza ao longo de toda espessura da chapa. Porém, em virtude desta combinação, geralmente expressa pelo carbono equivalente, estes aços apresentam difícil soldabilidade. O objetivo deste trabalho foi avaliar a soldabilidade de dois aços resistentes à abrasão da classe de 450 HB de dureza, aos quais se distinguem o carbono equivalente e a espessura. Realizou-se ensaio Tekken para avaliação da susceptibilidade ao trincamento a frio induzido por hidrogênio e para determinação da temperatura de préaquecimento para soldagem. Além disso, foram confeccionadas juntas soldadas utilizando-se o processo MIG/MAG automático com diferentes aportes térmicos. As juntas soldadas foram caracterizadas mediante análise metalográfica e ensaios mecânicos. Verificou-se que nenhum dos aços necessitou de préaquecimento. Observou-se que a junta soldada do aço de menor carbono equivalente apresentou melhores resultados de dobramento, principalmente, quando utilizada a maior energia de soldagem. Este aço também apresentou os maiores valores de energia absorvida por impacto Charpy-V.

Abrasion-resistant steels of 450 HB hardness combine carbon and alloying elements addition aiming a completely martensitic microstructure and high hardness by all thickness of the plate. But due this combination, generally represented by carbon equivalent, these steels present a difficult weldability. The aim of this work was evaluate the weldability of two abrasion-resistant steels of 450 HB hardness, both with different carbon equivalent and thickness. It was conducted Tekken test to evaluate the susceptibility to cold cracking induced by hydrogen and to determinate preheating temperature for welding. Besides that, welded joints using automatic MIG/MAG welding process with different heat inputs were manufactured. The welded joints were characterized by metallographic analyses and by mechanical tests. It was verified that both steels do not need preheating temperature. It was noted that the welded joints from steel with smaller carbon equivalent presented better results in the bending test, principally when used the higher heat input. This steel still presented bigger absorbed energy from the CharpyV impact test.

A traqueobroncopatia osteocondroplásica (TO) é uma doença benigna rara, de causa desconhecida, caracterizada por numerosos nódulos submucosos sésseis, cartilaginosos e/ou ósseos, distribuídos pelas paredes ântero-laterais, projetando-se no lúmen laringotraqueobrônquico. Existem aproximadamente 400 casos relatados na literatura mundial. OBJETIVOS: Relatar e discutir 2 casos de TO com a revisão bibliográfica. MATERIAL E MÉTODO: Apresentação de 2 casos, com revisão bibliográfica realizada através dos bancos de dados do MEDLINE, LILACS, PUBMED. DESENHO DO ESTUDO: Estudo observacional, descritivo, relato de casos. CONCLUSÃO: Os sintomas são resultados de obstrução da via aérea, causando tosse seca, dispneia e infecções recorrentes do trato respiratório. A suspeita diagnóstica é feita pela endoscopia de vias aéreas (laringotraqueobroncoscopia), sendo a tomografia computadorizada do tórax/traqueia útil para documentar as características de lesões nodulares. O diagnóstico diferencial inclui a papilomatose, amiloidose e sarcoidose endobronquial, condrossarcoma, hamartoma e linfonodos paratraqueais calcificados. Não existe tratamento específico, porém o prognóstico é bom. A remoção cirúrgica é restrita aos quadros obstrutivos moderados e severos. Os otorrinolaringologistas devem estar atentos e incluírem a traqueobroncopatia osteocondroplástica na lista de diagnósticos diferenciais, quando frente aos sintomas sugestivos de doenças da via aérea superior e árvore traqueobrônquica.

Osteochondroplastic tracheobronchopathy (OT) is a rare benign disorder of the lower part of the trachea and the upper part of the main bronchus characterized by numerous submucosal calcified nodules, sessile, cartilaginous and/or osseous with laryngotracheobronchial lumen projection. There are less than 400 cases reported in the word literature. AIM: to report and discuss 02 cases of OT with a bibliography review. MATERIALS AND METHODS: we report on 02 cases with bibliography revision from MEDLINE, LILACS and PUBMED data. STUDY DESIGN: observational, descriptive, case reports. CONCLUSION: the symptoms result from airway obstruction, causing dry cough, dyspnea and recurrent respiratory tract infections. The diagnostic hypothesis is established by endoscopy of the upper airway (laryngo-tracheo-bronchoscopy), and the trachea/chest computed tomography is the best image exam to define tracheal nodule alterations. The differential diagnoses are papillomatosis, amyloidosis and sarcoidosis chondrosarcoma hamartoma and calcified paratracheal lymph nodes. There is no specific treatment and the prognosis is good. Surgery is restricted to moderate or severe airway obstructions. Otorhinolaryngologists must include OT in the differential diagnosis of cases of upper airway and tracheobronchial tree suggestive symptoms.

Helicobacter pylori is an important human pathogen that causes chronic gastritis and is associated with the development of peptic ulcer disease and gastric malignancies. The oral cavity has been implicated as a potential H. pylori reservoir and may therefore be involved in the reinfection of the stomach, which can sometimes occur following treatment of an H. pylori infection. The objectives of this paper were (i) to determine the presence of H. pylori in the oral cavity and (ii) to examine the relationship between oral H. pylori and subsequent gastritis. Gastric biopsies, saliva samples and dental plaques were obtained from 78 dyspeptic adults. DNA was extracted and evaluated for the presence of H. pylori using polymerase chain reaction and Southern blotting methods. Persons with gastritis were frequently positive for H. pylori in their stomachs (p < 0.0001) and there was a statistically significant correlation between the presence of H. pylori in gastric biopsies and the oral cavity (p < 0.0001). Our results suggest a relationship between gastric infection and the presence of this bacterium in the oral cavity. Despite this, H. pylori were present in the oral cavity with variable distribution between saliva and dental plaques, suggesting the existence of a reservoir for the species and a potential association with gastric reinfection.

Helicobacter pylori is a spiral-shaped Gram-negative bacterium. It colonizes the gastric mucosa of humans and persists for decades if not treated. Helicobacter pylori infection affects more than half of the world's population and invariably results in chronic gastritis. The cagA gene is present in about 60 to 70% of H. pylori strains; it encodes a high-molecular-weight protein (120 to 140 kDa) and several investigators have noted a correlation between strains that possess cagA and the severity of gastric mucosal inflammation. We examined the relation between cagA status in H. pylori strains and chronic gastritis with inflammatory processes in children from Marília, São Paulo, Brazil. One-hundred-twenty-one children were analyzed histopathologically and by polymerase chain reaction (PCR) to detect H. pylori and cagA. We then looked for an association between cagA presence and inflammatory infiltration. Using histology and PCR, we found 47% H. pylori positive infection; 29 children were diagnosed with chronic gastritis, while 28 showed normal mucosa by histopathological analysis. CagA presence was genotyped in both groups, and an inflammatory infiltrate was studied in all infected children with chronic gastritis. We found cagA strains in 20 of 29 (69%) children with chronic gastritis and 18 of 28 (64%) with normal mucosa, demonstrating a strong relationship between the strains and the inflammatory process. We found a positive association between an inflammatory process associated with H. pylori of cagA+ strains and chronic gastritis development.

Estudou-se o comportamento biológico e histopatológico de uma cepa genuínamente mariliense de Trypanosoma cruzi, isolada em 1997 através de xenodiagnóstico artificial. Vinte e cinco camundongos swiss foram infectados intraperitonealmente, sendo 11 utilizados para a realização da curva parasitêmica e observação da morfologia dos tripomastigotas e 14 foram sacrificados após o 17, 23, 30, 60 e 180 dias pós-infecção e coletados coração, esôfago, fígado, cólon, e músculo esquelético (fragmento da coxa direita) para análise histopatológica. Cultura em meio LIT foi realizada para análise de DNA. Os resultados mostraram predomínio de formas largas, baixa parasitemia com picos médios de 860 tripomastigotas/5mil de sangue ao redor do 20º dia de infecção. Nenhum camundongo morreu na fase aguda da infecção. Exame histopatológico mostrou poucos ninhos de amastigotas em coração, raros em músculo esquelético e cólon com discreto processo inflamatório. Comparada com a cepa Y, que foi isolada de uma paciente da mesma região, notamos diferentes características biológicas e comportamentais, porém a análise de DNA as coloca no mesmo grupo, demonstrando a proximidade dessas cepas.

The aim of this report was to study the biological and histopathological behavior of a Trypanosoma cruzi strain, which is found in the region of Marília. The strain was isolated in 1997, by artificial xenodiagnosis. Twenty-five swiss mice were intraperitoneally inoculated. Eleven were used for observation of parasitemia and trypomastigotes morphology and 14 were sacrificed after 17, 23, 30, 60 and 180 days post-infection. Heart, esophagus, liver, colon, and skeletal muscle (fragment of the right thigh) were collected for histopathological study. LIT culture medium was accomplished for DNA analysis. The results showed predominance of broad forms, low parasitemia with mean peaks of 860 trypomastigotes/5mul of blood of the 20th day of infection. No animal died in the acute phase of infection. Histopathological analysis showed several pseudocysts of amastigotes in heart, rare in skeletal muscle and colon with discreet inflammatory process. When Famema strain was compared with Y strain, which was isolated from a patient who lived in the same area, a distinct behaviour and biological characteristics were observed. However, DNA analysis placed them in same group, hence displaying the proximity of these strains.
