Sedimentação na bacia do Pantanal Mato-Grossense, Centro-Oeste do Brasil

The Pantanal is a Quaternary sedimentary basin located at the left margin of the Upper Paraguay River, west-central Brazil. Basin infilling was mainly by siliciclastic sediments and the stratigraphic succession exhibits an overall finingupward pattern. The depositional system tract is composed by a large meandering fluvial plain and several marginal alluvial fans, being the Taquari megafan the most striking feature. The present landscape is a complex tropical wetland, with geomorphic features derived from the present conditions and other inherited from successive Pleistocene and Holocene climates. During the Pleistocene, the sedimentary environment was dominated by braided alluvial fans, the original geometry of which is preserved as relict forms, permitting remarkable patterns of distributary paleochannels to be easily recognized in satellite images. Eolian processes were active in some abandoned lobes, contemporaneously with sedimentation in active fan lobes. Closed ponds bordered by lunette sand dunes, originally salt pans produced by eolian deflation, are relict eolian landforms in the Pantanal landscape. Eolian processes were probably more effective at the glacial maximum. Landscape has been changing in the Pantanal area since the end of the Pleistocene in adaptation to a more humid and warmer environment prevailing during Holocene. Initiation of the modern wetland has occurred during the Pleistocene / Holocene transition, with the change to a more humid climate and the individualization of lacustrine systems. The modern Pantanal wetland is a vast expanse of poorly drained lowlands that experiences annual flooding from summer to fall months. Although climatic fluctuations have occurred during all the Holocene, the alluvial fans have remained active depositional systems and lobes were formed by progradation and abandonment. Abandoned lobes were subjected... (Complete abstract click electronic address below)

Tempo para acesso ao tratamento do câncer de mama no Distrito Federal, Brasil Central

PURPOSE: To analyze the time between the first symptom and treatment in patients treated for breast cancer in public hospitals in the Federal District. METHODS: This was a cross-sectional analysis. We interviewed 250 women diagnosed with breast cancer treated in six hospitals of the State Department of Health of the Federal District from November 2009 to January 2011. The time intervals studied were the time between the detection of the symptoms and treatment subdivided into intervals until and after the first medical appointment. The variables were: age, menopausal status, color, educational level, average monthly household income, origin, reason for the initial consultation, staging, tumor size, laterality, metastasis to axillary lymph nodes, neoadjuvant chemotherapy, and type of surgery. The Mann-Whtney test was used to assess the association of these variables with the time intervals until treatment. RESULTS: The mean age was 52 years, with a predominance of white women (57.6%), from the Federal District (62.4%), with a family income of up to 2 minimum wages (78%), and up to four years of schooling (52.4%). The staging of the disease ranged from II to IV in 78.8% of the women. The time between the first symptom and treatment was 229 days (median). After detection of the first symptom, 52.9% of the women attended a consultation within 30 days and 88.8% took more than 90 days to start treatment. Women with elementary school education had a greater delay to the start of treatment (p=0.049). CONCLUSIONS: There was a significant delay to start treatment of women with breast cancer in public hospitals of the Federal District, suggesting that efforts should be made to reduce the time needed to schedule medical appointments and to diagnose and treat these patients.

Avaliação ultrassonográfica do bulbo ocular em cães submetidos à facoemulsificação com ou sem implante de lente intraocular

This study aimed to describe and compare the ultrasonographic alterations in dogs' eyes submitted to facectomy with or without intraocular lens implant (IOL), to assist in the diagnosis of possible alterations related to the surgical procedure and IOL implantation. Nineteen dogs with cataract (21 eyes) were submitted to phacoemulsification and late postoperative evaluation (at five years). The animals were initially submitted to complete ophthalmological exams which preceded the sonogram. Dogs were divided in three groups: (CA) aphakic dogs (n= 11); (PP) pseudophakic dogs with implantation of two IOLs in piggyback (n=5) and (PL) pseudophakic dogs with implantation of a veterinary IOL (n = 5). The ultrasound was carried under the administration of a topic local anesthetic, with a multi frequency linear transducer of 10 MHz. Biometric eye measurements were also performed. The clinical alterations observed were IOL dislocation, retinal detachment, asteroid hyalosis, and vitreous degeneration. Ultrasound examination was an excellent diagnostic tool, as it was possible to confirm and classify these changes. The piggyback implant reduced the measurements between the ciliary body and the vitreous chamber obtained from the ocular biometry when compared to other usual procedures, with no difference between the axial length and the anterior chamber.

Fidelidade composicional de assembléias de braquiópodes (Rhynconelliformea) na plataforma e talude continental: implicações paleontológicas e geológicas

This paper deals with the Compositional Fidelity of the brachiopods assemblages, dominated by Bouchardia rosea, on the outer shelf and continental slope along São Paulo State. Samples were obtained during the Revizee-Score-Sul-Benthos program. The sampled stations are in sites as depth as 90 to 600 meters, along the outer continental shelf, the shelf break and the top of continental slope. The fidelity estimates were obtained directly from the comparisons between living biota and dead shells, from the same collecting stations. Data come from 66 sampling stations, and the vast majority of the Bouchardia rosea individuals collected (n=2393) were dead (n = 2342, 97.9%). Only 51 individuals were collected alive. When pooling the data from all collecting stations the dead/live frequency is of 2,1% only. The occurrences of Bouchardia rosea shells in siliciclastic bottoms are reduced and living individuals were not found on this type of bottom, at least during the sampling program. These results suggest low compositional fidelity (live-dead) or high compositional mismatch, pointing to a recent decrease in this specie population. The low compositional fidelity of the Bouchardia rosea assemblages in outer shelf sites may be due to changes in seawater temperature, nutrient availability and population history. All these issues must be investigated in the near future

Litofácies e relações estratigráficas da formação Aquidauana no nordeste da Bacia do Paraná - São Sebastião do Paraíso (MG)

The Aquidauana Formation is characterized by sandstones of variable granulation, mudstones and diamectites abundant in clay, typical colors like brick red (vermelho tijolo) of glacial, fluvial and lacustrine origin. It’s chronostratigraphic equivalent to the Itarará group from the Neo Carboniferous age, that under the exploratory view, such units represent important intervals in the basin, occurring together with them minerals as well as energy resources as petroleum, underground water and coal – what requires a great paleogeography and stratigraphy knowledge for its exploration. By gathering information from the columnar sections of the area, it was possible to characterize the sedimentary facies, the stacking pattern as well as the association. It was also made an attempt of stratigraphic correlation, which showed great difficulties since glacial environments present a great lateral discontinuity of the facies besides the complex relationship process of formation. As a result, it was obtained 8 sedimentary facies, the lateral and vertical relations and genesis process. It is proposed that the sedimentary environment in the study area is the fluvio glacial, characterized by alluvial systems formed by defrosted water which transport the sediments that are deposited in plains in front of the glacier (distal outwash). Petrographic thin section analysis showed that the transportation process was ineffective. The grains present punctual to lobular contacts, characterizing good porosity and permeability to the rock, varying these qualities according to more or less existence of matrix. The presence of Iron Oxide deposited between the recrystallization border and feldspathic mineral indicates that this rock has possibly presented a primary rubefaction, intensified by alkaline fluid percolation

Strontium isotopes measurement from bunker cave system: a contribution for the multi-proxy paleoclimate research of Central Europe

In recent years speleothem has been intensely studied due to its great potential of registering paleoclimate proxies but some considerably uncertaintiesregarding speleothem proxy interpretation still exist. In order to minimize these uncertainties, multi-proxy approach has been used. Here is presented the strontium isotope record from Bunker cave, northwest Germany. This cave was previously studied and has proved well record paleoclimate changes during Holocene for central Europe.87Sr/86Sr ratio is presented for rain water, A-horizon soil (water and leachate), C-horizon soil (water and leachate), host rock and host rock leachate, drip water and from a stalagmite (Bu4) previously dated covering the Holocene. Upper soil presented the higher values in contrast with host rock (lower values). Drip water and C-horizon presented intermediated ratios. Sr isotopesare used to track the source of 87Sr/86Sr in the Bunker system, resulting in a mixture between A-horizon soil, C-horizon soil and host rock. A decreasing trend in Bu4 indicates change in the Sr source in the system

Efeitos genéticos tardios de terapias para linfomas

O tratamento dos Linfomas de Hodgkin e Não - Hodgkin é baseado, atualmente, na combinação de drogas antineoplásicas, associadas ou não à radioterapia. Embora as taxas de cura sejam elevadas, sabe-se que tais terapias podem induzir mutações gênicas e cromossômicas que, mais tarde, podem ser responsáveis pela iniciação de novos processos carcinogênicos ou de doenças degenerativas relacionadas a danos genéticos. Sendo assim, o presente estudo teve por objetivo avaliar o efeito toxicogenético tardio (sobre os níveis de danos no DNA) das terapias antineoplásicas para linfomas. Para isso, foram incluídos no estudo 10 pacientes recém diagnosticados com linfoma (Grupo 1- Pré-terapia), 10 pacientes com história de linfoma e que finalizaram o tratamento antineoplásico há no mínimo dois anos (Grupo 2- Pós-terapia) e 10 indivíduos saudáveis (Grupo 3- Controles). Os linfócitos de sangue periférico foram utilizados para se avaliar os níveis de danos no DNA pelo teste do cometa. Além disso, foi avaliada a eficiência do sistema de reparo do DNA frente às lesões induzidas in vitro pelo peróxido de hidrogênio (H2O2). Os dados mostraram que não houve diferença estatisticamente significativa nos níveis de danos no DNA entre os três grupos. No entanto, foram observadas diferenças estatisticamente significativas no reparo das lesões induzidas pelo (H2O2), com o grupo controle apresentado maior indução de danos em comparação com aos demais grupos (p <0,05). Concluindo, os resultados não evidenciaram efeitos toxicogenéticos tardios decorrentes da exposição às terapias antineoplásicas para linfomas

Determinação de fatores angiogênicos e anti-angiogênicos em plasma de gestantes portadoras de pré-eclâmpsia precoce e tardia

Changes in circulating angiogenic factors have been implicated in the pathogenesis of preeclampsia. Thus, evaluation of angiogenesis agonist and antagonist factors is of greater importance to understand the mechanisms responsible for this disorder. The objective of the present study was to evaluate whether circulating angiogenic and anti-angiogenic factors may differentiate early-onset from late-onset preeclampsia. The study was conducted in 86 women with preeclampsia diagnosed in the third trimester of pregnancy. Preeclampsia was classified according to the onset of clinical manifestation in early-onset (before 34 weeks of gestation; n=31) or in late-onset (from 34 weeks of gestation on; n=55) preeclampsia. Serum was obtained from the patients in the moment of the diagnosis and assayed for placental growth factor (PlGF), vascular endothelial growth factor (VEGF), soluble Endoglin (sEng) and soluble form of vascular endothelial growth factor receptor (sVEGFR-1) determination by enzyme-linked immunosorbent assay. The results showed that early-onset preeclampsia was characterized by significant lower levels of PlGF (median 38.3 vs 123.5 pg/mL) and VEGF (median 23.1 vs 35.3 pg/mL) in serum as well as by higher serum levels of sEng (median 54.7 vs 42.1 pg/mL) and sVEGFR-1 (median 5211.0 vs 4657.6 pg/mL) compared with late-onset preeclampsia. In this study serum levels of angiogenic and anti-angiogenic factors prove useful in differentiating early-onset from late-onset preeclampsia in the third trimester of pregnancy. Therefore, these findings suggest that angiogenic factors determination may indicate that early- and late-onset preeclampsia have different pathophysiology
