Diagnóstico ambiental do Córrego Bandeirantes, município de Rio Claro, SP: parâmetros biológicos e metais-traço

This study was conducted to verify water quality and environmental impacts related to the occupation of the watershed of the Bandeirantes stream, located in Rio Claro, SP. The intention is to propose measures to enable the mitigation of negative impacts, and boosting the recovery and maintenance of the quality of water resources, preventing its complete degradation. Water analysis were performed at three different points, east, crossing the Ring Road (dirt road) and near the confluence with the Ribeirão Claro. The results indicated significant degradation of water, especially after the crossing, where it witnessed the accumulation of solid waste and easy access to the stream, both for animals as for people, due to limited riparian it. Another impact was observed the current construction of the Forum of Rio Claro in the right side of the stream studied, causing change in the landscape, change the flow properties and removal of existing vegetation at the site of work, defined as an environmentally protected area, as determined by existing law. Measures such as: restoration of riparian zones, effluent treatment, planned urban growth and environmental education of the population, would be essential to mitigate the environmental impacts of watershed Bandeirantes stream

SOCIAL MONOGAMY AND BIPARENTAL CARE OF THE NEOTROPICAL SOUTHERN BAMBOO RAT (KANNABATEOMYS AMBLYONYX)

We analyzed social patterns indicative of the mating system and parental care in a population of the southern bamboo rat (Kannabateomys amblyonyx). This arboreal rodent feeds exclusively on bamboo stems and leaves. We conducted fieldwork from August 2003 to October 2004 in southern Brazil (30 degrees 20`-30 degrees 27`S, 50 degrees 50`-51 degrees 05`W), in patches of introduced Chinese bamboo (Bambusa tuldoides). We captured 18 individuals, 7 of which were adults that received radiotransmitters and were followed from 1 to 12 months. Another 5 animals (adults or subadults) received colored collars. We observed paternal care, delayed juvenile dispersal, and reduced degree of sexual dimorphism, all of which are traits typical of social monogamy. Mated males showed a direct parental behavioral repertoire similar to that of females (with the obvious exception of nursing), including grooming, huddling, and food provisioning. Potential monogamy in this species seems to be a flexible strategy linked to low density of bamboo patches. Females were confined to widely spaced., small home ranges, decreasing the possibility of male defense of and access to > 1 female. The arboreal habits of the species possibly increase the risk of inexperienced young falling from trees or else being depreciated when moving exposed through branches. This risk is probably reduced by the extensive biparental care observed, including the providing of low-energy plant food to young in the nest.

Risk assessment of PM2.5 to child residents in Brazilian Amazon region with biofuel production

Background: Exposure to fine fractions of particulate matter (PM2.5) is associated with increased hospital admissions and mortality for respiratory and cardiovascular disease in children and the elderly. This study aims to estimate the toxicological risk of PM2.5 from biomass burning in children and adolescents between the age of 6 and 14 in Tangara da Serra, a municipality of Subequatorial Brazilian Amazon. Methods: Risk assessment methodology was applied to estimate the risk quotient in two scenarios of exposure according to local seasonality. The potential dose of PM2.5 was estimated using the Monte Carlo simulation, stratifying the population by age, gender, asthma and Body Mass Index (BMI). Results: Male asthmatic children under the age of 8 at normal body rate had the highest risk quotient among the subgroups. The general potential average dose of PM2.5 was 1.95 mu g/kg.day (95% CI: 1.62 - 2.27) during the dry scenario and 0.32 mu g/kg. day (95% CI: 0.29 - 0.34) in the rainy scenario. During the dry season, children and adolescents showed a toxicological risk to PM2.5 of 2.07 mu g/kg. day (95% CI: 1.85 - 2.30). Conclusions: Children and adolescents living in the Subequatorial Brazilian Amazon region were exposed to high levels of PM2.5 resulting in toxicological risk for this multi-pollutant. The toxicological risk quotients of children in this region were comparable or higher to children living in metropolitan regions with PM2.5 air pollution above the recommended limits to human health.

Thymopoiesis and regulatory T cells in healthy children and adolescents

OBJECTIVES: The purpose of this study was to investigate the association between T cell receptor excision circle levels in peripheral blood mononuclear cells and regulatory T cells that co-express CD25 and Foxp3 in healthy children and adolescents of different ages. MATERIALS AND METHODS: The quantification of signal-joint T-cell receptor excision circle levels in the genomic DNA of peripheral blood mononuclear cells was performed using real-time quantitative PCR. The analysis of CD4, CD8, CD25, and Foxp3 expression was performed using flow cytometry. RESULTS: Ninety-five healthy controls (46 females and 49 males) ranging in age from 1 to 18 years were analyzed. The mean T-cell receptor excision circle count in all individuals was 89.095 +/- 36.790 T-cell receptor excision circles per microgram of DNA. There was an inverse correlation between T-cell receptor excision circles counts and age (r = -0.846; p < 0.001) as well as between the proportion of CD4(+)CD25(+)Foxp3(+) T cells and age (r = -0.467; p = 0.04). In addition, we observed a positive correlation between the amount of CD4(+)CD25(+)Foxp3(+) T cells and the amount of T-cell receptor excision circles per microgram of DNA in individuals of all ages (r = -0.529; p = 0.02). CONCLUSIONS: In this study, we observed a decrease in the thymic function with age based on the fact that the level of T-cell receptor excision circles in the peripheral blood positively correlated with the proportion of regulatory T cells in healthy children and adolescents. These findings indicate that although T-cell receptor excision circles and regulatory T cells levels decrease with age, homeostasis of the immune system and relative regulatory T cells population levels are maintained in the peripheral blood.

Self-potential signals from an analog biogeobattery mode

A tank experiment was conducted to check if self-potential (SP) signals can be generated when buried organic matter is wire-connected to a near-surface, oxygen-rich, sediment layer. This experiment demonstrated that once wired, there was a flux of electrons (hence an electric current) between the lower and upper layers of the sandbox with the system responding as a large-scale microbial fuel cell (a type of bioelectrochemical system). An electric current was generated by this process in the wire and the SP method was used to monitor the associated electric potential distribution at the top of the tank.. The electric field was controlled by the flux of electrons through the wire, the oxidation of the organic matter, the reduction of oxygen used as a terminal electron acceptor, and the distribution of the DC resistivity in the tank. The current density through the wire was limited by the availability of oxygen and not by the oxidation of the organic matter. This laboratory experiment incorporated key elements of the biogeobattery observed in some organic-rich contaminant plumes. This analogy includes the generation of SP signals associated with a flux of electrons, the capacity of buried organic matter in sustaining anodic reactions, network resistance connecting terminal redox reactions spatially separated in space, and the existence of anodic secondary coupled reactions. A resistivity tomogram of the tank, after almost a year in operation, suggests that oxidative processes triggered by this geobattery can be imaged with this method to determine the radius of influence of the bioelectrochemical system.

Avaliação do stent coronário eluidor de everolimus XIENCE TM V na cpopulação feminina latino-americana do estudo de braço único SPIRIT Women: acompanhamento clínico de um ano

INTRODUÇÃO: Os estudos com stents farmacológicos têm avaliado predominantemente populações masculinas de descendência europeia. O estudo de braço único SPIRIT Women avalia o stent eluidor de everolimus XIENCE TM V em lesões de novo complexas em uma população feminina do mundo real, incluindo pacientes latino-americanas. Esta análise permite compreender como essa população responde ao implante de stent, comparativamente a pacientes não-latino-americanas. MÉTODOS: Das 1.572 pacientes matriculadas em 73 locais fora dos Estados Unidos, 138 (9%) foram recrutadas na Argentina, no Brasil e na Venezuela. RESULTADOS: As lesões-alvo tinham diâmetro de referência do vaso entre 2,25 mm e 4 mm e extensão da lesão ≤ 28 mm. As características basais foram semelhantes entre os grupos, com exceção de maior prevalência de hipertensão arterial, infarto do miocárdio (IM) de parede anterior e história familiar de doença arterial coronária na coorte latino-americana. As lesões tendiam a ser mais complexas em mulheres latino-americanas, com menor diâmetro de referência do vaso-alvo, maior extensão da lesão, maior excentricidade e angulação e mais lesões tipo B2/C. Os eventos foram adjudicados de acordo com as definições do Academic Research Consortium. Em um ano, o desfecho combinado de morte por todas as causas, IM e revascularização do vaso-alvo (RVA) foi de 12,1% na população não-latino-americana e de 10,1% na população latino-americana (P = 0,58). CONCLUSÕES: Em um ano, os baixos índices de eventos cardíacos adversos, incluindo trombose do stent, falha da lesão-alvo, morte cardíaca, IM e RVA nas mulheres latino-americanas foram comparáveis aos das mulheres não-latino-americanas, apesar da maior complexidade das lesões. Esses resultados demonstram a segurança e a eficácia do stent XIENCE TM V nessa pequena coorte de pacientes latino-americanas, à semelhança do que é observado com populações maiores e mais variadas.

Competitività in sostenibilità urbana e territoriale. L’Emilia Romagna, regione d’Europa

The thesis in Urban and Regional Geography titled “URBAN AND TERRITORIAL COMPETITIVENESS IN SUSTAINABILITY. EMILIA-ROMAGNA, REGION OF EUROPE” is divided into two sections. Section one is additionally composed by two chapters (chap. 1 and 2) and deals with theoretical and gnosiological issues. Section two, of two more chapters (chap. 3 and 4), provides practical contributions: these issues give explanatory patterns to interpret the performances of emiliano-romagnoli urban systems. Chapter one is an introductory chapter. It analyzes globalization that involves a larger and larger number of cities, rich or poor. It also considers the so called “digital divide” either as one of the major phenomena of this unhomogeneous development or as an interesting gnosiological and practical challenge of geography. Globalization is now involving all the cities, large or small, but the small ones have higher risks of exclusion: it depends on their more fragile socio-economic, cultural, and environmental urban structure. That’s why European Union (chapter two) promotes policies and endows politics to sustain cities, because urban systems are the basis for the territorial development. So, European, national and local Institutions are firmly interested in promoting urban and local interventions and projects. Section two deals with economic-geography methods, which consists on collecting indicators and the benchmarking methodology. It also specifically analyzes the urban systems of Emilia-Romagna. Consequences of the globalization on the cities are interpreted with a study of their local resources, intended as potentials for their development. The STeMA approach, proposed by Professor Maria Prezioso (University of Roma, “Tor Vergata”) and used by the ESPON (European Spatial Program Observation Network) project, describes the main “determinants” of the territorial and urban development. These are easily comparable to one another (similar or better performing). This approach achieves two goals. On one hand, it is possible to analyze every urban system in its all main characteristics and to preserve its historical and cultural factors. On another hand, each city is “knowable” and “understandable” by all scholars, as it is objectively comparable. So, urban planners can propose specific “multi-level” and “multi-varied” programs of governance. These will face globalization by exalting local empowerment.
