Crescimento relativo de Aegla castro Schmitt, 1942 (Crustacea, Anomura, Aeglidae)

Os crustáceos anomuros do gênero Aegla Leach (1820) são animais bentônicos característicos das águas continentais da América do Sul. Podem ser encontrados em arroios e rios de correnteza, ocultos sob pedras e detritos vegetais. Foram descritas 61 espécies desse gênero, que se encontram distribuídas pela região Neotropical com limites norte no município de Franca, no Estado de São Paulo, Brasil e sul na Ilha de Madre de Diós, na Província de Última Esperanza, Chile. Esses animais são considerados importantes elos nas cadeias alimentares dos ambientes líminicos, atuando como predadores de larvas aquáticas de insetos e são presas de aves, rãs, jacarés e peixes. Podem também ser utilizados como bioindicadores na avaliação de qualidade das águas onde ocorrem, uma vez que são bastante sensíveis a mudanças do ambiente. Apesar do expressivo número de espécies do gênero Aegla descritas, existem poucos estudos sobre sua dinâmica populacional, especialmente no que diz respeito a análises enfocando crescimento relativo. O objetivo deste trabalho foi caracterizar o crescimento relativo da espécie Aegla castro no município de Itatinga, interior do Estado de São Paulo. Os eglídeos foram coletados mensalmente durante um ano (Mar/07 a Fev/08) no município de Itatinga. Os animais amostrados foram obtidos mediante esforço de coleta e armadilhas. Para o primeiro método, os exemplares foram coletados com puçás ou peneiras posicionados próximos a pedras e seixos, os quais foram removidos manualmente para desalojar os animais que porventura estejam ali abrigados. No segundo método, foram instaladas armadilhas iscadas no final do período da tarde e recolhidas na manhã do dia seguinte. Os exemplares capturados tiveram os sexos determinados com base em caracteres sexuais secundários (posição da abertura do par de gonóporos... (Resumo completo, clicar acesso eletrônico abaixo)

A prática avaliativa em uma instituição privada de ensino de língua estrangeira

The main objective of this work is to describe conceptions and practices of evaluation observed at a private language school. The theoretical background was gathered from Demo (2002a, 2002b), Luckesi (2001), Romão (2001), Shohamy (2001), Hughes (1994) and Depresbiteris (1989). Regarding the data collected, we made use of questionnaires, interviews, group discussions and diaries. Results show that the topics “fear of test” and “test content” were the most frequent ones. Furthermore, there was a harmonious relationship between teacher and students when tests were applied. We observed a “non-verbal agreement” between them, that is, there was a minimum content to be studied and to be asked on a test. We also noticed that classroom activities had a more complex level than the content actually tested.

Saúde e estética: a medicalização da beleza

Este artigo discute os dados levantados em trabalho de campo realizado no Brasil e na Inglaterra, envolvendo a coleta de informações em material de imprensa, dados em arquivos, entrevistas e observação em clínicas estéticas (localizadas em São Paulo e Londres). O artigo toma como problemática central a discussão acerca da cirurgia plástica para fins estéticos como expressão da medicalização da sociedade e da difusão de princípios estruturadores da cultura de consumo. Como desdobramento, desenvolve-se em torno das perguntas: Que impactos a percepção de uma nova forma corporal gera na subjetividade? No caso das mulheres, a cirurgia plástica seria uma prática condicionada pelos ditames dos padrões histórica e culturalmente construídos, que associam a feminilidade a um padrão de beleza socialmente estabelecido, ou poderia ser entendida como uma fonte de poder do indivíduo? Seria, então, um exercício de agência?

Os sentidos da cirurgia estética: utilidade, futilidade, agência e/ou incorporação

This article aims to reflect on the growth of the practice of plastic surgery for cosmetic purposes and its relationship with the contemporary consumer culture. In other words, we discuss how this practice expresses the values and principles for consumer culture and configures itself differently in different contextsin, as the cities of Sao Paulo and London, where he held field work involving the collection of information in press materials, data files, interviews and observation in clinical aes‐ thetic.

Da letargia ao realento: notas sobre o ensino de graduação em administração pública no Brasil no entremeio da crise do Estado e da redemocratização no país (1983-94)

Considering the meantime of Brazilian crisis of State and redemocratization, this article looks for a description and analysis of the facts and circumstances that marked the undergraduate education of Brazilian public administration during this period, considered by the authors as one of the cycles (or stages of construction) of academic education. Methodologically, this article makes a review of academic and non-academic works which deal directly and indirectly the PA themes, including revisiting the sources and analyzing the existing laws and opinions about the undergraduate education in public administration in a continuum of time between 1983-94, through a semi-structured interview with academics who have experienced such period. Regarding the results, this article observes that the period between 1983-94, unlike the first cycle (1952-65) and second cycle (1966-82), when the academic background in public administration had an identity - adherent to the conception (and project) of State and the contours (and production) in the public administration field of knowledge - having the Ebap/FGV a model case, was a problematic stage of construction, reflecting the crisis of State in the 80's years and also the paradigmatic crisis (or discontinuity) in public administration field of knowledge in Brazil during this time.

Conforto térmico em espaços públicos de passagem: estudos em cidades do Estado de São Paulo

This paper presents the results of a study on the thermal comfort in open urban spaces, undertaken in pedestrian streets located in the three towns, Campinas, Baurú, and Presidente Prudente, in the state of Sao Paulo. The study was developed as part of a more extensive project on thermal comfort in different kinds of open public spaces in Brazil. The methodology involved monitoring the microclimatic variables (air and globe temperature, humidity, air velocity and global solar radiation), and structured interviews, in order to assess the actual thermal comfort through the Actual Sensation Vote (ASV) and the personal users’ variables. The Physiological Equivalent Temperature (PET) was also calculated. The results show different limits for neutral temperature in each city: 20-29ºC for Campinas, 21-30 ºC for Bauru and 14-24 ºC for Presidente Prudente). However, 59.5% of the total sample (308 out of 519 individuals) indicated comfort limits ranging from 18 to 26 ºC, which is consistent with the limits proposed by Monteiro and Alucci for the city of Sao Paulo. These results can contribute to evaluate the thermal quality of other public spaces in the same towns.

Rochas calciossilicáticas e feldspáticas na região de Castro Alves e Rafael Jambeiro (BA)

The towns of Castro Alves and Rafael Jambeiro, central-east of Bahia state, are located in the east of São Francisco Craton, in granulite terrains of Salvador-Curaçá Belt, formed in Paleoproterozoic. The region of study contains ortognaisses of Caraíba Complex, metamafic and metaultramafic rocks of São José do Jacuípe Suite, metasedimentary rocks of Tanque Novo-Ipirá Complex, granitoids, pegmatites and alkaline rocks. The study carried out regional and detailed geological mapping in addition to petrographical and geochemical characterization of six areas in the search for targets of feldspar and white diopside, minerals used in ceramic industry. The areas consist of granitic ortognaisses interspersed with lenses of mafic granulite rocks, calc-silicate rock, banded iron formations, paragnaisses, quartzites, and bodies of quartz-feldspar or feldspar pegmatites and alkaline rocks that fill discontinuities. The region of study contains four deformations phases, with a predominance of ductile structures. The foliation Sn has N30E to N70W direction, high angle of dip and is characterized by compositional banding of granoblastic and felsic bands interspersed with nematoblastic or lepidoblastic mafic bands. A mineral or stretching lineation Ln is associated with Sn and has trend of S55E to S72E. The rocks have been suffered a regional metamorphism with granulite facies peak and partial retrogression to greenschist facies. Geochemical studies indicate that the green coloring calc-silicate rocks have lower SiO2, MgO and higher Fe2O3 content compared with white calcssilicate rocks. The alkaline rocks of the studied area have higher Na2O, SiO2 and lower K2O, Fe2O3 content compared with others Paleoproterozoic alkaline rocks of Bahia state. The targets of diopside are associated with white calc-silicate rocks, while the targets of feldspar are associated with paragnaisses, pegmatites and alkaline rocks

Experimental arthritis exacerbates Aggregatibacter actinomycetemcomitans-induced periodontitis in mice

Aim This study aimed to investigate whether chronic antigen-induced arthritis (AIA) influences infection-induced periodontitis (PD) in mice and whether PD modifies the clinical course of AIA. The contribution of anti-TNF-a therapy was also evaluated. Materials and methods The PD was induced in C57BL/6 mice by oral infection with Aggregatibacter actinomycetemcomitans. AIA was induced after infection. Anti-TNF-a and chlorhexidine therapies were used to investigate the role of TNF-a and oral infection on PD and AIA interaction. Maxillae, knee joints, lymph nodes and serum samples were used for histomorphometric, immunoenzymatic and/or real time-PCR analyses. Results Antigen-induced arthritis exacerbated alveolar bone loss triggered by PD infection. In contrast, PD did not influence AIA in the evaluated time-points. PD exacerbation was associated with enhanced production of IFN-? in maxillae and expression of the Th1 transcription factor tBET in submandibular lymph nodes. Increased serum levels of IL-6 and C-reactive protein were also detected. Anti-TNF-a and antiseptic therapies prevented the development and exacerbation of infectious-PD. Anti-TNF-a therapy also resulted in reduced expression of IFN-?, TNF-a and IL-17 in maxillae. Conclusions Altogether, the current results indicate that the exacerbation of infection-induced PD by arthritis is associated with an alteration in lymphocyte polarization pattern and increased systemic immunoreactivity. This process was ameliorated by anti-TNF-a and antiseptic therapies.

On the search for potential anti-Trypanosoma cruzi drugs: Synthesis and biological evaluation of 2-hydroxy-3-methylamino and 1,2,3-triazolic naphthoquinoidal compounds obtained by click chemistry reactions

Five 2-hydroxy-3-substituted-aminomethyl naphthoquinones, nine 1,2,3-triazolic para-naphthoquinones, five nor-beta-lapachone-based 1,2,3-triazoles, and several other naphthoquinonoid compounds were synthesized and evaluated against the infective bloodstream form of Trypanosoma cruzi, the etiological agent of Chagas disease, continuing our screening program for new trypanocidal compounds. Among all the substances, 16-18, 23, 25-29 and 30-33 were herein described for the first time and fifteen substances were identified as more potent than the standard drug benznidazole, with IC50/24 h values in the range of 10.9-101.5 mu M. Compounds 14 and 19 with Selectivity Index of 18.9 and 6.1 are important structures for further studies. (C) 2012 Elsevier Masson SAS. All rights reserved.

BJcuL, a lectin purified from Bothrops jararacussu venom, induces apoptosis in human gastric carcinoma cells accompanied by inhibition of cell adhesion and actin cytoskeleton disassembly

We show that BJcuL, a lectin purified from Bothrops jararacussu venom, exerts cytotoxic effects to gastric carcinoma cells MKN45 and AGS. This effect was due to the direct interaction with specific glycans on the cells surface and was observed by cell viability decrease, disorganization of actin filaments and apoptosis. In addition, BJcuL was able to reduce tumor cell adhesion to matrigel, what was inhibited by specific carbohydrate or partially inhibited when cells were pre-incubated with matrigel. Our results suggest that BJcuL was able to promote apoptosis in both tumor cells lines and therefore has a prospect for potential use in cancer therapy. (C) 2011 Elsevier Ltd. All rights reserved.

Previous exposure to musical auditory stimulation immediately influences the cardiac autonomic responses to the postural change maneuver in women

Background Chronic exposure to musical auditory stimulation has been reported to improve cardiac autonomic regulation. However, it is not clear if music acutely influences it in response to autonomic tests. We evaluated the acute effects of music on heart rate variability (HRV) responses to the postural change maneuver (PCM) in women. Method We evaluated 12 healthy women between 18 and 28 years old and HRV was analyzed in the time (SDNN, RMSSD, NN50 and pNN50) and frequency (LF, HF and LF/HF ratio) domains. In the control protocol, the women remained at seated rest for 10 minutes and quickly stood up within three seconds and remained standing still for 15 minutes. In the music protocol, the women remained at seated rest for 10 minutes, were exposed to music for 10 minutes and quickly stood up within three seconds and remained standing still for 15 minutes. HRV was recorded at the following time: rest, music (music protocol) 0–5, 5–10 and 10–15 min during standing. Results In the control protocol the SDNN, RMSSD and pNN50 indexes were reduced at 10–15 minutes after the volunteers stood up, while the LF (nu) index was increased at the same moment compared to seated rest. In the protocol with music, the indexes were not different from control but the RMSSD, pNN50 and LF (nu) were different from the music period. Conclusion Musical auditory stimulation attenuates the cardiac autonomic responses to the PCM.
