O PIBID - Programa Institucional de Bolsas de Iniciação à Docência e a crise das Licenciaturas: o caso de um Curso de Pedagogia a Distância

Tendo em vista a atual crise das licenciaturas, especialmente em termos da pouca atratividade que a formação para a docência vem apresentando em nosso contexto educacional e, considerando, ainda, as críticas sobre a fragilidade da formação inicial de professores ocorrer na modalidade a distância (no caso, o curso de Pedagogia), o PIBID - Programa Institucional de Bolsas de Iniciação à Docência surge como uma política de incentivo e valorização do magistério com o propósito de contribuir para uma formação mais sólida e articulada em termos da relação teoria-prática, especialmente pela proximidade que favorece aos alunos bolsistas, com o cotidiano escolar – este é o foco desta investigação que teve por objetivos: refletir sobre o histórico da formação docente em interface com a desvalorização do magistério que, consequentemente, levou à crise das licenciaturas e, a partir disso, analisar a proposição do PIBID como uma política pública para o enfrentamento desta crise; analisar as representações de bolsistas do PIBID, de um curso de Pedagogia a distância, sobre a experiência que estão tendo, e se ela contribui, no caso dos licenciandos, para o fortalecimento da escolha pela carreira docente; verificar as contribuições do programa para a formação dos licenciandos, dos supervisores (professores das escolas públicas parceiras) e do coordenador de área e se este oportuniza uma complementação na preparação para o exercício da docência. A pesquisa realizou uma revisão da literatura sobre a crise das licenciaturas e o contexto do aparecimento do PIBID, bem como sobre a formação de professores ocorrer na modalidade a distância, tendo como referencial teórico autores como Libâneo (1998), Gatti e Barreto (2009), Bahia e Duran (2011), Scheibe (2006), Sommer (2010), FCC (2009), Tardif (2005). Realizou, também, uma pesquisa de campo que teve como sujeitos sete bolsistas do PIBID de um curso de Pedagogia a distância (de uma instituição de ensino superior, particular, de São Paulo), sendo: quatro licenciandas, duas supervisoras e uma coordenadora de área do subprojeto. Foram aplicados dois instrumentos para a coleta de dados: um questionário para o delineamento do perfil dos sujeitos e a realização de entrevistas de aprofundamento. As reflexões realizadas a partir da revisão da literatura e das análises dos dados coletados junto aos sujeitos indicam que: em relação à proposição da formação inicial de professores a distância, esta denota maiores críticas, diferentemente da formação continuada de professores a distância, que apresenta uma maior aceitabilidade; em relação ao PIBID, os estudos vêm apontando a positividade das diversas experiências que vêm se desenvolvendo no território nacional e que denotam um trabalho articulado entre teoria e prática, bem como no resgate da identidade docente, com uma ênfase na valorização, inserção e permanência dos licenciandos nos seus cursos; as representações dos sujeitos investigados sobre a experiência que estão tendo com o PIBID apontam para: o reconhecimento de que o Programa garante, efetivamente, a reflexão e vivência entre a teoria e prática; a contribuição para a aquisição de maior segurança na relação com os alunos das escolas parceiras e também no desenvolvimento das atividades práticas; a certeza e/ou convicção de que realmente querem ser professoras.

Serviços de Ação Social da Universidade de Coimbra: a política de atribuição de bolsas de estudo e o Serviço Social

Este trabalho analisa as políticas de ação social escolar no ensino superior público a partir da década de 60, nomeadamente na atribuição de bolsas de estudo a estudantes da Universidade de Coimbra. Analisa ainda as alterações que estas políticas têm vindo a sofrer ao longo dos anos e a sua relação com o direito ao ensino e igualdade de oportunidades de acesso e êxito escolar consagrado na Constituição Portuguesa. O Serviço Social tem uma intervenção relevante nos Serviços de Ação Social da Universidade de Coimbra, em várias áreas, praticamente desde a sua criação. Neste trabalho, a análise das práticas do Serviço Social centra-se na atribuição de bolsas de estudo, nos últimos 10 anos. Trata-se de um estudo exploratório realizado com base em pesquisa bibliográfica e documental. Outra fonte de recolha de informação foi a entrevista, realizada à Assistente Social, e Responsável pelo Serviço de Bolsas entre 1978 e 2012, Dra. Elisa Decq Motta. As alterações às políticas de ação social no que se refere à atribuição de bolsas de estudo, relacionadas com o cálculo dos rendimentos ou com as condições de elegibilidade, têm vindo a pôr em causa o direito à igualdade de oportunidades dos estudantes, no acesso e na permanência no ensino superior. Muitos deles, economicamente carenciados, estão a ficar de fora do sistema de ação social no ensino superior em virtude destas alterações. É preocupação dos Serviços de Ação Social da Universidade de Coimbra a regressão a que se tem vindo a assistir, e as suas consequências para os estudantes do ensino superior, pelo que é urgente inverter este caminho. / This study analyses the academic social policies in the high-level educational institutions since the 60’s, namely in the allocation of scholarships to students from the University of Coimbra. Furthermore, the changes that such policies have been suffering over the last years, and their relationship with the right to education and equal opportunities to the access and scholar success that every citizen has, as stated by the Portuguese Constitution, are also examined. Since its establishment, the Social Service is a relevant area of the Social Services of the University of Coimbra, in several areas. The analyses present in this study will focus on the last 10 years, specifically on the scholarships allocation. This study is based on literature and documents research, as well as on an interview to the Social Worker responsible for the Scholarships Service from 1978 to 2012, Dra. Elisa Decq Motta. The social policies changes related with the scholarships assignment, especially those associated with the income assessment and eligibility conditions are serious hindrances to the right of equal admission opportunity and maintenance in higher education that all students have. Due to these changes, several students with financial issues are not supported by the social service in higher education. The observed changes, and its consequences for students are a matter of concern for the Social Services of University of Coimbra. It is imperative to revert the current situation.

Complicações imediatas e tardias após cirurgia de reservatório ileal na polipose adenomatosa familiar

BACKGROUND: Restorative proctocolectomy is the procedure of choice to treat familial adenomatous polyposis, however it can be associated to short-term and long-term postoperative complications. AIM: To evaluate the occurrence of complications related to the surgical treatment of familial adenomatous polyposis with ileal pouch technique. METHODS: Retrospective study of 69 patients with familial adenomatous polyposis after rectocolectomy with ileal reservoir between 1984 and 2006, operated on Coloproctology Group, Medical Sciences Faculty, State University of Campinas, Campinas, SP, Brazil. The median follow-up period was 82 (2-280) months. Data obtained were surgical techniques and postoperative complications. RESULTS: The morbidity and mortality were 63.8% and 2.9%, respectively. The most frequent complications were small-bowel obstruction (17.4%), anastomotic stricture (15.9%) and pelvic sepsis (10.1%). Acute ischemia of the ileal pouch (4.3%), pouchitis (2.9%) and ileal pouch-related fistula (2.9%) had poorer frequency than others. CONCLUSIONS: The morbid-mortality was similar to the literature?s data and it is acceptable for a complex surgery in two terms like the ileal reservoir-anal anastomosis. The small-bowel obstruction was the most frequent complication. However, ischemia of the reservoir, pouchitis and pelvic sepsis were important complications and was related to the failure of the ileal reservoir.

Resultados da cirurgia de reservatórios ileais em pacientes com doença de Crohn

BACKGROUND: Total rectocolectomy and ileal pouch-anal anastomosis is the choice surgical procedure for patients with ulcerative colitis. In cases of Crohn's disease post-operative diagnosis, it can be followed by pouch failure. AIM: To evaluate ileal pouch-anal anastomosis long-term outcome in patients with Crohn's disease. METHODS: Between February 1983 and March 2007, 151 patients were submitted to ileal pouch-anal anastomosis by Campinas State University Colorectal Unit, Campinas, SP, Brazil, 76 had pre-operative ulcerative colitis diagnosis and 11 had post-operative Crohn's disease diagnosis. Crohn's disease diagnosis was made by histopathological biopsies in nine cases, being one in surgical specimen, two cases in rectal stump, small bowel in two cases, ileal pouch in three and in perianal abscess in one of them. The median age was 30.6 years and eight (72.7%) were female. RESULTS: All patients had previous ulcerative colitis diagnosis and in five cases emergency colectomy was done by toxic megacolon. The mean time until of Crohn's disease diagnosis was 30.6 (6-80) months after ileal pouch-anal anastomosis. Ileostomy closure was possible in 10 cases except in one that had ileal pouch fistula, perianal disease and small bowel involvement. In the long-term follow-up, three patients had perineal fistulas and one had also a pouch-vaginal fistula. All of them were submitted to a new ileostomy and one had the pouch excised. Another patient presented pouch-vaginal fistula which was successfully treated by mucosal flap. Three patients had small bowel involvement and three others, pouch involvement. All improved with medical treatment. Presently, the mean follow-up is 76.5 months and all patients are in clinical remission, and four have fecal diversion. The remaining patients have good functional results with 6-10 bowel movements/day. CONCLUSION: Crohn's disease diagnosis after ileal pouch-anal anastomosis for ulcerative colitis may be usual and later complications such fistulas and stenosis are common. However, when left in situ ileal pouch is associated with good function.

Desmoid tumor in patients with familial adenomatous polyposis

CONTEXT: Desmoid tumors constitute one of the most important extraintestinal manifestations of familial adenomatous polyposis. The development of desmoids is responsible for increasing morbidity and mortality rates in cases of familial adenomatous polyposis. OBJECTIVES: To evaluate the occurrence of desmoid tumors in familial adenomatous polyposis cases following prophylactic colectomy and to present patient outcome. METHODS: Between 1984 and 2008, 68 patients underwent colectomy for familial adenomatous polyposis at the School of Medical Sciences Teaching Hospital, University of Campinas, SP, Brazil. Desmoid tumors were found in nine (13.2%) of these patients, who were studied retrospectively by consulting their medical charts with respect to clinical and surgical data. RESULTS: Of nine patients, seven (77.8%) were submitted to laparotomy for tumor resection. Median age at the time of surgery was 33.9 years (range 22-51 years). Desmoid tumors were found in the abdominal wall in 3/9 cases (33.3%) and in an intra-abdominal site in the remaining six cases (66.7%). Median time elapsed between ileal pouch-anal anastomosis and diagnosis of desmoid tumor was 37.5 months (range 14-60 months), while the median time between colectomy with ileorectal anastomosis and diagnosis was 63.7 months (range 25-116 months). In 6/9 (66.7%) patients with desmoid tumors, the disease was either under control or there was no evidence of tumor recurrence at a follow-up visit made a mean of 63.1 months later (range 12-240 months). CONCLUSIONS: Desmoid tumors were found in 13.2% of cases of familial adenomatous polyposis following colectomy; therefore, familial adenomatous polyposis patients should be followed-up and surveillance should include abdominal examination to detect signs and symptoms. Treatment options include surgery and clinical management with antiestrogens, antiinflammatory drugs or chemotherapy.

Short-Term effect of COX-2 selective inhibitor as an adjunct for the treatment of periodontal disease: a clinical double-blind study in humans

Adjunctive therapeutic strategies that modulate the inflammatory mediators can play a significant role in periodontal therapy. In this double-blind, placebo-controlled study, 60 subjects diagnosed as periodontitis patients were evaluated for 28 days after periodontal treatment combined with selective cyclooxygenase-2 (COX-2) inhibitor. The experimental group received scaling and root planning (SRP) combined with the Loxoprofen antiinflammatory drug (SRP+Loxoprofen). The control group received SRP combined with placebo (SRP+placebo). Plaque index (PI), probing pocket depth (PD) and bleeding on probing (BOP) were monitored with an electronic probe at baseline and after 14 and 28 days. Both groups displayed clinical improvement in PD, PI and BOP. They also showed statistically similar values (p>0.05) of PD reduction on day 14 (0.4 mm) and on day 28 (0.6 mm). At the baseline, few deeper sites (>7 mm) from SRP+Loxoprofen group were responsible and most PD reduction was observed after 14 days (p<0.05). The percentage of remaining deep pockets (>7 mm) after 14 days in the SRP+Loxoprofen group was significantly lower (p<0.05) than in the SRP+placebo group. Loxoprofen presents potential effect as an adjunct of periodontal disease treatment, but long-term clinical trials are necessary to confirm its efficacy.

Evaluation of capillaries with different inner coatings for DNA analysis using dilute polymer solutions by capillary electrophoresis

In this work three capillary columns, one with uncoated inner wall and two with covalently-bound internal coatings - poly(vinyl alcohol) (PVA) and poly(dimethylacrylamide) (PDMA) - both covalently covered - were used to separate DNA fragments and compared to DNA separation using replaceable polymer solutions. The separations were performed using hydroxyethylcellulose (HEC) (90-105 kDa) in concentrations ranging from 0.00 to 2.00% m/v. The results indicated that the separation efficiency was higher in the PVA capillary than in the PDMA in all evaluated concentrations of HEC. In addition, higher resolution was also observed in PVA-coated capillary since in PDMA the shape of the peaks was not reproducible when subsequent runs were performed. Contrary to what has previously been reported in the literature, no reasonable separation was possible in bare fused silica.

Estudo clínico da aplicação de matriz inorgânica de osso associado a peptídeo sintético de adesão celular (MIO/P-15), PepGen P-15®, em lesões periodontais avançadas de cães

Os mecanismos biológicos desenvolvidos para aumentar a qualidade da regeneração óssea e da reparação tecidual de sítios periodontais específicos continuam a ser um desafio e têm sido complementado pela capacidade de adesão celular do colágeno do tipo I, promovida por um peptídeo sintético de adesão celular (P-15), associado a uma matriz inorgânica de osso (MIO) para formar MIO/P-15. O objetivo deste estudo foi avaliar a perda do nível clínico de inserção e a resposta da bolsa periodontal em dentes após 3 e 6 meses da aplicação de enxerto com MIO/P-15. Vinte e um cães do Hospital Veterinário da Universidade de São Paulo foram anestesiados para realização de tratamento periodontal e 132 faces dentais com perda de nível clínico de inserção foram tratadas, sendo que 36,4% (48 faces) receberam o peptídeo de adesão celular e 63,6% (84 faces) compuseram o grupo controle que recebeu tratamento convencional (retalho muco-gengival e aplainamento radicular). O procedimento foi documentado através de radiografia intra-oral e todas as sondagens de bolsas periodontais foram fotografadas. Depois de 3 e de 6 meses, os animais foram re-anestesiados a fim de se obter novas avaliações, radiografias, fotografias e sondagens periodontais. As 48 faces com perda de nível clínico de inserção que receberam material de enxertia apresentaram taxa de 40% de recuperação do nível clínico de inserção após 6 meses. O grupo controle de faces dentais não apresentou alteração do nível clínico de inserção. A face palatina foi a que apresentou melhor taxa de regeneração (40%) e os dentes caninos e molares mostraram as melhores respostas (57,14% e 65%, respectivamente). Não houve sinais de infecção pós-cirúrgica relacionadas à falta de higienização oral dos animais. Pode-se concluir que o MIO/P-15 auxilia na regeneração e re-aderência das estruturas periodontais, incluindo osso alveolar. Sua aplicação mostrou-se fácil e prática e a incidência de complicações pós-cirúrgicas foi baixa. Ainda assim, mais estudos e pesquisas são necessários para que se avalie a quantidade e a qualidade do osso e do ligamento periodontal formados.

Novel Primate-Specific Genes, RMEL 1, 2 and 3, with Highly Restricted Expression in Melanoma, Assessed by New Data Mining Tool

Melanoma is a highly aggressive and therapy resistant tumor for which the identification of specific markers and therapeutic targets is highly desirable. We describe here the development and use of a bioinformatic pipeline tool, made publicly available under the name of EST2TSE, for the in silico detection of candidate genes with tissue-specific expression. Using this tool we mined the human EST (Expressed Sequence Tag) database for sequences derived exclusively from melanoma. We found 29 UniGene clusters of multiple ESTs with the potential to predict novel genes with melanoma-specific expression. Using a diverse panel of human tissues and cell lines, we validated the expression of a subset of three previously uncharacterized genes (clusters Hs.295012, Hs.518391, and Hs.559350) to be highly restricted to melanoma/melanocytes and named them RMEL1, 2 and 3, respectively. Expression analysis in nevi, primary melanomas, and metastatic melanomas revealed RMEL1 as a novel melanocytic lineage-specific gene up-regulated during melanoma development. RMEL2 expression was restricted to melanoma tissues and glioblastoma. RMEL3 showed strong up-regulation in nevi and was lost in metastatic tumors. Interestingly, we found correlations of RMEL2 and RMEL3 expression with improved patient outcome, suggesting tumor and/or metastasis suppressor functions for these genes. The three genes are composed of multiple exons and map to 2q12.2, 1q25.3, and 5q11.2, respectively. They are well conserved throughout primates, but not other genomes, and were predicted as having no coding potential, although primate-conserved and human-specific short ORFs could be found. Hairpin RNA secondary structures were also predicted. Concluding, this work offers new melanoma-specific genes for future validation as prognostic markers or as targets for the development of therapeutic strategies to treat melanoma.

Anti-inflammatory and antinociceptive effects of Baccharis dracunculifolia DC (Asteraceae) in different experimental models

Aim of the study: The aerial parts of Baccharis dracunculifolia D.C., popularly known as ""alecrim do campo"" are used in folk medicine as anti-inflammatory. The aim of the present study was to evaluate the anti-inflammatory and antinociceptive activities of the crude hydroalcoholic extract obtained from leaves of Baccharis dracunculifolia (BdE), which have not been reported. Matetials and methods: BdE was analyzed by HPLC and in vivo evaluated (doses ranging from 50 to 400 mg/kg, p.o.) by using the acetic acid-induced abdominal constrictions, paw oedema induced by carrageenan or histamine, overt nociception models using capsaicin, glutamate or phorbol myristate acetate (PMA), formalin-induced nociception and mechanical hypernociception induced by carrageenan or complete Freund adjuvant (CFA). As positive controls it was used paracetamol in both acetic acid and formalin tests; dipyrone in capsaicin, glutamate and PMA-induced nociception; indomethacin in CFA and carrageenan-induced hypernociception models. In addition, the in vitro effects of BdE on COX-2 activity and on the activation of NF-kappa B were also evaluated. Results: BdE (50-400 mg/kg, p.o.) significantly diminished the abdominal constrictions induced by acetic acid, glutamate and CFA. Furthermore, BdE also inhibited the nociceptive responses in both phases of formalin-induced nociception. BdE, administered orally, also produced a long-lasting anti-hypernociceptive effect in the acute model of inflammatory pain induced by carrageenan. It was also observed the inhibition of COX-2 activity by BdE. Conclusion: In summary, the data reported in this work confirmed the traditional anti-inflammatory indications of Baccharis dracunculifolia leaves and provided biological evidences that Baccharis dracunculifolia, like Brazilian green propolis, possess antinociceptive and anti-inflammatory activities.

Serotonergic neurotransmission in the dorsal raphe nucleus recruits in situ 5-HT2A/2C receptors to modulate the post-ictal antinociception

The post-ictal immobility syndrome is followed by a significant increase in the nociceptive thresholds in animals and humans. The aim of this study was to assess the involvement of the dorsal raphe nucleus (DRN) in the post-ictal antinociception. The second aim was to study the role of serotonergic intrinsic mechanisms of the DRN in this hypo-algesic phenomenon. Pentylenetetrazole (PTZ), an ionophore GABA-mediated Cl- influx antagonist, was peripherally used to induce tonic-clonic seizures in Wistar rats. The nociceptive threshold was measured by the tail-flick test. Neurochemical lesions of the DRN, performed with microinjection of ibotenic acid (1.0 mu g/0.2 mu L), caused a significant decrease of tonic-clonic seizure-induced antinociception, suggesting the involvement of this nucleus in this antinociceptive Process. Microinjections of methysergide (1.0 and 5.0 mu g/0.2 mu L), a non-selective serotonergic receptor antagonist, into DRN caused a significant decrease in the post-ictal antinociception in seizing animals, compared to controls, in all post-ictal periods Presently studied. These findings were corroborated by microinjections of ketanserin (at 1.0 and 5.0 mu g/0.2 mu L) into DRN. Ketanserin is an antagonist with large affinity for 5-HT2A/2C serotonergic receptors, which, in this Case, Caused a significant decrease in the tail-flick latencies in seizing animals, compared to controls after the first 20 min following tonic-clonic convulsive reactions. These results indicate that serotonergic neurotransmission of the DRN neuronal clusters is involved in the organization of the post-ictal hypo-algesia. The 5-HT2A/2C receptors of DRN neurons seem to be critically involved in the increase of nociceptive thresholds following tonic-clonic seizures. (c) 2008 Elsevier Inc, All rights reserved.

Enamel Wetness Effects on Bond Strength Using Different Adhesive Systems

Objective: To evaluate, through the application of different dentin bonding systems, the influence of wetness on shear bond strength in enamel. Methods: This study evaluated three etch-and-rinse adhesive systems (Scotchbond MP [used with and without primer]; Singlebond; and Prime&Bond 2.1) and two self-etching adhesive systems (Clearfil SE Bond; and Xeno IV). Flat bovine enamel surfaces were either air-dried for 30 seconds or blotted with absorbent paper after acid-etching for the conventional bonding agents or before the application of self-etching bonding agents. The resin composite EsthetX was bonded to flat surfaces that had been treated with one of the adhesives, following the manufacturer`s instructions. After being stored in water at 37 degrees C for one week, bonded specimens were broken in shear. Data were evaluated with two-way analysis of variance (ANOVA) and Student-Newman-Keuls tests (alpha=0.05). For comparing each condition individually, regardless of the adhesive or wetness condition, a one-way ANOVA and a Student-Newman-Keuls test (alpha=0.05) were applied. Results: The two-way ANOVA showed significant differences among adhesive systems. An interaction effect was also observed (p < 0.05), but wetness did not influence shear bond strength (p=0.98). The one-way ANOVA showed that the all-in-one adhesive was the only material influenced by the presence of water at the enamel`s surface. Conclusion: The all-in-one adhesive behaved differently depending on whether the enamel surface was dry or wet.

Controle dos estoques p??blicos de gr??os

O Sistema de Controle Interno do Poder Executivo sofreu recente reformula????o que culminou na cria????o da Secretaria Federal de Controle (SFC), ??rg??o respons??vel pela avalia????o da gest??o p??blica e acompanhamento dos programas de governo. A Secretaria de Controle Interno (Ciset) no Minist??rio da Agricultura, unidade seccional da SFC, desenvolveu trabalho na ??rea de estoques governamentais de gr??os, geridos pela Companhia Nacional de Abastecimento (Conab), afetos ao Programa de Garantia de Pre??os M??nimos (PGPM). Para operacionalizar o PGPM, o governo adquire estoques de gr??os no per??odo da safra, quando os pre??os est??o rebaixados pelo excesso de oferta e administra esses estoques at?? o per??odo de entressafra, quando os mesmos retornam ao mercado consumidor, por meio de leil??es de venda. Foram cobradas in??meras d??vidas atrasadas de empresas armazenadoras, com o retorno de recursos aos cofres p??blicos, aliviando, assim, a carga de processos em cobran??a administrativa e judicial. Foi cobrado o ressarcimento de preju??zos causados por desvio, perda e sinistro de estoques, bem como foi determinada a cobran??a de preju??zos por desvios perda e sinistro que se encontravam pendentes de solu????o. Desenvolveu-se a????o preventiva, evitando preju??zos relativos a safras antigas mal armazenadas e com riscos de perda de qualidade. Procedeu-se ?? redu????o do quantitativo de estoques p??blicos de safras antigas, reduzindo-se os riscos de deprecia????es e perdas. Realizou-se o saneamento de inconsist??ncias e falhas no sistema de controle do cadastro de armaz??ns e dos contratos de dep??sito de estoques p??blicos por empresas armazenadoras privadas. Iniciou-se efetivamente a aferi????o da qualidade dos estoques p??blicos, de acordo com a classifica????o oficial do Maara, quando das opera????es de aquisi????es indiretas (transforma????o de estoques de empr??stimos do governo federal ??? EFG ??? em Aquisi????es do Governo Federal ??? AFG) e das vendas em leil??es p??blicos (via bolsas de mercadorias). O sucesso da iniciativa levou ?? cria????o de um grupo de trabalho interministerial envolvendo os Minist??rios da Fazenda e da Agricultura, destinados a analisar e a oferecer alternativas de solu????o para os problemas operacionais do PGPM
