Razões determinantes de decréscimo do ensino de francês na ultima década, nas escolas da rede oficial do ensino regular de 1. e 2. graus no município do Rio de Janeiro

Este estudo teve como objetivo principal a análise dos elementos que contribuíram e/ou contribuem para o decréscimo do ensino do francês na rede oficial do ensino regular do lº e 2º graus do Município do Rio de Janeiro. Paralelamente, no decorrer do estudo surgiu a oportunidade de avaliar a significação do ensino desta língua como instrumento que possibilita ao educando aperfeiçoar-se e ampliar o seu campo de informação, dando-lhe maiores possibilidades de acompanhar o desenvolvimento cultural , científico e tecnológico do mundo e de fazer um breve histórico da influência francesa na cultura brasileira. o objetivo foi atingido através de uma pesquisa de campo em todo o Município do Rio de Janeiro, junto a diretores das escolas federais, estaduais e municipais do 1º e 2º graus e a professores de francês. Foram utilizados, como instrumentos , dois questionários, A e B (anexo nº I), aplicados a 50% das escolas oficiais do ensino regular do 1º e 2º graus das diversas regiões administrativas do Município do Rio de Janeiro que, na época da pesquisa (outubro de 1977), correspondiam a 232 escolas e a 200 professores lecionando francês . Os resultados obtidos evidenciaram que: 1) o ensino do francês continua sendo ministrado no 1º e 2º Graus do ensino regular; 2) é uma profissão exercida predominantemente por profissionais do sexo feminino (85,5%), procurada por jovens entre 20 e 36 a nos (56,6%), dos quais 41,1% casados; 3) a maioria dos professores tem boa formação profissional, utiliza métodos modernos (como o Capelle, o Vive Voix, o Mauger Rouge, o Frère Jacques e o VIF) e fizeram cursos de pós-graduação (68%); 4) apenas 23,5% dos professores conseguiram bolsas de estudos ; 5) os professores com mais de 8 anos (64 ,4% ) , e com 2 a 4 anos (24,4%) de magistério parecem os mais interessados pelo ensino do francês ; 6) 23,5% dos professores observaram pelas escolas, e 48,9% parte dos alunos; 7) a uma diminuição na oferta desta disciplina observaram a diminuição na procura por IV e a XVIII Regiões Administrativas são as que contam com maior número de professores de francês; B) em 1965 no 1º grau, 270 alunos optaram por esta língua e 170 pelo inglês; em 1968 as opções pelo ensino do francês no 1º grau aumentaram para 633 chegando a 8.465 em 1977; 9) 1970 foi apontado como o ano do começo do decréscimo (0,5%), que aumentou em 1975(6,8%), sofrendo novamente uma queda em 1977 (3,6%); 10) o ensino do francês é oferecido em 61,2% das escolas, e 37,6% que não o fazem; 11) a partir das 7as, e 8as, séries o número de alunos diminui tanto para o francês como para o inglês; 12) as principais razoes apontadas pelas escolas e pelos professores como causas do decréscimo do ensino do francês no Município do Rio de Janeiro, por ordem de importância, são: a diminuição da oferta pelas escolas, a falta de professores, a falta de interesse dos alunos, a preocupação com a formação profissional, a influência norte-americana, além de métodos inadequados, programas mal elaborados, a do ensino (Leis 4024/61 e 5692/71) e a pouca divulgação francesa.

A negative screen for mutations in calstabin 1 and 2 genes in patients with dilated cardiomyopathy

Background Calstabins 1 and 2 bind to Ryanodine receptors regulating muscle excitation-contraction coupling. Mutations in Ryanodine receptors affecting their interaction with calstabins lead to different cardiac pathologies. Animal studies suggest the involvement of calstabins with dilated cardiomyopathy. Results We tested the hypothesis that calstabins mutations may cause dilated cardiomyopathy in humans screening 186 patients with idiopathic dilated cardiomyopathy for genetic alterations in calstabins 1 and 2 genes (FKBP12 and FKBP12.6). No missense variant was found. Five no-coding variations were found but not related to the disease. Conclusions These data corroborate other studies suggesting that mutations in FKBP12 and FKBP12.6 genes are not commonly related to cardiac diseases.

Identifying common and specific microRNAs expressed in peripheral blood mononuclear cell of type 1, type 2, and gestational diabetes mellitus patients

Abstract Background Regardless the regulatory function of microRNAs (miRNA), their differential expression pattern has been used to define miRNA signatures and to disclose disease biomarkers. To address the question of whether patients presenting the different types of diabetes mellitus could be distinguished on the basis of their miRNA and mRNA expression profiling, we obtained peripheral blood mononuclear cell (PBMC) RNAs from 7 type 1 (T1D), 7 type 2 (T2D), and 6 gestational diabetes (GDM) patients, which were hybridized to Agilent miRNA and mRNA microarrays. Data quantification and quality control were obtained using the Feature Extraction software, and data distribution was normalized using quantile function implemented in the Aroma light package. Differentially expressed miRNAs/mRNAs were identified using Rank products, comparing T1DxGDM, T2DxGDM and T1DxT2D. Hierarchical clustering was performed using the average linkage criterion with Pearson uncentered distance as metrics. Results The use of the same microarrays platform permitted the identification of sets of shared or specific miRNAs/mRNA interaction for each type of diabetes. Nine miRNAs (hsa-miR-126, hsa-miR-1307, hsa-miR-142-3p, hsa-miR-142-5p, hsa-miR-144, hsa-miR-199a-5p, hsa-miR-27a, hsa-miR-29b, and hsa-miR-342-3p) were shared among T1D, T2D and GDM, and additional specific miRNAs were identified for T1D (20 miRNAs), T2D (14) and GDM (19) patients. ROC curves allowed the identification of specific and relevant (greater AUC values) miRNAs for each type of diabetes, including: i) hsa-miR-1274a, hsa-miR-1274b and hsa-let-7f for T1D; ii) hsa-miR-222, hsa-miR-30e and hsa-miR-140-3p for T2D, and iii) hsa-miR-181a and hsa-miR-1268 for GDM. Many of these miRNAs targeted mRNAs associated with diabetes pathogenesis. Conclusions These results indicate that PBMC can be used as reporter cells to characterize the miRNA expression profiling disclosed by the different diabetes mellitus manifestations. Shared miRNAs may characterize diabetes as a metabolic and inflammatory disorder, whereas specific miRNAs may represent biological markers for each type of diabetes, deserving further attention.

Papel del factor de transcripción ETS 1 y 2 sobre la liberación y funcionalidad de las células progenitoras endoteliales en arterias humanas. Modulación por fármacos

La enfermedad cardiovascular sigue siendo la principal causa de morbilidad y mortalidad a nivel mundial en países desarrollados, fundamentalmente en pacientes con DM tipo 2, en algunas poblaciones puede representar el 50% o más de las muertes por diabetes (Joseph and Golden, 2014). Esto se debe en gran medida a factores ya conocidos como la predisposición genética, la aterogénesis acelerada, la inflamación crónica, la isquemia silente y la presencia de patologías co-existentes como la hipertensión o la dislipidemia. La diabetes es sin duda alguna, uno de los problemas de salud más graves del siglo XXI y actualmente en España, la prevalencia nacional es de 10,83% (FDI 2013). Las células progenitoras endoteliales juegan un papel clave en los procesos de reparación endotelial. En los pacientes con DM tipo 2 y enfermedad cardiovascular, se sabe que la funcionalidad de las EPCs es deficiente, aunque el mecanismo exacto de disfunción aún es incierto. Además, está bien descrito que en la evolución natural de los pacientes con DM tipo 2 presentan un mayor número de complicaciones y con mayor frecuencia estos pacientes estarán abocados a procedimientos de revascularización. Múltiples estudios (Sidhu and Boden, 2015; Verma et al., 2013) que han señalado la importancia de una adecuada terapia de reparación endotelial (terapia con EPCs), que ayudaría a disminuir las alteraciones en los procesos de reendotelización en los pacientes con DM tipo 2 y enfermedad cardiovascular, y por consiguiente disminuiría la aparición de la enfermedad cardiovascular (ECV)...
