Cidadania e participa??o política na época da Independência do Brasil
Neves, Lúcia Maria Bastos P.;
Cadernos CEDES , 2002, DOI: 10.1590/S0101-32622002000300004
Abstract: relying on periodicals and political tracts as its main sources, this paper intends to analyze the period of brazilian independence as an endeavor to establish new ideas and political practices regarding the relationship between individuals and both society and the state. however, this drive toward an authentically public political sphere was cut short by circumstances, which hindered the constitution of a true notion of citizenship. if citizenship and political participation do take a long time to mature in a really public political sphere, this time is even longer in such countries as brazil, ridden almost from the start by the exclusion brought about by large landholdings and slavery.
Cidadania e participa o política na época da Independência do Brasil
Neves Lúcia Maria Bastos P.
Cadernos CEDES , 2002,
Abstract: O presente artigo pretende analisar a conjuntura da Independência do Brasil enquanto uma tentativa de implantar novas idéias e práticas políticas quanto ao relacionamento do indivíduo e da sociedade com o Estado, tendo como fontes principais os escritos de circunstancia, ou seja, os periódicos e os panfletos políticos. Nesse sentido, tais novidades poderiam ter resultado na constitui o de uma autêntica esfera pública de poder, mas acabaram limitadas e reorientadas em fun o das circunstancias da época, impedindo que se criasse uma verdadeira no o de cidadania no país. Verifica-se, portanto, que cidadania e participa o política em uma esfera verdadeiramente pública de poder s o processos de constru o lenta, ainda mais em países como o Brasil, envolvido desde seus inícios pela exclus o que a grande propriedade e a escravid o asseguraram.

Abstract: The effect of pH on the glucose metabolism of non-growing cells of L. lactis MG1363 was studied by in vivo NMR in the range 4.8 to 6.5. Immediate pH effects on glucose transporters and/or enzyme activities were distinguished from transcriptional/translational effects by using cells grown at the optimal pH of 6.5 or pre-adjusted to low pH by growth at 5.1. In cells grown at pH 5.1, glucose metabolism proceeds at a rate 35% higher than in non-adjusted cells at the same pH. Besides the upregulation of stress-related genes (such as dnaK and groEL), cells adjusted to low pH overexpressed H+-ATPase subunits as well as glycolytic genes. At sub-optimal pHs, the total intracellular pool of lactic acid reached approximately 500 mM in cells grown at optimal pH and about 700 mM in cells grown at pH 5.1. These high levels, together with good pH homeostasis (internal pH always above 6), imply intracellular accumulation of the ionized form of lactic acid (lactate anion), and the concomitant export of the equivalent protons. The average number, n, of protons exported with each lactate anion was determined directly from the kinetics of accumulation of intra- and extracellular lactic acid as monitored online by 13C-NMR. In cells non-adjusted to low pH, n varies between 2 and 1 during glucose consumption, suggesting an inhibitory effect of intracellular lactate on proton export. We confirmed that extracellular lactate did not affect the lactate: proton stoichiometry. In adjusted cells, n was lower and varied less, indicating a different mix of lactic acid exporters less affected by the high level of intracellular lactate. A qualitative model for pH effects and acid stress adaptation is proposed on the basis of these results.

Abstract: background: motor assessments are frequently applied by physical therapists. the motor assessment scale (mas) evaluates motor function and has been shown to be a reliable and valid instrument for stroke patients. however, no previous study has examined its reliability in brazil. objectives: the aim of this study was to determine the inter- and intra-rater reliability of the portuguese version of the mas in chronic stroke patients and to observe its comprehension and acceptability by brazilian physical therapists without prior training on its use. methods: for inter-rater analysis, 23 physical therapists scored the functional ability of six video-recorded stroke patients during assessment with the portuguese version of the mas; intra-rater reliability was determined by the assessment of 15 video-recorded stroke patients by seven physical therapists, on two separate occasions, three weeks apart. at the end of the study, the physical therapists answered a questionnaire in order to assess the comprehension and acceptability of the instrument. statistical analysis was performed using the intraclass correlation coefficient (icc) and the kruskall-wallis non-parametric test to compare inter-rater data and using the icc and the non-parametric wilcoxon test to compare intra-rater data. results: high inter- (icc range 0.93-1.00) and intra-rater (icc range 0.80-0.97) reliability was found. there was excellent comprehension and acceptability of the scale. however, in some items there were questions on how to score the patients. conclusions: the portuguese version of the mas was shown to be a reliable assessment instrument and had excellent acceptability by the physical therapists. however, due to the questions on scoring, we suggest that the physical therapists receive training on how to apply the scale. further study is recommended on the validation of the translated version of this assessment instrument.

Abstract: croton pullei var. glabrior lanj. (euphorbiaceae) is a liana, vastly distributed in the amazonian forest. in the folk medicine, several plants of the croton genus have been used with therapeutic purposes in pathologies that involve painful and inflammatory diseases which justify this work. the aim of this study was to investigate the antinociceptive and antiinflammatory activities of the c. pullei leaves methanol extract (mecp). mecp reduced in a dose-dependent manner the number of acetic acid-induced abdominal writhing (1.2%) in mice, suggesting an antinociceptive activity of the plant. on the other hand, mecp did not significantly modify the reactivity to the thermal stimulation in the hot-plate test and the reactivity to the chemical stimulation in the formalin test first phase, indicating a non-opioid mechanism. mecp reduced the formalin-induced nociception in the second phase, inhibited the croton oil-induced ear edema and reduced the leukocytes migration in the test of the carrageenan-induced peritonitis, indicating an antiinflammatory activity. although the mechanisms that underlie these plant effects are not completely elucidated, these results appear to support the potential medicinal use of croton pullei var. glabrior lanj. against painful and inflammatory diseases.
