A maldade na encruzilhada do século XIX: Franklin Távora e O Cabeleira

O romance O Cabeleira, de Franklin Távora, é considerado um marco do regionalismo literário brasileiro. De difícil defi nição, situa-se numa encruzilhada de períodos, estilos, tradições e ideologias, donde emerge uma perspectiva já incompatibilizada com o antigo regime, porém ainda caudatária de idéias românticas. A questão da maldade, muito presente na narrativa, aponta tais confl uências e problemas, explicitando os limites da visão de mundo do autor.

Coliform density in oyster culture waters and its relationship with environmental factors

The objective of this work was to evaluate the total and thermotolerant coliform densities in the oyster culture water of Cananeia, SP, Brazil, correlating these densities with environmental variables and tidal variations. Superficial water samples were collected in two tide conditions (spring and neap) from three areas of Cananéia municipality (Mandira, Itapitangui and Cooperostra). The three studied areas showed good conditions for the culture regarding coliform densities. The two tidal conditions differed significantly as to total coliform concentration; however, the same procedure was not performed for thermotolerant coliforms. No correlation was observed between water temperature, pH, and concentrations of total and thermotolerant coliforms. Coliform density was positively correlated with rainfall and negatively correlated with salinity. Spring and neap tides differed significantly as to coliform number. Simple diagnosis of environmental conditions of the crop fields is insufficient to assess water quality of shellfish cultivation. A continuous monitoring program of planted areas is necessary both for the assessment of water quality potential for marine culture and for ensuring safe consumption of seafood, besides constituting an important tool to understand the relationships between contamination and the involved environmental variables.

B-type natriuretic peptide in the evaluation of cardiac function

B type natriuretic peptide (BNP) and its precursor, the inactive form of NT-pro-BNP, are currently the most studied laboratory parameters in the heart disease spectrum. The assessment of their blood concentrations provides invaluable information on the likelihood, severity and prognosis of the disease. The present review aims to describe the biological determinants, the factors that influence these peptide concentrations, the suggested cutoff values for the diagnosis of heart failure and the use of this biomarker in the assessment of cardiac function.

A new method to evaluate glenoid erosion in instable shoulder

Background: We aimed to establish values and parameters using multislice reconstruction in axial computerized tomography (CT) in order to quantify the erosion of the glenoid cavity in cases of shoulder instability. Methods: We studied two groups using CT. Group I had normal subjects and Group II had patients with shoulder instability. We measured values of the vertical segment, the superior horizontal, medial and inferior segments, and also calculated the ratio of the horizontal superior and inferior segments of the glenoid cavity in both normal subjects and those with shoulder instability. These variables were recorded during arthroscopy for cases with shoulder instability. Results: The mean values were 40.87 mm, 17.86 mm, 26.50 mm, 22.86 mm and 0.79 for vertical segment, the superior horizontal, medial and inferior segments, and the ratio between horizontal superior and inferior segments of the glenoid cavity respectively, in normal subjects. For subjects with unstable shoulders the mean values were 37.33 mm, 20.83 mm, 23.07 mm and 0.91 respectively. Arthroscopic measurements yielded an inferior segment value of 24.48 mm with a loss of 2.39 mm (17.57%). The ratio between the superior and inferior segments of the glenoid cavity was 0.79. This value can be used as a normative value for evaluating degree of erosion of the anterior border of the glenoid cavity. However, values found using CT should not be used on a comparative basis with values found during arthroscopy. Conclusions: Computerized tomographic measurements of the glenoid cavity yielded reliable values consistent with those in the literature.

Heparin and dextran sulfate: their role on rsv infectivity

Respiratory syncytial virus is the major cause of acute lower respiratory tract illness in infants and young children. Because there is currently no licensed vaccine for RSV, there is a substantial interest in the identification and development of RSV specific inhibitory agents. There are clinical evidences that glycosaminoglycans (GAGs) are potential inhibitors of viral infection. In this study, the performance of two GAGs (heparin and dextran sulfate) were compared for their antiviral and virucidal activities on RSV. Analysis was performed using an in vitro infection model where, previously to infection, Hep-2 cells or RSV were incubated with heparin or dextran sulfate. The presence of viral particles was analyzed by Reverse Transcriptase-Polimerase Chain Reaction (RT-PCR) and indirect immunofluorescence assays (IFA). The results showed that viral infection was more efficiently inhibited when Hep-2 cells were pre-incubated with heparin or, when viral particles were pre-incubated with dextran sulfate. Our study suggest that, in the absence of cellular death, heparin and dextran sulfate reduce RSV infection by different mechanisms, antiviral and virucidal ones, respectively. These data contribute for recent medical, microbiology and biochemical studies which suggest that the use of antiviral and virucidal compounds as more effective treatment to control virus infections.

Analysis of Climatic Factors Impact on RSV Infection Distribution in Children Attending Childcare at Northwest Region of São Paulo, Brazil

Respiratory syncytial virus (RSV) was detected in samples collected from children from 0 to 6 years of age with acute respiratory infection, attending public childcare on Northwest region of São Paulo, Brazil. RSV distribution was associated to seasonal climatic variables as temperature, rainfall and relative air humidity. We utilized samples of nasopharyngeal aspirate collected during the period of July 2003 to September 2005. RT-PCR was the chosen method for viral identification. Results showed that from the 817 samples (collected from 179 children), 7.7% (63/817) were RSV positive. In 2003, RSV was detected from July until October. In 2004, RSV infections occurred in March, May, June, July, October, November, and December. In 2005, RSV was detected in March, April, May, August, and September. RSV circulation patterns in childcare children showed seasonal distribution associated to decreases in temperature and relative air humidity. RSV was detected in childcare children as an important viral agent causing respiratory infections, with varying patterns of circulation into the cohort during the study period. Moreover, RSV distribution showed to be associated with the dry season on Northwest region of São Paulo, Brazil.
