A difícil arte de "deslizar sobre o mundo" ou Montaigne, um político discreto ("De poupar a própria vontade" - III, 10)

De 1581 a 1585, Montaigne foi prefeito de Bordeaux. Foi acusado por detratores de não se ter aplicado o bastante e de não ter feito nada de marcante durante seus dois mandatos. Ao responder às acusações no ensaio "De poupar a própria vontade" (III, 10), o autor encontra a ocasião para uma crítica das paixões em geral e, em particular, das que pertencem ao contexto político. Isto porque ele visava, com sua aparente falta de aplicação aos deveres de prefeito, evitar a paixão que tantas vezes se oculta por trás do engajamento - a ambição, desejo de honras, glória, renome. Sobretudo, esperava evitar um duplo perigo, ao mesmo tempo ético e político: comprometer a própria liberdade numa busca servil da glória e subordinar o bem coletivo ao interesse pessoal. No presente estudo, procuraremos reconstituir a trama argumentativa do ensaio em questão, acompanhando de perto os argumentos que sustentam a crítica montaigniana das paixões, bem como a terapia muito particular a que o ensaísta as submete, a qual lhe permite fazer do episódio da Mairie de Bordeaux um modelo de conciliação entre o cuidado de si e o cumprimento dos deveres políticos.

Oxidative stress in the latissimus dorsi muscle of diabetic rats

The purpose of the present study was to investigate the effects of experimental diabetes on the oxidant and antioxidant status of latissimus dorsi (LD) muscles of male Wistar rats (220 ± 5 g, N = 11). Short-term (5 days) diabetes was induced by a single injection of streptozotocin (STZ, 50 mg/kg, iv; glycemia >300 mg/dl). LD muscle of STZ-diabetic rats presented higher levels of thiobarbituric acid reactive substances (TBARS) and chemiluminescence (0.36 ± 0.02 nmol/mg protein and 14706 ± 1581 cps/mg protein) than LD muscle of normal rats (0.23 ± 0.04 nmol/mg protein and 7389 ± 1355 cps/mg protein). Diabetes induced a 92% increase in catalase and a 27% increase in glutathione S-transferase activities in LD muscle. Glutathione peroxidase activity was reduced (58%) in STZ-diabetic rats and superoxide dismutase activity was similar in LD muscle of both groups. A positive correlation was obtained between catalase activity and the oxidative stress of LD, as evaluated in terms of TBARS (r = 0.78) and by chemiluminescence (r = 0.89). Catalase activity also correlated inversely with glutathione peroxidase activity (r = 0.79). These data suggest that an increased oxidative stress in LD muscle of diabetic rats may be related to skeletal muscle myopathy.

Measurement of the ultrasonic properties of human coronary arteries in vitro with a 50-MHz acoustic microscope

Ultrasonic attenuation coefficient, wave propagation speed and integrated backscatter coefficient (IBC) of human coronary arteries were measured in vitro over the -6 dB frequency bandwidth (36 to 67 MHz) of a focused ultrasound transducer (50 MHz, focal distance 5.7 mm, f/number 1.7). Corrections were made for diffraction effects. Normal and diseased coronary artery sub-samples (N = 38) were obtained from 10 individuals at autopsy. The measured mean ± SD of the wave speed (average over the entire vessel wall thickness) was 1581.04 ± 53.88 m/s. At 50 MHz, the average attenuation coefficient was 4.99 ± 1.33 dB/mm with a frequency dependence term of 1.55 ± 0.18 determined over the 36- to 67-MHz frequency range. The IBC values were: 17.42 ± 13.02 (sr.m)-1 for thickened intima, 11.35 ± 6.54 (sr.m)-1 for fibrotic intima, 39.93 ± 50.95 (sr.m)-1 for plaque, 4.26 ± 2.34 (sr.m)-1 for foam cells, 5.12 ± 5.85 (sr.m)-1 for media and 21.26 ± 31.77 (sr.m)-1 for adventitia layers. The IBC results indicate the possibility for ultrasound characterization of human coronary artery wall tissue layer, including the situations of diseased arteries with the presence of thickened intima, fibrotic intima and plaque. The mean IBC normalized with respect to the mean IBC of the media layer seems promising for use as a parameter to differentiate a plaque or a thickened intima from a fibrotic intima.
