Patočka y Diotima. Notas para un diálogo sobre lo bello
No full textNegative Platonism is perhaps one of Jan Patočka's texts that has received the most attention in the academic world. Its importance is rarely doubted. However, today we are far from exhausting the implications of the Czech philosopher's interpretation of Plato. In particular, the conception of the Platonic Idea that derives from Patočka's reading does not seem to have been sufficiently confronted with what Plato himself said in his dialogues. According to the author, there seems to be a particular affinity between what Diotima says in her speech in the Symposium and Patočka's interpretation of Plato, which, until now, does not seem to have received enough attention in the academic literature on these two authors. In a similar way to what Patočka proposes with the experience of freedom as a door that opens to the consideration of the Idea, Diotima anchors the recognition of beauty in itself with the experience of beauty in the world. This "anchoring" would be given by the ascending path proposed in the scala amoris, in which eros, assumes an “integrative function” within the lover. Precisely, this integrative function carried out by eros seems to give reason to the link that Diotima establishes between that which is beauty in itself and the true virtue that the lover engenders by experiencing it.Platonismo negativo es quizás uno de los textos de Jan Patočka que más atención ha recibido en el ámbito académico. Su importancia es pocas veces puesta en duda. Con todo, hoy nos encontramos lejos de agotar las implicaciones que conlleva la interpretación que hace de Platón el filósofo checo. Particularmente, la concepción de la Idea platónica que se deriva de la lectura patočkiana, no parece haber sido suficientemente confrontada con lo dicho por el mismo Platón en sus diálogos. Según el autor, parece existir una afinidad particular entre lo dicho por Diotima en su discurso en el Banquete y la interpretación patočkiana de Platón que, hasta el momento, no parece haber recibido suficiente atención en la literatura académica sobre estos dos autores. De manera similar a lo que plantea Patočka con la experiencia de la libertad como puerta que abre a la consideración de la Idea, Diotima ancla el reconocimiento de lo bello en sí con la experiencia de lo bello en el mundo. Este “anclaje” se daría gracias al camino en ascenso planteado en la scala amoris, en el que eros, siendo amor de lo bello, asume una función integradora en el interior del amante. Justamente, esta función integradora llevada a cabo por eros parece dar razón del vínculo que establece Diotima entre aquello que es bello en sí mismo y la virtud verdadera que el amante engendra al experimentarlo

Effects of sodium orthovanadate on whole kidney and single nephron function
No full textEffects of sodium orthovanadate on whole kidney and single nephron function. The renal effects of sodium vanadate (Na3VO4), an inhibitor of sodium-potassium-ATPase recently shown to be a potent diuretic, were studied by using clearance and micropuncture techniques in nondiuretic anesthetized rats. Administration of 1.0 µmole of sodium vanadate (high dose) increased urine flow rate (V) from 9.8 ± 1.4 to 17.5 ± 4.0 µl/min (mean ± SEM, P < 0.025), UNaV from 1.73 ± 0.36 to 3.05 ± 0.65 µEq/min (P < 0.025), and FENa from 0.67 ± 0.15 to 1.24 ± 0.28% (P < 0.025). No significant changes in GFR or RPF were observed. Late proximal tubular-fluid-to-plasma (F/P) inulin decreased from 2.28 ± 0.19 to a minimum value of 1.38 ± 0.06 (P < 0.025). Absolute water reabsorption decreased from 15.8 ± 3.5 to 6.5 ± 1.7 nl/min ( P < 0.025) and fractional water reabsorption from 52.0 ± 4.4 to 26.5 ± 4.1% (P < 0.025). The injection of 0.5 µmole of sodium vanadate (low dose) resulted in no significant changes in V. Late proximal F/P inulin decreased, however, from 2.37 ± 0.14 to a minimum value of 1.59 ± 0.12 (P < 0.025). SNGFR remained unchanged, as did GFR and RPF. UNaV increased from 1.41 ± 0.35 to 2.25 ± 0.35 µEq/min (P < 0.025), and FENa rose from 0.64 ± 0.16 to 0.91 ± 0.15% (P < 0.025). The decrease in F/P inulin was observed in all but one animal, even in the absence of a diuretic response. The amount of fluid remaining in the lumen of the late proximal tubule was virtually the same in both low- and high-dose animals (18.9 ± 3.0 and 19.5 ± 3.4 nl/ min, respectively). We conclude that sodium vanadate causes a decrease in superficial proximal tubule fluid and salt reabsorption. Inasmuch as the low dose does not result necessarily in a diuretic response, an increase in fluid reabsorption distal to the late proximal tubule must take place.Effets de l'orthovanadate de sodium sur la fonction du rein entier et des néphrons individuels. Les effets rénaux du vanadate de sodium (Na3VO4), un inhibiteur de la sodium-potassium-ATPase dont il a été montré récemment qu'il est un diurétique puissant, ont été étudiés au moyen des techniques de clearance et de microponction chez des rats anesthésiés non diurétiques. L'administration de 1,0 µmole de vanadate de sodium (dose élevée) a augmenté le débit urinaire (V) de 9,8 ± 1,4 à 17,5 ± 4,0 µl/min (moyenne ± SEM, P < 0,025), UNa de 1,73 ± 0,36 à 3,05 ± 0,65 µEq/min (P < 0,025) et FENa de 0,67 ± 0,15 à 1,24 ± 0,28% (P < 0,025). Il n'a pas été observé de modification significative de GFR ou RPF. Le rapport inuline tubulaire/inuline plasmatique (F/P inulin) à la fin du tube proximal a diminué de 2,28 ± 0,19 à une valeur minimale de 1,38 ± 0,06 (P < 0,025). La réabsorption absolue d'eau a diminué de 15,8 ± 3,5 à 6,5 ± 1,7 nl/min (P < 0,025) et la réabsorption fractionnelle d'eau de 52,0 ± 4,4 à 26,5 ± 4,1% (P < 0,025). L'injection de 0,5 µmoles de vanadate de sodium (dose faible) n'a pas déterminé de modification significative de V. Le rapport inuline tubulaire/inuline plasmatique à la fin du proximal, cependant, a diminué de 2,37 ± 0,14 à une valeur minimale de 1,59 ± 0,12 (P < 0,025). SNGFR est resté inchangé, de même que GFR et RPF. UNa a augmenté de 1,41 ± 0,35 à 2,25 ± 0,35 µEq/min (P < 0,025) et FENa a augmenté de 0,64 ± 0,16 à 0,91 ± 0,15% (P < 0,025). La diminution de F/P inuline a été observée chez tous les animaux sauf un, même en l'absence de réponses diurétique. La quantité de liquide présent dans la lumière à la fin du tube proximal était pratiquement la même que la dose administrée ait été faible ou forte (18,9 ± 3,0 et 19,5 ±3,4 nl/min, respectivement). Nous concluons que vanadate de sodium détermine une diminution de la réabsorption d'eau et de sel par les tubes proximaux superficiels. Du fait que la dose faible n'entraîne pas toujours une réponse diurétique une augmentation de la réabsorption d'eau en aval de la fin du tube proximal doit exister

LÍNEAS MAESTRAS DE LA GRAMÁTICA CASTELLANA DE ANDRÉS BELLO
No full textResumen:El trabajo es continuación y actualización de otros trabajos del autor sobre la célebre Gramática de la lengua castellana destinada al uso de los americanos de Andrés Bello. Seguimos en parte la labor emprendida por Rufino José Cuervo al abordar las líneas maestras de esta gramática tan importante durante siglo y medio en los países de habla castellana.Se investigan sus principios fundamentales y no tanto los usos del castellano Se discute su dependencia e independencia de la Gramática General de Port-Royal. En las partes de la oración el trabajo se fija especialmente en la jerarquía de las partes de la oración (Jespersen). Se destaca la semejanza de la definición de verbo con el estoicismo (Crisipo). Se insiste en la novedad para su tiempo de la definición de preposición. También se nota la deficiencia en el estudio de los nexos hipotácticos. Es pues un estudio en parte teórico, en parte histórico, que quiere ser crítico y sistemático.Palabras Claves: Gramática, Andrés Bello, preposición, estoicismo, Gramática General de Port-Royal.Abstract:The work is continuation and the updating of other works of the author on the brain Gramática of the Castilian language destined to the use of the Americans of Andrés Bello. We continue in the part of the workmanship by Rufino José Cuervo when approaching the main lines of this grammar so important during the century and a half in the countries of Castilian speaking. Its fundamental principles are investigated and not so much the uses of the castle it is discussed its Dependence and independence of the General Grammar of Port-Royal. . In the parts of the sentence the work is especially focused on the hierarchy of parts of the sentence (Jespersen). The similarity of the definition of verb with stoicism (Chrysippus) stands out. It insists on the novelty for the time of the definition of preposition. There is also a deficiency in the study of hypothetical nexus. It is therefore a partly theoretical, partly historical, study that wants to be critical and systematic.Key Words: Grammar, Andrés Bello, preposition, stoicism, General Grammar of Port-Royal
