AUTONOMÍA UNIVERSITARIA: UNA MIRADA DESDE LO POLÍTICO
No full textEl trabajo es producto del proyecto de investigación sobre el Redimensionamiento de la esfera de lo público. Se trata de una discusión teórica sobre la universidad. El principio de autonomía sirve de hilo conductor para analizar el papel político de la universidad escindida entre el servicio al estado, a la sociedad, al mercado profesional y a la ciencia generada como valor en sí misma. Se reconstruye el principio de autonomía que inicia con una concepción instrumentalista de la relación universidad estado, pasa por el estudio de los procesos de transformación universitaria que serían ininteligibles al margen de la intervención de variables políticas tales como la presión de los intereses estatales, la militancia estudiantil y académica. Se reconoce una fase de aceptación de articulaciones específicamente políticas en la construcción del proyecto educativo. Finalmente, el intento de desarrollar una concepción de universidad integral que acepte explícitamente la articulación política con el todo social

No full textIn this letter, D.F. Goggin, Motor Officer, affirms that Tsugitada Kanamori was employed by his organization starting June 8, 1946 and was still employed there at the time this letter was written. He remarks that Kanamori is a loyal and honest employee and recommends him for any position.This collection contains one box of documents belonging to Tsugitada Kanamori.

Reconstruction of turbulent pipe-flow profiles from laser Doppler velocimetry data
No full textLaser Doppler velocimetry (LDV) is a powerful experimental tool that finds increasing application in industrial research and product development. For example, LDV may be used to support the development of water, heat, and cooling meters as well as the design and validation of the associated testing and calibration facilities. For such applications, a basic quantity of interest is the volume flow rate Q that can be determined through numerical integration of the velocity profile over the measurement grid. However, under realistic experimental conditions, optical disturbances and reflections may cause corrupted and unreliable data at various measurement points. Here, we study a criterium to identify and reconstruct such data points. The reconstruction criterium is based on the standard error associated with each measurement point. Using some of our LDV data, we show that the error in Q with respect to a reference flow rate may be reduced significantly through the reconstruction. Consequently, the reconstruction criterium allows to establish accurate and reliable flow rates that have potential to be used as a primary validation reference

Depolarization and decreased surface expression of K+ channels contribute to NSAID-inhibition of intestinal restitution
No full textNon-steroidal anti-inflammatory drugs (NSAIDs) contribute to gastrointestinal ulcer formation by inhibiting epithelial cell migration and mucosal restitution; however, the drug-affected signaling pathways are poorly defined. We investigated whether NSAID inhibition of intestinal epithelial migration is associated with depletion of intracellular polyamines, depolarization of membrane potential (Em) and altered surface expression of K+ channels. Epithelial cell migration in response to the wounding of confluent IEC-6 and IEC-Cdx2 monolayers was reduced by indomethacin (100μM), phenylbutazone (100μM) and NS-398 (100μM) but not by SC-560 (1μM). NSAID-inhibition of intestinal cell migration was not associated with depletion of intracellular polyamines. Treatment of IEC-6 and IEC-Cdx2 cells with indomethacin, phenylbutazone and NS-398 induced significant depolarization of Em, whereas treatment with SC-560 had no effect on Em. The Em of IEC-Cdx2 cells was: −38.5±1.8mV under control conditions; −35.9±1.6mV after treatment with SC-560; −18.8±1.2mV after treatment with indomethacin; and −23.7±1.4mV after treatment with NS-398. Whereas SC-560 had no significant effects on the total cellular expression of Kv1.4 channel protein, indomethacin and NS-398 decreased not only the total cellular expression of Kv1.4, but also the cell surface expression of both Kv1.4 and Kv1.6 channel subunits in IEC-Cdx2. Both Kv1.4 and Kv1.6 channel proteins were immunoprecipitated by Kv1.4 antibody from IEC-Cdx2 lysates, indicating that these subunits co-assemble to form heteromeric Kv channels. These results suggest that NSAID inhibition of epithelial cell migration is independent of polyamine-depletion, and is associated with depolarization of Em and decreased surface expression of heteromeric Kv1 channels.ID: S0006295207001931; M3: Article; Accession Number: S0006295207001931; Author: L.C.
