Dipsacus asperoides (Xue Duan) inhibits spinal cord injury-induced inflammatory responses in rats

Purpose: To investigate the effect of Dipsacus asperoides (Xue Duan), a traditional Chinese medicine, on rats with spinal cord injury (SCI). Methods: In this study a total of 40 adult rats were used after inducing SCI where Xue Duan was applied on experimental group and phosphate-buffered saline (PBS) was administered in corresponding control groups. Intraperitoneal administration of both compounds for a period of four weeks (28 days) was carried out at a dose of 10 mg/kg/day. Bright field microscopy was performed on the tissues. Results: Bright Field microscopy of tissue sections showed significant reduction in cavity area that resulted from injury, that is from 0.19 ± 0.05 mm2 to 0.09 ± 0.03 mm2 (p < 0.01) in untreated and treated groups respectively. Similarly western blotting results showed a decrease in the expression of NF-kB p65 and I-kBα (p < 0.01). These two compounds are important in increasing secondary pathophysiology in SCI. The results for MPO activity also revealed significantly reduced infiltration of leukocytes to the injury site (p < 0.01). Conclusion: This study reveals the positive effect of the plant material in reducing inflammation in rats with traumatic SCI.

Habilitadores y habilitados en el Valle Central de Costa Rica. El financiamiento de la producción cafetalera en los inicios de su expansión (1838-1850)

ResumenEn una época en que todo se estaba reestructurando, habilitado, habilitador, habilitación carecieron de un significado socio-económico preciso. El habilitado no era siempre un explotado, y el habilitador eventualmente podía serlo. La habilitación era a veces una relación mercantil entre capitalistas, mientras que en otras ocasiones era un mecanismo para extraer el excedente agrario.AbstractAt a time when all was being restructured, the terms habilitado; habilitador and habilitación lacked a precise socioeconomic meaning. Habilitados were not always exploited, and habilitadores might be subject to exploitation. Habilitación was sometimes a mercantile relation between capitalists, while other times it was a mechanism to extract agrarian surplus.

La unificación nacional que dejó una nación dividida. El gobierno del Presidente Zelaya y la ‘reincorporación’ de la Mosquitia a Nicaragua en 1894

ResumenExamina los motivos y la actuación política del gobierno liberal encabezado por le presidente José SANTOS Zelaya, en la fase inicial de las reincorporación de la Mosquita a Nicaragua. Los conceptos vigentes de territorio, soberanía y progreso material pasaron por alto los derechos legítimos de la población costeña.AbstractAn analysis of the motivations and political conduct of the Liberal government headed by President José Santos Zelaya, during the early stage of reincorporation of Mosquitia to Nicaragua. The prevailing concepts with respect to territory, sovereignty, and material progress did not take into account the legitimate rights of the coastal inhabitants.

High-flux ceramic membranes with a nanomesh of metal oxide nanofibers

Traditional ceramic separation membranes, which are fabricated by applying colloidal suspensions of metal hydroxides to porous supports, tend to suffer from pinholes and cracks that seriously affect their quality. Other intrinsic problems for these membranes include dramatic losses of flux when the pore sizes are reduced to enhance selectivity and dead-end pores that make no contribution to filtration. In this work, we propose a new strategy for addressing these problems by constructing a hierarchically structured separation layer on a porous substrate using large titanate nanofibers and smaller boehmite nanofibers. The nanofibers are able to divide large voids into smaller ones without forming dead-end pores and with the minimum reduction of the total void volume. The separation layer of nanofibers has a porosity of over 70% of its volume, whereas the separation layer in conventional ceramic membranes has a porosity below 36% and inevitably includes dead-end pores that make no contribution to the flux. This radical change in membrane texture greatly enhances membrane performance. The resulting membranes were able to filter out 95.3% of 60-nm particles from a 0.01 wt % latex while maintaining a relatively high flux of between 800 and 1000 L/m2·h, under a low driving pressure (20 kPa). Such flow rates are orders of magnitude greater than those of conventional membranes with equal selectivity. Moreover, the flux was stable at approximately 800 L/m2·h with a selectivity of more than 95%, even after six repeated runs of filtration and calcination. Use of different supports, either porous glass or porous alumina, had no substantial effect on the performance of the membranes; thus, it is possible to construct the membranes from a variety of supports without compromising functionality. The Darcy equation satisfactorily describes the correlation between the filtration flux and the structural parameters of the new membranes. The assembly of nanofiber meshes to combine high flux with excellent selectivity is an exciting new direction in membrane fabrication.
