Methods: Serum specimens from 247 persons randomly selected from the population of the village were examined by IgG Western blot using B31 strain for estimating the prevalence of antibodies profile.Results: A seroprevalence value interval (95% CI) of 0.6%-7.2% was estimated for the studied population. The prevalent borrelial protein bands on immunoblots were 41, 72, 90/93, 34, 47, 60, 58, 56, 65/66 and 31 kDa in a decreasing order of significance. Conclusion:These results support the previous serological findings, suggesting the presence of this borreliosis in Cuba.

La muerte como proceso: una perspectiva antropológica

2 Bajo la denominación maligno o malo resuenan los ecos de la figura que el discurso cristiano ha llamado demonio. Volveré sobre este punto. Resumen En San Antonio, Catamarca, Argentina, la disputa entre las fuerzas de Dios y Cristo, y el maligno es narrada por la gente del lugar como un principio ordenador del mundo. En ella, las personas toman partido activamente a través de la acción ritual. En este artículo presento y discuto cómo esta pugna se plasma en el ciclo anual y el ciclo diario. En particular, sugiero que los lazos cosmológicos que se expresan anualmente se reiteran a escala diaria, de modo que la jornada resulta una repetición microcósmica que se instaura bajo similares principios organizativos que el ciclo anual. Palabras claves: cosmología-tiempo-ritual. Abstract In San Antonio, Catamarca, Argentina, the dispute between God and Christ's forces, and evil's is narrated by the locals as a world's ruling principle. In it, people take active participation through the ritual action. In this article I present and discuss how this conflict is shaped in the yearly and daily cycles. In particular, I suggest the cosmological liaisons that are expressed annually, are repeated on a daily basis, in a way that the day results in a microcosmic repetition that is presented under similar organizing principles to those of the yearly cycle.

Biodegradable microspheres of PLGA (75:25 and 50:50) containing Ciprofloxacin (CIPRO) were prepared by two different procedures based on: (i) solvent-evaporation, and (ii) evaporation-extraction of the organic phase. The encapsulation rates from the different formulations were quite variable, as well the release patterns of the drug from the microspheres. The evaporation-extraction method seems to be more efficient for the CIPRO encapsulation compared with the solvent evaporation method. The 50:50 PLGA composition released the drug faster and showed degradation signs after incubation in aqueous medium in both manufacturing methodologies.
