Enrique José Varona, intelectual cubano de gran prestigio durante la segunda mitad del siglo XIX y parte del siglo XX, efectuó una serie de consideraciones sobre la condición humana que fueron variando durante el transcurso de su vida. Estas van desde un positivismo sui generis, bajo influencias de Spencer, hasta posturas filantrópicas y de estimulación de la solidaridad entre los seres humanos, mediando entre ambas etapas un período de escepticismo y nihilismo bajo la influencia de Nietzsche. No fue un filósofo que se dejó atar a una postura ideológica cerrada en una corriente filosófica en particular. Fue capaz de analizar los problemas filosóficos y sociológicos con el mayor nivel de originalidad y autenticidad que sus circunstancias históricas le permitieron.

Los llamados “caballeros moriscos” eran cristianos de origen islámico que, a cambio de prestar servicio militar a la monarquía, cobraban un' salario en dinero y en especie. La mayoría vivían dispersos en ciudades de Castilla y de Andalucía, pero había un grupo cerca del rey de modo permanente. En el presente trabajo estudio las formas de reclutamiento de estos “caballeros”, subrayando el papel que juegan los vínculos familiares y sus medios de vida, que eran bastante escasos. También analizo la imagen deformada de esta minoría que nos ha transmitido algún cronista hostil a Enrique IV.

American cutaneous leishmaniasis (ACL) is an endemic disease in Northern Argentina. We applied the polymerase chain reaction (PCR) followed by a hybridization labelled probe to 21 paraffin embedded human skin biopsies, already analyzed histologically, from leishmaniasis endemic areas in the province of Tucumán, Argentina. We used primers previously designed to detect a Leishmania-specific 120-base-pair fragment of kinetoplast DNA minicircle, other two primer pairs that amplify kDNA minicircles belonging to the L. braziliensis and L. mexicana complexes respectively, and specific oligonucleotide primers to detect L. (V.) braziliensis which amplify the sequence of the ribosomal protein L-14 of this species. The PCR-hybridization showed a sensitivity of 90.5% when compared to the histopathology test which was 61.9%. Five of the total samples analyzed were positive for the L. braziliensis complex whilst none was positive for the L. mexicana complex. The specific primers for L. (V.) braziliensis detected the parasite in four samples. These results are consistent with those reported for close endemic areas and demonstrate that the causative agent of human leishmaniasis in the analyzed cases was L. (V.) braziliensis. PCR should be used as a diagnostic tool for tegumentary leishmaniasis, especially in the mucosal form, and as a valuable technique for the identification of the Leishmania species that causes the disease in certain areas.

The aim of the present study was to assess the possible use of a modified medium, prepared in the laboratory using the constituents of Barbour-Stonner-Kelly (BSK) medium and medium 199 as base, for the culture of Borrelia strains, comparing the growth of individual strains in this medium and in the BSK-H medium, and the protein profile and antigenic characteristics of Borrelia proteins expressed in these media. A qualitative evaluation of growth of Borrelia species was made with acceptable results (morphology and motility), but during a quantitative evaluation using the three main genospecies of Borrelia, the better results were obtained with a B. burgdorferi sensu stricto strain. The modified medium did not enable the growth of a B. afzelii strain. The protein profile and antigenic characteristic of the expressed proteins in the modified medium were studied with satisfactory results. These results suggest the modified medium as an alternative for the cultivation of Borrelia strains, with some limitations, in poorly-resourced laboratories.
