Datos preliminares sobre fuentes de aprovisionamiento de rocas silíceas en algunos yacimientos paleolíticos y postpaleolíticos del sector oriental de la cuenca vasco-cantábrica

[ES] Exponemos en este trabajo los primeros resultados referentes a las áreas de aprovisionamiento de materiales silíceos en el sector oriental de la Cuenca Vasco-Cantábrica durante el Pleistoceno superior y Holoceno. Se describen aquellos afloramientos cuyos sílex han sido identificados en varios yacimientos del periodo contemplado. Hemos constatado una transformación sustancial de las estrategias de aprovisionamiento, observable a fines del Paleolítico y especialmente significativa desde el Epipaleolítico. Asimismo, las pautas de ocupación del territorio reflejadas muestran indicios de un aprovechamiento rentable, estacional, de tierras en torno a los 600 m.s.n.m. durante el Pleistoceno superior, y con territorios de explotación probablemente de mayor extensión que los contemplados hasta el momento por la historiografía del Paleolítico cantábrico.

Sensing parasites: proteomic and advanced bio-detection alternatives

[EN] Parasitic diseases have a great impact in human and animal health. The gold standard for the diagnosis of the majority of parasitic infections is still conventional microscopy, which presents important limitations in terms of sensitivity and specificity and commonly requires highly trained technicians. More accurate molecular-based diagnostic tools are needed for the implementation of early detection, effective treatments and massive screenings with high-throughput capacities. In this respect, sensitive and affordable devices could greatly impact on sustainable control programmes which exist against parasitic diseases, especially in low income settings. Proteomics and nanotechnology approaches are valuable tools for sensing pathogens and host alteration signatures within microfluidic detection platforms. These new devices might provide novel solutions to fight parasitic diseases. Newly described specific parasite derived products with immune-modulatory properties have been postulated as the best candidates for the early and accurate detection of parasitic infections as well as for the blockage of parasite development. This review provides the most recent methodological and technological advances with great potential for biosensing parasites in their hosts, showing the newest opportunities offered by modern “-omics” and platforms for parasite detection and control.
