PRELIMINARY RESULTS OF RANDOM AMPLIFICATION OF POLYMORPHIC DNA AMONG TRIATOMINAE OF THE PHYLLOSOMA COMPLEX (HEMIPTERA, REDUVIIDAE)

Preliminary results of random amplification of polymorphic DNA among Triatominae of the phyllosoma complex (Hemiptera, Reduviidae)

In Mexico, Triatoma longipennis (Usinger), Triatoma picturata (Usinger), and Triatoma pallidipennis (Stal), primary Chagas disease vector species of the phyllosoma complex, were analyzed by randomly amplified polymorphic DNA (RAPD).Sixteen decametric primers resolved individual profiles not identical, but partially discriminative between species.An

Anthocyanins as functional food components

Among the natural pigments, anthocyanins are assumed to represent one of the most studied groups.Starting with the first studies on the physicochemical properties of anthocyanins carried out in the 17th century by British naturalist Robert Boyle, the science about these unique compounds has progressed substantially.To date, the structure and functi

Les substances radioactives dans les objets patrimoniaux

Odourless, noiseless and without any specifically perceptible physical form, the presence of radioactive substances HR Sensor Grip in patrimonial objects is not easily detectable.Therefore, the management of this particular patrimony appears problematic, on its practical as well as legal aspects.The fear of their noxiousness and the lack of knowled
