      The amphibian genus Telmatobius is a diverse group of species that inhabits the Andes. This study analysed the phylogenetic relationships of 19 species described from the central Andes of Chile and Bolivia, and 12 undescribed ...
    • Biogeography of Chilean herpetofauna: Distributional patterns of species richness and endemism

      The description of a new species of Eupsophus, from Los Queules National Reserve (35° 59' S, 72° 41'W) adds a new endemic taxon to the fauna of telmatobines (Amphibia, Leptodactylidae) of Chile, and extends the geographical ...
    • Diagnostic value of detecting specific IgA and IgM with recombinant Trypanosoma cruzi antigens in congenital Chagas' disease 

      Lorca,; Veloso,; Munoz,; Bahamonde,; GARCIA, (American Society of Tropical Medicine and Hygiene, 1995)

      Veloso Iriarte, Claudio; Bozinovic Kuscevic, Francisco (1993)
      McNab (1986, 1988) has hypothesized that mammals using food with low energy content should exhibit basal metabolic rates (BMR) lower than those expected on the basis of their body mass (mb). That is, those species that ...

      Méndez, Marco A.; Soto, Eduardo R.; Correa, Claudio; Veloso,; Vergara, Eliseo; Sallaberry Ayerza, Michel; Iturra, Patricia (Sociedad de Biologia de Chile, 2004)
      Bufo spinulosus has a wide and fragmented distribution range in Chile (18° to 33° S) along altitudinal and latitudinal gradients. Genetic variation was estimated using RAPD (Random Amplified Polymorphic DNA) markers in 10 ...
    • Respiratory refinements in the mygalomorph spider Grammostola rosea Walckenaer 1837 (Araneae, Theraphosidae) 

      Canals,; Salazar,; Durán,; Figueroa,; Veloso, (2007)
      In this study we hypothesized that Grammostola rosea Walckenaer 1837, an active predator of large size that depends on its two paired book lungs for respiration, would have a refined low energy strategy based on its thin ...
    • The diagnosis of chronic Chagas disease using recombinant antigens of Trypanosoma cruzi El diagnóstico de la enfermedad de Chagas crónica mediante antígenos recombinantes de Trypanosoma cruzi. 

      Lorca,; González González, Larry Javier; Reyes Reyes, Consuelo; Veloso,; Vergara Vergara, Geraldine; Frasch, (1993)
      A panel of eight recombinant Trypanosoma cruzi antigens was used to study the IgG reactivity of sera proceeding from 151 patients with chronic Chagas disease. These samples were reactive against T Cruzi epimastigotes by ...
