      The limits of copper homeostatic regulation in humans are not known, making it difficult to define the milder effects of early copper excess. Furthermore, a robust assay to facilitate the detection of early stages of ...
    • Spencer, Eugenio; Avendaño, Fidel; Araya, Magdalena (1983)
      Electropherotypes of human rotavirus from stool samples of hospitalized and ambulatory infants with acute diarrhea were analysed. Thirty-two different electropherotypes were observed in 142 cases in which the viral genome ...
