    • ATPASE-ADPASE ACTIVITIES OF RAT PLACENTAL TISSUE 

      Pieber, M.; Valenzuela Pedevila, María Antonieta; Kettlun, Ana María; Mancilla, Marta; Aranda, E.; Collados, L. E.; Traverso Cori, A. (PERGAMON-ELSEVIER SCIENCE LTD, 1991)
      1. Calcium-stimulated ATPase-ADPase activities were studied in a microsomal fraction of rat placental tissue. 2. The kinetic characteristics correspond to those of ATP-diphosphohydrolase, also known as apyrase (E.C. ...
    • Hindered rotation of some substituted thioureas in complexes of chromium and tungsten carbonyls 

      Granifo, J.; Costamagna, J.; Garrao, A.; Pieber, M. (1980)
      We describe a procedure for the preparation of various metal thiourea complexes of the type [M(CO)5L] in which M Cr or W and L TU (thiourea), TMTU (tetramethylthiourea), DptTU (NN′-di-p-totyl thiourea); DtBTU = (NN′-di-t-butyl ...
    • II. On the construction of a phylogenetic tree 

      Toh¡,; Soto,; Pieber, (1979)
      For the construction of a phylogenetic tree an algorithm is described. This, allows the correction of the original data and the proper selection, in each step of the process, of the nearest neighbours of a common ancestor. ...
    • Radioprotection (UV- and gamma-rays) of DNA molecule by indole and indole-derivatives 

      Tomicic, I.; Pieber, M.; Romero, C.; Soto, A.; Tohá, J. C. (1973)
      The radioprotective ability of L-tryptophan, tryptamine, 3-indoleacetic and indole (10−4 m), on UV and gamma irradiated DNA (10−4 m) is studied. UV radioprotection is accomplished in the following order of efficiency: ...
