    • González, Gustavo; Celedón, Gloria; Sandoval, Mario; González, Gabriela E.; Ferrer, Verónica; Astete, Rodrigo; Behn Thiele, Claus (2002)
      We have previously shown that subjects exposed to acute hypobaric hypoxia display an erythrocyte membrane protein band 3 with an increased susceptibility to proteolytic degradation. We suggested it was due to an oxidative ...
    • Demoro, Bruno; Rostan, Santiago; Moncada, Mauricio; Li, Zhu Hong; Docampo, Roberto; Olea Azar, Claudio; Maya Arango, Juan; Torres, Julia; Gambino, Dinorah; Otero, Lucia (Springer, 2018)
      To face the high costs of developing new drugs, researchers in both industry and academy are looking for ways to repurpose old drugs for new uses. In this sense, bisphosphonates that are clinically used for bone diseases ...
    • iordano, Ady; Vásquez, José; Retamal, Mauricio; Ascar Estay, María Loreto (Sociedad Brasileira de Quimica, 2016)
      The use of thin-film microextraction for the extraction of selected pharmaceutical compounds followed by gas chromatography-mass spectrometry detection was evaluated. A segment of polysiloxanes polymer sheet was used as ...

      Se desarrolló un protocolo de reconocimiento de barnices empleados en pintura de caballetes utilizando Cromatografía en Placa Fina (TLC). La identificación del barníz se realizó comparando el perfil de elusión cromatográfico ...
    • Varela, Patricia; Jerez, Carlos A. (1992)
      The major heat shock proteins from Thiobacillus ferrooxidans were identified as DnaK and GroEL equivalents by Western blotting and analysis of the N-terminal amino acid sequence of spots isolated from dried 2-D polyacrylamide ...
    • Kettlun, Ana María; Leyton, Mario; Valenzuela, María Antonieta; Mancilla, Marta; Traverso Cori, A. (1992)
      Two forms of ATP-diphosphohydrolase were identified in Solanum tuberosum tuber var. Ultimus. Their hydrolytic activity ratios (ATPase/ADPase) were over 10 for form A and 1 for form B. In the potato tuber homogenate the ...
