    • Aumento del daño en el ADN espermático en varones mayores de 40 años 
      Horta, Fabrizzio; Madariaga, Marcia; García, Alejandra; Härtel, Steffen; Smith Garcés, Rosita (SOC MEDICA SANTIAGO, 2011-03)
      Background: There is an association between aging and an increased number of sperms with alterations in nuclear DNA. Aim: To study the association between age and fragmentation of sperm DNA. Material and Methods: Sixty two ...
    • Changes in mitochondrial dynamics during ceramide-induced cardiomyocyte early apoptosis 
      Parra Ortíz, María Valentina; Eisner, Verónica; Chiong Lay, Mario; Criollo Céspedes, Alfredo; Moraga, Francisco; García, Alejandra; Haertel, Steffen; Jaimovich Pérez, Enrique; Zorzano, Antonio; Hidalgo Tapia, María Cecilia; Lavandero González, Sergio (ELSEVIER SCIENCE BV, 2008-01-15)
      Aims In cells, mitochondria are organized as a network of interconnected organelles that fluctuate between fission and fusion events (mitochondrial dynamics). This process is associated with cell death. We investigated ...
    • Gold-standard for computer-assisted morphological sperm analysis 
      Chang, Violeta; García, Alejandra; Hitschfeld Kahler, Nancy; Härtel, Steffen (Elsevier, 2017)
      Background and Objective: Published algorithms for classification of human sperm heads are based on relatively small image databases that are not open to the public, and thus no direct comparison is available for competing ...
    • Membrane electrical activity elicits inositol 1,4,5-trisphosphate-dependent slow Ca2+ signals through a ... 
      Eltit Ortega, José Miguel; García, Alejandra; Hidalgo, Jorge; Liberona, José L.; Chiong Lay, Mario; Lavandero González, Sergio; Maldonado, Edio; Jaimovich Pérez, Enrique (American Society for Biochemistry and Molecular Biology Inc., 2006)
      Tetanic electrical stimulation of myotubes evokes a ryanodine receptor-related fast calcium signal, during the stimulation, followed by a phospholipase C/inositol 1,4,5-trisphosphate-dependent slow calcium signal few seconds ...
    • Nanoscale zero valent supported by Zeolite and Montmorillonite: Template effect of the removal of lead ion ... 
      Arancibia Miranda, Nicolás; Baltazar, Samuel E.; García, Alejandra; Muñoz Lira, Daniela; Sepúlveda, Pamela; Rubio, María A.; Altbir, Dora (Elsevier, 2016)
      In this work, we have studied the Pb2+ sorption capacity of Zeolite (Z) and Montmorillonite (Mt) functionalized with nanoscale zero-valent iron (nZVI), at 50% w/w, obtained by means of an impregnating process with a solvent ...
    • Ryanodine receptor-mediated Ca2+ release underlies iron-induced mitocondrial fission and stimulates ... 
      San Martín Rovirosa, Carol; Paula Lima, Andrea; García, Alejandra; Barattini, Pablo; Hartel, Steffen; Núñez González, Marco; Hidalgo Tapia, María Cecilia (2014)
      Mounting evidence indicates that iron accumulation impairs brain function. We have reported previously that addition of sub-lethal concentrations of iron to primary hippocampal neurons produces Ca2+ signals and promotes ...
