    • A role for reactive oxygen/nitrogen species and iron on neuronal synaptic plasticity 
      Hidalgo Tapia, María Cecilia; Carrasco, M. Angélica; Muñoz, Pablo; Núñez González, Marco (2007)
      A great body of experimental evidence collected over many years indicates that calcium has a central role in a variety of neuronal functions. In particular, calcium participates in synaptic plasticity, a neuronal process ...
    • Aging impairs hippocampal- dependent recognition memory and LTP and prevents the associated RyR up-regulation 
      Arias Cavieres, Alejandra; Adasme, Tatiana; Sánchez, Gina; Muñoz, Pablo; Hidalgo Tapia, María Cecilia (Frontiers Research Foundation, 2017)
      © 2017 Arias-Cavieres, Adasme, Sánchez, Muñoz and Hidalgo.Recognition memory comprises recollection judgment and familiarity, two different processes that engage the hippocampus and the perirhinal cortex, respectively. ...
    • Analysis of the condyle, articular fossa and mandibular ramus in subjects with active condylar hyperplasia 
      Muñoz, Pablo; Rangel Goulart, Douglas; Olate, Sergio; De Moraes, Márcio; Navarro, Pablo; Fariña, Rodrigo (Universidad de la Frontera, 2014)
      All rights reserved.Facial asymmetry is relatively common, but it becomes a disease when condylar hyperplasia is involved. The purpose of this investigation was to describe and compare the morphological characteristics of ...
    • Artificial intelligence for the early detection of colorectal cancer: A comprehensive review of its advantages ... 
      Viscaino, Michelle; Torres Bustos, Javier; Muñoz, Pablo; Auat Cheein, Cecilia; Auat Cheein, Fernando (Baishideng, 2021)
      Colorectal cancer (CRC) was the second-ranked worldwide type of cancer during 2020 due to the crude mortality rate of 12.0 per 100000 inhabitants. It can be prevented if glandular tissue (adenomatous polyps) is detected ...
    • Astaxanthin protects primary hippocampal neurons against noxious effects of A β-oligomers 
      Lobos, Pedro; Bruna, Barbara; Cordova, Alex; Barattini, Pablo; Galáz, Jose Luis; Adasme, Tatiana; Hidalgo Tapia, María Cecilia; Muñoz, Pablo; Paula Lima, Andrea (Hindawi Limited, 2016)
      © 2016 Pedro Lobos et al.Increased reactive oxygen species (ROS) generation and the ensuing oxidative stress contribute to Alzheimer's disease pathology. We reported previously that amyloid-β peptide oligomers (AβOs) produce ...
    • Bridge to lung transplantation with a novel pumpless lung assist device. Report of one case Uso del dispositivo ... 
      Fernández, Patricio; Muñoz, Pablo; Fischer, Danilo; Méndez, Felipe; Florenzano Valdés, Matías; Valdés, Sergio; Parada, María Teresa; Fica, Mauricio; Rodríguez, Patricio; Díaz, Rodrigo; Rufs, Jorge (2009)
      Devices such as Novalung® can be used as a bridge to lung transplantation while waiting for a suitable donor. We report a 50 year-old male with a terminal pulmonary fibrosis and candidate for lung transplantation. He was ...
    • Effect of iron on the activation of the MAPK/ERK pathway in PC12 neuroblastoma cells 
      Muñoz, Pablo; Zavala, Gabriela; Castillo, Karen; Aguirre, Pabla; Hidalgo Tapia, María Cecilia; Núñez González, Marco (2006)
      Recent evidence suggests that reactive oxygen species function as second messenger molecules in normal physiological processes. For example, activation of N-Methyl-D-Aspartate receptor results in the production of ROS, ...
    • Helicobacter pylori infection detected during upper gastrointestinal endoscopy Disminución en la frecuencia ... 
      da Costa, Daniel; Guidotti, Francesca; Cabello, Nicolas; Trigo, Francisco; Contreras, Caterina; Vergara, Francisca; Miranda, Juan Pablo; Montenegro, Cristián; Muñoz, Pablo; Berger, Zoltán (Sociedad Medica de Santiago, 2018)
      © 2018, Sociedad Medica de Santiago. All rights reserved.Background: Helicobacter pylori (HP) is the most widespread chronic human infection worldwide and the most important pathogenic factor of gastric cancer. The calculated ...
    • Iron deficiency on neuronal function 
      Muñoz, Pablo; Humeres, Alexis (2012)
      Because of the intrinsic ability of iron to catalyze the formation of reactive oxygen species, it has been associated with oxidative stress and neurodegenerative diseases. However, iron deficiency (ID) also negatively ...
    • Iron Mediates N-Methyl-D-aspartate Receptor-dependent Stimulation of Calcium-induced Pathways and Hippocampal ... 
      Muñoz, Pablo; Humeres, Alexis; Elgueta, Claudio; Kirkwood, Alfredo; Hidalgo Tapia, María Cecilia; Núñez González, Marco (AMER SOC BIOCHEMISTRY MOLECULAR BIOLOGY INC, 2011-04-15)
      Iron deficiency hinders hippocampus-dependent learning processes and impairs cognitive performance, but current knowledge on the molecular mechanisms underlying the unique role of iron in neuronal function is sparse. Here, ...
    • Recommendations of the chilean association for digestive endoscopy for the management of gastric pre-malignant ... 
      Rollán, Antonio; Cortés, Pablo; Calvo, Alfonso; Araya, Raúl; Bufadel, María Ester; González, Robinson; Heredia, Carolina; Muñoz, Pablo; Squella, Freddy; Nazal, Roberto; Gatica, María de Los Ángeles; Gobelet, Jaquelina; Estay, René; Pisano, Raúl; Contreras, Luis; Osorio Osorio, Francisco Antonio (Sociedad Medica de Santiago, 2014)
