      Ferritin, a food constituent of animal and vegetal origin, is a source of dietary iron. Its hollow central cavity has the capacity to store up to 4,500 atoms of iron, so its potential as an iron donor is advantageous to ...
    • Pérez Henríquez, Patricio; Raikhel, Natasha V.; Norambuena Morales, Lorena (Oxford University Press, 2012)
      Plants' developmental plasticity plays a pivotal role in responding to environmental conditions. One of the most plastic plant organs is the root system. Different environmental stimuli such as nutrients and water deficiency ...
    • Núñez González, Marco; Gaete, Victoria; Escobar, Aldo (1990)
      Endocytic vesicles isolated from rabbit reticulocytes contained an intrinsic Ca2+-pump activity that was dependent on ATP, activated by calmodulin and inhibited by vanadate. 45Ca2+ uptake and acidification studies indicated ...

      Gossypol is a natural disesquiterpene that blocks the activity of the mammalian facilitative hexose transporter GLUT1. In human HL-60 cells, which express GLUT1, Chinese hamster ovary cells overexpressing GLUT1, and human ...
    • Danaf, Mazen; Guevara Cue, Cristian; Atasoy, Bilge; Ben-Akiva, Moshe (Elsevier, 2020)
      Endogeneity arises in discrete choice models due to several factors and results in inconsistent estimates of the model parameters. In adaptive choice contexts such as choice-based recommender systems and adaptive stated ...
    • Cea Echenique, Sebastián; Hervés Beloso, Carlos; Torres Martínez, Juan Pablo (Springer, 2017)
      We include endogenous differential information in a model with sequential trade and incomplete financial participation. Agents update information through market signals given by commodity prices and asset deliveries. ...
    • Cea Echenique, Sebastián; Torres Martínez, Juan Pablo (Universidad de Chile, Facultad de Economía y Negocios, 2010)
      We develop a two period general equilibrium model with incomplete financial markets and differential information. Making endogenous the traditional informational restriction on consumption, we allow agents to obtain ...
    • Villanueva,; Orrego, (1988)
      The presence in highly purified rat brain cortex synaptic vesicles of endogenous ligands for rat brain quisqualate receptors was investigated. The vesicles were extracted, and their contents fractionated by high voltage ...
    • Rojas, Diego A.; Urbina, Fabiola; Moreira Ramos, Sandra; Castillo, Christian; Kemmerling Weis, Ulrike; Lapier, Michel; Maya Arango, Juan; Solari Illescas, Aldo; Maldonado Maldonado, Edio (Public Library Science, 2018)
      Trypanosoma cruzi is exposed during its life to exogenous and endogenous oxidative stress, leading to damage of several macromolecules such as DNA. There are many DNA repair pathways in the nucleus and mitochondria ...
    • Piccolo, Salvatore; González Tissinetti, Aldo; Martina, Riccardo (Elsevier, 2014)
      In this note we study a model of vertical hierarchies where the allocation of residual claimancy is endogenous and is determined jointly with production and contractual decisions.Weshow that the (equilibrium) allocation ...
    • González, Patricio; Jaimovich, Rodrigo; Araya, Verónica; Massardo, Teresa; Carmona, Alberto (2012)
      In 105 normal volunteers, 52 male and 53 female, mean age 45 (range, 20-68), serum thyroid-stimulating hormone (TSH) (1.46 ± 0.7; range, 0.43-3.87 microUI/mL) and 24-hour thyroid radioactive iodine uptake (RAIU) (16.15% ± ...
    • Zúñiga Leyton, Eduardo Israel (Universidad de Chile, 2021)
      In this thesis we aim to understand how does leadership emerge in duopolistic competitions. In particular, we want to know which are the key features, of the firms and the market, that explain that some interactions are ...
