      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 ...
    • Endogenous residual claimancy by vertical hierarchies 
      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 ...
    • Endogenous thyroid-stimulating hormone and radioactive iodine uptake in normal subjects

    • Endogenous timing in duopolies 
      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 ...
    • Endoglin increases eNOS expression by modulating Smad2 protein levels and Smad2-dependent TGF-β signaling 
      Santibanez, Juan F.; Letamendia, Ainhoa; Perez-Barriocanal, Fernando; Silvestri, Cristoforo; Saura, Marta; Vary, Calvin P.H.; Lopez-Novoa, Jose M.; Attisano, Liliana; Bernabeu, Carmelo (2007)
      The endothelial nitric oxide synthase (eNOS) is a critical regulator of cardiovascular homeostasis, whose dysregulation leads to different vascular pathologies. Endoglin is a component of the transforming growth factor ...
    • Endoglin regulates cyclooxygenase-2 expression and activity 
      Jerkic, Mirjana; Rivas Elena, Juan V.; Santibáñez, Juan Francisco; Prieto, Marta; Rodríguez Barbero, Alicia; Pérez Barriocanal, Fernando; Pericacho, Miguel; Arévalo, Miguel; Vary, Calvin P.H.; Letarte, Michelle; Bernabeu, Carmelo; López Novoa, José M.
