R.; Williams, T.; Sturch, C.; Baganoff, F. K.; Chaboyer, Brian; Schommer, R. A.; Tirado, H.; Hernández, M.; Ugarte, P.; Guhathakurta, P.; Howell, S. B.; Szkody, P.; Schmidtke, P. C.; Roth, J. (AMER INST PHYSICS, 1993-12)
      We have started a search for supernovae as a collaboration between the University of Chile and the Cerro Tololo Inter-American Observatory, with the aim of producing a moderately distant (0.01 < z < 0.10) sample of Type ...
    • Association of Endodontic Lesions with Coronary Artery Disease 

      Liljestrand, J. M.; Mantyla, P.; Paju, S.; Buhlin, K.; Kopra, K. A. E.; Persson, G. R.; Hernández, M.; Nieminen, M. S.; Sinisalo, J.; Tjaderhane, L.; Pussinen, P. J. (SAGE, 2016)
      An endodontic lesion (EL) is a common manifestation of endodontic infection where Porphyromonas endodontalis is frequently encountered. EL may associate with increased risk for coronary artery disease (CAD) via similar ...
    • Bone resorptive activity in symptomatic and asymptomatic apical lesions of endodontic origin 

      Salinas Muñoz, M.; Garrido Flores, Carlos; Baeza Paredes, Mauricio; Huaman Chipana, P.; García Sesnich, Jocelyn; Bologna, R.; Vernal Astudillo, Rolando; Hernández, M. (Springer, 2017)
      The aim of this study is to assess the levels and diagnostic accuracy of a set of bone resorption biomarkers, including TRAP-5, RANKL, and OPG in symptomatic and asymptomatic apical lesions and controls. Apical tissues ...
    • Differential response of dendritic cells upon co-infection with different Aggregatibacter actinomycetemcomitans serotypes 

      Rojas, L.; Álvarez, C.; Melgar Rodríguez, Samanta Azucena; Pujol, M.; Monasterio, G.; García, K.; Díaz Zúñiga, J.; Fariña, V.; Hernández, M.; Vernal Astudillo, Rolando (2016)
    • H2O2 activates matrix metalloproteinases through the nuclear factor kappa B pathway and Ca2+ signals in human periodontal fibroblasts 

      Osorio, C.; Cavalla, F.; Paula Lima, Andrea; Díaz Araya, Guillermo; Vernal Astudillo, Rolando; Ahumada, P.; Gamonal Aravena, Jorge Antonio; Hernández, M. (Wiley & Sons, 2015)
      BackgroundThe mechanisms involved in reactive oxygen species and matrix metalloproteinase (MMP)-mediated periodontal tissue breakdown are unknown. ObjectiveTo determine the effect of H2O2 in MMP-2 and MMP-9 activity, ...
    • Human periodontal ligament fibroblasts synthesize C-reactive protein and Th-related cytokines in response to interleukin (IL)-6 trans-signalling 

      Hernández Caldera, Arnoldo; Vernal Astudillo, Rolando; Paredes, R.; Veloso Matta, Pietro; Astorga, J.; Hernández, M. (Blackwell Publishing Ltd, 2018)
      © 2017 International Endodontic Journal. Published by John Wiley & Sons LtdAim: To characterize the potential of human periodontal ligament fibroblasts (HPLF) to synthesize CRP and Th-related cytokines in response to IL-6 ...
    • Incidence of myocarditis in patients with dilated cardiomyopathy 

      Kauffmann,; Arellano, L.; Hernández, M.; Florenzano, F.; Donoso, S. (1990)
      We performed right ventricular endomyocardial biopsies in 23 patients with dilated cardiomyopathy aged 45 +/- 14 years. All patients had congestive heart failure of unknown etiology dating up to one year before the procedure ...
    • Large-scale stationary convection in a cylindrical current-carrying plasma 

      Gomberoff, L.; Hernández, M. (1984)
      Nonideal effects such as viscosity and thermal conductivity on the stability of a cylindrical current‐carrying plasma in a shearless magnetic field are studied. It is shown that for magnetic fields satisfying Bθ/Bz ≫1, ...
    • Ovarian Morphology and Serum IGF-I Levels in Postmenarcheal Hyperandrogenic Oligomenorrheic Girls 

      Hernández, M.; Gaete, X.; López P., Sandra; Ávila, A.; Villarroel Quintana, Claudio; Jesam Gaete, Cristian; Iñíguez Vila, Germán; Cassorla Goluboff, Fernando; Merino Osorio, Paulina (Karger, 2015)
    • Reduced Humanin Levels in Children with Type-1 Diabetes Mellitus 

      Hernández, M.; Wan, J.; Valdés, C.; Ávila, A.; Codner Dujovne, Ethel; Cohen, P. (Karger, 2015)
    • Stationary convection in a cylindrical plasma 

      Gomberoff, L.; Hernández, M. (1983)
      It is shown that viscosity and thermal conductivity leads to large-scale steady convection in a cylindrical current-carrying plasma, under the influence of a magnetic field satisfying (BθBz)&gt;&gt;1. This state is the ...
