    • Biomimetic, Mild Chemical Synthesis of CdTe-GSH Quantum Dots with Improved Biocompatibility 
      Pérez Donoso, José; Monrás, Juan P.; Bravo, Denisse; Aguirre, Adam; Quest, Andrew F. G.; Osorio Román, Igor; Aroca, Ricardo F.; Chasteen, Thomas G.; Vásquez, Claudio C. (2012)
      Multiple applications of nanotechnology, especially those involving highly fluorescent nanoparticles (NPs) or quantum dots (QDs) have stimulated the research to develop simple, rapid and environmentally friendly protocols ...
    • Different sugar residues of the lipopolysaccharide outer core are required for early interactions of ... 
      Bravo, Denisse; Hoare, Anilei; Silipo, Alba; Valenzuela, Camila; Salinas, Catalina; Álvarez Armijo, Sergio Aníbal; Molinaro, Antonio; Valvano, Miguel A.; Contreras, Inés (Elsevier, 2011)
      The role of lipopolysaccharide (LPS) in entry of Salmonella Typhimurium into epithelial cells remains unclear. In this study, we tested the ability of a series of mutants with deletions in genes for the synthesis and ...
    • Enhanced caveolin-1 expression increases migration, anchorage-independent growth and invasion of endometrial ... 
      Díaz Valdivia, Natalia; Bravo, Denisse; Huerta, Hernán; Henríquez, Soledad; Gabler Neale, Fernando; Vega Blanco, María Margarita; Romero Osses, Carmen; Calderón, Claudia; Owen, Gareth I.; Leyton Campos, Lisette; Quest, Andrew F. G. (BioMed Central, 2015)
      Background: Caveolin-1 (CAV1) has been implicated both in tumor suppression and progression, whereby the specific role appears to be context dependent. Endometrial cancer is one of the most common malignancies of the female ...
    • Host response mechanisms in periodontal diseases 
      Silva, Nora; Abusleme Ramos, Loreto Andrea; Bravo, Denisse; Dutzan Muñoz, Nicolás; García Sesnich, Jocelyn; Vernal Astudillo, Rolando; Hernández, Marcela; Gamonal Aravena, Jorge Antonio (Univ Sao Paulo Fac Odontologia Bauru, 2015)
      Periodontal diseases usually refer to common inflammatory disorders known as gingivitis and periodontitis, which are caused by a pathogenic microbiota in the subgingival biofilm, including Porphyromonas gingivalis, ...
    • Microarray analysis of the Escherichia coli response to CdTe-GSH Quantum Dots: Understanding the bacterial ... 
      Monrás, Juan P.; Collao, Bernardo; Molina Quiroz, Roberto C.; Pradenas, Gonzalo A.; Saona, Luis A.; Durán Toro, Vicente; Órdenes Aenishanslins, Nicolás; Venegas, Felipe A.; Loyola, David E.; Bravo, Denisse; Calderón, Paulina F.; Calderón, Iván L.; Vásquez, Claudio C.; Chasteen, Thomas G.; López, Desiré A.; Pérez Donoso, José M. (BioMed Central, 2014)
      Background: Most semiconductor nanoparticles used in biomedical applications are made of heavy metals and involve synthetic methods that require organic solvents and high temperatures. This issue makes the development of ...
    • The outer core lipopolysaccharide of Salmonella enterica Serovar typhi is required for bacterial entry into ... 
      Hoare, Anilei; Bittner, Mauricio; Carter, Javier; Álvarez Armijo, Sergio Aníbal; Zaldívar San Román, María Mercedes; Bravo, Denisse; Valvano, Miguel A.; Contreras, Inés (AMER SOC MICROBIOLOGY, 2006-03)
      Salmonella enterica serovar Typhi causes typhoid fever in humans. Central to the pathogenicity of serovar Typhi is its capacity to invade intestinal epithelial cells. The role of lipopolysaccharide (LPS) in the invasion ...
    • Porphyromonas gingivalis-Helicobacter pylori coincubation enhances Porphyromonas gingivalis virulence and ... 
      Soto Mendoza, Cristopher; Rojas, Victoria; Yáñez, Lucas; Hidalgo, Antonio; Olivera, Marcela; Pacheco, Martín; Venegas Díaz, Darna Angelina; Salinas, Daniela; Bravo, Denisse; Quest, Andrew Frederick Geoffery (Taylor & Francis, 2022)
      Background: Porphyromonas gingivalis is part of the subgingival biofilm and a keystone species in the development of periodontitis. Interactions between P.gingivalis and other bacteria in biofilms have been shown to ...
