Capsular-defective Porphyromonas gingivalis mutant strains induce less alveolar bone resorption than W50 wild-type strain due to a decreased Th1/Th17 immune response and less osteoclast activity
(Wiley-Blackwell, 2019)
Background: Encapsulation of Porphyromonas gingivalis has been demonstrated as responsible of several host immunological changes, which have been associated with the pathogenesis of periodontitis. Using a murine model of ...
Interleukin-35 inhibits alveolar bone resorption by modulating the Th17/Treg imbalance during periodontitis
(Wiley, 2020)
Aim T lymphocytes play a central role during the pathogenesis of periodontitis, and the imbalance between the pathogenic T-helper type 17 (Th17) and protective T-regulatory (Treg) lymphocytes determines the tooth-supporting ...
CCR2 Contributes to F4/80+ Cells Migration Along Intramembranous Bone Healing in Maxilla, but Its Deficiency Does Not Critically Affect the Healing Outcome
(Frontiers Media, 2018)
Bone healing depends of a transient inflammatory response, involving selective migration of leukocytes under the control of chemokine system. CCR2 has been regarded as an essential receptor for macrophage recruitment to ...
Alveolar bone resorption and TH1/TH17-associated immune response triggered during Aggregatibacter actinomycetemcomitans-induced experimental periodontitis are serotype-dependent
(Wiley-Blackwell, 2018)
BACKGROUND:
Aggregatibacter actinomycetemcomitans expresses several virulence factors that may contribute to the pathogenesis of periodontitis. Based on the antigenicity of the O-polysaccharide component of the ...
Inhibition of osteolysis and increase of bone formation after local administration of siRNA-targeting RANK in a polyethylene particle-induced osteolysis model
(Elsevier, 2015)
Receptor activator of nuclear factor kappa-B (RANK) and RANK-ligand are relevant targets for the treatment
of polyethylene particle-induced osteolysis. This study assessed the local administration of siRNA,
targeting ...
Estudio De Factibilidad En El Uso Del Microordenador Raspberry Pi 3 Modelo B Como Ordenador Para La Educación Básica En La Escuela Ciudad De Ariel Del Cantón Duran.
(Universidad de Guayaquil Facultad de Ciencias Matemáticas y Físicas Carrera de Ingeniería en Networking y Telecomunicaciones, 2018)
En los últimos años la tecnología avanzado a pasos agigantados, esto hace que países como el nuestro estemos atrasados en la educación tecnología, llegando al punto que las escuelas de educación básica de sectores urbanos ...
FILDIG: A program to filter brain electrical signals in the frequency domain
(2005)
A software program to filter brain electrical signals in the frequency domain has been developed and is presently reported. Many other filters are commercially available; however, most of them are linked to data acquisition ...

IL-22–expressing CD4+AhR+ T lymphocytes are associated with RANKL-mediated alveolar bone resorption during experimental periodontitis
(Wiley, 2019)
BACKGROUND AND OBJECTIVE: Over the past few years, the importance of interleukin-22 (IL-22) and T-helper (Th)22 lymphocytes in the pathogenesis of periodontitis has become apparent; however, there are still aspects that ...
Analysis of correlation between optical and microtomography measurements of cementation space in CAD-CAM ceramic crowns
(Elsevier B.V., 2020-07-01)
Statement of problem. Identical computer-aided design (CAD) parameters may be used to mill a variety of ceramic materials for computer-aided design and computer-aided manufacture (CADCAM) crowns. Whether milled crown spacing ...
