Journal ArticleDOI
Induction of COX-2 and PGE2 biosynthesis by IL-1β is mediated by PKC and mitogen-activated protein kinases in murine astrocytes
TL;DR: Key roles for PKC as well as for ERK1/2 and p38 MAP kinase cascades in the biosynthesis of PGE2 are suggested by regulating the induction of cyclo‐oxygenase‐2, in IL‐1β‐stimulated astroglial cells.
Journal ArticleDOI
Optical distortion correction in Optical Coherence Tomography for quantitative ocular anterior segment by three-dimensional imaging
Sergio Ortiz,Damian Siedlecki,Ireneusz Grulkowski,Laura Remón,Daniel Pascual,Maciej Wojtkowski,Susana Marcos +6 more
TL;DR: The application of 3-D optical distortion correction increased significantly both the accuracy of the radius of curvature estimates and particularly asphericity of the surfaces, with respect to conventional methods of OCT image analysis.
Journal ArticleDOI
Optical coherence tomography for quantitative surface topography
TL;DR: Computer simulations allowed us to quantify the effect and evaluate its dependence on the scanning mirror separation and design of the collimating lens, as well as to estimate the optimal axial position of that lens to minimize the fan distortion.
Journal ArticleDOI
Three-dimensional reconstruction of the crystalline lens gradient index distribution from OCT imaging.
TL;DR: An optimization method to retrieve the gradient index (GRIN) distribution of the in-vitro crystalline lens from optical path difference data extracted from OCT images and found a refractive index ranging from 1.362 in the surface to 1.443 in the nucleus of the lens.
Journal ArticleDOI
Corneal topography from spectral optical coherence tomography (sOCT)
Sergio Ortiz,Damian Siedlecki,Pablo Pérez-Merino,Noelia Chia,Alberto de Castro,Maciej Szkulmowski,Maciej Wojtkowski,Susana Marcos +7 more
TL;DR: A Bland-Altman analysis showed consistent differences in the estimated asphericity and corneal shape between sOCT topographies without fan distortion correction and the rest of the measurements.
