A Computational Model of the Ocular Lens
… model of the structure and function of the ocular lens, specifically the solute and fluid transport in the lens. The modelling framework was based on finite volume methods. The intracellular and extracellular solute fluxes were modelled using the Nernst-Plank equation with an extra term to …

Potential roles for transforming growth factor-B during terminal differentiation of ocular lens cells /
During terminal differentiation, lens fiber cells permanently withdraw from the cell cycle, migrate posteriorly along the lens capsule, become greatly elongated and eliminate all cellular organelles. Lens fiber differentiation may be controlled by various factors within the ocular environment. The …

Genetic analyses of the Rb and p53 genes in murine development and tumorigenesis
… (CNS), peripheral nervous system (PNS), and ocular lens. Loss of p53 can prevent the apoptosis in the CNS and lens; however, the specific signals leading to p53 activation have not been determined. We tested the hypothesis that hypoxia caused by defective erythropoiesis in Rb-null embryos …

Improving hydrophilicity of silicone elastomer by IPN formation with hyaluronan
Soft contact lenses have been available to consumers for the past several decades. By far, the most popular form on the market today is the silicone hydrogel, with nearly 70% of the market share. However, many contact lens wearers still have issues which cause them to discontinue lens use. It is …

Ray Tracing Confirms the Optical Properties of the Bovine Lens Are Actively Maintained by the Microcirculation System
Ocular pathologies such as cataract have become increasingly common as the human population continues to age due to better healthcare. As such, the need for an improved understanding of the underlying causes is necessary. Using a variety of Magnetic Resonance Imaging (MRI) modalities and optical …

Correlación entre el resultado refractivo post-catarata con la predicción biométrica pre-operatoria
La cirugía de cataratas por Facoemulsificación es tal vez uno de los procedimientos más realizados en la práctica de oftalmología general, sin embargo el resultado refractivo de esta cirugía no siempre llena las expectativas del oftalmólogo y del paciente, es por esto que es de gran importancia …
