Selenium Effects on the Trabecular Meshwork
… the effects of selenium on the conventional "trabecular" aqueous outflow pathway, a likely site of pathology for glaucoma. Human trabecular meshwork (HTM) cells and human umbilical vein endothelial cells (HUVECs) were treated with selenium (MSeA) at or near physiologically relevant …

Microdamage accumulation in bovine trabecular bone
… and quantify microdamage in specimens of bovine trabecular bone damaged in uniaxial compression and compressive fatigue, and relationships between microdamage parameters and changes in mechanical properties (maximum compressive strain, modulus reduction) were quantified.

Trabecular Calcium Phosphate Scaffolds for Bone Regeneration
… matched to the local architecture of natural trabecular bone and to apply tissue engineering strategies for the study of cell behavior in both in vitro and in vivo models.The specific role of environment on cell stress pathways was evaluated on three dimensional (3-D) calcium phosphate …

Modeling trabecular microstructure evolution via genetic algorithm
… selection generated was the ability of trabecular bone to optimize and adjust its structure in vivo in response to changes in its loading conditions. This work presents a model for trabecular microstructure evolution using a genetic algorithm, the same mechanism through which that …

Phenotypic Characterization of Segmental Human Trabecular Meshwork Cells
… Aqueous humor outflow is segmental in the trabecular meshwork (TM) with regions of high-flow (HF) or low-flow (LF) that vary in molecular signature, biomechanics, and response to pressure in both normal and glaucoma eyes. We sought to investigate whether cells in these regions (1) deposit …

Material Differences in Equine Cortical and Trabecular Bone
… study set out to determine whether cortical and trabecular bone are two separate materials, or whether they are the same material with a variance in porosity. To answer this question, samples were taken from different sections of the equine metacarpus, underwent densitometry analysis and were …

The Relationship of Trabecular Meshwork Stiffness and Outflow Function
<p>The trabecular meshwork (TM) is comparable to a bioactive filter that plays a major role in regulating outflow of aqueous humor of the eye and setting intraocular pressure (IOP). TM dysfunction may lead to ocular hypertension which is the major risk factor in glaucoma. Although the outflow …

Structural and functional investigation of the trabecular outflow pathway
… of studies which investigated structures of the trabecular outflow pathway, including Schlemm’s canal endothelium, juxtacanalicular tissue, and trabecular beams, and their roles in regulating aqueous outflow resistance. The studies were conducted in both human and animal models using ex vivo …

Trabecular topology : computational structural design inspired by bone remodeling
… It also gives a special topology to the trabecular bone. This thesis proposes a new computational structural design approach inspired by the trabecular bone topology and remodeling process and it can be applied to the 2D, 3D and building-scale structures. It reveals the importance of the …

Analysis of trabecular bone mechanical properties from magnetic resonance images
… (3D) images for the morphological analysis of trabecular bone. Furthermore, the 3D image data can be the source of finite element (FE) models. FE analysis of such data represents a means to assess the mechanical response virtually. Whole-body CT and MRI scanners are able to provide …

Ontogeny and functional adaptation of trabecular bone in the human foot
Trabecular bone forms the internal scaffolding of most bones, and consists of a microscopic lattice-like structure of interconnected bony struts. Experimental work has demonstrated that trabecular bone adapts its structural rigidity and orientation in response to the strains placed upon the …

On the rate-dependent constitutive response of cortical and trabecular bone
… major constituents of the skull: cortical and trabecular bone. The mechanical behavior of these two materials over a wide range of strain rates is identified through both a review of the existing literature data and our own experimental investigations. For the behavior of compact bone two …
