A mutation in LRP5 (low-density lipoprotein receptor-related protein 5) has been shown to increase bone mass and density in humans and animals. Transgenic mice expressing the LRP5 mutation (G171V) demonstrate an increase in bone mass as compared to non-transgenic (NTG) littermates. This study evaluated LRP5 gene and gender-related influences on the structural and biomechanical strength properti...

Juxtacanalicular (JXT) trabecular meshwork and endothelial lining of Schlemm's canal have been cited as the loci of aqueous outflow resistance, both in a normal as well as a glaucomatous eye. In this review, we attempt to understand the currently available surgical modalities in light of the available histopathological evidence, regarding localization of outflow resistance. How to cite this art...

Aims Prediction of trabecular fracture zone is a wide challenge not yet solved. Some in-vitro studies pointed out the importance of local variation of the framework for the global behavior of the whole trabecular structure [1-4]. Researchers agree that the identification of the weakest link in the trabecular framework can lead to the prediction of the fracture zone, first, and of the failure ev...

Trabecular bone structure has an important influence on bone strength, but little is known about its genetic regulation. To elucidate the genetic factor(s) regulating trabecular bone structure, we compared the trabecular bone structures of two genetically remote mouse strains, C57BL/6J and Japanese wild mouse-derived MSM/Ms. Phenotyping by X-ray micro-CT revealed that MSM/Ms has structurally mo...

PURPOSE To determine the effects of glucocorticoid treatment on the microfilament structure of cultured human trabecular meshwork cells. Topical or systemic administration of glucocorticoids can lead to the development of ocular hypertension and to the development of vision loss, which is clinically similar to primary open angle glaucoma. However, the mechanism(s) by which glucocorticoids cause...

The objective of this investigation is to analyze the influence of trabecular microstructure modeling on the biomechanical distribution of the implant-bone interface. Two three-dimensional finite element mandible models, one with trabecular microstructure (a refined model) and one with macrostructure (a simplified model), were built. The values of equivalent stress at the implant-bone interface...

Our previous study showed the early molecular responses of bone in response to obstructive nephropathy in a unilateral ureteral obstruction (UUO) mouse model. Here, we addressed the changes in trabecular bone properties at greater trochanter, the proximal and the distal metaphysis of femur in UUO mice. The male mice were subjected to UUO (n=10) or sham operation (n=10). All mice were killed on ...

this study was conducted to investigate the correlation between lipid-lowering and bone-protective effects of eicosapentaenoic acid on steroid-induced bonechanges in rats. twenty-one male 10-week-old wistar rats were divided into 3 groups (n = 7 each) and treated with 0.9% nacl sc (group 1) or methylprednisolone 7 mg/kg sc once a week (group 2) or methylprednisolone 7 mg/kg sc once a week + eic...
