tissue microscopic geometry affects spread cancer
2021/3/26
Oregon State University research has revealed a crucial mechanism behind one of humankind's most deadly physiological processes: the movement of malignant cells from one part of the body to another.Pu...
Signaling Pathways Involved in Mechanical Stimulation and ECM Geometry in Bone Cells
Mechanical Stimulation Osteoblast ECM
2015/1/12
The proliferation and differentiation of osteoblasts are influenced by mechanical and geometrical growth environments. A specific aim of my thesis was the elucidation of signaling pathways involved in...
Precision Geometry Scaffolding using MEMS Technology
Geometry Scaffolding MEMS Technology polysilicon
2009/12/23
Enabled by MEMS (semiconductor-based) technology, our group has produced a chainmail-based
tissue scaffold out of polysilicon. We constructed the tissue scaffold through the combination of
photolith...
The moments and forces produced by various orthodontic T-loop spring designs were measured. The effects of dimension changes (within clinically used ranges) and the addition of gable bends with he...

Background: The principal aim of this study was therefore to investigate association between family history of osteo¬porotic hip fracture, BMD and femur geometry in Bushehr city in South of Iran. ...
Vertebral Geometry Parameters Can Predict Fractures
Vertebral geometry Fracture BMD Radiography
2010/4/8
Background: The aim of this study was to investigate vertebral geometry changes and determine cutoff value of vertebral height to predict fractures. Methods: In a cross-sectional study, 280 postmenopa...
Calculation of arterial wall temperature in atherosclerotic arteries: effect of pulsatile flow, arterial geometry, and plaque structure
arterial wall temperature atherosclerotic arteries pulsatile flow arterial geometry plaque structure
2010/2/26
The results indicate that direct temperature measurements should be taken (1) as close as possible to the plaque/lumen surface, as the calculations show a significant drop in temperature within 120 mi...
Alterations in regional vascular geometry produced by theoretical stent implantation influence distributions of wall shear stress: analysis of a curved coronary artery using 3D computational fluid dynamics modeling
regional vascular geometry theoretical stent implantation a curved coronary artery 3D computational fluid dynamics modeling
2010/2/26
The current results predicting large spatial and temporal variations in WSS at specific locations in curved arterial 3D CFD simulations are consistent with clinically observed sites of restenosis. If ...
