Associations between bone mineral density and subclinical atherosclerosis: a cross-sectional study of a Chinese population.

Context: The significance of associations between bone mineral density (BMD) and atherosclerosis in the Asian population is less clear.

Objective: The aim of this study was to explore the population-level associations between BMD and subclinical atherosclerosis.

Design And Setting: This was a community-based cross-sectional study conducted in Shenyang, China.

Analysis of the transient expansion behavior and design optimization of coronary stents by finite element method.

The percutaneous transluminal coronary angioplasty (PTCA) assisted with stenting technique has become a primary therapy to coronary heart disease. In practice, the structure conditions of both ends of stent/balloon system influence a stent's instantaneous expansion behavior. The transitory nonuniform expansion, the so-called dogboning, of stent/balloon system is one of the main reasons to induce the acute vascular injury at the two edges of a stent.

[The influence of the screw thread and the height of constraints on the stress distribution around dental implants by using three-dimensional finite element analysis].

Objective: To study the influence of the screw thread and the height of constraints on the stress distribution of the implants.

Methods: The three-dimensional emulational models of the implants with different screw-pitch were constructed by a CAD/CAM package. The Von Mises stress of the models was analyzed by three-dimensional finite element method.
