Shear stress is often present in the blood flow within blood-contacting devices, which is the leading cause of hemolysis. However, the simulation method for blood flow with shear stress is still not ...

In human coronary arteries, atherosclerotic plaques tend to spread downstream because of the changes in blood flow patterns the plaque causes, researchers have found. This insight comes from a study ...

“Clot-busting” fibrinolytic drugs are administered to patients who have had a heart attack or ischemic stroke. These drugs are delivered systemically or, when possible, locally through a catheter ...

The two main blood flow patterns, namely, pulsatile shear (PS) prevalent in straight segments of arteries and oscillatory shear (OS) observed at branch points, are associated with atheroprotective ...

Cardiovascular disease, the leading global cause of death, is precipitated by endothelial cell (EC) dysfunction. When EC are exposed to unidirectional steady laminar flow (>12 dynes/cm2 shear stress), ...

Dutch researchers report that in mice, different types of shear stress induce the production of different soluble factors known as chemokines, and that the chemokine expression pattern influences the ...

Dilatants are a class of non-Newtonian fluids characterized by their ability to transition from a fluid state to a near-solid state under shear stress due to a high concentration of solid particles ...

Rheometry is the method used to analyze the rheological behavior of a material; with rheology defined as the study of matter when it flows or is deformed. As a result rheology describes forces and ...

Jointing is a basic function of engineering. For example, bolting two parts together can involve material properties and loading forces. Here, we will focus on preloading, shear and tear-out in a ...
