The aim of this study was to evaluate the significance of using multi-row spiral computed tomography (CT) to scan for pulmonary artery thrombosis and lower limb deep vein thrombosis (LVT) in patients with suspected LVT. A total of 110 patients underwent a contrast-enhanced spiral CT inspection of the pulmonary artery and lower extremity veins. Three-dimensional digital image processing, includi...

Extravillous trophoblasts invade the uterine wall (interstitial invasion) and the spiral arteries (endovascular invasion), replacing the cells of the vessel wall and creating a high-flow low-resistance vessel. We have developed a novel model to allow the interactions between the invading trophoblast cells and the cells of the spiral artery to be directly examined. Unmodified (non-placental bed)...

Haemochorial placentation, as it occurs in the human and other primate and rodent species, requires a connection of the placenta with supplying maternal (uteroplacental) arteries. Very little is known of the initial stages but endovascular trophoblast invasion seems to represent an essential element for further elaboration of an adequate uteroplacental circulation. In the human, endovascular tr...

STUDY QUESTION Are alterations in decidual expression of interleukin (IL)-6 and IL-8 associated with sporadic miscarriage? SUMMARY ANSWER IL-6 and IL-8 secretion from decidual uterine natural killer (uNK) cells and macrophages isolated from women with spontaneous miscarriage was reduced compared with normal controls. WHAT IS KNOWN ALREADY Miscarriage is a common gynaecological problem with ...

Spiral and non-spiral blood flows through three-dimensional models of 75% axisymmetric arterial stenosis are investigated by using two-equation standard k-ω transitional model and Large Eddy Simulation (LES). The arterial stenosis models chosen are straight stenosed tubes without and with upstream curved segments of various angles of curvature. The Reynolds numbers investigated are 500, 1000, 1...

A spiral high-resolution coronary artery imaging sequence (SH) interfaced with real-time localization system (RT) has been developed. A clinical study of 40 patients suspected of coronary artery disease (CAD) was conducted. Segmented k-space acquisition techniques have dominated magnetic resonance coronary angiography (MRCA) over the last decade. Although a recent multicenter trial using this t...

Tortuosity in coronary artery has been found to be greatly related the potential sites of stenosis these last years. Many investigations have carried out based on tool Computational Fluid Dynamics (CFD) mainly focusing influences curved blood flow. Within limited coupling between and tortuosity, considered located at tortuous segment. However, with recent clinical studies, case occurred non-tor...
