In recent years, endothelial progenitor cells (EPCs) have been demonstrated to play an important role during tissue vascularization and endothelium homeostasis in adults. In addition, EPCs have been implicated in the pathophysiology of cardiovascular and cerebrovascular disease, such that a decreased number of EPCs may not only be a risk indicator but also(More)
BACKGROUND Robot-assisted anastomosis holds great promise for the future. To secure surgery quality, some key process factors, such as the force arrangement of sutures, should be provided because of the lack of haptic feedback in robotics systems METHODS A model of anastomosis is presented to establish the mechanical relationship between vessel and(More)
Endothelial progenitor cells (EPCs) repair vascular damage and participate in neovascularization. Accumulating evidence has demonstrated that EPCs have therapeutic potential in reactive oxygen species (ROS)-mediated vascular diseases. In this study, to investigate the effects of oxidative stress on EPCs, EPCs were treated with H2O2 at different final(More)
Hemming is a three-step sheet-folding process utilized in the production of automotive closures. It has a critical impact on the performance and perceived quality of assembled vehicles. Using a two-dimensional finite element model, this paper presents a design-of-experiments (DOE) study of the relationships between important hemming process parameters and(More)
Eighteen patients with arteriovenous malformations (AVMs) of the brain were treated with endovascular techniques between 1993 and 1996. The following angiograms showed complete obliteration of the nidus in 2 patients, 70%-90% reduction in nidus volume in 5, 50%-70% reduction in 3, and < 50% in the remaining 3. Two patients suffered from moderate neurologic(More)
BACKGROUND Due to differences in surgical operations between free-hand and robot-assisted vessel anastomosis, there exist new challenges in applying the manipulation criteria of free-hand surgery to robot-assisted surgery in order to guarantee successful completion of the surgical procedure. METHODS A mathematical model is established to optimize the(More)
