Does human cytomegalovirus infection impair endothelial cell chemotaxis by disturbing VEGF signalling and actin polymerization?
We demonstrated a significant reduction of the chemotactic mobility of HCMV-infected HCAEC mediated by down-modulation of the VEGFR-2 and by inhibition of actin polymerization. This VEGF resistance of HCMV-infected endothelial cells is likely to promote atherogenesis.
The Perclose suture-mediated closure device is efficacious and can be used safely in selected patients with documented peripheral vascular disease. Complications associated with this device tend to be more severe than those historically reported for manual compression. Substantial experience with use of this device is required to achieve excellent results in patients with difficult anatomy.
