The artificial vascular grafts currently in clinical use still have problems with respect to late calcification, restenosis, antithrombotic property, durability, biocompatibility, and safety, and no ideal artificial vascular graft has been developed to date. In view of this, we have been continuing basic experimental studies and their clinical applications in an attempt to develop tissue-engine...

See related article, pages 3145–3151. The relation between migraine and stroke has been well recognized and has been the focus of several publications.1–3 Despite many hypotheses linking the 2 disorders, the precise mechanisms are unknown, and not surprisingly very complex.

distribution of retinal blood vessels (rbvs) in retinal images has an important role in the prevention, diagnosis, monitoring and treatment of diseases, such as diabetes, high blood pressure, or heart disease. therefore, detection of the exact location of rbvs is very important for ophthalmologists. one of the frequently used techniques for extraction of these vessels is region growing-based se...

Background: New blood vessels formation is a critical step in tumor progression. Vascular density affects the clinical outcome and prognosis of malignant tumors. The aim of this study was to investigate the relation between the Vascular Endothelial Growth Factor (VEGF) expression and vascular density with the clinical and histopathologic features in oral squamous cell carcinoma (OSCC). &nbsp...
