AIMS: Type 2 diabetes (T2DM) is a recognized risk factor for intracranial stenosis (ICS) in China where ischemic stroke is a health priority. In Europe little information is available on T2DM prevalence among Chinese minority groups and vascular screening is commonly limited to extracranial vessels. Feasibility of community-based T2DM screening, differences in T2DM prevalence between Chinese migrants and Italians, and prevalence of ICS among Chinese patients with newly diagnosed T2DM were investigated...

PURPOSE: Preoperative discrimination between benign and malignant soft tissue tumors is critical for the prevention of excess application of magnetic resonance imaging and biopsy as well as unplanned resection. Although ultrasound, including power Doppler imaging, is an easy, noninvasive, and cost-effective modality for screening soft tissue tumors, few studies have investigated reliable discrimination between benign and malignant soft tissue tumors. METHODS: To establish a modality for discrimination between benign and malignant soft tissue tumors using ultrasound, we extracted the significant risk factors for malignancy based on ultrasound information from 40 malignant and 56 benign pathologically diagnosed soft tissue tumors and established a scoring system based on these risk factors...

Endothelial mechanotransduction is important for vascular function but alterations and activation of vascular mechanosensory proteins have not been investigated in humans. In endothelial cell culture, simple sugars effectively impair mechanosensor proteins. To study mechanosensor- and vascular function in humans, twelve young healthy male subjects supplemented their diet with 3 × 75 g sucrose day(-1) for 14 days in a randomized cross-over design. Before and after the intervention period, the hyperemic response to passive lower leg movement and active knee extensor exercise was determined by ultrasound doppler...

Electrospun polycaprolactone (PCL) vascular grafts showed good mechanical properties and patency. However, the slow degradation of PCL limited vascular regeneration in the graft. Polydioxanone (PDS) is a biodegradable polymer with high mechanical strength and moderate degradation rate in vivo. In this study, a small-diameter hybrid vascular graft was prepared by co-electrospinning PCL and PDS fibers. The incorporation of PDS improves mechanical properties, hydrophilicity of the hybrid grafts compared to PCL grafts...
