Port-wine stain is a vascular malformation characterized pathologically by ectasia of superficial dermal capillaris and clinically by persistent macular erythema. The association of a port-wine stain on a limb with soft tissue swelling, with or without bony overgrowth, is termed klippel-Trenaunay syndrome. Phakomatosis pigmento-vascularis is a combination of port-wine stain and cutaneous ...

BACKGROUND An implantable port device provides an easily accessible central route for long-term chemotherapy. Venous catheter migration is one of the rare complications of venous port implantation. It can lead to side effects such as pain in the neck, shoulder, or ear, venous thrombosis, and even life-threatening neurologic problems. To date, there are few published studies that discuss such co...

the province of bushehr is located in southern area of iran and north of persian gulf. solid waste management in bushehr’s villages was the aim of this research. for the sake of this study, 21 villages scattered all over the province were selected. field studies showed that about 646 grams of residential solid waste per capita is generated in selected villages every day. there are 322 shops i...

The variable displacement pump control system has greater energy-saving advantages and application prospects than the valve control system. However, the variable displacement pump control of differential cylinder is not concurrent with the existing technologies. The asymmetric pump-controlled cylinder is, therefore, used to balance the unequal volume flow through a single rod cylinder in closed...

BACKGROUND The purpose of the current study was to evaluate whether a totally implanted valved subcutaneous port system would have fewer complications as compared to a standard nonvalved port. METHODS Study subjects requiring port placement were randomized to receive a valved port (PASV; Boston Scientific, Natick, MA) or a nonvalved port (BardPort; Bard Accesss Systems, Salt Lake City, UT). E...

This paper studies the comparison of two kinds of port regulation modes – the centralization mode and the decentralization mode – using principal-agent theory and dynamic game theory. The optimal tariffs, port capacities and port efficiency levels under these two regulation modes are determined. The theoretical results are applied to the container terminals in Port of Shanghai in China. Sensiti...

ions A first-order abstraction in the ρpg-calculus consists of two object port graphs for the leftand the right-hand sides, and an arrow node embedding the correspondence between the two sides. The arrow node has two particular ports, a handler port p0 and a black hole port bh. Some restrictions must be imposed on the connectivity of these two types of ports. A handler port can be connected onl...

Background In recent years, single-port video-assisted thoracoscopic surgery (VATS) for lobectomy in non-small cell lung cancer (NSCLC) patients has become increasingly common. The objective of this study was to compare the feasibility and safety of single-port and triple-port VATS lobectomy. Methods A total of 73 patients with NSCLC who underwent VATS lobectomy from December 2011 to August 2...
