AIM To evaluate the importance of surgical bypass between the terminal part of functional arteriovenous shunt (av) for hemodialysis on upper extremity and inner jugular vein in axillosubclavian venous segment obstruction associated with central venous hypertension. METHOD Retrospective assessment of surgical bypass between central segments of av fistula and ipsilateral/contralateral inner jug...

We present in this paper a case of cardiac herniation following right intrapericardial pneumonectomy after induction chemotherapy. A 52-year-old man with advanced squamous cell carcinoma of the lung was admitted to our hospital suffering from a dry cough and chest pain. An intrapericardial pneumonectomy with partial pericardiectomy (4 x 4 cm) was performed. The pericardial defect was left open....

In vivo self-endothelialization by endothelial cell adhesion on cardiovascular implants is highly desirable. DNA-oligonucleotides are an intriguing coating material with nonimmunogenic characteristics and the feasibility of easy and rapid chemical fabrication. The objective of this study was the creation of cell adhesive DNA-oligonucleotide coatings on vascular implant surfaces. DNA-oligonucleo...

The development of polymer electrolyte membrane (PEM) fuel cells that can be operated over a wide temperature range without the need for humidification is highly desirable for vehicle applications to overcome the problems associated with CO poisoning and water management. Here we report a novel PEM based on 1H-1,2,4-triazole grafted polysiloxane doped with phosphoric acid and reinforced with po...

Gore-Tex, a form of expanded polytetrafluoroethylene (ePTFE), over the past 30 years has attracted much attention as an alloplast for use in rhinoplasty, both from advocates and opponents of its use. It has many desirable traits as an alloplast implant, but many surgeons harbor hesitation and reluctance for alloplast use in rhinoplasty based on historical data of previous nasal implants. Only w...
