Experiments have been done to determine the time in the development of the embryonic chick limb when the cells in the cartilage-forming area become "stabilized." The particular criterion for stability used in this work was the ability of the cells to resist the infiuences in the limb which cause some limb mesenchyme cells to form cartilage and other limb mesenchyme cells to form soft tissue. Bl...
A glutaraldehyde preserved valved bovine jugular xenograft mounted in a nitinol 'Z' stent, expandable from 7 to 28 mm of internal diameter, was evaluated in vitro (column of water developing a pressure of 45 mmHg and a mock loop including a pulsatile pump) and in vivo in five adult pigs with intra-vascular ultrasound to measure the inferior vena cava diameter via a retroperitoneal access. Throu...
PURPOSE To explore the phonological awareness skills of deaf children with cochlear implants (CIs) and relationships with vocabulary and reading development. METHOD Forty-three deaf children with implants who were between 5 and 15 years of age were tested; 21 had been implanted at around 2.5 years of age (Early CI group), and 22 had been implanted at around 5 years of age (Late CI group). Two...
BACKGROUND The role of totally implantable central venous port (TICVP) system is increasing. Implantation performed by radiologist with ultrasound-guided access of vein and fluoroscope-guided positioning of catheter is widely accepted nowadays. In this article, we summarized our experience of TICVP system by surgeon and present the success and complication rate of this surgical method. MATERI...
Implantable ports are used for intravenous infusion therapy and play an important role in management of oncology patients. These ports are best suited for patients requiring long-term therapy (>4 weeks). Implanted ports provide reliable venous access protect peripheral access increase patients’ comfort through reducing repeated and difficult vein punctures allow for safe and comfortable admi...
BACKGROUND Restenosis has been reported in as many as 50% of patients within 6 months after PTCA in acute myocardial infarction (AMI), which necessitates repeat target-vessel revascularization (TVR) in approximately 20% of patients during this time period. Routine (primary) stent implantation after PTCA has the potential to further improve late outcomes. METHODS AND RESULTS Primary stenting w...
