High-level and longer-term activity recognition has great potentials in areas such as medical diagnosis and human behavior modeling. So far however, activity recognition research has mostly focused on low-level and short-term activities. This paper therefore makes a first step towards recognition of high-level activities as they occur in daily life. For(More)
OBJECTIVE To report the long-term results of our experience using cerebrospinal fluid drainage and distal aortic perfusion in descending thoracic and thoracoabdominal aortic repair. SUMMARY BACKGROUND DATA Repair of thoracoabdominal and thoracic aortic aneurysm by the traditional clamp-and-go technique results in a massive ischemic insult to several major(More)
BACKGROUND Neurologic deficit (paraparesis and paraplegia) after repair of the thoracic and thoracoabdominal aorta remains a devastating complication. The purpose of this study was to determine the effect of cerebrospinal fluid drainage and distal aortic perfusion upon neurologic outcome during repair of thoracic and thoracoabdominal aortic aneurysm (TAAA)(More)
The manual assessment of activities of daily living (ADLs) is a fundamental problem in elderly care. The use of miniature sensors placed in the environment or worn by a person has great potential in effective and unobtrusive long term monitoring and recognition of ADLs. This paper presents an effective and unobtrusive activity recognition system based on(More)
BACKGROUND The benefit of distal aortic perfusion and cerebrospinal fluid drainage over the "clamp and sew" technique during repairs of the descending thoracic aorta is still being debated. The purpose of this report is to analyze our experience with regard to neurologic deficit (paraplegia and paraparesis) and mortality using the adjuncts of distal aortic(More)
PURPOSE Hemodynamic alterations have been implicated as major stimuli for the development of intimal hyperplasia in vein grafts that are implanted in the arterial circulation. Tyrosine kinase is known to mediate cell signaling. However, its role with in vivo mechanotransduction is not yet well defined. We used a novel bioprosthetic collagen tube to provide(More)
BACKGROUND Although the incidence of patients presenting with concomitant colorectal cancer (CRC) and abdominal aortic aneurysm (AAA) is low, current treatment strategies in patients with both lesions remains controversial. Given recent advances in endovascular aortic aneurysm repair (EVAR), we sought to analyze the surgical outcomes of patients with(More)
BACKGROUND Neurologic deficit (paraplegia or paraparesis) remains a significant morbidity in the repair of descending thoracic aortic aneurysm. METHODS Between February 1991 and February 2000, we operated on 182 patients for descending thoracic aortic aneurysm. For the purpose of this study-to identify the impact of the combined adjuncts distal aortic(More)
BACKGROUND Intimal hyperplasia is due to the migration and proliferation of vascular smooth muscle cells after bypass surgery. Tyrosine kinases are involved in many signal transduction pathways including cell proliferation. This study examines the effects of local treatment with the tyrosine kinase inhibitor, tyrphostin AG-51, on the formation of intimal(More)
