Abdominal aortic aneurysms (AAAs) represent a focal dilation of the aorta exceeding 1.5 times its normal diameter. It is reported that 4-8% of men and 0.5-1% of women above 50 years of age bear an AAA. Rupture represents the most disastrous complication of aneurysmal disease that is accompanied by an overall mortality of 80%. Autopsy data have shown that nearly 13% of AAAs with a maximum diamet...
BACKGROUND Epidemiological studies show that an unfavorable lipid profile and coronary artery disease (CAD) are risk traits for abdominal aortic aneurysms (AAAs) but not for intracranial aneurysms (IAs), and that hypertension is a main risk trait for IAs but not for AAAs. To evaluate these observations, we investigated single-nucleotide polymorphisms associated with serum lipid levels, hyperten...

The state of science education in the United States has been targeted for special attention by the AAAS Board of Directors. Both the Board and the AAAS Council passed resolutions calling for a reverse in the decline of science education in this country. In addition, the theme for the 1982 Annual Meeting will be "Toward a National Commitment of Education Excellence in Science and Engineering for...
This paper introduces research within the ALADIN project, which aims to develop an assistive vocal interface for people with a physical impairment. In contrast to existing approaches, the vocal interface is self-learning, which means it can be used with any language, dialect, vocabulary and grammar. This paper describes the overall learning framework, and the two components that will provide vo...
Background The incidence of abdominal aortic aneurysms (AAAs) has increased in western societies and complications often lead to life threatening events. There is still controversy regarding the management of medium sized AAAs. Therefore, novel biomarkers, besides aneurysmal diameter, are needed to assess aortic wall integrity and risk of rupture. Elastin is the key protein for maintaining stab...
