AHA! stands for the Adaptive Hypermedia Architecture, an adaptive authoring and delivery platform developed as part of the Adaptive Hypermedia for All (or AHA!) project. (See http://aha.win.tue.nl/.) Adaptation in on-line textbooks makes it possible for learners to study the textbook in different ways without encountering difficulties. Link hiding and annotation guide users towards subjects the...

BACKGROUND Platelet-activating factor (PAF) is a phospholipid mediator with potent inflammatory activities. PAF stimulates IgA synthesis by B cells while IgA aggregates enhance PAF production by neutrophils and mesangial cells. These results led us to investigate blood PAF levels and plasma acetylhydrolase (AHA, the PAF catabolic enzyme) activity in patients with idiopathic IgA nephropathy (IgA...

This short (work in progress) paper describes recent updates to the “Adaptive Hypermedia Architecture” (AHA), developed at the Eindhoven University of Technology (TUE). AHA has been used for two courses at the TUE, and experimentally also in a kiosk information system. The next set of applications of AHA consists of an adaptive geological atlas and an adaptive and personalized version of the (c...

PAF is a potent inflammatory compound known to stimulate the release of various cytokines involved in rheumatic diseases. Elevated blood PAF levels are reported in these patients. We report that serum PAF acetylhydrolase activity (AHA) levels are decreased in patients with rheumatoid arthritis or osteoarthritis as compared to healthy controls. Serum and synovial fluid AHA levels were correlated...

OBJECTIVE To evaluate the effect of patient out-of-pocket costs on adherence to antihypertensive agents (AHA) in community-dwelling older adults covered by the public drug insurance plan in Quebec. METHODS This is a secondary analysis of data from the "Étude sur la santé des aînés" study (2005-2008) on community-dwelling older adults in Quebec aged 65 years and older (N=2,811). The final samp...

Acquired Hemophilia A (AHA) is a rare bleeding diathesis characterized by the development of autoantibodies against factor VIII (FVIII). About half of the cases are idiopathic and the other half are associated with autoimmune diseases, postpartum problems, infections, inflammatory bowel disease, drugs, lymphoproliferative disorders or solid tumors . AHA is associated with malignancies in 7-15% ...

The AHA/ASA has a longstanding commitment to support state-of-the-art scientific research in cardiovascular disease and stroke. The AHA/ASA has also developed a leadership role in translating cardiovascular science into internationally respected gu...

BACKGROUND Postprandial lipemia (PL) contributes to coronary artery disease. The fatty acid composition of dietary fats is potentially a modifiable factor in modulating PL response. METHODS This human postprandial study evaluated 3 edible fat blends with differing polyunsaturated to saturated fatty acids (P/S) ratios (POL = 0.27, AHA = 1.00, PCAN = 1.32). A cross-over design included mildly h...
