    Abstract : The incidence of abdominal aortic aneurysms (AAA) is increasing. The risk of rupture is related to diameter. However, rupture may occur also in small AAA. To evaluate the size of an aneurysm when related to the predicted normal aortic diameter might be a better predictor of risk. READ MORE

  2. 2. Design and Synthesis of Inhibitors Targeting BACE-1, an Aspartic Protease Involved in the Pathogenesis of Alzheimer’s Disease

    Author : Veronica Sandgren; Ingemar Kvarnström; Bertil Samuelsson; Thomas Olsson; Linköpings universitet; []
    Keywords : ;

    Abstract : Alzheimer’s disease (AD) is the most common form of dementia, occurring in an estimated 24 million people worldwide. Accumulation of amyloid-b peptides leads to development of plaques in the brain, which eventually stimulates hyperphosphorylation of tau proteins leading to tangles. This is believed to play a crucial role in the pathology of AD. READ MORE

    Abstract : Spectral analysis has advanced the last decades as a signal processing tool to extract significant information about certain properties of measured data. The practical use of spectral analysis techniques in time-series analysis has been emphasized in the immense amount of previous literature in the field and by a rapidly growing number of applications.
