  2. 1. Shock wave effects on the vascular endothelium

    Author : Anders Sondén; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Shock waves; cavitation; explosions; high-energy missile trauma; ESWL; laser; endothelial cells; cell membrane damage; cytoskeleton; adhesion molecules; reactive oxygen species;

    Abstract : A shock wave is a pressure wave with high amplitude and a velocity above sound. Man is exposed to shock waves (SWs) in connection with trauma, e.g. explosions and high-energy missiles and medical treatments such as extracorporeal lithotripsy (ESWL). READ MORE

  5. 3. Signal processing applied to acoustic distance estimation and sound classification

    Author : Lennart Olsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

    Abstract : The thesis treats some signal processing applications to retrieval of information from acoustic measurements. In the distance estimation applications (parts AI, A2, B and C) an acoustic signal propagates through a physical system and is modified according to some system parameter. READ MORE

    Author : Magnus Wagenius; Lund Institutionen för kliniska vetenskaper; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Urologi;

    Abstract : ConclusionsPaper I: Complications in Extracorporeal Shock Wave Lithotripsy (ESWL): A cohort study, conclusion: We conclude that there are few complications to modern ESWL treatment. 1 Hz should be used to reduce complications (p=0.025). As there is no indication that 1Hz is less effective than 1. READ MORE

  7. 5. Aspects of interventional endoscopic treatment of common bile duct stones

    Author : Fredrik Swahn; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ERCP;

    Abstract : Background: During the last 30 years, important changes have been introduced in the management of common bile duct stones (CBDS) which can be detected in about 10% of patients undergoing cholecystectomy because of symptomatic gallstone disease. Established minimally-invasive treatment options for CBDS include endoscopic retrograde cholangiopancreatography (ERCP) and laparoscopic common bile duct exploration. READ MORE
