  1. 21. Computed Tomography of Acetabular Cup Wear and Effect of Surface Roughness on Wear and Oxidation of UHMWPE Hip Prostheses

    Författare :Anneli Jedenmalm; Ulf Gedde; André Stark; Karin Jacobson; Nicklas Axén; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hip prostheses; Computed Tomography; Surface roughness; UHMWPE; Wear; Coating; Gamma-irradiation; pin-on-disc; hip simulator; Medical engineering; Medicinsk teknik;

    Sammanfattning : Aseptic loosening is the most common complication in total hip replacement (5- 10% at 10 years follow up). The magnitude of the problem is illustrated by the fact that about one million hip prostheses are implanted worldwide each year. LÄS MER

  3. 22. Counting molecules in cell-free DNA and single cells RNA

    Författare :Kasper Karlsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :UMI;

    Sammanfattning : The field of Molecular Biology got started in earnest with the discovery of the molecular structure of DNA. This lead to a surge of interest into the relationships between DNA, RNA and proteins, and to the development of fundamental tools for manipulating those substances, such as cutting, ligating, amplifying, visualizing and size-selecting DNA.

  4. 23. Measurements in Idiopathic Normal Pressure Hydrocephalus : Computerized neuropsychological test battery and intracranial pulse waves

    Författare :Anders Behrens; Jan Malm; Anders Eklund; Eva Elgh; Niklas Lenfeldt; Marianne Juhler; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hydrocephalus; Normal Pressure; Neuropsychological tests; Neuropsychology; Reliability and validity; Software; Dementia; intracranial pressure; spinal puncture; cerebrospinal fluid pressure; pulse pressure waves; Blood flow velocity; Middle cerebral artery; Pulsatility index; Neurology; neurologi;

    Sammanfattning : Idiopathic Normal Pressure Hydrocephalus (INPH) is a condition affecting gait, cognition and continence. Radiological examination reveals enlarged ventricles of the brain. A shunt that drains CSF from the ventricles to the abdomen often improves the symptoms. LÄS MER

  5. 24. Consequences of amniocentesis and chorionic villus sampling for prenatal diagnosis

    Författare :Maria Cederholm; Karel Marsal; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obstetrics and gynaecology; Prenatal diagnosis; malformations; lung; labor; amnion; Obstetrik och kvinnosjukdomar; Obstetrics and women s diseases; Obstetrik och kvinnosjukdomar; Obstetrics and Gynaecology; obstetrik och gynekologi;

    Sammanfattning : Amniocentesis (AC) and chorionic villus sampling (CVS) are the principal methods for fetal karyotyping. The aim of this thesis was to evaluate psychological reactions and risks associated with the procedures.A semi-randomised study was made on 321 women, where AC (147) and CVS (174) at 10-13 weeks’ gestation were done trans-abdominally.

  7. 25. Sleep disordered breathing and hemodynamic function

    Författare :Ludger Grote; Göteborgs universitet; []
    Nyckelord :sleep apnea; hypertension; blood pressure; vascular function; exercise; arousal;

    Sammanfattning : This thesis addresses the association between sleep disordered breathing (SDB) and hemodynamic function. A cross sectional study in a sleep laboratory cohort (n=1190) demonstrated a dose-response relationship between the severity of SDB, expressed as respiratory disturbance index (RDI), and office blood pressure, heart rate, and the risk of hypertension.
