  1. 1. Treatment of Temporomandibular Disorders of Arthrogeneous Origin. Controlled double-blind studies of a non-steroidal anti-inflammatory drug and a stabilisation appliance

    Författare :EwaCarin Ekberg; Institutionen för hälsovetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Temporomandibular Joint Disorders; Randomized Controlled Trials; Non-steroidal Anti-inflammatory Agents; Occlusal Splints; Treatment Outcome; Mandibular Condyle Radiography; Subtraction Technique; Radiographic Image Enhancement; Causality; Odontology; stomatology; Odontologi;

    Sammanfattning : The aim of this thesis was to prospectively evaluate the short-term effect of a non-steroidal anti-inflammatory drug (diclofenac sodium, Voltaren) and stabilisation appliance in controlled trials of patients with temporomandibular disorders (TMD) of arthrogeneous origin. The active treatments were compared to placebo in the study of diclofenac and to a control appliance in the other study. LÄS MER

  2. 2. Proposing Combined Approaches to Remove ECG Artifacts from Surface EMG Signals

    Författare :Sara Abbaspour; Maria Lindén; Urban Wiklund; Mälardalens högskola; []

    Sammanfattning : Electromyography (EMG) is a tool routinely used for a variety of applications in a very large breadth of disciplines. However, this signal is inevitably contaminated by various artifacts originated from different sources. LÄS MER

  3. 3. On contrast-enhanced magnetic resonance angiography of the aortoiliac arteries

    Författare :Johan Wikström; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Magnetic resonance imaging; Magnetic resonance angiography; Contrast media; Arteriosclerosis; Iliac artery; Blood pressures; Onkologi; Oncology; Onkologi; radiologi; Radiology;

    Sammanfattning : In contrast-enhanced magnetic resonance angiography (CE-MRA),vascular signal is produced by the acquisition of a T1-weighted magnetic resonance imaging scan while the presence of a contrast agent induces a low T1 in blood. In this thesis,CE-MRA of the aortoiliac arteries was evaluated. LÄS MER

  4. 4. Corrections for improved quantitative accuracy in SPECT and planar scintigraphic imaging

    Författare :Anne Larsson; Lennart Johansson; Katrine Åhlström Riklund; Bertil Axelsson; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Quantitative SPECT; scintigraphic imaging; attenuation correction; scatter correction; collimator-detector response; septal penetration; background correction; Monte Carlo simulation; Radiological physics; Radiofysik;

    Sammanfattning : A quantitative evaluation of single photon emission computed tomography (SPECT) and planar scintigraphic imaging may be valuable for both diagnostic and therapeutic purposes. For an accurate quantification it is usually necessary to correct for attenuation and scatter and in some cases also for septal penetration. LÄS MER

  5. 5. Subtracted Approaches to Gene Expression Analysis in Atherosclerosis

    Författare :Stina Boräng; KTH; []
    Nyckelord :Representational Difference Analysis; atherosclerosis; gene expression profiling;

    Sammanfattning : Gene expression analysis has evolved as an extensive toolfor elucidation of various biological and molecular eventsoccurring in different organisms. A variety of techniques andsoftware tools have been developed to enable easier and morerapid means of exploring the genetic information. LÄS MER
