  1. 6. A Segmented Silicon Strip Detector for Photon-Counting Spectral Computed Tomography

    Författare :Cheng Xu; Hans Bornefalk; Mats Danielsson; Ami Altman; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; photon counting; spectral computed tomography; silicon strip detector; ASIC; energy resolution; cadmium telluride; charge sharing; Monte Carlo simulation; synchrotron;

    Sammanfattning : Spectral computed tomography with energy-resolving detectors has a potential to improve the detectability of images and correspondingly reduce the radiation dose to patients by extracting and properly using the energy information in the broad x-ray spectrum. A silicon photon-counting detector has been developed for spectral CT and it has successfully solved the problem of high photon flux in clinical CT applications by adopting the segmented detector structure and operating the detector in edge-on geometry.

  3. 7. Inhaled Nitric Oxide Therapy : Non-response and Rebound Response

    Författare :Luni Chen; Eddie Weitzberg; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology and intensive care; nitric oxide inhalation; rebound response; non-response; endothelin-1; COX inhibitor; prostaglandin; ARDS; endotoxin; oleic acid; Anestesiologi och intensivvård; Anaesthetics and intensive care; Anestesiologi och intensivvård; Clinical Physiology; klinisk fysiologi;

    Sammanfattning : Therapeutic inhaled nitric oxide (INO) has proved beneficial in patients with pulmonary hypertension. However, around 30-40% of the patients are non-responders to this therapy, and a life-threatening rebound response may occur during attempts to withdraw INO. LÄS MER

  4. 8. Treponema spp. in porcine skin ulcers : clinical aspects

    Författare :Frida Karlsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The hypothesis tested in this work is that bacteria of genus Treponema play a main role when shoulder ulcers and ear necrosis occur in an infectious or severe form, and perhaps also in other skin conditions in the pig. Samples were collected from pigs in 19 Swedish herds 2010-2011. LÄS MER

  5. 9. Protein and Cell Interactions with Nanostructured Surfaces

    Författare :Emma Westas; Chalmers tekniska högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bacteria; titanium dioxide; implant associated infections; metabolomics; cellular interactions; hydroxyapatite; immune complement activation; silica; nanoparticles; photocatalysis; protein adsorption; Nanostructured implants;

    Sammanfattning : A great challenge of today’s implant development is to construct a surface that promotes tissue integration and avoids bacterial colonization. To avoid implant related infections, many argue that a surface promoting strong cell adhesion and tissue integration in favour for bacterial adhesion would solve the problem, the so-called race for the surface concept.

  7. 10. Mesoporous Implants for Localized Controlled Drug Delivery

    Författare :Johan Karlsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; release kinetics; mesoporous titania; biomineralization; drug delivery; Biomedical implants; osseointegration; osteoporosis drugs; nanotopography; stem cells homing;

    Sammanfattning : The use of bone-anchored implants is today a routine treatment for patients with normal regenerative capacity. However, there is an ongoing development within implant research to improve the osseointegration of implants. LÄS MER
