  1. 6. Gene dose imbalances in children with mental retardation

    Författare :Jacqueline Schoumans; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Mental retardation; MCA MR syndromes; cromosome abnormalities; subtelomeric FISH; comparative genomichybridization; array-CGH;

    Sammanfattning : Submicroscopic chromosome aberrations can cause mental retardation (MR), congenital malformations and miscarriage. It is difficult to estimate the contribution of cytogenetic abnormalities to MR because of relatively low detection sensitivity of conventional cytogenetic methods used in the diagnostic setting.

  3. 7. The mode of action of the radiosensitizing analogs metoclopramide and nicotinamide

    Författare :Anders Olsson; Lund Wallenberg Neurocentrum; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; medical instrumentation; metoclopramide; nicotinamide; apoptosis; radiosensitization; NAD; benzamide; DNA repair; Clinical physics; tomography; radiology; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

    Sammanfattning : This thesis provides the first attempt to study the nicotinamides and benzamides from a mode of action point of veiw. Understanding the effects on DNA repair, cell cycle control (proliferation) and cell death from these agents and in combination with ionizing radiation, provides a new opportunity to logically develop better approaches to sensitize already existing therapies via for example induction of apoptosis or inhibition of DNA repair.

  4. 8. Characterization, Activation and Reactivity of Natural Pozzolans for Use as Supplementary Cementitious Materials

    Författare :Amrita Hazarika; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reactivity; Volcanic Materials.; Clays; Pozzolans; Activation; SCMs;

    Sammanfattning : Supplementary cementitious materials (SCMs) represent one of the most practicable ways to reduce the negative environmental impact of cement. Natural pozzolans like clays and volcanic materials (VMs) offer promising alternatives to industrial by-products such as blast furnace slags and fly ashes, whose availability cannot meet the growing demand for SCMs globally.

  5. 9. Noninvasive assessment of cerebral circulation before, during and after carotid surgery

    Författare :Helene Zachrisson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Internal carotid artery disease; cerebrovascular hemodynamics; Carotid thrombendarterectomy; Duplex ultrasound; transcranial Doppler; Internal carotid artery disease;

    Sammanfattning : Non-invasive ultrasound investigations were evaluated in patients with carotid artery stenosis in comparison with radiological disease gradations and perioperative blood pressure measurements. The aim was to assess cerebrovascular hemodynamics before, during and after carotid thrombendarterectomy (CEA) in relation to the clinical outcome of the surgical intervention. LÄS MER

  7. 10. Preparedness for mass-casualty attacks on public transportation

    Författare :Annelie Holgersson; Ulf Björnstig; Britt-Inger Saveman; Dzenan Sahovic; Per Örtenwall; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; antagonism; disaster medicine; emergency response; emergency organizations; mass transit; preparedness; rescue work; security; terrorism; kirurgi; Surgery;

    Sammanfattning : Background: Public transportation constitutes a vulnerable sector in modern day society with a high probability of generating mass casualties if attacked. By preparing for mass-casualty attacks (MCAs), response can become more effective and public transportation can become a less rewarding target. LÄS MER
