  1. 1. Cerebral arterial pulsatility imaging using 4D flow MRI : methodological development and applications in brain aging

    Författare :Tomas Vikner; Anders Wåhlin; Anders Eklund; Jan Malm; Lars Nyberg; Susanne Schnell; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Magnetic resonance imaging; 4D flow MRI; medical image analysis; cerebral hemodynamics; arterial pulsatility; DCE MRI; blood-brain barrier; white matter lesions; perivascular spaces; cerebral small vessel disease; hippocampus; cognition; aging; biomedicinsk strålningsvetenskap; Biomedical Radiation Science;

    Sammanfattning : 4D flow magnetic resonance imaging (MRI) is increasingly recognizedas a versatile tool to assess arterial and venous hemodynamics. Cerebral arterial pulsatility is typically assessed by analyzing flow waveforms over the cardiac cycle, where flow amplitude is a function of cardiac output, central arterial stiffness, and cerebrovascular resistance and compliance.

  4. 3. The Potential of Driver Education to Reduce Traffic Crashes Involving Young Drivers

    Författare :Anders Nyberg; Nils Petter Gregersen; Lars Åberg; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Driver education; Young drivers; Public health; Traffic safety. Attitudes; Questionnnaires; Crashes; Social medicine; Socialmedicin;

    Sammanfattning : Traffic fatalities and injuries among young drivers as a result of road crashes constitute a serious public health problem. The ultimate goal of traffic safety work in Sweden has been formulated in Vision Zero, which includes an image of a future in which no one will be killed or seriously injured in traffic crashes.

  5. 4. Prostate cancer sensor : combining Raman spectroscopy and tactile resonance technology

    Författare :Morgan Nyberg; Anders Eklund; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Medical Engineering for Healthcare; Medicinsk teknik för hälsovård;

    Sammanfattning : Prostate cancer (PCa) is the most common cancer type among men in Sweden. The most prevalent curative treatment for PCa is radical prostatectomy (RP), i.e., complete surgical removal of the prostate. LÄS MER

  7. 5. Improved Assessment in Environmental Monitoring of POPs : Using monitoring data from the aquatic ecosystem and human milk

    Författare :Elisabeth Nyberg; Anders Bignert; Jochen Mueller; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental monitoring; temporal trends; power analysis; sampling strategy; PCBs; DDTs; HCHs; HCB; PCDD Fs; fish; bird eggs; blue mussels; human milk; miljökemi; Environmental Chemistry;

    Sammanfattning : The thesis deals with several aspects of monitoring of persistent organic contaminants (POPs) in biological matrices, for example choice of sample, sampling design, and statistical treatment of data both for temporal and spatial trends and for compliance towards a set target value. The efficiency has been evaluated through statistical power analyses. LÄS MER
