  1. 1. 4D flow MRI and modelling to assess cerebral arterial hemodynamics : method development and evaluation, with implementation in patients with symptomatic carotid stenosis

    Författare :Madelene Holmgren; Anders Eklund; Jan Malm; Anders Wåhlin; Sara Qvarlander; Ronnie Wirestam; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 4D flow MRI; carotid stenosis; cerebral blood flow; cerebral arterial compliance; cerebrovascular resistance; circleof Willis; computational fluid dynamics; magnetic resonance imaging; stroke; vascular disease; Neurology; neurologi;

    Sammanfattning : Blood flow measurements are important for understanding the development of cerebrovascular diseases. With 4D flow magnetic resonance imaging (4D flow MRI), simultaneous velocity measurements are obtained in all cerebral arteries in a scan of about ten minutes. However, 4D flow MRI is a relatively new technique. LÄS MER

  3. 2. Biochemical Control Aspects in Lignin Polymerization

    Författare :Anders Holmgren; Gunnar Henriksson; Liming Zhang; Jussi Sipilä; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lignin polymerization; DHP; Ascorbic Acid; NADH; template polymerization; melanin; Chemistry; Kemi;

    Sammanfattning : Lignins are produced by all vascular plants and they represent one of the most abundant groups of biopolymers in nature. Lignin chemistry research, which has been of great importance for the progress of pulping technologies, has been plagued by the difficulties of its isolation and characterization. LÄS MER

  4. 3. Klassrummets relationsetik : Det pedagogiska mötet som etiskt fenomen

    Författare :Anders Holmgren; Gun-Marie Frånberg; Kennert Orlenius; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Teacher-student relationship; Emmanuel Lévinas; relational ethics; responsibility; teaching; Saying; the Other; face; asymmetrical relationship; alterity; vulnerability; uncertainty; classroom communication; exposure; Pedgogical work; Pedagogiskt arbete;

    Sammanfattning : The main purpose of the present study is to explore how the ethical relationship between teacher and student in the classroom can be described and understood from the approach of the French philosopher Emmanuel Lévinas. I also examine the theoretical concepts that can be derived from Lévinas’ ideas in order to be able to interpret the manner in which this ethical relationship manifests itself in the classroom.

  5. 4. Metabolic risk markers and relative survival in patients with aortic stenosis requiring surgery

    Författare :Anders Holmgren; Ulf Näslund; Stefan Söderberg; Michael Henein; Rune Haaverstad; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; aortic stenosis; aortic valve surgery; coronary artery disease; prospective cohort study; risk markers; lipoprotein a ; apolipoproteins; proteomics; troponin T; C-reactive protein; relative survival; observed survival; kardiologi; Cardiology;

    Sammanfattning : Background: Aortic stenosis (AS) is the most common valve disorder requiring surgery in developed countries. The etiology of AS is only partly known.  Identification of new biomarkers in prospective studies could lead to novel insights in the etiology of AS, and possibly lead to improved clinical management.
