  1. 1. Erythropoiesis in anemia of rencl failure and malignancy : Studies on erythropoietin, iron, and transferrin receptor : by Soheir Beshara

    Författare :Soheir Beshara; Uppsala universitet; []
    Nyckelord :Medical sciences; erythropoiesis; anemia; renal transplantation; prostatic adenocarcinoma; erythropoietin; transferrin receptor; hemorheology positron emission tomography; iron hydroxide sucrose; pharmacokinetics; iron deficiency; 52Fe; 59Fe; red cell utilization; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Internal Medicine; invärtesmedicin;

    Sammanfattning : Erythropoietin (Epo) and iron are essential requirements for erythropoiesis. Serum transferrin receptor (S-TfR) is a marker of total erythropoiesis and tissue iron availability. In patients with renal insufficiency, successful renal transplantation leads to correction of anemia and improvement in erythropoiesis. LÄS MER

  3. 2. Rank Reduction with Convex Constraints

    Författare :Christian Grussler; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low-rank approximation; model reduction; non-convex optimization; Douglas-Rachford; matrix completion; overlapping norm; k-support norm; atomic norm;

    Sammanfattning : This thesis addresses problems which require low-rank solutions under convex constraints. In particular, the focus lies on model reduction of positive systems, as well as finite dimensional optimization problems that are convex, apart from a low-rank constraint. LÄS MER

  4. 3. Iron absorption and iron status related to diet : an experimental and epidemiological study

    Författare :Per Tidehag; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; iron status; iron absorption; bioavailability; dietary fiber; phytate; calcium; radioiron; diet;

    Sammanfattning : The absorption of iron from the diet is a major determinant of the iron status of an individual. Accurate measures of iron absorption are thus essential in the determination of the effects of diet composition on iron absorption and status. LÄS MER
