    Författare :Charlotte Thornberg; [2000]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; medicinsk instrumentering; tomografi; radiologi; Klinisk fysiologi; body burden; Effective dose; Cs-137; urinary excretion; Cs-134; biological half-time; Chernobyl; breast milk; Medicine human and vertebrates ; internal irradiation; external irradiation; TLD; Clinical physics; radiology; medical instrumentation; tomography; Medicin människa och djur ; Physics; Fysik;

    Sammanfattning : From 1990 to 1998, estimations of the effective dose from external as well as internal irradiation from 137Cs and 134Cs were carried out for inhabitants in rural villages in the Bryansk region, Russia, highly contaminated due to the Chernobyl accident in 1986. The villages were situated about 180 km from the Chernobyl power plant and the deposition of 137Cs was in the range 0. LÄS MER

  3. 3. Proteins of the Inter-α-inhibitor Family Biosynthesis, Plasma Clearance and Interaction with Extracellular Matrix Components

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Aneta Kaczmarczyk; Uppsala universitet.; [2003]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; bikunin; inter-α-inhibitor; pre-α-inhibitor; intracellular processing; plasma clearance; extracellular matrix; binding; collagen; Biokemi; NATURAL SCIENCES Chemistry Biochemistry; NATURVETENSKAP Kemi Biokemi; Medical Biochemistry; medicinsk biokemi;

    Sammanfattning : Bikunin, a chondroitin sulfate-containing protein of 25 kDa, has protease inhibitory activity and occurs in the plasma in free and complexed form. In inter-α-inhibitor (IαI) and pre-a-inhibitor (PαI) it is covalently linked through its chondroitin sulfate (CS) chain to two or one other polypeptide of about 80 kDa – heavy chains 1 and 2 (H1, H2) and heavy chain 3 (H3) – respectively.

  4. 4. Amyloid beta aggregation kinetics : The role of intrinsic and extrinsic factors

    Detta är en avhandling från Lund University, Faculty of Science, Department of Biochemistry and Structural Biology

    Författare :Xiaoting Yang; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Alzheimer s disease; Abeta; aggregation; kinetics; secondary nucleation;

    Sammanfattning : Cerebral senile plaque is one of the main pathologies of Alzheimer's disease (AD). The amyloid cascade hypothesis suggests that the aggregation of amyloid beta (Abeta) peptide is involved in the pathogenesis of AD, which is supported by the fact that Abeta overexpression or production of more aggregation-prone variants lead to early-onset dementia.

  5. 5. The pharmacokinetics and pharmacodynamics of clevidipine, a new ultrashort-acting calcium antagonist, in different animal species and man

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Hans Ericsson; [1999]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacy; FARMACI; PHARMACY; FARMACI; Biopharmaceutics; biofarmaci;

    Sammanfattning : Clevidipine is a new ultrashort-acting calcium antagonist of the dihydropyridine type developed for reduction and control of blood pressure in connection with cardiac surgery. The aim of this thesis was to characterise the in vitro hydrolysis rate of clevidipine in different biological matrices and the pharmacokinetics and pharmacodynamics in animal species and various human populations.
